Use ModelGenerator and CURD Generator to automatically generate the corresponding model code and add, delete, modify, and query code.

3. when the tables in the database need to be modified, you can use migration:

Execute the command in the project:./yii migrate/create "custom name"

A new folder migrations is generated in the project to open the files in the folder:

class m150225_022640_modify_book_table extends Migration{  public function up()  {    $this->addColumn("book", "book_desc", yii\db\mssql\Schema::TYPE_TEXT);  }  public function down()  {    echo "m150225_022640_modify_book_table cannot be reverted.\n";    return false;  }}

Use the command:./yii migrate in the command line to execute the up function in the script.
Use the command:./yii migrate/down in the command line to execute the down function in the script.
