How to parse json with errors for nested model from Rails in Android?

Question

Java

There is a model

class User 
  has_one :profile
  accepts_nested_attributes_for :profile
end

When we try to update the profile via user.update({ profile_attributes: { ... }) and pass incorrect profile parameters (let's say we didn't specify the name that is stored in the profile), the server returns errors like this:

{
  'errors': {
    'user.profle': {
       'name': [ 'не может быть пустым']
     }
  }
}

Of course, I would like the rail to give such an answer

{
  'errors': {
    'user': {
       'profle': {
         'name': [ 'не может быть пустым']
       }
     }
  }
}

But for this you need to climb into the insides of the framework.
The question is how to parse the first option so that the resulting objects have the same structure as in the second json. Perhaps there is some way to tell the parser that the fields with a dot should be treated as a nested object?

Answer 1

Loop through the resulting data structure and form a new data structure.
I don't understand what the problem is.
