Django pass Python Object from view to Javascript script in template
This is a simple code created only to show the probem, obviusly the task that this simple code is trying to do can be done without Javascript, but I need to know how I can do this using Javascript, because In my real code I need it, and It cant't be done without Javascript (basically I create a dinamic 2D array with information from the view) in view.py in def play_game function ... players = Player.objects.all() context = { 'players' : players } return render(request,'play_game.html', context) in model.py class Player(models.Model): game = models.ForeignKey(Game, on_delete=models.CASCADE, blank=True, null=True) loose = models.IntegerField( default=0) win = models.IntegerField(default=0) name = models.CharField(max_length=9) In play_game.html <script> var players = "{{players}}"; for (player in players) { document.write(player.name); document.write(" Win:"+ player.win); document.write("Loose: " + player.loose); }; </script> -
django login required for the entire site not working
I am trying to use a code to force login if a user is not authenticated yet. I have tried too many codes and I could not get them working since most of them written in older versions of django. I am using django 1.10.3. I am not getting any errors when running the server, but I am not getting redirected to the login page too while I am not logged in. I am not even sure we can have both MIDDLEWARE AND MIDDLEWARE_ClASSES in the setting file. Any help would be appreciated. I also would like to have exceptions where I can make some of the views public that requires no login middleware.py: from builtins import hasattr, any from django.http import HttpResponseRedirect from django.conf import settings from re import compile from django.core.urlresolvers import reverse def get_login_url(): return reverse(settings.LOGIN_URL_NAME) def get_exempts(): exempts = [compile(get_login_url().lstrip('/'))] if hasattr(settings, 'LOGIN_EXEMPT_URLS'): exempts += [compile(expr) for expr in settings.LOGIN_EXEMPT_URLS] return exempts class LoginRequiredMiddleware(object): """ Middleware that requires a user to be authenticated to view any page other than reverse(LOGIN_URL_NAME).

django model formset update only
I want to use ModelFormset to update table data. Each row on picture contains one form with two fields, and one field in form required. I don't want to use empty form to create new object and can just remove it from rendering in template, and subclass save method to save only forms with initial data from queryset: class MyFormSet(BaseModelFormSet): def save(self, commit=True): if not commit: self.saved_forms = [] return self.save_existing_objects(commit) but empty form still need to be validated, and i got validation error on required field. How can i disable using/validating of "new object" form? -

Can I use sendmail for Django's send_mail?
I am setting up a Django-based hobby site on a VPS, and I am confused with Django's email system configuration. My server is successfully sending me technical emails (e.g. from fail2ban) using sendmail. However all Django-related googling mentions postfix, e.g. in this other answer. I wonder: If I can use sendmail rather than postfix; How I can configure Django to use my server's mailing functionality. Any help is much appreciated. FWIW, I am on Ubuntu 16.04 and Django 1.10. -
Vaultier blank page

using GET variables with django
I'm just trying to get a minimum working example of GET variable usage in django. Apologies, I'm very very new to django. At the moment, urls.py looks like: urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^test/', views.engage), ] views.py: def engage(request): return(request.GET) I'm trying to access an integer variable at domain.com/test/&n=10 but at this stage I keep getting Exception Type: AttributeError Exception Value: This QueryDict instance is immutable I've been trying to figure this out for about 2 days now. I've searched pretty widely, but I just don't seem to be getting anywhere. I don't need the answer on a silver platter; links to tutorials etc would be equally appreciated. I feel like there's something pretty core that I'm missing. Thanks. -

However, the migrate command does not create all necessary tables. So, I checked the logs and I realized the following warning; WARNINGS: ?: (mysql.W002) MySQL Strict Mode is not set for database connection 'default' HINT: MySQL's Strict Mode fixes many data integrity problems in MySQL, such as data truncation upon insertion, by escalating warnings into errors. It is strongly recommended you activate it.

Lightweight message queue to use with Celery 4.0
I'm currently using Celery 3.1 in a Django project on Python 2.7. So far, we were using the Django ORM as a broker for development and staging environments. That was convenient, because you could pretty much just check out the sources, install the dependencies, run the migrations and celery worker would just work out of the box. I'm thinking about how to set that up after upgrading to Celery 4.x due to the Django ORM broker having been removed. Are there any message queues that don't require any local setup (or can be pip-installed) and separate launching? -
Do I make the is_superuser accessble to my api in django?
I'm working on a project using django and angular and I need to make some pages accessible only to superusers. I've read somewhere that it isn't advisable to make this available to clients. If so is there any way to make some pages visible only to superusers? I'm new at this so forgive me if the question sound naive. Thank you -
Django: Same code base, same database, but slightly different templates and static files
What method/framework should I use to run multiple websites that share 100% of the code base? The sites should all share a single database, but have slightly different templates, slightly different static files and completely different media files. I am thinking of a method where I can have base templates and base static files that can be overridden with site specific templates/static files. What method can I use to accomplish the task of running multiple sites in this way? Also important: What is a reasonable directory structure? -
Django - Submit multiple forms with one submit button
I'm trying to create a check in page that lists all of the people that have signed up. Each person has an input box that submits the number of hours they were at the event. I want it so that the same form is submitted multiple times for every person; I don't want to have a submit button for every person because there will be several people and it'll be tedious. I'm using a for loop {% for signups in signup %} to loop through the queryset for the people who are signed up. Here's a screenshot to illustrate: In the backend, I want it to save the number of hours to the row in the queryset with the matching name. -

TypeError: 'str' object is not callable in Django 1.10 Admin change_form.html {{ original|truncatewords:"18" }}
I've had this a couple of times and not been able to debug it. Last time I regressed code to my last checkin to avoid it but it remains a mystery. Situation occurs when I use the standard admin app to view/edit my custom objects. I can see the objects listed in the view (in my case http://127.0.0.1:8000/admin/athletes/totalsandstats/ where athletes is my app name, and TotalsAndStats is a model defined within athletes/models.py). When I click on one of the objects to try and view the details, I get the above exception. Django Admin is trying to render the URL http://127.0.0.1:8000/admin/athletes/totalsandstats/2/change/ using the template /usr/local/lib/python3.4/site-packages/django/contrib/admin/templates/admin/change_form.html The error page states that the exception occurred at line 21 in the template, which is this: &rsaquo; {% if add %}{% blocktrans with name=opts.verbose_name %}Add {{ name }}{% endblocktrans %}{% else %}{{ original|truncatewords:"18" }}{% endif %} I see that {{ original|truncatewords:"18" }} is highlighted in red so I assume that "original" is not defined correctly. But I don't know what is the purpose of original, or how it relates to my model. I suspect there must be some mismatch between my model and the way I have defined the corresponding admin model, but I can't … -

Using Django to store session variable, but session variable not appearing in chrome://settings/cookies
I have tried to set session variables with both simply request.session['test'] = id and from django.contrib.sessions.backends.db import SessionStore s = SessionStore() s['test'] = id s.save() Of course I've enabled the appropriate middleware. 'django.contrib.sessions.middleware.SessionMiddleware' I feel I must be setting the session variable correctly because when I print things like print request.session['test'] and print s.session_key I get the output I would expect. What I don't expect to see is that when going to chrome://settings/cookies I don't see the cookies set with the session variables anywhere. Am I misunderstanding how this works? -
