There 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.

When 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:

Run a subprocess to return a redirect response from one port to another.

main.py:

The 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 JSON string.
• Update 2: When using to_dict() method and returning the dict, FastAPI, behind the scenes, automatically converts that return value into JSON, using the jsonable_encoder. Thus, to avoid that extra work, you could still use to_json() method, but instead of parsing the JSON string, put it in a Response and 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.

If 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:

It'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

Let'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:

Try 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…

There are two ways to use Transactions.
