Newbie: I just want to exclude two attributes when I call update_attributes

Rails
1

I have two virtual attributes in my model. Let’s call them
“hours_worked”
and “minutes_worked”.

I use them to calculate “work_time”, which is an integer I store – it’s
the total minutes worked (e.g. 3.5 hours is 210).

I want :hours_worked and :minutes_worked to NEVER appear in the
database.

But when @foo.update_attributes(params[:foo]) is called, it bombs.

Any help would be appreciated. Thirty years software development
experience
and I just can’t seem to pick up Rails. ARGH!!!

What do you mean it bombs? Show us what is in params[:foo] and the
error you get.

Colin –

I ended up using

.slice(:field1, :field2, :field4)

in my update. Works fine.

You still haven’t shown us what’s in params[:foo] and the exact error
you get.

And in the Create method as well.

This FEELS wrong, but it works.
