Hi everybody,
I apologize for my student''s english.
I got some problem with my Rails app, i got a collection_select who
aren''t submited & save in my database. After 2 days googling and
didn''t
find anything helpful i''am asking your help.
I had two tables: Crc and User: (I removed useless relation from others
tables)
User model:
class User < ActiveRecord::Base
has_many :crcs
accepts_nested_attributes_for :crcs
acts_as_authentic
def role_symbols
return ["#{self.role.name}".to_sym]
end
end
Crc model:
class Crc < ActiveRecord::Base
belongs_to :user
attr_accessible :user_id
validates_presence_of :name, :place
validates_uniqueness_of :name
end
My views: (I removed user field form except username)
<% form_for @user do |f| %>
<%= f.error_messages %>
<p>
<%= f.label :username %><br />
<%= f.text_field :username %>
</p>
</p>
<%= collection_select(:crc, :user_id, Crc.all, :id, :name) %>
</p>
<p><%= f.submit %></p>
<% end %>
My logs:
Processing UsersController#create (for 127.0.0.1 at 2010-07-26 12:20:29)
[POST]
Parameters: {"commit"=>"Save changes",
"authenticity_token"=>"6qJ/pJVcDVvNeaACnyOKRKT2R6EIA7TWVfvlMXxRMkk=",
"user"=>{"password_confirmation"=>"pass",
"role_id"=>"1",
"username"=>"usertest",
"password"=>"pass",
"email"=>"test-J0of1frlU80@public.gmane.org"},
"crc"=>{"user_id"=>"2"}}
For me that seems good.
i got an User_Create acion:
User Create (0.3ms) INSERT INTO `users` (`created_at`,
`crypted_password`, `updated_at`, `username`, `role_id`,
`password_salt`, `persistence_token`, `email`) VALUES(''2010-07-26
10:20:29'',
''b693ef04a548e3006ac8d81534717b46d7cb6146dd60e5f0e253d88356798431a5accabb135ee4727a68b9b9692e4245ab10ef9455fdbcfb44ffc88b5b402897'',
''2010-07-26 10:20:29'', ''usertest'', 1,
''SCgvhFqM0E9R7rkxXPWY'',
''26260bc8aa988fc3895af5b6cfcc5778b0872ce21aaa6924ac38f6c185293b457edb81d95a2ee3d5d7b78ea76a3229e6da68e6102c258861e857a769e784f2a5'',
''test-J0of1frlU80@public.gmane.org'')
I didn''t got Crc_Create action or any other Crc action. And my user_id
field still ''NULL'' on database.
Thanks for reading, I hope is clear.

You''re also not submitting name or place attributes for crc so the crc wouldn''t able to be saved anyway. Last of all you say you want tp create a new crc, but you''re asking the user to choose from a drop down populated with existing crcs, which doesn''t make sense to me Fred -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I used fields_for and it''s works but as you say, I create a new crc when I want to edit one. I put a partial on my users views: <% f.fields_for :crcs do |crc| %> </p> <%= render :partial => ''crcatt'', :locals => { :f => crc } %> </p> <% end %> and on "_crcatt.html.erb" I got: <%= f.collection_select( :user_id, @crcs, :id, :name) %> how can I edit the choosen crc ? I''am a ''little'' bit lost... I only got 4 month of rails experience and 1 years of OO language. Sorry for telling you my life ;). Thanks for your help.

According to what you posted above, users have multiple crcs. Fred -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Exactly users have multiple crcs, this is why I used nested attribute with child_link to add crcs to users. (I hope I''m understandable ..) In fact crcs are already created and had a ''NULL'' field on DB (user_id) that I want to edit on submitting with my collection.

If i were you (and had to do it this way) I''d probably just submit the id of the chosen crc separately and have a line somewhere that updates the user_id for that crc. Seems rather back to front though. Fred -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
