Django：使用 inlineformset_factory 更新和创建数据记录

Question

有人可以帮我吗我正在尝试使用“inlineformset_factory”我实际上让它工作但不是更新记录它只是复制记录

这是我的view.py

def resume(request):
user = request.user.personaldetails

form1 = personalDetailsForm(instance=user)

workExpFormSet = inlineformset_factory(
    personalDetails, employmentHistory, form=employmentHistoryForm, extra=3, max_num=3)

formset = workExpFormSet(instance=user)

if request.method == 'POST':
    form1 = personalDetailsForm(request.POST, request.FILES, instance=user)
    formset = workExpFormSet(request.POST, instance=user)
    if form1.is_valid():
        form1.save()
    if formset.is_valid():
        formset.save()
    else:
        print(formset.errors)
    # print(formset)

return render(request, 'main/Client/resume.html', {'form1': form1, 'formset': formset})

我的models.py

class personalDetailsForm(ModelForm):
profile_image = forms.ImageField(label="", widget=forms.FileInput(
    attrs={'type': 'file', 'id': 'mediaFile'}))
jobTitle = forms.CharField(label="", required=False, widget=forms.TextInput(
    attrs={'type': 'text', 'class': 'form-control', 'id': 'jobTitle'}))
fname = forms.CharField(label="", required=False, widget=forms.TextInput(
    attrs={'type': 'text', 'class': 'form-control', 'id': 'fname'}))
lname = forms.CharField(label="", required=False, widget=forms.TextInput(
    attrs={'type': 'text', 'class': 'form-control', 'id': 'lname'}))
email = forms.EmailField(label="", required=False, widget=forms.TextInput(
    attrs={'type': 'email', 'class': 'form-control', 'id': 'email'}))
phone = forms.CharField(label="", required=False, widget=forms.TextInput(
    attrs={'type': 'text', 'class': 'form-control', 'id': 'phone'}))
country = forms.CharField(label="", required=False, widget=forms.TextInput(
    attrs={'type': 'text', 'class': 'form-control', 'id': 'country'}))
city = forms.CharField(label="", required=False, widget=forms.TextInput(
    attrs={'type': 'text', 'class': 'form-control', 'id': 'city'}))
address = forms.CharField(label="", required=False, widget=forms.TextInput(
    attrs={'type': 'text', 'class': 'form-control', 'id': 'address'}))
birthplace = forms.CharField(label="", required=False, widget=forms.TextInput(
    attrs={'type': 'text', 'class': 'form-control', 'id': 'pdate'}))
birthdate = forms.CharField(label="", required=False, widget=forms.TextInput(
    attrs={'type': 'text', 'class': 'form-control', 'id': 'bdate'}))
nationality = forms.CharField(label="", required=False, widget=forms.TextInput(
    attrs={'type': 'text', 'class': 'form-control', 'id': 'national'}))
profSummary = forms.CharField(label="", required=False, widget=forms.Textarea(
    attrs={'type': 'text', 'class': 'form-control', 'id': 'summaryEditor'}))
postalcode = forms.CharField(label="", required=False, widget=forms.TextInput(
    attrs={'type': 'text', 'class': 'form-control', 'id': 'postal'}))

class Meta:
    model = personalDetails
    fields = '__all__'
    exclude = ['accounts']

class employmentHistoryForm(ModelForm):
JobTitle = forms.CharField(label="", required=False, widget=forms.TextInput(
    attrs={'type': 'text', 'class': 'form-control jobTitle', 'name': 'jobTitle'}))
start_date = forms.CharField(label="", required=False, widget=forms.TextInput(
    attrs={'type': 'text', 'class': 'form-control startDate', 'name': 'start_date'}))
end_date = forms.CharField(label="", required=False, widget=forms.TextInput(
    attrs={'type': 'text', 'class': 'form-control endDate', 'name': 'end_date'}))
employer = forms.CharField(label="", required=False, widget=forms.TextInput(
    attrs={'type': 'text', 'class': 'form-control employerName', 'name': 'employer'}))
city = forms.CharField(label="", required=False, widget=forms.TextInput(
    attrs={'type': 'text', 'class': 'form-control employerCity', 'name': 'city'}))
description = forms.CharField(label="", required=False, widget=forms.Textarea(
    attrs={'type': 'text', 'class': 'form-control employeeEditor', 'style': 'height: 100px;', 'name': 'description'}))

class Meta:
    model = employmentHistory
    fields = '__all__'
    exclude = ['personal']

最后是用于自定义模型的表格

class employmentHistoryForm(ModelForm):
JobTitle = forms.CharField(label="", required=False, widget=forms.TextInput(
    attrs={'type': 'text', 'class': 'form-control jobTitle', 'name': 'jobTitle'}))
start_date = forms.CharField(label="", required=False, widget=forms.TextInput(
    attrs={'type': 'text', 'class': 'form-control startDate', 'name': 'start_date'}))
end_date = forms.CharField(label="", required=False, widget=forms.TextInput(
    attrs={'type': 'text', 'class': 'form-control endDate', 'name': 'end_date'}))
employer = forms.CharField(label="", required=False, widget=forms.TextInput(
    attrs={'type': 'text', 'class': 'form-control employerName', 'name': 'employer'}))
city = forms.CharField(label="", required=False, widget=forms.TextInput(
    attrs={'type': 'text', 'class': 'form-control employerCity', 'name': 'city'}))
description = forms.CharField(label="", required=False, widget=forms.Textarea(
    attrs={'type': 'text', 'class': 'form-control employeeEditor', 'style': 'height: 100px;', 'name': 'description'}))

class Meta:
    model = employmentHistory
    fields = '__all__'
    exclude = ['personal']

每当我 enter/save 我的表单数据时，它都会创建一条记录并添加另一条记录，该记录与前一条记录中的数据相同，它只是乘以最后输入的数据...但是每当我试图改变最后一条输出的数据有错误：

[{'id': ['This field is required.']}, {'id': ['This field is required.']}, {'id': ['This field is required.']}]

Answer 1

这是因为您没有在您的模板中包含 id 字段，或者可能实施错误（因为您没有包含您的模板代码，我假设这就是问题所在，很可能是这种情况）。由于 Forms 没有找到与 post 数据关联的任何 ID，因此它假定这是一个创建请求而不是编辑请求。
