Change Django to use EmailMultiAlternatives instead of send_mail() by default (all-auth)
So I am using django-all-auth for my authentication and using its in-built functionality for mailing reset passwords, confirmations of registration, etc. I have designed templates that include images. For the regular emails, I am explicitly using functions that use EmailMultiAlternatives instead of send_mail() since that allows inline images and background images. Django-all-auth however automatically uses send_mail() and my emails are arriving with the images missing. How can I override it so it uses EmailMultiAlternatives? -
Collapsed field in Django Admin's change view
The table Content has a field compressed_string that stores a very long string in the compressed form. This is what I have to display the original decompressed string in the Django Admin's change view: class ContentAdmin(admin.ModelAdmin): fields = ( [f.name for f in Content._meta.fields if f.name not in ['compressed_string']] + ['original_string']) readonly_fields = ['original_string'] list_display = [f.name for f in Content._meta.fields] def original_string(self, obj): return pickle.loads(brotli.decompress(obj.compressed_string)) I would like original_string to be displayed collapsed, with the possibility to expand and view the whole string. How can I accomplish this? -
I am getting "NoReverseMatch" error for my 'results' page
I am creating a quiz website. After the user answers all the questions he is redirected to the results page. But if he clicks the back button in Chrome he goes back to the questions in the quiz. But since the quiz is submitted i don't want him to go there. Instead It should redirect him into the home page where a list of all quizzes is available. So in the templates of the results page I included the following JavaScript code. <script> window.onload = function() { // Check if the referring URL matches the results page URL console.log('Referrer:', document.referrer); var expectedReferringURL = '{% url "quizquestions" %}'; // Check if the referring URL contains the expected URL pattern name if (document.referrer.includes(expectedReferringURL)) { // Replace the current history entry with the home page URL window.history.replaceState(null, null, '{% url "quizlist" %}'); } }; </script> The url pattern of the name "quizquestions" is path('quizzes/<int:quiz_id>/question/<int:question_id>',user_views.quizquestions,name='quizquestions') But when I go to the results page it shows this error Reverse for 'quizquestions' with no arguments not found. 1 pattern(s) tried: ['quizzes/(?P<quiz_id>[0-9]+)/question/(?P<question_id>[0-9]+)\\Z'] Any thoughts on why is this happening? -
Update Django via settings to new domain
I'm new to Django and nginx. I have built a default Django app and my setup uses a nginx server as a reverse proxy. My application was previously reached via https://myapplication.intranet and every internal link referred to this link (e.g. href "/" points to "https://myapplication.intranet/" and href points to "/test" "https://myapplication.intranet/test") - so everything worked. Now nginx changed the domain link to "https://myapplication.intranet/new/", and everything broke: redirect (e.g. in view.py) href (in html templates. For example href "/test" incorrectly points to "https://myapplication.intranet/test" instead of "https://myapplication.intranet/new/test") css sheets not found My question is the following: What adjustments have to be made (for Django) in order to make the application work again? Is there an easier (and more general) way than rewriting all links in all files to make the urls specific? Thank you very much. -
Invoke Django reload manually
I would like to force a reload of Django similar to when Django reloads after a file has changed. e.g. Watching for file changes with StatReloader This answer has the desired result but it involves a reload on "file changing": https://stackoverflow.com/a/43593959/12446456 However, I would specifically like to invoke the reload behaviour manually after a get request has been handled by Django. -
Basic Django image runs locally but fail inside Kubernetes?
I created a bare minimal Django project using django-admin startproject I then dockerized it using the following Dockerfile FROM python:3 ENV PYTHONUNBUFFRED=1 COPY . . RUN pip install -r requirements.txt EXPOSE 8000 CMD ["python", "manage.py", "runserver", "0.0.0.0:8000"] I built and pushed the image to ACR. I am able to run it locally using docker run -p 8000:8000 <image_name> and I am able access the site at localhost:8000. However, when I try to deploy it inside a Kubernetes deployment with the following yml file, it just crashed and restart over and over. apiVersion: apps/v1 kind: Deployment metadata: name: demodjango-deployment labels: app: demodjango spec: replicas: 1 selector: matchLabels: app: demodjango template: metadata: labels: app: demodjango spec: containers: - name: demodjango image: djangonba.azurecr.io/demodjango:latest imagePullPolicy: "Always" ports: - containerPort: 8000 --- apiVersion: v1 kind: Service metadata: name: demodjango-service spec: type: LoadBalancer selector: app: demodjango ports: - protocol: TCP port: 8000 targetPort: 8000 I am unable to access the page through the external IP address of the service demodjango-service either even at time where it somehow didn't crash.

Django ModelForm: how do I pre-populate data for a ModelForm overriding a field's widget? (Some working, some not.)
I have a model form with a number of fields that need to use widgets other than the default widget for the model data type. Loading the update form before adding custom widgets, all the data pre-populates for the current object correctly. As soon as I add a custom widget for any field, the pre-population for that field breaks. For example, this works as expected: class ChecklistForm(forms.ModelForm): class Meta: model = Checklist fields = [ "expected_time", #TimeField "completed", #BooleanField, nullable ] But I want control over the widgets used. I'd like the boolean completed field to render as a checkbox even though it is nullable, so I add: class ChecklistForm(forms.ModelForm): class Meta: model = Checklist fields = [ "expected_time", #TimeField "completed", #BooleanField, nullable "date", #DateField ] widgets = { 'expected_time': forms.TimeInput(format='%H:%M',attrs={'type': 'time'}), 'completed': forms.CheckboxInput(), 'date': forms.DateInput(format=('%m/%d/%Y'), attrs={'placeholder':'Select a date', 'type':'date'}), } When I load an update form, completed pre-populates correctly, while expected_time and date do not. Why? And is there a way to pre-populate these fields automatically? -
Memory never releases on Heroku, slow memory leak from models in Django?
I have been troubleshooting memory leak issues on my Django application deployed to Heroku. Basically, when the app is deployed/dyno restarted RAM hovers around 40% then as soon as someone gets on, it goes to 80% usage then stays there and never goes back down. Here is a screenshot of my last 24 hours: Things I have tried: Caching expensive things that are called often (using @cached_property), like checking a users subscription that is tied to their organization. Optimizing my queries, so far the biggest queryset I bring back is ~20 rows and isn't particularly big. Ran a memory profiler (pympler) that has a tab on Django Debug Toolbar. Admittedly am unsure of what I am looking at. Lowered gunicorn workers to 2 instead of 4 Checked that database connections weren't going haywire (currently 2 connections) Some other ideas of what it could be but unsure how to properly troubleshoot: I have middleware where I check for a subscription that runs on most pages, could this be somehow leaking/storing data? If I hit a 3rd party API (which isn't that often in this app) do I have to actively run del to get it out of memory? Has anyone else … -
How to remove `b'\x80\x05\x95\x08\...` from the contents of cache in Django?

Django admin: displaying computed property when viewing a single item
I store compressed strings in the database. I would like to see the actual string when in Django Admin. Since the strings are very long, I don't want them to appear in the list view, but only when viewing a single item (row). So, I can define: @property def short_my_field(self): return pickle.loads(brotly.decompress(self.my_field))[:80] @property def original_my_field(self): return pickle.loads(brotly.decompress(self.my_field)) I will then put short_my_field into list_display. But how do I cause original_my_field to display when viewing a single item? -

How to display the chapters of the Bible from django-bible package?
I'm trying to display the chapters of the bible from the bible package available here https://github.com/davisd/django-bible. Some of the codes are deprecated and I have refactored some.

Django ORM Foreign Key Values how to return as single dictionary
How do I return all foreign key values into a single dict in the Django ORM? I understand how to access these values in Python, but I'm looking to retrieve them from a dict, rather than a class. class ChildModel(models.Model): location = models.TextField() class MasterModel(models.Model): town = models.ForeignKey(ChildModel, on_delete=models.CASCADE) To access the location in Python: queryset[0].town.location Accessing the values themselves does not return the location field. queryset.values() = {town: 1} What I want is: queryset.values() = {town: 1, location: some_value} If I run the SQL query in Postgres I get the dict I'm looking for (all inner join fields returned as a single dict). But how to do this in Django? -
Is there is option to cast django subquery object values to one text field
I have ticketing system, and for table view I'm using DataTables, I'm passing queryset values to DT constructor and rendering table view, this provides fast table data filtering and search options data = TicketData.objects.filter(f).values(...) json_data = repr(json.dumps(list(data), default=str)) TicketData object with related fields is big, I can't display all object values in table row, but I'm using them for filtering and search by putting them in hidden block. Each ticket can hold multiple assets and I need to have possibility to search/filter data in table by specific asset values, currently I'm adding them by looping trough all related assets and setting necessary values as new text field for object: for ticket in data: asset_search_data= "" for asset in TicketAssetMap.objects.filter(ticket__id=ticket['id'], edited=True): asset_search_data += str(asset.asset.asset_nr) + " " + str(asset.asset.inventory_nr)+ " " + str(asset.asset.room) + " " ticket['asset_search_data'] = asset_search_data json_data = repr(json.dumps(list(data), default=str)) This approach works, but page load is slow due to many sql requests. I'm thinking to use subquery for main data query, but I cant figure out how to combine queryset in to one text field. asset_data = TicketAssetMap.objects.filter(ticket=OuterRef('pk')).annotate(assets=Concat("asset__asset_nr", Value(" "), "asset__room", Value(" "), output_field=TextField())).values('assets') data = TicketData.objects.filter(f).annotate(assets=Subquery(asset_data)) This will fail as soon as ticket will have more … -

How to create a ldap BIND_DN for samba active directory
I am trying to setup samba active directory users authentication for my Django app. I working in linux. I don't have access to windows active directory. I got a docker image smblds for samba AD DC on Ubuntu 22.04 using docker run --name smblds \ --publish 389:389 \ --publish 636:636 \ --detach smblds/smblds:latest The docker started fine. I can see the smb.conf and other tdb files created. But this docker does not set the BIND_DN value. So, I executed the docker and from inside the smblds docker I provisioned the active directory with samba-tool domain provision --use-rfc2307 --interactive I used all the default settings for Realm, Domain, server role, dns backend and Administrator password I see following messages in the output Setting up self join Repacking database from v1 to v2 format (first record CN=ms-WMI-StringSetParam,CN=Schema,CN=Configuration,DC=samdom,DC=example,DC=com) Repack: re-packed 10000 records so far Repacking database from v1 to v2 format (first record CN=server-Display,CN=409,CN=DisplaySpecifiers,CN=Configuration,DC=samdom,DC=example,DC=com) Repacking database from v1 to v2 format (first record CN=51cba88b-99cf-4e16-bef2-c427b38d0767,CN=Operations,CN=DomainUpdates,CN=System,DC=samdom,DC=example,DC=com) Is any of these a BIND_DN. Actually when I try to connect to active directory using python ldap I see invalid credential error. >>> import ldap >>> ldap_server = ldap.initialize("ldap://172.17.0.5/") >>> ldap_server.set_option(ldap.OPT_X_TLS_REQUIRE_CERT, ldap.OPT_X_TLS_ALLOW) >>> ldap_server.set_option(ldap.OPT_X_TLS_NEWCTX, 0) >>> ldap_server.start_tls_s() >>> … -
Django - pythonanywhere - ProxyConnectionError
I deployed my Django project on pythonanywhere. In the project, I use "storages.backends.s3boto3.S3Boto3Storage" as DEFAULT_FILE_STORAGE. It connects to a cloud storage so that I can upload and save media files on there. It works fine on my local system but on pythonanywhere, it gives this error when a media file is going to be uploaded: ProxyConnectionError Failed to connect to proxy URL: "http://proxy.server:3128" I'm new to this and I don't know what else information is needed on this for someone to answer my question. So let me know to edit my question. -
