Django NoReverseMatch / Reverse for 'your-url' with arguments '('',) , When Used DeleteView

Django: How to hide Sites framework from Django Admin while using django-allauth?
Background I have a django server that uses django-allauth for handling authentication logic. I want to unregister Sites framework from django-admin, in other words, I do not want to see the Sites section inside django-admin: What I tried Normally, I would do one of the two things: Unplug django.contrib.sites from INSTALLED_APPS in settings.py Unregister Sites model from within one of my admin.py files like so: admin.site.unregister(Sites) The problem I tried doing both options above.

How do I test that my Celery worker actually works in Django
(code at bottom) Context: I'm working on a Django project where I need to provide the user feedback on a task that takes 15-45 seconds. In comes Celery to the rescue! I can see that Celery is performing as expected when I celery -A tcommerce worker -l info & python manage.py runserver. Problem: I can't figure out how to run a celery worker in my tests. When I run python manage.py test, I get the following error: Traceback (most recent call last): File "/Users/pbrockman/coding/t1v/lib/python3.8/site-packages/django/test/utils.py", line 387, in inner return func(*args, **kwargs) File "/Users/pbrockman/coding/tcommerce/tcommerce/tests.py", line 58, in test_shared_celery_task self.assertEqual(result.get(), 6) File "/Users/pbrockman/coding/t1v/lib/python3.8/site-packages/celery/result.py", line 224, in get return self.backend.wait_for_pending( File "/Users/pbrockman/coding/t1v/lib/python3.8/site-packages/celery/backends/base.py", line 756, in wait_for_pending meta = self.wait_for( File "/Users/pbrockman/coding/t1v/lib/python3.8/site-packages/celery/backends/base.py", line 1087, in _is_disabled raise NotImplementedError(E_NO_BACKEND.strip()) NotImplementedError: No result backend is configured.

How to lazy paginate a bootstrap table with slow data
We have a scientific database with a number of fields that are Django "cached properties". These cached property fields are slow to retrieve. Rendering a table (decorated with bootstrap-table) with around a thousand results is annoying, but doable. However now that we're loading a lot more data into the database, rendering these tables ends up hitting the 90 second timeout. We have explored various options to speed things up, but most methods do not support cached properties, which is a non-starter. We're looking for a temporary solution short of taking the cached property speed issue (which is the root of the problem) head on. Our current idea was to paginate. However, it looks like it's impossible to do it without a major refactor in order to retain all of our current complex functionality. We would like to retain this bootstrap functionality: Column switching (show/hide columns) between page loads Column sorting such that it takes all data (on or off the current page) into account And we want to retain this complex Django functionality/implementation: Complex django templates that renders data on each row that spans multiple many-to-many table relationships using nested loops and custom tags that: Filtering of rows from related … -
How to detect faces with imutils?

The functions below within the view.py are to detect the employee face and capture 300 images of the logged in employee - Essentially the aim of this question is to resolve the face detection issue and the issue is specifically lying within face_aligned = fa.align(frame, gray_frame, face). views.py: def create_dataset(username): id = username if (os.path.exists('Recog_Data/Train_Data/{}/'.format(id)) == False): os.makedirs('Recog_Data/Train_Data/{}/'.format(id)) directory = 'Recog_Data/Train_Data/{}/'.format(id) # Detect face # Loading the HOG face detector and the shape predictpr for allignment print("[INFO] Loading the facial detector") detector = dlib.get_frontal_face_detector() predictor = dlib.shape_predictor('Recog_Data/shape_predictor_68_face_landmarks.dat') # Add path to the shape predictor ######CHANGE TO RELATIVE PATH LATER fa = FaceAligner(predictor, desiredFaceWidth=256) # capture images from the webcam and process and detect the face # Initialize the video stream print("[INFO] Initializing Video stream") vs = VideoStream(src=0).start() # time.sleep(2.0) ####CHECK###### # Our identifier # We will put the id here and we will store the id with a face, so that later we can identify whose face it is # Our dataset naming counter sampleNum = 0 # Capturing … -

How to I specify a generic form(ModelForm) for many Plugins in Django CMS?
I'm using Django 2.2 and Django CMS 3.7.1 I have a plugin defined like so: cms_plugins.py @plugin_pool.register_plugin class BackgroundImagePlugin(CMSPluginBase): """ Background Image """ name = "Background Image" model = models.GenericBackgroundImage form = admin.GenericPluginFormWithSettings render_template = "plugins/ofc/BackgroundImageFormBoxCta.html" I also have a generic ModelForm("GenericPluginFormWithSettings") that I'm creating. I'm passing this form to the plugin above. Here's that ModelForm Class: admin.py class GenericPluginFormWithSettings(ModelForm): class Meta: fields = '__all__' def __init__(self, *args, **kwargs): super(GenericPluginFormWithSettings, self).__init__(*args, **kwargs) raw_keys = list(self.fields.keys()) raw_keys.remove('top_margin') raw_keys.remove('bottom_margin') raw_keys.append('top_margin') raw_keys.append('bottom_margin') # raw_keys is in the right order here self.Meta.fields = raw_keys self.order_fields(raw_keys) The goal with this generic model form class is to always push two fields(top margin, and bottom margin) to the bottom of the order for whatever plugin they're used upon. This fails to order the fields in the order I need them to be in. The only thing that works is when I hard code the fields order like so: class GenericPluginFormWithSettings(ModelForm): class Meta: fields = ['image', 'header', 'top_margin', 'bottom_margin'] But obviously I can't hardcode them because I then I couldn't use this ModelForm Class with many different plugins with different other than those with image and header`. How can I implement a generic ModelForm that re-orders fields which … -
Django Token authentication problem accessing another account
I have made Account model, which is now custom user model in Django my app. Also, I have Token authentication, but I do not know how to refresh Token, and how frequently I have to change Token for user.. Also I have a problem, because a user after logging with token can access another account, by just changing id in url. How can I solve this problem. I thought about solution that I put id of user in Token, so when he access to some url I check if it is his id in url from Token. But I am not sure is this is good solution for Django, because I do not know how to add id in Token. Maybe Django has some cleverer solution. I am pretty new in Django, so... -

Accessing session variable based on variable in for loop django template
I have some products listed which can be in a cart, this cart is stored in a session variable dictionary for which the key is the product id and the value is some information about the quantity and stuff. I want to add the option to view (on the products page) how many of that product are in your cart. I know I can access session variables in a django template like this: {{ request.session.cart.2323.quantity }} Problem is, the key (2323 in this case) is a variable which depends on a for loop: {% for prod in products %} <p>{{ request.session.cart[prod.name].quantity }}</p> {% endfor %} But implementing it like that unfortunately is not possible. Is there any way in which this would be possible or would I have to change the way my cart works? -

models.py(shrunk to things that matter) class Messages(models.Model): sender = models.ForeignKey(Profile,related_name='sender',on_delete=models.CASCADE) receiver = models.ForeignKey(Profile,related_name='receiver',on_delete=models.CASCADE) forms.py class MessageForm(forms.ModelForm): subject = forms.CharField(max_length=100, required=False, help_text='Optional.') text = forms.CharField(max_length=4096, required=True, help_text='Required.') class Meta: model = Messages fields = ('receiver','subject','text',) I have a dropdown that shows all users that were made I would like to filter it based off some fields like is_active to showcase only users that are authenticated and more like this so I would like to override I think it's receiver queryset. def index(request): sendMessageForm = MessageForm() if is_staff: if is_active: else: What my current form displays. <select name="receiver" required="" id="id_receiver"> <option value="" selected="">---------</option> <option value="39">1</option> <option value="40">2</option> <option value="41">3</option> <option value="42">4</option> </select> -
Django migrate error: formisoformat argument must be string
I would really need help to understand this error I get in Django that suddenly appeared after I added a bunch of objects to a models.Model class. This error persists even when I comment out all the new objects that might have provoked the error. This error is a bunch of Tracebacks and at last it tells that there is a "TypeError: fromisoformat: argument must be str " in this line: return datetime.date.fromisoformat(value) in dateparse.py file. I've been looking for a solution for a few days now but can't seem to find any, I don't fully understand the functioning of django yet so it would be really great if anyone could tell me how to get through this. Thanks for your time. -
Django Ajax Reorder Not Updating the Field in Database
I'm building a list of students by each class in the grade. I have a folder full of profile pictures for students downloaded into my img folder and a column within my model that maps the details (name, class, age, etc.) to the image name. How do I tell my table to bring in the appropriate img for each student? Below I have my code working to use a single image as a constant (e.g. student1's picture shows up for everyone). list.html: <table class="table table-hover" id="table-ajax"> <thead class="thead-light"> <tr> {% comment %} <th></th> {% endcomment %} <th style="width: 50px; text-align: center;"></th> <th>{{ object_list|verbose_name:'field:name' }}</th> <th>{{ object_list|verbose_name:'field:hometown' }}</th> <th>{{ object_list|verbose_name:'field:birthday' }}</th> <th>{{ object_list|verbose_name:'field:race' }}</th> <th>{{ object_list|verbose_name:'field:rank' }}</th> <th style="width: 50px; text-align: center;">Pictures</th> <th style="width: 160px; text-align: center;">Actions</th> </tr> </thead> <tbody class="order" data-url="{% url 'cms:reorder' model_name %}"> {% include 'app/partials/pick_list_partial.html' %} </tbody> partial-list.html: {% for pick in object_list %} <tr id="{{ pick.pk }}"> <td><img src="{% static 'img/student1.jpg' %}" width="50" height="50"></td> <td><a href="{% url 'app:lead-list' pick.pk %}" title="Leads">{{ pick.name }}</a></td> <td>{{ pick.hometown }}</td> <td>{{ pick.birthday }}</td> <td>{{ pick.race }}</td> <td>{{ pick.rank }}</td> <td style="text-align: center;"> <a href="{% url 'app:file-list' pick.pk %}" class="btn btn-outline-success btn-sm border-0" title="Files"> <i class="fa fa-copy"></i></a></td> <td style="text-align: center;"> <a …
