In this lab, you will learn how to perform Create Read Update and Delete (CRUD) processes on a MongoDB database. You will first create a collection and then add documents to it. You will practice reading data from the collection and making corrections to the data.
You will need basic Python programming skills for this lab:
– [Certified Associate in Python Programming Certification](https://acloud.guru/overview/8169e8e7-91a7-4d92-b278-4dd08c787dc6)
Learning Objectives
Successfully complete this lab by achieving the following learning objectives:
- Create DB Connection (connect_db.py)
First, you will need to connect to the database. To do this, create a function named
get_database_connectionin the connect_db.py file. This function will return a client object that can be used to access the database.- Populate Collection (populate_data.py)
With the connection created, populate a new collection in the
read_data_from_dbfunction using thecontract_listprovided in the file.- Read Data (read_data.py)
Now you can read the documents from the collection using the
read_data_from_dbfunction. The skeleton also has code to compare the read data to a known good copy and print it to the screen.- Update and Delete (update_data.py)
With the data successfully loaded, you are now ready to make some updates:
- First, delete the document with the incorrect page number in the
delete_data_from_dbfunction. - Then, resolve the failed assertation
due date not updated correctlyby updating the due date in theupdate_datafunction.
- First, delete the document with the incorrect page number in the
