Question

我有一个包含许多字段的Modelformset。 M2M字段呈现为ModelMultipleChoiceField。

填写所有表格后，整个程序运行正常。

简而言之，我收到的唯一用户输入来自表单集每种形式上的复选框。还有其他字段，但它们预先填充了用户数据。

我想保存选中复选框的表单，而忽略没有选择的表单。

我能够获取部分填写的表单以通过验证，因此所有表单都得以保存，但是我很难编写一个测试以放弃部分填写的表单（我们没有选择任何复选框的表单）。

Models.py

    customer_id = models.ForeignKey(CustomerDB, on_delete=models.CASCADE, default=None)
    services_manytomany = models.ManyToManyField(ContractorServices, blank=True)

class ContractorServices(models.Model):
    service_parent = models.ForeignKey(User, on_delete=models.CASCADE, default=None)
    service_name = models.CharField(max_length=150, null=True, blank=True)
    archive = models.BooleanField(default=False, null=True)

    def __str__(self):
        return self.service_name

forms.py

    services_manytomany = forms.ModelMultipleChoiceField(
        widget=forms.CheckboxSelectMultiple,
        queryset=ContractorServices.objects.all()
    )

    def __init__(self, user, *args, **kwargs):
        super(AddJob, self).__init__(*args, **kwargs)
        self.helper = FormHelper()
        self.helper.form_show_labels = False
        self.helper.form_show_errors = True
        self.helper.form_tag = False
        self.fields['services_manytomany'].required = False

        if user is not None:
            self.fields['services_manytomany'].queryset = ContractorServices.objects.filter(service_parent=user)

    class Meta:
        model = Jobs_DB
        fields = {'services_manytomany', 'frequency'}

相关的view.py代码


    formset = job_formset(queryset=Jobs_DB.objects.none(), form_kwargs={'user': request.user})

    if request.method == 'POST':
        form_a = AddJob(request.user, request.POST)
        formset = job_formset(request.POST, form_kwargs={'user': request.user})
        if formset.is_valid():
            instances = formset.save(commit=False)
            for instance in instances:
                instance.customer_id = CustomerDB.objects.get(pk=customer_id)
                instance.save()
            formset.save_m2m()

使用ManytoMany字段消除ModelFormSet中的部分填写的表单
