Django URL dispatcher - it calls the same view to the different URL(regular expression)
Hello thank you very much for reading my question post. I have different url path patterns in urlpatterns, but Django URL dispatcher(re-path) calls the same view( views.selected_verb) for the different URL expressed by Regular expression. These urls call the same view(views.selected_verb) http://127.0.0.1:8000/arabic/verbs/%D9%83%D8%A7%D9%86/ http://127.0.0.1:8000/arabic/verbs/%D9%83%D8%A7%D9%86/quiz/ Would love to know how to fix it(calls different views) here is urlpatterns urlpatterns = [ path('', views.index, name='index'), path('verbs', views.verbs, name='verbs'), re_path(r'^verbs/(?P<verb>.+)/$', views.selected_verb, name='selected_verb'), re_path(r'^verbs/(?P<verb>.+)/quiz/$', views.quiz, name='quiz'), ] Thank you very much again! -

500 error when uploading files with Filer to S3 using boto3 and django-storages on Elastic Beanstalk
I receive the following 500 http error when attempting to upload a file via the django-cms Filer admin in my app deployed to Elastic Beanstalk: In browser console, coming from fileuploader.min.js:26: POST http://app-staging.us-east-1.elasticbeanstalk.com/admin/filer/clipboard/operations/upload/1/?qqfile=example.jpg 500 (Internal Server Error) I am using django-cms (and therefore easy-thumbnails), django-storages and boto3. When deploying, the collectstatic command in my .ebextensions config file works great, and the files are all nicely stored in the S3 bucket in /staging/static/.

Django model.py models.ForeignKey()
I am a newbie on Django framework and a bit confused on the models. When a "class" in the model.py, can I just understand it as "table" in database? For example, in the code below, "Test", "Contact", and "Tag" are all tables in the database used by Django? from django.db import models class Test(models.Model): name = models.CharField(max_length=20) class Contact(models.Model): name = models.CharField(max_length=200) age = models.IntegerField(default=0) email = models.EmailField() def __unicode__(self): return self.name class Tag(models.Model): contact = models.ForeignKey(Contact) name = models.CharField(max_length=50) def __unicode__(self): return self.name In the class Tag, it is using models.ForeignKey(Contact), based on my understanding, the foreignkey should be established on one specific column of a table, but why the ForeignKey is establish on a table directly, i.e. Table Contact? Any guidance is highly appreciated. -

load balancing in django

Day of Week Query with Timezone Enabled
Consider a simple DB Schema: Table XYZ: filter_datetime: DateTime field (With Timezone enabled) Now, if I want to find all XYZ rows where filter_datetime occurred on "Monday", that is doable if I ignore the Timezone. However, how do I query, if I do not want to ignore timezone information? Also, specifically for my case, I can make sure that filter_datetime would have the same timezone. However, once the table is populated, users should be able to query according to different Timezones and get correct results. (That is a user in UTC+6:00 would have different rows when he tries to get Monday rows as opposed to a user who have timezone in UTC-6:00) Bonus (Not really needed for me to accept the answer): Is it possible via Django ORM? -
Django - proper way to implement threaded comments
I'm currently developing a blog site using Django. I'm still a Django rookie so bare with me. My site will allow users to comment on any of my blog posts and also reply to each other and will be displayed using a 'threaded comments' structure (I haven't started user functionality yet, just comments). I've got the threaded comments to work properly using django-mptt (at least, for now), but I have NO CLUE if the route or steps I'm taking are in the right direction. Almost all the tutorials I've gone through only scratch the surface when it comes to comments and don't talk about threaded comments in django. I want some experienced/professional advice on what I might be doing wrong and what I could be doing better. Last thing I want is to find out there was a much more acceptable way of going about, after hours of work put in.
