To retrieve all documents from a MongoDB collection using Python and the
mongoengine library, you can make use of the
Document.objects() method. Here’s an example:
from mongoengine import connect, Document, StringField # Connect to the MongoDB database connect('my_database') # Define a sample document class MyDocument(Document): name = StringField() # Retrieve all documents from the collection documents = MyDocument.objects() # Print the documents for document in documents: print(document.name)
In this example, we import the necessary modules and connect to the MongoDB database using the
connect() function from
mongoengine. Next, we define a sample document class
MyDocument with a
name field of type
To retrieve all documents from the collection, we use the
MyDocument.objects() method, which returns a
QuerySet representing all the documents in the collection. We can then iterate over the
QuerySet and access the document fields as needed. In this example, we simply print the
name field of each document.
Note that you will need to replace
'my_database' with the actual name of your MongoDB database. Additionally, you may need to define other fields and configurations in your document class based on your specific requirements.
Make sure to install the
mongoengine library if you haven’t already (
pip install mongoengine).
