Any reason I'd be seeing this in my rails 6 app?
NameError: uninitialized constant #<Class:0x00007ff1e9c351f8>::Leafy

My Model has this:

class TeamContact < ApplicationRecord
  include Leafy::Mixin::Schema[:active_record]
 ...
end

We use Leafy with ActiveRecord and Postgres. Our leafy_data type is jsonb. leafy_fields and leafy_values work fine.

But sometimes we need to use data from leafy_data field directly in SQL queries. Because of serialization to JSON text before saving to the database Postgres thinks it is a string and can't parse it or convert to JSON type. So the problem is that we can't use leafy_data in SQL queries.

I think, one of the possible solutions is to modify FieldValueCollection dump and load to not use json serialization for ActiveRecord json/jsonb type fields. What do you think about this?

Leafy::FieldValueCollection

def self.dump(field_values_collection, json_serialization = true)
  collection = field_values_collection
                 .map { |field_value| [field_value.id, field_value.raw] }
                 .to_h

  json_serialization ? JSON.dump(collection) : collection
end

def self.load(leafy_fields, data, json_serialization = true)
  Leafy::FieldValueCollection.new(
      leafy_fields,
      json_serialization ? JSON.load(data) : data
  )
end

And call it like that:

Leafy::Mixin::ActiveRecord::Fields::InstanceMethods

def leafy_field_values
  :Leafy::FieldValueCollection.load(leafy_fields, leafy_data || "{}", activerecord_json_column?)
end

Using Rails 6, ActiveRecord, and Postgres

After retrieving an existing model from the database, I updated the model to have a "custom" field:

tc.update(
  leafy_fields_attributes: [
    { name: "hs_city", type: :string}
    ]  
) 

Although, upon trying to pull the values (which I'd expect to be nil) I get an undefined method 'leafy_values' error. So no getter...
So I thought perhaps I had to assign values (even though that shouldn't be the case)

tc.leafy_values ={ "hs_city": 'Gallatin'}

But this threw basically the same error undefined method 'leafy_values=' so no setter...

But indeed the object did store the "custom" field:

tc.leafy_fields
=> #<Leafy::Schema:0x00007fcc0875f400 @fields=[#<Leafy::Field:0x00007fcc0875f3b0 @id="hs_city-eed709f9-fea3-47ad-97e1-5e81ef800a66", @metadata={}, @name="hs_city", @type="string">]>

Am I missing something from the Read me? Or perhaps another initializer/config?
