CSS Background Image WILL NOT Load
apologies in advance, as I am relatively new to programming. I'm trying to load an image to my page and set it as my background, below is the css and html that I am working with. The CSS page seems to load, as my test font and background colors show up.

Django: sending e-mail with ajax - security issue
I am working with Django and after few tasks that require ajax calls I would like to send an email: $.when($.ajax({ type: "POST", url: "{% url 'check_status' %}, data: {'params':'data'}, }), ).then(function(){ $.ajax({ type: "POST", url: "{% url 'send_email' %}", data: {'email': email} }); }); I have set up CSRF tokens and the requests are post. However, I am concern with that somebody can use my send_email view to send unwanted e-mails. I would like to restrict the view to be used only for this given template/context not eg. from python requests library. Is it even possible? -
Django-star-ratings model and queryset sorting
New to Django and was hoping to get a little help with integrating the django-star-ratings module. As per the README I have the model: class Post(models.Model): date= models.DateTimeField() title = models.CharField(max_length = 140) artist= models.CharField(max_length = 140) ratings = GenericRelation(Rating, related_query_name='foos') and I'm not entirely sure how sorting the queryset works so I plugged url(r'^$', ListView.as_view(queryset=Post.objects.filter(ratings__isnull=False).order_by('ratings__average'), template_name="UploadApp/upload.html")), as a listview into my urls.py to pass the view . My first question is: even after making migrations, the new ratings field is not showing up in my admin. Any ideas on where I've gone wrong? Second question: have I done the listview sorting bit right? Any help is appreciated! -

Revoking tokens using Django rest-framework-jwt
I'm thinking of allowing a user to revoke previously issued tokens (yes, even though they are set to expire in 15 minutes), but did not find any way to do so using DRF-jwt. Right now, I'm considering several options: Hope someone on SO will show me how to do this out-of-the-box ;-) Use the jti field as a counter, and, upon revocation, require jti > last jti. Add user-level salt to the signing procedure, and change it upon revocation Store live tokens in some Redis DB Is any of the above the way to go? -

Print a template with forms and input to PDF in Django
I'm trying to display a template which has multiple Django forms on it (where users can add comments to a specific section). Then, when they hit a submit button, that template and form data is saved as a PDF to a FileField in the model. My initial inclination is to use a button to kick off the POST request, pull the form information out of it, then create a new request to the template with the form initialized to the data that was pulled out in the post request, and just render that as a PDF using reportlabs or something like that. However, I seem to be struggling to implement it in code, any suggestions? I'm using Django 1.10 and Python3. Thanks! -
Django URL regex with variables
Was hoping someone could point me in the right direction with this. I've tried nearly everything I can think of, but I can't seem to get it to work. I've got a set of URLs I'd like to match in Django: www.something.com/django/tabs/ www.something.com/django/tabs/?id=1 Basically, I want to make it so that when you just visit www.something.com/django/tabs/ it takes you to a splash page where you can browse through stuff. When you visit the second URL however, it takes you to a specific page which you can browse to from the first URL. This page is rendered based on an object in the database, which is why the id number is there. I've tried to account for this in the URL regex, but nothing I try seems to work. They all just take me to the main page. This is what I have in urls.py within the main site folder: urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^tabs/', include("tabs.urls")), ] and within urls.py in the app's folder: urlpatterns = [ url(r'\?id=\d+$', tab), url(r'^$', alltabs) ] Would anyone be so kind as to point me in the right direction? Thanks in advance! -
Django ManyToManyField Admin Green button not working
I am using Django 1.8. I have a model named Service and it is defined as below: class Service(models.Model): name = models.TextField(blank=False, null=False) ... categories = models.ManyToManyField(Category) ... In the admin panel, there is a green '+' icon with Categories field. On my local machine, when I click on the button, a popup opens, I add a category and the flow goes back to the previous form. However, on production, when I click on the button, a new page opens in the same browser tab. And after adding the category, the page goes blank. In the browser's javascript console, I am getting the following error: caught ReferenceError: showRelatedObjectPopup is not defined at HTMLAnchorElement.<anonymous> (related-widget-wrapper.js:19) at HTMLDocument.dispatch (jquery.min.js:3) at HTMLDocument.v.handle (jquery.min.js:3) I have run the collectstatic command and the file related-widget-wrapper.js exists on the server. What is going wrong here? TIA. -

How to use dyanamic urls on templates

Django DateTimeField not saved most of the times
In Django 1.8 using pytz==2014.10 I have this weird problem that the datetime field updates appearently on random basis: The model: class Post(models.Model): title = models.CharField(max_length=300, blank=False) created = models.DateTimeField(auto_now_add=True) creator = models.ForeignKey(User, blank=True, null=True) updated = models.DateTimeField(auto_now=True) lastposted = models.DateTimeField(blank=True) #This is problematic And in views: print 'going to update lastposted', post_id, timezone.now() post = Post.objects.get(pk=post_id) post.lastposted = timezone.now() post.save() in the settings I have: USE_TZ = True TIME_ZONE = 'Europe/Berlin' Example print output in terminal: going to update lastposted 270405 2017-02-08 06:55:04.908058+00:00 But in MariaDB, I see the field has not been updated and it maintains the previous value, which is 2017-02-07 17:01:32 I have no issues saving other fields. The strange thing is that sometimes the lastposted is actually updated, but not most of the times. So I'm really confused and appreciate your clues. -

Not able to pass API urls to the REST API app
I have my Django project split into three apps: frontend: You guessed it, the pure frontend. shared_stuff: This is where I've put my models, because I feel they might be shared between apps later on. rest_api: The, well, REST API. All three apps are also registered in settings.py. Now my problem is that the urls meant for rest_api app are also being serviced by the frontend app. Here's what my main urls.py looks like: urlpatterns = [ url(r'^api/v1', include('rest_api.urls')), url(r'^', include('frontend.urls')), ] Am I doing something wrong? Please feel free to ask for more info! -
Django - IntegrityError null value in column "user_id" violates not-null constraint
I am getting an error that is quite weird and I have no clue what could be causing that. I just want to do a simple signup using either Facebook or on-site registration using AllAuth (a third party registration app). Somehow every time I try to register a new user a new ID is created and a new USER_ID as well. But they are not the same (superuser Id = 1 apart), one seems to be always even and the other one odd. It's like two new users are being created at the same time, but one lacks the USER_ID bringing this integrity error. I even tried to DROP my original database to see if it helps, but the issue remained. I'm using Django 1.8 and Python 3.5 It was working fine until I decided to do a little extension to the user module as shown bellow: profiles/models.py from django.conf import settings from django.contrib.auth.models import User from django.db import models from django.db.models.signals import post_save from django.utils.encoding import smart_text UF_CHOICES = ( ('SP', 'SP'), ('RJ', 'RJ'), ) class Profile(models.Model): user = models.OneToOneField(settings.AUTH_USER_MODEL) ACCOUNT_USER_MODEL_USERNAME_FIELD = 'username' ACCOUNT_USER_MODEL_EMAIL_FIELD = 'email' ACCOUNT_USERNAME_REQUIRED = True ACCOUNT_EMAIL_REQUIRED = True ACCOUNT_AUTHENTICATION_METHOD = 'email' uf = models.CharField( max_length …
