Django在反向重定向中使用新创建的对象 [英] Django using a newly create object in reverse redirect

问题描述

我正在尝试从新创建的项目对象中提取id，以便我可以将用户重定向到包含新项目的页面。现在我得到'ProjectAddForm'对象没有属性'id'。

I am trying to pull the id from the newly created project object so I can redirect the user to the page containing the new project. Right now I get "'ProjectAddForm' object has no attribute 'id'".

我已经在线阅读这应该工作，但由于某种原因，它不是。

I have read online that this should work but for some reason it's not.

if request.method == 'POST':
        form = ProjectAddForm(request.POST)
        if form.is_valid():
            form.save()
            return HttpResponseRedirect(reverse('project.views.detail', args=(form.id)))

Forms.py

class ProjectAddForm(forms.ModelForm):

    class Meta:
        model = Project

推荐答案

save 方法返回您的模型对象。请参考它，然后你将有你需要的反向重定向'id'。

The save method returns your model object. Grab a reference to it and then you will have the 'id' you need for your reverse redirect.

instance = form.save()
return HttpResponseRedirect(reverse('project.views.detail', instance.id))
