![]() Set TIMESTAMP columns to use CURRENT_TIMESTAMP when a record is updated (MySQL).Ĭreate a virtual generated column (MySQL).Ĭreate an identity column with specified sequence options (PostgreSQL).ĭefines the precedence of sequence values over input for an identity column (PostgreSQL). Set TIMESTAMP columns to use CURRENT_TIMESTAMP as default value. Make the column "invisible" to SELECT * queries (MySQL).Īllow NULL values to be inserted into the column.Ĭreate a stored generated column (MySQL / PostgreSQL). Set the starting value of an auto-incrementing field (MySQL / PostgreSQL). Place the column "first" in the table (MySQL). Specify a "default" value for the column. Specify a collation for the column (MySQL/PostgreSQL/SQL Server).Īdd a comment to a column (MySQL/PostgreSQL). Specify a character set for the column (MySQL). Set INTEGER columns as auto-incrementing (primary key). Place the column "after" another column (MySQL). This list does not include index modifiers: Modifier The following table contains all of the available column modifiers. To get started, execute the schema:dump command: If you would like, you may "squash" your migrations into a single SQL file. This can lead to your database/migrations directory becoming bloated with potentially hundreds of migrations. Migration stubs may be customized using stub publishing.Īs you build your application, you may accumulate more and more migrations over time. The given path should be relative to your application's base path. If you would like to specify a custom path for the generated migration, you may use the -path option when executing the make:migration command. Otherwise, you may simply specify the table in the migration file manually. If Laravel is able to determine the table name from the migration name, Laravel will pre-fill the generated migration file with the specified table. Laravel will use the name of the migration to attempt to guess the name of the table and whether or not the migration will be creating a new table. Php artisan make:migration create_flights_table ![]() ![]() Each migration filename contains a timestamp that allows Laravel to determine the order of the migrations: The new migration will be placed in your database/migrations directory. You may use the make:migration Artisan command to generate a database migration. Typically, migrations will use this facade to create and modify database tables and columns. The Laravel Schema facade provides database agnostic support for creating and manipulating tables across all of Laravel's supported database systems. If you have ever had to tell a teammate to manually add a column to their local database schema after pulling in your changes from source control, you've faced the problem that database migrations solve. You can change the main version (top right) to a previous version and compare older methods with their predecessor.Migrations are like version control for your database, allowing your team to define and share the application's database schema definition. Green marks contents that were added (in this case title text changed and field registered was added).Each method shows the actual difference compare to its predecessor.The main navigation mark all changed methods with a green bar.In the example, click on the dropdown box in the top right (the main version) and select Compare all with predecessor. Frontend Developer can thus simply see what have changed and update their code accordingly. This makes it possible to compare a methods' version with its predecessor. Inheritance only works with one parent, using multiple levels would make the inline code unreadable and changes very complex.Ī useful feature provided by apiDoc is the ability to maintain the documentation for all previous versions and the latest version of the API. The apiGroup and apiPermission use similar syntax, but they do not inherit any parameters except for the title and description (in combination with apiVersion). To create an inheritable block, use apiDefine. ![]() The complete documentation of UserNotFoundError will be included in both GET and PUT methods in the generated output. Which can be referenced repeatedly using UserNotFoundError. In this example, is used to define a block named UserNotFoundError, Demo This is an example documentation: Go to live demo See presentation Getting started PrefaceĪll examples in this document use the Javadoc-Style (can be used in C#, Go, Dart, Java, JavaScript, PHP, TypeScript and all other Javadoc capable languages): /**įor other languages use their specific multiline comment code:Įrlang (% within the comment is optional) % Lastname of the User.
