Question

大家好我想让我的HTML工作，但似乎我没有得到什么。

我的HTML如下：

// ==UserScript==
// @name        Timer Duck
// @namespace   Timer Duck
// @description Simple counter
// @include     https://duckduckgo.com/
// @version     1.0.0
// @grant       none
// ==/UserScript==


$(document).ready(function() {     

//Replace 'logo-wrap--home' with a visible counter formated '24(hours):60(minutes):60(seconds)'

});

我对链接项目的看法:(链接到网址：team_select）

    {% extends 'base.html' %}
{% block body %}
<div class="container">
  <div class="jumbotron">
    <h2>Welcome to your Project {{  project.name }} Detail page</h2>
  </div>

<!-- case 1 = if there is not team created or linked -->
  {% if project.team_id == None  %}
    <div class="invite-team">
      <div class="jumbotron">
        <div class="jumbo-text">
          <h3>Your project has been created, It is time to link a team or create a new for your project</h3>
        </div>
          <div class="jumbo-button">
            <a href="{% url 'website:team_select'%}" class="btn btn-default" role="button"><span class="glyphicon glyphicon-link"></span>   Link an existing team</a>
            <a href="{% url 'website:add_team' %}" class="btn btn-success" role="button"><span class="glyphicon glyphicon-plus"></span>   Create a new team</a>
          </div>
      </div>

<!-- case 2 = if there is a team created but no team members -->

{% elif project.team_id and project.team_id.members.count == 0 %}
<div class="invite-teammembers">
  <div class="jumbotron">
    <div class="jumbo-text">
      <h3>The team {{ project.team_id }} has beed created, we now need to add TeamMembers</h3>
    </div>
      <div class="jumbo-button">
        <a href="{% url 'registration:team_register3' %}" class="btn btn-success" role="button"><span class="glyphicon glyphicon-plus"></span>   Add Team Members</a>
      </div>
  </div>
</div>

<!-- any other situation -->
  {% else %}
    <h1>Youhouu</h1>

  {% endif %}
  </div>
</div>

{% endblock%}

我的HTML不会像它应该的那样渲染。我收到以下错误：

def TeamSelect(request):
    #import pdb; pdb.set_trace()
    if request.method == "POST":
        select_form = EditSelectTeam(request.user, request.POST)
        if select_form.is_valid():
            data = select_form.cleaned_data['team_choice']
            obj2 = Project.objects.filter(project_hr_admin=request.user)
            obj3 = obj2.latest('id')
            if obj3.team_id == None:
                obj3.team_id = data
                obj3.save()
                obj4 = obj3.team_id
                obj5 = obj4.members.all()

                for i in obj5:
                    current_site = get_current_site(request)
                    message = render_to_string('acc_join_email.html', {
                        'user': i.first_name,
                        'domain':current_site.domain,
                        })
                    mail_subject = 'You have been invited to SoftScores.com please LogIn to get access to the app'
                    to_email = i.email
                    email = EmailMessage(mail_subject, message, to=[to_email])
                    email.send()
                messages.success(request, 'test')
                return render(request,'project_details.html')
            else:
                print('this project has already a team')
        else:
            print('Non Valid form')

    else:
        select_form = EditSelectTeam(request.user)
    return render(request,'link_project.html',
                            {'select_form':select_form })

使用shell Could not parse the remainder: '()' from 'project.team_id.members.count()'的事情是真的但是project.team_id.members.count() == 0是project.team_id.members.count == 0。

我怎样才能让它发挥作用？

Answer 1

更改为：

{% if not project.team_id and project.team_id.members.count == 0 %}

和{% else %}代替{% else project.team_id.members.count() > 0 %}（无效）。

请注意()电话后count缺少。{/ p>

这就是你从HTML模板中调用count函数的方式。事实上，任何功能，不仅仅是这一个。请在behind the scenes中阅读点（.）运算符在Django模板中的工作原理。

在HTML中渲染django标记不起作用
