Learn how to insert data into your SQLite database using the put method from Cupboard's DatabaseCompartment class.
- [Instructor] Inserting data into…your database is trivial using Cupboard.…We're going to update the data source classes…createRecipe method.…Previously with SQLite Raw, we had to use the content values…class in order to insert a new record.…Now, we can rely on the abstraction layer that Cupboard…provides, and achieve the same result in one line of code.…Here on line 40, where we have our Row ID variable defined,…we're going to replace the zero with a call to Cupboard…and let's go ahead and click alt enter, so that we can…static import the cupboard method.…
Then, we're going to call, with database.…Passing in our instance of the database.…And finally, we will call the put method, and we're going…to pass in the recipe that we received as a parameter.…If we take a look at the source code for the put method,…let me just click here,…we can see that it takes an entity, we can see that it…does the work of creating the content values for us…starting on line 212, and then inserting the record.…
So there's no magic happening here when you use Cupboard.…
To begin, Annyce Davis reviews using the de facto data persistence solution available on Android: SQLite. She takes you through basic SQLite concepts—such as how to create a database wrapper and insert data into a table—as well as a few more advanced topics. Next, she covers working with Cupboard, an open-source project dedicated to simplifying your SQLite interactions. To wrap up, she dives into working with Realm, an object database solution designed with mobile devices in mind. Throughout the course, Annyce discusses establishing relationships between database tables, creating and running queries, as well as performing data migrations.
