What's the best way to reload python query module during development?

I'm working on my first query module for Memgraph. I'm trying to find the best approach.

I have a query module that depends on a local submodule (firstone):

import firstone
import mgp
import importlib

@mgp.read_proc
def procedure(context...):
    importlib.reload(firstone)
    firstone.call()

If I get it correctly, if firstone module changes, the procedure is still using the previous code. How can I reload the Python query module during development?

Solution

  • You can use the use mg.load to load or reload the given module. The correct syntax is CALL mg.load("py_example");. After loading the module, all dependent Python's submodules that are imported will also be reloaded. The official documentation can be found on Memgraph site.
