Formidable takes care about your forms. You write a class and
- Get logic out of your views.
- Get logic out of your controllers (presenter pattern).
- Validations will work even if the form can’t be mapped directly to the models.
- You can unit test your forms directly without touching the template layer at all.
- Validations
- Coercions
Forms contains quite complex logic which definitely shouldn’t be in your views
JS validation plugin
class Posts
def new
@form ||= PostForm.new
@form.attributes[:method] = "POST"
end
def edit
@form ||= PostForm.new
@form.attributes[:method] = "PUT"
end
def create(raw_data)
@form = PostForm.new(nil, raw_data)
if @form.save
redirect url(:posts)
else
self.new
end
end
def update(id, raw_data)
@form = PostForm.new(nil, raw_data)
if @form.update(id)
redirect url(:posts)
else
self.edit
end
end
end
