Django Inline Formset "update" functionality is not working
Django project: For Create and Update, I used Class Based View method. In there, I have form (parent) and formset (of child). Both ParentForm and ChildFormset are in the same page. Create functionality is working perfectly. Problem: Update functionality is not saving changes because of already existing formset. It only refreshes the current page. How to fix it? class ParentInline(): form_class = ParentForm model = Parent template_name = "parent_create_or_update.html" def form_valid(self, form): named_formsets = self.get_named_formsets() if not all((x.is_valid() for x in named_formsets.values())): return self.render_to_response(self.get_context_data(form=form)) self.object = form.save() # for every formset, attempt to find a specific formset save function # otherwise, just save. for name, formset in named_formsets.items(): formset_save_func = getattr(self, 'formset_{0}_valid'.format(name), None) if formset_save_func is not None: formset_save_func(formset) else: formset.save() return redirect('/parent_list') def formset_childs_valid(self, formset): """ Hook for custom formset saving.Useful if you have multiple formsets """ childs = formset.save(commit=False) # self.save_formset(formset, contact) for child in childs: child.parent_Id = self.object child.save() class ParentCreate(ParentInline, CreateView): def get_context_data(self, **kwargs): ctx = super(ParentCreate, self).get_context_data(**kwargs) ctx['named_formsets'] = self.get_named_formsets() return ctx def get_named_formsets(self): if self.request.method == "GET": return { 'childs': ChildFormSet(prefix='childs'), } else: return { 'childs': ChildFormSet(self.request.POST or None, self.request.FILES or None, prefix='childs'), } class ParentUpdate(ParentInline, UpdateView): def get_context_data(self, **kwargs): ctx = super(ParentUpdate, self).get_context_data(**kwargs) … -
Need help choosing backend end / front end languages (I'm beginner) [closed]
I want to create a website with machine learning logic in python on the back-end and use react on the front-end. I'm going to do everything myself, as I'm a beginner any tip is welcome. So my thought process is to use Django to handle all the python and back-end, and use Next.js for the front-end. I'll create a simple guitar tuner as a starting point, and as I learn new stuff, I'll implement it to the site and create new features for it like some kind of music sheet. Is this the best approach? I want to use these languages because I already know them, do Django and Next.js work well together? Or is using just next.js enough by now? This is just a personal project for now, if I'm satisfied with the end result I will host it somewhere in the future -
Difference between creating indexes in Django using db_index=true and Class Meta: indexes=[ models.Index(fields=[col1, col2,..]),]
I was looking into how to create an index in Django. I came across two ways: Class Student(models.Model): name= models.CharField(........, db_index=True) age= models.CharField(........, db_index=True) Class Student(models.Model): name= models.CharField(........) age= models.CharField(........) Class Meta: indexes = [models.Index(name="first_index",fields=["name","age"],)] Can someone clarify what the difference between them is? Moreover, in the db_index=true method, is there a single index for all the fields with db_index=true ? -
Django LogEntry without user
In my app there's a Project model which users can create, request to join, invite others to join, accept/reject requests/invites to join, leave, etc. I'm using the Django LogEntry to help the application admins keep track of all changes to each Project, but also changes to related objects such as ProjectMember, ProjectMemberRequest and ProjectMemberInvite. Both ProjectMemberRequest and ProjectMemberInvite have expiration dates which means that, if they aren't accepted/rejected within 3 days after being created, the system automatically sets them as 'expired'. How can I log this automatic expiration of ProjectMemberRequest and ProjectMemberInvite, knowing that LogEntry requires a user and this expiration actions are not triggered by a user? A workaround I could use is to create a "System" superuser and log these automatic actions to that user. Is there anything better? -
How to use AWS SES inside Django running in a Fargate container?
I have a Django App running in an AWS ECS Fargate container and want to set up the possibility to send mails from Django. This is not too difficult using the built in function. I have set up SES on AWS and granted the Task Role of my Fargate task full access to SES. As far as I understand, AWS automatically generates credentials for the Task role (see e.g. here. To set up the SES mailing function in Django, I need the EMAIL_HOST_USER which in case of AWS SES will be an AWS_ACCESS_KEY_ID and the Password which would be the secret key of this user. Now I am slightly confused since I actually want to use the Task role of the Fargate task to send emails. Do I have to somehow get the credentials inside the Django code and set the environment variables? Or can I leave them blank and somehow Fargate automatically connects to SES by its Task Role. -

In a django template, how to access dynamically to each attribute for every database table row?
I'm building a table in a django template to show all the records from a database table. I need to build dynamically (both rows and columns) but I am having problems to access each record attribute. My code's result, is an empty table with the same amount of database rows. I created a variable field_name to be assigned the attribute name, and then access that attribute aplying this variable to each record. The result, is an empty table with the same amount of database rows. I printed field_name and the attribute name is assigned okey, but then it's not applied correctly to the record. How should I code it? <tbody> {% for record in table_records %} <tr> {% for field in table_fields %} {% with field_name = field.name %} <td>{{ record.field_name }}</td> {% endwith %} {% endfor %} </tr> {% endfor %} </tbody> -

Django javascript Canvas late update draw
I made a form that calculates a rectangle in Django. I made a form in the html file and had it calculated with javascript and gave the data to the screen.

Django ORM - How to access annotated field value?
Let's assume I have the next models: class A(model): b = models.ManyToManyField("b", through="AB") class B(model): id = models.CharField() class AB(model): a = models.ForeignKey("a") b = models.ForeignKey("b") I want to retrieve all related A objects for specific B object and plus annotated field count_something for each A object. b_obj = B.objects.prefetch_related(Prefetch('ab_set', queryset=AB.objects.select_related('a') .annotate(count_something = Count(....)))) .get(id=<b_id>) I've tried this way, but it does not work a_qs = [ab.a for ab in b_obj.ab_set.all()] for a in a_qs: print(a.count_something) error: "A" object has no attribute 'count_something' What is the correct way to achieve what I want? -
