Installation

pip install mongoengine_serialize

Example:

Your mongoengine schema

class Users(Document):
    avatar_url = URLField(required=True)
    first_name = StringField(required=True)
    last_name = StringField(required=True)
    email = StringField(required=True)
    password = StringField(required=True)
    created_at = DateTimeField(default=utc_now)
    posts = ReferenceField('Posts')
class Posts(Document):
    content = StringField(required=True)
    comments = ListField(ReferenceField('Comments'))

from mongoengine_serialize import Serialize

user = Users.objects(first_name=’Hello’).first()
serialized_user = Serialize(user).jsonify()

#### Changing data attributes
> Alter data by using alter_after_serialize_attributes function

from mongoengine_serialize import Serialize

UserSerializer(Serialize):

def alter_after_serialize_attributes(self, serialized, raw):
    if "avatar_url" in serialized:
        serialized['avatar_url'] = "http://" + serialized['avatar_ur']
    elif "posts" in collection:
        serialized["posts"] = Serialize(raw).jsonify()
    return serialized

user = Users.objects(first_name=’Hello’).first()
serialized_user = UserSerializer(user).jsonify()

> alter_after_serialize_attributes is called each attribute of the collection.
> the best practice to use it is when you needed a 2nd to 3rd to deapest tier of ObjectId connected to your parent collection.
#### Exclude attributes
> exclude_attribute is called before set_attributes
> it helps on filtering your dictionary before returning

Serialize(user).exclude(‘password’, ‘created_at’).jsonify()
```
