Question

In my form I use:
<%= hidden_field_tag :formtemplate, "newuser" %>

Based on this condition I want to validate in my model:

    validates_format_of :email, :supervisor, :with => /^([\w\.%\+\-]+)@([\w\-]+\.)+([\w]{2,})$/i, :message => "Adresse überprüfen.", :if => :newuser_formtemplate?

Here is newuser_formtemplate?

def newuser_formtemplate?
    newuser_formtemplate = "newuser"
    newuser_formtemplate == "newuser"
end

How would I have to change this to make it validate based on the hidden__field_tag?

Answer 1

Use attr_accessor in your model

attr_accessor :formtemplate

def newuser_formtemplate?
    newuser_formtemplate = self.formtemplate
    newuser_formtemplate == "newuser"
end

If you are using form_for in your view then use form object

<%= form.hidden_field :formtemplate, "newuser" %>
