I have a point awarding method in my website and I want to create a "top users in last 10 days" list. right now I store and update user scores in Profile model which is: class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, null=True) points = models.IntegerField(default=0) but I want to get the value of this "point" instance at for example 10 days ago for comparing it to latest value. how can I achieve this? -

Django permissions analysis
Is anyone aware of a programmatic way of analysing a codebase to see which permissions each view is protected by? I'd like to be able to run a regular report on a site to inform us which views are available and who can see them etc. rather than having to maintain a list by hand. I'm aware of the show_urls command from django-extensions but that doesn't help with the permissions side of things. -
django date filter doesn't update
I made a listview in a django project. But when day go away, filter stay on starting data (start or refresh of web-server). Why it doesn't update every day? this is my code: (table booking for restaurant) models.py: class Table_book(models.Model): name = models.CharField(max_length=50) date = models.DateField() time = models.CharField(max_length=50, choices=TIMES) people = models.PositiveIntegerField(choices=TABLES) telephone = models.CharField(max_length=50) views.py class List_book(ListView): model = Table_book template_name = 'list_today.html' queryset = Table_book.objects.all().filter(date=timezone.now()).order_by('date', 'time') urls.py url(r'^$', login_required(List_book.as_view(), login_url='/login/'), name='home'), in template.html the list objects populate a table. -
django - How to make a custom is_authenticated to verify if a user is connected?
I have a custom user model using AbstractBaseUser, called Users, so I also have a custom authentication backend: https://pastebin.com/waky5AW3 My issue is that I don't know how to check if a user is connected while using this custom user model, because users.is_authenticated will always return true as logged in and user.is_authenticated will always return false and I mean not logged in, ONLY if the user is logging into the CONTROL PANEL, THEN, user.is_authenticated will return TRUE and which means that the user is LOGGED in. This is how I log in the user once form is submitted: email = form.cleaned_data['email_field'] password = form.cleaned_data['password'] temp = OwnAuthBackend() user = temp.authenticate(email=email, password=password) if user is not None: messages.success(request, 'You logged in successfully!') return redirect('index', users = user) The if is not None returns true and the user is redirected to the index with variable users = user and with that success message, and I know it is not a good way because if user comes from another redirect, still logged in but without the variable 'users', it should give him an error. The thing is, How to check if user is authenticated using a custom user model... -

I think I'm installing Django, but it doesn't seem to be there
Mysterious. I may not understand virtualenv sufficiently to use it. I created what I thought was a virtual environment: pip3 -m venv myenv pip3 install --ignore-installed django~=2.0.0 Collecting django~=2.0.0 Using cached Django-2.0.1-py3-none-any.whl Collecting pytz (from django~=2.0.0) Using cached pytz-2017.3-py2.py3-none-any.whl Installing collected packages: pytz, django Successfully installed django-2.0.1 pytz-2017.3 001b639f6f87:myenv admin$ ls bin include lib pyvenv.cfg So, where is Django? Actually, this may not be a virtualenv question. Run the same command in a non-venv directory with the same result: no Django. So, I think, maybe there is an issue with Django 2.0 of which I am unaware.

djangocms integration filer_image with apphook objects
I want to add filer_image field to my Gift class instance object. It works as apphook in django-cms. The main problem is that after making migrations and open the view where the form is i don't have loaded js. I already added all tags: {% load staticfiles i18n cms_tags sekizai_tags menu_tags thumbnail filer_tags filer_image_tags %} The model is: class Gift(models.Model): filer_image = FilerImageField(related_name="book_covers") The form: class GiftForm(ModelForm): class Meta: model = Gift fields = '__all__' widgets = { 'name': forms.TextInput(attrs={'class': 'basic-input full-width'}), } The rendered output: Please tell me what am I doing wrong with these. It seems to me like some js files are not loaded. After click it opens FileImageFiler gallery, but I also cannot select any image. -
Restructuring json response from Django REST Framework
My current response which lists all fields in my serialiser is as follows: GET /conversations/<id>/messages returns: { "count": 2, "next": null, "previous": null, "results": [ { "task_id": 21, "conversation_id": 1, "sender": 2, "body": "Hello There" }, { "task_id": 21, "conversation_id": 1, "sender": 2, "body": "Can you do the task" } ] } Instead, since conversation_id , task_id and user_id are repeated, I would like to take them outside the main response. I want to return: { "count": 2, "next": null, "previous": null, "task_id": 21, "conversation_id": 1, "user_id": 1, "results": [ { "sender": 2, "body": "Hello There" }, { "sender": 2, "body": "Second Message" }, ] } serializers.py class MessageSerializer(serializers.ModelSerializer): sender = serializers.ReadOnlyField(source='sender.id') task_id = serializers.SerializerMethodField() conversation_id = serializers.SerializerMethodField() def get_task_id(self, obj): task = Task.objects.filter(task_worker__conversation__message=obj)[0] return task.id def get_conversation_id(self, obj): conversation = Conversation.objects.filter(message=obj)[0] return conversation.id class Meta: model = Message fields = ['task_id','conversation_id','sender','body'] -
How to set interrelated Django model Fields
I have the following simplified problem. Say that I have two Django models, namely a (P)roject and (H)ourly which stores hourly values for the project. Now lets assume that there is a simple relation between these entities, e.g.: H.y = 2*H.x + P.par. Is there an elegant way to implement this? Where to put the help function: def calc_y(x, par): return 2*x+par class P(models.Model): par = FloatField() class H(models.Model): p = models.ForeignKey(P, on_delete.CASCADE) x = FloatField() y = FloatField() -
Sending audio AND text using django to android app

Django rest api expected string or buffer on PATCH

Django admin add model page. Display objects with only foreign key
I have a Django admin page that displays a list of my model, Event, and allows me add an Event. My Event model has a field with a one to many relationship with a field from another model, Church. My problem is that when I go to add an Event, it allows me to add any church I want. Instead I would like to only return churches filtered by id. This is what I have so far: class EventAdmin(admin.ModelAdmin): exclude = () list_display = ('title', 'start_time', 'end_time') def formfield_for_foreignkey(self, db_field, request, **kwargs): if db_field.name == "church": kwargs["queryset"] = models.Event.objects.filter(church__parish=request.user.userprofile.associated_parish) return super(EventAdmin, self).formfield_for_foreignkey(db_field, request, **kwargs) request.user.userprofile.associated_parish is the id I'm searching on. This returns me an empty list of churches so I am affecting the field, but I'm not sure where it's failing. -

Djanog Override Default ModelForm Input Wrapper
There are many questions and answers out there for override the widgets and other field properties on a Django Form. My answer is slightly different from what I have been able to find by searching. Inside my form template, I load the form UI elements like this: <form method="post" enctype="multipart/form-data"> {% csrf_token %} {{ form.as_p }} <a class="button icon fa-cancel" href="{% url 'advertising:my-ads' %}">Cancel</a> <button type="submit" class="button icon fa-save">Save</button> </form> All form elements are rendered wrapped in a <p> element. Like this: <p><label for="id_title">Title:</label> <input id="id_title" maxlength="100" name="title" type="text" value="Flamingo T-Shirt Corporation"></p> So my question is: how to change that <p> element to something else? For example i'd like to change it to <div class='some-class'>. Instead of just hard-coding my own HTML template, I would rather override some aspect of the form class. Here is my current form class defnintion: class AdForm(forms.ModelForm): class Meta: model = Ad fields = "__all__" exclude = ['created','modified'] I'm been reading through the docs and still haven't quite found what I am looking for. Any help is greatly appreciated. -
