Ruby on Rails: RailsAdmin + HTTP Basic authentication

March 27, 2014 / Maciej Mensfeld / 0 Comments

RailsAdmin is an awesome gem when you want to build a not-so-much custom admin panel. Unfortunately it's not mentioned in documentation (or at least I couldn't find it) how to use it with HTTP Basic authentication. Here is an example of how to do this (put this in your config/initializers/rails_admin.rb file):

RailsAdmin.config do |config|
  config.authenticate_with do
    authenticate_or_request_with_http_basic do |username, password|
      username == 'user' &&
      password == 'password'
    end
  end

  # Other config stuff should go here
end

You should also use gem like SettingsLogic for storing credentials like this:

RailsAdmin.config do |config|
  config.authenticate_with do
    authenticate_or_request_with_http_basic do |username, password|
      username == System::Settings.admin.username &&
      password == System::Settings.admin.password
    end
  end

  # Other config stuff should go here
end

FriendlyId Ruby on Rails gem – update (refresh) slug after each record change

February 23, 2014 / Maciej Mensfeld / 0 Comments

If you want to have slugs that are refreshed (updated) each time you change corresponding field in your ActiveRecord models, put this at the end of your initializers/friendly_id.rb file:

module FriendlyId
  module Slugged
    def should_generate_new_friendly_id?
      return true if send(friendly_id_config.slug_column).nil? && !send(friendly_id_config.base).nil?

      change = :"#{friendly_id_config.base}_changed?"
      return true if respond_to?(change) && send(change)

      false
    end
  end
end

This will update slug each time related column (friendly_id_config.base) has changed. Keep in mind, that this method won't work if you use non-column slug method as a base for friendly ids, since it uses ActiveRecord::Dirty interface.
