Limiting Number of Posts Per Page - Ruby on Rails Blog

Question

I am currently developing a Ruby on Rails blog. I have my blog posts show up on the main page, however, I would like to list the posts 5 at a time, so that my frontpage doesn't go on forever and my blog will look much cleaner.

Let me know if you can help. Much appreciated.

Answer 1

Looks like you need a pagination solution - consider using kaminari or will_paginate ( https://github.com/amatsuda/kaminari , https://github.com/mislav/will_paginate/wiki )

And if you need an endless page, there is a nice screencast about that: http://railscasts.com/episodes/114-endless-page

Answer 2

For example, if using will_paginate for pagination, you just call paginate method at end of line your query inside controller, for example inside your controller

def index
  @blogs = Blog.all.paginate(:page => params[:page], :per_page => 5)
end

from your view, just simply put:

will_paginate @blogs

at specify location, to show pagination.

Answer 3

If I understand right, you want to limit the number of post on the home page . Then you should do like

Model.find(:all, :limit => 5, :order=> 'created_at desc')

you can remove the order if you don't need it. If you need to make pagination take a look at will_paginate
