Rails - May 2006 - trouble creating new records

Is it possible to create / save a new record from a controller other than the
one I specified when I created the scaffolding?

My situation is that I have two tables.  Emrecs is the parent.  Actors is the
child and has a foreign key named emrec_id that references emrec.id.  I
scaffolded both, creating controllers and views for each.  My app collects info
from the user to fill in the two tables, then writes the info collected out in
an XML file.

Now I need to read in the XML file and put the data back into the tables.

Any suggestions?  Right now it looks like I''m going to have to open a
new REXML doc in each controller.  Is that right?

Thanks in advance!

Bill

Absolutely, from any controller anywhere in your app you can simply do

emrec = Emrec.new(:some_param => ''foo'')
emrec.actors << Actor.new(:another_attribute =>
''bar'')
emrec.save

You can abstract any common code to a private method in 
app/controllers/application.rb.  All controllers inherit from 
ApplicationController so any methods you want shared between multiple 
controllers should go here.

Hi Alex,

Thanks for your reply.  It confirms what I thought was the case.  It turns 
out I''d made a couple of (compounding) stupid-newbie mistakes.  1)  I
wasn''t
populating a field I was validating (so of course the save didn''t
happen
;-p ) and 2) I was using a created (as opposed to scaffolded) view and 
hadn''t put <%= error_messages_for ''table_name''
%> in it so I wasn''t seeing
the error messages that would have steered me to a solution without wasting 
bandwidth on the list.  Sorry for the noise.  But thanks again for your 
reply.

Best regards,
Bill
