Great job on your code! However, there are a few improvements that need to be made. Please handle potential exceptions to provide user-friendly messages and avoid multiple saves on the same object for efficiency. Keep going! 🚀

This line of code can raise a MovieSession.DoesNotExist exception if the session with the provided id doesn't exist. It's a good practice to handle this exception and provide a user-friendly message. You can do this by using Django's get_object_or_404() function or by adding a try/except block around this line.

You're calling the save() method twice for the order object which is against the DRY principle. You should only call save() once after you've finished modifying the object. Here's how you can refactor your code:
python
order = Order.objects.create(username=username)
if date:
order.created_at = date
order.save()

Similarly, you're calling save() method twice for the ticket object. You don't need to call save() after create() because create() already saves the object in the database. You can safely remove this line.

According to the checklist, you should use get_user_model() instead of directly importing User from db.models. This is a best practice in Django to avoid potential issues with custom user models.

According to the checklist, you should use double quotes in your code. Please, replace single quotes with double quotes.

It's better to use get_user_model() function instead of directly using User. This is a good practice in Django.

Great job on the pull request! Most of the code looks good, and there are no critical issues that would impact functionality or security. There are, however, a few minor points that you could improve upon. Keep up the good work, and remember to consider the suggestions provided. Happy coding! 😊

Code Style: It's recommended to use get_user_model() instead of directly referring to the User model. This is considered a best practice in Django because it allows for flexibility if the user model is swapped out in the future.

Code Style: The class Meta is defined before all attributes of the Order model. According to the checklist, the class Meta should be defined after all attributes. Please move class Meta after the user attribute.

The variable name genres_ids may be a bit misleading. It seems to suggest that you are expecting multiple ids for a single genre. Consider renaming it to genre_ids to make it clear that it refers to ids of multiple genres.

The same issue with the variable name actors_ids. Consider renaming it to actor_ids.

Instead of manually creating a list of dictionaries, you could use Django's values() method. This method returns a QuerySet that returns dictionaries, rather than model instances, when used as an iterable. Each dictionary represents an object, with the keys corresponding to the attribute names of model objects.

Code style issue: It's better to use get_user_model().objects.create_user() instead of Order.objects.create(username=username). This is a best practice.

Don't Repeat Yourself: You are calling the save() method twice. It's better to call it once after all changes are made.

Code style issue: Use one style of quotes in your code. You have used both single and double quotes. Double quotes are preferable.

There was a problem hiding this comment.
According to the checklist, you should call the save() method only once if possible. In the create_user function, you are calling set_password method which internally calls save(). It's better to set the password directly while creating the user. Here is an example: user = get_user_model().objects.create_user(username=username, password=password).
