Plesk Django .py files showing in browser. How do I make it safe?
I create some django websites using Plesk Onyx. My problem is If I go to domainname.com/appname/settings.py or domainname.com/manage.py url i see everything in ".py" file. My folder permissions 755, file permissions is 644. The problem is solved when I set the file permissions to 640 or 600. Is there a shortcut in django related to this vulnerability? or do I need to change individual file permissions? I'm looking for an easy way. I don't know, maybe by adding a little code in django I can prevent these files from appearing. Im using python 3.6 - Django 2.2.3 - Plesk Onyx - Nginx -
Comparing request.path to a string in Django template
I've been messing around with Django for a bit and I ran into this issue, where the comparison in the if labeled below, returns false, when they're both the same string. If request.path is /test/ then "/{{values|lower}}/" is also /test/ yet they're not equal. Why is this the case? <form class="btn-group btn-group-sm btn-group-toggle btn-block" action="" method="POST"> {% for i in name %} {% csrf_token %} {{ form.as_p }} <input {% cycle name.0 name.1 name.2 name.3 name.4 as values %} // HERE {% if press == values or request.path == "/{{values|lower}}/" %} class="btn btn-outline-dark btn-block m-2 active" {% else %} class="btn btn-outline-dark btn-block m-2" {% endif %} type="Submit" name="{{values}}" value="{{values}}"/> // THESE TWO LINES PRINT THE STRINGS ON PAGE {{request.path}} /{{values|lower}}/ {% endfor %} </form> -
Make some elements of choice array readonly in Django?
I have a model: class myLimit(models.Model): limit = models.PositiveSmallIntegerField(help_text="The upper limit of the number of points that can be used.") TYPES_OF_LIMITS = [('perday','Limit Per Day'),('lifetime', 'Lifetime Limit'),('peruser', 'Per User'),] limit_type = models.CharField(choices=TYPES_OF_LIMITS, max_length=20, default='lifetime') ... I want to know how to disable (or make it read-only) the "peruser" ("Per User") choice/option. The current myLimit acts as a base model for an extended model which sets the default of limit_type to "peruser" and makes the entire thing read-only my using admin model's exclude = ('limit_type',). I set the default in the save() method of the extended model just before calling the super method. The main question remains: How to make a few choices read-only? I have read tutorials on making the entire field read-only, hiding it, and others but haven't figured out a way to make "only some choices" read-only. -

How to display images in a loop

What is the correct method for implementing <mysite.com/some_user> URL routing in Django?
I want my site members to get access to other user's profile pages via URL mysite.com/some_user instead of mysite.com/profiles/some_user, but with every request to another url path, the view function responsible for the user profile page gets executed. I expect Django to stop looking for any other url path when it finds a matching path, this is my base URL configuration: urlpatterns = [ path('', include('events.urls')), path('<str:username>', view_profile) ] and this is the view responsible for /some_user: def view_profile(request,username): try: member = User.objects.get(username=username) member_events = Feed.my_events(member) return render(request,'profile.html',{'member_events':member_events}) except User.DoesNotExist: print('No data') return HttpResponse('No data') now when I send a request to mysite.com/feedstream , despite the page loads correctly the view_profile() gets executed (judging by the No data print on server console) I could not find any guide online maybe because I don't know the exact keywords for the problem, what am I doing wrong? -
Django TypeError: argument must be int or float when trying to access model

How to make user permissions that expire after 24 hours?
I'm creating a service where I give users who pay for access - access for a timed period, i.e. 24 hours. Once they've made a payment. I auto file data into this premium model: class Premium(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) datetime_payment = model.DateTimeField(default=datetime.now, blank=True) order_id = models.CharField(max_length=250, blank=True) has_premium = models.BooleanField(default=False) class Meta: ordering = ['user'] permissions = (("can_access_premium", "Premium Access"),) def __str__(self): return f'{self.user}({self.has_premium})' So I want the user permissions for premium access to end after 24 hours. How can I change a user permissions. They can buy multiple times, so the trigger for this 24-permission is a payment. -

Django and Processing raising: "raise AppRegistryNotReady("Apps aren't loaded yet.")"
I wanted to upload some stuff from DB into google sheets. So i figured I will use processing or multy treading.

User authentication in django : Logging in using api rather than form
I'm using Django, and am looking to have the option to login both using a web page (the standard way) and through a separate client process (for the sake of my testing, using python requests) I've seen another answer about doing an ajax login, but my understanding of this solution is that it would be vulnerable to a CSRF attack, as it's only taking the POSTed username/password. What I'd like to do is request a CSRF token (with a GET call to my custom /auth-api/login view), and then pass this in a POST call along with the username and password. This is what I currently have in views.py from django.middleware import csrf from django.http import JsonResponse def login( request ) : return JsonResponse( { 'csrf_token': csrf.get_token( request ) } ) From Python on the client end, I'm then doing: (I have verify=False here because I am currently using a self-signed SSL certificate for development purposes) result = s.get( "https://<ip_addr>/auth-api/login", verify=False ) csrf_token = json.loads( result.text )['csrf_token'] s.post( "https://<ip_addr>/auth-api/login", verify=False, data={'csrfmiddlewaretoken': csrf_token, 'username': "<username>", 'password': "<password>" }, cookies=result.cookies ) However, the text of the response to this tells me that the CSRF token is missing or incorrect.

Django - QuerySet Index Instead of Loop
Home Page In the picture above, I am trying to find a way to have 6 featured posts from my database appear instead of just six static entities in HTML. Here is the view for the home page: from django.shortcuts import render from singlePost.models import Post # Create your views here. def index(request): queryset = Post.objects.filter(featured=True) context = { 'object_list': queryset } return render(request, 'index.html', context) Here is a little bit of code from the home page HTML (looping through object_list): {% if forloop.counter0 == 0 %} <h3 class="mb-15 mb-sm-5 font-sm-13"><b>{{ obj.title }}</b></h3> {% endif %} My question is: how can I get the indices of object_list so I can just use the first 6 featured Posts? I do not know how to do that, so it is currently looping through all posts and I use an if as seen above to check the current index, but that just seems wrong looping 6 times instead of using indices. The loop would be fine if all the divs were the same, but as you see in the picture, they are not. So, how do I get the indices of a QuerySet? Or are there any better ways to do this then … -

Here's my model which causes the problem: class VotingValuesHistory(models.Model): # id = models.AutoField(primary_key=True, auto_created=True) value1 = models.CharField(max_length=40) value2 = models.CharField(max_length=40) value3 = models.CharField(max_length=40) value4 = models.CharField(max_length=40) value5 = models.CharField(max_length=40) score1 = models.CharField(choices=VOTE_CHOICES, max_length=20) score2 = models.CharField(choices=VOTE_CHOICES, max_length=20) score3 = models.CharField(choices=VOTE_CHOICES, max_length=20) score4 = models.CharField(choices=VOTE_CHOICES, max_length=20) score5 = models.CharField(choices=VOTE_CHOICES, max_length=20) user = models.EmailField(max_length=255) group = models.CharField(max_length=250, default='notingroup') date = models.DateTimeField(auto_now_add=True) and it's also pointing the view where I'm making a query to the objects as: From views.py: v1 = VotingValuesHistory.objects.all().filter() for item in v1: if item.group == groupname: if item.score1 == 'disaster': numscore_disaster += 1 elif item.score1 == 'meh': numscore_meh += 1 else: numscore_helpful += 1 I have tried makemigrations and migrate commands using: heroku run python manage.py makemigrations heroku run python manage.py migrate -
