django - 在 ModelForm 中内联

Question

我想创建一个表格供用户填写。

该表单由一个公司模型和一个员工模型组成。

我希望用户以一种形式添加一家公司和他们想要的尽可能多的员工。

在 django admin 中，使用 StackedInline 很容易实现此功能，但我需要做什么才能在我的公共(public)表单中拥有相同的功能？

#models.py
class Company(models.Model):
    name = models.CharField()  

    def __unicode__(self):
        return self.name        


class Employee(models.Model):
    company = models.ForeignKey(Company)  
    first_name = models.CharField()  
    last_name = models.CharField()  


    def __unicode__(self):
        return self.first_name        

#admin.py
class EmployeeInline(admin.StackedInline):
    model = Employee


class CompanyAdmin(admin.ModelAdmin):

    inlines = [
        EmployeeInline,
    ]

    model = Company

admin.site.register(Company, CompanyAdmin)

#forms.py

class CompanyForm(ModelForm):
    class Meta:
        model = Company

class EmployeeForm(ModelForm):
    class Meta:
        model = Employee

#views.py
def companyform_view(request):

    if request.method == 'POST':

        form = CompanyForm(request.POST)

        if form.is_valid():

            f = CompanyForm(request.POST)
            f.save()

            return HttpResponseRedirect('/company/added/')

    else:
        form = CompanyForm()

    return render(request, 'form/formtemplate.html', {
        'form': form,
    })

Inline formsets是你需要的:

Inline formsets is a small abstraction layer on top of model formsets. These simplify the case of working with related objects via a foreign key.
