**FastAPI** prendra le modèle Pydantic à partir de là, générera le `JSON Schema` et le placera au bon endroit.
Le bon endroit est :
* Dans la clé `content`, qui a pour valeur un autre objet {!../../../docs_src/additional_responses/tutorial001.py!}
**FastAPI** will take the Pydantic model from there, generate the `JSON Schema`, and put it in the correct place.
The correct place is:
* In the key `content`, that has as value another JSO from fastapi import FastAPI

QUESTION
ANSWER
Answered 2022-Mar-23 at 22:19SQLAlchemy does not return a dictionary, which is what pydantic expects by default. You can configure your model to also support loading from standard orm parameters (i.e. attributes on the object instead of dictionary lookups):
QUESTION
I have a multilang FastApi connected to MongoDB. My document in MongoDB is duplicated in the two languages available and structured this way (simplified example):
...ANSWER
Answered 2022-Feb-22 at 08:00There are 2 parts to the answer (API call and data structure)
for the API call, you could separate them into 2 routes like /api/v1/fr/... and /api/v1/en/... (separating ressource representation!) and play with fastapi.APIRouter to declare the same route twice but changing for each route the validation schema by the one you want to use.
you could start by declaring a common BaseModel as an ABC as well as an ABCEnum.

I have encountered strange redirect behaviour after returning a RedirectResponse object

Answered 2022-Jan-19 at 20:22When you want to redirect to a GET after a POST, the best practice is to redirect with a 303 status code, so just update your code to:

QUESTION
I have a csv file that i want to render in a fastAPI app. I only managed to render te csv in json format like following:
...ANSWER
Answered 2022-Feb-23 at 09:03The below shows four different ways to return the data from a csv file.
Option 1 is to get the file data as JSON and parse it into a dict. You can optionally change the orientation of the data using the orient parameter in the to_json() method.
- Update 1: Using to_dict() method might be a better option, as there is no need for parsing the
JSONstring. - Update 2: When using to_dict() method and returning the
dict, FastAPI, behind the scenes, automatically converts that return value intoJSON, using thejsonable_encoder. Thus, to avoid that extra work, you could still use to_json() method, but instead of parsing theJSONstring, put it in aResponseand return it directly, as shown in the example below.
Option 2 is to return the data in string form, using to_string() method.
Option 3 is to return the data as an HTML table, using to_html() method.
Option 4 is to return the file as is using FastAPI's FileResponse.
QUESTION
I am using FastAPI with Pydantic.
My problem - I need to raise ValueError using Pydantic
...ANSWER
Answered 2021-Aug-25 at 04:48If you're not raising an HTTPException then normally any other uncaught exception will generate a 500 response (an Internal Server Error). If your intent is to respond with some other custom error message and HTTP status when raising a particular exception - say, ValueError - then you can use add a global exception handler to your app:
QUESTION
TLDR I want to kill a subprocess like top while it is still running
I am using Fastapi to run a command on input. For example if I enter top my program runs the command but since it does not return, at the moment I have to use a time delay then kill/terminate it. However I want to be able to kill it while it is still running. However at the moment it won't run my kill command until the time runs out.
Here is the current code for running a process:
ANSWER
Answered 2022-Jan-06 at 13:00It's because subprocess.run is blocking itself - you need to run shell command in background e.g. if you have asnycio loop already on, you could use subprocesses

ANSWER
Answered 2021-Dec-19 at 11:55Let's start by explaining what you are doing wrong.
FastAPI's TestClient is just a re-export of Starlette's TestClient which is a subclass of requests.Session. The requests library's post method has the following signature:
QUESTION
I have an issue that I can't wrap my head around. I have an API service built using FastAPI, and when I try to call any endpoint from another Python script on my local machine, the response takes 2+ seconds. When I send the same request through cURL or the built-in Swagger docs, the response is nearly instant.
The entire server script is this:
...ANSWER
Answered 2021-Nov-27 at 22:15Try using „127.0.0.1“ instead of „localhost“ to refer to your machine. I once had a similar issue, where the DNS lookup for localhost on windows was taking half a second or longer. I don‘t have an explanation for that behaviour, but at least one other person on SO seems to have struggled with it as well…
QUESTION
I am using nsidnev/fastapi-realworld-example-app.
I need to apply transaction logic to this project.
In one API, I am calling a lot of methods from repositories and doing updating, inserting and deleting operations in many tables. If there is an exception in any of these operations, how can I roll back changes? (Or if everything is correct then commit.)
...ANSWER
Answered 2021-Nov-20 at 02:01nsidnev/fastapi-realworld-example-app is using asyncpg.
There are two ways to use Transactions.

No vulnerabilities reported
Install fastapi
Now modify the file main.py to receive a body from a PUT request. Declare the body using standard Python types, thanks to Pydantic. The server should reload automatically (because you added --reload to the uvicorn command above).
