How to access checkbox value through a Controller Hook of Redmine

Question

I'm creating a controller hook of my issues_controller on Redmine. I followed this tutorial.

The question is I couldn't access the checkbox (That I created through a hook on view page) value to set my controller variable. Follow my code

_new_hook.html.erb

<div class="splitcontentright">
  <% @user = User.current %>
  <b><br><label for="mail_checker_issue"><%= check_box_tag "mail_checker_issue", 1, @user.pref.always_check_email %><%= l(:send_email) %></label></b>
</div>

issues_email_patch.rb

Rails.configuration.to_prepare do
  require_dependency 'issue'
  class Issue
    attr_accessor :mail_checker_issue
  end
end

controller_hook.rb

module Redmine_send_emails
  module Hooks
    class Issues_controller_hook < Redmine::Hook::ViewListener
      def controller_issues_new_before_save(context={})
        context[:issue].mail_checker_issue = context[:params][:mail_checker_issue]
      end
    end
  end
end

Until where I've checked the hook works well. I've debugged the application and it called correctly the controller_hook method, but I couldn't find the value of my checkbox within the params.

What's wrong? How to do it?

Answer 1

You don't see your checkbox value because you display it before labelled_form_for @issue so it does not belongs to the form.

You can place it here (there are 2 place for hook)

You can try to implement gem deface - I managed to use it in Redmine plugin.
