What does Import Error: Symbol not found: _PQencryptPasswordConn mean and how do I fix it?
I am trying to execute 'flask run' in the Downloads directory where my Flask_App resides. My Flask_App is 'applications.py'. When I execute 'flask run' in the development environment I am getting a URL. Once I paste the URL into Safari, I get this error. ImportError: dlopen(/Users/dhruvaiyer/anaconda3/lib/python3.7/site-packages/psycopg2/_psycopg.cpython-37m-darwin.so, 2): Symbol not found: _PQencryptPasswordConn Referenced from: /Users/dhruvaiyer/anaconda3/lib/python3.7/site-packages/psycopg2/_psycopg.cpython-37m-darwin.so Expected in: /usr/lib/libpq.5.6.dylib in /Users/dhruvaiyer/anaconda3/lib/python3.7/site-packages/psycopg2/_psycopg.cpython-37m-darwin.so I am using a MacOSX High Sierra. My PostgreSQL is version 11. My python is updated to version 3.7. And pip is upgraded and psycopg is on version 2.8.3. I have tried running 'flask run' on various directories and tried moving 'applications.py' into different libraries and directories that I am currently on. I have tried using sudo but I realise that I don't know the password. In the past I force-created another admin account when I accidentally removed admin status on my admin account...don't know if this has affected sudo or not but its not accepting my current admin password. I had an issue with installing psycopg2 as well but resolved that by re-downloading PostgreSQL 11. I have successfully installed SQLAlchemy and Flask-Session as well using pip. This is my code for 'applications.py' import os from flask import Flask, session from … -
Django-taggit how to modify to have same tag added by different user
I am trying to modify django-taggit to allow the same tag to be added by separate users. I have so modified django-taggit Model so that it has user and team_id values added when user adds tag. The goal is to allow different teams to have their own separate sets of tags. Teams may edit or delete their own tags and that should not affect other teams. Question: Where in the django-taggit code does it look for duplicate tag values and then not add them but instead refer to the existing tag? `apps.py` `forms.py` `managers.py` `models.py` `utils.py` `views.py` My modified django-taggit Model code is below. from django.contrib.contenttypes.fields import GenericForeignKey from django.contrib.contenttypes.models import ContentType from django.db import IntegrityError, models, router, transaction from django.utils.text import slugify from django.utils.translation import gettext, gettext_lazy as _ from django.conf import settings from crum import get_current_user try: from unidecode import unidecode except ImportError: def unidecode(tag): return tag class TagBase(models.Model): name = models.CharField(verbose_name=_("Name"), unique=True, max_length=100) slug = models.SlugField(verbose_name=_("Slug"), unique=True, max_length=100) ### MODIFIED: added team and user to model team_id = models.CharField(max_length=10, blank=False, null=False) user = models.ForeignKey(settings.AUTH_USER_MODEL, null=True, on_delete=models.DO_NOTHING) def __str__(self): return self.name def __gt__(self, other): return self.name.lower() > other.name.lower() def __lt__(self, other): return self.name.lower() < other.name.lower() class Meta: abstract … -
How do I store device and receive Auth token from my Django Webapp
I just started developing on xcode and I am currently trying to allow access with a user and password through to my Django Webapp. The django webapp already has an api-auth route. I am trying to find a direction to go. So far I have tried the normal /login/ route that I have with an HTTP POST. (Which I would usually do with just the webapp) I am assuming its not the same with my xcode app. def post(self, request): # TODO: User can get token even though user is not email verified # this should work for traderocket & flow track etc serializer = AuthTokenSerializer(data=request.data) serializer.is_valid(raise_exception=True) user = serializer.validated_data['user'] if request.current_site == user.site: token, created = Token.objects.get_or_create(user=user) return Response({'token': token.key}) return Response({'token': None}) This is what my route for the auth looks like. This part of the project was not worked on by myself and I am a bit new to xcode. Is it just the normal http request I have been doing? How do I store the token? I tried to find these answers but perhaps I am looking at the wrong terms/concepts. -
How to sort a result of objects shown after a search with keyword in Django
Actually i have a working code but the issue that i am facing is how to sort the result of the queryset based on multiple rule. This is my models.py : class Node(MPTTModel): parent = TreeForeignKey('self', on_delete=models.CASCADE, blank=True, null=True, related_name='children') name = models.TextField(blank=True, null=True)` viewed_by = models.ManyToManyField(CustomUser, related_name='viewed_by', blank=True) bookmarked_by = models.ManyToManyField(CustomUser, related_name='bookmarked_by', blank=True) thumbs_up = models.ManyToManyField(CustomUser, related_name='thumbs_up', blank=True) In my views.py i have managed to queryset the database and show all the results based on all matching words, but the missing point here is that i have managed only to sort the result by the number of bookmarks. For i.e : i have this two objects : Object 1 : name = How to use django forms ? Object 2 : name = Using django forms for searching the database. With object 1 is bookmarked by 20 users and Object 2 is bookmarked by 10 users and i type in my search bar : Using django forms database In the result i have the first object as the first answer shown in the list even if the second one have much more matchs with the searched keywords. So what i want to do here is to sort the result … -
How to fix 'The included URLconf 'gp.urls' does not appear to have any patterns in it'
when i tried to write the first urlpattern and the first view, i got this error, so i can be able to access to the authentification template, i have no idea what can be the source of this error # my gp/utls.py from django.contrib import admin from django.conf.urls import url from . import views urlpatterns = [ path('admin/', admin.site.urls), url(r'^$', views.index, name='index'), ] # my views.py from django.shortcuts import render def index(request): return render(request,'gp/index.html') when i try to run the server this is the error i get raise ImproperlyConfigured(msg.format(name=self.urlconf_name)) django.core.exceptions.ImproperlyConfigured: The included URLconf 'gp.urls' does not appear to have any patterns in it. If you see valid patterns in the file then the issue is probably caused by a circular import. -
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. -

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? -

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.

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. There was few options, so I decided for processing like in this answer I used processing module, inserted it into view and vola, error from title.

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.

Preview the photo after selecting the file - Django
I can not find information on this topic. How to easily create a preview of the photo in Django after selecting it (before saving the form).

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 … -
Related name not working for django many to many field django
I am trying to access the value of an object that holds the ManyToMany relationship, similar to a related name for a ForeignKey or a OneToOne. How do I need to change my models to allow this? This is my current models.py from django.db import models from django.contrib.auth.models import User class Account(models.Model): account_owner = models.OneToOneField(User, on_delete=models.CASCADE, related_name='account_owner') account_name = models.CharField(max_length=50) members = models.ManyToManyField(User, related_name='account_profile') When I try {{ request.user.account_owner.account_name }} I get the expected value of the account name (if they are the owner). But when I try {{ request.user.account_profile.account_name }} I get nothing.
