Query through a join table question

[Dave Castellano]

Hi,

I am trying to do the following database query (ie find all question
id's with the selected minisection id):

minisection_questions = Question.where(minisection_id:
minisection_id).pluck(:id)

I have a question table, a minisection table, and a
minisections_questions join table.

Question model - has_and_belongs_to_many :minisections
Minisection model - has_and_belongs_to_many :questions

I get the following error:
PGError: ERROR: column questions.minisection_id does not exist
LINE 1: SELECT id FROM "questions" WHERE "questions"."minisection_i...
^
: SELECT id FROM "questions" WHERE "questions"."minisection_id" = 2

Try Minisection.find(minisection_id).questions.pluck(:id)
