Hi folks, I couldn't find this neither in documentation or former posts.
I'm sorry if it has been mentioned already.
I'm trying to achieve this using Postgres and Sequel:
create index my_index_name on my_table ((meta_data->>'meta_data_key'))
This creates a btree index on a Jsonb column called *meta_data* looking for
internal json keys with the name *meta_data_key. *So, on Sequel migration
I'm trying things like:
Sequel.migration do
change do
alter_table :my_table do
add_column :meta_data, "Jsonb"
add_index "((meta_data->>score))".to_sym
end
end
end
The problem is on the `add_index "((meta_data->>score))".to_sym` line. I
keep getting a *PG::UndefinedColumn: ERROR: column "(meta_data->>score)"
does not exist.*
I've also tried several variations like:
`add_index "meta_data->>score"
`add_index :meta_data->>score
`add_index "(meta_data->>score)"
Does anyone know to properly do this?
Thanks in advance!
