    <p>I'm trying to pass a project id from a session in a hidden field on a task form, so that when the task is created, it has the id of the project that it is assigned to. I've done this before fine, and have even tried copying over the code that I used from when it worked, but changing names and I'm getting errors no matter what I do - if anyone could help point out where I'm going wrong, it would be much appreciated, thanks!</p> <p>The error I'm getting with this configuration is: "unknown attribute: project_id"</p> <p>View Code (tasks/_form):</p> <pre><code>&lt;%= form_for(@task) do |f| %&gt; &lt;div class="field"&gt; &lt;%= f.hidden_field :project_id, :value =&gt; session[:project_id] %&gt; &lt;/div&gt; ... &lt;% end %&gt; </code></pre> <p>Model Code (task):</p> <pre><code>attr_accessible :project_id belongs_to :project </code></pre> <p>Controller code (tasks_controller):</p> <pre><code>def new @task = Task.new @project_id = session[:project_id] respond_to do |format| format.html # new.html.erb format.json { render json: @task } end end def create project_id = session[:project_id] @task = Task.new(params[:task]) respond_to do |format| if @task.save format.html { redirect_to @task, notice: 'Task was successfully created.' } format.json { render json: @task, status: :created, location: @task } else format.html { render action: "new" } format.json { render json: @task.errors, status: :unprocessable_entity } end end end </code></pre> <p>Here's the application trace - it is pointing to line 46, which in my code is the '@task = Task.new(params[:task])' line in the create action...?</p> <pre><code>app/controllers/tasks_controller.rb:46:in `new' app/controllers/tasks_controller.rb:46:in `create' </code></pre>

    1. COA stack trace would be nice, so people would know where this error comes from. I'm guessing it's from `@task = Task.new(params[:task])` but it would be nice to if you could confirm that.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
