Hi, thanks for the response but I would like to clarify that I have to check columns coming from two models, I am not sure how it can be implemented using validators only, but as of now i am trying a brute force approach

Hi people. I am working on a project that deals with enrollment activities such as generation of subject offerings and such. I have a model called Offering which has a has_many relationship with the model Schedules. Basically, an offering has many schedules. In order to check for conflicts the room_id which is an attribute of the model Offering has to be unique along with the attributes time and days in Schedule, any suggestion on how should i do this, without using a tedious brute force approach?
