django.views.generic中的CreateView類,是基於View的子類。CreateView可以簡單快速的創建表對象。
下面記錄小作代碼。
# polls/views.py
from django.views.generic import CreateView class QuestionCreate(CreateView): form_class = QuestionForm # 表類 template_name = 'polls/question_form.html' # 添加表對象的模板頁面 success_url = '/polls/thanks' # 成功添加表對象后 跳轉到的頁面 def form_invalid(self, form): # 定義表對象沒有添加失敗后跳轉到的頁面。 return HttpResponse("form is invalid.. this is just an HttpResponse object")
# polls/forms.py
from django.forms import ModelForm from polls.models import * class QuestionForm(ModelForm): class Meta: model = Question fields = '__all__'
# polls/models.py from django.db import models class Question(models.Model): question_text = models.CharField(max_length=200) pub_date = models.DateTimeField('date published') def __unicode__(self): return self.question_text + '\n' + str(self.pub_date)
# polls/question_form.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body> <form method="post"> {% csrf_token %} {{ form.as_p }} # {{ form.as_p }}會按QuestionForm中 Meta的fields的列表,列出需要添加的字段。 <input type="submit" value="Submit" /> </form> </body>
</html>
# polls/thanks.html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Thanks</title> </head> <body> Thanks! </body> </html>
# polls/urls.py from django.conf.urls import url from . import views urlpatterns = [ url(r'^questioncreate/$', views.QuestionCreate.as_view(), name='QuestionCreate'), ]
QuestionCreate繼承了CreateView, form_class指定了表單QuestionForm, QuestionForm指定了數據表Question, template_name指定了添加表對象的模板, success_url指定了添加表對象成功后跳轉的頁面,
