Wagtail: render a page programmatically in a Class Based View
I've got a Wagtail setting where a user can select a page to render, and if it is not set, it returns a listing page using ListView of recent posts. Here is the setting: @register_setting class PeregrineSettings(BaseSetting): """ Settings for the user to customize their Peregrine blog. """ landing_page = models.ForeignKey( 'wagtailcore.Page', null=True, blank=True, on_delete=models.SET_NULL, help_text='The page to display at the root. If blank, displays the latest posts.' ) The setting works. When I try to use it in the ListView, I'm attempting to pass the url_path to Wagtail's serve method, but it doesn't render the page view; I get a 404. Here's the code of the ListView: class PostsListView(ListView): """ Paginated view of blog posts. """ model = SitePost template_name = 'peregrine/site_post_list.html' context_object_name = 'posts' paginate_by = 10 ordering = ['-post_date'] def get(self, request, *args, **kwargs): peregrine_settings = PeregrineSettings.for_site(request.site) if peregrine_settings.landing_page is None: # Render list of recent posts response = super().get(request, *args, **kwargs) return response else: # Render landing page serve(request, peregrine_settings.landing_page.url_path) It feels like I'm missing a way to just pass the Page instance stored in peregrine_settings.landing_page to a method to render. Can anyone shed some light on the internals at work here? Thank you! -
Test Application Keys for Twilio Authy Client

Where or how do I get this test Application Key? -
Django Iterating over Many to Many Objects
My main problem is that my code never goes into the for loop though within the debugger I can see that hardware exists. The for loop gets just skipped and I can´t figure out why this is the case. Models: class Hardware(models.Model): name = models.CharField(max_length=30) description = models.TextField() class Bundle(models.Model): name = models.CharField(max_length=30) description = models.TextField() devices = models.ManyToManyField(Hardware) class BundleForm(ModelForm): class Meta: model = Bundle fields = ('name', 'description', 'devices') labels = { 'name': _('Bundlename'), 'description': _('Beschreibung des Bundle'), 'devices': _('Hardware im Bundle') } Views: elif request.method == 'POST' and 'newbundle' in request.POST: form = BundleForm(request.POST) if form.is_valid(): bundle = form.save(commit=False) bundle.save() for hardware in bundle.devices.all(): print(hardware) messages.success(request, 'Erfolg! Die Daten wurden erfolgreich gespeichert.') return redirect('/knowledgeeditor/bundle/', {'messages': messages}) -

Multiline Charfield Django
How can I make a multi-line CharField in a model form in Django? I don't want to use Textarea, as I want the input to be with limited length.

How does one build an spa with webpack when deploying Docker container to Heroku
I'm developing an Aurelia Single Page App that will talk to a REST api built with Django Rest Framework. Without containers, I would have two buildpacks, one for Node that runs a script in the package.json file and another for Python that builds the Django app. If I push a container image, then what mechanism replaces the node buildpack that calls the script in package.json to trigger webpack to create the asset bundles? -
How to separate a Django app in order to make part of its GitHub repo private
I have hired a contractor to do some web development work on my app and would like to only give them access to certain parts of my GitHub repo (I would like to keep the Python utility files private). The stack is Python/Django/GitHub/Heroku. Based on other SO posts, it sounds like the solution is to create two GitHub repositories, one which is public and the other which is private, and then manage these two repos via Git. The problem is that if I move the Python utility files to another repo, outside of my Django root project, then I'm not sure how to import those files into my Django project. I went down the route of moving the Python files to an external location and then trying to import them via sys.path.append('/mypath') in the Django settings file and alternately tried packaging my python files into a separate module and then installing it via pip but have run into issues with both of these methods. Is there a suggested approach for how to best separate these two parts of the code base, such that the Django project is able to import the Python files? -

I'm trying to create a logic in Django which checks if User had already provided certain information. If not then it creates new object and save in the databse.

Why pip freeze >requirements.txt return Permission denied
When I worked in a virtual environment, I installed my packages django-2.0 there. Yet it is installed globally: sudo virtualenv -p /usr/bin/python3.5 ~/.virtualenv/venv source ~/.virtualenv/venv/bin/activate (venv) $ pip install django==2.0 And I had django-1.11 in my global environment before. However django-1.11 is also hoping to be installed into the other virtual environment, but it was also installed globally. I uninstall this package, and try to install it into my virtual environ again. but it seems like not work at all. All package installed newly were in global env. Now i want to use pip freeze >requirements.txt to get requirements file,but it return : (venv) $ pip3 freeze >requirements.txt bash: requirements.txt: Permission denied (venv) $ sudo pip3 freeze >requirements.txt bash: requirements.txt: Permission denied I thought maybe it was because that i install these package globally?I don't know. How can i install package into my virtual environment correctly, and get requirement file:( -

How To Save A User's Favorite Posts in Django
So, i'm trying to allow a user to favorite a post (in my case Deals), which will later be displayed on their profile page. The problem I'm having --If I look in the Django admin, under a specific user for the 'favorites' field, ALL of the Deals are appearing. I got my initial inspiration from this post here So i added a 'favorites' field to my User model with a Many to Many relationship on my Deal model...like so: favorites = models.ManyToManyField(Deal, related_name='favorited_by') My html template where a user can favorite a 'Deal' looks like this: <form id="favorite{{deal_detail.id}}" method="POST" action="{% url 'deals:favorite' deal_detail.id %}"> {% csrf_token %} <input type="hidden" name="supporttype" /> <input type="submit" value="Add Deal to Favorites" /> My url for favorites is this: url(r'^(?P<pk>[0-9]+)/favorite', favorite, name='favorite') this is the view for 'deal_detail' and 'favorite' def deal_by_detail(request, slug): deal_detail = Deal.objects.get(slug=slug) return render(request, 'deals/deal_detail.html', {'deal_detail': deal_detail}) def favorite(request, pk): if request.method == 'POST': deal = Deal.objects.get(pk=pk) deal.save() messages.add_message(request, messages.INFO, 'Deal Favorited.') return redirect('home') -

How can I compare two Django QuerySets and return QuerySet with replacement of the same values from second in first?
My env is Django 2.0.2 and Python 3.6.1. How can I compare two Django QuerySets and return QuerySet with replacement of the same values from second in first? For example, I have QuerySets: >>> qs_local = PriceLocal.objects.filter(user_id=request.user.id) >>> print(qs_local) [{ 'user_id': 1, 'product_id': 1, 'price': 100 }] >>> qs_world = PriceWorld.objects.all() >>> print(qs_world) [{ 'product_id': 1, 'price': 300 }, { 'product_id': 2, 'price': 500 }, ... ] I want to compare this Django QuerySets and return QuerySet, like this: [{ 'product_id': 1, 'price': 100 }, { 'product_id': 2, 'price': 500 }, ...] At this point, we are replacing the same records (with 'product_id': 1) from second to first QuerySet.
