python - rpyc: difference between root.getmodule("module_name") and manually returning a module reference? -


i want use python module accessible on remote rpyc server only. there difference between following 2 ways of accessing modules on remote machine:


""" on client side: """

  1. my_local_mod_ref = my_rpyc_connection.root.getmodule("remote_module_name")
  2. my_local_mod_ref = my_rpyc_connection.root.a_func_returning_the_module_ref()


""" on server side: """

def exposed_a_func_returning_the_module_ref()     import my_remote_module_name     return my_remote_module_name

if there difference, of 2 alternatives cleaner or preferable?

here implementation of getmodule:

def exposed_getmodule(self, name):     """imports arbitrary module"""     return __import__(name, none, none, "*")

as can see, if module not loaded in server, calling getmodule imports it, , (either way) netref object module returned.

if matches behavior of a_func_returning_the_module_ref(), there's no difference.

i'd guess getmodule provided out-of-the-box, being useful, don't have define (or similar) explicitly in order achieve goal.

sequelize.js - Sequelize: sort by enum cases -

i have model ( article ) field (the name type ) of type enum('source', 'translated') , return 1 article ordered type field. source articles should returned before translated articles. like: article.findone(order: [ { type: [ 'source', 'translated' ] } ]); unfortunately there appears no built-in solution sorting enums. instead have sort by case , couldn't find documentation on how sequelize. what conventional approach here? sorting case hard in sequelize, sort field (the second answer in linked post) should possible: order: sequelize.fn('field', sequelize.col('type'), 'source', 'translated') it's supported mysql far know though
