Different models order in main.django_content_type table during unittesting
I'm using django 3.1 with SQLite DB. I'm using my django project as API, so django rest framework is installed as well. During my unittest (with pycharm) I've observed that in table main.django_content_type some models in my dev DB and test DB are ordered differently and have different IDs. For example defaultcategory and customcategory: dev DB: admin logentry auth permission auth group contenttypes contenttype sessions session core customuser core historicalcustomuser authtoken token authtoken historicaltoken finances fixtransaction finances historicaldefaultcategory finances historicaltransfer finances historicaltransaction finances transaction finances fixtransfer finances historicalfixtransfer finances historicalcostaccount finances historicalfixtransaction finances transfer finances costaccount finances historicalcustomcategory finances defaultcategory finances customcategory test DB: admin | log entry auth | permission auth | group contenttypes | content type sessions | session core | custom user core | historical custom user finances | cost account finances | transfer finances | transaction finances | historical transfer finances | historical transaction finances | historical fix transfer finances | historical fix transaction finances | historical default category finances | historical custom category finances | historical cost account finances | fix transfer finances | fix transaction finances | default category finances | custom category authtoken | Token authtoken | historical Token Is there any way … -
Django- Query Multiple models with many to many and one to one relationships
Reposted from an earlier question - but made simpler: 3 Models: Actor(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4) type = models.Charfield(max_length=20) Organisation(models.Model): id = id = models.UUIDField(primary_key=True, default=uuid.uuid4) name = models.Charfield(max_length=20) actor = models.OneToOneField(Actor, on_delete=Models.CASCADE) parent_organisation = models.ForeignKey(Actor, on_delete=models.CASCADE) CustomUser(AbstractBaseUser,PermissionsMixin): id = models.UUIDField(primary_key=True, default=uuid.uuid4) name = models.Charfield(max_length=20) member_of = models.ManyToManyField(Actor, on_delete=models.CASCADE) actor = actor = models.OneToOneField(Actor, on_delete=Models.CASCADE) Note: I have left out fields which are not important. In the Views.py - I wish to find all users within an organisation - Such that given an organisation id, I get the users for the whole organisation. I wish to find all the users with a department - Such that given an organisation id, I get the users for the department (NB: departments are linked on the same organisation model but by the parent -FK) I have tried many different combinations over the last 3 days including: Chaining by : current_organisation = Actor.objects.get_actor(request.session['organisation']).first() This works and I get the Organisation that a user belongs to; The next step: organisation_departments = Actor.objects.filter(parent__actor_id__in =current_organisation) gives me an error of 'Actor' object is not iterable I have looked through the Docs and a similar example here. am I right in suggesting that there should be method using … -

Django: window.localstorage to store a CSS animation
I'm trying to make a facebook inspired ajax like button with Jquery and Django. The AJAX call is working. The button has a counter, the users' names who have liked the post along with a CSS animation just like facebook's (where on clicking the button, it turns blue and when clicking it again, the button goes back to normal). The problem is on reload, my CSS animation on the button is gone and I'm not able to update the counter and the user's name on the list while on an AJAX call (Althought they work on page reload, not the CSS animation though). For CSS animation I tried to use Javascript's localStorage method but it just toggles the CSS animation and doesn't store it locally. A little help would be appreciated. Here's my code: #Like-Button-Form(i is iterating through my post model object): <form id="like_form" method="get"> <!-- {% csrf_token %} --> <div class="like"> <button type="button" name="post_id" id="like{{ i.id }}" data-catid="{{ i.id }}" class="like_ajax_btn" value="{{ i.id }}"> <i class="fad fa-heart"></i> Like </button> {% if i.like %} <div class="show_likes"> {{ i.total_likes }} Like{{ i.total_likes|pluralize }} <div class="username_liked"> {% for p in i.like.all %} <div><a class="username_likes_post" href="{% url 'userprofile' p.id %}">{{ p.username }}</a></div> {% … -
DJANGO - USER'S NOTIFICATION
I'm working on a django project. It manages designers projects. Each project has a worker (who is working on the project) and a responsible (who assigns the project to a worker). The worker can modify some attributes of the project through an Update Form (and one of the project's attributes is 'complete', that is a boolean). When the worker goes to the update form and checks the 'complete' checkbox, I'd like to implement the feature of sending a notification to the projects' responsable to let him know that the project has been finished. So I'd like to sent the notification not every time that the worker modifies the projects, but just when he checks the 'complete' checkbox. How should I do that? Each project has an image field for the final result of the project, and I'd like to know if it is possible to attach it to the notification that it is sent when the workers marks that the project has been completed. Also, as well as the notification, I'd like to send the responsible an email always with the image attached. To do that do I need to use celery or there is a simpler way that doesn't … -

Django + Mongodb : Subsetting data in the backend/frontend(template)
My django app pulls raw facebook data from a mongodb database (via djongo/pymongo) and run its through a series of internal data pipelines. At my dashboard.html page, I'm displaying some metrics(posts count, likes count etc..) for the past 7days. Everything works fine up to this point. Now I would like to let the user select from a dropdown menu list whether "past 7 days" or "past 14 days" should be displayed. Obs: It seems that I can't simply use QuerySet because the data being displayed needs to be processed in different pipelienes in the backend before rendering. Obs2: As of now I have some duplicated code in my view in order to get "7 days data" and "14 days data". I would like to simplify that. Obs3: Perhaps Ajax could be a way to go (avoid caching delay/page refresh) but I can't figure out a way to implement that. Thank you in advance!! my views.py: @login_required def dashboard(request): # Mongodb connection this_db = DatabaseFb( 'xxxxMyMongodbConnectionxxx', 'mydbname') collection_posts = this_db.collections('fb_posts') collection_comments = this_db.collections('fb_comments') # ####### Past 7 days FB data ################# this_puller_7d = DataPullerFB(collection_posts, collection_comments, past7days) posts_7d = this_puller_7d.posts_data_puller() comments_7d = this_puller_7d.comments_data_puller() this_dataprep_posts = DataPrepPosts(posts_7d) df_posts_7d = this_dataprep_posts.to_timeseries() this_dataprep_comments = DataPrepComments(comments_7d) … -

The error I get after I run the server is: Reverse for 'random_book' with arguments '('',)' not found. 1 pattern(s) tried: ['book/(?P[-a-zA-Z0-9_]+)$'] It highlights this with red from template: {% url 'random_book' random_item.slug %} Models: class Books(models.Model): title=models.CharField(max_length=200) author=models.CharField(max_length=150) description=models.TextField() cover=models.ImageField(upload_to='images/', blank=True) slug=models.SlugField(max_length=100, blank=True, unique=True) genre=models.ManyToManyField(Genres) def save(self, *args, **kwargs): self.slug= slugify(self.title) super().save(*args, **kwargs) def __str__(self): return self.title def get_absolute_url(self): kwargs=self.slug return reverse('random_book', kwargs=kwargs) Views: def random_book(request, slug): cartile=Books.objects.all() random_item=random.choice(cartile) return render(request, 'carti/book.html', context={"random_item": random_item}) Urls: path('book/<slug:slug>', views.random_book, name="random_book"), Template: <a href="{% url 'random_book' random_item.slug %}">{{ random_item.title }}</a> Hope you guys can help me. -
Scipy, Scispacy, Django, Docker Issue
Having issues with scipy and numpy. This code, part of a Django app, runs perfectly when run on my windows 10 system: try: # sparse_load is a scipy.sparse.csr_matrix sparse_load = scipy.sparse.load_npz(cache) logger.info('Got sparse_load') concept_alias_tfidfs = sparse_load.astype(numpy.float32) except: logger.exception('Something went wrong!' ) # code continues here ... It also runs perfectly when running inside a docker container deployed on a Linux server. The issue is that the type conversion (sparse_load.astype(numpy.float32)) crashes my app when running in a docker container deployed on Docker Desktop running on Windows 10. The strange thing is that logger.exception is never executed! I've tried other type conversions with the same result and also tried removing the astype altogether which resulted in another crash further down in the code (again w/o hitting the exception handler placed around that piece of code. Thoughts?
