It seems need remove duplicates with keep last per column 'game' by DataFrame.drop_duplicates and then if need lists aggregate them by list:

Yes, it is possible to do it. Filtering would be easy with a recursive function, pattern matching and the filterObject() function, but there is a hidden complexity. You are not just filtering but also flattening the object hierarchy. The trick is to do both separately and merge the results.

I'm not a 100% sure why your code throws the given error, my first guess is that the ids sent are actually wrong. Please add a console.log before the .findOneAndUpdate calls, to check whether the correct ids were sent or not.

Other than that there are a couple of things to enhance your code.

The findOneAndUpdate call already updates your documents in the database, so you don't actually need to call .save() after them.

Secondly you don't need to manually cast ids to ObjectIds, mongoose does that automatically for you.

Thirdly you can replace the findOneAndUpdate calls with findByIdAndUpdate and if you're not returning the updated results, you can also leave out the new: true option.

You should also place both these calls in a Promise.all() because they don't depend each other so the request will be answered sooner as the db operations are now running in parallel.

And if data consistency is important to you, you could also use transactions for these operations.

The main function has a strange behavior, trying to call IniApp with a home argument that does not exist. Try to simplify it by calling it once as such: void main() => runApp(IniApp());

You could make it an outer join and then check that there is no record for the outer joined table

This is what plt.figure(constrained_layout=True) is supposed to do. If you want to stretch it further you could do for instance:

You need to add a many to many field related to users in Event, then you can add the user in the view and finally you can do a filter to show the Events like:

First, remove the creator field from the model form
