在model中通過limit_choices_to過濾

limit_choices_to={
"pk": 3})

過濾出主鍵為3的用戶,但是這樣的問題是不能動彈的過濾出實時登錄的用戶,因此

在form中過濾

表

class ConsultRecord(models.Model):
    """
    跟進記錄表
    """
    customer = models.ForeignKey(
        ‘Customer‘,
        verbose_name="所咨詢客戶",
        on_delete=models.CASCADE)
    note = models.TextField(verbose_name="跟進內容...")
    status = models.CharField(
        "跟進狀態",
        max_length=8,
        choices=seek_status_choices,
        help_text="選擇客戶此時的狀態")
    consultant = models.ForeignKey(
        "UserInfo",
        verbose_name="跟進人",
        related_name=‘records‘,
        on_delete=models.CASCADE)
    date = models.DateTimeField("跟進日期", auto_now_add=True)
    delete_status = models.BooleanField(verbose_name=‘刪除狀態‘, default=False)

    def __str__(self):
        return str(self.customer) + str(self.consultant)
 

form

class ConsultRecordModelForm(forms.ModelForm):
    class Meta:
        model = ConsultRecord
        exclude = ["delete_status"]
        error_messages = {
            ‘customer‘: {‘required‘: ‘客戶名不能為空‘},
            ‘note‘: {‘required‘: ‘內容不能為空‘},
            ‘status‘: {‘required‘: ‘內容不能為空‘},
            ‘consultant‘: {‘required‘: ‘內容不能為空‘},
        }

    def __init__(self, request, edit_record, *args, **kwargs):
        super().__init__(*args, **kwargs)
        # 根據所實例的編輯記錄所屬客戶id進行過濾
        if edit_record:
            self.fields[‘customer‘].queryset = Customer.objects.filter(pk=edit_record)
            self.fields[‘consultant‘].queryset = UserInfo.objects.filter(pk=request.user.id)
        else:
            self.fields[‘customer‘].queryset = Customer.objects.filter(consultant=request.user.id)
            self.fields[‘consultant‘].queryset = UserInfo.objects.filter(pk=request.user.id)
        for field in self.fields.values():
            field.widget.attrs.update({‘class‘: ‘form-control‘})
 

實例化時傳入當前用戶的主鍵

class AddEditConsultRecords(View):

    # edit_id為空則是添加,不為空則為編輯
    def get(self, request, edit_id_record=None):
        edit_obj = ConsultRecord.objects.filter(pk=edit_id_record).first()
        edit_record = edit_obj.customer.pk  # 當前編輯的記錄所屬客戶的id
        form = ConsultRecordModelForm(request, edit_record, instance=edit_obj)  # 實例化轉給form
        return render(request, ‘consultrecord_add_edit.html‘, {‘form‘: form, "edit_obj": edit_obj})

    def post(self, request, edit_id_record=None):
        edit_obj = ConsultRecord.objects.filter(pk=edit_id_record).first()
        edit_record = edit_obj.customer.pk  # 當前編輯的記錄所屬客戶的id
        form = ConsultRecordModelForm(request, edit_record, request.POST, instance=edit_obj)  # 實例化轉給form
        if form.is_valid():
            form.save()
            return redirect(request.GET.get("next"))
        else:
            return render(request, ‘consultrecord_add_edit.html‘, {‘form‘: form, "edit_obj": edit_obj})
 

self.fields[‘A‘].queryset = B.objects.filter(條件)

A為B表中字段,filter中的條件
