I am trying to build a query set to do a count, the query set involves three models. class Owner(models.Model): name = models.CharField(max_length=10, null=False) class Location(models.Model): name = models.CharField(max_length=10, null=False) owner = models.ForeignKey(Owner, on_delete=models.SET_NULL, null=True, blank=True) class Asset(models.Model): name = models.CharField(max_length=10, null=false) owner = models.ForeignKey(Owner, on_delete=models.SET_NULL, null=True, blank=True) location = models.ForeignKey(Location, on_delete=models.SET_NULL, null=True, blank=True) I am trying to do a

I know that there is plenty of questions like that, I read them all and tried everything, however nothing solved my problem. I'm writing something like blog in Django and of course I want to show pictures to users. Pictures are stored at /static/users/<username>/<image> . My setting.py TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [os.path.join(BASE_DIR, 'templates')] , 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors

I would like to have 'No user assigned' when there is no user to the ticket. I did this to my model but I don't see any changes def __unicode__(self): print 'gets here****' if not self.assigned: return 'No user assigned' else: return self.assigned where assigned is the user assigned for a ticket. IS ther any other way to do this? I have my template and view like this: {% for ticket in tickets %} <tr> <td>{{ ticket.title }}</td> <td> {% for user in ticket.assigned.all %} {{ user.email }}{% if not forloop.last %},{% endif %} {% endfor %} </td> and my View: def get_data(self, **kwargs): context =

In Django Views:- if request.is_ajax(): t = get_template('bar-templates.html') html = t.render(Context({'edit': True, 'user':'some-user' })) return HttpResponse(html) There is two templates: Main template (foo-templates.html) which includes the template (bar-templates.html) . In context edit and user is passed to the bar-templates.html But this variable is also used in foo-templates.html . In django we used to {{ edit }} to catch the variable. Since this variable comes in bar-templates.html . How can I use this to foo-templates.html . foo-templates.html: {% extends "base.html" %} <div class=

When I use ajax to submit a comment form in Django,the page will redirect to a blank page shows me the success data: {"status":"success", "msg":"添加成功"} ,but not stay in current page.I want the page stay in current page and show me the new comment. Here is my update_comment view: def update_comment(request, news_pk): news = get_object_or_404(News, id=news_pk) comment_form = CommentForm(request.POST or None) if request.method == 'POST' and comment_form.is_valid(): if not request.user.is_authenticated: return render(request, 'login.html', {}) comments = comment_form.cleaned_data.get("comment")

I'm thinking a bit about the concept of Django aggregates. I don't quite "get" how they can be used in my case. Basically i have a three-tier hierarchy of objects in my model, and the lowest object (Bar) contain values I want to aggregate. class Bar(models.Model): amount = models.FloatField() class Foo(models.Model): bars = models.ManyToManyField(Bar) class MyUser(models.Model): foos = models.ManyToManyField(Foo) I want my template to do the equivalent of this: {% for user in users %} <h2>{{ user }}</h2> <table> <tr> <td>Foo</td>< <td>Average bar amount</td> </tr> {% for foo in user.foos.all %
