Question

我正在尝试保存一个包含多个字段的表单，例如多对一关系和MultiSelectCheckBox，如下所示：

型号：

class master(models.Model):
    id_numb=models.CharField(max_length=40,unique=True)
    gender=models.CharField(max_length=6)
    name=models.CharField(max_length=100)
    family_name=models.CharField(max_length=100)
    birth_date=models.DateField()
    nation_id=models.IntegerField(blank=True, null=True)
    id_code=models.IntegerField(blank=True, null=True)
    education=models.CharField(max_length=100, blank=True, null=True)
    job=models.CharField(max_length=100, blank=True, null=True)
    marriage_state=models.CharField(max_length=6, blank=True, null=True)
    comm=models.CharField(max_length=100, blank=True, null=True)
    mobile=models.IntegerField(blank=True, null=True)
    phone=models.IntegerField(blank=True, null=True)
    email=models.EmailField(blank=True, null=True)
    address=models.CharField(max_length=200, blank=True, null=True)

    def __str__(self):
        return (self.name +" "+ self.family_name)


class kelas(models.Model):
    master=models.ForeignKey(master,on_delete=models.CASCADE,blank=True, null=True)
    kelas_no=models.CharField(max_length=40,unique=True)
    start_date_c=models.DateField(blank=True,null=True)
    finish_date_c=models.DateField(blank=True,null=True)
    day_no=models.CharField(max_length=200,blank=True,null=True)

查看：

def courseregister(request):
    if request.method=="POST":
        form=CourseForm(request.POST)
        courses=kelas.objects.all()
        if form.is_valid():
            try:
                form.save()
                form=CourseForm()
                #return redirect("/show")
            except:
                pass

    else:
        form=CourseForm()
        courses=kelas.objects.all()
    return render(request, 'music/course.html', {'form':form,'courses':courses})

表格：

class CourseForm(forms.ModelForm):

days=(
    ('1','Sa'),
    ('2','Su'),
    ('3','Mo'),
    ('4','Tu'),
    ('5','We'),
    ('6','Th'),
    ('7','Fr'),
)
day_no=forms.ChoiceField(choices=days, widget=forms.CheckboxSelectMultiple())
class Meta:  
    model = kelas  
    fields = "__all__"     

def __init__(self, *args, **kwargs):
    super(CourseForm, self).__init__(*args, **kwargs)
    for field in iter(self.fields):
        self.fields[field].widget.attrs.update({
            'class': 'form-control myinputbox'
    })
    self.fields['day_no'].widget.attrs.update({'class': 'form-check-input'})

模型“ Kelas”中的数据未保存。我的错在哪里？我复查了很多次，但是我什么都没找到。预先感谢您的帮助。

如何使用MultiSelectCheckBox保存模型表单？
