Breadcrumbs in Ruby on Rails

Question

I\'m slightly insecure about my breadcrumb solution. Names and links are defined in each controller action:

Home         


        

Answer 1

I made a gem named Gretel that is a Ruby on Rails plugin for creating breadcrumbs. The breadcrumbs are configured in a separate configuration file and selected in the view.

Example config/breadcrumbs.rb:

crumb :root do
  link "Home", root_path
end

crumb :projects do
  link "Projects", projects_path
end

crumb :project do |project|
  link project.name, project_path(project)
  parent :projects
end

crumb :project_issues do |project|
  link "Issues", project_issues_path(project)
  parent :project, project
end

crumb :issue do |issue|
  link issue.name, issue_path(issue)
  parent :project_issues, issue.project
end

In your view:

<% breadcrumb :issue, @issue %>

In your app/views/layouts/application.html.erb:

<%= breadcrumbs pretext: "You are here: " %>
