Lets say I wanted to make a function to return someone's age from a rails database.
function getName(name_input) {
return <%= Names.find_by(name: name_input).age %>
}
When I've tried similary functions is seems that rails doesn't have access to local variables. Is there a workaround?
getName is a Javascript function that gets called on the client side. Code in <%=%> is executed at the server before sending the HTML view to the client; at that moment, Rails has no idea what name_input is.
Please try using <%= Names.find_by_name(name_input).age %>
<% %> are erb tags which embed Ruby inside HTML that your rails server will render and send to the client as pure HTML.
You cannot mix server-side ruby with client-side javascript.
