update_attributes not saving data

Carl Brown

3/26/2006 7:24:00 PM

The run logs all look good and the data seems to be pre-set but the SQL
generated has none of the changed data...

This 'doesn't work:
id = session[:customer_id]
@customer = Customer.find( id )
@customer.updates_attributes(params[:customer])


And, this 'does' work:
id = session[:customer_id]
@customer = Customer.find( id )
p = params[:customer]
@customer.first_name = p[:first_name]
@customer.last_name = p[:last_name]
@customer.save


Any ideas? (And, yes, there is an IF around the update_attributes that
indicates all-is-well...)

Thanks!!

Do you have :customer set in the Customer model as attr_accessor? I
recall having a similar problem where specifying attr_accessor for my
attribute resulted in the attribute being updated as NULL - not with the
value I expected.

Ask on the Rails mailing list.

Oh... Wow -- thanks! That would probably work, too....

I removed the attr_accessor entirely and that resolved the issue. I
apparently have no clue how these models work yet...

Thanks for the tip!
