I'm trying to order by a jsonb column in rails using:
Stat.order("data ->'likes'->'followed_by' ASC")
I keep getting this error returned.
PG::UndefinedFunction: ERROR: could not identify an ordering operator for type json
I can't figure out is it my formatting? The followed_by attribute is a int.
Thank you!
I'm not certain but according to http://www.postgresql.org/docs/9.3/static/functions-json.html
->
"Get JSON object field" ->>
"Get JSON object field as text" So perhaps activerecord can't sort the field
but can sort the text
?
Try: Stat.order("data ->'likes'->>'followed_by' ASC")
