Күн бұрын

In this Python video tutorial you will dive into FastAPI, a web framework for developing modern RESTful APIs using Python. FastAPI is built off of Starlette and Pydantic, therefore the performance of FastAPI is off the charts. Pydantic allows type hints to perform data validation and serialization / deserialization of data. FastAPI automatically creates interactive Swagger UI documentation which is perfect for any developer.

awesome tutorial. I wouldn't use a for-loop btw. Rather use something like: # Find the index of the item to delete item_index = next((index for (index, d) in enumerate(books) if d.id == book_id), None) # Check if book exists if item_index is None: raise HTTPException(status_code=404, detail=f"Id {book_id} does not exist") books[item_index] = book return book

I am glad you were able to do your project in time!

Very good tutorial! For PUT (update) and DELETE you can use "for i, x in enumerate(BOOKS):" instead of the counter and then use "i" as the index e.g. del BOOKS[i]. "enumerate" automatically counts for you in a for loop. It's a bit cleaner than using a counter.

Hi Roby, Just a doubt.. Why the same UUID is showing for every item posted. Why do we need to manually change the same? Can't it be uniquely generated?

@codingwithroby Жыл бұрын

That is just what Swagger does. You can change it on each request.

To auto-generate the ID, you can update the id field definition in the class to this: id: UUID = Field(default_factory=uuid4) You also need to import uuid4: from uuid import UUID, uuid4 You will notice when you look at the swagger doc, that 'id' is no longer a required field and the id has been automatically generated in the POST response.

Can you make a SQLModel video with Select where(single, multiple condition), joins, etc???

Hello couple of questions about your course... -Can it teach me how to get requests from commercial APIs and store them to a database? -Does it teach about custom styling the API data on the front end? -Does it teach at least some JavaScript DOM manipulation or event listeners? I'm interested on playing around different public APIs and display them on the browser with custom styling and click events. Thanks

Hey friend! It does not show those things unfortunately. It is 100% focused on getting someone from beginner to advanced topics. It will cover many things about FastAPI (Request Methods, Authentication, Authorization, JWTs, Security, status codes, responses, data validation, and a ton more!) but does not go over too much JavaScript, or how to communicate with different APIs from different applications.

@@codingwithroby Thanks for the response! I guess the better question is can FastAPI in general able to do what I want to do? I'm looking at your other videos and it seems it's possible I just need to stich them together. Or should I just go with another framework?

@@Frangelo90 Oh yeah, FastAPI can definitely do what you want complete!
