Django Test Client returning error on client.get(reverse('polls:index'))
working through the Django tutorial and running into issues. Patience appreciated! I'm on part 5 attempting to use the test client. When I run: > response = client.get(reverse('polls:index')) I get the following error: TemplateSyntaxError: Invalid block tag on line 38: '<span', expected 'empty' or 'endfor'. Did you forget to register or load this tag? I'm sure it has to do with my index.html or some other file associated with my Django code so please ask me to edit this post with applicable files. For now, here is the index.html code: <meta charset="utf-8"> <title>My test page</title> </head> <body> <h1>subtitle test thing</h1> <p> {% if latest_question_list %} <ul> {% for question in latest_question_list %} <li> <a href=“{% url 'polls:detail' question.id %}”>{{ question.question_text }} </a> </li> {% endfor %} </ul> {% else %} <p>No polls are available.</p> {% endif %} </p> </body> </html> Fair point here: I DO NOT KNOW HTML. I understand that Django provides incomplete HTML so I did my best to build structure around it. I have no idea if it's even right. Other files that might be helpful: urls.py: > from django.urls import path from . import views > > app_name = 'polls' urlpatterns = [ > path('', views.IndexView.as_view(), … -

Error accessing Sendinblue (Hosting: Pythonanywhere)
¡Hello! I have recently deployed a website developed in Django to Pythonanywhere. The web is integrated with Sendinblue, I checked the Whitelisted and saw that the API is allowed for free accounts in Pythonanywhere. I ask for your help because all the API queries give me errors like the one I show you at the end, on the other hand everything works fine outside the hosting.

Stop forloop tag template - Django
I am trying to stop a "forloop" tag template in Django, but I couldn't find a way to do that. In my Django template, I want to show all the articles that I have in my database. And each of those articles is connected to one or more SDGs. For now, my code is showing all the related SDGs, but I would like to only show the first result, and thus stop the "forloop" as soon as there is one positive result. Would someone know how to do that? Here is my Django template: <section> <div class="row px-4"> {% for article in articles %} <div class="col-md-12 col-lg-3 px-3 mb-5" data-aos=fade-up> <div class="card shadow lift rounded"> <div class="card-body py-4"> <h3 class="card-title">{{ article.title }}</h3> {% for sdg in sdg_seed_image %} {% if sdg.seed_id == article.id %} <h4>{{ sdg.sdg_id }}</h4> {% endif %} {% endfor %} </div> </div> </div> {% endfor %} </div> </section> Here is my view code: def article_view(request): articles = Article.objects.all().order_by("-date_publication") sdg_seed_image = SDG_Seed.objects.all() return render(request, "dist/inside/article/view_all.html", context={"articles": articles, "sdg_seed_image": sdg_seed_image}) -

dj-rest-auth limit social sign up to a specific email address domain
I'm getting started with dj-rest-auth and I have an app which allows user to only sign in via google. However, I want users to only be able to access my service with a specific google apps email domain. I'm using dj-rest-auth in conjunction with django-allauth. This is what I tried: I created allauth adapters like this: class CustomAccountAdapter(DefaultAccountAdapter): def is_open_for_signup(self, request): return False # No email/password signups allowed class CustomSocialAccountAdapter(DefaultSocialAccountAdapter): def is_open_for_signup(self, request, socialaccount): u = socialaccount.user return u.email.split("@")[1] == "mydomain.com" and in my settings I have ACCOUNT_ADAPTER = "users.adapters.CustomAccountAdapter" SOCIALACCOUNT_ADAPTER = "users.adapters.CustomSocialAccountAdapter" With this solution, if the user tries to sign in with a valid email, everything works, whereas if they use a non-allowed email domain, I get this error in my console: Traceback (most recent call last): File "/home/my_user/.local/share/virtualenvs/my_project-mzTAT1MS/lib/python3.8/site-packages/django/core/handlers/exception.py", line 47, in inner response = get_response(request) File "/home/my_user/.local/share/virtualenvs/my_project-mzTAT1MS/lib/python3.8/site-packages/django/core/handlers/base.py", line 181, in _get_response response = wrapped_callback(request, *callback_args, **callback_kwargs) File "/home/my_user/.local/share/virtualenvs/my_project-mzTAT1MS/lib/python3.8/site-packages/django/views/decorators/csrf.py", line 54, in wrapped_view return view_func(*args, **kwargs) File "/home/my_user/.local/share/virtualenvs/my_project-mzTAT1MS/lib/python3.8/site-packages/django/views/generic/base.py", line 70, in view return self.dispatch(request, *args, **kwargs) File "/home/my_user/.local/share/virtualenvs/my_project-mzTAT1MS/lib/python3.8/site-packages/django/utils/decorators.py", line 43, in _wrapper return bound_method(*args, **kwargs) File "/home/my_user/.local/share/virtualenvs/my_project-mzTAT1MS/lib/python3.8/site-packages/django/views/decorators/debug.py", line 89, in sensitive_post_parameters_wrapper return view(request, *args, **kwargs) File "/home/my_user/.local/share/virtualenvs/my_project-mzTAT1MS/lib/python3.8/site-packages/dj_rest_auth/views.py", line 48, in dispatch return super(LoginView, self).dispatch(*args, **kwargs) File "/home/my_user/.local/share/virtualenvs/my_project-mzTAT1MS/lib/python3.8/site-packages/rest_framework/views.py", line … -

Is Django's Caching Framework per user or across all user's
I have read through Django's caching framework documentation (https://docs.djangoproject.com/en/3.1/topics/cache/#), and want to know if the caching is per user or for all user's. For example, User A: Generates this link with parameters --> https://example.com/?parameters=hello User A: Re-opens the previous link and experiences a fast reload. User B: Opens the link User A generated, but does not experience a fast reload time. No where in the documentation does it state it's per user, but from testing it seems to be that way. I just want to know if this is the intended purpose behind the caching framework? If, so is there a way to cache the requests for all user's? -
How to redirect to different site, and pass auth credentials using Django
Is it possible to redirect to a different URL with authentication using django? For example, with python requests, I can log into a site by passing credentials like: UN= "myuser" PWD = "mypassword" loginUrl = "https://example.com/" client = requests.session() header_data = {'referer' : loginUrl, 'User-Agent' : 'Custom'} r = client.post(loginURL, auth=(UN, PWD), headers = header_data) But If I want a button on a django powered page to redirect to another site, and login into it automatically, how can this be done? I tried using redirect, which works to redirect obviously, but I can't seem to figure out how to pass auth crendtials using a django view. I also tried redirect(user:password@example.com) which gives an error that this feature is depreciated on chrome, and I cannot pass credentials this way. Any help is appreciated! -
Is Pinax still being maintained?
This question is basically an update for this one. I recently discovered the django pinax ecosystem but I am not sure if this is currently being maintained and works for recent versions of Django. Documentation is not clear to me on this. Since this is a collection of different apps it may happen that some of them are more maintained than others, so the question would be if most of the apps listed here and the pinax-starter-projects are up to date with current django/python versions in 2021 (django 2.2/3, python 3+) -

Django - Pandas - add_format: cell get format but only applied if enter keys is pressed

Only if I select a cell and press enter the format is recognised and applied: I can make the format to automatically apply to all cell? Thank you for your help -

Issues when converting image binary data from PostgreSQL using Python to string format

Django MYSQL created_date and mod_date with specific SQL
I'm relatively new to Django, and am trying to have the following SQL statements for two fields that appear in all of my models: sys_created_date timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP, sys_mod_date datetime DEFAULT NULL ON UPDATE CURRENT_TIMESTAMP, currently the model fields look like this: sys_created_date = models.DateTimeField(auto_now_add=True,blank=False,null=False) sys_mod_date = models.DateTimeField(auto_now=True) However, when I inspect the MYSQL database directly the fields look like this: `sys_created_date` datetime(6) NOT NULL, `sys_mod_date` datetime(6) NOT NULL, What would be the best (most Django appropriate) way to alter these MYSQL columns so that the constraints listed above are contained directly within the MYSQL database?

Is it possible to pass a variable variable when including Django template
