Django - Prefill admin creation form with inline forms
I'm trying to create a form in Django admin, that, when you create a new entry, will take the latest entry, and fill the new entry with that data. E.g. (Book and Author are just examples) class Book(models.Model): id = models.Autofield(primary_key=True) author = models.ForeignKey(Author, on_delete=models.CASCADE) name = models.Charfield(max_length=200) class Author(models.Model): id = models.Autofield(primary_key=True) name = models.Charfield(max_length=200) I then added this to the admin page: class BookInline(StackedInline): model = Book extra = 0 class AuthorAdmin(ModelAdmin): inlines = [BookInline] admin.site.register(Author, AuthorAdmin) Now when I create a new Author, I want the form to be filled in with the last created author and his books So if said author had 5 books, it would now fill this form with the name of that author, and also add the 5 books. I was able to fill the author form by adding this to the AuthorAdmin class: def get_changeform_initial_data(self, request): return model_to_dict(Codebook.objects.all().get())#Temp But the books are not filled this way. Is it somehow possible, to pass the books into the inline forms? (Running Django 3.2 and Python 3.9) -
Correct way to add dynamic form fields to WagtailModelAdminForm
I have a use case where I need to add dynamic form fields to a WagtailModelAdminForm. With standard django I would normally just create a custom subclass and add the fields in the __init__ method of the form. In Wagtail, because the forms are built up with the edit_handlers, this becomes a nightmare to deal with. I have the following dynamic form: class ProductForm(WagtailAdminModelForm): class Meta: model = get_product_model() exclude = ['attributes', 'state', 'variant_of'] def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) if self.instance: self.inject_attribute_fields() def inject_attribute_fields(self): for k, attr in self.instance.attributes.items(): field_klass = None field_data = attr.get("input") field_args = { 'label': field_data['name'], 'help_text': field_data['help_text'], 'required': field_data['is_required'], 'initial': attr['value'], } if 'choices' in field_data: field_args['choices'] = ( (choice["id"], choice["value"]) for choice in field_data['choices'] ) if field_data['is_multi_choice']: field_klass = forms.MultipleChoiceField else: field_klass = forms.ChoiceField else: typ = field_data['attr_type'] if typ == 'text': field_klass = forms.CharField elif typ == 'textarea': field_klass = forms.CharField field_args['widget'] = forms.Textarea elif typ == 'bool': field_klass = forms.BooleanField elif typ == 'int': field_klass = forms.IntegerField elif typ == 'decimal': field_klass = forms.DecimalField elif typ == 'date': field_klass = forms.DateField field_args['widget'] = AdminDateInput elif typ == 'time': field_klass = forms.TimeField field_args['widget'] = AdminTimeInput elif typ == 'datetime': field_klass = forms.DateTimeField … -

Send data in a complete tree structure using django serializers
I have 2 models: Folder and Entity. class Folder(models.Model): name = models.CharField(max_length=255, null=False, blank=False) parent = models.ForeignKey('self', on_delete=models.SET_NULL, null=True, blank=True, related_name="child") class Entity(models.Model): name = models.CharField(max_length=255, null=False, blank=False) folder = models.ForeignKey('Folder', on_delete=models.SET_NULL, null=True, blank=True, related_name="entities") So a folder can have both child folders and entities. Now I want to send the data in a tree structure and I have written a serializer for it. class ListFolderSerializer(serializers.ModelSerializer): children = serializers.SerializerMethodField() class Meta: model = Folder fields = ['id', 'name', 'children'] def get_children(self, instance): child_folders = Folder.objects.filter(parent=instance).order_by("name") child_entities = Entity.objects.filter(folder=instance).order_by("name") all_children = [] if child_folders or child_entities: child_folders_data = ListFolderSerializer(child_folders, many=True).data child_entities_data = ListEntitySerializer(child_entities, many=True).data all_children.extend(child_folders_data) all_children.extend(child_entities_data) return all_children else: return None class ListEntitySerializer(serializers.ModelSerializer): class Meta: model = Entity fields = ['id', 'name'] This is working fine but as the data keep on increasing the time to get this tree is increasing. So any optimized way to do this? -
Display records with respect to their id's in Django
My Django application includes a page named list in which list creates against a user to after analysis of .pcap file: The problem is I want to display the results on the basis of id in hash table. The id in hash_mod table has one to many relationships. Therefore, It'll be easy for me to fetch the results on the basis of id. How I will use the primary key (id in hash_mod) table to link through foreign key (hash_id in demo) table to fetch the results. I have also share the image url to view the list.html what it looks like. In list.html there is a button named "View" which is using the post method. There is for loop in list.html which recognize the total number of files analyzed by a user. When a user will analyze a file an id and hash will create in "hash_mod" table which I have mentioned below. Id will treat as a foreign key in another table, so I want to fetch the result witch respective to their primary key id and foreign key id. if anyone have still problem to understand the question anyone can ask. But please don't give a negative … -

Pylint is not able to locate the model in the context of the views.py file
I'm using VSCode and the Pylint that ships with it, i.e., no extension. Everything has been running smooth for many months and I've never had an issue with Pylint presenting weird alerts. I recently started learning Django and today when following the official Django Documentation tutorial part 4 pylint could not recognize a couple of statements related to a model. Pylint can't recognize the (choice_set) method below selected_choice = question.choice_set.get(pk=request.POST['choice']) Pylint can't recognize (question.id) below return HttpResponseRedirect(reverse('polls:results', args=(question.id,))) The errors I get from pylint are below choice_set: Unknown Cannot access member "choice_set" for type "Question" Member "choice_set" is unknownPylancereportGeneralTypeIssues and id: Unknown Cannot access member "id" for type "Question" Member "id" is unknownPylancereportGeneralTypeIssues At first I thought the issue might've been I'd forgot to cross reference the Question and Choice models, but this is not the case.

Django database object save() fails silently [closed]
I have a bug which is not reproducible and occurs rarely. Get object of the database: db_obj= My_Db_Model.objects.get(ID=id_from_param) # called always with same id_from_param Modify fields like: db_obj.value = 123 db_obj.save() No. 3 is surrounded by try, except (Exception), which means it applies for all exceptions and it should log the exception. Most of the times it works, but sometimes the value is not updated, without having any exception. Could there be some explanation how this could happen and under which circumstances it could fail silently like this? It is a postgresql database and I was also not able to figure out something from the database logs. Maybe there is a way to check if the database works correctly? -
