Question

我想添加一个新组，但是对于教师，他们必须从教师表中的列表中进行选择，因为它与组有关系。

表格：老师，小组
关系：教师 1到多组

models.py

class Teacher(models.Model):
    name = models.CharField(max_length=100)
    def __str__(self):
        return '%s' % (self.name)

class Group(models.Model):
    name = models.CharField(max_length=100)
    teacher = models.ForeignKey(Leraren, on_delete=models.CASCADE)
    def __str__(self):
        return '%s %s' % (self.name, self.teacher)

forms.py

class TeacherForm(forms.Form):
    name = forms.CharField(required=True, label='name', max_length=100)

class GroupForm(forms.Form):
    name = forms.CharField(required=True, label='name', max_length=100)
    teacher = # choose from list of teachers that are in the db Teachers #

Answer 1

只需将表单定义为ModelForm的{{1}}，即无需手动执行此操作

Group

如何添加新群组，但教师必须来自列表
