rails check if a form was completely filled out

I have information in my rails view that I only want to show up if the user has entered all personal details in the database, such as name, firstname, street and city. I could now do this:

if user.name && user.firstname && user.street && user.street
# show stuff
end

but I don't think that is very elegant and "the rails way". Is there an easier and smarter way to do this?

in model:

ALL_REQUIRED_FIELDS = %w(name surname address email)

def filled_required_fields?
  ALL_REQUIRED_FIELDS.all? { |field| self.attribute_present? field }
end

in your controller:

@user.filled_required_fields?

will return true if all fields filled and false if not.

looks very gracefully :)

You can use required in your html form tags and validations in Model Class. Also follow links: http://guides.rubyonrails.org/active_record_validations.html http://www.w3schools.com/tags/att_input_required.asp

In your model

class User < ActiveRecord::Base
  def has_required_fields?
    self.name && self.first_name && self.address && ....
  end
end

And in your controller

 if user.has_required_fields?
   # do whatever you want
 end

The "rails way" would be thin controller, fat model. So, in your case, you'd want to create a method inside your User model and use it in your controller afterwards.

User model:

def incomplete?
  name.blank? or firstname.blank? or street.blank?
end

User controller:

unless user.incomplete?
  # Show stuff
end
