Laravel is a popular PHP framework that is widely used in web development. During the development process, it is likely that the table and field names in the database need to be modified. This article will introduce how to modify field names in Laravel.
Migration is a tool for managing databases in Laravel, which can create, modify, and delete tables and fields. You can use the following command to create a migration:
php artisan make:migration rename_column_table --table=tablename
Where, rename_column_table
is the name of the migration, tablename
is the name of the table to be modified. After executing the above command, Laravel will create a new migration file in the database/migrations
directory.
Open the newly created migration file and use the following code to modify the field name in the table:
public function up() { Schema::table('tablename', function($table) { $table->renameColumn('old_column_name', 'new_column_name'); }); }
In the above code, tablename
is the name of the table to be modified, old_column_name
is the field name to be modified, new_column_name
is the modified field name.
Run the following command to perform migration:
php artisan migrate
In addition to using migration, you can also use [Laravel Schema Builder](https:// Modify the field name using the modification command provided in laravel.com/docs/8.x/migrations). You can use the following code:
Schema::table('tablename', function($table) { $table->renameColumn('old_column_name', 'new_column_name'); });
In the above code, tablename
is the table name to be modified, old_column_name
is the field name to be modified, new_column_name
is the modified field name.
Execute the above code to modify the field name.
In short, during the development process, you need to flexibly use the database management tools provided by Laravel and reasonably modify table and field names to improve development efficiency and code quality.
