I wanted to add an image with text inside my link_to so I wrote this piece of code that is working fine :
<%=link_to image_tag('fleche_droite.svg') + "Ajouter un joueur à la liste", invite_player_path(@tournament), class: "btn btn-success", id: "convocation-submit" %>
the problem is that I need to add a specific class to my image to give it the right size. How can I do that within the rails helper ?
