Django表單錯誤沒有顯示

Question

我已經查看了所有關於此的stackoverflow和互聯網，所以我只會顯示我的代碼。

views.py

def UserSell(request,username): 

theuser=User.objects.get(username=username) 
thegigform=GigForm() 
#if the user is submitting a form 
if request.method=='POST': 
    #bind form with form inputs and image 
    gigform=GigForm(request.POST,request.FILES) 
    if gigform.is_valid(): 
     gigform.title=gigform.cleaned_data['title'] 
     gigform.description=gigform.cleaned_data['description'] 
     gigform.more_info=gigform.cleaned_data['more_info'] 
     gigform.time_for_completion=gigform.cleaned_data['time_for_completion'] 
     gigform.gig_image=gigform.cleaned_data['gig_image'] 
     finalgigform=gigform.save(commit=False) 
     finalgigform.from_user=theuser 
     finalgigform.save() 
     return HttpResponseRedirect('done') 
thegigform=GigForm() 
context=RequestContext(request) 
return render_to_response('sell.html',{'theuser':theuser,'thegigform':thegigform},context_instance=context) 

模板

<form action="{% url sell user.username %}" method="post" enctype="multipart/form-data"> 
{% csrf_token %} 
<fieldset> 
    <legend><h2>Sell A Gig</h2></legend> 
    {% for f in thegigform %} 
    <div class="formWrapper"> 
     {{f.errors}} 
     {{f.label_tag}}: {{f}} 
     {{f.help_text}} 
    </div> 
    {% endfor %} 
</fieldset> 
<input type="submit" value="Sell Now!" /> 

此代碼似乎遵循普通的Django形式的協議，請告訴我爲什麼我的Django的模板犯規顯示錯誤。謝謝

它看起來像你缺少一個else塊。

如果gigform.valid（）返回false，則覆蓋變量「thegigform」。嘗試重新構造你的代碼，如下所示：

if request.method=='POST': 
    #bind form with form inputs and image 
    thegigform=GigForm(request.POST,request.FILES) 
    if thegigform.is_valid(): 
     thegigform.title=gigform.cleaned_data['title'] 
     thegigform.description=gigform.cleaned_data['description'] 
     thegigform.more_info=gigform.cleaned_data['more_info'] 
     thegigform.time_for_completion=gigform.cleaned_data['time_for_completion'] 
     thegigform.gig_image=gigform.cleaned_data['gig_image'] 
     finalgigform=gigform.save(commit=False) 
     finalgigform.from_user=theuser 
     finalgigform.save() 
     return HttpResponseRedirect('done') 
else: 
    thegigform=GigForm() 
context=RequestContext(request) 
return render_to_response('sell.html',{'theuser':theuser,'thegigform':thegigform},context_instance=context)
