我在 pg 生产模式下收到此错误,但在 sqlite3 开发模式下工作正常。
ActiveRecord::StatementInvalid in ManagementController#index
PG::Error: ERROR: column "estates.id" must appear in the GROUP BY clause or be used in an aggregate function
LINE 1: SELECT "estates".* FROM "estates" WHERE "estates"."Mgmt" = ...
^
: SELECT "estates".* FROM "estates" WHERE "estates"."Mgmt" = 'Mazzey' GROUP BY user_id
@myestate = Estate.where(:Mgmt => current_user.Company).group(:user_id).all
