Getting objects of many to many to one to many
I have a User model, with a ManyToMany relation with a Department model (so, 1 user can be in multiple departments and 1 department can have multiple users). I also have another model, let's call it "Object". 1 department can have multiple objects, but 1 object can belong only to 1 department. What is the optimal way of getting a list of all object IDs from all the departments that a user belongs to? I mean, sure, I can fetch all departments of the user, and then iterate over each department and fetch all the objects, but I really don't think that is optimal. -

Django - passing variable to javascript file within same script tag
I am trying to pass my variable from Django's view to a javascript file. I read the stack question here (How can I pass my context variables to a javascript file in Django?) to get a few guidance but I am trying something a little bit different. I want to pass variable to the javascript file within that particular javascript reference script tag or changing the order of variable declaration. It is easier to show by example: My somerandom.js: console.log(variable); What works: {% extends base.html %} {% load static %} {% block body %} <h1> Hello, World! </h1> {% endblock body %} {% block javascript %} <script> var variable = {{ my_var }}; </script> <script src="{% static "app1/bootstrap/js/somerandom.js" %}"></script> {% endblock javascript %} What doesn't work: 1: {% extends base.html %} {% load static %} {% block body %} <h1> Hello, World! </h1> {% endblock body %} {% block javascript %} <script src="{% static "app1/bootstrap/js/somerandom.js" %}"></script> <script> var variable = {{ my_var }}; </script> {% endblock javascript %} 2: {% extends base.html %} {% load static %} {% block body %} <h1> Hello, World! </h1> {% endblock body %} {% block javascript %} <script src="{% static "app1/bootstrap/js/somerandom.js" %}"> var variable … -
Django admin inline table not posting values to one to one relationship
sorry for the convoluted question but I am a uni student who has been thrown into the Django framework without any training and I'm doing my best to understand all this in a short time. I really enjoy Django but just can't figure out one problem I'm having. So for the assignment, I need to extend the default admin users table to include more fields. This is what i've done: models: class UserInfo(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) userTypeID = models.ForeignKey(UserType) dob = models.DateField() contactNumber = models.IntegerField() address = models.CharField(max_length=50) @receiver(post_save, sender=User) def create_profile(sender, instance, created, **kwargs): if created: UserInfo.objects.create(user=instance) UserInfo.save(instance) @receiver(post_save, sender=User) def save_user_profile(sender, instance, **kwargs): instance.userinfo.save() def __str__(self): return str(self.user) admin: class UserInfoInline(admin.StackedInline): model = UserInfo class UserAdmin(UserAdmin): inlines = (UserInfoInline, ) admin.site.register(UserType) admin.site.register(City) admin.site.unregister(User) admin.site.register(User, UserAdmin) This brings up the extra fields in the admin panel which is what i was looking for. However, when i try to add a new user and I select one of the userTypes (the OneToOneField), I get: IntegrityError at /admin/auth/user/add/ (1048, "Column 'userTypeID_id' cannot be null") Now I understand my 'Signal receivers' (as I understand them to be) are missing something to handle this but I am unsure as to what.

How do I pre join data for django web application
On my iOS app, when a user logs in I start a series of firebase listeners for my users data... Profile, Accounts, Campaigns, etc.. How and where would I do something like this is django/python? I have a firebase db. I configure it in the top of my views.py, I log the user in on my login view. At this point in the iOS app, I add it to an AppState File and can call it from any view. In django, I ended up calling the data and creating my "joins" in the actual view like so: campaign_list = [] results = db.child('campaigns').get(refresh_token) for campaign in results.each(): campaign = models.Campaign().db_snapshot(campaign) result = db.child('accounts').child(campaign.userUUID).get(refresh_token) campaign.account = models.Account().db_snapshot(result) Now I have my campaign object and attached the account object. db is set from the config at the top of my views.py. I believe this the correct way? I know its weird to use firebase and django, and I'm slowly switching to postgresql, but in the mean time, I have to continue to use firebase. So how do I create a so called snapshot of my user, then access the data when they visit specific views. Aka, create a list of accounts, then … -

Cache-Control not being set in response header
I am trying to optimize my Django web application by leveraging browser caching. I set a Cache-Control header for max-age equal to a year in my home view function returned response. When I load up my site however, and check the response header of some of the images on my home page, the cache-control header isn't there. I tried two different methods of setting the response header. First I tried using Django's built in cache-control decorator. I also tried simply taking the rendered response, and setting the header in my view function before its return statement. Are static images cached differently ? View Function def view_home(request, page=None): # FIND THE HOME PAGE IF WE DO NOT HAVE ONE # IF NOT FOUND RETURN 404 if not page: try: page = WebPage.objects.get(template='home') except WebPage.DoesNotExist: raise Http404 try: billboards = Billboard.get_published_objects() except Exception as e: logging.error(e) billboards = None project_types = ProjectType.get_published_objects() budgets = Budget.get_published_objects() deadlines = Deadline.get_published_objects() contact_descriptions = ContactDescription.get_published_objects() contact_form = ContactForm(type_list=project_types, budget_list=budgets, deadline_list=deadlines, description_list=contact_descriptions) context = {'page': page, 'billboards': billboards, 'contact_form': contact_form} set_detail_context(request, context) template = 'home.html' # Add Cache control to response header expiry_date = datetime.datetime.now() + datetime.timedelta(days=7) response = render(request, template, context) response['Cache-Control'] = 'max-age=602000' response['Expires'] = … -

Django: how to give 'pending-authorization status' and manually authorize user through admin after signup
I'm building a service that targets specific group of people. So I need to evaluate user's signup form and allow only qualified users to login to our website. I first thought about using is_active field in default user model, but then again this field is normally used to filter deleted accounts I thought about implementing the signup process like the following: Allow user to signup Create a pending-auth group with NO permissions for the just signed-up users, who are waiting for authorization Evaluate the users qualifications If qualified, the user from the 'pending-auth' group; this should allow user to login and proceed. How do you think about this? Is this a good way to implement the signup process? I have no idea if this is the CORRECT way to handle my needs. Thanks in advance for the advance! -
Nested filters in a Django app
I have the next model in my Django App: class Value(models.Model): entity = models.ForeignKey('Entity',on_delete=models.CASCADE, related_name='entity') variable = models.ForeignKey('Variable',on_delete=models.CASCADE, related_name='variable') value = models.FloatField(default=0) Now, I need to filter all the "Value" objects where variable "A" is less than 20, and variable "B" is less than 4, for example. I'm trying to filter in this way, but is not working (and variables and values are dynamic and the user can select their combination in the View): entity_list = Value.objects.all().filter(variable__symbol='A', value__lte=20) entity_list = entity_list.objects.all.filter(variable_symbol='B', value_lte=4) Thank you in advance. -

Geodjango, sort results by distance and show the distance explicitly in KM
I currently sort results by distance for my model using: views.py SearchPoint = Point(long, lat) res = Model.objects.filter(location__distance_lte=(SearchPoint, D(m=2000))) .annotate(distance=Distance('location', SearchPoint)).order_by('distance') This allows me to sort the results by distance which are within 2000m. Now I would like to also display the distance between the searcher which is given by SearchPoint and results of my Model. Models.py In my model class I define the following property: # @property # def distance_to_searcher(self): # distance =self.location.distance(SearchPoint) # return distance * 100 I get the following error: name 'SearchPoint' is not defined I understand that this is not defined, because it gets defined in the views.py file, which is a GET request and take long and lat parameters from the URL and puts them into Point() class. Ideally, I would round up the distance to a nice number. -
Django reverse proxy server CORS
I am looking to write a route that works exactly like this https://github.com/Rob--W/cors-anywhere in django I'm thinking it's similar like in this question Django as reverse proxy My question is how to add cors headers into it.

How do you give a wagtail/django Page a custom url to serve at?
In wagtail/django how do you make a basic wagtail Page model, create the html template, and then tell that model to serve as a view for a specific url? from django.db import models from wagtail.wagtailcore.models import Page class MyPage(Page): title = models.CharField(blank=True, null=True, max_length=255) #... I want the url to register like url(r'^monkey/(?P<slug>[A-Za-z0-9]+)$', ...) But I don't have a common urls.py folder its stored outside of the project. I tried using the RoutablePageMixin, but I believe that serves for subpages. I also know where you store the html template within the structure so that is no problem. -
Django: Why am I getting a Value Error?
The variables are defined before the if statement. if (len(Item.objects.filter(owner=request.session['id'])) > 0): for x in Item.objects.filter(owner=request.session['id']): if (x.item == forageitem): x.amount = x.amount + 1 x.save() messages.success(request, "You found a " + forageitem +".") return redirect("/dashboard") else: continue The function passes through the if statement just fine, but if the item in question is not found, it will not create a new object in the Item class, instead it will give me an error. For some reason, I am getting a ValueError at this part of my code: else: Item.objects.create(item=forageitem, owner=User.objects.get(id = request.session['id']), description=item[forageitem], amount=1) messages.success(request, "You found a " + forageitem +".") return redirect("/dashboard") I am almost certain I didn't change anything here, it was working before. Ideas, anyone? Please help. -

Why is nothing being saved when trying to update objects with objects.all() and a dedicated model method?
I am writing an API to help me maintain my django db when needed. One function of my API is to update a specific field for all concerned objects thanks to a dedicated method of my model. The issue I have been facing with is the following: nothing is being saved when trying to do so! This specific model is using geoDjango. Here below is an example of my model: models.py class Location(geoModels.Model): coord_field = geoModels.PointField(blank=True, null=True) def update_coord_field(self): # function does some useful stuff self.coord_field = newValue Now here is what I am trying to do from a script being executed through python manage.py shell: script.py from MyApp import models as MyAppModels def update_all_coord_field(): for location in MyAppModels.Location.objects.all(): print(location.coord_field) # display old value location.update_coord_field() location.save() print(location.coord_field) # display new value: nice! But when trying to execute my script again (or simply just trying to use my new valued attribute), I can only observe that nothing was saved to the db. Would you have any idea why this is not working? To me, doing this is the same as doing MyAppModels.Location.objects.update(coord_field=newValue) for all concerned objects... but even doing that is not working.

Error sending a file using Django - file turns out empty

Passing Url params from one page to another
So I have a filter form on a page that show paginated results. Currently when you apply the filter settings using a get request everything works but when you try to switch pages it resets. I have thought of passing a url from one page to another using a script like the one below. This copies the url but does not actually change the page, just copies the string. You can see in the urls below that the url does change page but the actual webpage stay on the first page regardless of the url. I am using Django and Django filters. Maybe a there is a better jQuery solution, Any suggestions? script document.querySelectorAll('.fqs') .forEach((el) => el.attributes.href.value += window.location.search); Url Without script: /relations/?createdBy=&occursIn=&createdAfter=&createdBefore=&terminal_nodes=&project=1 With Script: /relations/?page=2?createdBy=&occursIn=&createdAfter=&createdBefore=&terminal_nodes=&project=1 Next Page Link <a class="fqs" href="?page={{ relations.next_page_number }}">Next &raquo;</a> -

Creating auth token for non user object django rest framework
I am looking to generate a django authtoken for a non user object. previously I had easily generated auth tokens for user objects like this email = request.data.get('email') user = User.objects.get(email=email) Token.objects.create(user=user) but if I am trying this for non user object it is not getting generated. device_id = request.data.get('device_id') tablet = Table.objects.get(device_id=device_id) Token.objects.create(user=tablet) Here Table is simple model holding various device_ids. I just want to generate an auth token for each tablet like we do for each user.
