![]() ![]() You only need to place items in the read and write arrays if you wish to override the values from the main mysql array. The rest of the database options for the read and write connections will be merged from the main mysql configuration array. The read and write keys have array values containing a single key: host. Note that three keys have been added to the configuration array: read, write and sticky. After the database has been created, you may easily configure your environment variables to point to this database by placing the absolute path to the database in the DB_DATABASE environment variable: You can create a new SQLite database using the touch command in your terminal: touch database/database.sqlite. SQLite databases are contained within a single file on your filesystem. However, you are free to modify your database configuration as needed for your local database. Examples for most of Laravel's supported database systems are provided in this file.īy default, Laravel's sample environment configuration is ready to use with Laravel Sail, which is a Docker configuration for developing Laravel applications on your local machine. Most of the configuration options within this file are driven by the values of your application's environment variables. In this file, you may define all of your database connections, as well as specify which connection should be used by default. That is all! If you start the application now, you will see the data loaded in the control.The configuration for Laravel's database services is located in your application's config/database.php configuration file. In that method, we call the method of the class and pass the collection to it. Finally, we define the method, which will be called on the event of the page. This allows us to bind the attribute of the control to the property of the page. We use the constructor to initialize the collection and set the DataContext property of the page to the instance of the page. Private async void Page_Loaded(object sender, RoutedEventArgs e)Īwait DatabaseConnector.LoadRecordsAsync(Items) Var descriptionOrdinal = reader.GetOrdinal("Description") Var nameOrdinal = reader.GetOrdinal("Name") Using(var reader = await command.ExecuteReaderAsync()) SQLiteCommand command = new SQLiteCommand("SELECT * FROM Data", connection) ![]() Using(SQLiteConnection connection = new SQLiteConnection("Data Source=Assets/uwp.db Version=3")) Public static async Task LoadRecordsAsync(ObservableCollection items) Open the DatabaseConnector.cs file and replace its content with the following code: using ĭouble-click on the project name in the and select. In the right-click on the node and select. For that, however, we first need to add an SQLite package to our project. Now, we are going to create a routine for loading records from the database. Additionally, we defined a handler for the event that we will use to load the records from the database. Finally, we defined two elements and bound their attributes to the and properties of the class. That allows us proper binding to the class properties. We set the value of the attribute of the to, which is the name of the container class we have just created. We bound the attribute to property, which we will define later in the file. In the code, we added a new control with the name. Replace the content of the file with the following XAML code: In the double-click on the file to open it. Next, we are going to add a ListView control to the main page and define how the content of each item should be shown. Next, in the, double-click on the file to open it and replace the content of the file with the following code: namespace ListViewSQLiteĪs you can see, the class has two string properties and mimicking the structure of the database’s table. ![]()
