Suddenly getting 405 errors when using patch or put methods

[Walter Lee Davis]

I am working in a simple test application with Paperclip, and while I am able to upload in a #create, I am getting 405 errors from Webrick and Thin (in development) when trying to use the #update method.

I don't even get to the point in my console where I see the params -- it's happening before that. It's not a Rails error message, it's coming directly from the server.

I started in 4.2.1 and Ruby 2.1.3, and I have tried the entire matrix of 4.2.0 and 2.1.2 also without any change. I also tried both Chrome and Safari without any difference. I'm using Mac OS X 10.9.5 and rvm, if that makes any difference.

Thanks,

Walter

Assuming you run webrick in a terminal, what do you see in that
terminal when you submit the request?

Started PATCH "/assets/1" for ::1 at 2015-05-02 15:32:49 -0400

The browser shows plain text:

Method Not Allowed

and nothing else. It never hits ActiveRecord or even ActionController, as best I can see.

I can go back and reload and see the form page (and that is nothing remarkable -- I made it with the scaffold). I can view the index and use #create to make another such, but if I try to edit it, I get the error.

Have you got a model called Asset? I suspect that might cause
confusion with assets (js, css etc).
Is it only with assets that you get the problem?

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 %>

Thanks, Colin, for being able to state the obvious. Changing the model name made all the difference. Good to know, because I was starting to have some trust issues here...

I think the reason is that assets are served directly by the web
server, hence the request did not get to rails at all.

That doesn't jibe with what I am seeing in the rest of the application. I can GET them, and they go all the way through Rails, I can index them, and I can POST to the collection and create a new asset. It's just PATCH and PUT on the individual asset object that are affected.

I agree that changing the name is the expedient fix (although it's going to be hard to find another "neutral" name for "sub-project element that might be an image or a Flash banner ad or H264 movie"). I guess I'll call them Element, unless you have another suggestion.

Thanks again for your help,

Walter

Have you tried this running Thin in `trace` or `debug` mode? That
might be enlightening.

A simple test case to repro would be helpful, too.

I filed a bug report on rails/rails, and several people chipped in to help me locate the solution. Sprockets 3 is simultaneously greedy about the /assets route and silent about that fact. Adding this config statement:

Rails.application.config.assets.prefix = '/the-other-assets'

lets you get on with life when your model is named Asset.
