Why trade CFDs? If you want only a subset of the Post s you can add extra constraints to the ParseQuery returned by getQuery. The code would look something like:. For more details on ParseQuery , please look at the query portion of this guide. Parse also supports float , java. Overall, the following types are allowed for each field in your object:. We do not recommend storing large pieces of binary data like images or documents on ParseObject.
We recommend you use ParseFile s to store images, documents, and other types of files. You can do so by instantiating a ParseFile object and setting it on a field.
See Files for more details. For more information about how Parse handles data, check out our documentation on Data. Parse is designed to get you up and running as quickly as possible. You can access all of your data using the ParseObject class and access any field with get.
In mature codebases, subclasses have many advantages, including terseness, extensibility, and support for autocomplete. Subclassing is completely optional, but can transform this code:.
Adding methods to your ParseObject subclass helps encapsulate logic about the class. You can add accessors and mutators for the fields of your ParseObject easily. Declare the getter and setter for the field as you normally would, but implement them in terms of get and put. The following example creates a displayName field in the Armor class:. You can now access the displayName field using armor. This allows your IDE to provide autocompletion as you develop your app and allows typos to be caught at compile-time.
Accessors and mutators of various types can be easily defined in this manner using the various forms of get such as getInt , getParseFile , or getMap. If you need more complicated logic than simple field access, you can declare your own methods as well:. You should create new instances of your subclasses using the constructors you have defined.
Your subclass must define a public default constructor that does not modify fields of the ParseObject , which will be used throughout the Parse SDK to create strongly-typed instances of your subclass. To create a reference to an existing object, use ParseObject. You can get a query for objects of a particular subclass using the static method ParseQuery. The following example queries for armors that the user can afford:.
This means you can retain a ParseObject during configuration changes, or pass objects to other components through Bundle s. To achieve this, depending on the context, use either Parcel writeParcelable Parcelable, int or Bundle putParcelable String, Parcelable.
For instance, in an Activity ,. ParseObject will parcel its internal state, along with unsaved children and dirty changes. There are, however, a few things to be aware of when parceling objects that have ongoing operations, like save or delete. When the Local Datastore is enabled, parceling a ParseObject is a safe operation even if there are ongoing save or delete operations. The unparceled object, being a different instance than the source object,. The unfortunate consequence is that keys that were dirty before saving will still be marked as dirty for the unparceled object.
This means, for instance, that any future call to saveInBackground will send these dirty operations to the server again. This can lead to inconsistencies for operations like increment , since it might be performed twice.
By default, ParseObject implementation parcels everything that is needed. If your subclasses have stateful information that you would like to keep when parceling, you can simply override onSaveInstanceState Bundle and onRestoreInstanceState Bundle :. There are many other ways to retrieve data with ParseQuery - you can retrieve many objects at once, put conditions on the objects you wish to retrieve, cache queries automatically to avoid writing that code yourself, and more.
The ParseQuery offers different ways to retrieve a list of objects rather than just a single object. The general pattern is to create a ParseQuery , put conditions on it, and then retrieve a List of matching ParseObject s using the findInBackground method with a FindCallback. For example, to retrieve scores with a particular playerName , use the whereEqualTo method to constrain the value for a key:.
There are several ways to put constraints on the objects found by a ParseQuery. You can filter out objects with a particular key-value pair with whereNotEqualTo :. You can give multiple constraints, and objects will only be in the results if they match all of the constraints.
You can limit the number of results with setLimit. By default, results are limited to In the old Parse hosted backend, the maximum limit was 1,, but Parse Server removed that constraint:.
If you want exactly one result, a more convenient alternative may be to use getFirst or getFirstInBackground instead of using find. You can skip the first results with setSkip. In the old Parse hosted backend, the maximum skip value was 10,, but Parse Server removed that constraint. This can be useful for pagination:. For sortable types like numbers and strings, you can control the order in which results are returned:.
If you want to retrieve objects matching several different values, you can use whereContainedIn , providing a collection of acceptable values. This is often useful to replace multiple queries with a single query. For example, if you want to retrieve scores made by any player in a particular list:.
If you want to retrieve objects that do not match any of several values you can use whereNotContainedIn , providing an array of acceptable values. For example, if you want to retrieve scores from players besides those in a list:.
If you want to retrieve objects that have a particular key set, you can use whereExists. Conversely, if you want to retrieve objects without a particular key set, you can use whereDoesNotExist. You can use the whereMatchesKeyInQuery method to get objects where a key matches the value of a key in a set of objects resulting from another query.
The query would look like:. Conversely, to get objects where a key does not match the value of a key in a set of objects resulting from another query, use whereDoesNotMatchKeyInQuery.
For example, to find users whose hometown teams have losing records:. You can restrict the fields returned by calling selectKeys with a collection of keys. To retrieve documents that contain only the score and playerName fields and also special built-in fields such as objectId , createdAt , and updatedAt :. The remaining fields can be fetched later by calling one of the fetchIfNeeded variants on the returned objects:.
Use whereStartsWith to restrict to string values that start with a particular string. Queries that have regular expression constraints are very expensive. Refer to the Performance Guide for more details.
You can use whereFullText for efficient search capabilities. Text indexes are automatically created for you. Your strings are turned into tokens for fast searching. Note: Full Text Search can be resource intensive. There are several ways to issue queries for relational data.
If you want to retrieve objects where a field matches a particular ParseObject , you can use whereEqualTo just like for other data types. For example, if each Comment has a Post object in its post field, you can fetch comments for a particular Post :. If you want to retrieve objects where a field contains a ParseObject that matches a different query, you can use whereMatchesQuery. In order to find comments for posts containing images, you can do:.
If you want to retrieve objects where a field contains a ParseObject that does not match a different query, you can use whereDoesNotMatchQuery. In order to find comments for posts without images, you can do:. In some situations, you want to return multiple types of related objects in one query.
You can do this with the include method. You can also do multi level includes using dot notation. You can issue a query with multiple fields included by calling include multiple times. If you have enabled the local datastore by calling Parse. To do this, call the fromLocalDatastore method on the query. You can query from the local datastore using exactly the same kinds of queries you use over the network. For example, if you call deleteEventually , on an object, it will no longer be returned from these queries.
The easiest way to do this is with the local datastore. When you pin objects, you can attach a label to the pin, which lets you manage a group of objects together. For example, to cache the results of the query above, you can call pinAllInBackground and give it a label. Now when you do any query with fromLocalDatastore , these objects will be included in the results if they still match the query.
ParseQuery lets you choose whether to query the network fromNetwork or the local datastore fromLocalDatastore or fromPin label to query just a subset. It is also possible to chain both requests, or execute them in parallel.
For example, to try the network and then fall back to cached data if the network is not available:. You can do the following operations on the cache:. Note: In the old Parse hosted backend, count queries were rate limited to a maximum of requests per minute. They also returned inaccurate results for classes with more than 1, objects. But, Parse Server has removed both constraints and can count objects well above 1, If you just need to count how many objects match a query, but you do not need to retrieve all the objects that match, you can use count instead of find.
For example, to count how many games have been played by a particular player:. If you want to block the calling thread, you can also use the synchronous query. If you want to find objects that match one of several queries, you can use ParseQuery. For instance if you want to find players who either have a lot of wins or a few wins, you can do:. Note that we do not, however, support GeoPoint or non-filtering constraints e. At the core of many apps, there is a notion of user accounts that lets users access their information in a secure manner.
We provide a specialized user class called ParseUser that automatically handles much of the functionality required for user account management. ParseUser is a subclass of the ParseObject , and has all the same features, such as flexible schema, automatic persistence, and a key value interface. All the methods that are on ParseObject also exist in ParseUser.
The difference is that ParseUser has some special additions specific to user accounts. ParseUser has several properties that set it apart from ParseObject :. Keep in mind that if you set username and email using the setters, you do not need to set it using the put method.
The first thing your app will do is probably ask the user to sign up. The following code illustrates a typical sign up:. This call will asynchronously create a new user in your Parse App. Before it does this, it checks to make sure that both the username and email are unique. Also, it securely hashes the password in the cloud using bcrypt.
We never store passwords in plaintext, nor will we ever transmit passwords back to the client in plaintext. Subsequent updates to a user can be done by calling save.
The signUpInBackground method comes in various flavors, with the ability to pass back errors, and also synchronous versions. As usual, we highly recommend using the asynchronous versions when possible, so as not to block the UI in your app.
You can read more about these specific methods in our API docs. The most likely case is that the username or email has already been taken by another user. You should clearly communicate this to your users, and ask them try a different username. You are free to use an email address as the username.
Simply ask your users to enter their email, but fill it in the username property — ParseUser will work as normal. Of course, after you allow users to sign up, you need be able to let them log in to their account in the future. To do this, you can use the class method logInInBackground.
Email verification adds the emailVerified key to the ParseUser object. Parse then emails the user a link which will set emailVerified to true. There are three emailVerified states to consider:. It would be bothersome if the user had to log in every time they open your app. You can avoid this by using the cached currentUser object. Whenever you use any signup or login methods, the user is cached on disk.
You can treat this cache as a session, and automatically assume the user is logged in:. Being able to associate data and objects with individual users is highly valuable, but sometimes you want to be able to do this without forcing a user to specify a username and password.
An anonymous user is a user that can be created without a username and password but still has all of the same capabilities as any other ParseUser.
After logging out, an anonymous user is abandoned, and its data is no longer accessible. You can create an anonymous user using ParseAnonymousUtils :. You can convert an anonymous user into a regular user by setting the username and password, then calling signUp , or by logging in or linking with a service like Facebook or Twitter.
The converted user will retain all of its data. To determine whether the current user is an anonymous user, you can check ParseAnonymousUtils. Anonymous users can also be automatically created for you without requiring a network request, so that you can begin working with your user immediately when your application starts. When you enable automatic anonymous user creation at application startup, ParseUser. The user will automatically be created in the cloud the first time the user or any object with a relation to the user is saved.
Enabling automatic user creation makes associating data with your users painless. For example, in your Application. This method will ensure the session token is valid before setting the current user.
The ParseUser class is secured by default. Data stored in a ParseUser can only be modified by that user. By default, the data can still be read by any client. Thus, some ParseUser objects are authenticated and can be modified, whereas others are read-only.
Specifically, you are not able to invoke any of the save or delete type methods unless the ParseUser was obtained using an authenticated method, like logIn or signUp. This ensures that only the user can alter their own data.
The ParseUser obtained from getCurrentUser will always be authenticated. If you need to check if a ParseUser is authenticated, you can invoke the isAuthenticated method. You do not need to check isAuthenticated with ParseUser objects that are obtained via an authenticated method. The same security model that applies to the ParseUser can be applied to other objects. For any object, you can specify which users are allowed to read the object, and which users are allowed to modify an object.
To support this type of security, each object has an access control list , implemented by the ParseACL class. The simplest way to use a ParseACL is to specify that an object may only be read or written by a single user. To create such an object, there must first be a logged in ParseUser.
Thus, to create a private note that can only be accessed by the current user:. This note will then only be accessible to the current user, although it will be accessible to any device where that user is signed in. This functionality is useful for applications where you want to enable access to user data across multiple devices, like a personal todo list.
Permissions can also be granted on a per-user basis. This allows patterns like posting comments on a message board. For example, to create a post that can only be edited by its author, but can be read by anyone:. In the code above, the second parameter to setDefaultACL tells Parse to ensure that the default ACL assigned at the time of object creation allows read and write access to the current user at that time.
Without this setting, you would need to reset the defaultACL every time a user logs in or out so that the current user would be granted access appropriately. With this setting, you can ignore changes to the current user until you explicitly need to grant different kinds of access. Default ACLs make it easy to create apps that follow common access patterns. An application like Twitter, for example, where user content is generally visible to the world, might set a default ACL such as:.
Operations that are forbidden, such as deleting an object that you do not have write access to, result in a ParseException. For security purposes, this prevents clients from distinguishing which object ids exist but are secured, versus which object ids do not exist at all. In such cases, our library provides a way to let them securely reset their password. By doing this, you can opt to have users use their email as their username, or you can collect it separately and store it in the email field.
Note that the messaging in this flow will reference your app by the name that you specified when you created this app on Parse. In addition, you can use get to get a ParseUser by id. Associations involving a ParseUser work right of the box. To store a new post for a user and retrieve all their posts:. Parse provides an easy way to integrate Facebook with your application. Using our Facebook integration, you can associate an authenticated Facebook user with a ParseUser.
These instructions are for Facebook SDK 4. This allows users of apps that support Facebook login to sign in directly through the Facebook app, using credentials that are already on the device.
If the Facebook app is not installed, the default dialog-based authentication will be used. If your Activity is already using onActivityResult , you can avoid requestCode collisions by specifying your own request code offset when initializing ParseFacebookUtils. Otherwise, a sensible default activityCode will be used. There are two main ways to use Facebook with your Parse users: 1 logging in as a Facebook user and creating a ParseUser , or 2 linking Facebook to an existing ParseUser.
In order to display the Facebook login dialogs and activities, the current Activity must be provided often, the current activity is this when calling logInWithReadPermissionsInBackground from within the Activity as we have done above.
When logging in, you can only use read permissions. See our documentation below about requesting additional permissions read or publish. If you want to associate an existing ParseUser to a Facebook account, you can link it like so:.
The steps that happen when linking are very similar to log in. The difference is that on successful login, the existing ParseUser is updated with the Facebook information. Future logins via Facebook will now log the user into their existing account. As of v3. To request additional permissions, you may call ParseFacebookUtils.
The first monthly payment will be charged on day of purchase or shortly thereafter. Blockout dates are dates when you are unable to enter the parks with your Annual Pass. The most expensive Incredi-Pass has no blockout dates, while the least-expensive Pixie Dust Pass has quite a few:.
It is also the most expensive, but it comes with zero blockout dates. With the pass, you can visit any day you want as long as you have a Park Pass reservation. There have been some changes to how many Park Pass Reservations you can have. Annual Passholders with a Disney Resort hotel reservation can make theme park reservations for the entire length of their stay. Annual Passholders at Disney World can also purchase individual Lightning Lane selections on the day of their visit.
If you purchase your Annual Pass via any method other than in-person on Disney property, you will receive a voucher that you must redeem once you arrive. You can link your voucher to your My Disney Experience account the same way you can a ticket so you can make your Park Pass Reservations.
Note: there are reports of Cast Members not asking to see the Annual Pass at check-in but Disney does state that you must present it so it is better to be prepared.
At a later date, Disney will roll out upgrades via their website and in the My Disney Experience App. In the past, there have been other perks like free MagicBands offered with Annual Passes. However, at this time, these are the perks available with Annual Passes.
Disney World Annual Passholders have access to dedicated support services. You can always find the current AP resort discounts as well as information on what discounts were offered in the past on our guide to Disney World discounts.
As long as you have one at check-in, you can use the discount. Annual Passholders have access to dining discounts at restaurants throughout the entire Walt Disney World resort. Before the parks closed, there was another option for dining discounts called Tables in Wonderland.
