Custom css with kaminari with bootstrap

Question

I try to use paginate with kaminari. My project used bootsrap css, and the result is so ugly:)

The html is generated by nokogiri

<nav class="pagination">
    <span class="first">
  <a href="/admin/book_borrow/borrow?locale=en">« First</a>
</span>

    <span class="prev">
  <a rel="prev" href="/admin/book_borrow/borrow?locale=en">‹ Prev</a>
</span>

        <span class="page">
  <a rel="prev" href="/admin/book_borrow/borrow?locale=en">1</a>
</span>

        <span class="page current">
  2
</span>

        <span class="page">
  <a rel="next" href="/admin/book_borrow/borrow?locale=en&amp;page=3">3</a>
</span>

        <span class="page">
  <a href="/admin/book_borrow/borrow?locale=en&amp;page=4">4</a>
</span>

    <span class="next">
  <a rel="next" href="/admin/book_borrow/borrow?locale=en&amp;page=3">Next ›</a>
</span>

    <span class="last">
  <a href="/admin/book_borrow/borrow?locale=en&amp;page=4">Last »</a>
</span>

  </nav>

I want something like pagination in bootstrap page, how I can do? Please help!

Answer 1

After I posted this question I found the solution: kaminari: A Scope & Engine based, clean, powerful, customizable and sophisticated paginator for Rails 3.

Just go to the console and type:

rails generate kaminari:views bootstrap4

It will download some Haml files to your application, and the views are changed. It also supports bootstrap 2 and 3 e.g

rails generate kaminari:views bootstrap3

Here are some themes for Kaminari views: https://github.com/amatsuda/kaminari_themes

simply add following css to your application.css

.pagination a, .pagination span.current, .pagination span.gap {
    float: left;
    padding: 0 14px;
    line-height: 38px;
    text-decoration: none;
    background-color: white;
    border: 1px solid #DDD;
    border-left-width: 0;
}

.pagination {
    border-left: 1px solid #ddd;
    .first{
        padding : 0;
        float: none;
        border: none;
    }
    .prev {
        padding : 0;
        float: none;
        border: none;
    }
    .page{
        padding : 0;
        float: none;
        border: none;
    }
    .next{
        padding : 0;
        float: none;
        border: none;
    }
    .last{
        padding : 0;
        float: none;
        border: none;
    }
}

This is excellent advice. I also added one more line of css: a:hover { background-color: lightgreen; } That adds a hover action on the pagination links. This was tested on Rails 5.1 and bootstrap 3. – Copaiba

Nearly gave up until I found "Pagination with Kaminari".

In short, after rails g kaminari:default go into the views that are created under app/views/kaminari and change the tags to suit your styling.

I went into _paginator.html.erb and changed the <nav> to a <div> and replaced all the <span> tags with <li>.

To get the bootstrap styling that fits my app, I changed the <div> tag in _paginator.html.erb to <div class="pagination pull-right"> and the <span class="page"> tags to simple <li>.

There's are a couple of gotcha's that perhaps someone else can help with:

1. There's erb in _page.html.erb that changes the class for the current page when active. It messes up the alignment so to get around that, change the <%= link_to_unless page.current? ... %> to <%= link_to page ... %>.

2. The _gap.html.erb view which inserts the "..." block also gets messed up. Replace it with <li><%= link_to '...' %></li> to get it to sit nicely inline.

I just started coding 8 weeks ago so for sure there are better ways to approach this and ways to clean up 1 and 2, but if you just want things to look right and function as intended, give that a shot and fine tune later.

hi, nice try! But there is an easier way. you can use bootstrap theme for kaminari, it's automatic – Humes

Hi Duykhoa - Thanks for the comment. Hopefully the response is still helpful for those who wish to customize the theme. – Unscrew
