如何在python-social-auth django中設置額外的數據？

Question

我有一個問題，當嘗試使用管道保存額外的數據但沒有保存時​​。 這里是一個代碼：

def save_picture(strategy, user, response, details,social_user,
            is_new=False, *args, **kwargs):

if is_new and strategy.backend.name == 'facebook':
    url = 'http://graph.facebook.com/{0}/picture'.format(response['id'])
social_user.set_extra_data('url':url)

也許我必須使用其他方法？

我找到了django-social-auth的解決方案，但是它們不適用於python-social-auth：

social_user.extra_data['your_field']

但是它們不起作用，我嘗試使用

social_user.set_extra_data({'url': url})

但這引發了例外：

我解決了，下面的代碼可以解決問題。

def get_user_avatar(strategy, details, response, uid, user, *args, **kwargs):
    social = kwargs.get('social') or strategy.storage.user.get_social_auth(
        strategy.backend.name,
        uid
    )
    url = None
    if strategy.backend.name == 'facebook':
        url = "http://graph.facebook.com/%s/picture?type=large" % response['id']

    if url:
        social.set_extra_data({'photo': url})
