我有一个模型，其字段以 is_student 和 is_teacher Student 和 Teacher 形式调用
is_teacher = models.BooleanField('teacher status', default=False)
is_student = models.BooleanField('student status', default=False)
我想确保这个字段是:
- 始终由用户检查
True*必需
当前:TeacherApplications 模型中的 is_teacher
当未选中时 - 它会将 0 保存到表单并继续。 (不好)
当检查时给我这个错误:
ValueError at /register/teacher invalid literal for int() with base 10: ''
目前:is_student 在 StudentProfile 模型
- 当检查时给出这个错误
ValidationError at /register/ ["'on' value must be either True or False."]
- 当取消选中时，它会将 0 保存到表单并继续。 (再次，不好)
更新代码
以上错误消失了:每次我在检查 is_teacher/is_student 后尝试提交表单时都会出现新错误
IntegrityError at /register/ NOT NULL constraint failed: accounts_studentprofile.is_student
模型
class StudentProfile(models.Model):
user = models.OneToOneField('Accounts', related_name='student_profile')
# additional fields for students
AMEB_Ratings = models.PositiveIntegerField(default=0)
is_student = models.BooleanField('student status', default=False)
class TeacherApplications(models.Model):
user = models.OneToOneField('Accounts', related_name='teacher_profile')
# additional fields for teachers
instrument = models.TextField(max_length=500, blank=True)
skill = models.CharField(max_length=30, blank=True)
experience_in_years = models.PositiveIntegerField(blank=True)
is_teacher = models.BooleanField('teacher status', default=False)

表格
class StudentResistrationForm(forms.ModelForm):
class Meta:
model = StudentProfile
fields = (
'AMEB_Ratings',
'is_student',
)
def save(self, commit=True):
user = super(StudentResistrationForm, self).save(commit=False)
# user.first_name = self.cleaned_data['first_name']
# user.last_name = self.cleaned_data['last_name']
user.AMEB_Ratings = self.cleaned_data['AMEB_Ratings']
if commit:
user.save()
return user
class TeacherRegistrationForm(forms.ModelForm):
class Meta:
model = TeacherApplications
fields = (
'instrument',
'skill',
'experience_in_years',
'is_teacher',
)
class UserForm(forms.ModelForm):
class Meta:
model = get_user_model()
fields = ('username', 'email', 'password')
请您参考如下方法:
您可以将此字段添加到 StudentResistrationForm 和 TeacherRegistrationForm 并在 clean_fieldname 方法中为其添加自定义验证以使其成为必需字段:
StudentResistrationForm(ModelForm):
class Meta:
model = StudentRegistration
fields = (
'instrument',
'skill',
'experience_in_years',
'is_student',
)
def clean_is_student(self):
is_student = self.cleaned_data.get('is_student')
if not is_student:
raise forms.ValidationError('This field is required')
return is_student
此外，在 View 中，您可以使用表单创建 student 和 teacher 对象，而不是从 request.POST 获取原始数据:
new_user = User.objects.create_user(username=username, email=email, password=password)
teacher = form.save(commit=False)
teacher.user = new_user
teacher.save()
