Does anyone have any experience with multiplexing JsonWebsocketConsumers in Django Channels?

moldy mcspud thats what i am doing but i recently had to go from every 200 requests to 40 requests, a few views are just eating to much memory, i still want to understand WHY memory is never released

mcspud what kind of high volume process? how did you optimize it? where and how is it served?

fission6: well, look at what the views are *doing*

constructing thousands of model objects? can you use .values()?

gonna review that mold^ and possibly iterator

franklyrosalind: i'm using that guy's code as base, i'm almost there

BUT i still dont get why uwsgi just either stays the same or grows in memory use

that should be part of django stack, i'm going to sugest that, as optgroup is a html5 element

When I use annotate with Case to add a field that depends on a state of other objects that have foreign key to current list of objects, if there are multiple objects of the foreign relationship, I get my original list with duplicates

and I can't use .distinct('id') cause I want the list sorted.

And sorting it in python is very slow

any suggestions?

i have written a custom widget for my tags, based on the MultipleHiddenWidget https://dpaste.de/N3NF#L13 and render it in the browser with https://sean.is/poppin/tags which works awesome. however, if i clear out all tags, the return value of https://dpaste.de/N3NF#L13 is empty string '' but this doesn't get saved to the modelfield (tags = models.TextField(_('Tags'), blank=True, default='')). Instead the previous value is being kept. What do i

have to do in order to get the empty string get saved to the DB? all non-hidden widgets work fine?

Hello guys - i wonder if anyone could help me (or suggest a proper google searchterm). I am trying to create a relation between 2 models, ManyToOne, but with an extra: the remote model should have access to the former via 2 different reverse relations (maybe using custom managers for each reverse-relation). Can someone give me a hint on how to accomplish this? (an example kind of representing what i want

to accomplish: http://dpaste.com/12751PC ) Thanks in advance

hey - trying to update the information of a model with a foreign key through a rest put/patch call, however, only some of the data gets saved

the method im writing is PacientUpdateSerializer, rest provided for extra info on the model

any help aprpeciated

@moldy: nice one :D but it would not support creating querysets like (fictive Store!) Store.objects.filter(pizzas__veggie_toppings__name__startwith="toma")

with third party libraries that require you to instantiate a client before making a request to something like an API, are those constructions typically expensive? I ask because I'm reviewing some code that instantiates the client each time a (fairly low-level) function is called and wondering if it makes sense to refactor so that the client behaves more singletonish

im guessing i have to get the related "uporabnik" class and update it simultaneously

just not sure how to go about doing that
