How to make Django show hint's in case password doesn't meet requirements during registration?
Can anyone please tell me how to make Django actually display hints\messages\errors or whatever in case during registration process user's password doesn't meet standart requirements? Because now it is just absolutely silent about that. Here's my form class Registration(UserCreationForm): class Meta: model = User fields = ['username', ] and here's my view def register(request): if request.method == 'POST': form = Registration(request.POST) if form.is_valid(): user = form.save() login(request, user) return redirect('upload') else: form = Registration() return render(request, 'testapp/temp1.html', {'form': form}) Thank you in advance! -
Reverse comments list in descending order to get the last n (2) objects in django template
I've searched a lot and couldn't find anything to reverse the comment's list in descending order so that I can get the last two comments of each post in the template. Here is my model: class Comment(models.Model): post = models.ForeignKey(Post, on_delete=models.CASCADE, related_name='comments') commented_by = models.ForeignKey(User, on_delete=models.CASCADE) comment = models.CharField(max_length=128) views.py: posts = Post.objects.all().order_by("date_posted").reverse() return render(request, "cs50gram/explore.html", {"posts": posts}) template.html: {% for post in posts %} {% for comment in post.comments.all|slice:":2" reversed %} <div style="color: gray"> <b> {{ comment.commented_by }} </b> {{ comment.comment }} </div> {% endfor %} {% endfor %} The problem here is that it slices first and then reverse.. What have I tried? How to reverse a for loop in a Django template and then slice the result Using the solution presented in the answer, it didn't work for some reason. This is exactly how I tried it in my code. {% for post in posts %} {% for comment in post.comments.all.reverse|slice:":2"%} <div style="color: gray"> <b> {{ comment.commented_by }} </b> {{ comment.comment }} </div> {% endfor %} {% endfor %} The output is that it only slice it without reversing.

OuterRef not looking into outer query
I have the following model schema (only putting here the important variables): class Department(models.Model): name = models.CharField(max_length = 64) class User(AbstractUser): departments = models.ManyToManyField(Department, related_name = 'users', blank = True) date_left = models.DateTimeField(null = True, blank = True) ## date_joined = This is set by default on AbstractUser class Office(models.Model): department = models.ForeignKey(Department, related_name = 'offices', on_delete = models.CASCADE) class Invoice(models.Model): office = models.ForeignKey(Office, related_name = 'invoices', on_delete = models.CASCADE) date = models.DateField(null = True, blank = True) ## nr_workers = The annotation i'm trying to create below And i want to retrieve, for every Invoice date, the number of active users. For example, invoice.date = '2021-04-01' -> nr_workers should be equal to the number of users from that invoice.office.department who joined before 2021-04-01 and, either left after that date, or never left at all.

How to get another related result in a django model
Let's say I have this model in django: class DeviceSensorChange(models.Model): device = models.ForeignKey(Device, on_delete=models.CASCADE, db_index=True) sensor = models.ForeignKey(DeviceDigitalSensor, on_delete=models.CASCADE, db_index=True, related_name='sensorchanges') time = models.DateTimeField(auto_now_add=True) value = models.BooleanField(default=False) it describes how and when some "sensors" changes in time (a history of binary buttons: on and off). Then there is a ListView filtered by device or by sensor or by time. I want to add another column in the view, that shows the elapsed time since the last change of the same sensor in the same device: it means I should to go back in the table looking for the same device, same sensor, get the time and make the subtraction. Where is the right place to do that? I must not change the model and the information is needed just in the view to help the user, no need to store it. Is it possbile to add a elapsed() function in the model? Or this is something that has to be done in the template? Or in the ListView itself? -
Failing to load static CSS from Django on Azure
I followed this tutorial from DigitalOcean and have this in my settings.py. STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, 'static') However, after deploying my app, I find that the CSS file's request is canceled as seen in Chrome tools. I still get this error even after running: $ python manage.py collectstatic which gives me files in staticfiles directory for admin and app. Note that I can run all this on localhost with no issue. I tried the suggestion in this answer by switching from /static/ to static/ but ran into the same issue. Given that I want to retain this structure of static files in their respective app directories and don't have CSS files that are not tied to any app, I can't use STATICFILES_DIRS as the documentation says. Your project will probably also have static assets that aren’t tied to a particular app. In addition to using a static/ directory inside your apps, you can define a list of directories (STATICFILES_DIRS) in your settings file where Django will also look for static files. -

How to change the URL structure of already Google Indexed Django Website?
I have a Website built in Django. The blogs posts of my website have the url https://saralgyaan.com/posts/. But due to extensive posting on Facebook, it banned the url https://saralgyaan.com/posts/ (I still can post https://saralgyaan.com on Facebook). So, I was wondering, if I could remove the posts from my URL, I would be able to share my posts on Facebook. I need to change the URL structure to this effect. But my website is already indexed on Google and I get organic search landing on almost 10 pages, so I don't want to disrupt that. I was wondering If somehow I could use the RedirectView to redirect https://saralgyaan.com/ to https://saralgyaan.com/posts/. Is it possible? Will Facebook allow me to post or it will detect the redirect URL and again stop me from posting it. My urls.py of application is from django.urls import path, re_path from .views import( posts_search, posts_create, posts_detail, posts_edit, posts_delete, show_category, tag_posts, posts_publish, category_create ) urlpatterns = [ path('', posts_search, name='search'), path('create/', posts_create, name='create'), path('category/', category_create, name='category_create'), re_path(r'^category/(?P<hierarchy>.+)/$', show_category, name='category'), # path('category/<slug>/', show_category, name='category'), path('<slug>/', posts_detail, name='detail'), path('<slug>/edit/', posts_edit, name='edit'), path('<slug>/publish/', posts_publish, name='publish'), path('<slug>/delete/', posts_delete, name='delete'), path('tags/<tag>/', tag_posts, name='tag_posts') ] And the urls.py of the project is urlpatterns = [ … -

How to access heroku config vars using javascript in order to pass to Square Payment?
I am trying to add Square's Web Payment SDK to my site. I am using latest python, Django and hosting on Heroku. I need to access the APPLICATION_ID and LOCATION_ID which will be stored in Heroku Config Vars. These are required in order to display the card payment form on my site. I know javascript cannot access them and the only solution I have seen requires setting up a templatetag and having the input="hidden" in the HTML. How to access environment variable from html or js in Django Square provides the following code to include in my HTML however, I cannot simply replace APPLICATION_ID with its value in the text as it must be kept secret and I dont want it in the DOM. <body> <form id="payment-form"> <div id="card-container"></div> <button id="card-button" type="button">Pay</button> </form> <!-- Configure the Web Payments SDK and Card payment method --> <script type="text/javascript"> async function main() { const payments = Square.payments(APPLICATION_ID, LOCATION_ID); const card = await payments.card(); await card.attach('#card-container'); async function eventHandler(event) { event.preventDefault(); try { const result = await card.tokenize(); if (result.status === 'OK') { console.log(`Payment token is ${result.token}`); } } catch (e) { console.error(e); } }; const cardButton = document.getElementById('card-button'); cardButton.addEventListener('click', eventHandler); } main(); </script> … -

Elasticsearch scoring on multiple indexes: dfs_query_then_fetch returns the same scores as query_then_fetch
I have multiple indices in Elasticsearch (and the corresponding documents in Django created using django-elasticsearch-dsl). All of the indices have these settings: settings = {'number_of_shards': 1, 'number_of_replicas': 0} Now, I am trying to perform a search across all the 10 indices. In order to retrieve consistent scoring between the results from different indices, I am using dfs_query_then_fetch: search = Search(index=['mov*']) search = search.params(search_type='dfs_query_then_fetch') objects = search.query("multi_match", query='Tom & Jerry', fields=['title', 'actors']) I get bad results due to inconsistent scoring. A book called 'A story of Jerry and his friend Tom' from one index can be ranked higher that the cartoon 'Tom & Jerry' from another index. The reason is that dfs_query_then_fetch is not working. When I remove it or substitute with the simple query_then_fetch, I get absolutely the same results with the identical scoring. I have tested it on URI requests as well, and I always get the same scores for both search types. What can be the reason for it? -

Django issue with post_delete signal when deleting a object having child objects of the same model
When the post_delete signal is used to send a notification alert to user about comment deletion the following error occurs only when there is replies associated with it. If the comment has no replies it works fine. Comment models.py partial code user = models.ForeignKey(get_user_model(), on_delete=models.CASCADE, default=None) parent = models.ForeignKey('self', on_delete=models.CASCADE, null=True, blank=True) content = models.TextField() So, the comment without a parent is main comment and with a parent is reply. signals.py partial code def CommentDelete_handler(sender, instance, **kwargs): print(instance) post_delete.connect(CommentDelete_handler, sender=Comment) Here just accessing the instance will generate an error Comment matching query does not exist. I am not clear with the working mechanism inside this process, and why it works with a single comment but when it has replies inside it generates errors. Note: I fixed this case using the pre_delete signal instead of the post one which works fine in both cases. If anyone suggests the working mechanism and why post_signal fails on this or is there any update I can do to make it work in post_signal. Thank you for the support. -
