Instance Method Details

- (Object) path_for(path_params)

Given a hash of parameters, build a view path, if possible. Returns nil if no path can be built from the given params.

Examples:

# path can be built because all required params are present in the hash
view_path_builder = ViewPathBuilder.new(::Rails.application.routes)
view_path_builder.path_for({ :controller => 'posts', :action => 'show', :id => '54' })
# => "/post/54"
# path cannot be built because the params are missing a required element (:id)
view_path_builder.path_for({ :controller => 'posts', :action => 'delete' })
# => ActionController::UrlGenerationError: No route matches {:action=>"delete", :controller=>"posts"}
