ruby-on-rails - Redmine:用于添加新闻的自定义过滤器字段

Question

我想在 Redmine 的“添加新闻”页面添加一个自定义过滤器字段，这样当我添加新新闻时，我可以选择电子邮件应该发送到的用户组。

该字段本身是一个 Redmine 用户组列表，每个用户至少分配给其中一个。

有人做过吗？任何建议将不胜感激

我找到了与该问题相关的 3 个文件:

• /app/controller/news_controller.rb
• /app/models/news.rb
• /app/views/news/_form.html.erb

Environment:  Redmine version                          2.2.1.stable.11156  Ruby version                             1.8.7 (x86_64-linux)  Rails version                            3.2.11  Environment                              production  Database adapter                         MySQLRedmine plugins:  no plugin installed

So far I've done only 1 modification in Redmine, which sends added news to all registered users.File: /app/modelsmailer.rb

Overview:

EDIT: Following your advice I moved mailer function to the controller:

  def create
    @news = News.new(:project => @project, :author => User.current)
    @news.safe_attributes = params[:news]
    @news.save_attachments(params[:attachments])

    if @news.save
      #news_added(@news)
      if params[:group]
        mail :to => GroupsUser.find(params[:group][:ids]).joins(:users).select("users.mail").compact,
            :subject => "[#{@news.project.name}] #{l(:label_news)}: #{@news.title}"
      else
        render :new
      end
    end
  end

但我收到错误:NameError (uninitialized constant NewsController::GroupsUser): pointing to line

mail :to => GroupsUser.find

Answer 1

新闻 Controller .rb:

def new
  @news = News.new
  @groups = GroupsUser.all
end

新闻/_form.html.erb:

<%= label_tag :group_ids "Groups"
<%= collection_select :group, :ids, @groups, :id, :name, {}, multiple: true %>

编辑:

我将不得不对您的 Controller 的外观进行一些猜测，但我会给您一些接近的东西。根据您提供的邮件程序功能，我假设在保存 News 之后从 create Controller 中调用了它。之后我会调用邮件功能。像这样:

def create
  news = News.new(params[:news]
  if news.save
    news_added(news)
    send_mail_to_groups(params[:group][:ids]) if params[:group]
    redirect_to ...
  else
    render :new
  end
end

邮寄部分应该从news_added中移除

def news_added(news)
  redmine_headers 'Project' => news.project.identifier
  @author = news.author
  message_id news
  @news = news
  @news_url = url_for(:controller => 'news', :action => 'show', :id => news)
end

支持它自己的新例程:

send_mail_to_users_by_group_ids(group_ids)
    # Woo: Sent to all users, despite their email settings
    mail :to => GroupsUser.find(group_ids).joins(:users).select("users.mail").compact,
      :subject => "[#{@news.project.name}] #{l(:label_news)}: #{@news.title}"
end

您可能想要添加一个 where 子句以仅包含活跃用户。

我认为这是对的。我正在做这件事，所以那里可能有一两个错别字或错误。希望它能为您指明正确的方向。
