python - 如何在html页面上显示模型字段 - Django

Question

我试图在用户个人资料页面上显示当前类(class)量，但无法显示。

这是我的模型.py:

class LessonCount(models.Model):
    user = models.OneToOneField(settings.AUTH_USER_MODEL)
    lesson_current_amount = models.PositiveIntegerField(default=0, verbose_name='Current Number of Lessons')

    def __unicode__(self):
        return str(self.user.username)

views.py:

@login_required
def user_profile(request):
    user = None
    lessoncount = LessonCount.objects.all()
    context = {
        'user': user,
        'lessoncount': lessoncount
    }
    return render(request, 'account/profile.html', context)

配置文件.html:

{% extends 'base.html' %}

{% block content %}

<h3 style="color: red;">{{ lessoncount.lesson_current_amount }}</h3>

<h3 style="color: red;">{{ request.user.username }}</h3>

{% endblock %}

提前致谢!

Answer 1

您需要遍历对象:

{% for lesson in lessoncount %}

<h3 style="color: red;">{{ lesson.lesson_current_amount }}</h3>

{% endfor %}
