扩展用户模型Django，IntegrityError

Question

我试图扩展User模型以创建Profile模型。以下代码成功显示了一个表单，其中指定了location和bio的附加字段。但是，当我提交表格时，只有原始的username,first_name,last_name,email和password字段存储在数据库http://127.0.0.1:8000/admin，我的自定义字段都没有存储在我添加到管理员的配置文件部分。我也得到了以下错误：

Answer 1

你不能做注册和轮廓POST在time.because您的个人资料模式是1to1场它属于User这意味着现有的用户可以创建一个用户profile.So最初用户应该不仅仅是他们可以创建自己的注册账号创建个人资料。

Answer 2

你必须设置的关系手动那么你的观点应该是这样的：

if form.is_valid() and profile_form.is_valid(): 
     user_object = form.save() 
     a = profile_form.save(commit=False) 
     a.user = user_object 
     a.save() 
     return redirect('login')
