Made changes in the code to debug and do not understand what's wrong. Hell, I'm on the debug production! This happened to you? To me several times. Library offers one of the ways to solve this problem.
Most everyone will understand from one picture:
This means that on the first tab we have development environment, on second stage, and third it's production(we don't need change this favicon).
It uses Tinycon - A small library for manipulating the favicon.
And one more option:
Icon will be gray on non production environment.
It you need this separately you can use Grayscale-Favicon - adopted for node package managers version.
Js usage for this task justified by the fact that more often than not have to worry about favicon caching, because favicon changes on the fly after it's loaded. However, if you do not like to use js for this problem, you may use alternative version of gem which uses https://github.com/rmagick/rmagick, follow to branch rmagick
Add this line to your application's Gemfile:
And then execute:
# adds initializer rails g rails_env_favicon:install
//= require rails_env_favicon
RailsEnvFavicon.setup do |config| # If true then favicon will be gray on non production env config.make_grayscale = false # or if make_grayscale = false then draw badge on favicon with this options: config.text_color = '#ffffff' config.background_color = '#549a2f' end
You can also configure the condition of changing favicon and badge label, just override
RailsEnvFavicon module methods. For example:
module RailsEnvFavicon def self.badge_label ENV['TEATRO'].present? ? 'T' : ::Rails.env.first.upcase end def self.applicable? !::Rails.env.production? || ENV['TEATRO'].present? end end
If you change a configuration to apply changes, you have to:
rm -rf tmp/cache/*in app directory, for assets cache cleaning.
