Django list display of foreign key attribute that is boolean field using check or cross icons
My problem is similar to this thread: Can "list_display" in a Django ModelAdmin display attributes of ForeignKey fields?. I want to display a foreign key attribute from the list display. This attribute is a BooleanField. Normally, it would display a check or cross if the admin page is on the model itself containing the field. Such as this: However when I reference this to other admin page. class ProofOfPaymentAdmin(admin.ModelAdmin): list_display = ('id', 'reference_number', 'user', 'is_subscribed',) def is_subscribed(self, obj): return obj.user.is_subscribed The return from the list display is the boolean values True or False. How can I change this to display the icons check or cross similar from the above? -
How to return to main page (with POST data) after viewing detail pages in Django
I am building a Django (4.1) app that managers can use to view production data. An initial GET request /prod-query request displays a blank form with machine, part, and date fields. Submitting the form creates a POST request to /prod-query that displays a list of machines with production data filtered by the above data. Each row of the above data is a link to a detail page for that machine. The detail page for that machine has Next and Prev buttons that show the same detail page for previous or next time periods. I also have a Back button that I want to return to the last /prod-query with the POST data so it displays the last data set. Note: I can't use onclick="history.back() as the page I want may not be the last page viewed. Is there a simple way to do this I am missing? Do I need to put the POST data in the session and check for it when I make a GET to the original URL? The data size isn't an issue. Just thinking there should be a more Pythonic way. For now, I am going to create a form in the detail pages that … -
django-wkhtmltopdf not loading apex charts
I'm working on a project where I need to export some reports about a certain entity, using wkhtmltopdf with an html template that includes some charts from ApexCharts.js. The charts load fine in a rendered html but not in the pdf generated.

In my Django web page i have a for loop which creates multiple instances of a form. In each form i would like to execute some Javascript code when the page is loaded.

Passing variable from urls.py to html
I set django-built-in messages to pass some info from my views.py file to html file directly. I'm using directly messages.info(request, "User credentials are updated.") to send messages. As you see below, it works fine. Right now, I am planning to pass variables from urls.py to HTML directly. Something like below: path('password_change_done/', auth_views.PasswordChangeDoneView.as_view(template_name="account/dashboard.html"), **{'messages': 'User credentials are updated.'}**, name='password_change_done') When I search for it, I see that I can send a dictionary but it doesn't work for me. I tried to stick the same format(messages dictionary) where HTML expects. **{'messages': 'User credentials are updated.'}** Part of my urls.py file: # Password change # 1 ) Submit password change form path('password_change/', auth_views.PasswordChangeView.as_view(template_name="account/password/password-change-form.html"), name='password_change'), # 2 ) Success message stating that password is changed path('password_change_done/', auth_views.PasswordChangeDoneView.as_view(template_name="account/dashboard.html"), **{'message': 'User credentials are updated.'}**, name='password_change_done'), Part of my dashboard.html file: <!-- Django's built-in message template part --> {% for message in messages %} {% if message.level == DEFAULT_MESSAGE_LEVELS.SUCCESS %} <h6 id="message-timer" class="alert alert-success text-center"> <i class="fa fa-sign-out" aria-hidden="true"></i> &nbsp; {{ message }} </h6> {% endif %} {% if message.level == DEFAULT_MESSAGE_LEVELS.ERROR %} <h6 id="message-timer" class="alert alert-danger text-center"> <i class="fa fa-exclamation" aria-hidden="true"></i> &nbsp; {{ message }} </h6> {% endif %} {% if message.level == DEFAULT_MESSAGE_LEVELS.INFO %} <h6 … -
Django rest freamework: get a path parameter in the serializer
I request to a service with this path: /api/story_step/<chatbot>/<story_name>/ And in the suitable Django serializer I have the following field: interaction_name = serializers.CharField(source='interaction.name', read_only=True) Which is a reference to another table field: interaction = models.ForeignKey('interactions.Interaction', models.CASCADE, 'story_interaction', 'story_interaction') Is there any way to filter that field by the path parameter in order to see only the interactions of that defined chatbot?

How to hash previously saved password in phpmyadmin in Django

Django: how to clear session variables on page load, that way that paginator won't clear them

Form marked for deletion but empty FormSet.deleted_forms
I've got a piece of code similar to the following: from django.forms import inlineformset_factory class EmailForm(forms.ModelForm): class Meta: model = MyModel EmailFormSet = inlineformset_factory( MyRelatedModel, MyModel, form=EmailForm, can_delete=True, extra=0 ) And I've got a custom class-based view which works perfectly fine for creating/saving new MyModel instances and for editing existing instances. When I mark a form / an instance for deletion, I can see my view receives the following POST method: <QueryDict: { 'csrfmiddlewaretoken': ['XXX'], 'email-TOTAL_FORMS': ['1'], 'email-INITIAL_FORMS': ['1'], 'email-MIN_NUM_FORMS': ['0'], 'email-MAX_NUM_FORMS': ['1000'], 'email-0-id': ['94ef2d4c-b2fc-4082-a460-e4344ddb20d4'], 'email-0-value': ['12345'], 'email-0-DELETE': ['on'], }> I believe this is, again, the expected behavior, in particular the formset.data do contain {'email-0-DELETE': ['on']} and the form is valid. However, the corresponding instance is not deleted. Indeed, when I display formset.deleted_forms, it turns out to be an empty list. Why? I've tried to deep dive into Django's inner mechanisms and I've noticed the method deleted_forms relies on another called _should_delete_form which simply returns form.cleaned_data.get(DELETION_FIELD_NAME, False). But in my case, form.cleaned_data only contains {'value': '12345'}, no "DELETE" key... So how is _should_delete_form supposed to return something else than False? Am I supposed to explicitly add a DELETE field to EmailForm, isn't the formset supposed to manage that extra field? -

Optimizing Django db queries for Viewset
I recently was tasked to optimize db queries and performance of some of our django rest apis written in drf and was able to successfully use prefetch_related() to implement them. But there is one usecase I have been unable to resolve and looking for support on the same. Here goes the structure: Models.py class Section(models.Model): section_tags = models.ManyToManyField(AssetTag) section_name = models.CharField(max_length=200) section_createdate = models.DateTimeField(auto_now=True) class Collection(models.Model): section = models.ForeignKey(Section, on_delete=models.CASCADE, related_name="collection_set") system_tags = models.ManyToManyField(AssetTag, blank=False, related_name='system_tags_poster_collections') card = models.ManyToManyField(Card) class Card(models.Model): tag = models.ManyToManyField(CardTag) # should we deprecate? system_tags = models.ManyToManyField(AssetTag, blank=False, related_name='system_tags_poster_cards') card_name = models.CharField(max_length=200) views.py class SectionViewset(viewsets.ModelViewSet): serializer_class = serializers.SectionSerializer http_method_names = ['get'] def get_queryset(self): queryset = Section.objects.filter(section_status=True, section_expiredate__gte=datetime.now()) return queryset serializer.py class SectionSerializer(serializers.ModelSerializer): collection_set = CollectionSerializer(many=True, read_only=True) class FilteredCollectionSerializer(serializers.ListSerializer): def to_representation(self, data): data = data.filter(collection_status=True, collection_expiredate__gte=datetime.now()) return super(FilteredCollectionSerializer, self).to_representation(data) class CollectionSerializer(serializers.ModelSerializer): card = CardSerializer(many=True, read_only=True) system_tags = AssetTagBadgeSerializer(many=True, read_only=True) class Meta: list_serializer_class = FilteredCollectionSerializer model = Collection fields = ('id', 'card', 'system_tags') I am unable to apply prefetch_related() to get any optimization of the queries on the SectionViewSet since it is sort of a reverse relationship in the Collection Model.

Efficient debugging Django with pdb – like Sentry
I use pdb to debug in Django. Sometimes it works, sometimes it does not catch the issue, just runs over the error. I have another example, the way how Sentry shows the bugs. Exactly at the place where it is relevant. Could I use pdb similarly? Maybe via the "where" command? It would be so useful! An example: if there is a bug in one of the serializers, it is so hard to find the relevant code place. Django server just gives a "non_field_errors":["Something unexpected has occured. Please contact an admin to fix this issue."]. On the other hand, Sentry can show the hot spot. So it "can" be found. I would like to find it with pdb also! -

Django Template tag 'with' not working as expected

Django - When using Easy Thumbnails how to force a field to convert the thumbails to JPG even if PNG with alpha was provided
When using Easy Thumbnails you can globally configure that all images (even PNGs with alpha) are converted to JPG by adding this to your settings.py THUMBNAIL_TRANSPARENCY_EXTENSION = 'jpg' But the problem is that I don't want to force ALL of my images in my application to be converted to JPG because I have some models that require images with alpha (png). I have a model for a blog article where I need the image to ALWAYS be converted to JPG. No matter if people upload PNGs with alpha. class Article(BaseModel): title = models.CharField(max_length=255, unique=True) image = ThumbnailerImageField(upload_to='blog/articles/image') Right now many people are uploading PNG's with alpha enabled (although the image doesn't have any transparency) and this is preventing the Thumbnailer to compress them as JPG making many of the thumbnails 500kb(png) instead of like 70kb(jpg). How can I specify to always convert these article images to JPG?
