I’m building what should be a simple CRUD app with a Flask backend. Most of my endpoints have the exact same operations:

1. Return a list of items
2. Ingest a list from CSV

The only differentiators being the specific database table to draw from. I want to save time by defining these routes programatically. Something like this:

def define_routes(app):
    ROUTES = {
        '/list1': lambda : handle_list(model1),
        '/list2': lambda : handle_list(model2),
        # ...
    }

    for url in ROUTES:
        app.add_url_rule(url, view_func=ROUTES[url])

def handle_list(dbModel):
    if request.method == 'GET':
        # return the list
    
    if request.method == 'POST':
        # ingest the list

but when I try to run this I get this error: AssertionError: View function mapping is overwriting an existing endpoint function: <lambda>

Why am I getting this error when I use anonymous lambda functions? Is there a way to do what I’m trying to do?
