Mocking models used in a Django view with arguments
For the life of me I cannot figure this out and I'm having trouble finding information on it. I have a Django view which accepts an argument which is a primary key (e.g: URL/problem/12) and loads a page with information from the argument's model. I want to mock models used by my view for testing but I cannot figure it out, this is what I've tried: @patch('apps.problem.models.Problem',) def test_search_response(self, problem, chgbk, dispute): problem(problem_id=854, vendor_num=100, chgbk=122) request = self.factory.get(reverse('dispute_landing:search')) request.user = self.user request.usertype = self.usertype response = search(request, problem_num=12) self.assertTemplateUsed('individual_chargeback_view.html') However - I can never get the test to actually find the problem number, it's as if the model does not exist. -

How to get the request object in Django?
I want to access the request.user and request.session deep in my Django project. As I didnt want to pass the request object (from the view) in tons of methods on the way, I created a thread local middleware to accomplish this. But later I came to know that this is not a fail proof/safe method (Why is using thread locals in Django bad? and https://www.pythonanywhere.com/forums/topic/710/). It is mentioned there that one thread can process multiple API requests. (How is this even possible?-not my main issue right now) Anyways, I have to accomplish this in a new way. Help appreciated. Thank you in advance! -
Django + Active Directory Using Current Data
I have a Django project with MS SQL Server as the backend. I also have Active Directory information (i.e. username, first name, last name and email) in a table that is updated daily and not currently related to the Django project. Is there a way to just write that information to the Django auth_user table and use that to provide Active Directory "integration"? I understand I could use a third-party package to actually integrate Active Directory, but I'm wondering if it's possible to take advantage of the existing data stream. The part I don't know is how Active Directory passwords would work if I was just writing users (without passwords) to the auth_user table. Update: The third-party package I would use says to map these fields: LDAP_AUTH_USER_FIELDS = { "username": "uid", "first_name": "givenName", "last_name": "sn", "email": "mail", } I currently have all those fields in my unrelated table. However, the package also says "When a user attempts to authenticate, a connection is made to the LDAP server, and the application attempts to bind using the provided username and password.". My intuition tells me that writing from the unrelated table would mimic syncing Active Directory users to the auth_user table, but … -

Passing Django Queryset in Views to Template
I have a Django Views which has some logic for passing the correct category to the template. class ProductListView(ListView): model = models.Product template_name = "catalogue/catalogue.html" def get_queryset(self): category = self.kwargs.get("category") if category: queryset = Product.objects.filter(category__iexact=category) else: queryset = Product.objects.all() return queryset I can't work out how to pass this to the template, my template code is as below: {% for product in products %} <tr> <td><h5>{{ product.name }}</h5> <p>Cooked with chicken and mutton cumin spices</p></td> <td><p><strong>£ {{ product.price }}</strong></p></td> <td class="options"><a href="#0"><i class="icon_plus_alt2"></i></a></td> </tr> {% endfor %} I am pretty sure my template syntax is wrong, but how do I pass the particular category to the template?

With Django, why do I get 404 errors on static resources during login?
I know very little about Django. I am taking over a project that was developed by someone else. I was asked to implement a new design. Now suddenly I get an error when I try to log in. I get a broken page, which I'm not supposed to see, as it is should simply redirect me to my the user's profile page. Instead, this happens: [31/Jan/2018 13:28:47] "POST /accounts/login/ HTTP/1.1" 200 2829 [31/Jan/2018 13:28:48] "GET /static/core/bundles/main.css HTTP/1.1" 404 1787 [31/Jan/2018 13:28:48] "GET /static/core/img/sugar-notagline-23may.jpg HTTP/1.1" 404 1826 [31/Jan/2018 13:28:48] "GET /static/core/img/tools.png HTTP/1.1" 404 1778 [31/Jan/2018 13:28:48] "GET /static/core/img/library.png HTTP/1.1" 404 1784 [31/Jan/2018 13:28:48] "GET /static/core/img/filter1.png HTTP/1.1" 404 1784 [31/Jan/2018 13:28:48] "GET /static/core/img/settings.png HTTP/1.1" 404 1787 There is the main.css file here: ./sugarlab/core/static/core/bundles/css/main.css I don't get why that is a 404, since on other pages it seems to be included fine. The images don't exist, but that shouldn't matter, because this page is not supposed to be shown to the user. Assuming I've broken some redirect mechanism, what should I be looking for? How would this redirect normally be handled? -
AngularJS $http request fails with custom headers

ModuleNotFoundError: No module named 'googlemaps'
