Rails: Form for selecting an existing parent when creating new child records?

I have a has_many and belongs_to association set up between two models: Project and Task. I'd like to be able to create a form which enables me to create a new Task and assign an existing Project as a parent. For example, this form might have a pulldown for selecting from a list of existing projects. There are only a finite set of projects available in this application, so I've created Project records via a seeds.rb file. I do not need to make a form for creating new Projects. I believe I've achieved a solution by using a `collection_select` form helper tag in the new Task form. I'm pretty happy with how this works now, but just curious if there are other approaches to this problem. ``` #models/project.rb class Project < ActiveRecord::Base has_many :tasks, :dependent => :destroy end #models/task.rb class Task < ActiveRecord::Base belongs_to :project end #controllers/tasks_controller.rb class TasksController < ApplicationController def new @task = Task.new respond_to do |format| format.html # new.html.erb format.xml { render :xml => @task } end end def create @task = Task.new(params[:task]) respond_to do |format| if @task.save format.html { redirect_to(@task, :notice => 'Task was successfully created.') } format.xml { render :xml => @task, :status => :created, :location => @task } else format.html { render :action => "new" } format.xml { render :xml => @task.errors, :status => :unprocessable_entity } end end end end #views/new.html.erb <h1>New task</h1> <%= form_for(@task) do |f| %> <div class="field"> <%= f.label :name %><br /> <%= f.text_field :name %> </div> <div class="select"> <%= collection_select(:task, :project_id, Project.all, :id, :name) %> </div> <div class="actions"> <%= f.submit %> </div> <% end %> <%= link_to 'Back', tasks_path %> ```
