I'll try renaming it, but I have used this pattern (and names) on many applications (this test app is an extraction from a working commercial application of mine, although that uses 4.1.8) and I am just trying to stub out multiple file uploads in this exercise.
I just re-built my environment -- re-installed rvm, ruby 2.1.3, bundler, rake, rails 4.2.1, and dropped a couple of gems that looked suspicious -- and started completely over with scaffold again. I am getting the identical problem. If it's just the name of the model, I will be frankly surprised, because each revision of Rails seems to remove reserved words, not add new ones. While I do that, here's the actual code -- if you can see anything suspicious, I'd be very grateful. class Asset < ActiveRecord::Base belongs_to :project has_attached_file :blob, :styles => { :large => "800x800", :medium => "400x400>", :small => "200x200>"} do_not_validate_attachment_file_type :blob end class Project < ActiveRecord::Base has_many :assets accepts_nested_attributes_for :assets, reject_if: :all_blank, allow_destroy: true end Rails.application.routes.draw do resources :projects resources :assets end The pattern I am trying to solve for is upload multiple assets in the project form (this works perfectly) and edit individual uploaded assets in their own assets/edit form. This latter part does not work. This is the form that is failing: <%= form_for(@asset) do |f| %> <% if @asset.errors.any? %> <div id="error_explanation"> <h2><%= pluralize(@asset.errors.count, "error") %> prohibited this asset from being saved:</h2> <ul> <% @asset.errors.full_messages.each do |message| %> <li><%= message %></li> <% end %> </ul> </div> <% end %> <div class="field"> <%= f.label :project_id %> <%= f.text_field :project_id %> </div> <div class="field"> <%= f.label :blob %> <%= f.file_field :blob %> </div> <div class="actions"> <%= f.submit %> </div> <% end %> While this one works just fine: <%= form_for(@project) do |f| %> <% if @project.errors.any? %> <div id="error_explanation"> <h2><%= pluralize(@project.errors.count, "error") %> prohibited this project from being saved:</h2> <ul> <% @project.errors.full_messages.each do |message| %> <li><%= message %></li> <% end %> </ul> </div> <% end %> <div class="field"> <%= f.label :name %> <%= f.text_field :name %> </div> <%= f.fields_for :assets do |a| %> <div class="field"> <%= a.label :blob %> <%= a.file_field :blob, multiple: true, name: "project[assets_attributes][][blob]" %> </div> <%- end -%> <div class="actions"> <%= f.submit %> </div> <% end %> Walter On May 3, 2015, at 10:13 AM, Colin Law <clan...@gmail.com> wrote: > On 3 May 2015 at 14:45, Walter Lee Davis <wa...@wdstudio.com> wrote: >> Started PATCH "/assets/1" for ::1 at 2015-05-02 15:32:49 -0400 > > Have you got a model called Asset?
