Rails gemのkaminariとBootstrapを共存させる方法 #Ruby

kaminariのインストール

Gemfileに以下を記述

gem 'kaminari'

gemのインストール

$ bundle install --path vendor/bundle

Bootstrapに対応させるためのfileをインストール

$ rails g kaminari:views bootstrap
downloading app/views/kaminari/_first_page.html.erb from kaminari_themes...
create app/views/kaminari/_first_page.html.erb

create app/views/kaminari/_gap.html.erb

downloading app/views/kaminari/_paginator.html.erb from kaminari_themes...
create app/views/kaminari/_paginator.html.erb
downloading app/views/kaminari/_prev_page.html.erb from kaminari_themes...
create app/views/kaminari/_prev_page.html.erb

たくさんファイルが出来ました。
後は、同じようにcontrollerとviewを弄るだけです。

model

article_controller.rb

def index
#1ページ毎に5件ずつ表示
  @articles = Article.page(params[:page]).per(5)
end

view

index_html.erb

<html>
...
<% @articles.each do |article| %>
    <%= article.title %>    
<% end %>
<%= paginate @articles %>
...
</html>

というような感じでページングが出来ますので後はご自由に調整してください。
