Question

This is my code and it is loaded in a helper-class

output += '<button class="del_account" param-del="{account.id}">delete</button>'

When I render this to html, account.id is just converted to a string. And not the ‘id’ that I need. How can I solve this? Because this isn’t working either.

output += '<button class="del_account" param-del="#{account.id}">delete</button>'

or this

output += '<button class="del_account" param-del="' +account.id +'">delete</button>'

thanks for your help.

You could use the Rails helper method content_tag (documentation) which makes things a bit cleaner and more readable.

output += content_tag(:button, "delete", :class => "del_account", :'param-del' => account.id)

Also, technically ‘param-del’ makes your HTML invalid – your custom attributes should begin with ‘data-‘, so updating above would become:

output += content_tag(:button, "delete", :class => "del_account", :'data-account-id' => account.id)
