Why to use the extra slash (/) at the end of the Django urls?
I'm trying to create a REST API using Django. I'm currently implementing the urls.py file. In a lot of different examples, I saw that they add / at the end of the url. For example: urlpatterns = [ path('login/', obtain_auth_token, name='api_token_auth'), ] I'm trying to figure way. Surely for login POST request which returns a token (given username and password), you want to access <domain>/api/login and not <domain>/api/login/. Currently I solved it with: urlpatterns = [ re_path(r'login$', obtain_auth_token, name='api_token_auth'), ] Or: urlpatterns = [ path('login', obtain_auth_token, name='api_token_auth'), ] But what is the convention? Why a lot of different examples add the extra / at the end? When do you want to add it? -
Django Multi-table inheritance - get parent object
How can I get the parent object from the child object in Multi-table inheritance? class Property(Model): .... class Meta: abstract = False #!!! class Flat(Property): .... flat = Flat.objects.first() flat.property >>> AttributeError: 'Flat' object has no attribute 'property There is a flat.property_ptr_id which I guess I could use but I'm curious if there is a more elegant/built-in way to do that. Btw. I know I can access all the fields from the child object. I'm working on methods like create_child, convert_child_type. -
How to create a pagination for a dataframe?
I want to create a pagination system for my dataframe. I always create pagination with my queries but It doesn't work in dataframe. I cannot display on my template. This is my views.py def get_context_data(self, **kwargs): ... df = pd.DataFrame(list(Case.objects.all().values(...))) query = df.assign(cnt=1).groupby([...)['cnt'].sum().reset_index() paginator = Paginator(query, 10) page_number = self.request.GET.get('page') if page_number == None: page_number = 1 page_obj = paginator.page(int(page_number)) print(page_obj) ----> <Page 1 of 33> context['query'] = query return context And this is my template <table class="table table-bordered" > <tbody> {% for index, row in query.iterrows %} <tr> {% for cell in row %} <td> {{cell}} </td> {% endfor %} </tr> {% endfor %} </table> Table shows nothing. How can I solve that? -
Django. How to create model instance in test db using objects fabric?
I want to make my unit tests setUp function clear from repeating tons of model creation lines like 1) create user 2) now create employee with fk to this user and etc. In order to do that I've made a simple factory of dummy objects but I might've done some mistakes or just misunderstood something. Here's a piece of factory (dummy_data is just a bunch of dicts): from abc import ABC from users.models import User from employees.models import Employee from .dummy_data import( user_data, employee_data, ) class DummyObjectFactory(ABC): """Fabric representing dummy test objects""" def get_dummy_object(self): """Return dummy object""" class DummyUser(DummyObjectFactory): def get_dummy_object(self) -> User: return User.objects.create_user(**user_data) class DummyEmployee(DummyObjectFactory): def get_dummy_object(self) -> Employee: user = DummyUser().get_dummy_object() return Employee.objects.create(**employee_data, user=user) Then I make a dot notaion dictionary of all kinds of fabrics for easy calling them buy dummy_factory.Name . My intetion was that I call fabric with the desired model name and it creates it's instance. The problem is: when I call it in some test's setUp method like so test_user = dummy_factory.User it creates object in actual database but I want it to be in test database. Yes, I've searched for the solution and found Factory boy and Faker libraries, but I … -

HTML: show different sized tables on the same page depending on the user's choice
Is it possible to implement two different sized tables where only one would be displayed on the page depending on the user's choice? E.g.: user chooses data table which has the following columns: country, price, date, so 3 columns would be displayed. Then the user chooses the users table with columns: name, email, so now 2 columns would be displayed. -

How can I change the database time-out period in django?
I have django script which fetch the data from model. try: myuser = MyUser.objects.get(id=user_id) except Exception as e: print(e) # do next process Then, what I want to do is ,,, When database is stopped or not reached, I want to catch and do next process.

Django - How to include form field logic in modelForm and not in a Createview, so that form can be unittested without also testing the view?
I have a Campaign Model, and a CampaignCreateForm which is a ModelForm. The Campaign model has a contact_list field of type JSONField. When a user is creating a campaign using the CampaignCreateFormthey upload a CSV file which is processed to create the JSON data for thecontact_list` field. What is the best way to approach this so that I can test the form separately from the view? I've built this using a CampaignCreateView which inherits from CreateView, and included the logic to parse the CSV file and create the JSON data in the views form_valid method, but this makes unit-testing the form (and any form field validation) impossible. I want to test the functions included in the forms clean method. With my current approach the view and form must be tested together, and that feels wrong. How can I create the form such that all the logic for the form (processing the CSV file to create the JSON data and discarding the uploaded file) is handled in the form only? My current CreateView and ModelForm are below: View: class CampaignCreateView(LoginRequiredMixin, CreateView): model = Campaign form_class = CampaignCreateForm # required if you want to use a custom model form, requires `model` also … -

Huge discrepancy between access.log, Google Analytics and Mapbox Statistics
I have a website made in django and served using gunicorn in which a single Mapbox map is loaded on the home page using mapbox-gl.js. Users can then navigate the map and change styles at will. The map is initialized and loaded only once and only in the home page. The service is billed on a "map load" basis. The Mapbox pricing page says A map load occurs whenever a Map object is initialized, offering users unlimited interactivity with your web map. I would have expected to see a count, if not exactly identical, at least comparable between the data recorded by Mapbox billing, the accesses to the home page recorded by Google Analytics and the hits on the home page recorded on the server access.log. Instead, the Mapbox count is in average about 25 times higher than Analytics and the access.log, which have similar numbers. As an example, here are the numbers for yesterday: Analytics: home page was loaded 890 times access.log: 1261 requests for the home page Mapbox: 23331 map loads I am using URL restriction from the Mapbox control panel, but I guess the enforcement is not that strict, since they strongly suggest to also rotate the … -

Django admin Resource Policy COEP ERR_BLOCKED_BY_RESPONSE
The static files of my Django admin site are on a S3 bucket (DigitalOcean Spaces actually) and in the Console I get a ERR_BLOCKED_BY_RESPONSE.NotSameOriginAfterDefaultedToSameOriginByCoep 200 In the network panel all the static files are considered 3rd party and blocked for this reason (not same origin) The response to any one of these files contains a not set cross-origin-resource-policy error which says: To use this resource from a different origin, the server needs to specify a cross-origin resource policy in the response headers. What I tried : Following the error message, I tried to set a response header on the ressources, something like Cross-Origin-Resource-Policy: cross-origin. But in a DigitalOcean Spaces I cannot set headers other than Content-Type, Cache-Control, Content-Encoding, Content-Disposition and custom x-amz-meta- headers. I tried to extend the Django admin/base.html template, duplicate a few link tags and manually set a crossorigin attribute to them. This way the resources are queried twice, one query is blocked as before and the other one is working. The only difference in the headers is that the Origin is set. Is there a way to tell Django to add a crossorigin attribute to all link and script and img tags of the Django admin templates …
