解决方案

如果您对parse.com User类检查ACL栏，你会看到它有公共读取，但它并没有为公共写因此，如果您还没有登录以该用户无法更新行的信息。我相信你将不得不公开写入添加到用户的访问控制列表，如果你希望能够更新，而没有登录ID，虽然我不会推荐它。另一种解决方案是创建一个的parseObject存储非登录信息，这样你就可以在任何地方，因为ACL将被设置为默认的公共写更新。

I'm trying to grab a ParseRelation of user's who have joined a group. I had no problem until I added login with Facebook. Now, I get the error of "Cannot save a ParseUser that is not authenticated" when trying to add a user to the relation and then saving the ParseObject. I can join groups created by people who did not log in with Facebook and I can join groups that I created (I'm logged in with FB), but get the error with group's created by another user who logged in with Facebook.

mJoinButton.setOnClickListener(new View.OnClickListener() {@
  Override
  public void onClick(View v) {
    ParseObject group = mGroups.get(getAdapterPosition());
    mJoinedRelation = group.getRelation(ParseConstants.KEY_JOINED_RELATION);
    mJoinedRelation.add(mCurrentUser);
    group.saveInBackground(new SaveCallback() {

      @
      Override
      public void done(ParseException e) {
        if (e == null) {
          Toast.makeText(mContext, "You have joined the group!", Toast.LENGTH_LONG).show();

        } else {
          AlertDialog.Builder builder = new AlertDialog.Builder(mContext)
            .setMessage(e.getMessage())
            .setTitle(R.string.login_error_title)
            .setPositiveButton(android.R.string.ok, null);
          AlertDialog dialog = builder.create();
          dialog.show();
        }
      }
    });
  }
});

解决方案

If you check the ACL column on your User class on parse.com, you will see that it has Public Read but what it doesn't have is Public Write so you cannot update row information if you are not logged in as that user. I believe you will have to add Public Write to the ACL of that user if you want to be able to update while not logged id, although I wouldn't recommend it. Another solution is to create a ParseObject to store non-login information, that way you will be able to update it from anywhere since the ACL will be set up to Public Write by default.
