Algolia ranking edge cases
I am new to Algolia and Django so any help with the following task would be much appreciated. I am trying to re-rank the search results on the UI such that certain edge cases don't cause issues anymore. The problem was that initially there was only one searchable attribute that was used but we actually want that one to be split into 2. I did that so I split the initial attribute into 2 attributes, call them attribute_1 and attribute_2 and also passed them in the settings of the index.py file as follows: "searchableAttributes": [ "attribute_1", "attribute_2" ] From the documentation I understand that the order in which the attributes are added in the above lists prioritizes the search so the search engine will first look for matches in attribute_1 and then in attribute_2. This solved the issue for one of the edge cases but there is still one edge case that is not solved. I will explain the issue with this edge case below in more detail. Call the 2 examples that I want to be ranked for the remaining edge case E1 and E2. The search keyword, call it some_text, matches perfectly attribute_1 of E1 but it is … -
Perform action on saving inline django model
I have two models, one CommentModel displayed as an inline to the MainModel in the admin. models.py: class MainModel(models.Model): customer = models.OneToOneField(Customer, on_delete=models.CASCADE) class CommentModel(models.Model): main = models.ForeignKey(MainModel, on_delete=models.CASCADE, default=None) comment_german = CharField(blank=True, default='', null=True) comment_english = CharField(blank=True, default='', null=True) admin.py: class MainModelAdmin(SimpleHistoryAdmin): model = MainModel inlines = [CommentModelInline] class CommentModelInline(admin.StackedInline): model = CommentModel fields = ['comment_german', 'comment_english'] Suppose I want to automatically translate what the user writes in the comment_german field and save it to the comment_english field when the MainModel is saved. I tried overriding the save method. I successfully did it for another model which is not an inline. But this does not work for inlines. I need something like this: def save(self, *args, **kwargs): super().save(*args, **kwargs) for comment in CommentModel.objects.filter(main=self): if comment.comment_german != '' and comment.comment_english == '': comment.comment_english = comment.comment_german.translate_to_english() There must be a way to do this, maybe with a formset, but I can't wrap my head around it. -
Django Clear Sessions and Flags every 20 mins
I am working on a Django Website in which whenever a user logs in it creates a session and in Models active is set to true (is_active=true) when users logout the sessions clear and is_active=false for the user But the problem is when a User closes the tab/ browser instead of logging out user is still said to be active . How to make a function which will logout all active users after 15 mins of their login? Models.py class Employee(models.Model): emp_id = models.CharField(primary_key=True,max_length=50) name = models.CharField(max_length=50) gender = models.CharField(max_length=50,default="None") email = models.EmailField(max_length=50) password = models.CharField(max_length=50,help_text="Minimum of 8 Characters") dept = models.CharField(max_length=50) phone = models.CharField(max_length=20) last_login=models.DateTimeField(auto_now_add=True, blank=True) is_active=models.BooleanField(default=False) authcode=models.CharField(max_length=25) Views.py def home(request): loginUser= request.session['username'] if loginUser == '': return redirect('log') name= request.session['name'] return render(request,'home.html') def logot(request): loginUser=request.session['username'] Employee.objects.filter(emp_id=loginUser).update(is_active=False) request.session['name']=''; request.session['username']=''; return redirect('welcome') # def scheduled_logout # Logout all user's after 15 mins of last_login Thanks in advance -
Django migration : deleted column, now django says it doesn't exist
I want to get rid of a field of one of my models which has quite a few objects. This field was barely used so I removed every call to it from my code and did the migration. This migration couldn't be simpler, and it didn't cause any issue on my dev server. So I did the same on my running server. # Generated by Django 2.2.19 on 2021-06-22 12:29 from django.db import migrations class Migration(migrations.Migration): dependencies = [ ('my_app', '0010_auto_20210611_0751'), ] operations = [ migrations.RemoveField( model_name='permission', name='type', ), ] But when I try to access objects that relate to this model in my admin view, it throws psycopg2.errors.UndefinedColumn: column my_app_permission.type does not exist LINE 1: SELECT "my_app_permission"."id", "my_app_permission"... I don't understand why it looks for type when there is no reference to it in my code. I ran Django's manage.py shell and requested my Permission objects. I got them without any issue. I tried to access their type field, but it didn't exist as expected since the migration. Which means in the database the column "type" has been deleted as I asked. The error message doesn't give any insight as to what causes my error, it says the error … -

Ionic& Angular: Ran into status 0 Unknown Error, what can I do when I cannot reproduce the same error?
I have helped to develop a hybrid check-in mobile app using Angular & Ionic. One of the clients informed that the following error occurs. Http failure response for https://url.com/api/: 0 Unknown Error. But it seems I cannot reproduce the same error, as it happens randomly after some days. I have gone and added a retry feature to my subscription, as well as being able to send me an email if the error happens again; since I have to know what is causing the issue. The snippet code is below, but the same issue is happening on different endpoints: this.sharedService.uploadImageToVisionAPI(image.dataUrl) .pipe(retryWhen(error => { return error.pipe( // we use mergeMap instead of switchMap to have all request finished before they are cancelled mergeMap((error, i) => { const retryAttempt = i + 1; // if maximum number of retries have been met // or response is a status code we don't wish to retry, throw error const scalingDuration = 500; if (retryAttempt > 9) { return throwError(error); } console.log( `Attempt ${retryAttempt}: retrying in ${retryAttempt * scalingDuration}ms` ); return timer(retryAttempt * scalingDuration); }), finalize(() => console.log('We are done!')) )})) .subscribe(confidence_percentage => { let confidence = confidence_percentage['percentage'] }) Have you ran into a similar error, … -
How to use django-select2 widgets in django admin site?
In my django app I have modified the User entity to include a worker field (OneToOneField). But from the django admin site that field yiels so many result , so it is difficult for the logged user to select a worker. Is there any way to use the select2 (ModelSelect2Widget) widgets from the django admin site? For any regular form I have define the widgets in the following way: from django_select2.forms import ModelSelect2Widget class ProcessForm(forms.ModelForm): class Meta: model = ProcessModel exclude = ('id',) widgets = { 'name':forms.TextInput(attrs={'class': 'form-control'}), 'code':forms.TextInput(attrs={'class': 'form-control'}), 'description':forms.Textarea(attrs={'class': 'form-control'}), 'geom': LeafletWidget(), 'product': ModelSelect2Widget(model=ProductModel, queryset=ProductModel.objects.filter(), search_fields=['name__icontains'], attrs={'style': 'width: 100%;'}), } Is there any way to use the ModelSelect2Widget for the worker field in the admin site form? Here is my code: class User(AbstractUser): worker = models.OneToOneField(WorkerModel, on_delete=models.CASCADE, related_name="user", verbose_name=_("Trabajador"), null=True, blank=True) class Meta: default_permissions = () verbose_name="Usuario" verbose_name_plural="Usuarios" permissions = ( ("secretario", "Secretario(a)"), ("director", "Director"), ) from django.contrib.auth.admin import UserAdmin class UserAdminInherited(UserAdmin): fieldsets = ( (None, {'fields': ('username', 'password')}), (_('Personal info'), {'fields': ('first_name', 'last_name', 'email')}), (_('Worker info'), {'fields': ('worker',)}), (_('Permissions'), { 'fields': ('is_active', 'is_staff', 'is_superuser', 'groups', 'user_permissions'), }), (_('Important dates'), {'fields': ('last_login', 'date_joined')}), ) admin.site.register(User, UserAdminInherited) -
not found(deploying via digitaloccean, nginx, ubuntu, Gunicorn )
I tried to deploy Django via digitaloccean, nginx, ubuntu, and Gunicorn. I followed the tutorial that digitaloccean provided. Everything was fine before the step of binding it with Gunicorn. I was able to use the run "manage.py runserver 0.0.0.0:8000"and was able to see the website on port 8000 of the IP address; however when I tried to run gunicorn --bind 0.0.0.0:8000 myproject.wsgioutput,and tried to connect to the IP address again, the 404 not found error occurred.output I also tried every port of the IP address but none of them worked. This is the output of systemctl status gunicorn.service output. And this is the output of sudo journalctl -u gunicornoutput. I have the following questions: What might possibly cause this error? Does being able to run it on local server means that the error is not caused by the source code? What can I try to fix this issue? Thank you !!! -

ProgrammingError after reverting migration after AttributeError
I did the migration after adding SourceBook and SourceBooksOrderable and that worked. Then I managed to add two snippets in wagtail admin.

Django HttpOnly cookie doesn't protect but user can stop it if a malicious code didn't take an action yet. Am i right?
So in my understanding there are two ways of an XSS attack. Attacker user sends malicious Javascript code to backend and when another user opens it will have access to that users data. It is generally prevented with framework itself but you can also encode the data before sending to the backend and filter them before storing them into database in the backend side. When you open want to access it in the client side you decode it again. Browser extensions. Browser extensions have a all the access of client side. They cannot access HttpOnly cookies. But they can still send requests to backend, post something etc. If you use HttpOnly cookie once a user disables extension it will not have the control anymore. Am i right or is there another way of making an XSS attack? -

Django formsets in formsets
I am creating a quiz app. A quiz has one or more questions, each question has one or more images. I've already used django-dynamic-formsets to allow the user to create/delete multiple questions. However, I am struggling to find a method that allows the user to upload images for specific questions, and then for Django to recognise which images 'belong' to each question. Because a question could have multiple images (up to some unknown amount) I cannot just hard code multiple fields in my question model. My current code has a model for questions, and models for 'choices' which has a foreign key to a question model. -

nginx + django + haystack = Server Error (500)
I've cobbled together a small blog application in Django using Haystack with Whoosh backend for search. It runs nicely in development server (on the laptop) but search fails when site runs in nginx on a server (rpi). I can access search page but any search results in Server Error (500), no additional info available from either nginx or django logs. I had RealtimeSignalProcessor on but turned it off - no change. Any pointer on how to attempt to debug this would be great.
