如何为Django ModelForm创建子窗体

我不知道要添加多少子表单要添加多少子表单是个问题。我希望在单击按钮时创建要保存的子窗体，并希望选择要在主窗体中使用的已保存数据

我的模型

class Teste(models.Model):

   name = models.CharField(max_length=255)
   parent_institution_name = models.CharField(max_length=255)
   laboratory_departament = models.CharField(max_length=255, null=True, 
   blank=True, verbose_name="Laboratório")
   cep = models.CharField(max_length=255, verbose_name="Cep")
   cnpj = models.CharField(max_length=255, verbose_name="CNPJ")
   lat = models.FloatField(blank=True, null=True)
   lng = models.FloatField(blank=True, null=True)
   institution_name = models.CharField(max_length=255, null=False, 
   verbose_name="Nome da instituição")
   parent_institution_name = models.CharField(max_length=255, blank=True, 
   null=True, verbose_name="Nome da instituição vinculada")
   coordinator = models.CharField(max_length=255, verbose_name="Pessoa 
   Responsavel")
   email = models.CharField(max_length=255, verbose_name="E-mail")
   website = models.CharField(max_length=255, blank=True, null=True, 
   verbose_name="Website")
   rad_operating_time = models.IntegerField(verbose_name="Tempo de atuação 
   ")
   research_line = models.ManyToManyField('researcher.ResearchLines')

我的模型 类TestFormforms.ModelForm： 类元：

        model = Test
        exclude = ('employee_number', ' revenues', 'filter_grade', 'grade', ' 
        knowledge_grade',
    'application_grade', 'ie_grade', ' ia_grade', 'final_grade', 'inactive', 'last_coordinator_access', ' hr_count',
    'hr_returned', ' match_hr_count', 'general_grade', 'lat', 'lng'
    'tokens', 'iso_certification', 'other_certification', 'researchers', 'thematic_network',
    )


    widgets ={
        'name':forms.TextInput(attrs={
            'class':'form-control',
            'placeholder': 'Nome da UBC'
        }),
        'parent_institution_name': forms.TextInput(attrs={
            'class':'form-control',
            'placeholder':'Nome da Instituição à qual a UBC é vinculada'
        }),
        'laboratory_departament': forms.TextInput(attrs={
            'class':'form-control',
            'placeholder':'Laboratório/Departamento'
        }),
        'cep': forms.TextInput(attrs={
            'class':'form-control',
            'placeholder':'CEP'
        }),
        'cnpj': forms.TextInput(attrs={
            'class':'form-control',
            'placeholder':'CNPJ'
        }),
        'institution_name': forms.TextInput(attrs={
            'class':'form-control',
            'placeholder':'Nome da instituição'
        }),
        'coordinator': forms.TextInput(attrs={
            'class':'form-control',
            'placeholder':'Pessoa Responsável'

        }),
        'email': forms.TextInput(attrs={
            'class':'form-control',
            'placeholder':'E-mail'
        }),
        'website': forms.TextInput(attrs={
            'class':'form-control',
            'placeholder':'Website'
        }),
        'rad_operating_time': forms.TextInput(attrs={
            'class':'form-control',
            'placeholder':'Tempo de atuação em projetos de P&D+I'
        }),
        'phone': forms.TextInput(attrs={
            'class':'form-control',
            'placeholder': 'Telefone'
        }),
        'partner_category': forms.RadioSelect(),

        'main_product':forms.CheckboxSelectMultiple( attrs={
            'type':'checkbox'
        }),        
    }

我的表单看起来如何，最后一个输入显示了子表单添加数据的位置

---

这里是一个我使用内联表单集的示例，它实质上是将两个表单合并到一个显示的表单中。表单集是服务表单，冲头表单，我的意图是冲头是表单中的表单

VIEWS.PY是最有影响力的部分
