I am following this tutorial here: https://dev.to/nditah/develop-a-simple-python-fastapi-todo-app-in-1-minute-8dg
Most of the requests return a 303 status:
@app.post("/add")
def add(req: Request, title: str = Form(...), db: Session = Depends(get_db)):
new_todo = models.Todo(title=title)
db.add(new_todo)
db.commit()
url = app.url_path_for("home")
return RedirectResponse(url=url, status_code=status.HTTP_303_SEE_OTHER)
@app.get("/update/{todo_id}")
def add(req: Request, todo_id: int, db: Session = Depends(get_db)):
todo = db.query(models.Todo).filter(models.Todo.id == todo_id).first()
todo.complete = not todo.complete
db.commit()
url = app.url_path_for("home")
return RedirectResponse(url=url, status_code=status.HTTP_303_SEE_OTHER)
@app.get("/delete/{todo_id}")
def add(req: Request, todo_id: int, db: Session = Depends(get_db)):
todo = db.query(models.Todo).filter(models.Todo.id == todo_id).first()
db.delete(todo)
db.commit()
url = app.url_path_for("home")
return RedirectResponse(url=url, status_code=status.HTTP_303_SEE_OTHER)
I understand that 303 is a redirect status code, but can anyone explain to me why it would be used in this case? Wouldn't it make more sense to use a status code 200? When I tried to update the status code to:
@app.post("/add")
def add(req: Request, title: str = Form(...), db: Session = Depends(get_db)):
new_todo = models.Todo(title=title)
db.add(new_todo)
db.commit()
url = app.url_path_for("home")
return RedirectResponse(url=url, status_code=status.HTTP_200_OK)
This doesn't work and when I add or update a todo it just takes me to a new empty page. Does anyone have any advice on how I would be able to get status 200 responses instead of 303? The 303 works perfect, but I am not sure I understand the reasoning behind it. Would anyone be able to explain that too?
