rails_navigation

Simplify matching of Rails routes. You are unhappy with the link_to_if helper?

Then check out this gem! You can now match controllers and actions as they are defined in your routes.rb.

Installation

Add this line to your application's Gemfile:

gem 'rails_navigation'

And then execute:

$ bundle

Works like current_page? Example:

matches_page?('controller#action')

with multiple conditions:

matches_page?(['controller#action', 'other_controller#action'])

Uses matches_page? and creates a link and a li element

Source code, if you want to customize it:

def nav_to(name, path, conditions = nil)
 content_tag :li, link_to(name, path), class: ('active' if matches_page?(conditions))
end

You have a webseite full of books and want to show an edit button on the books#show page.

matches_page?('books#show')

Matching controllers:

{ controller: "pages" } becomes 'pages'

Matching controllers and actions:

{ controller: "pages", action: "new" } becomes 'pages#new'

Matching controllers, actions and params:

{ controller: "pages", action: "show", params: { id: 'homepage' } } becomes 'pages#new?id=homepage'

Or even simpler (id is the default):

{ controller: "pages", action: "show", params: { id: 'homepage' } } becomes 'pages#new?homepage'
