RoR-嵌套属性-表链

Question

I understood the option:

accepts_nested_attributes_for

When I need to manipulate 2 tables trough 1 form, or 1 controller I can use that.

Before I try something that I didn't find answear let me know if I will break something in rails philosophy.

I have a chain of tables in my database:

TableA
  has_many :TableB
end

TableB
  belongs_to :TableA
  has_many:TableC
end

TableC
  belongs_to :TableB
  has_many :TableD
end

Adn so on... It stops somewhere.

Let me try an scenario with 5 tables in this pattern. If I use the first table, in the context above it's that TableA, can I manipulate all 5 tables at the same time? I mean, at the same controller? Same form, using that nested attributes => A accepts B, B accepts C, and so on? Am I wrong thinking that way?

Thanks, you've been so nice!

*pattern example: country has many states, states has many cities, cities has many...

Answer 1

Yes you can do that. That could leave you with a very complicated form for your users though.
