Question

我是Django的新手。我已经阅读了文档，并且在这里查找了所有内容，但是数量不多。我基本上是想让个人资料显示在我已经创建的页面上。我正在使用自定义用户模型。

问题是，建议我只在“ user = request.user”中取出“ user”，但是问题是如果这样做，我将无法获得“ Profile”。

第description = Profile.objects.get(user=request.user).description行出现错误：

FieldError at /mingle/
Cannot resolve keyword 'user' into field. Choices are: date_joined, description, email, given_vote, id, is_active, is_admin, is_staff, is_superuser, last_login, logentry, matches, password, photo, username, uservote

Answer 1

您是否在settings.py中设置了AUTH_USER_MODEL来指向您的自定义Profile模型？如果是这样，request.user将已经是您要过滤的用户。

您可以更改：

description = Profile.objects.get(user=request.user).description

收件人：

description = request.user.description

无法将关键字“用户”解析为Django字段
