How can I add a static .txt file inside a text area using Django tags?
So I have this text area: <textarea id="input_txt" name="file_txt" class="input_size" rows="5" form="store" style="font-size: 11pt;" default_text="{{ file.txt }}">{% if store.file %}{{ store.file }} {% else %}{{ file.txt }}{% endif %}</textarea> I want to add a default txt file inside a text area if store.file is empty. Is there a way to add the text file inside the text area using Django Tags? -
redirect django runserver output in order to debug with pudb
I'm currently trying to use pudb to troubleshoot a django application. In order to do so, I'm running the runserver instead of gunicorn. Then, when I want to debug, I added: import pudb; pu.db The pudb gui shows up correctly but is quickly garbled by the runserver output. As per pudb documentation, I can avoid this by setting the PUDB_TTY variable before starting the server. $ tty /dev/pts/3 $ PUDB_TTY=/dev/pts/3 manage.py ... runserver ... Unfortunately, the GUI still gets garbled by the output of the server. Alternatively, I tried to redirect all output from the runserver (>/dev/null 2>&1), but the pudb output also get caught (obviously). Is there a way to: have the runserver not produce any output? tweak pudb ? -

Django REST Framework Web Login not working
I can't seem to figure out why my rest framework login in my django project won't work... I have got the log in link there and all and it does redirect me to the rest login page but after filling in my credentials and clicking login it just takes me back to the page I came from but it does not seem to authenticate me as it still says "Login" in the top right corner... I would expect it to change to "admin" in this case as I am trying to login using my superuser named "admin"... I am surely missing something.. Here are my REST Urls path("rest/auctions", auction_list, name="auction-list"), path('rest/auctions/<int:pk>', auction_detail, name="auction-detail"), path('rest-auth/', include('rest_framework.urls', namespace='rest_framework')), The rest-auth/ one I know is the one that somehow adds the login button and all (Magic?) But maybe I have to do something else too to make it authenticate? I don't know... I am using the built in django authentication system and User model. views.py @api_view(['GET']) def auction_list(request, format=None): if request.method == 'GET': query = request.GET.get('q') if query is not None: auctions = Auction.objects.filter(Q(title__icontains=query), deadline__gte=timezone.now(), status=Auction.STATUS_ACTIVE) else: auctions = Auction.objects.all() serializer = AuctionSerializer(auctions, many=True, context={'request': request}) return Response(serializer.data) serializer.py class AuctionSerializer(serializers.ModelSerializer): winning_bid = … -
Using join of temporary table as an alternative of `IN` in Django
In Django it's common to do the following MyModel.objects.filter(id__in=[huge array]) However it's not very efficient as described in the following answer here: https://dba.stackexchange.com/questions/91247/optimizing-a-postgres-query-with-a-large-in What would be a good way of replicating the above answer in Django given that you are using the ORM. Or would you have to drop down to raw sql for the entire query. What I'm looking for is if you have a queryset, is there a good way of joining that queryset with a temporary table that you created (possibly in raw sql). -

handling kwargs in POST and CBV
In my last question, I had trouble displaying imported choices in a select widget because I was missing a (should have been) obvious bit of code. Now, my GET (seems to) work just fine. The problem is I am doing something wrong in my POST. What I can't figure out is how the kwargs should be handled in POST. If I include kwargs in my post method in the line form = Enter_SW_Room(request.POST, **kwargs) I receive the error "init() got multiple values for argument 'data'". Looking around stack overflow, I find most of the problems with this error stem from calling self in super (or other calling errors). E.g. this problem / solution. If I try to work around this problem by NOT passing kwargs, the validation fails. (I think because there is now a value for the appropriate field, but the choices are gone.) So, what I figure is that either I'm doing something simple but importantly wrong again, or I need to modify the form validation. (or ???) Here's all the code (snipped for brevity): ''' views.py ''' class DockingBay(FormMixin, TemplateView): form_class = Enter_SW_Room def get_form_kwargs(self): kwargs = super().get_form_kwargs() # snip; create my_avatar_choices, which is more than just … -

Form validation error not being raised in django

Setting the string representation of models.DateTimeField()
I'm trying to set a __str__ function for a DateTimeField in a Django model. I've found how to do it for a full model, but not for a DateTimeField. Right now datetime fields are being sent to the template as: 2018-10-24T13:31:06Z Do I have to create a custom field, inherit DateTimeField, then set the __str__ method there? If so, any code to help? This is for an API which doesn't use a template, so I want to solve this in models.py, not with template filters. -
Django: create view inline generic update view
I am working on Django 1.11. I have two models, the first one has a foreign key like this : class Book(models.Model): name=models.CharField(max_length=100) owner = models.ForeignKey(Owner, on_delete=models.PROTECT, null=True, default=None) other_properties class Owner(models.Model): some_property I use the generic.UpdateView to update my Books : class BookUpdateView(generic.UpdateView): model = Book fields = ['owner'] This works but now I want to create an Owner from the BookUpdateView page, and then modify the book to set the owner property to the newly created Owner. Is it possible to have an inline form to create an Owner inside the BookUpdateView ? (not in the admin pages) Or maybe to have a separate create view for the owner which redirect to the BookUpdateView from where it was called. But only when it was called from there ? Thanks for any suggestion! -
Resolving URL based on Requesting Namespace
I am building a website that has about 10 instances of the same app. These different instances will just be used to serve different files on different pages. Everything is working except when I go to a different instance of the application and go to the detail view it reverts back to the original application's URL and namespace. For example, going to /university/term-syncc/ and clicking on an item in the list view redirects me to /marketing/4/ or whatever the ID is of that item. If I go to /university/term-syncc/4/it works but I cannot get that URL to resolve automatically. I know it has something to do with my get_absolute_url calling the assets namespace but how can I force it to check the current app namespace and then run a reverse from there? models.py def get_absolute_url(self): return reverse("assets:asset_detail", kwargs={"id": self.id}) HTML <li> <a href="{{obj.get_absolute_url}}">{{ obj.name }} test</a> </li> urls.py url(r'^$', asset_list_view, name="asset_list"), url(r'^(?P<id>\d+)/$', asset_detail_view, name='asset_detail'), -
Django how to handle two forms with one-to-many relationship between models in one post
For the sake of simplicity, here is a short version of the issue I am dealing with. Say you have two models, Product and ProductPricing, with Product having many ProductPricing instances and a product pricing is related to only one product (one-to-many relationship). The model's clean method: models.py: class ProductPricing(models.Model): product = models.ForeignKey(Product, related_name = 'prices', verbose_name = 'Price', blank = True, null = True) customer = models.ForeignKey(Customer, related_name = 'customer_pricings', blank = True, null = True) ... def clean(self): if not self.product and not self.customer: raise ValidationError(_('Pricing requires either a product or a customer. None is provided') ) forms.py: class ProductPricingAddonForm(ModelForm): class Meta: model = ProductPricing fields = ['UOM', 'cost_per_UOM', 'product'] Now, In my UpdateView, I am doing something like this: class UpdateProductView(View): template_name = 'product.html' product_form = ProductForm pricing_form = ProductPricingAddonForm def get(self, request, *args, **kwargs): product_id = kwargs.get('pk', None) product = Product.objects.get(id = product_id) product_form = self.product_form() pricing_form = self.pricing_form() c = {} c['product_form'] = product_form c['pricing_form'] = pricing_form return render(request, self.template_name, c) def post(self, request, *args, **kwargs): ''' To update both the models in one go''' product_id = kwargs.get('pk', None) product = Product.objects.get(id = product_id) product_pricing = ProductPricing.objects.filter(product = product) product_form = self.product_form(request.POST if any(request.POST) else … -

I plugged in i18n patterns module to my urls and added some languages: urlpatterns += i18n_patterns( path('blog/', include('blog.urls')), path('contacts/', include('contacts.urls')), path('signup/', views.signup, name='signup'), path('login/', auth_views.login, {'template_name': 'login.html'}, name='login'), path('logout/', auth_views.logout, {'next_page': 'login'}, name='logout'), ) LANGUAGES = ( ('ru', 'Russian'), ('en', 'English'), ('es', 'Spain'), ) But the only language I see in urls its a language that I set up in LANGUAGE_CODE parameter and the only valid link I have it is a link with a language_code parameter. For example, now I see 'en', but I need to see 'ru' and 'es' and etc.. What should I need to do with it in order to get all another languages here? If I set up a prefix_default_language=False, so I couldn't even get a default language (and all others respectively) [name='home'] languages/ admin/ en/ ^media\/(?P<path>.*)$ -

Using the django admindocs without adding 'contrib.admin' to the INSTALLED_APPLICATIONS
we want to document a little bit of our application for the customers prosumers. But we don't want to expose the whole admin interface or include that whole block of code in our production environment. What approaches could we look at to add the admindocs (django docs for this) without adding the admin site? The reason this is asked is due to the fact that a removal of the django.contrib.admin app leads to Django Version: 1.10.5 Exception Type: TemplateDoesNotExist Exception Value: admin/base_site.html Exception Location: /usr/local/lib/python3.5/site-packages/django/template/engine.py in find_template, line 146 Python Executable: /usr/local/bin/python -
