Inline SVG for Rails
# Put this method in your helper file to render inline SVG
def inline_svg(path)
file ="app/assets/images/#{path}", "rb")

This is extremely helpful sir, thank you very much.

Thanks for the snippet, it is good practice to close a file after you use it. I would therefore use the block form of File#open so that the file automatically get's closed after we read from it:

def inline_svg(path)"app/assets/images/#{path}", "rb") do |file|

Instead of hard coding the path to app/assets/images I suggest to let the asset pipeline manage the file location. Use Rails.application.assets.find_asset(path).to_s instead of reading the file directly.

Combining all this, I added this to my application helper:

  def inline_svg(path)
    raw Rails.application.assets.find_asset(path + '.svg').to_s

Rails.application.assets became nil when config.assets.compile = false on production. Does it matter?
