好吧，我的 django 站点中的发布按钮有问题.它没有执行其功能

Question

我使用django 3.0.3、python 3.8.5和Vs代码作为IDE。我正在单击"发布"按钮，但它不起作用。

---型号.py-

def publish(self):
self.published_data = timezone.now()
self.save()

---视图.py-

@login_required
def post_publish(request,pk):
post = get_object_or_404(Post,pk=pk)
post.publish()
return redirect('post_detail',pk=pk)

---urls.py-

path('post/<int:pk>/publish/',views.post_publish,name ='post_publish'),

--post_detail.html(模板(--

<a class="btn btn-primary" href="{% url 'post_publish' pk=post.pk %}">Publish</a>

--post_detail.html(完整模板(--

我是新来的，正在学习django框架，当我坚持做一些我不知道该做什么的事情时，感觉很糟糕，但我希望你们能帮助我。任何帮助都将不胜感激谢谢

Answer 1

我不认为它会那样工作，我认为像这样的工作会起作用：

urls.py

path('post/publish',views.post_publish,name ='post_publish'),

forms.py

from django import forms
from .models import Post
class PostForm(forms.ModelForm):
class Meta:
model = POST
fields = ['title', 'text', ...] # Your post model fields

views.py

from .forms import PostForm
@login_required
def post_publish(request):
if request.Method=='POST':
post_form = PostForm(request.POST)
if form.is_valid():
form.save()
return HttpResponseRedirect('/post_detail/'+str(pk))
post_form = PostForm()
return render(response, "publish.html", {"form": post_form})

templatepublish.html(当然可以添加其他html以呈现您喜欢的内容(

<form method="post">
{% csrf_token %}
{{form.as_p}}
<input type="submit" value="Publish">
</form>

PostForm将自动将您的Post模型转换为表单，当您"获取"publish.html时，此表单将是，当您单击发布按钮时，它将通过Post在同一url上提交表单数据。在我们的视图中，当它是POST时，将该请求解析为一个填充的表单，然后我们调用is_valid来清理数据并确保所有验证都得到满足。如果是，那么我们调用save函数，该函数将创建帖子并重定向到帖子详细信息页面。

在实现时，您仍然可能遇到一些导入错误或其他错误，但这是为了让您了解如何做到这一点。在实现此功能时，如果遇到一些错误，请告诉我。
