Replace bash scripts with iPython ...scripts?

I recently discovered the joy of using iPython for all of my bash needs, but want to fully transition form using the terminal. Is there a way I can execute bash statements in a python script using the iPython "!sudo ___" syntax or similar? Thanks!

How do we pass a variable to include tag?

I have a bunch of html files with files names as id.html. I want to include one of the files in another html file depending on the value of id received from the route. I want to do something like this:

{% include 'files/{{ id }}.html' %}

How do I achieve this?

Is Jupyter Notebooks unreliable or am I good to hand in this project?

I have a final project for a class that I have used jupyter notebooks to complete. There are a lot of graphs and such in the notebook. When I get into the notebook and use "Run All" and run all of the cells it works, but if I go back in and run an individual cell it will crash.

Also, last night it worked perfectly fine when I did run all, but then this morning I did it and some of the cells crashed and I had to fix them.

It feels like sometimes things work in Jupyter notebooks and sometimes they don't, it is honestly really frustrating and makes me glad that I am taught more application development vs data science, because I can't imagine having to use Jupyter notebooks all the time.

I believe they crash because I change variables later on in the code, and when I run the individual cell again the variables have changed so it crashes, but I am not positive since sometimes it works and sometimes it does not.

If I run all and have all of the cells properly working and displaying their graphs will it appear that way when my professor looks at

Large plots in Jupyter notebooks (in Windows)

I am doing some mapping/GIS work with Python, which leads to large plots. However, I can't seem to enlarge the plot area - at least vertically. I can't change the backend, as the only ones I seem to have available are backend_agg, backend_nbagg, backend_webagg_core. So: how do I install other backends? Or - how do I enlarge the plot area so that the entire plot is displayed; that is, without scroll bars? Thanks!

Django Templates + React

I currently have a project that is a django-rest-api backend with a react/redux front end. I recently implemented "django-wiki" into my project and customized the cosmetics, this project uses django templates. Has anyone ever used django templates on one portion of the website and a different front end framework like react for another portion? I'm having difficulties syncing the login, in the react portion I use local storage to save the jwt for access and i'm not sure where to implement that on the django end so it flows to both portions of the project.

Didn't get the job, code review please

Hey all,

Recently I applied for a junior backend position and was sent this assignment:

>Create a REST API for cars. It should contain accounts, CarBrand, UserCar, and CarModels. Each user has to be extended by default Django abstract class and should contain a few more columns (for your choice). Each car object contains relations to the user and CarBrand. Each CarModel contains relation to CarBrand. It is all your decision how you will distribute models to different apps. Please make the API URLs with filters (custom typed). All models should be with soft delete.
>
>Models fields:
CarBrand [name, created_at, deleted_at\]
CarModel [car_brand, name, created_at, update_at\]
UserCar [user, car_brand, car_model, first_reg, odometer, created_at, deleted_at\]
>
>Auth:
Please extend the default Django user class and add some custom fields. Create login, register functionality. User default Django permission classes.

I sent this code:

https://github.com/todortoshev/cars-api

https://carsapp.pythonanywhere.com/cars/all/

"User default Django permission classes." - I assumed this applies to django.contrib.auth in INSTALLED_APPS, so I didn't add permissions in settings.REST_FRAMEWORK.

The assignment also says CarModel has to have a field 'update_at', but doesn't mention 'deleted_at', so I left in 'update_at' and added 'deleted_at', as all models must have soft delete.

How can I make my test so they don't use other tests?

I am testing APIs using APITestCase. For example, I do a test to make a post request to create an instance in the model A, model B has model A as foreign key. If I execute my tests, it gave me an error in the second test saying that model A does not exist, so the easy solution would be to call the test that creates the instance in model A so model B can use it to execute the test but model A would execute two times. I don't think this is correct because if model C needs an instance of model A and B, I would need to add the test where model A and B are created, but that gave me an error because the test of model A would execute 3 times. So what do I do? I create the instance of model A assuming that test will create an instance of model B, but again, I don't think this is correct because it will make a snowball of tests.

class test_A(APITestCase):

def test_post_request(self):

SQLAlchemy classes from a pre-existing schema

I have .SQL files of the schema and I need to convert them into SQLAlchemy classes (not trying to create all table classes manually). Can I convert the schema into an sqlite db and then use that db to automap into SQLAlchemy table classes? Is there a better way directly using a schema ?
