Rails Postgres how to query a jsonb column for empty objects?

Question

How do I get all the empty records for a jsonb column with Active Record ?

Are you looking for all rows where the jsonb column is null? Or, are you looking for all rows where the jsonb column is an empty object '{}'? Some example code/sql would help here. — mrwillihog, Jun 8 at 14:24
I am looking for all the rows where the jsonb column is an empty object '{}' . I actually tried Active Record query interface Model.where.not(my_column: {}) — Shani, 2 days ago

You can query for empty objects in a JSONB column using the following syntax:

Model.where("column = '{}'")
