QUESTION
I'm new to FastAPI, I have implemented everything but when it comes to testing the API I can't override a dependency.
Here is my code:
test_controller.py
...ANSWER
Answered 2022-Apr-12 at 05:59I think you should put your app.dependency_overrides
inside the function with @pytest.fixture
. Try to put it inside your client()
.
QUESTION
i am pretty sure if i am doing the build in my local with this current docker file, i can run the image
...ANSWER
Answered 2022-Apr-07 at 14:55You're using --file backend/copium_api/Dockerfile
but all build context is relative to .
meaning your files are not copied as you expect.
You have 3 options:
cd
into the directory before building (and changeCOPY backend/copium_api/requirements.txt .
toCOPY requirements.txt .
)- Change your second
COPY
statement toCOPY backend/copium_api/* .
- Change your entrypoint to
python -m backend/copium_api/server

I am creating an API using fastAPI, which receives a form from a HTML page, treats it (requiring a few moments) and returns a message saying this task is complete. The way my API is built is:
...ANSWER
Answered 2022-Apr-04 at 19:05You would need to use a Javascript interface/library, such as Fetch API, to make an asynchronous HTTP request. Also, you should use Templates to render and return a TemplateResponse
, instead of FileResponse
, as shown in your code. Example below:

QUESTION
I have encountered strange redirect behaviour after returning a RedirectResponse object
events.py
...ANSWER
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 simple server that listens on port 8000
and all it does is to return the name of the files inside a directory in this format:
ANSWER
Answered 2022-Mar-09 at 20:20The problem is coming from your client code. As you defined your state, initially file
is undefined
. And since fetching data is asynchronous, sometimes the render happens before you get the data. One way to solve this issue is to initiate your state like this:
QUESTION
I just made a Fast api and deployed it using docker containers. But when running 127.0.0.1:5000 on browser it has empty response. Main.py file:
...ANSWER
Answered 2022-Feb-28 at 01:11You should also link the exposed port to an open port on the host machine when running the container.
QUESTION
I am working on a project that has a FastAPI back end with a React Frontend. When calling the back end via fetch
I sometimes get the following:
ANSWER
Answered 2022-Feb-24 at 10:19When a server side error occurs (a response code of 5xx), the CORS middleware doesn't get to add their headers since the request is effectively terminated, making it impossible for the browser to read the response.
For your second problem, you should use a separate session for each invocation of your API. The reference guide has an example of how to do this:
QUESTION
I am running into an error when trying to run my container where it is saying it can't find a module while trying to import. Specifically:
ModuleNotFoundError: No module named 'sentry_sdk'
The following is my DockerFile which is a multistage build, it seems to install all the packages according to the console output.
...ANSWER
Answered 2022-Feb-18 at 17:05OK I figured it out and now I feel dumb.
The issue was indeed related to the venv, basically, uvicorn is installed on the base image but not in my pyproject.toml. So poetry didn't install it in the venv. When I started the app in the Dockerfile using CMD it couldn't find uvicorn in the venv so went to the base install and ran from there. When I added uvicorn to the venv it all worked fine.
