    <p>I've been working on a project with a has_many :through relationship between a Story and a Stack model, joined by Anthologies. I recently tweaked something that has broken the create method for new stories, but I'm not sure how to troubleshoot it. When I go to add a story, I get the following error:</p> <pre><code>**NoMethodError in StoriesController#create** undefined method `stack_id' for #&lt;Story:0x1035968a8&gt; </code></pre> <p>What's weird is that the create method makes no reference to 'stack_id'. In fact, it's pretty out of the box:</p> <pre><code>def create @story = Story.new(params[:story]) respond_to do |format| if @story.save flash[:notice] = 'Story was successfully created.' format.html { redirect_to(@story) } format.xml { render :xml =&gt; @story, :status =&gt; :created, :location =&gt; @story } else format.html { render :action =&gt; "new" } format.xml { render :xml =&gt; @story.errors, :status =&gt; :unprocessable_entity } end end end </code></pre> <p>I thought maybe it had something to do with the routes, as they support accessing stories both directly and nested in stacks. But I've tried a number of variations and nothing seems to make a difference.</p> <pre><code>map.resources :stories, :member =&gt; {:rate =&gt; :post} map.resources :anthologies map.resources :stacks, :has_many =&gt; :stories do |stack| stack.resources :stories end </code></pre> <p>I'm clearly not understanding something about how objects are getting saved here. Any ideas on how I can solve this problem? I'm completely lost on what to do next. I've added the console output below in case it's helpful.</p> <p>Thanks.</p> <pre><code>Processing StoriesController#create (for 127.0.0.1 at 2010-11-17 21:45:29) [POST] Parameters: {"commit"=&gt;"save", "story"=&gt;{"body"=&gt;"sgfhsfgh", "title"=&gt;"asdfa", "user_id"=&gt;"1", "summary"=&gt;"adfgdfhg"}, "action"=&gt;"create", "authenticity_token"=&gt;"1yws3Fs108kPSUS2W5SM1GFaiRqfiWhDbzDWstfoDCA=", "controller"=&gt;"stories"} User Load (0.3ms) SELECT "users".id FROM "users" WHERE ("users"."id" = 1) LIMIT 1 NoMethodError (undefined method `stack_id' for #&lt;Story:0x1035968a8&gt;): (eval):13:in `send' (eval):13:in `scope_condition' app/controllers/stories_controller.rb:58:in `create' app/controllers/stories_controller.rb:57:in `create' Rendered rescues/_trace (90.0ms) Rendered rescues/_request_and_response (0.3ms) Rendering rescues/layout (internal_server_error) </code></pre> <p>Adding Model code by request, but it's pretty generic has_many :through...</p> <pre><code>has_many :anthologies has_many :stories, :through =&gt; :anthologies </code></pre> <p>and</p> <pre><code>has_many :anthologies has_many :stacks, :through =&gt; :anthologies </code></pre>

    1. COCan you show us the model code? I'm guessing Story has `belongs_to :stack`

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.
