USAGE
|
|
form <model-class> <view-name> [scenario]
|
|
|
|
DESCRIPTION
|
|
This command generates a form view that can be used to collect inputs
|
|
for the specified model.
|
|
|
|
PARAMETERS
|
|
* model-class: required, model class. This can be either the name of
|
|
the model class (e.g. 'ContactForm') or the path alias of the model
|
|
class file (e.g. 'application.models.ContactForm'). The former can
|
|
be used only if the class can be autoloaded.
|
|
|
|
* view-name: required, the name of the view to be generated. This should
|
|
be the path alias of the view script (e.g. 'application.views.site.contact').
|
|
|
|
* scenario: optional, the name of the scenario in which the model is used
|
|
(e.g. 'update', 'login'). This determines which model attributes the
|
|
generated form view will be used to collect user inputs for. If this
|
|
is not provided, the scenario will be assumed to be '' (empty string).
|
|
|
|
EXAMPLES
|
|
* Generates the view script for the 'ContactForm' model:
|
|
form ContactForm application.views.site.contact
|
|
