Models

Padrino provides generator support for quickly creating new models within your Padrino application. Note that the models (and migrations) generated are specifically tailored towards the ORM component and testing framework chosen during application generation.

Run model generators from the root of a Padrino project, the folder that contains config/boot.rb. They read project settings, such as the ORM and test framework, from the .components file that the project generator creates, so they will not work in a project without it.

Using the model generator is as simple as:

$ padrino g model User

You can also specify desired fields to be contained within your User model:

$ padrino g model User name:string age:integer email:string

With ActiveRecord, a field can take a third segment: index adds an index on the column and uniq adds a unique index. A references (or belongs_to) field adds a <name>_id column, and takes the same segment:

$ padrino g model Post title:string slug:string:uniq user:references:index

The other ORMs ignore the third segment.

The model generator will create multiple files within your application and based on your ORM component. Usually the model file will generate files similar to the following:

• Model definition file (models/user.rb)
• Migration declaration (db/migrate/xxx_create_users.rb)
• Model unit test file (test/models/user_test.rb)

You can define as many models as you would like in a Padrino application using this generator.

You can destroy models that you created via the destroy option and setting it to true. Default is false.

$ padrino g model User -d

This remove all created model files.
