1,860 PointsAdding attr_accessible causes crash
Hey guys. When I add attr_accessible to status.rb, my application crashes and gives this error:
undefined method `attr_accessible' for #<Class:0x00000102fd7368>
...with line 2 of status.rb highlighted. I'm not really sure how to troubleshoot this - RoR is still pretty unknown to me.
As an aside, I'm finding this track is going past pretty quickly, it's been tough to follow in parts.
If anyone has an idea about what I might be missing, that would be very helpful!
Cheers Hugo

There have been a lot of threads on this topic. Here is one of the ones that explains your issue a bit: Attr_accessible Issue
Just to let you know that since Rails 4.0, attr_accessible is no longer supported directly with rails, but as mentioned in that linked topic, you can get a gem to support it if you wish.
I recommend following the Creating a Todo List Application courses from Treehouse as they were made specifically for Rails 4.
If you want to continue to follow the course you are on to make the Social Network, you could install that gem, or even better, revert to the same version of Rails used in that course (Rails 3.2.13)
Hope this helps

My problem was that the form was not permitting me to save :user_id and therefore there was no way to match the the users table. I hope this helps.
def status_params params.require(:status).permit(:name, :content, :user_id) end

1,860 PointsThanks John! I'll remember to do a more comprehensive search in future - perhaps including that in the 'ask a question' UI in addition to the 'questions like this' suggestions would have headed this question off at the pass!
