MongoDB

You can access any database from any file in your project as follows:

from mongofire import MongoDB

db = MongoDB('MyDatabaseName')

Now with db object you can do anything. You can read write, delete update, etc.

Note

The db object contains a mongo object, you can access the original database object of pymongo.

Here is an example of how to do that:

db.mongo # < This is Database object for pymongo

Now suppose we have a collection of users in our mongo database and we need to add a new user to it. You can do this as follows:

from mongofire import MongoDB

db = MongoDB('MyDatabaseName')

db.collection("users").document('my_custom_user_id').set(
    {
        'name': 'Mohamed',
        'age': 20,
    }
)

To understand how document and set method works, check out the MongoDBDocument class.

Now suppose we need to get all users older than 18 years old. You can do this as follows:

from mongofire import MongoDB

db = MongoDB('MyDatabaseName')

query = db.collection('users').where('age', '>', 18)

for user in query.stream():
    print(user.id)
    print(user.data.to_dict())

If you need to understand how collection and queries actually work in MongoFire, check out the MongoDBCollection class
