如何不在django社交中设置用户的电子邮件地址

我有django social-auth（来自omab）安装，用户在数据库中有一个电子邮件地址，我想保留这个地址，但是当用户使用social-auth从facebook登录时，他们的电子邮件被他们的电子邮件替换在他们的Facebook帐户。 我不确定这些设置是否为默认设置，也无法找到如何阻止此行为。

您是否尝试过SOCIAL_AUTH_PROTECTED_USER_FIELDS ？ :)

从手册：

update_user_details管道处理器将在用户对象（如电子邮件）上设置某些字段。 将其设置为您只想为新创建的用户设置的字段列表：

SOCIAL_AUTH_PROTECTED_USER_FIELDS = ['email'，]

如果定义，还会存储更多的额外值。 有关此设置的详细信息在下面的OpenId和OAuth部分中列出。

我发现它，正在筹备中

social_auth.backends.pipeline.user.update_user_details

我只是从管道中删除它，现在像电子邮件地址和名称的详细信息留给用户填写。

我发布我的解决方案（更新用户详细信息，而不是覆盖它们），以便它可以帮助某人。 根据pipeline.user.update_user_details我编码如下：

def fill_user_details(backend, details, response, user, is_new=False, *args,
                        **kwargs):
    """Fills user details using data from provider, without overwriting
    existing values.

    backend: Current social authentication backend
    details: User details given by authentication provider
    response: ?
    user: User ID given by authentication provider
    is_new: flag

    source: social_auth.backends.pipeline.user.update_user_details
    """
    # Each pipeline entry must return a dict or None, any value in the dict
    # will be used in the kwargs argument for the next pipeline entry.
    #
    # If any function returns something else beside a dict or None, the
    # workflow will be cut and the value returned immediately, this is useful
    # to return HttpReponse instances like HttpResponseRedirect.

    changed = False  # flag to track changes

    for name, value in details.iteritems():
        # do not update username, it was already generated
        if name in (USERNAME, 'id', 'pk'):
            continue

        # set it only if the existing value is not set or is an empty string
        existing_value = getattr(user, name, None)
        if value is not None and (existing_value is None or
                                  not is_valid_string(existing_value)):
            setattr(user, name, value)
            changed = True

    # Fire a pre-update signal sending current backend instance,
    # user instance (created or retrieved from database), service
    # response and processed details.
    #
    # Also fire socialauth_registered signal for newly registered
    # users.
    #
    # Signal handlers must return True or False to signal instance
    # changes. Send method returns a list of tuples with receiver
    # and it's response.
    signal_response = lambda (receiver, response): response
    signal_kwargs = {'sender': backend.__class__, 'user': user,
                     'response': response, 'details': details}

    changed |= any(filter(signal_response, pre_update.send(**signal_kwargs)))

    # Fire socialauth_registered signal on new user registration
    if is_new:
        changed |= any(filter(signal_response,
            socialauth_registered.send(**signal_kwargs)))

    if changed:
        user.save()
