编辑：我有一个页面，显示某个视频游戏的帖子/文章。目前，我的查询返回的是来自该视频游戏的Post模型的帖子。但是，我不确定如何在同一页面上显示视频游戏说明和图像。加载页面时，{{game.cover.url}}，（（game.description}}和{{game.cover_display.url}}不会显示，因为我不确定如何也可以获取特定的游戏对象来自游戏模型。

{% for post in posts %}
{% with post.game.set.all|first as game %}
    <style>
    body {
        background-image: url("{{ game.cover_display.url }}");
        background-repeat: no-repeat;
        background-size: 100% 1000px;
        background-color: #171717;
}
</style>
    <div class="container margin-top-300 black">
      <div class="row justify-content-center">
        <div class="col-3 text-center">
            <img src="{{ game.cover.url }}">
        </div>
        <div class="col">
          <p>{{ game.description| safe }}</p>
        </div>
    </div>
    {% endwith %}
    <hr>
    <div class="row">
      <div class="col-4 article-column-height text-center">
           <a href="#"><img class="article-image-height" src="{{ post.article_image.url }}"></a>
      </div>
      <div class="col-8 article-column-height">
          <h2><a class="article-title" href="#">{{ post.article_title }}</a></h2>
      </div>
    </div>
    <hr>
  </div>

您正在使用ForeignKey。所以在循环中使用这样的

event

由于您已经按游戏进行过滤，因此只能将游戏添加到get_context_data（）方法中

def create
  event = Event.new(event_params)
  location = event.location.build() #or event.location.build(location_parms)
  location.save #will create record in events as well as location associated with the event
end

private
  def event_params
     #Whitelist only events attributes
     params.require(:event).permit(:name, :time, :organizer_id, attachments: [])
  end
