What do these 3 lines do exactly in django function views?
I am trying to create a simple blog site and in the tutorial, the teacher wrote this function view. I am unable to understand what do these lines do exactly. I have them as comments in the code This is the Function View @login_required def add_comment_to_post(request,pk): post = get_object_or_404(Post,pk=pk) if request.method == "POST": #Below is line no.1 form = CommentForm(request.POST) if form.is_valid(): #Below are lines no.2 & 3 comment = form.save(commit=False) comment.post = post comment.save() return redirect('post_detail',pk=post.pk) else: form = CommentForm() return render(request,'blog/comment_form.html',{'form':form}) This is my Models.py file from datetime import time from django.db import models from django.utils import timezone from django.urls import reverse # Create your models here. class Post(models.Model): author = models.ForeignKey('auth.User',on_delete=models.CASCADE) title = models.CharField(max_length=200) text = models.TextField() create_date = models.DateTimeField(default=timezone.now()) published_date = models.DateTimeField(blank=True,null=True) def publish(self): self.published_date = timezone.now() self.save() def approved_comments(self): return self.comments.filter(approved_comment=True) def get_absolute_url(self): return reverse("post_detail", kwargs={"pk": self.pk}) def __str__(self): return self.title class Comment(models.Model): post = models.ForeignKey('blog.Post',related_name='comments',on_delete=models.CASCADE) author = models.CharField(max_length=200) text = models.TextField() create_date = models.DateTimeField(default=timezone.now()) approved_comment = models.BooleanField(default=False) def approve(self): self.approved_comment = True self.save() def get_absolute_url(self): return reverse("post_list", kwargs={"pk": self.pk}) def __str__(self): return self.text I have two forms in my forms.py file namely PostForm and CommentForm. -

Apache + mod_wsgi + django: send a default response for a backlogged request
I am running a web server using Apache 2.4, mod_wsgi, and Django. The server overloads occasionally due to high traffic. I want to setup the server such that it responds with a pre-determined default response to backlogged requests (i.e., requests that have been waiting in the queue over a certain timeout). What is the best way to do this? Additionally, I want to the keep the connection alive after sending the default response. Any help is much appreciated. -

Concurrency issue when processing webhooks
Our application creates/updates database entries based on an external service's webhooks. The webhook sends the external id of the object so that we can fetch more data for processing. The processing of a webhook with roundtrips to get more data is 400-1200ms. Sometimes, multiple hooks for the same object ID are sent within microseconds of each other. Here are timestamps of the most recent occurrence: 2020-11-21 12:42:45.812317+00:00 2020-11-21 20:03:36.881120+00:00 <- 2020-11-21 20:03:36.881119+00:00 <- There can also be other objects sent for processing around this time as well. The issue is that concurrent processing of the two hooks highlighted above will create two new database entries for the same single object. Q: What would be the best way to prevent concurrent processing of the two highlighted entries? What I've Tried: Currently, at the start of an incoming hook, I create a database entry in a Changes table which stores the object ID. Right before processing, the Changes table is checked for entries that were created for this ID within the last 10 seconds; if one is found, it quits to let the other process do the work. In the case above, there were two database entries created, and because they were … -
Could UUID be used as a tracking number that user will use?
I am developing a Reporting system where a user can report another user for a variety of issues. To display the report to the user, I am thinking of doing something like localhost:8000/reports/(UUID from model). Essentially use it as a tracking number that I will be displaying to the user so that they can track their reports. Are there any reasons that I shouldn't do it this way (security? something simpler?) Thanks a lot in advance! -
Django Formset template
Probably easy stuff, I want to display each field from a formset using 2 model, but I can only display the "facture" model which is the parent.

Understanding the def clean(self) method inside custom login form class
Django Version = 2.2.2. Does it not make sense to take out the def clean(self) method from class LoginForm(form.ModelForm) class LoginForm(forms.ModelForm): password = forms.CharField(label='Password', widget=forms.PasswordInput) class Meta: model = Account fields = ['email', 'password'] def clean(self): if self.is_valid(): email = self.cleaned_data['email'] password = self.cleaned_data['password'] if not authenticate(email=email, password=password): raise forms.ValidationError('Invalid login') and put it inside the view function for login: def login_screen_view(request): context = {} if request.POST: form = LoginForm(request.POST) if form.is_valid(): email = request.POST['email'] password = request.POST['password'] user = authenticate(email=email, password=password) if user: login(request, user) return redirect('home') else: form = LoginForm() context['login_form'] = form return render(request, 'account/login.html', context) So that the above two blocks of code becomes now this: class LoginForm(forms.ModelForm): password = forms.CharField(label='Password', widget=forms.PasswordInput) class Meta: model = Account fields = ['email', 'password'] def login_screen_view(request): context = {} if request.POST: form = LoginForm(request.POST) if form.is_valid(): email = request.POST['email'] password = request.POST['password'] user = authenticate(email=email, password=password) if user: login(request, user) return redirect('home') else: raise forms.ValidationError('Invalid login') #i added this line else: form = LoginForm() context['login_form'] = form return render(request, 'account/login.html', context) The reason why I say all this is because in the def clean(self) method aren't you basically checking if the form is valid?

how to execute the api call inside a django view only if the template coresspanding to this view is called

fuzzy search in django without using Elasticsearch
I try to incorporate fuzzy serach function in a django project without using Elasticsearch. 1- I am using postgres, so I first tried levenshtein, but it did not work for my purpose. class Levenshtein(Func): template = "%(function)s(%(expressions)s, '%(search_term)s')" function = "levenshtein" def __init__(self, expression, search_term, **extras): super(Levenshtein, self).__init__( expression, search_term=search_term, **extras ) items = Product.objects.annotate(lev_dist=Levenshtein(F('sort_name'), searchterm)).filter( lev_dist__lte=2 ) Search "glyoxl" did not pick up "4-Methylphenylglyoxal hydrate", because levenshtein considered "Methylphenylglyoxal" as a word and compared with my searchterm "glyoxl". 2. python package, fuzzywuzzy seems can solve my problem, but I was not able to incorporate it into query function. ratio= fuzz.partial_ratio('glyoxl', '4-Methylphenylglyoxal hydrate') # ratio = 83 I tried to use fuzz.partial_ratio function in annotate, but it did not work. items = Product.objects.annotate(ratio=fuzz.partial_ratio(searchterm, 'full_name')).filter( ratio__gte=75 ) Here is the error message: QuerySet.annotate() received non-expression(s): 12. According to this stackoverflow post (1), annotate does not take regular python functions. The post also mentioned that from Django 2.1, one can subclass Func to generate a custom function. But it seems that Func can only take database functions such as levenshtein. Any way to solve this problem? thanks! -

Django render list of json data via ajax
I want to render a data frame to the front-end so that I can create a table on my html page.

Is there a way to run multiple concurrent Django apps (different settings, same code) in one process?
Basically this would be a situation where I'd want to run the same Django codebase, but use different settings for different incoming domain. For example, foo.bar might use the settings/foo_bar.py settings file, with a different database, etc. I'd like to have one process that, at runtime, "spins up" instances. Eg def find_django_app(wsgi_request): settings_file = ... django.use_settings(settings_file) # Does this exist? django.setup(set_prefix=False) return WSGIHandler() Is anything like that possible?
