helper_method(name, *args, &block) click to toggle source

In order to not pollute our templates with helpers. prefixed everywhere we want to try to distinguish helpers that are almost always used as parameters to other methods such as path helpers and not add them as elements

# File lib/arbre/patches.rb, line 91
def helper_method(name, *args, &block)
  if name.match /_path$/
    helpers.send(name, *args, &block)
  elsif (const_get([name, 'engine'].join('/').classify) rescue nil)
    helpers.send(name, *args, &block)
  else
    current_arbre_element.add_child helpers.send(name, *args, &block)
  end
end
method_missing(name, *args, &block) click to toggle source

Implements the method lookup chain. When you call a method that doesn't exist, we:

1. Try to call the method on the current DOM context
2. Return an assigned variable of the same name
3. Call the method on the helper object
4. Call super
Calls superclass method

  elsif route_proxy = possible_route_proxy(name)
    route_proxy.send(name, *args, &block)
