Symfony commands to create new backend module.
By following symfony commands we can create module in backend. We need to run following commands in command prompt or git shell if you are using git. First create table for your module and run schema.
symfony propel-generate-crud myapp article Article
Symfony will read the definition of Article class in the schema.yml and creates a set of templates and actions based on it in the myapp/modules/article directory.
symfony propel-init-admin backend article Article
Above command is to Initiate an administration module. You can build an administration on a per-module basis.
Note: myapp will be your app in which you want to create module and article is table name and Article is model name.
