Question

Develop a CRUD class that, when instantiated, provides the following functionality:

A Create method that inserts a document into a specified MongoDB database and collection
- Input -> argument to function will be a set of key/value pairs in the data type acceptable to the MongoDB driver insert API call.
- Return -> “True” if successful insert, else “False”.
A Read method that queries for document(s) from a specified MongoDB database and specified collection
- Input -> arguments to function should be the key/value lookup pair to use with the MongoDB driver find API call.
- Return -> result in cursor if successful, else MongoDB returned error message.
An Update method that queries for and changes document(s) from a specified MongoDB database and specified collection
- Input -> arguments to function should be the key/value lookup pair to use with the MongoDB driver find API call. Last argument to function will be a set of key/value pairs in the data type acceptable to the MongoDB driver insert API call.
- Return -> result in JSON format if successful, else MongoDB returned error message.
A Delete method that queries for and removes document(s) from a specified MongoDB database and specified collection
- Input -> arguments to function should be the key/value lookup pair to use with the MongoDB driver find API call.
- Return -> result in JSON format if successful, else MongoDB returned error message.
I have already completed for Create and Read method. Now only need code in python for the update and delete method.
