问题 I am having trouble with facebook API call. I am using Koala for server side api call but recently came into issue making api call. So I tried to bypass koala call and did raw api http call using call but to no avail. When I do curl from development machine it works fine. curl "https://graph.facebook.com/me?oauth_token=my_token It returns profile details, but the same thing done from production machine, it's throwing the exception {"error":{"message":"Cannot call API on behalf of this user",

问题 I'm trying to retrieve a user name to insert into a comment on a blog post using rails if I use <%= comment.user_id %>" it will give me an id but if I try and retrieve the user then call the name it return nil class <%= User.find_by_id(comment.user_id).name %>" why is this not working if I leave .name off it returns a space in memory. #<User:000x00000182fe48> 回答1: Most likely, the dynamic finder is getting confused by the id and is returning the (Ruby) object's id (i.e. object_id ) instead of

问题 I have an ActiveRecord, Annotation, with two columns: user_id and post_id, which can be null. An annotation with null user_id and post_id are "global" annotations that are applicable to all posts across all users. I would like to retrieve all annotations associated with a particular user's post AND all global annotations. In MySQL, the SQL command would be select * from annotations where (user_id = 123 and post_id = 456) or (user_id is null and post_id is null) In Rails 3, what is best way to
