python - Upgrading django from 1.9 to 1.11: reverse accessor clash -


models.py:

class societe(models.model):     ...  class client(societe):     ...     class meta(societe.meta):         proxy = true  class fournisseur(societe):     ...     class meta(societe.meta):         proxy = true  class commande(models.model):     client = models.foreignkey(client, related_name='commandes')     fournisseur = models.foreignkey(fournisseur, related_name='commandes')

this works in django 1.9, in 1.11, error:

commande.client: (fields.e304) reverse accessor 'commande.client' clashes reverse accessor 'commande.fournisseur'. commande.client: (fields.e305) reverse query name 'commande.client' clashes reverse query name 'commande.fournisseur'. commande.fournisseur: (fields.e304) reverse accessor 'commande.fournisseur' clashes reverse accessor 'commande.client'. commande.fournisseur: (fields.e305) reverse query name 'commande.fournisseur' clashes reverse query name 'commande.client'.

django seems consider client , fournisseur same model. dont't want change related names, idea how fix problem?

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
