Rails 2.0.2 and Can't mass-assign these protected attributes

Rails
1

Hi there:

I’m playing around with a form that saves name, type and date for a
kind of travels. At the controller I have this:
@promotion = Promotion.new(params[:promotion])
@promotion.save
redirect_to promotions_path
So yes, I mass-assign all the form data, but my model definition is
empty actually (no “attr_protected”, no “attr_accessible” anywhere),
but the message “WARNING: Can’t mass-assign these protected
attributes: type” shows up every time and the value for “type” gets
saved as empty (NULL) on development environment.

I’ve found this thread at the group but it doesn’t solve my problem:
http://groups.google.com/group/rubyonrails-talk/browse_thread/thread/fe5263558f73a514/ecee69cdf4676123?lnk=gst&q=Can’t+mass-assign+these+protected+attributes#ecee69cdf4676123

Any ideas about what is protecting this attribute from myself?.

Cheers, Ibon.

type is a magic column name (used for STI). You can change the magic
STI column to something else with inheritance_column

Hi Fred:

Appreciate the clarifying comment. I think that I have prefer to
change my column name rather than the magic one. By the way, what does
STI means?.

Cheers, Ibon.

Depending on the context, Single Table Inheritance or Sexually
Transmitted Infection.
