I would create a new company, assign a category and assign a
classification to the company.category all with one form.
Is it possible?
I think the only way is to create a new company and assign a category
with one form, then in the company controller or company model assign
a classification at company.category, the classification.id may be
passed as a parameter with the form.
What do you think about?
The models are:
has_many :categorizations
with one form, then in the company controller or company model assign
a classification at company.category, the classification.id may be
passed as a parameter with the form.
What do you think about?
Yes, it’s possible to use 4 models in a single form. But you have to setup
the
naming of the inputs right coupled with accepts_nested_attributes_for.
The problem is that I need to insert a value in the classification_id
of the join model Categorization.
The table for the join model is automatically enhanced, so when I
create a new Company in the categorizations table the attributes
company_id and category_id are setted.
I want to set also the attribute classification_id of the join table
so I think I can do it only in a before_save callback and not in the
company form.
Hi Marco,
If I understand your question, Do you want to fill in one form many
models.
Am I right?
If your question is this you can use fields_for to apply it.

Hi Marco,

Yes but one of the models is the join model of a has_many :through
relation.
Company has_many :categories, :though => :categorizations
Classification has_many :categorizations
Categorization
belongs_to: company
belongs_to: category
belongs_to: classification
When I create a new Company with a category associated a join model
categorization is magically created with company_id and category_id
setted, ok?
I want be able, in the same form, setting also classification_id and
amount, so that, when the join model is created, it have company_id,
category_id, classification_id and amount all setted
Classification_id is taken from a collection:
