How can I fetch the validation parameters from my models?
Example: I have a field with maxLength set to 20, and I want to
display an error message like "This field can only be 20 characters
long". Now, if I update the validation rule in my model to allow max
30 chars, I need to update my view as well:
In my view:
$form->input('name', array('type' => 'text', 'class' => 'input_text',
'error' => array('required' => 'Name is required', 'length' => 'This
field can only be 20 characters long')))
How can I avoid this? Can I fetch the rule in my view or controller in
some way?
