How to handle FileNotFound error when using img tag using mark_safe in django admin
I am importing images into AWS S3 using django-storages. However, if Django admin does not have the corresponding image in S3, Admin would like to issue a FileNotFoundError to correct the S3BotoStorage object or fix the underlying problem to handle the error. admin/hospital.py class HospitalAdmin(OrderedInlineModelAdminMixin, IdFieldIncludedModelAdmin): list_display = ("name", "tags_comma_separated", "created_at") list_display_links = ("name",) list_filter = [TagFilter] fieldsets = ( (None, {"fields": ("user",)}), ( None, { "fields": ( "logo_image", "logo_image_width", "logo_image_height", "logo_image_preview", "name", "description", "address", "longitude", "latitude", "near_station_name", "phone_number", "sms_phone_number", ) }, ), ( None, { "fields": ( "created_at", "updated_at", ) }, ), ) readonly_fields = [ "logo_image_width", "logo_image_height", "logo_image_preview", "created_at", "updated_at", ] ... # FileNotFound Error occurs in the lower part @display(description="preview log image") def logo_image_preview(self, obj): return mark_safe( '<img src="{url}" width="{width}" height="{height}" />'.format( url=obj.logo_image.url, width=obj.logo_image.width, height=obj.logo_image.height, ) ) I added a try/except statement to the error part to generate a correct error, but it doesn't seem to solve the fundamental problem try: return mark_safe( '<img src="{url}" width="{width}" height="{height}" />'.format( url=obj.logo_image.url, width=obj.logo_image.width, height=obj.logo_image.height, ) ) except FileNotFoundError as e: return str(e) -

Django PasswordResetView does not work for inactive users
I have a simple django app where users can create and login to their accounts. When a user is registering for a new account, the user object is created and saved in the database with the is_active flag set to false. Once the user clicks the confirmation email, the user object has its is_active flag set to true. I have built out a password reset flow using Django's views: PasswordResetView, PasswordResetDoneView, PasswordResetConfirmView, and PasswordResetCompleteView. Everything works as expected unless I am trying to reset the password for an account which has not yet been activated (is_active == False), in which case, the reset password email is never sent to the user. The edge case I am considering here is for a user who created an account, and never clicked the registration link which expires after 72 hours, and thus have a user account which exists but is not active. Then the user wants to get a new registration link, and to do so I require a user to enter their username and password (so that no malicious actors can spam a random users email inbox with new registration link emails). If the user has since forgotten their password, they are … -
Displaying Countdown in Django Loop not working properly when clicked

How to show all the tags related to a publication in a list of publications filtered by a tag in Django?
Consider following models: # models.py from django.db import models class Tag(models.Model): name = models.CharField() number_of_publications = models.PositiveIntegerField() class Publication(models.Model): text = models.TextField() tags = models.ManyToManyField(Tag) # urls.py from .views import publications_tagged urlpatterns = [ path('/questions/tagged/<str:name>', publications_tagged) ] # views.py from .models import Tag, Publication from django.shortcuts import get_object_or_404, render def publications_tagged(request, name): tag = get_object_or_404(Tag.objects.prefetch_related('tags_set'), name=name) return render(request, 'myapp/tagged_questions.html', {'tag': tag}) Ok, so when we'd go to a template and make a for-loop that will create a representation of every publication and show appropriate tags of it, Django would make a database call for every publication to fetch all the tags the publication has, meaning: Iteration x of tag.tags_set -> check what tags match with publication X. Of course, we can just not show tags and everything will work like magic (utilizing prefetch_related), but that's not what we want :) How could we do something similar in Django? What we want is some kind of optimized way to achieve such a result, because stackoverflow renders 15 items really fast, which makes me think they do not do it the monkey way that Django does by default. This is what html might look like P.S. My problem doesn't quite sound like … -
How can I prevent row duplicates in Django when no field is unique?
Upon saving an object, is there a simple way to prevent duplication when the combination of all the fields together have the same data? The unique=True parameter doesn't seem to help here, because individually any of the data could be duplicated, but never all of them at the same time. If statement with several and conditions does not seem to me like a smart way so I'm looking for a better approach. Does Django provide it? All I could find was related to one field or other being duplicated. Ex.: if Model.objects.filter(field_A=source_A).exists() == True and Model.objects.filter(field_B=source_B).exists() == True and Model.objects.filter(field_C=source_C).exists() == True: continue else: *save object* -

My function to check for ajax on a page is not working
I am making a django project where there is a search/filter dropdown for a form. I am using select2 and ajax. It isn't working, and when I try to debug with print statements, it seems that the is_ajax(request) function is not returning true. I know the is_ajax() function was deprecated in JQuery, which is why I defined it myself. However, mine doesn't seem to work either. Here is the portion my view that filters objects: @login_required def job_application_create(request): form = JobApplicationForm() if is_ajax(request): print('TESTING TESTING TESTING TESTING TESTING TESTING TESTING TESTING ') term = request.GET.get('term') companies = Company.objects.filter(name__icontains=term) response_content = list(companies.values()) return JsonResponse(response_content, safe=False) and here is the is_ajax(request) definition: def is_ajax(request): return request.headers.get('x-requested-with') == 'XMLHttpRequest' I also tried this function: def is_ajax(request): return request.META.get('HTTP_X_REQUESTED_WITH') == 'XMLHttpRequest' Here is the JS in the page that has my form: <script> $(document).ready(function () { $('#id_company').select2({ ajax: { url: "{% url 'homepage' %}", dataType: 'json', processResults: function (data) { return { results: $.map(data, function (item) { return {id: item.id, text: item.name}; }) }; } }, minimumInputLength: 1 }); }); </script> -

Is there a way to enable secure websockets on Django?
I can't use secure websockets on Django with the sll enabled. I use the sslserver package for Django to allow HTTPS on the development server. My goal is to make a secure chat.
