Add current site's domain to template dirs
What is the correct way to prepend an extra, site-specific templates directory to the template dirs setting in Django? TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [ <PREPEND SITE-BASED TEMPLATE DIR IN HERE> str(APPS_DIR.path('templates')), ], 'OPTIONS': { 'debug': DEBUG, 'loaders': [ 'django.template.loaders.filesystem.Loader', 'django.template.loaders.app_directories.Loader', ], 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.template.context_processors.i18n', 'django.template.context_processors.media', 'django.template.context_processors.static', 'django.template.context_processors.tz', 'django.contrib.messages.context_processors.messages', ], }, }, ] I obviously can't use Site.objects.get_current() in there. I could write my own template loader which uses it but is that "correct"? Or should I be using an extended version of the settings files or something? -
how to return redirect to previous page in Django after POST request
I'm coding a news website,in the detail news page ,there is a comment fountain,if people want to post comment they need to login first.And I want to make it that,after they login in successfully ,the page can return to previous news page.

Different User proxy model per app in request object
Current situation I have 3 apps in my Django project: auth, polls and school. AUTH_USER_MODEL in my settings is auth.models.User, and it is shared between all apps. the login/ URL in urls.py is also shared between the 3 apps. What I need to do I want to add some methods only to the users of the school app. To do this, I created a school.models.User model with proxy = True meta. This model inherits from auth.models.User. Problem When a user logs in, request.user contains a "base" auth.models.User object, independently of which app the user is using. How can I populate request.user with a different user model, depending on the app? I tried using a custom Authentication Backend as suggested in Django - User proxy model from request, but I have no way to detect which app the user is using, so I can't seem to discriminate between polls and school in the authentication backend. -

ajax POST for data which contains an array with jQuery and Django
So I'm looking to take data for checkboxes which have been checked, and I'm pushing these values to an array: var interestedIn = []; $(":checked").each(function() { interestedIn.push($(this).val()); }); I'm then passing this array as data to be POSTED by ajax call with some other variables: $.ajax({ type: "POST", dataType: "json", url: "{{ request.path }}", data: { 'email': values['email'], 'name': values['name'], 'interestedIn': interestedIn } }) I'm trying to then access the interestedIn variable with a Django views.py file: if request.POST and request.is_ajax(): interestedin = request.POST.get('interestedIn') When printing the interestedin variable to inspect, this is coming back as None. Does anyone know how you post arrays and variables simultaneously? -

Django: Parsing data from multiple identical forms in one POST request
I have a basic form class form, and a page which generates multiple form with a single submit button (since every individual form is required). Everything works as intended. When a user clicks submit, all of the data from all of the forms is sent as a POST. This means, given form x3, the POST data can look something like: request.POST.getlist('number') = [1, ,,2] request.POST.getlist('animal') = ['dog', 'cat', 'pig'] request.POST.getlist('name') = ['charles',,,] I can restructure things so that this kind of information retrieval is easy, but then form-validation doesn't work too hot. Right now I'm doing something like this: submitted_forms = [] for ii in range(len(request.POST.getlist('number'))): tmp_values = {} for key in request.POST: if key != "csrfmiddlewaretoken": tmp_values[key] = request.POST.getlist(key)[ii] submitted_forms.append(Form(tmp_values)) # Validate all forms for form in submitted_forms: if form.is_valid(): form.save() This'll work great if things are all nice and clean, but it doesn't pop up w/ the validation messages (I believe it's because, in recreating the forms this way, I lose the association between the empty form the user is filling in and the form that gets posted). -

Can Django-Rest-Framework (DRF) Views and Serializers replace Django native views and forms
I am developing a website where i have to show 1) web pages with html content-type 2) also provide api json end points to develop web or mobile apps. Presently for html web pages i have used djangos views and forms. And for api i was using Django rest frameworks views and serializers. But after going through DRF i have found that DRF can render multiple formats. HTML & Forms REST framework is suitable for returning both API style responses, and regular HTML pages. Additionally, serializers can used as HTML forms and rendered in templates. http://www.django-rest-framework.org/topics/html-and-forms/ You can use TemplateHTMLRenderer either to return regular HTML pages using REST framework, or to return both HTML and API responses from a single endpoint. http://www.django-rest-framework.org/api-guide/renderers/#templatehtmlrenderer Since with one view (one endpoint) i can get both the html and api will that not make my coding efforts less. I am planning to use only DRF views and searializers instead of DJango forms and views for any type of content. What will be the setbacks if I only use DRF. -
