Python Can'；t将多对多字段的值插入django中的其他表中

我正在使用django 1.8。我试图在django中使用CreateView向数据库中插入一个值。我可以把数据插入数据库。问题是插入一个字段的值（多对多）。该字段用于插入另一个表。我将在下面简要解释

型号.py

 class Model1(models.Model):
    name = models.CharField()
    address = models.CharField()
    first_name = models.ManytoManyField(Model2)

 class Model2(models.Model):
    first_name = models.CharField() 

 class sampleForm(forms.ModelForm):
    name = forms.TextInput()
    address = forms.TextInput()
    first_name = forms.TextInput()

 class Create(CreateView):
    model = Model1
    form = sampleForm
    def form_valid(form):
      form.save()
      return super(Create,self).form_valid(form)

forms.py

 class Model1(models.Model):
    name = models.CharField()
    address = models.CharField()
    first_name = models.ManytoManyField(Model2)

 class Model2(models.Model):
    first_name = models.CharField() 

 class sampleForm(forms.ModelForm):
    name = forms.TextInput()
    address = forms.TextInput()
    first_name = forms.TextInput()

 class Create(CreateView):
    model = Model1
    form = sampleForm
    def form_valid(form):
      form.save()
      return super(Create,self).form_valid(form)

视图.py

 class Model1(models.Model):
    name = models.CharField()
    address = models.CharField()
    first_name = models.ManytoManyField(Model2)

 class Model2(models.Model):
    first_name = models.CharField() 

 class sampleForm(forms.ModelForm):
    name = forms.TextInput()
    address = forms.TextInput()
    first_name = forms.TextInput()

 class Create(CreateView):
    model = Model1
    form = sampleForm
    def form_valid(form):
      form.save()
      return super(Create,self).form_valid(form)

当我尝试向数据库中插入值时，名称和地址成功地插入到一个表中。“第一个名称”字段需要插入到另一个表中。但它没有插入。有人能帮我做这个吗。

在你的视图文件中，我想你可以用这个代码来做

 class Create(CreateView):
    model = Model1
    form = sampleForm
    def form_valid(form):
      form.save(commit=false)
      form.save()
      form.save_m2m()
      return super(Create,self).form_valid(form)

什么是

sampleForm

？sampleForm表示forms.py文件中的类名。为什么不显示它？问题可能与此有关。现在我已经发布了它…您的期望是错误的：多对多字段允许您关联表。它不会将插入表中的一行的部分副本创建到相关表中。请解释你想要达到的目标。
