Hello everybody!
Suppose I create a model like the following:
class Email < ActiveRecord::Base
validates_presence_of :name
end
Is it possible to know the presence of “validates_presence_of” from a
view?
I imagine a helper in the view that automatically shows a “*” if the
field passed as a parameter is compulsory…
Thanks,
Silvano

I assume that you are trying to show the user the input field that has
been rejected? If so, the scaffold code generated will do this (it puts
a big box around the rejected field(s)). Generate a dummy project and a
scaffold and look how they do it there.

I think he wants to automatically show during the initial display of the
form which fields will be validated and required.

I can’t use scaffold (because I need more complex form) and I don’t like
the way
it shows errors: I want, for example, write error messages beside
fields.
I want to show if a field is required during the initial display of the
form:
more generally, I want have access from the view to the validation
schema of the
model. Is it possible?
Thanks,
