datatables-rails-bs3's Issues

Sortable Arrow Images Not Showing

Currently the sortable arrow images are not showing. This could be a relative path issue because of the asset pipeline or some type of styling problem.

Sortable Arrow Images Not Showing

I use datatables-rails-bs3 with my Rails 4 project, and I got an exception in production mode.

GET http://www.pandacourse.com/assets/datatables/sort_asc.png 404 (Not Found) admin-e14a70de3039aadeed15c39473a436ad.js:2
GET http://www.pandacourse.com/assets/datatables/sort_both.png 404 (Not Found) admin-e14a70de3039aadeed15c39473a436ad.js:2

In admin.js there are just 2 lines.

//= require dataTables/jquery.dataTables
//= require dataTables/jquery.dataTables.bootstrap

And I have added admin.js to Rails.application.config.assets.precompile

Rails.application.config.assets.precompile += %w( html5shiv.min.js respond.min.js admin.js )

Now, to fix this, I have to add following lines to my css file:

table.table thead .sorting { background: image-url('datatables/sort_both.png') no-repeat center right; }
table.table thead .sorting_asc { background: image-url('datatables/sort_asc.png') no-repeat center right; }
table.table thead .sorting_desc { background: image-url('datatables/sort_desc.png') no-repeat center right; }

table.table thead .sorting_asc_disabled { background: image-url('datatables/sort_asc_disabled.png') no-repeat center right; }
table.table thead .sorting_desc_disabled { background: image-url('datatables/sort_desc_disabled.png') no-repeat center right; }

Use image-url instead of url, and add all image filenames to precompile

Rails.application.config.assets.precompile += %w( html5shiv.min.js respond.min.js admin.js 
  datatables/sort_both.png datatables/sort_asc.png datatables/sort_desc.png 
  datatables/sort_asc_disabled.png datatables/sort_desc_disabled.png )

It works.

But I think it's better to be done in your engine file.
