MongoEngine - Filters

The objects attribute is a QuerySet manager. It creates and returns a QuerySet when accessed. A query can be subjected to filter with the help of field names as keyword arguments. For example, from above products collection, to print details of document with name of product as ‘TV’, we use Name as keyword argument.

for product in products.objects(Name= TV ):
print ( ID: ,product.ProductID,  Name: ,product.Name,  Price: ,product.price)

You can use filter method of QuerySet object to apply filter to query. Following code snippet also returns product details with name=’TV’.

qset=products.objects
for product in qset.filter(Name= TV ):
   print ( ID: ,product.ProductID,  Name: ,product.Name,  Price: ,product.price)
