嗨#1人,Django的:基於類視圖模型對象「有沒有屬性‘_meta’」
我與基於類的意見和試驗現場工作,我跟着documentation設置類爲本次。 對於一個項目站點(基於下面的項目模型),我只想爲下面的簡單項目模型創建一個快速CRUD應用程序。
models.py
class Project(models.Manager):
name = models.CharField(_('Name of the Project'), max_length = 100,)
slug = models.SlugField(max_length=100,)
...
views.py
from django.views.generic.edit import CreateView, UpdateView, DeleteView
from django.core.urlresolvers import reverse_lazy
from project.models import Project
class ProjectCreate(CreateView):
model = Project
class ProjectUpdate(UpdateView):
model = Project
現在當我加載\project\add
,這應該叫ProjectCreate
類,我得到以下錯誤: 類型對象'Project'沒有屬性'_meta'
我不明白爲什麼。模型類通常不需要元信息。在其他基於類的項目中,我沒有遇到這個問題。
謝謝您的建議!

是否還有其他一些缺失?因爲我按照您的建議做了同樣的事情,所以不會刪除屬性錯誤。 – tilaprimera
應該導入什麼模型的'models.Model'?有很多選擇,但似乎我的自定義模型不適合其中任何一個。 – KasparTr
