Write Data to MongoDB - Django MongoDB Backend v5.2

You can use your application's models to update documents stored in the sample_mflix database. To update documents, enter the Python interactive shell and call create, update, and delete functions on your model objects.

From your project's root directory, run the following command to enter the Python shell:

From your Python shell, run the following code to import your models and the module for creating a datetime object:

from sample_mflix.models import Movie, Award, Viewerfrom django.utils import timezonefrom datetime import datetime

Run the following code to create an Movie object that stores data about a movie titled "Minari", including its awards in an Award object:

movie_awards = Award(wins=122, nominations=245, text="Won 1 Oscar")movie = Movie.objects.create(    title="Minari",    plot="A Korean-American family moves to an Arkansas farm in search of their own American Dream",    runtime=217,    released=timezone.make_aware(datetime(2020, 1, 26)),    awards=movie_awards,    genres=["Drama", "Comedy"])

The Movie object created in the previous step has inaccurate data: the runtime value is 217, but the correct runtime value is 117.

Run the following code to update the object's runtime value:

movie.runtime = 117movie.save()

You can also use your Viewer model to insert documents into the sample_mflix.users collection. Run the following code to create a Viewer object that stores data about a movie viewer named "Abigail Carter":

viewer = Viewer.objects.create(    name="Abigail Carter",    email="abigail.carter@fakegmail.com")

One movie viewer named "Alliser Thorne" no longer uses the movie streaming site. To remove this viewer's corresponding document from the database, run the following code:

old_viewer = Viewer.objects.filter(name="Alliser Thorne").first()old_viewer.delete()

Exit the Python shell by running the following code:

Then, start your server by running the following command from your project's root directory:

python manage.py runserver

To ensure that you inserted a Movie object into the database, visit the http://127.0.0.1:8000/recent_movies/ URL. You can see a list of five movies in the sample_mflix.movies database, with your new movie listed at the top.

Then, ensure that you inserted a Viewer object into the database by visiting the http://127.0.0.1:8000/viewers_list/ URL. You can see a list of ten viewer names in the sample_mflix.users database, with your new viewer listed at the top. Ensure that the viewer named "Alliser Thorne", deleted in a previous step, does not appear in this list.

After completing these steps, you have inserted and edited documents in the sample_mflix sample database.
