I am trying to create a listing of objects in a table with a drop down box to edit one particular aspect of each thing in the list , but I can not even get the form to render without getting a NoMethodError. Currently I have something like this:

\<% for thing in @things %\> &nbsp;&nbsp;//...table stuff here... &nbsp;&nbsp;&nbsp;&nbsp;\<td\>\<%=h thing.element1 %\>\</td\> &nbsp;&nbsp;&nbsp;&nbsp;\<td\>\<%=h thing.element2 %\>\</td\> &nbsp;&nbsp;&nbsp;&nbsp;\<td\>\<%=h thing.element3 %\>\</td\> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;//...etc, etc, and then I have the following which give me a NoMethodError... &nbsp;&nbsp;&nbsp;&nbsp;\<td\>\<%= select('thing', 'elementx', ['choice1', choice2'], :selected =\> thing.elementx ) %\>

\<% end %\> \</table\>

Of course, once I fix this get the form to actually render, I still haven't quite figured out how I would then update all instances of this object with their (possibly new) values. I assume that I would just have to iterate through @things and call update\_attributes on each element, but I'm not quite sure how to do that

Sorry if this is a bit of a stupid question, I'm a still learning.

Thanks, Paul
