Question

Currently I have an each loop in the template for where the comments are display. Say a user has 50 comments to a micropost they have posted. A long list showing 50 comments will be displayed.

To save space on the page I’ve decided I’d like to limit comments shown to 2-3 per micropost. If a user wishes to view more they can click “view more” or “view all”. I’m wondering how a server would cope if there were like 10,000 comments and a user clicked “view all” which is why I may choose to implement “view more” then have like 50 more comments shown”

Anyway I’d like to know a good way to limit the amount of comments shown to a user until they choose to view all?

If I go the jquery/js route and make it so only the 2-3 most recent messages are shown the others would have still been loaded back end wouldn’t they so wouldn’t a better option be to control this in ruby on rails some how?

I’d really like some nice solutions/info on the best way to do this.

Any further info you need I’d be happy to provide.

Thanks
Kind regards

You can do like Facebook:

• Show only 2/3 comments. Load only 2/3 comments from the backend.
• When the users clicks “Show more”, it shows 50 more. It loads them through AJAX. So on the backend you only get a request like “GET 50 comments EXCEPT the three firsts”.
• Another “Show more” link is shown. It will load 50 other comments except the 53 firsts.

On Facebook, you can’t load more than 50 comments at once. I think you should do the same.
