redmine settings tab project - ruby

Question

I want to put a new tab in the setting project on a Redmine plugin and I don't find how to do it.
I get the code of CCUL Project Managment plugin by ISITROL S.A.(www.isitrol.com) and replace de funcionlity with my funcionality, but I still can't change the name of the config_controller to my controller.
the helperpatch has this estructure:
require 'redmine'
require_dependency 'projects_helper'
module CCULProjectsHelperPatch
def self.included(base)
base.send(:include, ProjectsHelperMethodsCCUL)
base.class_eval do
unloadable
alias_method_chain :project_settings_tabs, :coste
end
end
end
module ProjectsHelperMethodsCCUL
def project_settings_tabs_with_coste
#tabs = project_settings_tabs_without_coste
#action = {:name => 'coste', :controller => 'coste_config', :action => :index, :partial => 'coste_config/index', :label => :tab_ccul}
Rails.logger.info "old_tabs: #{#tabs}"
Rails.logger.info "action: #{#action}"
#tabs << #action #if User.current.allowed_to?(action, #project)
#tabs
end
end
ProjectsHelper.send(:include, CCULProjectsHelperPatch) unless ProjectsHelper.included_modules.include? CCULProjectsHelperPatch
I've changed the name of the controller(and controller file's name), the view's folder and the name of the controller in the init file (I change pm_config to coste_pm)
This is the init file:
Rails.configuration.to_prepare do
require_dependency 'coste_project_helper_patch'
end
Redmine::Plugin.register :redmine_coste do
name 'Costes'
author 'Me'
description 'Plugin para calculo coste proyecto. Compatible con Redmine 2.3.x '
version '0.1.4'
project_module :coste do
permission :cost_manager, {:coste_config => [:index, :create], :coste_project => [:show]}
end
menu :project_menu, :coste, { :controller => 'coste_project', :action => 'show' }, :caption => :coste, :param => :project_id
menu :admin_menu, :coste, { :controller => 'coste_admin', :action => 'show' }, :caption => :coste
end
The error is "404 The page you were trying to acess doesn't exist or has been removed" when I try to access Settings of one project
I don't know what I need to change
I hope you can help me

Answer 1

I've found the problem, in the views templates of the settings the form had the old controller's name.
For who is looking for a way to put the setting project tab like me: I need take the database information in the view. Redmine doesn't call the controller when it creates the project settings tabs
And the code above is the basic to do it
