I have:
class Company < ActiveRecord::Base
has_many :categorizations
has_many :categories, :through => :categorizations
has_many :managements
has_many :managers, :through => :managements
has_many :tenders
has_many :documents, :dependent => :destroy
accepts_nested_attributes_for :managers
accepts_nested_attributes_for :documents
accepts_nested_attributes_for :categorizations
then the form is:
= semantic_form_for @company do |f|
= f.input :name
= f.semantic_fields_for :manager do |manager|
= manager.inputs :name, :fiscal_code, :city, :zip_code, :address,
:street_number, :tel, :email
when I submit the form raise the error:
unknown attribute: manager
{"utf8"=>"✓",
"authenticity_token"=>"V5GsRKLK8cRrGuUh2Jv4DB9wSYWG8ASCxHkd0Ur3o8s=",
"company"=>{"manager"=>{"name"=>"",
"fiscal_code"=>"",
"city"=>"",
"zip_code"=>"",
"address"=>"",
"street_number"=>"",
"tel"=>"",
"email"=>""}},
"commit"=>"Create Company"}
I think there is nothing wrong but perhaps I miss something.

To validate this hypothesis, try something like, e.g. in rails console> Company.new.methods.grep(/manager/)and check which exact methods are available for ''manager*'' on the Company class. I would expect you see there: [... :managers_attributes=, ...] I think (not sure) a second problem is that the has_many requires an array there ... So, you should change your form to create parameters like this: "company"=>{"managers_attributes"=>[ # key changed; changed into array {"name"=>"P", "fiscal_code"=>"1", "city"=>"2560", ...}, {"name"=>"S", "fiscal_code"=>"2", "city"=>"2500", ...}]}, ... Also see: http://api.rubyonrails.org/classes/ActiveRecord/NestedAttributes/ClassMethods.html Which shows as example: class Member < ActiveRecord::Base has_many :posts accepts_nested_attributes_for :postsend You can now set or update attributes on an associated post model through the attribute hash. For each hash that does *not* have an id key a new record will be instantiated, unless the hash also contains a _destroy key that evaluates to true. params = { :member => { :name => ''joe'', :posts_attributes => [ { :title => ''Kari, the awesome Ruby documentation browser!'' }, { :title => ''The egalitarian assumption of the modern citizen'' }, { :title => '''', :_destroy => ''1'' } # this will be ignored ] }} Not entirely sure, but I think this is your problem.

But now I have a question: if I do semantic_fields:_for :manager without doing @company.managers.build I see the manager form. Why I see the manager form? Do fields_for :manager call the manager controller? -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
