Hello.
Stuck on some HABTM stuff here... I''m new to rails and I''m
kinda lost
on this topic.
FYI This is all within the context of a working restful_authentication
and role_requirement setup. I am simply adding a radio button pair to
my new user form. When submitted, I need the appropriate tables
updated. As is, only the user table will update. The join table will
not. I have tried a handful of different things both for the
fields_for params and inside the controller''s create action with no
luck yet. Here''s what I have below.
Thanks for the input!
THE CLASSES:
class User < ActiveRecord::Base
has_and_belongs_to_many :roles
end
class Role < ActiveRecord::Base
has_and_belongs_to_many :users
end
THE CONTROLLER: Edited for brevity...
class UsersController < ApplicationController
def new
@user = User.new
end
def create
logout_keeping_session!
username = params[:user][:first_name]
username += params[:user][:last_name]
params[:user][:login] = username
# Create a random password.
random_p = User.generate_pass 8
params[:user][:password] = random_p
@user = User.new(params[:user])
success = @user && @user.save
if success && @user.errors.empty?
redirect_back_or_default(''/'')
flash[:notice] = "Thanks for signing up!"
else
flash[:error] = "Too bad sucka!"
render :action => ''new''
end
end
end
THE FORM: new.html.erb
<% form_for @user do |f| -%>
<p><%= label_tag ''first_name'' %><br/>
<%= f.text_field :first_name %></p>
<p><%= label_tag ''last_name'' %><br/>
<%= f.text_field :last_name %></p>
<p><%= label_tag ''email'' %><br/>
<%= f.text_field :email %></p>
<% fields_for :role, @roles do |ff| %>
<p>Select account type:<br>
<%= label_tag :name_user, "User" %>
<%= ff.radio_button :name, "user" %>
<%= label_tag :name_admin, "Admin" %>
<%= ff.radio_button :name, "admin" %>
</p>
<% end %>
<p><%= submit_tag ''Sign up'' %></p>
<% end -%>
Here''s a sample of how the params are going out:
Processing UsersController#create (for 127.0.0.1 at 2009-03-16
17:59:38) [POST]
Parameters:

If i understood correctly, you want the role to be added to the user
upon creation, but its not.
here is the code that would do it
def create
logout_keeping_session!
params[:user][:login] = params[:user][:first_name] + params[:user]
[:last_name]
# Create a random password.
params[:user][:password] = User.generate_pass 8
@user = User.new(params[:user], :roles => [ Role.new(params
[:role]) ] # in an array
# success = @user && @user.save # user will always have
something, therefore this line is redundant
if @user.save
redirect_back_or_default(''/'')
flash[:notice] = "Thanks for signing up!"
else
flash[:error] = "Too bad sucka!"
render :action => ''new''
end
end
hope it helps

When I implement this line: @user = User.new(params[:user], :role => [ Role.new(params[:role]) ]) I get this argument error. ArgumentError in UsersController#create wrong number of arguments (2 for 1) Any thoughts?

Thanks for the input. That does prevent the error but it does not actually update the roles_users join table that is a part of the habtm association between User and Role. I just tried this code within Create and it seems to work:... @user = User.new(params[:user]) @user.roles.build(params[:role]) However, I have a question still. I was assuming that the Roles table would not actually have a new record added when saving an habtm assoc. model. I assumed only the join table and the Users table would be updated. Otherwise it seems as though I would have a lot of redundant data in my Roles table. Am I misunderstanding something here?

Just another question that may help me better understand habtm workings... Would it be true that in order to create a fully functional habtm record that both models using the habtm assoc. need to be updated and saved? Or is it possible to do having a fully working relationship by saving only one of the two?

I mean, you are telling Rails to build a role: @user.roles.build(params[:role]) If only the users table and the roles_users table were updated the role would not exist. Remember, the join table only contains two columns: role_id and user_id. In order to register an HABTM in the join table there must be *one* role and *one* user. If it still doesn''t make sense to you, I recommend that read the documentation for HABTM associations: http://api.rubyonrails.org/classes/ActiveRecord/Associations/ClassMethods.html#M001792 -- Cheers, David Knorr http://twitter.com/rubyguy --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Thanks for the input David. I''ll explain myself a bit more here, maybe you could help me further? I am building an interface so an admin can create new users and assign them to have either a "user" or "admin" role using restful_authentication and role_requiremnt. I have a roles table that I have manually placed two records under the Name column for both "user" and "admin". These are the only two user roles expected. It seems that if each time I add a new user and I add a new record under the Name column of the roles table as well that I am going to have a lot of redundant data in roles. IE there could be twenty entries under Name roles that say "user" and then X amount more that say "admin". It would seem that I only need one record for each in roles to adhere to some semblance of DB normalcy ideals.?.?. Should only the user table and the join table be updated to somehow map to the correct existing roles Name record? IE "user" or "admin". And if so, whats the code to do that? Thanks a ton for the help here!

IE "user" or "admin". > And if so, whats the code to do that?If you would like to associate multiple users with the same two roles in your database, you would have to do it like this: @user.roles << Role.find_by_name(params[:role_name]) Keep in mind, that this is going to allow the user to have multiple roles. The #<< method is going to add another role to the collection of roles, the user already has. The params[:role_name] is simply the name of the role, you''ld like the user to have, for example "admin". -- Cheers, David Knorr http://twitter.com/rubyguy --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
