attr_accessor

Folks, newbie here and I have a quick question about attr_accessor.

I'm developing a very basic CMS and I set up a simple class for a user. In that class I use attr_accessor to set up the read, write, etc methods.

Then in a very basic a controller I create an instance variable @post = post(:all) and I then render the title of the post along with the user name in the view. Strangely, the title appears, but the user name doesn't. BUT, if I remove the attr_accessor in the model the user name appears just fine. I thought that attr_accessor didn't do that and that methods like attr_accessible or attr_protected should be used instead to restrict access to the method.

What's happening here? Do miss understand how attr_accessor works?

TIA!

I suspect the attr_accessor is overwriting the accessor methods that rails creates for your database attributes. attr_protected etc... are only for dealing with mass assignment (ie Post.new(params[:post])))

attr_accessor is a Ruby (not Rails) thing that sets up "getter/setter" methods for an instance variable. You shouldn't use attr_accessor for the columns in an AR model; AR creates getter/setter methods for you.

What are you trying to accomplish with attr_accessor here?
