RSpec Request Warning - Rails 5.1 Upgrade - The Asset not present in asset pipeline

Question

I was in the process of upgrading a Rails 5.0.1 app to Rails 5.1 and encountered some deprecation warnings. I was able to resolve all but one.

I did some searching around and didn't find a definitive answer.

Background

This is an app that was just completed. I just updated the rails version to 5.1

I have some RSpec request specs. They test redirection in (Devise) login. This error shows up in those specs.

Controller specs run just fine. I see this warning in request specs concerning css, js, images etc.

I do have the dashboard.js in the asset pipeline. And there is an app/assets/javascripts/dashboard.coffee file.

# 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.

What I think is that the asset pipeline is been bypassed for specs.

Answer 1

You need to add dashboard.js in the assets.rb file to know 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 file name.
