我有以下代码来处理一个简单的表单,我的观点是不发回http响应。
我无法弄清楚我的代码出了什么问题。
def novo_material(request):
current_page='material'
if request.method =='POST':
form = SystemInventoryUpdate(request.POST)
if form.is_valid():
name=form.cleaned_data['name']
qty=form.cleaned_data['qty']
unit=form.cleaned_data['unit']
t= NewMaterial(name=name,qty=qty,unit=unit)
t.save()
return HttpResponseRedirect(reverse('material'))
else:
form=NewMaterial()
return render(request,'novo_material.html',{'form':form})
引发此错误:
The view dashboard.views.novo_material didn't return an HttpResponse object. It returned None instead.
最佳答案
not form.is_valid()
时,您不返回任何HttpResponse
...
def novo_material(request):
current_page='material'
if request.method =='POST':
form = SystemInventoryUpdate(request.POST)
if form.is_valid():
name=form.cleaned_data['name']
''''''
t= NewMaterial(name=name,qty=qty,unit=unit)
t.save()
return HttpResponseRedirect(reverse('material'))
# No need to add `else` statement, the `return HttpResponseRedirect` above stops the `if`
# when form is invalid, it will jump to return render, with form validations generated by Django
else:
form=NewMaterial()
return render(request,'novo_material.html',{'form':form})
关于python - Django View未返回httpresponse,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/50109084/
