rest-apis-flask-python's Issues

circular dependency section 6

Hi,

In section 6 of your course, you spoke about circular dependency, but I don't understand why.
I try to put 'from db import db' at the top of the app.py file and it work without errors.

Could you explain brieffly, in which case this circular dependency happen ?

thanks,

Mickael

Small typo in the "How To Deploy Python App Using uWSGI And Nginx" guide

The guide is located here.

After it is installed, we can create a virtualenv:

virtualenv venv --python==python3.5

From looking at the virtualenv documentation, I believe it should be a single equals sign in the command.
virtualenv venv --python=python3.5

This is a great guide, thank you!

Item PUT HTTP response - correction proposal

rest-apis-flask-python/section6/resources/item.py

Lines 48 to 60 in 3380640

    
           def put(self, name): 
        
               data = Item.parser.parse_args() 
        
               item = ItemModel.find_by_name(name) 
        
               if item: 
        
                   item.price = data['price'] 
        
               else: 
        
                   item = ItemModel(name, **data) 
        
               item.save_to_db() 
        
               return item.json()

Hi,
In Lec99, the HTTP response of PUT is not fully correctly dealt with. According to this: https://httpwg.org/specs/rfc7231.html, PUT should return 201, when new resource has been created.
(Also, added error handling similarly to the post() method)
So, I think implementation of put() should be appended with the HTTP response code handling, like this:

    def put(self, name):
        data = Item.parser.parse_args()
        item = ItemModel.find_by_name(name)

        # if item with name doesn't exist, we create it
        if item is None:
            item = ItemModel(name, **data)
            http_status_code = 200
        else:
            item.price = data["price"]
            http_status_code = 201

        try:
            item.save_to_db()
        except:
            return {"message": "An error occurred upserting the item."}, 500

        return item.json(), http_status_code

Best,
Csb

ch11 step 1 render.com does not create the tables

Running the app on render.com triggers the following

OperationalError
sqlalchemy.exc.OperationalError: (sqlite3.OperationalError) no such table: stores
[SQL: SELECT stores.id AS stores_id, stores.name AS stores_name
FROM stores]
(Background on this error at: https://sqlalche.me/e/20/e3q8)

Seems like the data.db is not created when running the app

500 error when creating new Item and no Store exists

When testing in Digital Ocean it showed a 500 error when I tried to create a new item with store id 1 without creating a store before sending the request.

Maybe it would be nice to check the existence of a store and show a more informative message.

Also, add to the course a note about this happening.
