django - 无法在 Django 中保存表单(对象没有属性 'save')

Question

以下是我的表格:

class AdvancedSearchForm(forms.Form):
    valueofres = forms.ChoiceField (label="res", choices = ((0, 0),(2.2, 2.2)), required= False)

以下是我的看法:

def advancedsearch(request):
    if request.method == "POST":
        search = AdvancedSearchForm(request.POST, request.FILES)
        if search.is_valid():
            new_search = search.save(commit=False)

为什么我收到错误消息 'AdvancedSearchForm' object has no attribute 'save'？

Answer 1

save 默认仅适用于 ModelForm，不适用于 forms.Form

你需要做的就是这个。要么使用:

class AdvancedSearchForm(forms.ModelForm):
    valueofres = forms.ChoiceField (label="res", choices = ((0, 0),(2.2, 2.2)), required= False)
    class Meta:
        model=Search #or whatever object

或者:

def advancedsearch(request):
    if request.method == "POST":
        search_form = AdvancedSearchForm(request.POST, request.FILES)
        if search_form.is_valid():
            cd = search_form.cleaned_data
            search = #populate SearchObject()
            search.save()
