Hi,

I know about pagination but dont want to use that option if it all  
possible.

How in a collection of posts can i check if the there is a next item in  
the collection and then add that an object.

For instance:  
//Returns all the posts into a collection called posts  
@posts = Post.find(:all)

//Returns a specific post based on an id  
@post = Post.find(params[:id])

//How can i return the next post something similar to below. Do i need  
to write a custom Post.find\_next\_item(params:id) in the post model?  
@nextpost = Post.find(params[:id]).Next

Can anyone point me in the right direction?

Ive figured out how to do this.

All i need to know is how return the contents of 1 field from an sql  
statement on the posts table.

//This is a variable that i want the id of the next post to put into  
nextid = Post.find(:select =\> “id”,  
:conditions =\> “id \< 19”,  
:order =\> ‘id ASC LIMIT 1’)

This si the next post i want to find passing in the id from above.  
@nextpost = Post.find(params[nextid])

Any Examples, i cant find anything on the net?
