POST Django中FormView的方法？
POST method of FormView in Django?
编辑：只是在用户提交用户进行搜索时使用了一个新列表，尽管我不确定如何在我的 QueryUser class 中获取用户提交的内容（24 的 ID 只是一个测试，哦，我试着添加分页但把它撕掉了，因为当有人点击一个新页面时它会中断，会返回到下面发布的 Query.html，脆皮表格不是返回的数据）
class QueryUser(LoginRequiredMixin, FormView):
model = OnSiteLog
form_class = QueryForm
template_name = 'log/query.html'
success_url = '/'
def form_valid(self, form, *args, **kwargs):
user = form.cleaned_data.get('user')
def post(self, request, *args, **kwargs):
object_list = OnSiteLog.objects.filter(user_id=24).order_by('-checkIn')
super(QueryUser, self).post(request, *args, **kwargs)
page = request.GET.get('page', 1)
paginator = Paginator(object_list, 10) # 3 posts in each page
#make a map into the object list
try:
log_pages = paginator.page(page)
except PageNotAnInteger:
# If page is not an integer deliver the first page
log_pages = paginator.page(1)
except EmptyPage:
# If page is out of range deliver last page of results
log_pages = paginator.page(paginator.num_pages)
return render(request, 'log/query2.html', {'page':page, 'log':object_list, 'object_list':log_pages})
我想了解 Class 基于视图 在 Django 中的工作原理。我有 View 的下一个工作代码。我想在 FormView 的帮助下编写该代码。我的 `FormView 代码是否正确？我需要有人能够分析该代码并指出我的错误在哪里。如有任何帮助，我将不胜感激。
现在 get method 有效。问题是当我尝试 submit 形式时。表格不会消失。同时在控制台中我看到这个 url: "POST /url/ HTTP/1.1" 200 1891。在数据库中，我看到创建了新文章。如何用 post method 解决这个奇怪的问题？
带视图的 CBV：
class ArticleCreateView(FormView):
template_name = 'article/create_article.html'
form_class = ArticleForm
def post(self, request):
data = dict()
article_create_form = ArticleForm(request.POST, request.FILES)
if article_create_form.is_valid():
article_create_form.save()
data['form_is_valid'] = True
context = {
'articles': Article.objects.all()
}
data['html_articles'] = render_to_string(
'article/articles.html',
context
)
else:
data['form_is_valid'] = False
return JsonResponse(data)
def get(self, request):
data = dict()
article_create_form = ArticleForm()
context = {
'article_create_form': article_create_form
}
data['html_article_create_form'] = render_to_string(
'article/create_article.html',
context,
request=request
)
return JsonResponse(data)
带 FormView 的 CBV：
class ArticleCreateView(FormView):
template_name = 'article/create_article.html'
form_class = ArticleForm
form_dict = {
'Article_create_form': ArticleForm
}
def get(self, request):
data = dict()
context = {'article_create_form': ArticleForm()}
data['html_article_create_form'] = render_to_string(

return JsonResponse(data)
def form_valid(self, form):

self.object = form.save()
context = {'articles': Article.objects.all()}
data['html_articles'] = render_to_string(
'article/articles.html',
context
)
return JsonResponse(data)
编辑文章 FormView 代码：
class ArticleEditView(FormView):
template_name = 'article/edit_article.html'
form_class = ArticleForm
def get(self, request, pk):
data = dict()
context = {
'article': Article.objects.get(pk=pk),
'article_edit_form': ArticleForm(instance=Article.objects.get(pk=pk))
}
data['html_article_edit_form'] = render_to_string(
'article/edit_article.html', context, request=request
)
return JsonResponse(data)
def form_valid(self, form):
form.save()
data = dict()
data['form_is_valid'] = True
context = {'articles': Article.objects.all()}
data['html_articles'] = render_to_string('article/articles.html', context)
return JsonResponse(data)

当您的表单有效时，您发送回数据的 JsonResponse。您想要的是将用户重定向到包含一些消息的页面。
使用重定向！
https://docs.djangoproject.com/en/1.11/topics/http/shortcuts/#redirect
一些简单的东西，例如：
return redirect('form-thankyou')
当然还要添加一个 url 模式，其 url 名称为 form-thankyou
这个问题与您的观点没有任何关系。您发送 json 回复的事实意味着您在这里使用 Ajax；这意味着您已明确承担从浏览器更改页面的责任。
您的 Ajax 脚本需要在成功提交后执行某些操作。
您忘记将 form_is_valid 添加到 data
def form_valid(self, form):
data = dict()
self.object = form.save()
context = {'articles': Article.objects.all()}
data['html_articles'] = render_to_string(
'article/articles.html',
context
)
# NEXT LINE
data['form_is_valid'] = True
return JsonResponse(data)
