How to use django-admin-sortable2 and django-import-export package together in admin panel?
I want to use django-admin-sortable2 django-import-export package together in admin panel. Here is the code: class University(models.Model): name = models.CharField(max_length=50, help_text="University or Institution Name") short_name = models.CharField(blank=True, max_length=10, help_text="University or Institution Short Name") order = models.PositiveIntegerField( default=0, blank=False, null=False, ) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) def __str__(self): return f'{self.id}-{self.name}' class Meta: ordering = ['order'] admin.py: from import_export import resources from import_export.admin import ImportExportModelAdmin from adminsortable2.admin import SortableAdminMixin # Register your models here. class UniversityResource(resources.ModelResource): class Meta: model = University exclude = ('created_at', 'updated_at',) class UniveresityAdmin(ImportExportModelAdmin, SortableAdminMixin, admin.ModelAdmin): resource_classes = [UniversityResource] admin.site.register(University, UniveresityAdmin) But this is not working, If I remove ImportExportModelAdmin then sortable works and if I remove SortableAdminMixin, import-export works. But I want to use both package together. Is there workaround to solve this issue? Thanks in advance. -
My Django project is not displaying some components, I've tried everything but it's not working [closed]
So I have this resume builder web app project, and it has an experiences section. In the experiences, I have main experience and additional experiences. Whereby in a form, a person enters their experience, and if they have additional experiences, they click the "additional experiences" button and add more experiences. However when I visit preview page, the additional experiences are not displaying, only the main experiences are displaying. models.py: class experience(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE, default=1) position = models.CharField(max_length=200) company = models.CharField(max_length=200) startdate = models.DateField() enddate = models.DateField() roles = models.TextField(max_length=500) is_main_experience = models.BooleanField(default=False) views.py: # Create experiences @login_required def experience_v(request): if request.method == 'POST': position = request.POST['position'] company = request.POST['company'] startdate = request.POST['startdate'] enddate = request.POST['enddate'] roles = request.POST['roles'] main_experience = experience(user=request.user, company=company, position=position, startdate=startdate, enddate=enddate, roles=roles) main_experience.is_main_experience = True main_experience.save() return redirect('education') else: form = ExperienceForm() return render(request, 'experience.html', {'form': form}) # Create additional experiences def addexperience_v(request): if request.method == 'POST': additional_experience_positions = request.POST.get('additional_experience_position') for i in range(len(additional_experience_positions)): additional_experience_position = request.POST.get('additional_experience_position[' + str(i) + ']') additional_experience_company = request.POST.get('additional_experience_company[' + str(i) + ']') additional_experience_startdate = request.POST.get('additional_experience_startdate[' + str(i) + ']') additional_experience_enddate = request.POST.get('additional_experience_enddate[' + str(i) + ']') additional_experience_roles = request.POST.get('additional_experience_roles[' + str(i) + ']') additional_experience = experience.objects.create( user=request.user, position=additional_experience_position, … -
HTTPConnectionPool Max retries exceeded with url" Error in Python Selenium
I have a web application where users can perform searches on specific retailers and view the results in tables.

django-ses: Connect timeout when using django.core.mail
I am using django-ses==3.4.1 to send email via django.core.mail and both send_mail() and EmailMessage() get the connection timeout after one minute: botocore.exceptions.ConnectTimeoutError: Connect timeout on endpoint URL: "https://email-smtp.eu-central-1.amazonaws.com/ Using this configuration in settings.py according to the instructions on https://pypi.org/project/django-ses/ EMAIL_BACKEND = 'django_ses.SESBackend' AWS_SES_USER = 'my-verified@email' AWS_SES_ACCESS_KEY_ID = '-my-access-key-' AWS_SES_SECRET_ACCESS_KEY = '-my-secret-access-key-' AWS_SES_REGION_NAME = 'eu-central-1' AWS_SES_REGION_ENDPOINT = 'email-smtp.eu-central-1.amazonaws.com' Where I use the variable AWS_SES_USER as from_email while calling email = EmailMessage(subject, message, from_email, recipient_list) email.content_subtype = 'html' email.send() I have also tested if the SES works without Django, i.e. simply using smtplib and it does.

Understanding PromQL in grafana dashboard
I am trying out django dashboards for grafana. I imported a django dashbord from grafana.com. It has following panel: (I have greyed out my app view names) The PromQL query is as follows: topk(20, (1 - (sum(max_over_time(django_http_requests_latency_seconds_by_view_method_bucket{app=~"^$application$",le="$threshold"}[$__range]) / ignoring(le) max_over_time(django_http_requests_latency_seconds_by_view_method_count{app=~"^$application$"}[$__range])) by (method, view) / count(present_over_time(django_http_requests_latency_seconds_by_view_method_count{app=~"^$application$"}[$__range])) by (method, view))) > 0.0099) Also, the bar gauge does not change as long as I select "Last X", i.e. from "Last day" to "Last Year". Q1. Is it because all data is generated in last day it is convered in "Last Year" and the query takes Max over whole range? Q2. Can someone help me understand this PromQL? Is it returning slowest view in given time range? Q3. Also what is ">1s" in its title bar? -
Vue.JS + Django issue, it wouldn't let me update my userprofile from the dashboard(I get no errors, yet my database doesn't update)
So I am working on this time tracking app for myself, to learn Django and Vue.js, I found a tutorial from Code with Stein. I got stuck at editing the profile part from the tutorial. I get no errors, yet there are no changes made to my username or email(the changes don't even apply to my admin dashboard or database). The thing is that I get no error, which leaves me completely in the dust. I used Python, Django, Vue.JS, and soon SaaS if I find a resolution for this issue.

DJANGO non nullable field migration issue
Im a DJANGO/python novice. I have added two fields so that changes in enterprise and DJANGO admin are logged as who updated them and what date it was updated. the constraint is that these fields cannot be null. my changes are as follows: class Enterprise(models.Model): last_updated = models.DateTimeField( null=False, auto_now=True, verbose_name='Last Updated Date', help_text="Points to time this was last modified", ) last_updated_by = models.CharField( null=False, max_length=100, default='N/A', ) AND class EnterpriseAdmin(admin.ModelAdmin): model = Enterprise readonly_fields = ( "last_updated", "last_updated_by",) fieldsets = ('last_updated','last_updated_by',), however when I run pytest, I'm receiving an error: null value in column "last_updated" violates not-null constraint. when I ran makemigrations, Django prompted me to add a default for last_updated: You are trying to add a non-nullable field 'last_updated' to enterprise without a default; we can't do that (the database needs something to populate existing rows). Please select a fix: 1) Provide a one-off default now (will be set on all existing rows) so I chose option '1' and default=datetime.datetime(1970, 1, 1, 0, 0),preserve_default=False, is added to last_updated in my migration file. migrations.AddField( model_name='enterprise', name='last_updated', field=models.DateTimeField(auto_now=True, default=datetime.datetime(1970, 1, 1, 0, 0), help_text='Points to time this was last modified', verbose_name='Last Updated Date'), preserve_default=False, ), I was under the impression … -
Tastypie queries for all fields, is it possible to only SELECT specific fields
With tastypie you create a resource for your Django model and point the queryset at your model.objects.all(). I was expecting "fields" to allow me to declare which fields i want to return: https://django-tastypie.readthedocs.io/en/latest/resources.html?highlight=exclude#fields This does work, but the sql query generated doesnt care it selects all fields. For me this seems a bit bit pointless if im querying a large table and only want to return 2 columns, and not the other 8. Hopefully I've missed something obvious in the TP documentation. If anyone has any pointers/ideas that would be great -
creating tags during post creation works, but using existing ones don't - possible problem with serializer or something else
I am trying to write a code that will make it able to create tags during creating post and use tags created by urself, other users earlier. I think thats a common approach. This test works without a problem, because it creates a tag during post creation: class TagTests(TestCase): """Tests for tags.""" def setUp(self): self.client = APIClient() self.user = User.objects.create_user(email='mail@example.com', password='password123') self.client.force_authenticate(self.user) self.admin = User.objects.create_superuser(email='admin@example.com', password='password123') self.post = Post.objects.create(user=self.user, text='Test post') self.tag1 = Tag.objects.create(user=self.user, name='Existing Tag 1') self.tag2 = Tag.objects.create(user=self.user, name='Existing Tag 2') self.url_post = reverse('posts-list') def test_create_tags_during_post_creation(self): """Test creating tags during post creation.""" payload = {'text': 'Test', 'tags': [{'name': 'tag1'}, {'name': 'tag2'}]} res = self.client.post(self.url_post, payload, format='json') post_id = res.data['id'] post = Post.objects.get(id=post_id) tags = post.tags.all() tag_names = set(tag.name for tag in tags) self.assertEqual(res.status_code, status.HTTP_201_CREATED) self.assertIn('tag1', tag_names) self.assertIn('tag2', tag_names) However I cannot get my next test to work, because it returns error 400 and response is {'tags': [{'name': [ErrorDetail(string='tag with this name already exists.', code='unique')]}, {'name': [ErrorDetail(string='tag with this name already exists.', code='unique')]}]} def test_create_post_with_existing_tags(self): """Test creating post with existing tags.""" payload = {'text': 'Test post creating with existing tags', 'tags': [{'name': 'Existing Tag 1'}, {'name': 'Existing Tag 2'}]} res = self.client.post(self.url_post, payload, format='json') print(res.data) self.assertEqual(res.status_code, status.HTTP_201_CREATED) post_id = … -
Django: Attach passed id to instance?

What is currently a good approach to input masks when using Django model forms?
I'm trying to find out what the best current approach is for input masks in Django when using model forms. I have tried: https://dobsondev.com/2017/04/14/using-jquery-mask-to-mask-form-input/ and https://imask.js.org/guide.html#masked-number but both approaches require that I catch the postback and remove the masking to prevent the model form validation from failing. I can't help but wonder if there is a more eloquent approach/plugin. -
Unit Test for a QuerySet class
I need to unit test a queryset class.

Since my_method uses self.annotate and import within the method, things get harder.

How to deal with multi-page react application with django?
Has anyone built a multi page react app using ReactJS, Django and Django-REST. I have a good idea on how to achieve it. But the problem i want to build a multi html page app with ReactJS. There will be some endpoints which deliver HTML and others which deliver API data. For delivering HTML, i will use Django templates and for API data i will use DJango-REST. I can make a GET request for an HTML page from a react component with Axios, but the problem is i will need a way to render this HTML response from the frontend. My plan is to rewrite the DOM using document.write(ReturnedHTML). Will there be any potential performance problems with this approach?

Django custom model field do work after save
I've got a custom model field class VaultField(CharField): which is used like: class MyClass: secret = VaultField(max_length=200, blank=True) It should save that field's value to HashiCorp Vault and store the Vault path in the database. That's all nice and easy when the Vault path is static, but what I'd like to do is to build the Vault path based on the model instance ID. But none of the methods from_db_value, to_python, get_prep_value are being called post save and therefore don't have any data about the instance. Is there any way to run field code post save? To get the path /fields/[my-class-name]/[my-class-id].
