Why does my aging Django 1.3.1 site say ''TemplateDoesNotExist at /admin/" after migration to a new server?
I have a Django v1.3.1 site on a now-compromised server (used to be on Python v2.7.3).

How to query in django one to many
What I want to do? I have an app have three models:Series,Section and Episode,every one have a one-many query(by ForeignKey). just like this series-> many Section,section-> many Episode Now I will show a section with episodes information in series page, but it make more query. now code views.py series = Series.objects.get(id=series_id) section = Section.objects.filter(series=series) list.html {% for item in sections %} ... {% for episode in item.episode_set.all %} ... {% endfor %} ... {%endfor%} models.py class Section(models.Model): series = models.ForeignKey(Series) .... class Episode(models.Model): section = models.ForeignKey(Section) What I want to get ? an example code tell me how to query in views.py and use just little query. you can guess, in my code, if here are many section and many episode, it will have many query. Some idea. I use Laravel Before, In Laravel , it has a hasMany Function, I can use it to get other models items(Define by belongsTo). Is Django has same function? -

Why does Django AssertFormError throw a TypeError: argument of type 'property' is not iterable?
I'd like some help or advice on how to test for errors in one of my Django forms. It's responsible for ensuring the user enters a valid session ID which is used as a authentication token for a 3rd party API. Valid IDs are 32 characters long and alphanumerical. I've chosen an approach that validates the field, rather than the model. When I manually test this using the development server it works as expected. I.E. if the user pastes a string of the wrong length or with the special characters, the field's validate method creates errors which are then displayed via a for loop around the form errors in the html template. I don't understand the following error. I've temporarily modified testcases.py to prove that the errors are being passed to it - so why is context[form].errors a 'property' and how did it get there?

Django: Returning a template with POST parameters
I have a table with multiple rows, each of which has an 'edit' button. On clicking this button, the user should redirect to a form with his details already prefilled. Now, I have defined data attributes inside the 'edit' button's definition: <a href='#' class="edit-user" data-email="abc@gmail.com">edit</a> Using JQuery, I'm deriving the value of the 'email' data attribute and passing it in a POST request to /add-edit-user, which is also mapped to the page which has my form: $( ".edit-user" ).click(function() { var url = base_url + '/add-edit-user/'; var data = { 'email': $(this).data('email'), 'csrfmiddlewaretoken': csrftoken, }; // $.post(url, data); $.post(url, data).done(function(result) { console.log(result); }).fail(function(error) { console.log(error); }); }); The /add-edit-user URL maps to the following view where I'm trying to define my form object and pass on as a context variable to my template file: def add_edit_users(request): form = AddUpdateForm(request.POST or None) data = {'form': form} return render(request, 'add_edit_users.html', data) Now, my assumption was that if the user clicks on the 'edit' button, I'd set the 'email' parameter in a data attribute and pass it on in my POST request to /add-edit-user URL, after which I'll render my form template with the form object as a context variable which will display … -
How to delete arguments from url
I need to generate keys by clicking button and to show generated ones. Here my view: @user_passes_test(lambda u: u.is_superuser) def get_key(request): if(request.GET.get('create_new_key')): for_whom = request.GET.get('for_whom') create_key(for_whom) created_keys = RegistrationKey.objects.all() return render(request, 'registration/get_key.html', { 'created_keys':created_keys, }) And template: <!DOCTYPE html> <html> {% include "core/header.html" %} <body> <form action="#" method="get"> <input type="text" name="for_whom"/> <input type="submit" class="btn" value="Create" name="create_new_key"> </form> <ul> {% for created_key in created_keys %} <p>{{created_key.key}}</p> <p>{{created_key.for_whom}}</p> {% endfor %} </ul> </body> {% include "core/footer.html" %} </html> Now when I'm clicking the button on page http://127.0.0.1:8000/get_registration_key/ the key is generating but now I'm at http://127.0.0.1:8000/get_registration_key/?for_whom=&create_new_key=Create#, so refreshing this page would generate more keys. I really need to cut this arguments from url but don't understand how. -
ng-show not updating with $timeout function
I'm trying to write my own photo slider so that the image and text I have on my Django homepage will fade from one to the next (and then repeat). I created a timeout function to loop a $scope.current_slide variable from 1-3, and back to 1 at a set interval. I'm using ng-show on each so that when the $scope.current_slide variable is equal to the number of slide, each picture will appear. The problem I'm having: The images aren't cycling through when I use the timeout function. However! I know in theory my code should work because when I make a button, and use ng-click to allow the button to increment a an angular 'click' variable (1, 2, 3, etc.) the correct pictures show up. The pictures just don't scroll correctly with the timeout function. I added $scope.$apply() thinking this would fix it, but nothing changed. I have the JS file within my home.html page so that it can dynamically pull the total number of slides from Django. home.html <script> var myApp = angular.module('myApp', ['ngRoute', 'ui.bootstrap', 'ngAnimate']); myApp.controller('myController', ['$scope', '$timeout', function($scope, $timeout) { $scope.timeInMs = 0; console.log("We are here in CTRL Controller"); $scope.current_slide = 1; // FUNCTION EXECUTES EVERY FEW … -
django different domain url routing using {% url %} and app urls
How would I setup django url routing to reroute to a specific domain for each app's urls? Meaning: Let's say I have an app "Jobs" and I want to route to "jobs/list" to view a lsit of all jobs which is on domain: "(name)jobs.io" whereas my main app is on (name).io. These links are in the navbar. I've ported django-multiple-domains to Django 1.11 and have the setting, used by the middleware, setup to use each apps urls based upon the domain but this doesn't seem to take care of using the {% url %} tag. -

Django how to get record id from ModelForm
I've been banging my head on this for weeks but I am determined to get ModelForm to work! When you process a POST with data received from a ModelForm, I understand that you need to get the original record from the database and then create a new form using that original record as the 'instance'. This is documented in the Django docs as follows: >>> from myapp.models import Article >>> from myapp.forms import ArticleForm # Create a form instance from POST data. >>> f = ArticleForm(request.POST) # Save a new Article object from the form's data. >>> new_article = f.save() # Create a form to edit an existing Article, but use # POST data to populate the form. >>> a = Article.objects.get(pk=1) >>> f = ArticleForm(request.POST, instance=a) >>> f.save() In this example they know that the pk of the record they are looking for is 1. BUT, how do you know the pk if you're reading data from request.POST, assuming that the POST is based on data you previously wrote to the screen? ModelForm doesn't store the pk. So, from where do you pick this up? Without it, how do you know which record to pull out of the DB … -

multiple forms in Django createView class
I'd like to create a formView(based on Django build-in CreateView class) to allow creating new user records, which are from two different models. Both models sounds like one is user model and another is user profile model. I wish one form with one submit button to approach it, but I found only one form_class could be assigned in one createView class in Django. So I wonder is that possible to use CreateView to approach it? if not, any solution recommended? Appreciated if any assistance from you. -
Django - licensing application (connecting an app with particular domain)
I would like to sell my app. The only problem is to protect the source code. I would like to allow to use it with only one particular domain (one license = one domain). Is it possible to prevent reuse code on another domains? By now every user can change allowed host by simply editing setting.py file. I don't have any idea how can I prevent that. Is there any third party app for licensing functionality? -
Python/Django vs JS/HTML5 to build a CASAbrowser-like website?

Besides the GUI part (buttons, scrolls, ..) I want the freedom to add multimedia components (a video, a speech signal, ..) and scatter plots. -
Locally test different domain url configuration in Django
As the title says how do i test different domain not subdomain url routing? I'm using a middleware as follows: class MultipleDomainMiddleware(MiddlewareMixin): def process_request(self, request): url_config = getattr(settings, 'MULTIURL_CONFIG', None) if url_config is not None: host = request.get_host() if host in url_config: request.urlconf = url_config[host] Where the url_config[host] value points to app.urls in the settings MULTIURL_CONFIG dictionary. Each app is on a different domain. Now, when locally testing I'm on localhost:8000/ so how can I test this so I can test my routing schema as well as shared data across the domains locally? -
Python/Django: How to show both main model and 'foreign-key model' together in HTML
