Doesn't patch "User" model in a plugin (Redmine 2.0)

Added by Vladimir Pitin over 13 years ago

Sorry for my English :)

I have a plugin that works in "Redmine 1.3.0.stable.24228 (MySQL)"
This plugin extend a model "User". And it worked fine.

Now we have installed Redmine 2.0.0
I try rewrite my plugin, but extending model "User" call error "Expected /usr/share/srv-redmine/redmine-2.0/app/models/user.rb to define User"

This init.rb code:

Redmine::Plugin.register :advanced_roadmap do
  name 'Advanced Roadmap plugin'
  author 'Author name'
  description 'This is a plugin for Redmine'
  version '0.0.1'
  url 'http://example.com/path/to/plugin'
  author_url 'http://example.com/about'
end

#require 'user'

ActionDispatch::Callbacks.to_prepare do
    User.send(:include, AdvancedRoadmap::UserPatch)
end

If I add 

require 'user'

I have error:

ActionView::Template::Error (undefined method `association_class' for nil:NilClass):
    40:         <%= hidden_field_tag(controller.default_search_scope, 1, :id => nil) if controller.default_search_scope %>
    41:         <label for='q'>
    42:           <%= link_to l(:label_search), {:controller => 'search', :action => 'index', :id => @project}, :accesskey => accesskey(:search) %>:
    43:         </label>
    44:         <%= text_field_tag 'q', @question, :size => 20, :class => 'small', :accesskey => accesskey(:quick_search) %>
    45:         <% end %>

  app/controllers/projects_controller.rb:168:in `show'

This's content of file "lib/advanced_roadmap/user_patch.rb"

require_dependency "user" 

module AdvancedRoadmap
  module UserPatch
    def self.included(base)
        base.extend(ClassMethods)
        base.send(:include, InstanceMethods)        

      base.class_eval do 
      end

    end

    module ClassMethods   
    end

    module InstanceMethods
    end        

  end
end

It's my settings

I've been placing it within:

Rails.application.config.to_prepare do
end

Haven't noted any troubles

RE: Doesn't patch "User" model in a plugin (Redmine 2.0) - Added by Vladimir Pitin over 13 years ago

I tried this:

Rails.application.config.to_prepare do
end

But I've had same troubles.

Expected /usr/share/srv-redmine/redmine-2.0/app/models/user.rb to define User

Also, I created the deffect http://www.redmine.org/issues/11035

Other models is extending fine.

As commented on the defect:

This works:
lib/redmine_test/patches/user_patch.rb

require_dependency 'project'
require_dependency 'principal'
require_dependency 'user'
module RedmineTest
  module Patches
    module UserPatch
      def self.included(base)
        base.send(:extend, ClassMethods)
        base.send(:include, InstanceMethods)
        base.class_eval do
          unloadable
        end
      end

      module ClassMethods
        def echoTest
          STDOUT.print "echo Test\n" 
          STDOUT.flush
          nil
        end

      end

      module InstanceMethods
      end
    end
  end
end

ActionDispatch::Callbacks.to_prepare do
  User.send(:include, RedmineTest::Patches::UserPatch)
end

After which the User.echoTest method exists - you need to add require_dependency 'principal' before require_dependency 'user'

Hi

I tried patching the User with a method all_business_unit
def all_business_units
...
end

the patch is defined as :

require  'project'
require  'principal'
require 'user'

def self.included(base)
        require 'net/ldap'
        puts "loaded UserPatch" 
        base.send(:extend, ClassMethods)
        base.send(:include, InstanceMethods)
        base.class_eval do
          unloadable
        end
end

module ClassMethods
      def all_business_units
        #logic
      end
end
ActionDispatch::Callbacks.to_prepare do
    User.send(:include, RedminePlugin::Patches::UserPatch)
end

When the class gets loaded it displays the log statements however when I tried refer it from my controller like

User.all_business_units

it gives me the following error

NoMethodError (undefined method `all_business_units' for #<Class:0x560bf08>):
activerecord (3.2.13) lib/active_record/dynamic_matchers.rb:55:in `method_missing'

I am using redmine 2.3.2

Please suggest
