Stylesheets are not getting loaded while assets precompile

In assets.rb, I am using following code

def javascript_manifest_files(loc = '')
  Dir.chdir("#{Rails.root}/app/assets/javascripts/") do
    Dir["#{loc}*.js"]
  end
end


def stylesheet_manifest_files(loc = '')
  Dir.chdir("#{Rails.root}/app/assets/stylesheets/") do
    Dir["#{loc}*.css"]
  end
end


['', 'web/'].each do |loc|
  Rails.application.config.assets.precompile += javascript_manifest_files(loc) + stylesheet_manifest_files(loc)
end

I am very new to rails, found this solution for assets pipelining to work.

For JS I am getting all the required javascritp but for stylesheets I am not getting the styles.

To call the stylesheets I am using this command

<%= stylesheet_link_tag    'application', media: 'all' %>
<%= stylesheet_link_tag "#{params[:controller]}", media: 'all'  %>

When I am trying to open that page, geting following error. Someone please help me out to solve this issue.
