PyMongo
Djongo

Djongo generates complex, error free, aggregation queries automatically.

It takes the query on the top and automatically generates the pymongo query document as the output.

Security and Integrity Checks 

def script_injection(value):
  if value.find('<script>') != -1:
    raise ValidationError(_('Script injection in %(value)s'),
                          params={'value': value})

class Entry(models.Model):
  homepage = models.URLField(validators=[URLValidator,
                                         script_injection])

Djongo performs checks on data fields before they are saved to the database.

Define custom validators or use builtin validators to check the data. Validation is triggered prior to writing to the database.

Running integrity checks and field value validators ensures protect from garbage data.

Djongo

Djongo Djongo is a unified approach to database interfacing. It is an extension to the
Django ORM framework but maps python objects to MongoDB documents.

Constructing queries using Djongo is much easier compared to writing lengthy Pymongo query documents. Storing raw JSON emitted by the frontend directly into the database is scary. Djongo ensures that only clean data gets through.

You no longer need to use the shell to inspect your data. By using the Admin package, you can access and modify data directly from the browser. Djongo includes handy UI elements that help represent MongoDB documents on the browser.
