On which tablet from the following can I code on?
I understand tablets are not a good choice for developers, but out of the following which one can be used for coding? (I'm pretty new at coding, so just some basic languages working should be fine.): SAMSUNG GALAXY TAB A7, Lenevo M10, or Lenevo Tab 4 tablet. Does any of these support mostly used languages and software? -
Django updating One-To-One Relationship is causing UNIQUE Constraint Failure
I cannot wrap my head around why I'm getting an error here - when the update query is run with this django ORM save() code, I get a UNIQUE Constraint Error: django.db.utils.IntegrityError: UNIQUE constraint failed: tasks_recurringtask.id From my understanding, update is executed immediately and only called on the same scheduler job that has the ID referencing the given RecurringTask. Maybe I'm missing something or there is a safe way to do this? Any explanations would be helpful, thanks! class RecurringTask(models.Model): name = models.CharField(max_length=255) owner = models.ForeignKey(CustomUser, on_delete=models.CASCADE, related_name='tasks') start_time = models.DateTimeField(default=now) scheduler_job = models.OneToOneField( Schedule, on_delete=models.CASCADE, blank=True, null=True, default=None ) def save(self, *args, **kwargs): # set all other dependencies for Task # update Scheduler Job if self.scheduler_job is None: self.scheduler_job = Schedule.objects.create(func='tasks.jobs.do_task', args=f'{self.pk}', next_run=self.start_time ) else: Schedule.objects.filter(id=self.scheduler_job_id).update( next_run=self.start_time ) super(RecurringTask, self).save(self) -

Make Column in Pandas Dataframe Clickable and pass text value to Django view
I have a column in a dataframe called State. I want it to be clickable and when clicked, go to a URL and pass the state name to a Django view. So far I have tried it this way: smalldf['state'] = smalldf['state'].apply(lambda x: f'<a href=".\?q={x}">{x}</a>') It creates a url like this: http://127.0.0.1:8000/mysite/?q=TN but I am unable to extract the value TN from inside the view. The Django code looks like this: print('state is : ') print(parm_state) search_form = DateRangeForm(request.POST or None) # if this is a POST request we need to process the form data if request.method == 'POST': date_from = request.POST.get('startDate') date_to = request.POST.get('endDate') I can find the TN state value at the top and can print it. But when I come back from the DateRangeForm the value is gone. I cannot find a way to access it from inside the if request.method == 'POST' code. Would appreciate some help. Thanks -
Created information box inside form, based on model fields
Greetings and Happy Christmas everyone! I'm trying to implement a simple information text based on my model field because it retains some data like: MyModel.information: { start_date: imaginary_date, end_date: imaginary_date, store_name: 'Foo bar' } Now I want to display inside my admin form that information as a text, like: 'Store Foo bar, start at imaginary_date and close at imaginary_date. That implementation is just to the client who is editing some information at the form, can see easily the information about the store. -

Custom format an inline formset
I'm create a template in Django, adding a form and formset to the template, but I don't like how it's formatting the formset by default. I've tried .as_table and .as_ul, but it's not formatting it to my liking. I'd like to see the following from the formset: Ingredient Percentage Delete ingredient1 .55 ingredient2 .22 ingredient3 .33 I've tried the code in "https://stackoverflow.com/questions/17492374/how-to-render-formset-in-template-django-and-create-vertical-table" but when I implement it, I'm getting two extra column, "ID" and "Recipe Name".

Django - How to register route with query parameters?
Im very new to Django, struggling to find the answer Im looking for. Please bear with me. In my app/urls.py file I have router = routers.DefaultRouter() router.register(r'drugs', views.DrugViewSet) In my views.py file I have class DrugViewSet(viewsets.ModelViewSet): queryset = Drug.objects.all().order_by('name') serializer_class = DrugSerializer And my DrugSerializer class looks like class DrugSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Drug fields = ('id', 'name', 'description', 'recommended_dose_mg', 'count', 'create_date', 'update_date') So when I do a GET on /drugs, I correctly get the list of drugs. And when I take a UUID (primary key) on a specific drug and do a GET on /drugs/<primary_key>, it correctly pulls the specific drug. However, I want the GET on /drugs/<primary_key> to display different data. I want to join it with another model that I have and return a new json response. How exactly would I do this? -

My app structure looks like this: app/ admin.py apps.py models.py (this contains my Article model) views.py file_where_ihave_my_error.py -
Django NEWBIE - TemplateDoesNotExist
(My project directory is called test and the app in question is called posts) Django tried loading these templates, in this order: Using engine django: django.template.loaders.app_directories.Loader: /path-to-app-dir/virtual/test/posts/templates/index.html (Source does not exist) django.template.loaders.app_directories.Loader: /path-to-app-dir/virtual/platform/lib/python3.10/site-packages/django/contrib/admin/templates/index.html (Source does not exist) django.template.loaders.app_directories.Loader: /path-to-app-dir/virtual/platform/lib/python3.10/site-packages/django/contrib/auth/templates/index.html (Source does not exist) Views.py from django.shortcuts import render from django.http import HttpResponse def index(request): return render(request,'templates/index.html') Urls.py from django.urls import path from . import views urlpatterns=[ path('', views.index) ] I have mentioned the app in Settings.py so that probably shouldn't be an issue. What am I doing wrong ? -
Интеграция данных парсера с Django [closed]
Я хочу сделать сайт, на котором можно будет посмотреть информацию о разных вузах. У меня готовы парсеры, но я не понимаю, как можно правильно интегрировать парсеры в Django приложение... Когда я искал информацию по этому поводу, одним рекомендовали использовать django-admin команды, другим использовать парсеры. Я не понимаю, что использовать лучше, у чего какие плюсы и что стоит в итоге выбрать? На данный момент у меня парсеры заливают информацию в стороннюю бд и через класс вытягивается в html форму. Не думаю, что это правильное решение...
