Mongodb data schema validation errors - mongodb

Question

In my flask app I am trying to insert data into a mongodb database and validating the data, but I keep getting validation errors and I can seem to be able to locate why this is the case. I am new to mongodb. Note the validation rules are applied when I create the users collection like this:
try:
collection = d.list_collections()
if collection is not None:
if os.environ.get("FLASK_ENV") == 'development':
d.users.drop()
d.emails.drop()
d.create_collection(name="users", validator=users.user, validationLevel='strict', validationAction='error')
d.create_collection(name="emails", validator=emails.email, validationLevel='strict', validationAction='error')
except OperationFailure as e:
app.logger.error(f'Validation setup error: {e}')
Here is my validation python file (users.py):
user = {
"bsonType": "object",
"additionalProperties": False,
"required": [
"username", "first_name", "last_name",
"password", "email", "pin",
"phone_number", "firebase_uid", "groups",
"created_at"
],
"properties": {
"username": {
"bsonType": "string",
"description": "must be a string and is required"
},
"first_name": {
"bsonType": "string",
"description": "must be a string and is required"
},
"last_name": {
"bsonType": "string",
"description": "must be a string and is required"
},
"password": {
"bsonType": "binData",
"description": "must be a hashed string and is required"
},
"email": {
"bsonType": "string",
"pattern": "^[a-z0-9]+[\\._]?[a-z0-9]+[#]\\w+[.]\\w{2,3}$",
"description": "must be a string and is required"
},
"pin": {
"bsonType": "int",
"description": "must be a number and is required"
},
"phone_number": {
"bsonType": "string",
"pattern": "^\\+234[^0](?:\\d{9})",
"description": "must be a string and is required"
},
"firebase_uid": {
"bsonType": "string",
"description": "User firebase registration uid"
},
"groups": {
"bsonType": "object",
"required": ["owned", "belong"],
"properties": {
"owned": {
"bsonType": "array",
"uniqueItems": True,
"items": {
"grp_id": {
"bsonType": "objectId",
"description": "Must be an objectId"
}
}
},
"belong": {
"bsonType": "array",
"uniqueItems": True,
"items": {
"grp_id": {
"bsonType": "objectId",
"description": "Must be an objectId"
},
}
}
}
},
"created_at": {
"bsonType": "date",
"description": "The date and time user was created"
}
}
}
And this is the data being inserted:
{
"username": "joshua223",
"first_name": "Joy",
"last_name": "Kudosen",
"password": "password",
"email": "joshua22#gmail.com",
"pin": 1245,
"phone_number": "[phone]",
"firebase_uid": "XttdyeAOGxewe3434renuRTjCX0KsHXxod92",
"groups": {
"owned": [
],
"belong": [
]
}
}
And this is the error:
[2022-05-19 01:30:28 +0100] [420098] [ERROR] Validation error: Document failed validation, full error: {'index': 0, 'code': 121, 'errInfo': {'failingDocumentId': ObjectId('62858fa4e0decf4b6664dc6e'), 'details': {'operatorName': '$and', 'clausesNotSatisfied': [{'index': 0, 'details': {'operatorName': '$eq', 'specifiedAs': {'bsonType': 'object'}, 'reason': 'field was missing'}}, ...
Please note I am inserting the "created_at" field using a python Datime.now(timezone.utc)" function and it isn't in the original data. This is how I am inserting:
try:
current_app.logger.info("register_user Function called ...")
# Check for duplicate user registration using
# email and phone_number
# print(f'email: {dict(dumps(json_string))}')
if is_valid_data(json_string["email"], mtype="email") \
and is_valid_data(json_string["phone_number"], mtype="phone_number") \
and is_valid_data(json_string["username"], mtype="username"):
if get_user_by_property("email", json_string["email"], confirm=True) \
or get_user_by_property("phone_number", json_string["phone_number"], confirm=True) \
or get_user_by_property("username", json_string["username"], confirm=True):
return False
else:
now = datetime.now(timezone.utc)
print(f"DateTime: {now}") # TODO: Remove
# print(f'Password: {user_info["password"]}')
user_info = {
"username": json_string["username"],
"first_name": json_string["first_name"],
"last_name": json_string["last_name"],
"password": hash_user_input(json_string["password"]),
"email": json_string["email"],
"pin": json_string["pin"],
"phone_number": json_string["phone_number"],
"firebase_uid": json_string["firebase_uid"],
"groups": json_string["groups"],
"created_at": now
}
try:
print("Insert_one about to be called ...") # TODO: Remove
u = db.users.insert_one(user_info).inserted_id
except Exception as i:
return current_app.logger.error(f'Validation error: {i}')
