Parse.com在Android中将对象添加为关系

Question

I am having trouble adding my message as a relation in parse. I am not getting any error and nothing is submitting inside of Parse.

Group has relationship Messages Group has already been set at the top of the page.

ParseObject messageToSend = new ParseObject("Message");
messageToSend.put("FromUser", ParseUser.getCurrentUser());
messageToSend.put("Content", uiMessageToSend.getText().toString());

ParseRelation<ParseObject> relation = Group.getRelation("Messages");
relation.add(messageToSend);

Group.saveInBackground();

Answer 1

ParseObject messageToSend = new ParseObject("Message");

        messageToSend.put("FromUser", ParseUser.getCurrentUser());
        messageToSend.put("Content", uiMessageToSend.getText().toString());

        ParseRelation<ParseObject> relation = Group.getRelation("Messages");
        messageToSend.put("YOUR_RELATION", relation);

        messageToSend.saveInBackground();
