will_paginate

will_paginate is a pagination library that integrates with Ruby on Rails, Sinatra, Hanami::View, and Sequel.

gem'will_paginate','~> 4.0'

Seeinstallation instructions on the wiki for more info.

ℹ️ will_paginate is now inmaintenance mode and it will not be receiving new features.See alternatives

Basic will_paginate use

## perform a paginated query:@posts=Post.paginate(page:params[:page])# or, use an explicit "per page" limit:Post.paginate(page:params[:page],per_page:30)## render page links in the view:<%=will_paginate@posts %>

And that's it! You're done. You just need to add some CSS styles tomake those pagination links prettier.

You can customize the default "per_page" value:

# for the Post modelclassPostself.per_page=10end# set per_page globallyWillPaginate.per_page=10

New in Active Record 3:

# paginate in Active Record now returns a RelationPost.where(published:true).paginate(page:params[:page]).order(id::desc)# the new, shorter page() methodPost.page(params[:page]).order(created_at::desc)
