Migrating Django from 1.9 to 1.11: forms.MultiWidget.format_output disappeared
This method was very usefull to render MultiWidget in Django 1.9: format_output(rendered_widgets) I use it in many places, here is an example of use: def format_output(self, rendered_widgets): items = [ '%s %s' % (rendered_widgets[i], f) for (i,f) in enumerate(self.fieldnames) ] if self.aligned: return '<li>' + '</li><li>'.join(items) + '</li>' else: return ' '.join(items) It disappears in Django 1.11, and I don't find a natural replacement. The render method seems to be the unique alternative, but I don't understand how to use it correctly. Does anybody have ideas? -
Django call script in view from template
I have a view, that displays entries from one date to another, about a certain project. The project model is called "DNN" and times on there are in the "Vnos" model. views.py: def po_nalogu(request, dnn = None): dnn = None form = PregledDNNForm( request.GET or None, ) from_date = get_month_start(timezone.now()) to_date = from_date + relativedelta(months=1) if request.GET: if form.is_valid(): from_date, to_date, dnn = form.save() entries_qs = Vnos.objects.filter(dna__dns__dnn = dnn) month_entries = entries_qs.timespan(from_date, to_date=to_date).order_by('start_time') sestevek = 0 for entry in month_entries: sestevek = sestevek + entry.hours template = 'porocila/po_nalogu.html' context = { 'form' : form, 'from_date': from_date, 'to_date': to_date - relativedelta(days=1), 'entries': month_entries, 'sestevek' : sestevek, } return render(request, template, context=context) Now, I want to add a conditional sentence, so I could print PDF. Is there a way to add something like: if request.method == "PDF" do code and in template: <form action="" method="PDF"> <input type="submit" /> </form> I don't want to do a separate view for the PDF file, because of the from and to dates, as it is a lot of computing one more time. Thank you -
Is there any way to separate py and pyc files while building Django project using pybuilder
I was trying to build a Django project using pybuilder where I need to separate the pyc files and resource files. This is regarding protecting the source code, I know we can achieve this by the licencing mechanism. Our requirement is distributed the pyc file to the client instead of actual py file. -
How to allow googlebot to crawl publically visible pages on my django site that are behind login?
I've found several posts about this but can't seem to get a straight answer for my case. I'm using django allauth to make users sign up before posting anything. However, all the pages are visible to the public and don't require login to view. How do I allow google to crawl the pages without having to go through the login? Would a simple sitemap work? I looked into first click free but from what I read it only crawls the first page after the login? Or should I whitelist the IP's? Any direction would be great, thanks. -

I need to paginate a very large result (300,000 rows) but I don't want to run the query again.

No module named admin_view_permission, CircleCI?
When I run my Django project on CircleCI I get the following error: "ModuleNotFoundError: No module named 'admin_view_permission'" The project runs with no problems locally on my computer. I added the module admin_view_premissions, to settings, from this page: https://github.com/ctxis/django-admin-view-permission Then I ran "pip install django-admin-view-permission", and it worked fine. The migration also did not have any problems. Does anyone know why CircleCI is not able to find the module? Thank you for your time! -
Django messages are not shown if chrome data saver is enabled
Google data saver compresses data to reduce traffic usage. It is enabled by default in mobile (android) chrome and might be used in desktop chrome as plugin. Whe GDS is on django messages are NOT displayed. I created a sample application (Python 3.5, Django 1.10.8, uwsgi+nginx) to catch this bug. This app has one "submit" button on main page that triggers the view method: def welcome_view(request): if request.method == 'POST': messages.add_message(request, messages.INFO, "succeed") return HttpResponseRedirect('/') else: return render(request, 'index.html') Full app sources are here. Deployed application available at fqtest.ru Steps to reproduce: Deploy to some server (or use mine fqtest.ru). Don't forget to specify allowed hosts in settigs.py. Turn off chrome data saver plugin if you have it or use launch ingognito mode. Open main page and click Go bitton. Result: message shown as expected Turn on data saver plugin or install it (or open site from android chrome) Open main page and click Go bitton. Result: message NOT shown while it should be. Questions: What are reasons of this behavior? How can it be fixed/worked around? Hope for help. Thanks! -
How to query PointField - MongoEngine

How to display instances from two different django models on the same template, inside the same table?
In a django app I've created different models and everything looks okay until I try using data from two different models inside the same table. To sum it up: in the homepage, I need to create a table that contains data from both the models, ordered by date. The two models I need to display are the following. models.py class Document(models.Model): number = models.CharField(max_length=10) description = models.CharField(max_length=50) assigned = models.BooleanField validity_date = models.DateField is_issued = models.BooleanField class Program(models.Model): name = models.CharField(max_length=25) description = models.CharField(max_length=100) validity_date = models.DateField Then, I tried to create a view that would allow me to work with different models. This is my view.py: class BaseView(generic.ListView): template_name = 'base/base_list.html' context_object_name = 'base_list' def get_queryset(self): queryset = Document.objects.order_by('due_date') return queryset def get_context_data(self, **kwargs): context = super(BaseView, self).get_context_data(**kwargs) context['Programs'] = Program.objects.all() context['Employees'] = Employee.objects.all() return context Now how can I create inside the template a table that shows both the models at once, ordering each entry by validity date (no matter if the entry belongs to Program or to Document)? Thank you in advance!
