Serve entirely static (documentation) website from Django url in Django 1.10
I am using mkdocs for a wiki documentation site that serves markdown tutorials and general information files created by various people. mkdocs ouputs an entirely static site in a site directory. Is there anyway to serve this site in django 1.10? I know you used to be able to do something like this: url(r'^docs/wiki/', 'django.views.static.serve', {'document_root': base.DOCS_ROOT, 'path': 'index.html'}), url(r'^docs/wiki/(?P<path>.*)$', 'django.views.static.serve', {'document_root': base.DOCS_ROOT}), but that no longer works in Django 1.10 because views must be callable lists or tuples. I would prefer to not serve this out of templates because the assets for the website in order not to split the assets mkdocs creates into the django static directory from the html files it creates that would presumably be in templates. error given if attempted to run server: raise TypeError('view must be a callable or a list/tuple in the case of include().') Any simple way to do this with urls? -

How do I use a dictionary from django in my google maps api?
I'm using the Google maps api and Django to build a web app. I want to display on the map some markers and infowindows that have information relating to my app. I have a dictionary in my views.py file that has the data I need, however I cannot use that dictionary because it does not work with javascript. How should I pass in my dictionary from views.py to the google-maps.html file, so that I can use it in my javascript code? -
Uploading a file to django model with a form - is_valid() fails
I'm trying to upload a file to a django model with a form, however it fails when it reaches form.is_valid(). I'm adding the form to a twitter bootstrap modal, which I guess could be causing issues? When I print form.errors, I get a message saying that the form is required. I'm obviously adding a text file to the form before submission, so I'm not sure what the issue could be. views.py - Successfully gets past 'request.method == 'POST'. Fails at form.is_valid() if request.method == 'POST': form = ConfigurationForm(request.POST, request.FILES) print("ERROR " + str(form.errors)) if form.is_valid(): print("Success") elif not form.is_valid(): print("Failed") forms.py from django import forms from .models import NetworkApplications class ConfigurationForm(forms.Form): config_file = forms.FileField(label="Select a file") class Meta: model = NetworkApplications In my template: <form method="post" enctype="multipart/form-data">{% csrf_token %} {{form.config_file}} </form> request.FILES seems to be empty. form.errors returns this: <ul class="errorlist"><li>config_file<ul class="errorlist"><li>This field is required.</li></ul></li></ul> -

jqte automatically removes a line when save
I'm using jquery-te 1.4.0 I have it on my django template, initialised like so $('#mytextarea').jqte(); My content would be like (a) Apple (b) Banana (c) Carrot Then made (a) Apple to bold or all items Save the form and it'd come out as (b) Banana (c) Carrot And when you add (a) Apple again, it'd delete some other lines or it won't add at all.

Django REST: Displaying a feed from a queryset and API JSON response
Currently I have a ListView which displays local posts class ListPosts(generic.ListView): queryset = Post.objects.filter(visibility='PUBLIC').order_by('-created_on') template_name = 'app/post_templates/list_posts.html' context_object_name = 'posts_list' paginate_by = 10 This works well, but I am not trying to incorporate responses from an API that gives the same info and more than is in our local Post objects, but of course needs some work to fit exactly. What is the easiest way to have both sources of information show up in the same stream (hopefully with pagination)? -
deploying to heroku from local machine
I have django project running on my machine in virtualenv. Is there a way I can deploy my project on Heroku directly?

Any guidance is highly appreciated. -
Django adding custom decorator to admin urls
I have a custom decorator that I implemented to use Duo Push 2FA. Which looks something like this: views.py @duo_auth.duo_auth_required def get_stuff(request): page = request.GET.get('page', 1) If it does not meet the requirements it'll bounce you to a page that requires you to authenticate via DUO. And I've gone as far as to decorate all my views with it, but when it comes down to the admin page, I'm not entirely sure how to integrate it there. urlpatterns = [ url(r'^admin/', admin.site.urls), Is it possible to add the decorator on the urls pattern? -
How do I re-evaluate my urls.py file after every test within a Django tests.py file?
I have the following construction in my urls.py - it allows me to visually check the format of emails that I send in the browser when I'm developing: urlpatterns = [Various url pattenrns] if settings.DEBUG: urlpatterns += [URL Pattern for checking emails] My issue is that when I run my test suite the code only checks settings.DEBUG one time - not each time a test or even a TestCase runs. I'm trying to use the @override_settings decorator before my tests that apply to the DEBUG=True urlpattern with something like: # Most of my tests run fine with Debug=False @override_settings(DEBUG=True) # Tests that use the URL pattern for checking emails However, I can't seem to get this to properly toggle the Url pattern between tests...presumably because my urls.py file only loads once for the entire app's tests. Is there a way to use this type of construction in my urls.py and run my tests? Is there a reason I shouldn't be using this type of conditional in my urls.py? -
Where do I put my django Template Context Processor setting in Django 1.10
I'm trying to migrate an old project over from Django 1.6 to 1.10. I have read the documentation but I am still having trouble understand how to handle Templates in my settings.py In my old settings I had: TEMPLATE_CONTEXT_PROCESSORS = [ "django.contrib.auth.context_processors.auth", "django.core.context_processors.debug", "django.core.context_processors.i18n", "django.core.context_processors.media", "django.core.context_processors.static", "django.core.context_processors.tz", "django.core.context_processors.request", "django.contrib.messages.context_processors.messages", ] How do I migrate this over to 1.10? Can I add it to the following? TEMPLATES = [{ 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [os.path.join(PACKAGE_ROOT, 'templates')], }] Currently when I run my Django project in 1.10, I get an error that says TEMPLATE_* settinsg were deprecated in Django 1.8 -

Obtain extended User parameters into template
I extended admin's User model with my OperatorProfile class in order to add an avatar and some other fields. My model looks like this: def user_directory_path(instance, filename): ext = os.path.splitext(filename)[-1].lower() name = 'operators/avatar/user_{0}{1}'.format(instance.user.id, ext) if os.path.exists(os.path.join(settings.MEDIA_ROOT, name)): os.remove(os.path.join(settings.MEDIA_ROOT, name)) return name class OperatorProfile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) avatar = models.FileField(upload_to=user_directory_path, null=True, blank=True) And my question is: what is the proper way to retrieve OperatorProfile additional information in admin template? Do I have to declare a new context processor or is there a way to extend user and obtain something like this? {% firstof user.get_short_name user.get_username %} <img src="{% static user.get_avatar %}" /> -
What happens when a Django table hits max on an ID/PK column?
Lets imagine that you have an application where an specific table has A LOT new objects (in Django terms) created. Nevermind how many are deleted, but let's say it is sufficient to keep the table functional. After quite a while, how unlikely it may ever be, the table hits max on the ID/PK column. What happens next? How does Django handle that situation? -
Django stopped finding application static files
I have a Django 1.9.8 app that's working most of the times. For some reason, Django stopped service application static files, including those of the build-in admin application. Running collectstatic only looks for files in my STATICFILES_DIR, as does findstatic. I do have django.contrib.staticfiles in my INSTALLED_APPS, and yet - Django does not look for its apps' static files. I'm stumped and don't even know where to look next. -

How to stop Django from escaping the # symbol
I am trying to use SVG sprites for the icons in a site, like this: <svg aria-hidden="true" class="icon"> <use xlink:href="{% static 'images/site-icons.svg#icon-twitter' %}"></use> </svg> However this doesn't work because the # gets escaped by Django and so I end up with: <svg aria-hidden="true" class="icon"> <use xlink:href="{% static 'images/site-icons.svg%23icon-twitter' %}"></use> </svg> So no icons are rendered. I have isolated that the problem is the escaping, since it works if I paste the contents of site-icons.svg in the template, and do <svg aria-hidden="true" class="icon"> <use xlink:href="#icon-twitter"></use> </svg> so the problem is in the escaping. Does anybody know how to avoid this escaping from happening?
