After lot of test, I finally found something nice.
If you want to use a custom module with a custom name, the best to do is to create a module and giving him the name you want
Tree :
/GLOBALCONFIG
|- /module_manager
|- block1.py
|- block2.py
|- blocX..
- module_version_manager
/block1
|- /v1
|- script1.py
|- /v2
|- script1.py
/block2
|- /v1
|- script2.py
|- /v2
|- script2.py
For that I've made a dir named "GLOBALCONFIG" at the project root that contains a .py manager with this :
from importlib import import_module
import sys
import os
block1 = sys.modules['block1'] = import_module('block1.v1')
block2 = sys.modules['block2'] = import_module('block2.v1')
Using this, i can keep all my import, specifying the version only on the "manager" file, eg :
block1/v1/script1.py :
from GLOBALCONFIG.module_manager.block1 import block2
from block2 import script2
if I put script2 in block2/v2 or /v3 or any, i just have to change with the right version to use for block2 in block1.py manager and code will still work
Moreover, if you want :
block1/v1 using block2/v1
block1/v2 using block2/v2
You can create a dict that refer the module / version in your global config :
module_version_manager.py :
block1_modules_versions = {
'block1.v1': {
'block2':'block2.v1',
}
'block1.v2': {
'block2':'block2.v2',
}
}
block2_modules_versions = {
'block2.v2': {
'block1':'block1.v1',
}
'block2.v2': {
'block1':'block1.v2',
}
}
then, in your block1.py manager :
from GLOBALCONFIG.module_version_manager import block1_modules_versions
from importlib import import_module
import sys
import os
block1 = sys.modules['u1'] = import_module('.'.join(str.rsplit(sys.argv[0], "/")[3:5])) # give me the current version of the current block : block1.vX
block2 = sys.modules['block2'] = import_module(block1_modules_versions['.'.join(str.rsplit(sys.argv[0], "/")[3:5])]['block2']) # give me the block2 to use for the right block1.vX
in block1/v1/script1.py :
import sys
sys.argv[0] = __file__ # [path]/block1/v1/script1 => current path of executed script giving the right folder and import the right modules
from GLOBALCONFIG.module_manager.block1 import block1, block2
block1 => block1/v1
block2 => block2/v1
But here is the magical trick :
in block1/v2/script1.py :
import sys
sys.argv[0] = __file__
from GLOBALCONFIG.module_manager.block1 import block1, block2
block1 => block1/v2
block2 => block2/v2
Different version but exactly the same code
FYI : The sys.argv[0] = file that force the current file path is mandatory for me cause my service start using gunicon wsgi:app that made the default path at [venv]/bin/gunicorn but without this constraint, the GLOBALCONFIG import should nicely work
