Ruby Advanced Social Features in Ruby on Rails Create an Image Gallery Creating Albums and Pictures

I've added all the code up until the very last step in the video, whereupon i get error : undefined method "pictures"

How do i fix this?

Can you add your code so that it can be viewed by others. That will allow others to better assist you with the problem.

From what you've explained, I would make sure that you have actually defined the method "pictures" properly in your code. Make sure it's not a typo. If all is well then make sure what you're passing to it is properly done. Also, when you read the error message, it should tell you where the problem is (what line it's on) in your code and will help narrow it down for you. Sorry if this doesn't help, but without seeing your code it could be a number of things and I won't be able to pin point it for you.

Sounds like to me there is a missing

has_many :pictures

in the album model.

Also to note that this course is NOT rails 4 compatible and you will run into some errors because things change more quickly than videos can be made. The ideas behind these features can easily be integrated into any rails app though.
