Code introduction
This code defines a function that uses the Beanie library to randomly query data from a database based on a specified field. First, a simple Pydantic model is defined, then a Beanie database is created and some sample data is added. Then, a query is generated by randomly selecting a field and value, and the query is executed to return the result.
Technology Stack : The code uses the Beanie library and Pydantic for defining a simple model and handling the database operations. It also uses random module for generating random values for the query.
Code Type : The type of code
Code Difficulty : Advanced
