Minty Command and Query based on DDD

Project description

This “Command and Query” module allows a developer to generate an abstraction around calling commands and queries in a domain model.

Getting started

# In your calling module
from minty_ddd.ddd import (

# Configuration: Set a domain prefix, and add "tests.domain.brewing.service"
dddc = DDDConfiguration()
dddc.domainprefix = "tests.domain"

# Execute a command on the "brewing" domain
cqs = CommandAndQuery()
command = cqs.command(domain="brewing", command="BrewBeer")

# Optionally, create a service factory, which gets propagated through
# the command and query objects
cqs = CommandAndQuery(service_factory=CustomObject())

if command.execute(alcohol_percentage=4):
  print("Executed succesfully")

query = cqs.query(domain="brewing", query="ListBeers")
list_of_beers = query.execute()

# Params can also be pre-set by the command or query function:
query = cqs.query(domain="brewing", query="ListBeers", params={"page": 1})
