在“显示操作”中显示当前帖子以外的其他帖子

Question

This is probably an easy question, but can't find it for the life of me..

On a post's show action, I'm trying to show in a small sidebar all of the other posts of that user besides the current post. Im using a loop with

@post.user.posts.limit(6).shuffle.each do 

i would think you could do

.except(@post)

or something similar to exclude the current post but that didn't do the trick. Does anyone know how to do this??

Answer 1

You can easily do it via SQL:

@post.user.posts.where("posts.id <> ?", @post.id).limit(6).shuffle.each do
# same thing but wrote differently:
@post.user.posts.where("posts.id NOT IN (?)", @post.id).limit(6).shuffle.each do
