Django 找到模板但不渲染它并抛出一个空的 HTML 页面

Question

我在views.py有一个视图:

def simple_upload(request):
if request.method == 'POST' and request.FILES['myfile']:
myfile = request.FILES['myfile']
fs = FileSystemStorage()
filename = fs.save(myfile.name, myfile)
uploaded_file_url = fs.url(filename)
print(uploaded_file_url)
context = {
'uploaded_file_url': uploaded_file_url
}
return render(request, 'simple_upload.html', context)
return render(request, 'simple_upload.html')

然后，urls.py中的url:

urlpatterns = [
path('', views.project_index, name='project_index'),
path('<int:pk>/', views.project_detail, name='project_detail'),
path('upload/', views.simple_upload, name='upload')
]

当我点击路由/projects/upload时，我得到的不是一个表单，而是一个空页面。然而，simple_upload.html路由具有以下结构:

{% extends "base.html" %}
<h1>H</h1>
{% load static %}
{% block content %}
<form method="post" enctype="multipart/form-data">
{% csrf_token %}
<input type="file" name="myfile">
<button type="submit">Upload</button>
</form>
{% if uploaded_file_url %}
<p>File uploaded at: <a href="{{ uploaded_file_url }}">{{ uploaded_file_url }}</a></p>
{% endif %}
<p><a href="{% url 'home' %}">Return to home</a></p>
{% endblock %}

你可以看到，我得到一个空白页。

没有错误发生。

我找到了问题所在。你必须在模板中写{% block page_content %}而不是{% block content %}，因为在base.html中我有这一行:

{% block page_content %}{% endblock %}
