Do time consumption of query set matter in django?
i want to know do function model_name.objects.Filter takes the more time then the model.objects.get ? as we all see that the filter gives you the queryset but the get method gives you the single object but having queryset is not equal to having all the object even after having queryset if i select single object by slicing(without loop) or using get method to select the object i tryed to get time difference but it takes soo less time that i can't see from time import time def f1(): t0 = time() # Used filter print("Execution time of f1: {}".format(time()-t0)) def f2(): t0 = time() # Used Get print("Execution time of f2: {}".format(time()-t0)) can someone show me the difference or which is better even i think that get is better but how? -
Why isn't Django Memcached activity being logged?
I'm trying to use Memcached as my main cache for a Django project. However, when I enter some data into my cache to ensure that it's working properly, nothing is being logged into my log file. Here are my Django settings: # settings.py CACHES = { 'default': { 'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache', 'LOCATION': '127.0.0.1:11211', } } CACHE_MIDDLEWARE_ALIAS = 'default' CACHE_MIDDLEWARE_SECONDS = 300 CACHE_MIDDLEWARE_KEY_PREFIX = '' MIDDLEWARE_CLASSES = ( 'django.middleware.cache.UpdateCacheMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', 'django.middleware.security.SecurityMiddleware', 'django.middleware.cache.FetchFromCacheMiddleware', ) Here is my Memcached configuration: # /etc/memcached.conf -d logfile /var/log/memcached.log -vv -m 64 -p 11211 -u memcache -l 127.0.0.1 I created the logfile /var/log/memcached.log and gave it owner 'memcache', group 'adm' and permissions 0644.

Can a Websocket message from the server be spoofed?
I am creating a multiplayer game where users have the option to move up/down/left/right. When a user makes a movement, this movement is sent to the (websocket) server so the opponent can see where the other user is. I'm wondering if these messages that contain user movements can be spoofed? If so, I will have to think of a new method. Thanks in advance -

Django website is loading slow on Heroku, and it is not because of QuerySets
Have website that is running on simple generic Class-Based Views. First I thought - the QuerySets are the issue but since all my queries are lower than 8ms, that is not the issue. Locally the website is running fast under - 200/300ms with all images and everything. When I have pushed it to Heroku it was slow. In the inspect chrome bar - it shows 1 straight line for 1-2 seconds and then loading the rest - it waits 1-2 seconds and then it loads. So I have started to break down the process and came to 1 conclusion - removed the DB and it started loading very fast like 100ms - when I have plugged in the Postgres DB - instantly went to slow mode. Have installed Django-Toolbar as well to see what is going on. Here are the results. I have even tried to put DB and app on higher tiers just to see and no difference. So what I did is as well created simple view Test - with 3 images that I see the images are not causing it and load it - takes 1-2secs to start loading as well - removing DB - loads very … -

Pydub write to buffer Django and Cloudinary
I'm using pydub to slice audio. My use case is that users send long audios (.wav files) from which I only want the first 3 seconds. The .wav files come from a web client to a Django Rest Framework backend, I read (intercept the request) those files and take only the first 3 seconds. Everything works till that point with the following code: # load audio audio_data = request.data.get('sample') audio_pydub = AudioSegment.from_wav(audio_data) # Shorten audio audio_pydub_shortened = audio_pydub[:seconds_to_take] audio_pydub_shortened.duration_seconds But then I want to write the resulting file into the request data, so the request can follow it's flow, so I'm trying to do (without success): resulting_audio = audio_pydub_shortened.export(None, 'wav') request.data['sample'] = resulting_audio.read() super(request) Where resulting_audio is a TemporaryFileWrapper. The error is that the file is deleted from the request as resulting_audio.read() seems to be empty. -

Django: migrating one manytomany field to another manytomany field
I need to migrate some data from class A to class B class A contains a m2m field that, say, links to auth.User This is simply migrating data over, so I add those fields from class A into class B and created migration file. I then loop through all class A objects and assign those fields for each object into class B. When it gets to the m2m field, I run into TypeError: 'ManyRelatedManager' object is not iterable class A(object): something = CharField(blehbleh) something_else = CharField(blehbleh) thing_to_migrate = models.ManyToManyField('auth.User', related_name='some_name', blank=True) class_b = models.ForeignKey('class_B_path', related_name='some_name', on_delete=models.SET_NULL) # so A.class_b gets me class B class B(object): already_exist_field = CharField(blehbleh) thing_I_want_to_migrate_here = models.ManyToManyField('auth.User', related_name='some_other_name', blank=True) related_name needs to be unique, so I set a new name there. When I modify the migration script first the def def migrate_lpinvite_to_invite(apps, schema_editor): ClassA = apps.get_model('appname', 'A') for obj in ClassA.objects.all(): obj.class_B.thing_I_want_to_migrate_here = obj.thing_to_migrate obj.save() then actual runmigration operations = [ migrations.AddField( model_name='B', name='thing_I_want_to_migrate_here', field=models.ManyToManyField(blank=True, related_name='some_other_name', to=settings.AUTH_USER_MODEL), migrations.RunPython(migrate_to_B) ] And I got the error listed above.

Need help designing Django models (tracking changes over time)
I'd like to be able to track how much time a cluster of news articles can be seen inside and RSS feed, and how much time the news articles inside thoses clusters can be seen as well. To this end, I'm scrapping the RSS feed every 15min, I store the clusters inside a table, and I store the articles they contain inside another table. Here is a glimpse of the structure of the RSS feed ("item" would be a cluster of articles, and "news_item" an article): <channel> <title>Channel title</title> <description>Recent articls</description> <link>https:blabla</link> <atom:link href='' rel='self' type='application/rss+xml'/> <item> <title>Basic title</title> <ha:data1>50000</ha:data1> <description>basic description</description> <link>https://mylink</link> <pubDate>Mon, 29 Jul 2019 00:00:00 +0200</pubDate> <ha:data2>https:alink</ha:data2> <he:news_item> <he:news_item_title>SUB ITEM TITLE</he:news_item_title> <he:news_item_snippet>SUB ITEM SNIPPET</ht:news_item_snippet> </he:news_item> <he:news_item> <he:news_item_title>...</he:news_item_title> <he:news_item_snippet>...</he:news_item_snippet> </he:news_item> </item> As a cluster can have several articles, and knowing there is a chance that an article could be seen inside several clusters, I believe a many-to-many relationship is involved.

how do I get a django apps variable to the root app
I have a wait screen that will redirect you to the page specified when the page loads. I put the waitscreen in the main app so it could access the main root url conf to redirect the pages. But, the app that is calling the waitscreen can't pass the redirect variable to teh template because it is not in the same app. heres a hierarchy for better understanding mysite mysite templates mysite wait_screen.html --need to pass the redirect var up here urls.py views.py app1 views.py --this has the redirect variable in it here is my waitscreen in the mysite, it redirects in JS // Redirect var redirect_to = "/{{redirect_to}}"; -- the {{}} is the var used for redirecting window.location.replace(redirect_to); console.log(redirect_to) -- all I am getting right now is the '/' here is the views.py in app1 def wait_screen(request): redirect_to = request.GET.get("redirect_to", "") . --here is the variable context = {'redirect_to': redirect_to} --ps. are these even needed now vvv return render(request, 'mysite/mysite/wait_screen.html', context) -
