Form is submitted but not saving value in database
When I submitted this form, instead of saving the value it takes and save it to the database, it submitted the form but the value is none when I check admin page, the form is submitted and redirected me to home page, but the value that a form takes is none when I check my admin: Model: class Column(models.Model): user = models.OneToOneField(User, on_delete= models.CASCADE) name = models.CharField(max_length=100) select_type = models.ForeignKey(Type, on_delete= models.CASCADE) views: class CreateColumn(CreateView): model = Column template_name = 'column_create.html' form_class = ColumnForm success_url = 'home' def get_context_data(self, **kwargs): context = super(CreateColumn, self).get_context_data(**kwargs) context['formset'] = ColumnFormSet(queryset=Column.objects.none()) return context def form_valid(self, form): form.instance.user = self.request.user return super(CreateColumn, self).form_valid(form) Form: class ColumnForm(forms.ModelForm): class Meta: model = Column fields = ['name', select_type'] ColumnFormSet = modelformset_factory(Column, fields=('name' 'select_type'), extra=30) template: <form method='post'> {% csrf_token %} {{ formset.management_form}} {% for form in formset %} {{form.as_p}} {% endfor %} <button type='submit'>Save<button/> <form/> -

admin.display with mark_safe
Is there any chance I can put HTML in the <th> of change_list.html, other than going down the ugly road of overriding the admin_list template tags? I want to style the text in the table head a little bit for viewing pleasure but it is quite tricky to access the table header in django. I have something in mind like: @admin.display(description = mark_safe("<b class='bg-danger'>status</b>")) def get_status(self, obj): return obj.status -

How do I pass in a variable inside a HTML link which will then pre populate different parts of a fields in my Django model form
Please bare with me as this is my first post on here and I may have made some formatting erros in the way the question is presented and someone might have already answered my question. But I just can't find the answer. Thank you very much for your help in advance. So I have a Django project that shows a weekly calender with items that people will be working on.

How to implement feature flags efficiently for a backend?
Doesn't matter it is a web app or api, we need feature flags. If we don't need separate flags per user groups, the same flags works on all site. We don't update these flags too frequently. In this situation there are some options to store this flags. I believe the effects are similar for any framework such as Django, NodeJs, Rails, Spring. Database: We can store the flags in database, but the drawback it that, each time we access to a flag, it connects to database. Database + Application Constants: Application can read and cache the flags at the boot time. The drawback is that when we update a setting we have to restart all processes. Redis: Faster than database but the management is more hassle. SaaS Service: The slowest one because it works with connections to outside. Environment variables: Works native but updating them is not comfortable process, plus requires restart. I am curious if someone uses a way better than those. Or a technique removes the drawback. Thanks. I am looking the best way to implementing feature flags. -

Looking for alternatives to Celery for running background tasks
I'm building an application using Django Rest Framework. One of the requirements is to initiate/maintain background tasks that will continuously monitor some cloud instances and update the database. For this, I used Celery in the way of creating Celery tasks via DRF code. However, it didn't help on long run since Celery was not able to scale up and became unstable. So, please suggest any alternate software/ methodology to accomplish the task. Thanks -
