我有两个模型，由外键连接 . 一个是内联formset . 由于某种原因，formset id被标识为数据库中的主键，并且每次提交表单时，基本上都会覆盖属于formset的表 . 保存时，如何忽略formset ID
models.py
class Student(models.Model):
first_name = models.CharField(max_length=40)
last_name = models.CharField(max_length=40)
email = models.EmailField()
class Courses(models.Model):
student = models.ForeignKey(Student)
course_name = models.CharField(max_length=40)
start_time = models.TimeField()
forms.py
class CoursesForm(forms.ModelForm):
class Meta:
model = Courses
exclude = ("student",)
class StudentForm(forms.ModelForm):
class Meta:
model = Student
fields = "__all__"
views.py ...
def post(self, request, *args, **kwargs):
sform = StudentForm(request.POST, instance=Student())
CourseSchedule = inlineformset_factory(Student, Courses, form=CoursesForm, can_delete=False, extra=0, min_num=1)
cforms = CourseSchedule(data=request.POST)
if sform.is_valid() and cforms.is_valid():
sform_obj = sform.save()
for cform in cforms.forms:
cform_obj = cform.save(commit=False)
cform_obj.student = sform_obj
cform_obj.save()
....

我想通了..我的formset数据在提交后仍然存在 . 我必须在basemodelformset中声明一个空的queryset .
