How to write model in custom EVE route

I am experimenting a bit with EVE and am now faced with the question of how to manipulate data in custom created endpoints. Example: I need a POST "user" method where I can intercept the data, hash the password and then save the new user.

For this purpose I would like to overwrite or extend the existing POST method. My attempt:

@app.route('/users', methods=['POST'])
def create_user():
    user = app.data.driver.db['user']
    print(request.json)
    username = request.json.get('username')
    password = request.json.get('password')
    if username is None or password is None:
        abort(400)  # arguments are missing
    if user.find({ 'username': username}) is not None:
        abort(400)  # user is existing
    => hash password
    => save user with hashed password

Unfortunately, overwriting the POST method created by my users model like this does not work either.

Thanks to gcws hint, here is my resulting code for a POST user request in EVE with flask_bcrypt:

...
from flask import request    
from flask_bcrypt import Bcrypt

...

bcrypt = Bcrypt()


def pre_user_post_callback(request):
    print('A POST on "user" was just performed!')

    pw_hash = bcrypt.generate_password_hash(request.json["password"], 12)
    del request.json["password"]
    request.json["password_hash"] = pw_hash.decode()

    print(bcrypt.check_password_hash(request.json["password_hash"] , '12345')) #  True if requested pw is 12345



app.on_pre_POST_user += pre_user_post_callback

You need to use an event hook for that, more specifically, on_insert_users_hook where you can modify the item before insert into database. See the documentation and example here (https://docs.python-eve.org/en/stable/features.html#insert-events).
