How to login as another user using Django?
I've got a site being built on Django to replace a previous custom site built using straight PHP. The site is built so that a business owner can sign up for a master account and create user accounts for all his employees. The master account can then display a list of all their users and click on a certain button for each of their users and login as that user - no need to enter username or password. We set a few cookies that declare the current user is now the employee as well as another cookie that tells the system this is still a master account so there's a new button at the top that lets the user click it to go back to their previous master account session. I'm struggling how to accomplish this in Django. Everything is so modular, I'm not sure how to start a session for a new account without requiring the user to enter username and password again. -

Change what's displayed in a Django template using the Python variables
I have recently started working on some software that has been written in Python/ Django, and I am looking to change what information is displayed on one of the webpages. The page currently displays a number of tabs, with different information from the database displayed on each tab. The tabs are titled: Overview, Budget, Works, & Items. On the Items tab, there are four columns: Items, Initial Sum, Latest Sum, & Notes. There are views in the Python code that are used to set up what's displayed on each tab, and the one for the Items tab that I want to change is defined with: def report_ccis(request, project_id): """ CCI items styled for pdf """ project = Project.objects.get(id=project_id) budget = get_current_budget(project_id) cci_total_exc = budget.cci_total_exc_vat_final cci_grouped_items = budget.cci_items.all().order_by('project_room', 'name') context = { 'project': project, 'cci_total_exc': cci_total_exc, 'cci_grouped_items': cci_grouped_items, 'webview': 1, } try: context['current_budget'] = project.budget_versions.get(current_marker=1) #For option name/date on top of pdfs except ObjectDoesNotExist: pass if request.GET.get('stage') == 'pd': """ Render post deposit homepage """ context['html'] = render_to_string('costing/report2_ccis.html', context) context['active_tab'] = '4' return render(request, 'costing/reports_post_deposit.html', context) else: """ Render pre deposit homepage """ context['html'] = render_to_string('costing/report_ccis.html', context) context['active_tab'] = '5' return render(request, 'costing/reports_pre_deposit.html', context) I want to remove the 'Latest Sum' … -
How to define billing address in Paypal page for payments without login
I'm using paypal in my site in the checkout page and I already have the shipping and billing addresses set by the user in my site.

Django modelform widget readonly render text not input field
I have a modelform with readonly fields that render as a HTML input widget with an ugly 'no-entry' mouseover image (firefox) when the text inside the input box is selected - default behaviour for 'models.TextField' fields to render as input I believe. self.fields['project_path'].widget.attrs['readonly'] = True self.fields['media_path'].widget.attrs['readonly'] = True self.fields['responsible'] = SysEventChoiceField(User.objects.all().order_by('first_name')) I want to render the modelform with a mixture of read only fields as pure text without the input boxes in the form. The result should look something like this in html.. <p>D:\This\Path</p> <p>E:\This\other\path</p> <input value="Bob Smith" name="user"></input> -
Writing generic functions for all types of Django models
What I need to achieve is best described by example. Imagine that I have multiple models (let's say, model Task and model Animals) that have a field named foo and my goal is to perform identical set of MySQL transactions for all of these models. For example, I want to increment by one all the foos of a given instance along with subsequent instances (with larger id's). Something like: def example_view(instance): instance.foo = instance.foo + 1 instance.save() id = instance.id INSTANCE_MODEL.objects.filter(id__gt = instance.id).update(foo = foo + 1) The question is, is it possible in Django to write generic functions in a sense that I can use example_view with Animals, Tasks, etc, as long as all of them have fields mentioned in the view ? And if yes, what is the valid syntax for INSTANCE_MODEL.objects.... ? -

SSL error on Django app for Heroku deployment
I am trying to setup SSL for my Django app, using Heroku to deploy, and am getting an "Unknown SSL protocol error in connection to localhost:24466" when I run the "$ curl -v https://localhost:24466/" request from my local machine (ie cutting out the entire Heroku stack). My app runs fine on Heroku when DEBUG = True but gets a connection error when DEBUG = False and I believe this is the issue.

Django: Order by two fields (one nullable)
i have the following model class Model1(models.Model): parent = models.ForeignKey("self", models.SET_NULL, null=True, blank=True)` Sample data: [{'id': 1}, {'id': 2, 'parent': 1}, {'id': 3, 'parent': 1}, {'id': 4}, {'id': 5, 'parent': 1}, {'id': 6, 'parent': 3}, {'id': 7, 'parent': 4}, {'id': 8, 'parent': 3}, {'id': 9, 'parent': 1}] I would like to order each parent node with all it's children using the django ORM, the expected output for the sample data would be something like this: 1, 2, 3, 6, 8, 5, 4, 7, 9 for each parent show its children after them. Any ideas on how this could be done? I was thinking that maybe with some aggregated field and sorting by it, but i'm a bit stuck on this one. Thanks in advanced! -

Djando: prepare query but don't execute it
I am trying to make some efficient queries with Django in the following loop: for division in divisions: playoffs = league.playoff_set.filter(division=division, double_elimination=True) I thought maybe filtering playoffs before the loop by selecting only those with double_elimination=True would enhance it: playoffs = league.playoff_set.filter(double_elimination=True) for division in divisions: division_playoffs = playoffs.filter(division=division) But now I am concerned that this is firing the query from playoffs in every run at the loop instead of filtering on the previously retrieved result. Is it working as expected or as I am fearing? Should I use Q instead to build these better-performing queries? -

Problems using Ajax with Django
I am having problems trying to update a block of my site (which includes another templates) by issuing an Ajax call. The that needs to be updated works just fine, but the JS script that is inside that template does not work (before, I was just adding the full request to my template, but that caused to have twice the content of the parsed template, but JS scripts were working).

Django - Remove HTTPS redirect
I've a django app hosted on pythonanywhere servers. Some days ago, while editing this website, I've added in the settings.py file some variables about the https and ssl connection. Obviously I didn't want the https while I don't have the certificate, but I forgot those variable in the settings file. After the upload of files, going on the site, I saw that I've forgot those variables. I've immediatly deleted the variables from the settings file and re uploaded, but the problem persists. I mean, if I go to the site there is a redirect to https that I don't want. The outcome is "Connection is not private" whit a red barred https. Could you please tell me how to fix this problem? how to remove the automatic redirect to https and aboid the message "connection is not private" ? Thank you in advance!!! -

Redirect requests to Django application using Apache
I have an Apache web-server and a PHP application. It all works great. The httpd.conf file at this moment looks like so: ... LoadModule wsgi_module modules/mod_wsgi.so ...

So, when I go to localhost:8080, I see my PHP application running. Well done. Now, I have a second teene-weeny Django application. It's not even a full-blown application, because it's role will be to answer to one certain request from the same PHP application. Still, I will call it Django application. I run it like so: C:\django\project> python manage.py runserver 127.0.0.1:8081 As you can see I run a non-production server, but it works good. When I go to 127.0.0.1:8081, I see the result returned from my index view: def index(request): return HttpResponse("Hello, world") So, it's just a simple Hello world page and it works. Now what I want is to use Apache server, so that when I go to localhost:8080/django, I would see the very same Hello world page. I do not know how to implement …
