Reset many to many fields from model
I want to reset all upvotes from all my Posts with django-orm, don`t know how to write query for that and apply it to the view. Also, maybe it would be better to make separate upvote model than just a field in the Post. class Post(models.Model): author = models.ForeignKey( User, related_name='posts', on_delete=models.SET_NULL, null=True ) title = models.CharField(max_length=100) creation_date = models.DateTimeField(auto_now_add=True) link = models.URLField() upvotes = models.ManyToManyField(User, related_name='upvotes', blank=True) -

How can I install psycops2 in my virtual env?
I need to install psycopg2 for connecting postgresql with django.I have tried this command. pip install psycopg2 but this message was shown: Error: pg_config executable not found. pg_config is required to build psycopg2 from source. Please add the directory containing pg_config to the $PATH or specify the full executable path with the option: python setup.py build_ext --pg-config /path/to/pg_config build ... or with the pg_config option in 'setup.cfg'. If you prefer to avoid building psycopg2 from source, please install the PyPI 'psycopg2-binary' package instead. For further information please check the 'doc/src/install.rst' file (also at <https://www.psycopg.org/docs/install.html>). ---------------------------------------- Command "python setup.py egg_info" failed with error code 1 in C:\Users\Rafid\AppData\Local\Temp\pip-install-oknhhl43\psycopg2\ I am new to web development so a detailed solution will be helpful...Thanks in advance -

Blacklist the token once there is a changes in role or permission in django rest framework simple-jwt
I would like to blacklist the token (and redirect to login page) once there is a changes in role or permission of a specific user. The admin only can change the role. If any point of time, the role and permission changed it should automatically blacklist the token. I mean there will be a function of blacklist token, if any changes detected that function should execute automatically. Note : user does't have any idea about his role change or not. There will be mechanism that will detect automatically the changes and execute the blacklist method to blacklist the token and redirect to login page. Any inputs would be really appreciated. -
Suggestions on implementing search with Django and Python
I've been venturing recently into python and django, and was looking to build a website that displays information retrieved from a dataset, very similar to this website - https://art-explorer.azurewebsites.net/. This is just a project to develop my skills, and will not necessarily be deployed live. The database currently has a thousands of rows that display information about objects, including tags, metadata, and URLs of images. My goal was to implement a search engine that goes through all of the images linked in the dataset and displays them with some kind of metadata information, such as author, year, title, etc. The user should have the option to filter through these images by selecting tags, specific years, authors or just search by keywords. I already have the basic structure of the website implemented in Django, including the HTML and CSS, and was thinking on using SQLite for the database. I'm pretty new to this, so this may not be the best implementation or even feasible. Do you think this is doable with the current structure I'm going for, is there a better way to implement this in a way that it will be more efficient in the backend? Thanks! -

GEOS_ERROR: ParseException: Unknown WKB type 337

how to generate unique id in factory using faker: Django
I am trying to insert data into my database (sqlLite3) using factory and faker. This is my model: class User(models.Model): id = models.CharField(max_length=9, primary_key=True) real_name = models.CharField(max_length=200) tz = models.CharField(max_length=200) Factory for the model: class UserFactory(factory.django.DjangoModelFactory): class Meta: model = User fake.add_provider(MyProvider) real_name = factory.Faker('name') id = ''.join(fake.random_letters(length=9)).upper() tz = fake.timezone() When I run UserFactory.create() for the first time, User is added but when I run the second time in the same python shell or try to run UserFactory.create_batch(5), it gives me the following error: django.db.utils.IntegrityError: UNIQUE constraint failed: activities_user.id If I run it in a different terminal or exit from shell and run the same command again it runs fine. Seems ''.join(fake.random_letters(length=9)).upper() always returns same value. Even though I have used random_letters I wonder why this is happening. I am new to using factory boy and faker. Please help me out on this. Let me know if I am missing anything. -

Password Reset Email Not Being Sent in Django
First of all, I'd just like to clarify that I've looked at all the other questions in regard to this on Stack Overflow and I haven't been able to resolve the issue. So, the issue I'm having is that I'm not receiving a password reset email on my site, even though everything indicates that the email has been sent. I say this because I get the confirmation on my screen that the email has been sent and I also get the email displayed in the console (see below). Here are my email settings: EMAIL_BACKEND = "django.core.mail.backends.console.EmailBackend" EMAIL_USE_TLS = True EMAIL_HOST = "localhost" EMAIL_PORT = 25 EMAIL_HOST_USER = os.environ.get("EMAIL_ADDRESS") EMAIL_HOST_PASSWORD = os.environ.get("EMAIL_PASSWORD") Here are my password reset URLs: from django.conf.urls import url from django.core.urlresolvers import reverse_lazy from accounts.views import change_password from django.contrib.auth.views import ( password_reset, password_reset_done, password_reset_confirm, password_reset_complete) urlpatterns = [ url(r'^$', password_reset, name='password_reset'), url(r'^reset-password/done/$', password_reset_done, name='password_reset_done'), url(r'^reset-password/confirm/(?P<uidb64>[0-9A-Za-z]+)-(?P<token>.+)/$', password_reset_confirm, name='password_reset_confirm'), url(r'^complete/$', password_reset_complete, name='password_reset_complete'), url(r'^change-password/$', change_password, name='change_password'), ] Any feedback is greatly appreciated! Thanks in advance. -

Django dictionary sort by value
Now, I am making a web that tells how many words are in the input I want to post top 15 most-used words as well def count(request): entered_text = request.GET['textarea'] word_list = entered_text.split() word_dictionary = {} for word in word_list: if word in word_dictionary: word_dictionary[word] += 1 else: word_dictionary[word] = 1 return render(request,'count.html', {'alltext':entered_text, 'total':len(word_list), 'dictionary':word_dictionary.items()}) These are codes that I made right now. I want to sort word_dictionary by value. I tried to use sorted function which I used in python but it doesn't work Is there any ways to sort word_dictionary? -
Confusion in id parameter in django
I was making an E Commerce website and added various products in it. Now for making a cart i made a add to cart button. And in HTML i assigned an id to this button. The id was pr{{product.id}}. I have not made buttons individually for every item. There is a for loop running which creates buttons. Now My doubt is that i have not assigned any field id in the models class. But still this code is running and when i printed the id's on the console i realised that it prints like pr32, pr33, pr34 ie in a sequential manner. So is there any product.id field predefined in django?? -
