RSpec Request Warning - Rails 5.1 Upgrade - Assets Missing in the Asset Pipeline

I was trying to upgrade my Rails 5.0.1 application to Rails 5.1 and came across some crash warnings. I was able to resolve everything but one.

I've searched a bit and haven't found a definitive answer.

Background

This is an application that has just been completed. I just updated my rails version to 5.1

I have an RSpec spec spec. They check the redirect to (Devise) login. This error appears in these specifications.

The controller specifications are working fine. I see this warning in BOM requests regarding css, js, images, etc.

I have dashboard.js

assets in my pipeline. And there is a file app/assets/javascripts/dashboard.coffee

.

# config/initializers/assets.rb
Rails.application.config.assets.precompile += %w[
  sites.js
  sites.css
  admin.js
  admin.css
  header.js
  dashboard.js
  dashboard.css
  setup.js
  setup.css
]

Warning

Here is the warning I see.

What i tried

  • pre-compiling assets manually didn't solve

I appreciate any advice on how to resolve this warning.

I think the asset pipeline has been bypassed for specs.

You need to add dashboard.js

to the file assets.rb

to find out rails that it needs to be precompiled.

#/config/initializers/assets.rb
Rails.application.config.assets.precompile += %w( dashboard.js )


Add this line, actually you just need to uncomment it and add the filename.

I had the same problem after I updated Rails to 5.1

I am assuming you store some of your assets in a folder ./public



You can move your assets from ./public

to folder ./app/assets

. Or just add a parameter skip_pipeline: true

like:

image_url("body-bg.gif", skip_pipeline: true)
