Ryan,
For Glenn's issue we're assuming that params[:blah] is a hash upon
which you call Hash#delete_if. As for yours, params[:post] is a hash
and params[:post][:blah] returns the hash value with key :blah.

Sometimes I find I have to do a params[:post][:blah]. Haven't
figured out exactly why yet..

Glenn,
This is a simple one liner:
params[:blah].delete_if {|k,v| v.blank?}
Cheers.

We've got a situation where we're setting up params[:blah]
in a form. When the form is submitted, we do a
Model.find(:first, :conditions => params[:blah])
This generates a SELECT with all the params, but the
problem is that if the user left some fields blank,
the WHERE conditions end up looking like
WHERE some_field = ''
which is accepted by mysql, but fails on certain field
types ( e.g. Integer) in postgres. What we really want
in most cases would be no specified condition at all
corresponding to blank fields, or perhaps flag an error.
Is there anything already in rails that I might be missing
that exists to deal with this situation?
Thanks...
