django渲染模板问题

Question

I'm just built my django project but have some problem. I want to display title that is in Academy. When I run python manage.py runserver everything is okay but the title is not displayed. I don't know what the problem is.

class.html

{% extends "base.html" %}
{% block content %}
    <div>
        <div style="margin-top: 200px;">
        </div>
        {% for academy in academys %}
            <h3>{{ academy.title }}</h3>
        {% endfor %}
    </div>
{% endblock %}

urls.py

...
url(r'^academy/class', 'academy.views.class', name='class'),

views.py

from django.shortcuts import render, Http404
from .models import Academy

def class(request):
    template = 'academy/class.html'
    try:        
        academys = Academy.objects.all()
        context = {'academy': academys}

    except Academy.DoesNotExit:
        raise Http404

    if request.user.is_authenticated():
        return render(request, template, context)
    else:
        return HttpResponseRedirect("/account/login/")

models.py

...
class Academy(models.Model):
    title = models.CharField(max_length=50)

    def __unicode__(self):
        return self.title

Answer 1

Your context dictionary key is incorrect. Instead of

context = {'academy': academys} 

type

 context = {'academys': academys} 

Answer 2

您在上下文中通过的是“学院”，而不是“学院”

context={'academys ': academys}
