I have 3 models, User, Company and Address.
Basically, a User belongs to a Company and an Address has one Company
(because it can be linked to other models).
In a form I want to display a User, its Company and its company Address,
The problem is when my User has a Company, that does not have an
the part containing the Address is not displayed.
I see 2 ways of instanciating my empty adress:
In the view:
f.fields_for :company, @user.company do |company_form|
and company_form.fields_for :address, (address = @user.company.address ?
address : Address.new)
In the controller
@user.company.address = Address.new unless @user.company.address
(a variant would be to write @user.company.build_address, which I prefer
Do you see other ways and what do you think is best?
