Question

<% @labels.each do |label| %>
    <input type="text" name="<%=label.name%>" value="<%=@car.(label.related_to) %>" class="big-font" style="width: <%=label.width%>px; top: <%=label.y_coor%>px; left: <%=label.x_coor%>px;" /> 
<% end %>

Hello guys, I’m new to rails so this should be a fairly easy question to answer.

The issue is here: <%=@car.(label.related_to) %>.

label.related_to holds the string “make”. I’m trying to get it to do this pretty much: @car.make

Any idea guys?

Thanks,
Alain

Answer 1

Use send to send a message to an object:

@car.send(label.related_to)

If there is any chance of label.related_to not being a valid method for the object, you’ll probably want to be prepared to catch the NoMethodError
