JSONb with Ruby on Rails

I needed to get something from the database in my job. I tried the current query using PSequel and it gave an error.

SELECT * FROM declarations WHERE data->>'some_data' IS NOT NULL;

The way I got the results was through the console with the following:

bundle exec rails console

declarations_ids = []

Declaration.find_each do |d|
  declarations_ids << d.id unless d.data['some_data'].nil?
end

declarations_ids
# [3523, 262623, 623623, ...N-1]

Now we can solve the problem raised by that field.
