Live Front

Collection of useful helpers and workflows used at Live Typing.

Navigation link helper. Returns an li element with an 'active' class if the supplied controller(s) and/or action(s) are currently active. The content of the element is the value passed to the block. Initially was copied from GitLab project. Also it was added ability to specify params option to make link active when current path suits specified params.

options

The options hash used to determine if the element is "active" (default: {})

:controller - One or more controller names to check (optional).

:action - One or more action names to check (optional).

:path - A shorthand path, such as 'dashboard#index', to check (optional).

:params - One or more params to check. It also can be specified :_blank value to be able to specify either blank or non-blank param (optional).

:html_options - Extra options to be passed to the list element (optional).

block

An optional block that will become the contents of the returned li element.

When both :controller and :action are specified, BOTH must match in order to be marked as active. When only one is given, either can match.

Assuming we're on TreeController#show

# Controller matches, but action doesn't
nav_link(controller: [:tree, :refs], action: :edit) { "Hello" }
# => '<li>Hello</li>'

# Controller matches
nav_link(controller: [:tree, :refs]) { "Hello" }
# => '<li class="active">Hello</li>'

# Shorthand path
nav_link(path: 'tree#show') { "Hello" }
# => '<li class="active">Hello</li>'

# Supplying custom options for the list element
nav_link(controller: :tree, html_options: {class: 'home'}) { "Hello" }
# => '<li class="home active">Hello</li>'

# Supplying params options when `params[:state] # => 'archived'`
nav_link(path: 'tree#show', params: {state: 'archived'}) { "Hello" }
# => '<li class="home active">Hello</li>'

# Supplying params options when `params[:state] # => nil`
nav_link(path: 'tree#show', params: {state: 'archived'}) { "Hello" }
# => '<li class="home">Hello</li>'

# Supplying params options when `params[:state] # => nil`
nav_link(path: 'tree#show', params: {state: [:_blank, :active]}) { "Hello" }
# => '<li class="home active">Hello</li>'
