letsencrypt standalone certification not showing up on GET request
I was able to create certifications under the path /etc/letsencrypt/{{mywebdomain}}/ and set under my server where the ssl_cert and ssl_cert_key absolute pathfile locations for my nginx server. When I run the command sudo nginx -t I receive a successful configuration output and the nginx server is running in the reverse proxy for Django without any problems. But when I access the root of my website on my chrome browser, I'm receiving the "http://website.com" instead of "https://website.com". Please point me in the right direction if anyone was able to correctly encrypt their domain content with gunicorn-django-nginx configuration. My website snippet conf: upstream app_server { unix:/home/me/Documents/masterdomain/src/portfolio_revamp.sock; } server { client_max_body_size 4M; listen 80; listen [::]:80; listen 443 ssl; listen [::]:443 ssl; listen www.mysite.com:80; server_name example.com www.example.com; http://example.com; ssl_certificate /etc/letsencrypt/live/mysite.com/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/mysite.com/privkey.pem; root /home/akeem/Documents/SpencerMaster/src; index templates/home.html templates/main.html; location / { proxy_pass http://unix:/home/me/Documents/masterdomain/src/portfolio_revamp.sock; alias /home/me/Documents/master/templates/home.html; } location ~ /.well-known { allow all; } location /static { autoindex on; alias /home/me/Documents/masterdomain/static; } location /media { autoindex on; alias /home/me/Documents/masterdomain/media; } } I'm running a xenial ubuntu 16.04 server if that makes a difference. -

Django - 2 URLS with same regex, but different variables and views
I have the following urls: url(r'^(?P<college_name>\w+)/$', views.detail, name="detail"), url(r'^(?P<photographer_username>\w+)/$', views.photographer, name="photographer"), It works when I do /college_name url, but when typing in a photographer such as website.com/johnsmith it only searches the first url pattern and then stops. If I put the photographer url pattern first, it works for photographers and not for colleges. How do I fix it so it works for both? -
Order of ManytoMany field in model changed when one object is replaced
I am trying to build a publication database for researchers. So my database has model classes Paper, Author and Journal. Journal is a foreign key to Paper while Author is a ManytoMany key to Paper. The model definition is thus: from django.db import models from django import forms from django.forms import ModelForm, Textarea # Create your models here. class Journal(models.Model): name = models.CharField(max_length = 100) organization = models.CharField(max_length = 100, blank = True) def __unicode__(self): return self.name class Author(models.Model): first_name = models.CharField(max_length = 20, blank = True) last_name = models.CharField(max_length = 20, blank = True) middle_name = models.CharField(max_length = 20, blank = True) full_name = models.CharField(max_length = 50) email = models.EmailField(blank = True) def __unicode__(self): return self.full_name class Paper(models.Model): paper_title = models.CharField(max_length=200) paper_year = models.IntegerField(blank = True, null = True) paper_volume = models.CharField(max_length = 100, blank = True, null = True) paper_number = models.CharField(max_length = 100, blank = True, null = True) paper_pages = models.CharField(max_length = 100, blank = True, null = True) paper_month = models.CharField(max_length = 15, blank = True, null = True) paper_doi = models.CharField(max_length = 50, blank = True, null = True) paper_abstract = models.TextField(blank = True, null = True) paper_keywords = models.TextField(blank = True, null = … -
Multiple Django apps under the same site
I am thinking of creating a content delivery web application using Django with a MySQL database, and after reading the docs a bit I noted that it is possible to create multiple apps in the same project/site directory. It may or may not apply to what I want to do, but I was wondering what the motivation behind this architecture is. Why would I want multiple web apps in one site? For example, Youtube was built around the Django framework, but the entire experience works seamlessly as one application? Is Youtube actually one large web application, or does the project use many applications packaged as one product? If so, why would that be a better option? -

django case sensitive url changes the case automatically
I am using the following regex for my urls. url(r'^(?P<slug>[a-zA-Z0-9_-]+)/$',short_url, name='short_url') the URL is suppose to be case sensitive because I setup it that way in mysql for the slug field. when I do mysql query it does exactly what it is suppose to be. but when I change one letter like 'Y' http://127.0.0.1:8000/p/Y9j4oL/ to 'y' , django redirects to the above url again. http://127.0.0.1:8000/p/y9j4oL/ why is this happening ? and how to fix it? -

Django remove duplicates in queryset and access their list of foreign key
Here is my model: class Item(models.Model): title = models.TextField() class Storage(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) item = models.ForeignKey(Item, on_delete=models.CASCADE) rating = models.IntegerField(blank=True, null=True) review = models.CharField(max_length=1500, blank=True, null=True) class SocialProfile(models.Model): user = models.OneToOneField(User, unique=True) follows = models.ManyToManyField('self', related_name='followed_by', symmetrical=False) Say there are 4 users A,B,C,D. User A follows only B and C. I'm trying to do a view that when log in as User A. Show a list of items that B and C has (duplicates show only one time). And under each item, show their summary and ratings. I have something here: (user = User A here) //get a list of users that User A follows followings = user.socialprofile.follows.all() //get B and C's saved item, eliminate the duplicates context['following_saved_article'] = Item.objects.filter(storage__user__in=followings.values('user')).distinct() //get a flat list of all users A follows context['followings'] = list(followings.values_list('user', flat=True).order_by('user')) Then in the template: {% for item in following_saved_item %} {{ item.title }} {% for x in item.storage_set.all %} {% if x.user_id in followings %} {{ x.review }} {{ x.rating }} {% endif %} {% endfor %} {% endfor %} This seems too redundant, and I will have a pretty hard time if I want to sort reviews by user rating. Any suggestions? Thanks -

Alternative Admin in Django

How can I convert a python object to string using the context?
I am trying to render object instances in django templates the way forms do it. So somewhere in a view an object instance gets created: my_object = MyObject() and passed to the template in the context: context['my_object'] = myobject. When the template is processed, the __str__() method of MyObject is called to create a string to be filled in. For MyObject it looks something like this: def __str__(self): """ Render template """ return mark_safe( render_to_string(self.template, {'options': self.options}) ) Since the object's template would like to add code to the CSS and JS blocks using sekizai, I need the rendering context. Is there a way (e.g., using an different method) to get this context? -

Provide default django login view under a url argument
What I want to lay out is a design that works similar to the following. I have a urls.py definition like: url(r'^(?P<slug>[-\w]+)/login/$', auth_views.login, name='customer_login'), url(r'^(?P<slug>[-\w]+)/logout/$', auth_views.logout, {'next_page': 'customer_login'}), where the slug identifies some client and I want to provide a login view for each client. What I am basically struggling with at the moment is the fact that the default django login view can't handle the additional kwarg slug. And I also want all the redirect_to links from the login & logout view to be based on that slug value. My question: Is there some solution for this problem? Is the above layout a bad design and should it be handled differently? -
