Sinatra and Kaminari without any views and without padrino-helpers gem

December 28, 2014 / Maciej Mensfeld / 3 Comments

If you have an app that doesn't have any views (for example it only responds with JSON) you still may want to use excellent Kaminari gem for paginating big data sets. Unfortunately even when you work only with JSON and you don't need any views helpers, you will still get this warning:

[!]You should install `padrino-helpers' gem if you want
to use kaminari's pagination helpers with Sinatra.
[!]Kaminari::Helpers::SinatraHelper does nothing now...

so to get rid of this, you have to add:

gem 'padrino-helpers'

to your Gemfile (even when you don't need it).

Luckily, there's a better way to do this. Add Kaminari to your Gemfile that way:

gem 'kaminari', require: %w( kaminari kaminari/hooks )

and then, either create a config/initializers/kaminari.rb or directly in your app.rb put this:

# Initialize the Kaminari gem
::Kaminari::Hooks.init

This will initialize Kaminari without requesting padrino-helpers.

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
