I have a controller which is passed params[:transfer] from a form. I
want to add some key vale pairs so the .create(params[:transfer] used
later has the other data base columns not populated in the form.
thanks

If I understand the question right, you want to add to the
params{:transfer] hash so you can use/modify it later, possibly during
a create.
One possibility is that if you are not using it right away is to just
store it in your session:
session[:transfer] = params[:transfer]
session[:transfer] [new_key]= new_val # then add vals to it as
required
then later on within the session…
SomeModel.create(session[:transfer])
hope this helps

Foo.create( {:foo => ‘bar’, :one => 2}.merge(params[:transfer]) )
This way you can set all the defaults and anything specified in
params[:transfer] will over write them…

Thanks, I’ll try it out and let you know.
Another option may be to set the other fields (which have fixed values)
through the view by using MagicFieldNames

Does that make sense ?

philip, sorry I don’t quite understand. Is Foo the hash? with two key
value pairs where
key is :foo and value is ‘bar’
key is :one and valie is ‘2’
and this is then merged with params[:transfer]
Don’t I need to declare Foo ?

Got it ! I used
foo = {:status => 'pending', :initiation_method => 'user'}
params[:transfer].update(foo)
...
...
.create(params[:transfer])
The table is now created with the other columns

I used Foo to represent whatever your model is.
