How do I display SVG image in Rails?

Question

I have a svg image on /app/asssets/images/symbols.svg with this as contents.

Answer 1

Displaying SVGs (scalable vector graphics) in a Rails app

Specifically include the SVG filetype in asset compilation

production.rb 

  config.assets.precompile += %w( '.svg' )  

  # Must include to get inline SVGs to work in deploy
  config.assets.css_compressor = :sass

Create a helper to display the SVG

myhelper.rb

def show_svg(path)
  File.open("app/assets/images/#{path}", "rb") do |file|
    raw file.read
  end
end

Invoke the SVG processing helper in your view

<%= show_svg('symbols.svg') %>

From your question I'm not 100% clear about your implementation, but these steps should get you to the point where your SVG image is visible. Once you have the SVG visible, you can apply CSS.
