Rails - Jun 2009 - Saving foreign key id's using form_for?

Greetings Ladies and Gents,

I am learning rails and am wondering about a best practice?  Currently
I am trying to save specific tasks for a project.  So tasks has a
belongs_to :project and project does has_many :tasks.  Well when
creating a new task I need to store to project_id in the tasks table.

Currently I can set the @tasks.project_id = @projects.id in the
TasksController create method or I can set the @task.project_id @project.id in
the TasksController new method and set a hidden_field
in the form_for for project_id for task.

Both ways seem unsexy, but its the best way I found.  Is there a
better way?  This is a nested resource also.

Current code:


<% form_for [:project, @task]  do |form| -%>

    <fieldset>
        <legend>Project Info</legend>
        <% fields_for :project do |p| %>
            <%= p.text_field :name, :disabled => :true %>
        <% end %>
    </fieldset>

    <fieldset>
        <legend>Task</legend>
        <%= render :partial => ''form'', :object =>
form %>
    </fieldset>
    <p>
        <%= submit_tag ''Create'' %>
    </p>

<% end -%>


Thanks.
