这是我的模特.我想捕获"地址"栏中的数据，然后将其显示在表格的下拉菜单中，我正在使用该表格填充另一个表格，而不是再次键入邮箱地址.

Create your models here.

class Employee(models.Model):
    address = models.EmailField(max_length=100,null=True)
    first_name = models.CharField(max_length=50,null=True)
    sec_name = models.CharField(max_length=50,null=True)       
    department = models.CharField(max_length= 50,null=True)
    company = models.CharField(max_length= 50,null=True)
    date_created = models.DateTimeField(default=timezone.now)
    date_updated = models.DateTimeField(auto_now=True)

def __str__(self):
    return self.first_name + ' - ' + self.department

这是我用来向第二个模型添加数据的表单

class SaveCategory(forms.ModelForm):
    name = forms.CharField(max_length="250")
    description = forms.Textarea()
    status = forms.ChoiceField(choices=[('1','Active'),('2','Inactive')])

class Meta:
    model = Category
    fields = ('name','status')

def clean_name(self):
    id = self.instance.id if self.instance.id else 0
    name = self.cleaned_data['name']
    # print(int(id) > 0)

    try:
        if int(id) > 0:
            category = Category.objects.exclude(id=id).get(name = name)
        else:
            category = Category.objects.get(name = name)
    except:
        return name

    raise forms.ValidationError(f"{name} Category Already Exists.")

这就是我要向其中添加数据的模型.

class Category(models.Model):
    name = models.CharField(max_length=250)
    status = models.CharField(max_length=2, choices=(('1','Active'),('2','Inactive')), default=1)
    date_created = models.DateTimeField(default=timezone.now)
    date_updated = models.DateTimeField(auto_now=True)

    def __str__(self):
        return self.name
