Backendless

  When working with data, particularly user-submitted data, you often need to validate it. For example, if we are creating a database in which there is a “site” field and corresponding IP address field, it would be very useful to ensure that the data written to these fields is in the appropriate format.

Once a user of a Backendless-powered app logs in, a session is established. For a variety of reasons, including application security, it is best not to allow users to remain logged in indefinitely. Therefore, every session has an inactivity timeout timer that is reset with every new API call made within the session. When the…

In another article, we reviewed how to register app users with the API. By default, a Backendless backend declares a user entity with three properties: email, password, and name. The “email” property is configured as identity by default, meaning its value should be passed into the login API request.

Connecting users with their related data is a key function of user management. When you register (or update) a user object, you may need to create a relation between the user and some other entity/object stored in your Backendless Database. Since a user object is structurally a collection of properties, it is very easy to…

In another article discussing user management, we covered how to use the user registration API to register users for your app. When registering a user, your app sends a collection of user registration properties to the server. Values for these properties typically come from a registration form in your app. Some form fields may be…

There will often be times when you want to delete users from your database, whether it’s to purge old users or to allow users to delete their own account. Backendless supports two methods for deleting a user: using the API or using Backendless Console. The API approach is described using the code below.

In another article, we wrote about how to change a user’s password using Backendless Console. There are also ways to change a user’s password using API. In this post, we will review the API that can be used to change the password if a user can log in.

The ability to update a user account is a common use-case for user management in applications. Either the users themselves or the admin may need to update user properties. Backendless provides the API for updating user accounts, although app admins/developers can do so using Backendless Console as well.

There are instances when you need to disable user registrations for your app. This may be needed if you are going to run a limited beta test of your application and allow only some users in. Alternatively, your app may require manual user registration (or you plan to import users from another system).
