Really hoping someone on this forum can help me out - any help is greatly appreciated.
I have been through the Ryan B railcasts and tutorials on using a single form to update more than one model. They are all based on the concept of having Project model that has many Tasks. The application I am working on requires a third level of model added to the form so Projec has many Tasks and Task has many Task Details. I can display the form in the "new" action so that all fields show up and it appears right. However, I can not get the "create" to work, not sure if the problem is "create" in my controller, or the hash being created in my fields_for tag.
class Project < ActiveRecord::Base has_many :tasks
def task_attributes=(task_attributes) task_attributes.each do |attributes| tasks.build(attributes) end end end
class Task < ActiveRecord::Base has_many :task_details belongs_to :projects
def task_detail_attributes=(task_detail_attributes) task_detail_attributes.each do |attributes| task_details.build(attributes) end end
end
class TaskDetail < ActiveRecord::Base belongs_to :tasks end
class ProjectController < ApplicationController
def index @projects = Project.find(:all) end
def new @project = Project.new @project.tasks.build @task = Task.new @task.task_details.build end
def create @project = Project.new(params[:project]) @task = Task.new(params[:task]) params[:task].each_value { |task_detail| @task.task_details.build{task_detail} } if @project.save and @task.save flash[:notice] = "Successfully created project." render :action => 'index' else render :action => 'new' end end
end
<% form_for :project, :url => { :action => :create } do |f| %> <p> Name: <%= f.text_field :name %> Date: <%= f.date_select(:date) %> </p> <% for task in @project.tasks %> <% fields_for "project[task_attributes]", task do |task_form| %> <p> Name: <%= task_form.text_field :name %> Description: <%= task_form.text_area :description %> Fixed Task: <%= task_form.check_box :fixed_flg %> </p> <% end %>
<% for task_detail in @project.tasks %> <% fields_for "task[task_detail_attributes]", task_detail do | detail_form| %> <p> Sub Task: <%= detail_form.text_field :sub_task %> Assigned: <%= detail_form.check_box :assigned_flg %> </p> <% end %> <% end %> <% end %>
<p> <%= submit_tag "Create Project" %> </p> <% end %>
