Prerequisites

• Create db model for the bingo grid #57 and Create db model for interaction between users and bingo grids #58

Issue

• This view needs to fetch all of the challenge information for the currently active bingo grid (probably in the form of an array of length 16)
• Additionally, it needs to fetch the completion status of all these challenges from the GridInteraction model
• There may not exist an instance of the GridInteraction model with the corresponding user and grid id. If so, then an instance should be created
• However, if the user is not logged in, then there is no need to fetch completion statuses or create an instance of the GridInteraction model.
