我想创建一个允许user（UserProfile扩展的OneToOne）成为translator的表单。这意味着如果User已登录，他/她可以点击Become a Translator按钮，将其重定向到预先填写的表单。如果UserProfile中没有此类属性，则应预先填写此表单。
因此，如果有人已经填写了他的姓氏，那么姓氏应该以这种形式预先填写，否则，他必须填写它，因为对于译者来说，这是必需的。
所以我试图将user.userprofile参数作为表单类的属性，但它引发了：
'UserProfile' object has no attribute 'get'
你能给我一些提示吗？

答案 0 :(得分：2)
您将request.user.userprofile作为TranslatorRegistrationForm的位置参数传递到此行：
register_as_translator_form = TranslatorRegistrationForm(request.user.userprofile)
你应该把它作为关键字参数传递，因为Django表格期望data（POST / GET）作为第一个位置参数。
如果您的表单在__init__方法中接受userprofile关键字参数，则应将其作为关键字参数传递。像这样：
register_as_translator_form = TranslatorRegistrationForm(user=request.user.userprofile)
如果要将初始数据传递给表单，可以使用initial关键字参数传递它。
initial_data = {'name': 'John'}
register_as_translator_form = TranslatorRegistrationForm(initial=initial_data)
注意：初始数据密钥必须与您的表单字段匹配。
