Failed generation of resource route for action

birisi (birisi) — Mon, 08 Feb 2010 21:30:02 GMT

// description of your code here



These methods test that the routes for resources defined in routes.rb are working as expected. Call them from your functional (controller) tests.



Add the following 3 methods to test/test_helper.rb (updated for Rails 1.2.5 which no longer uses semicolons as a separator for the edit action):



# Test for routes generated by map.resource (singular).

def assert_routing_for_resource(controller, skip=[], nesting=[])

  routes = [

    ["new",'/new',{},:get], ["create",'',{},:post],

    ["show",'',{},:get], ["edit",'/edit',{},:get],

    ["update",'',{},:put], ["destroy",'',{},:delete]

    ]

  check_resource_routing(controller, routes, skip, nesting)

end

# Test for routes generated by map.resources (plural).

def assert_routing_for_resources(controller, skip=[], nesting=[])

  routes = [

    ["index",'',{},:get], ["new",'/new',{},:get], ["create",'',{},:post],

    ["show",'/1',{:id=>'1'},:get], ["edit",'/1/edit',{:id=>'1'},:get],

    ["update",'/1',{:id=>'1'},:put], ["destroy",'/1',{:id=>'1'},:delete]

    ]

  check_resource_routing(controller, routes, skip, nesting)

end



# Check that the expected paths will be generated by a resource, and that

# the expected params will be generated by paths defined by a resource.

# routes is array of [action, url string after controller, extra params].

def check_resource_routing(controller, routes, skip=[], nesting=[])

  # set a prefix for nested resources

  prefix = nesting.join('s/1/')

  unless prefix.blank?

    prefix += "s/1/"

  end

  # Add params for nested resources.

  # For each 'nest', include a ":nest_id=>'1'" param.

  params = {}

  nesting.each do |param|

    params["#{param}_id".to_sym] = '1'

  end

  # Test each of the standard resource routes.

  routes.each do |pair|

    unless skip.include? pair[0]

      assert_generates("/#{prefix}#{controller}#{pair[1]}",

        {:controller=>controller,

        :action=>pair[0]}.merge(pair[2]).merge(params), {}, {},

        "Failed generation of resource route for action #{pair[0]} /#{prefix}#{controller}#{pair[1]}")

      assert_recognizes(

        {:controller=>controller,

          :action=>pair[0]}.merge(pair[2]).merge(params),

        {:path=>"/#{prefix}#{controller}#{pair[1]}", :method=>pair[3]},

        {}, "Failed to recognize resource route for path #{pair[3]}:/#{prefix}#{controller}#{pair[1]}")
