我是 django 的新手，我正在尝试将带有外键的页面更新为主题。这是我的代码
models.py
class Subject(models.Model):
title = models.CharField(max_length = 200)
slug = models.SlugField(blank = False)
visible = models.BooleanField(default = True)
position = models.IntegerField()
date_published = models.DateTimeField(auto_now_add = True)
date_updated = models.DateTimeField(auto_now_add=False)
def __str__(self):
return self.title
class Page(models.Model):
subject = models.ForeignKey(Subject, on_delete= models.CASCADE)
title = models.CharField(max_length = 200)
slug = models.SlugField(blank = False)
description = models.TextField()
thumbs = models.ImageField(blank = True)
visible = models.BooleanField(default = True)
position = models.IntegerField()
date_published = models.DateTimeField(auto_now_add = True, auto_now=False)
date_updated = models.DateTimeField(auto_now_add=False, auto_now=True)
def __str__(self):
return self.title
urls.py
urlpatterns = [
path('dashboard/', views.dashboard, name='dashboard'),
re_path(r'^dashboard/edit/(?P<subject_slug>[w-]+)/(?P<slug>[w-]+)', views.edit_article, name='edit_page'),
]
views.py
def edit_article(request, subject_slug, slug):
subject = Subject.objects.get(slug = subject_slug)
article = subject.page_set.get(slug = slug)
form = ArticleForm(request.POST or None, instance = article)
if request == request.POST:
form = ArticleForm(request.POST, instance = article)
if form.is_valid():
c = form.save( commit = False)
c = subject
c.save()
return HttpResponseRedirect('/dashboard/')
context = {
'title' : article.title,
'article' : article,
'form':form
}
return render(request, 'dashboard/editarticle.html', context)
forms.py
from django import forms
from .models import Subject, Page, NewsFeed
class ArticleForm(forms.ModelForm):
class Meta:
model = Page
fields = ['title','slug','description','thumbs', 'visible','position']
文章.html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<title>Edit article</title>
<link rel="stylesheet" href="">
</head>
<body>
<h1>{{ title }}</h1>
<form method="POST" accept-charset="utf-8">{% csrf_token %}
{{ form.as_p }}
<input type ='submit' value='submit'/>
</form>
</body>
</html>
当我尝试保存表单时，视图不会重定向并且页面不会更新，你们能否启发我如何完成更新页面的任务。
提前致谢
你试过吗
def my_view(request):
...
return redirect('/some/url/')
参考 https://docs.djangoproject.com/en/2.1/topics/http/shortcuts/
尝试打印您从 slug 获得的文章，如果它正在获取文章，则只需分配
form = ArticleForm(instance = article)
现在，您将拥有一个具有先前值的初始化表单。
还有一个建议，尝试使用 django 类基础视图。仍然有任何疑问评论它。
