Hello all,

Having a bit of a problem with validates\_associated. I assume I’m  
missing something out but basically got these two models -

class Seller \< User

has\_one :profile, :foreign\_key =\> ‘user\_id’, :dependent =\> :destroy  
has\_many :properties

validates\_associated :profile

end

class Profile \< ActiveRecord::Base

belongs\_to :user  
validates\_presence\_of :title, :forename, :surname, :address\_a

end

My form looks like

## Register as seller

\<%= error\_messages\_for :user %\>  
\<% form\_for :user do |f| -%\>

Login  
 \<%= f.text\_field :login %\>

Email  
 \<%= f.text\_field :email %\>

Password  
 \<%= f.password\_field :password %\>

Confirm Password  
 \<%= f.password\_field :password\_confirmation %\>

\<% fields\_for :profile do |p| %\>

Title  
 Mrs Mr Miss Ms Dr

Forename  
 \<%= p.text\_field :forename %\>

Surname  
 \<%= p.text\_field :surname %\>

Address  
 \<%= p.text\_field :address\_a %\>

Address  
 \<%= p.text\_field :address\_b %\>

Town/City  
 \<%= p.text\_field :town %\>

County  
 \<%= county\_options\_for\_select %\>

Postcode  
 \<%= p.text\_field :postcode %\>

Subscribe to mailing list  
 \<%= p.check\_box :mailing\_list %\>

\<% end %\>

\<%= submit\_tag 'Sign up' %\>

\<% end -%\>

Basically when I submit the form with the missing fields required by  
the Profile model, the form submits anyway.

Any suggestions?

Thanks in advance,

Alastair

validates\_presence\_of :profile

Hi Jeremy,

That seems to result in “Profile can’t be blank” whether all the  
fields are filled or not. Any ideas?

Thanks!

Alastair

Thanks again, missed that bit! It was late. All working now.

Cheers,

Assign the profile to the user before validating the user.

Alastair, could you post your fixed code? I’m not sure I follow what  
you changed to make it work.

Thanks,  
Ben

Hi Ben,

It wasn’t my models that were incorrect, I had missed some code in  
the controller that linked the user with it’s user profile.

Basically this: @profile = @user.profile = Profile.new(params  
[:profile]) fixed the problem. It wasn’t the validates, it was that  
the user and it’s profile were unrelated.

Cheers,

Alastair
