I’m building a calendar/scheduling application that has a bunch of  
little pulldowns to let doctors note appointment status for a given  
timeslot. I got the ajax call working with a submitbutton - but I  
really want it to update the database as soon as a doctor selects a  
new value for the appointment status.

\<% remote\_form\_for(slot.get\_todays\_appointment do |f| %\>  
\<%=h slot.get\_todays\_appointment.patient.first\_last\_name %\>  
\<%= f.select :status, Appointment::STATUS\_TYPES, :prompt =\> false %\>  
\<%= submit\_tag “Update” %\>  
\<% end %\>

I’ve tried to use an observer tied to the drop-down but that keeps  
returning ‘null value’ and I’ve tried to use everything I can think  
of for the identifier ‘appointment\_status’ and ‘appointment[status]’.  
Here’s the HTML that the above ruby code generates:

David Atkinson --- 211 213 214 215 PaceMkr Hospital No Show Complic Schdl Abs

So what am I doing wrong? I just want to be able to have the form  
submit onChange rather than having someone have to click a button.

So they key bit here is the observer, but that’s the bit you haven’t  
shown :-). Alternatively stick an onChange on your select

I figured it out – you simply attach the observer … I was making it  
more complicated than it was. Makes me love Rails all the more – so  
simple!
