Hey there Amador,
I must confess, I am not a rails guru here but, according to the
documentation I have, the part that reads
<%= f.select('entry', 'type_id', EntryType.all.collect {|t| [t.description,
t.id]}, {:include_blanks => 'None'}) %>
should end with a *{ :include_blanks => false } *not with a *'None'* string
value.
The other thing here is, if an annotation of your models look something like
this:
# Table name: entities
#
# id :integer not null, primary key
# type_id :integer
.
.
.
# created_at :datetime
# updated_at :datetime
# Table name: entity_types
#
# id :integer not null, primary key
# type :string(255)
.
.
.
# created_at :datetime
# updated_at :datetime
Then in my understanding rails make the relationship between the two models
if you have a field name containing the name of the table you want link to
followed by an underscore and the name of the primary key of the referred
table: *i.e. enty model needs an entity_type_id field not type_id. *
Well I guess that all I can see from what you have provided but like I said
I am not an expert and I stand to be corrected. Hope this helps

Tsega
