Hello everybody. I have two models user and user_information. the User
has_one user_information and the UserInformation belongs_to user. Now I
need to make a form_for to create the user information for an user. So I go
to the following link: http://localhost:3000/users/1/user_informations/new
a fill the form, with the user_id, and the other fields. But I get the
following error:
Can''t mass-assign protected attributes: user_id
I think the error is in the user_information#new view, in the form_form. This is
the actual form
<%= form_for(@user_information) do |f| %>
<%= f.text_field :user %>
</div>
<div class="field">
<%= f.label :address %><br />
<%= f.text_field :address %>
</div>
<div class="field">
<%= f.label :phone %><br />
<%= f.text_field :phone %>
</div>
<div class="field">
<%= f.label :business %><br />
<%= f.check_box :business %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
I think the form_for should be something like <%=
form_for([@user_information, @user.user_information.bluild]) do |f| %> but it
doesn''t work. So I really really need your help, please.

Thanks Tomas.

You see the representation of the User model, which is composed of user attributes (like @user.id, etc.). My advice is to play with rails console to clarify your doubts -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

That User: 0x007fe37d33b5e0 you see is the object id for that User object that was created. Thats ruby''s ID for it. Your''s is contained inside that object. Don''t confuse 0x007fe37d33b5e0 with being the .id field inside that user. Two very different things. The .id field (@user.id) is the *database* assigned ID, while the 0x007fe37d33b5e0 is the *object* id for ruby to track the user object in memory. Hope this helps you understand the difference between the two. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
