Overview Through padrino-lazy, we can include some common properties shared between the model object used a base model object Padrino is very good framework, and almost follows the DRY principle (Don’t Repeat Yourself) When we need to have some common properties shared between the model object of our ORM, using the generator padrino-gen, We can only include these properties in each model to generate. I hope this idea will be included in Padrino Framework. Principle / Step
- generate a model
- convert the model into base model ( move this model into lib/ folder)
- save config file with model base’s list
- generate a model from base model
- generate a migration file
Usage Step 1-2-3
$ padrino-lazy base –c config_file –b base_model_name –f field_to_create
Step 4-5
$ padrino-lazy model –c config_file –b base_model_name –f field_to_create –m model_name
Install
gem install padrino-lazy –pre
Example
$ padrino-lazy base –c config –b BaseModel –f “create_at:datetime is_active:boolean”
now we have lib/base_model.rb class BaseModel
include DataMapper::Resource
property ,
property :id, Serial property :create_at, DateTime property :is_active, Boolean
end
config/config.yml
--- - base: BaseModel fields: create_at:datetime is_active:boolean
$ padrino-lazy model –c config –b BaseModel –f “name:string have_children:boolean born:date foo:integer” –m User
app/models/user.rb
class User < BaseModel
property ,
property :name, String property :have_children, Boolean property :born, Date property :foo, Integer end
db/migrate/001_create_users.rb
migration 1, :create_users do up do create_table :users do column :id, Integer, :serial => true column :name, String column :have_children, Boolean column :born, Date column :foo, Integer end end
down do drop_table :users end end
db/migrate/002_add_basic_model_to_user.rb
migration 2, :add_basic_model_to_user do up do modify_table :users do add_column :name, String add_column :have_children, Boolean add_column :born, Date add_column :foo, Integer end end
down do modify_table :users do drop_column :name drop_column :have_children drop_column :born drop_column :foo end end end
Known issue
- VERY VERY alpha code !! (thanks to my pig/lazy side :D )
- —f options need dobule quote around fields
- —b write in CamelCase
- TESTING only with datamapper and activerecord into linux machine
TODO:
- Test all code !
- Use Padrino::Generators instead of Commander
- Default config file name (very lazy :P )
