Why Django rest framework is not saving data but returns 200 ok code

Question

I have successfully send a post request to deployed(in Heroku) Django rest API from react axios but the data is not saved in my database. I use MongoDB(Djongo) as a databse. Let me show you the code I have used.

                )

        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

I used React Axios for post request and here is the code

const handleUploadFile = (e) => {
    let myfile = file;

    let formData = new FormData();
    formData.append("file", myfile);
    formData.append("client", company_name);
    formData.append("business_process", business);
    http({
      url: "https://cyberminds-backend.herokuapp.com/api/business_process/upload-business-impact-excel-by-superuser",
      method: "POST",
      mode: "cors",
      data: formData,
      headers: { "Content-Type": "multipart/form-data" },
    }).then(
      (response) => {
        alert("File uploaded Sesscessfullyyyyy");
      },
      (err) => {
        console.log(err);
      }
    );
  };

Here is the request from chrome dev tools.

How can I actually save the post data into my database?

Thanks

Answer 1

the reason u are uploading files and not saving, is because u did not setup staticfiles in your settings. Add these in your settings underneath static url:

STATIC_ROOT = os.path.join(BASE_DIR, 'static')
STATICFILES_DIRS = [
    os.path.join(BASE_DIR, 'staticfiles/static/')
]

and the run python manage.py collectstatics on your server
