python之Django:返回呈现可哈希错误

我目前有以下代码:

url = "http://www.andes.ucmerced.edu/smap/backend/api/query\?    key\=9te21wWjfSZuq9aYqPqfwa3S8qBYAWP5zlav" 
query = "select data in (now -1440minutes, now) where Metadata/Location/Building='Facilities A' and Metadata/Location/Room ='130' and Metada/Haystack/Tags ~ 'temp'" 
r = requests.post(url, data=query).json() 
query1 = "select data in (now -1440minutes, now) where Metadata/Location/Building='Facilities A' and Metadata/Location/Room ='130' and Metada/Haystack/Tags ~ 'flow'" 
r1 = requests.post(url, data=query1).json() 
query2 = "select * where Metadata/Location/Building='Facilities A' and Metadata/Location/Room ='130'" 
r2 = requests.post(url, data=query2).json() 
query3 = "select data in (now -1440minutes, now) where Metadata/Location/Building='Facilities A' and Metadata/Location/Room ='130'" 
r3 = requests.post(url, data=query3).json() 
N_func = [] 
for datum in r3: 
    for datum1 in r2: 
        if datum['uuid'] == datum1['uuid']: 
            if len(datum['Readings']) == 0: 
                N_func.append(datum1) 
for datum in N_func: 
    r = datum['Path'].split('/') 
    datum['Path'] = r 
 
 
return render(request, 'polls/room_130.html', {'Temp': r}, {'Flow': r1}, {'N_Func': N_func},) 

我收到一条错误消息

请告诉我可能是什么原因。我已经尝试了一切。我试图将我正在呈现的对象更改为 JSON。但它仍然不起作用。

请您参考如下方法:

您应该为模板上下文使用单个字典:

return render(request, 'polls/room_130.html', {'Temp': r, 'Flow': r1, 'N_Func': N_func}) 

您当前的代码相当于:

return render(request, 'polls/room_130.html', {'Temp': r}, content_type={'Flow': r1}, status={'N_Func': N_func} 

这会导致错误，因为状态应该是一个整数(默认为 200)，而不是字典。
