Django。如何设置默认选项使用通用CreateView的

Question

型号：

class MyModel(model.Models) 
    status = models.ForeignKey(Statuses, on_delete=models.PROTECT, null=True, blank=True) 

浏览：

class MyViewCreate(CreateView): 
    model = MyModel 
    form_class = MyFrom 
    template_name = 'mymodel_form.html' 

形式：

class MyForm(ModelForm): 

    class Meta: 
     model = MyModel 
     fields = '__all__' 

我怎么能在该选项的形式设置缺省值或第一个值列表>

Answer 1

您可以使用initial像t他：

class MyViewCreate(CreateView): 
    model = MyModel 
    form_class = MyFrom 
    initial = {'status': '0'} 
    template_name = 'mymodel_form.html' 

或像这样：

class MyViewCreate(CreateView): 
    model = MyModel 
    form_class = MyFrom 
    template_name = 'mymodel_form.html' 

    def get_initial(self): 
     state = get_object_or_404(MyModel, some_field=some_value) 
     return { 
      'state':state, 
     } 

希望它能帮助！
