Hi, I seem to be missing an image, which is preventing the Snake BnB app from running in PyCharm.

This is in the 'Demo:Getting started with the application / demo code' lesson in the Modeling data in document databases module.

Not sure what image I need or where to retrieve it, thanks. Thanks -Ian

Not sure if that qualifies as an issue, but I noticed that the command selection in the starter_code.

The show_commands method shows 'L' as being for login in, but the switch case lists it as 'list_cage' instead.

def show_commands():
    print('What action would you like to take:')
    print('[C]reate an account')
    print('[L]ogin to your account')
    print('[R]egister a cage')
    print('[U]pdate cage availability')
    print('[V]iew your bookings')
    print('Change [M]ode (guest or host)')
    print('e[X]it app')
    print('[?] Help (this info)')
    print()

with switch(action) as s:
    s.case('c', create_account)
    s.case('a', log_into_account)
    s.case('l', list_cages)
    s.case('r', register_cage)
    s.case('u', update_availability)
    s.case('v', view_bookings)
    s.case('m', lambda: 'change_mode')
    s.case(['x', 'bye', 'exit', 'exit()'], exit_app)
    s.case('?', show_commands)
    s.case('', lambda: None)
    s.default(unknown_command)```

I am trying to run your snakebnb course but it won't load past section 4 lecture nine due to this error:

ile "/home/jbrandes/mongodb-quickstart-course/src/snake_bnb/src/program.py", line 1, in
from colorama import Fore
ModuleNotFoundError: No module named 'colorama'

First of all, thanks for the free course on Udemy!

However, in section 5, video 16 you connect to the database, but in the github-files there is apparently no database to connect with.
At least I haven't found anything.
I've installed Robo 3T (formerly RoboMongo) to mimic what you're doing in the video, but where the database comes from is incomprehensible for me.

Thanks in advance for your help!

As i start to go through the tutorial i download the code. and see its the complete code i.e. final snake bnb.
it would be helpful if i can code as the tutorial progress. just having the base structure will be nice on which we can build and complete the code as the session progresses.

Hi Mike,

Just starting to work through this after hearing about it on your podcast. The recent move of the requirements.txt file to the src directory creates a mismatch with the video. The student is left wondering whether to run the python -m venv command in snake_bnb or in the src subdirectory (where the requirements.txt is now). Well, I wondered.

Also I'm using an anaconda python3 dist, and I got

python3 -m venv .env --copies
Error: Command '['..../mongodb-quickstart-course/src/snake_bnb/.env/bin/python3', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 127.

What worked for me was
python3 -m venv --without-pip .env --copies
This created the .env directory in snake_bnb alongside src. Hope this is as intended.

Howdy and thanks a ton for this course! Ok, Q:

In the video here: https://training.talkpython.fm/player/course/mongodb-python-quickstart-mongoengine/lecture/100303

👉 Integration DBs vs application DBs, 1m13s, you say "an integration database isn't a great idea for relational databases."
Is that what you meant? After the explanation a few seconds prior about the model being enforced by the applications and they could get out of sync, potentially getting to data corruption, I thought you were talking about document dbs, not relational dbs.

If a relational DB forces model at the DB level, won't that lead to less potential of data corruption?

Dear Mike,
i'm doing this course. I'have this issue when i try to update the availability of a cage. Can you help me?
