在Rails的link_to内设置文本的ID

Question

I have a dropdown list having links to specific categories, in each line of category I want it to include name of category and number of books of that category. Anyway, I want the number part having a different style in comparison with name part.

Here is the code for each one:

%li= link_to "#{category.name} (#{category.books.count})" , root_path(category_id: category.id)      

I want to set id for #{category.name} and (#{category.books.count}) , what should I do?

Answer 1

You should define the attribute id . In your code, you should do it like:

%li= link_to "#{category.name} (#{category.books.count})" , root_path(category_id: category.id), id: "#{category.name} (#{category.books.count})"

Answer 2

I found the answer, we should use link_to do like this:

 = link_to root_path(category_id: category.id, per_page: params[:per_page]) do
          .row.cate-display
            #cate-name= category.name
            #cate-count= "(#{category.books.count})"
