[英]Django. Simple FormView not saving
I'm kind of new to django generic FormView. 我是django通用FormView的新手。 I'm missing something obvious, the form renders correctly but it is not saving the data:
我遗漏了一些明显的东西,该表单可以正确呈现,但是它没有保存数据:
forms.py 表格
from perfiles.models import Perfil
class FormEditarPerfil(forms.ModelForm):
class Meta:
model = Perfil
fields = ('descripcion',)
views.py views.py
from django.views.generic.edit import FormView
from forms import FormEditarPerfil
class EditarPerfil(FormView):
template_name = "perfiles/editar_perfil.html"
form_class = FormEditarPerfil
def get_success_url(self):
url = reverse_lazy('perfiles:propio', kwargs={'username': self.request.user.username})
return url
You need to change the view's form_valid
method because the FormView
class does not call form.save()
and instead, just redirect the user to the success url. 您需要更改视图的
form_valid
方法,因为FormView
类不会调用form.save()
,而是将用户重定向到成功URL。
def form_valid(self, form):
form.save()
return super(EditarPerfil, self).form_valid(form)
Although, I would agree with @Filly's answer. 虽然,我同意@Filly的回答。 If you are creating a new object, use
CreateView
, otherwise, use UpdateView
. 如果要创建新对象,请使用
CreateView
,否则请使用UpdateView
。
You're on the right path! 您在正确的道路上! But
FormView
doesn't save your model, as the documentation indicates: 但是
FormView
不会保存您的模型,如文档所示:
A view that displays a form.
显示表单的视图。 On error, redisplays the form with validation errors;
错误时,重新显示带有验证错误的表格; on success, redirects to a new URL.
成功后,重定向到新的URL。
You are looking for UpdateView
. 您正在寻找
UpdateView
。 This way you don't need to create a separate form, just use the fields
attribute in your view: 这样,您无需创建单独的表单,只需在视图中使用
fields
属性即可:
from django.views.generic.edit import UpdateView
from perfiles.models import Perfil
class EditarPerfil(UpdateView):
template_name = "perfiles/editar_perfil.html"
model = Perfil
fields = ['descripcion']
def get_success_url(self):
url = reverse_lazy('perfiles:propio', kwargs={'username': self.request.user.username})
return url
