Rails getting undefined method for existing field in database

问题

So I have a field in the question table, called is_public..I migrated my database, restarted it and now when I get this error everytime I call is_public for a record in the question records.

undefined method `is_public' for #<Question:0x7e9aa780>

Any ideas to why this is happening ?

回答1:

Are you using attr_accessible? If so, add :is_public to the list.
