Django db rounting for prefetch_related
The raw SQL of this Django query has two SQL sentences. Would it use the same database for these 2 sentences? Django query: brands = (Brand.objects.using('default') .prefetch_related('product_set') .select_related('vendor') .filter(id__in=(1000, 1100)) ) SQL: SELECT * FROM `vendors_brand` LEFT OUTER JOIN `vendors_vendor` ON (`vendors_brand`.`vendor_id` = `vendors_vendor`.`id`) WHERE `vendors_brand`.`id` IN (1000, 1100) SELECT * FROM `products_product` WHERE `products_product`.`brand_id` IN (1100, 1000) I have 3 databases for my Django project: read1, read2 and default. And the router selects these 3 databases randomly for reading and uses only default for writing. I designated default for some queries with using(), but it seems that using() does not use the default all the time. -
Django taggit related post not showing on template
Recently I installed django-taggit and included in the post model. I did the views and urls files and no error. On the home page I get a few posts and 10 tags related to posts. When I click on one of the tags it goes to the right slug but the page is blank. What am I missing here? Any help would be appreciated.

CBV: How To Make A Drop Down Database Query Using Django FormView
What I would like to do is have a dropdown list containing objects from a database. When the user selects an object, I would like the information displayed on the page. What I have been able to do is have the values shown in the dropdown list, but I have not been able to display the way I'd like. I've been trying to do so a certain way to hopefully be able to better control the look of the form. models.py class Vehicle(models.Model): make = models.CharField(max_length=20) model = models.CharField(max_length=20) def __str__(self): return self.make + ' ' + self.model class Package(models.Model): make_model = models.ForeignKey( Vehicle, on_delete=models.CASCADE ) name = models.CharField(max_length=20) price = models.IntegerField() views.py class VehicleCompareView(FormView): template_name = "main/somehtml.html" form_class = forms.CompareForm forms.py objectlist = forms.ModelChoiceField(queryset=models.Package.objects.all() \ .order_by('make_model__make')) html file <form method="GET"> <select class="form-control"> <option value="0" selected disabled>Select Vehicle 1</option> {% for q in form.objectlist %} <option value="{{q.name}}">{{ q.make_model__make }}</option> {% endfor %} </select> </form> <div> <p>Selected Vehicle: {{q.make_model__make}} {{q.make_model__model}}<br> Price: ${{q.price}} </p> </div> So let's start with what I have found that somewhat works from messing with the code. If I use {{form}}, I get the package list, but it only displays the package name of course. If I attempt … -
How To Make Form Field Read Only In Template Django
I am curious how I can make a field read only in my template below or via the form? <div class="column"> <label for="form.reference" class="formlabels">Reference ID: </label><br> <!-- <input type="text" value="{{ reference_id }}" readonly>--> {{ form.reference }} </div> forms.py class CreateManifestForm(forms.ModelForm): cases = forms.IntegerField(widget=forms.TextInput(attrs={'placeholder': 'Enter Cases'})) class Meta: model = Manifests fields = ('reference', 'cases', 'product_name', 'count', 'CNF', 'FOB') widgets={ 'product_name': forms.Select(attrs={'style': 'width:170px'}) } I know I could do it the way that I commented out in the template, but I don't want to specifically define the input field like that. So how can I make it so that ```{{ form.reference }} is read only? -

How to create signals with guardian and Django
After a user registers and answers a few survey questions for the site, then I want to give access to a view. I'm using guardian to provide access. Currently Django just takes me to a blank page, when I test this. This view asks users to answer a few questions and then I assign the permission view page to the user. Then in the view 'genre_book' I only want it to be viewable for users assigned with the view_page permission. This does not work, but generates a blank page. #view to create the guardian permission def agreements_page(request): if request.method == "POST": form = AgreementsForm(request.POST) if form.is_valid(): user = request.user if user.is_authenticated: agree = form.save(commit=False) agree.user = request.user agree.save() assign_perm('view_page', user, agree) return redirect('page') else: return redirect('other_page') else: form = AgreementsForm() return render(request, 'agreements.html', {'form': form}) Here is the view that I want to restrict to users who have filled the agreements form. @permission_required('view_page') def genre_book(request, pk): .... # this is a function that deploys the page -

Django with Postgresql: duplicated objects created on local machine and triplicated objects on remote server
I have a Django project with Postgresql on DigitalOcean. Strangely, when I create an object it's triplicated on the remote server and duplicated on the local machine. Here are my models. from django.db import models class Instrument(models.Model): id = models.CharField(max_length=4, blank=False, primary_key=True) def __str__(self): return self.id class Quote(models.Model): instrument = models.ForeignKey(Instrument, null=False, blank=False, on_delete=models.CASCADE, related_name='quotes') quote = models.FloatField(blank=False) timestamp = models.DateTimeField(auto_now_add=True) def __str__(self): return self.instrument.id; And this is how I create an object: q = Quote(instrument=Instrument.objects.get(pk='GBP/USD'), quote=1.2100) q.save() I tried creating objects in different ways: i = Instrument.objects.get(pk='EUR/USD') q = Quote.objects.create(instrument=i, quote=1,2000) I would appreciate any comments and ideas how to resolve it. -
How to implement a google-login for any google APIs in a Django wep-app?
I'm currently developing a Django web app that will allow users to sign-in with their google account and get access to their Google Calendar and Google Drive data. I already succeeded in doing so on another project in a front-end context using an Angular library called ng-gapi (GoogleAuthService) but I can't seem to find an equivalent for Django! All I was able to do for the moment is to implement a simple google login, but can't communicate with the different google APIs. I have tried to use a module called django-allauth but it only logs-in the user via google but without providing any useful information (like authorization tokens etc...) needed to grant the web app to communicate with the user's google data. {% load socialaccount %} {% providers_media_js %} {% load static %} <html> <body> {% if user.is_authenticated %} <p>Welcome {{ user.username }}</p> <a class="btn btn-warning" href="http://localhost:8000/accounts/logout/">Log out</a> <a class="btn btn-secondary" href="http://localhost:8000/show/">My Gigs</a> <p>You're logged in with {{ user.get_provider }} as {{ user }}.</p> <img style="max-width: 80px; padding:10px; margin-bottom:10px" src="{{ user.socialaccount_set.all.0.get_avatar_url }}" /> <p>UID: {{ user.socialaccount_set.all.0.uid }}</p> <p>Date Joined: {{ user.socialaccount_set.all.0.date_joined}}</p> <p>Last Login: {{ user.socialaccount_set.all.0.last_login}}</p> <p>{{ user.socialaccount_set.all.0.extra_data.name }}</p> {% else %} <a class="btn btn-primary" href="{% provider_login_url 'google' %}">Log in</a> {% … -
Postgres DB getting overloaded when generating a sitemap in Django
I am generating a sitemap for a Django model. However, the Postgres DB gets overloaded filtering the table we're indexing. This causes the site to experience downtime for hours, because the database is backed up. The exact query causing the issue is: Books.objects.all().exclude(has_kindle__isnull=True).order_by('-has_kindle', '-id').select_related('publisher') The table has 3M rows, and the results are about 300k, divided into separate smaller sitemaps, each with 10k links each. Is it normal for the query above to cause the database to totally seize up like that? Is there anything wrong with this query that could be optimized? Any and all ideas much appreciated! -

How to handle errors when using PasswordResetConfirmView
I am using django.auth.contrib as my session based authentication framework. I have successfully implemented a reset password feature via PasswordResetConfirmView which requires a valid token sent to a user's email to set a new password. path('password_reset/confirm/<uidb64>/<token>/', auth_views.PasswordResetConfirmView.as_view( template_name='accounts/password_reset/password_reset_confirm.html'), name='password_reset_confirm'), This works fine if the token is valid. However, if the token is not valid (e.g. incorrect or expired), then I predictably get an error: Reverse for 'password_reset_confirm' with arguments '('', '')' not found. 1 pattern(s) tried: ['accounts/password_reset/confirm/(?P[^/]+)/(?P[^/]+)/$'] What's the best practice to handle this exception for the user? Ideally I want to catch it and intercept it with "Sorry, your token is invalid." Is there an existing way to do this within the django.contrib.auth framework? Looking for the best DRY approach. -

For loop and django save not working with Django mail delivery system on live server
I have created a mail delivery system that can deliver tips to 3 different countries. Tips for all the customers are saved in a table which also includes the country. I call the function using the url http://127.0.0.1:8000/cls/mail/?region=Americas and pass the region via the URL. There are 18 customers from Asia and 79 from the Americas. The issue I'm facing is when this function is run it needs to find the tip sequence for that week and load it to the mail queue table. All of this works in the local host everything works perfectly fine. But when I load to the digital ocean server only the tips for American customer does not work. I get this error: This page isn’t working 167.71.231.108 didn’t send any data.

How to handle permissions/validation in django.auth.contrib
