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
1
| $ padrino-lazy base --c config_file --b base_model_name --f field_to_create |
Step 4-5
1
| $ padrino-lazy model --c config_file --b base_model_name --f field_to_create --m model_name |
Install
1
| gem install padrino-lazy --pre |
Example
1
| $ padrino-lazy base --c config --b BaseModel --f "create_at:datetime is_active:boolean" |
now we have
lib/base_model.rb class BaseModel

Known issue
- VERY VERY alpha code !! (thanks to my pig/lazy side
)
- —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
)
