Django Polymorphic inline form
My Django-admin has a form that allows editing of articles. The articles may have Media objects. I use the django polymorphic class to allow Video, and Photo media. I can create or delete media objects fine using the inline class. But I also want to be able to select already created Media that is currently unassigned to any article. Ideally I want an inline form that lists all unassigned media objects and has a checkbox beside them so that I can add some to the currently being edited story. First, I don't know how to show unassigned media in my inline objects. Second how do I add a checkbox to their form to allow selecting or removing them. Thanks. -
custom exception handler for DRF response and Django response
I'd like to define a custom exception class and raise it. Django rest framework has a hook where I can define custom exception handler (http://www.django-rest-framework.org/api-guide/exceptions/#custom-exception-handling) Django also provides a way to do it via middleware. Question, is if I want to handle exceptions in drf views and regular django views, would it be sufficient to handle them in django middleware? Or do I need separate handler for DRF views? In other words, does DRF request/response goes thgrough django middleware as well or not? -

Django loop is returning multiple posts
I am trying to get django to display posts from a single catgory on that category's page, instead, it displays all the categories and the posts under each category in the template.

Queryset expression using List Comprehension [duplicate]

Django: point url behind root of app?
I am going through Django's tutorials (Django tutorial part 3) and I am at the part where we are adding views and urls. In this demo app they add subviews for polls, e.g. /polls/34/ to get to the 34th poll. Quoting from the tutorial: When somebody requests a page from your website – say, “/polls/34/”, Django will load the mysite.urls Python module because it’s pointed to by the ROOT_URLCONF setting. It finds the variable named urlpatterns and traverses the regular expressions in order. After finding the match at '^polls/', it strips off the matching text ("polls/") and sends the remaining text – "34/" – to the ‘polls.urls’ URLconf for further processing. There it matches r'^(?P<question_id>[0-9]+)/$', resulting in a call to the detail() view like so: My question is as follows: suppose you have a view that is related to your app, but where the url - prepended by the app name - makes less sense than just the new view by itself. How could you make a view (which is part of the app) start at a new path name. This might be confusing so here is an example. Suppose you have an app (decks) for decks users make out … -
How do I get AWS credentials in the AWS ECS docker container?

error 'makeHalloRichTextEditable is not defined' with Django form in Wagtail 1.10.1
I'm running Wagtail 1.10.1 on Django 1.11.1 and Python 3.5.2. I have a Django form for people to submit pages to the website without being users. It was working until a month or so ago and broke some time after I upgraded from Wagtail 1.8. The error message on my dev machine (localhost) is Uncaught ReferenceError: makeHalloRichTextEditable is not defined at localhost/:136 The relevant part of the form HTML looks like <label for="id_body">Content of the item.</label> <textarea name="body" cols="40" id="id_body" rows="10"> </textarea><script>makeHalloRichTextEditable("id_body");</script> In the template that section looks like {{ form.body.label_tag }} {{ form.body }} {{ form.body.errors }} The relevant bit of the models.py file is class NewsPage(Page): body = RichTextField(blank=True) submitted_by = models.CharField(max_length=255) submitter_email = models.EmailField() I found https://github.com/wagtail/wagtail/pull/2673 which seems relevant, but I haven't figured out how to make sure the correct JavaScript files are imported, or what else might need fixing. What's the best way to figure out how to fix this? -

django redirects different links to same page
from django.shortcuts import render, HttpResponse # Create your views here. def index(request): return render(request, 'platoweb/index.html') def about(request): return render(request, 'platoweb/about.html') This is the views.py file. from django.conf.urls import url from . import views urlpatterns = [ url(r'^$', views.index, name='index.html'), url(r'^$', views.about, name='about.html'), ] This is the app urls.py from django.conf.urls import include, url from django.contrib import admin from django.conf import settings from django.conf.urls.static import static admin.autodiscover() urlpatterns = [ url(r'^platoweb/index.html', include('platoweb.urls')), url(r'^platoweb/about.html', include('platoweb.urls')), url(r'^admin/', admin.site.urls), # . url(r'^posts/', include("posts.urls", namespace='posts')), ] if settings.DEBUG: urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) This is the global urls.py Essentially, I'm trying to hit two different urls, index.html and about.html (and more later). However, when I run it, both index.html and about.html redirect to index.html. I've tested both html files and they work just fine. Any ideas or thoughts? -
Django: adding multiple values to a model's field
I am new to Django. I am trying to create an app with news, and the companies mentioned in those news, and have created the following models: class Company(models.Model): company_name = models.CharField(max_length=100) company_country = models.CharField(max_length=50) def __str__(self): return self.orgn_name class News(models.Model): news_title = models.CharField(max_length=200) news_link = models.CharField(max_length=100) news_date = models.DateField() news_company = models.ManyToManyField(Company) def __str__(self): return self.news_title Now, a news might have mention of more than one company. How do I account for that, and enter the list of companies in the database entry? I am using the default Sqlite DB right now. E.g. a news can be "Facebook competes with Google in AI space" This news has two companies: Facebook and Google. 1) How do I design my models so that they take multiple values for Company? 2) How do I save those values via shell? 3) How do I query it, so that a query similar to SELECT COUNT (DISTINCT 'Company').... should output Facebook and Google separately, and not as "Facebook, Google"? I am stuck here and desperately need some guidance. TIA
