Rails helper working with template

ruby-talk
1

Hi,

I'm trying to develop a Rails component to display a Ruby array as a html table (which could evolve in something equivalent to CKHTMLTable for cgikit).

I use a helper:

#Helper method that can be used in the main template:
   def html_table(ar)
     @working_array = ar
     render("htmltable")
   end

and here's the template rendered by the helper method:

#template used by the helper (htmltable):
<table>
<%for a in @working_array %>
     <tr>
     <%for element in a%>
     <td><%=element%></td>
     <%end%>
     </tr>
<%end%>
</table>

That enables me to do this
<%=html_table(@list)%>

in my application template, and will display the array @list as html table.

The problem is that the working_array variable has to be used as instance variable, possibly introducing naming collisions....

Is there a nice solution to this?
Or could a new render_* method be helpful, using all variables available where it is called (even non instance variables)?

Thanks.

PS: not that I want to reopen the debate there was when comparing cgikit and rails, but isn't the binding file preventing such naming collisions?
