I have a decisions resource, which is nested under a groups resource. has_many and belongs_to have been defined in the models.
resources :groups do
resources :decisions
end
...and I have an edit form at this path:
/groups/:group_id/decisions/:id/edit(.:format)
I'm getting an error in my Rspec test:
Failure/Error: put :update, {:id => decision.to_param, :decision => valid_attributes, group_id: decision.group.id}, valid_session NoMethodError: undefined method `decision_url' for #DecisionsController:0x007ffeb23482e0>
And when I navigate to the form in my development environment, I get a similar error:
<%= link_to 'Edit', edit_group_decision_path(@group, @decision) %>
NoMethodError at /groups/6/decisions/5/edit
undefined method `decision_path' for #<#:0x007fd1ff569130>
I'm using the 'better_errors' gem, and it cites the first line of the form_for for the no method error:
<%= form_for(@decision) do |f| %>
I don't have 'decision_url' anywhere in my code. What am I missing? Shouldn't form_for know where to PUT the update? There's a valid path for it at:
/groups/:group_id/decisions/:id(.:format)
Here is the part of the log that looks most exciting:
Rendered decisions/_form.html.erb (6.5ms)

This is the decision_url call that it was complaining about:
if @decision.update(decision_params)
format.html { redirect_to @decision), notice: 'Decision was successfully updated.' }
Changing @decision to group_decision_path(@group, @decision) fixed it.
