Instance Method Details

#serializer_for(object, serializer: nil) ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Note:

This never bubbles up the object’s namespace, only the caller’s namespace.

Bubbles up the namespace until we find a matching serializer.

Examples:

namespace: Api::V1::Admin::Detailed
serializer: Chat::User

# This method will attempt to find a serializer defined in the following order:

# - Api::V1::Admin::Detailed::Chat::UserSerializer
# - Api::V1::Admin::Chat::UserSerializer
# - Api::V1::Chat::UserSerializer
# - Api::Chat::UserSerializer
# - Chat::UserSerializer
