我有一个Django应用程序。但是，我不能错过一段时间以来一直在努力的错误。
Exception Value: 'tuple' object has no attribute 'get'
Exception Location: /Library/Python/2.7/site-packages/django/middleware/clickjacking.py in process_response, line 30
这是django为我提供的追溯。
Traceback:
File "/Library/Python/2.7/site-packages/django/core/handlers/base.py" in get_response
201. response = middleware_method(request, response)

30. if response.get('X-Frame-Options', None) is not None:
我很难搞清楚这个错误发生的原因。我怎样才能找到代码中tuple的位置？

你在这里返回一个元组：
elif retailer_pk:
return (request, 'page-retailer-single.html', {
"products": products,
"sorting": filt["sorting"],
"filtering": filt["filtering"],
"retailer": retailer,
})
您是否忘记在那里添加render：
elif retailer_pk:
return render(request, 'page-retailer-single.html', {
"products": products,
"sorting": filt["sorting"],
"filtering": filt["filtering"],
"retailer": retailer,
})
答案 1 :(得分：3)
views.py
中return函数的末尾有一个逗号“，”
return render(request, 'index.html',{}), #incorrect
return render(request, 'index.html',{}) #correct
答案 2 :(得分：1)
即使采用逗号作为解决方案也很简单
原样
def home(request):
return render(request, 'index.html')
def hire(request):
return render(request, 'hire.html')
def handler400(request, exception):
return render(request, '400.html', locals())
def handler403(request, exception):
return render(request, '403.html', locals())
def handler404(request, exception):
return render(request, '404.html', locals())
def handler500(request, exception):
return render(request, '500.html', locals())
而不是 这个
def home(request):
return render(request, 'index.html'),
def hire(request):
return render(request, 'hire.html'),
def handler400(request, exception):
return render(request, '400.html', locals()),
def handler403(request, exception):
return render(request, '403.html', locals()),
def handler404(request, exception):
return render(request, '404.html', locals()),
def handler500(request, exception):
return render(request, '500.html', locals())
答案 3 :(得分：1)
始终确保在“返回”之后在视图函数中渲染
<块引用>就我而言，我没有添加 return render(request, app_name/index.html
我花了很多时间才找到这个错误，甚至堆栈溢出的一个答案都没有提到它，这就是我把它贴在这里的原因。
