Example 1: Dating App Users
Let's say, you are building the base user functionality for a cross-platform dating app.
The product requirements are:
- Unique phone number is required
- Password should be secure, encrypted, hidden from response
- Gender cannot be changed after set
- This product is adult only
- User intro should be brief
Let's transform the requirements into code.
from jsonclasses import jsonclass, types
from jsonclasses_pymongo import pymongo
from jsonclasses_server import api
@api
@pymongo
@jsonclass
class User:
id: str = types.readonly.str.primary.mongoid.required
phone_no: str = types.str.unique.index.match(local_phone_no_regex).required #1
email: str = types.str.match(email_regex)
password: str = types.str.writeonly.length(8, 16).match(secure_password_regex).transform(salt).required #2
nickname: str = types.str.required
gender: str = types.str.writeonce.oneof(['male', 'female']) #3
age: int = types.int.min(18).max(100) #4
intro: str = types.str.truncate(500) #5
created_at: datetime = types.readonly.datetime.tscreated.required
updated_at: datetime = types.readonly.datetime.tsupdated.required
