I can successfully add new student data
@router.post("/",response_description="Student data added into the database")
async def add_student_data(student: StudentSchema= Depends(),file: UploadFile=File(None)):I have made upload file as optional.
class StudentSchema(BaseModel):
fullname:str = Field(...)
email: EmailStr = Field(...)
course_of_study: str = Field(...)
year: int = Field(...,gt=0,lt=9)
gpa: float = Field(..., le= 4.0)
image: Optional[str]For crud operation, I want to upload file if not added previously, replace new one if added or want to left blank"null"
class UpdateStudentModel(BaseModel):
fullname: Optional[str]
email: Optional[EmailStr]
course_of_study : Optional[str]
year : Optional[int]
gpa: Optional[float]
image: Optional[str]In route
@router.put("/{id}")
async def update_student_data(id:str,req:UpdateStudentModel=Depends(),file: UploadFile=File(None)):
print(file)Everytime it prompts error when i left blank (for file upload) during update
Did not find CR at end of boundary (40)In swagger
{
"detail": "There was an error parsing the body"
}
Here is the part of code of update operation
@router.put("/{id}")
async def update_student_data(id:str,req:UpdateStudentModel=Depends(),file: Optional[UploadFile]=File(None)):
print(file)
req={k:v for k ,v in req.dict().items() if v is not None}

@ekundayo-ab Have you looked at https://github.com/tiangolo/full-stack-fastapi-postgresql/tree/master/%7B%7Bcookiecutter.project_slug%7D%7D/backend/app/app for how they do it there? The api routes have just logic to deal with inputs, and some permissions. And then the meat of the logic is separate in crud. I like to have all the routes defined with the definition of the endpoint together, and then logic elsewhere. So you can end up with something like this:
@app.put("/items/{item_id}", response_model=ItemResponse)
async def update_item(item_id: int, item: Item = Body(..., embed=True)):
return crud.item.update_item(id, item)Its still just the routes, but it tells you input / output. So its a bit more friendly when reading the code.

Since I am using middleware decorator for the lambda function to forward the request to path provided, I am not sure how to do it other than passing in the whole Request object from lambda function. Would this be possible?

Hello Here!
a bit of topic question, but I still try it here:
in setup.py i neeed the keras-contrib@https://github.com/keras-team/keras-contrib.git as REQUIRES_INSTALL package.
Everyting works fine when installing with pip -r ..., BUT when tha package is built as wheel, then
ERROR: Could not find a version that satisfies the requirement keras-contrib (from superduperpack==0.3.5) (from versions: none)
ERROR: No matching distribution found for keras-contrib (from superduperpack==0.3.5)Help appreciated!
Do some "strict" type checking yourself and then mypy knows that it had passed that kind of check, and the error will dissapear
@eseglem thank you for replying to me
this is the error
?[33mWARNING?[0m: Detected file change in 'main.py'. Reloading...
email-validator not installed, email fields will be treated as str.
To install, run: pip install email-validator

also yes im using the environment i made but installed there firstly fast api and ran pip list on that environment
Can anyone help me deploy https://github.com/long2ice/fastapi-admin frontend and backend on a single heroku app.
Yarn build is creating the files inside /dist but my fastapi is trying to access "GET /js/app.2e733260.js HTTP/1.1" 404 and getting 404
I did app.mount("/dist", StaticFiles(directory="dist"))
