Has_many through question

Rails
1

hi there,
i thing i just have a logical problem.

i have following models.

class Area < ActiveRecord::Base
belongs_to :taskschedule
belongs_to :service
end

class Service < ActiveRecord::Base
has_many :taskschedules, :through => :areas
has_many :areas
end

class Taskschedule < ActiveRecord::Base
has_many :services, :through => :areas
has_many :areas
end

Following View

Taskschedule#new

New Taskschedule

<%= form_for @taskschedule, :url=>taskschedules_path do |f| %>

Area: <%= f.text_field :name %>

<% for service in Service.find(:all) %>

<%= check_box_tag :service_ids, service.id, @taskschedule.services.include?(service), :name => 'taskschedule[service_ids][]' -%> <%= service.name %>

<% end %>
<%= submit_tag “Submit” %>
<% end -%>

Taskschedule Controller
class TaskschedulesController < ApplicationController
def index
@taskschedules = Taskschedule.find(:all)
end

def new
@taskschedule = Taskschedule.new
@taskschedule.build.build_area
end

def create
@taskschedule = Taskschedule.new(params[:taskschedule])
if @taskschedule.save
redirect_to taskschedules_path
end
end

def edit
@taskschedule = Taskschedule.find(params[:id])
end

def update
@taskschedule = Taskschedule.find(params[:id])
if @taskschedule.update_attributes(params[:taskschedule])
redirect_to taskschedules_path
else
render ‘edit’
end
end

end

i have a text_field in areas that i want to be able to use in the
taskschedule#new view?
Thanks for any help.

The syntax of your question looks like a statement. What is your
question?
You are making whoever reads your question have to put thought into what
you
mean to ask.

i understand. i have 3 models. taskschedule, services and areas. each
taskschedule has many services through the model area.

when i add(create/update) services to taskschedule i want to enter
also some information to the model area. hope that makes sence.
thanks

So what are you stuck on? What problem are you looking to get an answer
for?

here is the taskschedule#new view

<%= form_for @taskschedule, :url=>taskschedules_path do |f| %>

Area: <%= f.text_field :name %>

<% for service in Service.find(:all) %>

<%= check_box_tag :service_ids, service.id, @taskschedule.services.include?(service), :name => 'taskschedule[service_ids][]' -%> <%= service.name %>

<% end %>
<%= submit_tag “Submit” %>
<% end -%>

as you can see i am assigning services to the taskschedule through the
model “area”. that works.
the problem is i have a textfield in the model area that i want to
fill over this view. i tried fields_for(:area) but get an error
message?
thanks,
ed

Ok, I think I understand what you are doing. I think what you should
look
into is using nested forms, meaning where you can have forms for
multiple
models and have rails handle all this automatically… if I am
understanding, once you post this you have some work to do on the
controller
side to save your data, right? There are two railscasts (at least) where
you
could start:
