Persistence issues with checkboxes
My Goal Is to create a shopping webpage where users can filter through the product selection by checking checkboxes. Instead of having a "submit" button I wanted the page to submit as soon as the user checked the checkbox. Example: the "refine by" section on Amazon. My Solution The best way would have been to use AJAX however I opted for a simple javascript / jquery function instead: $(":checkbox").change(function () { $('#product-filters').submit() }); Clicking the checkbox would correctly refresh page and apply filters, however the checkbox would appear un-checked to the user. So in Django I implemented following workaround: filters = request.GET.getlist('filters', None) selected_filters = [] try: for f in filters: selected_filters.append(int(f)) except TypeError: selected_filters = None return { # ..... 'selected_filters': selected_filters, } And then in my template: <input {% if filter.id in selected_filters %}checked="checked"{% endif %} ... all my other attrs></input> My Issue While all of the above works correctly I now have the issue that if a user clicks on a checked checkbox in order to uncheck it, it will simply refresh the page and keep it checked, with that filter applied. How should I go about fixing this? -
Converting a table from html file to pdf using xhtml2pdf
Hi guys I am having a problem using xhtml2pdf. I am following a tutorial and it worked (note: the data in the tutorial is hardcoded). So I change a bit of the code from the tutorial so I can fetch data from a database using django-rest-framework. When I run the project there were no errors but I typed the url to see my pdf file, its error 404. here is my views.py class GeneratePdf(ReadOnlyModelViewSet): queryset = DirectoryTb.objects.all() serializer_class = DirectoryTbSerializer def get(self, request, queryset, *args, **kwargs): pdf = render_to_pdf('directory.html', queryset) return HttpResponse(pdf, content_type='application/pdf') here is my urls.py router = DefaultRouter() router.register(r'^pdf', GeneratePdf) urlpatterns = router.urls -
Vue.js in Django Templates
I am trying to use Vue.js in Django templates. One such template is the following: {% load static %} <!DOCTYPE html> <html> <head> </head> <body> <div id="myApp"> <span>Hello [[ message ]]</span> <div id="map"></map> </div> <script src="https://code.jquery.com/jquery-2.2.4.min.js" integrity="sha256-BbhdlvQf/xTY9gja0Dq3HiwQF8LaCRTXxZKRutelT44=" crossorigin="anonymous"></script> <script src="https://v1.vuejs.org/js/vue.js"></script> <script src="{% static 'js/script.js' %}"></script> <script async defer src="https://maps.googleapis.com/maps/api/js?key=AIzaSyC62HW0L7DIhL7oLbWvCEekHOkPWdxBPwk&callback=initMap"></script> </body> </html> I changed Vue's interpolation delimiters to [[ ]] to avoid conflict with Django. My script.js looks as follows: $(function() { var app = new Vue({ el: '#myApp', delimiters: ['[[', ']]'], data: { message: 'Hello, world!' } }); }); Unfortunately, the HTML rendered contains [[ message ]]. Has anyone else faced a similar issue? -

Include keyword in url.py not working without app_name(Django 2.0)
When I try to use the include keyword in url.py to reverse match url in model.py reverse("products:detail", kwargs={"slug": self.slug} it says: Specifying a namespace in include() without providing an app_name ' django.core.exceptions.ImproperlyConfigured: Specifying a namespace in include() without providing an app_name is not supported. Set the app_name attribute in the included module, or pass a 2-tuple containing the list of patterns and app_name instead. I see that in Django 2.0, you have to provide app_name with namespace.

Django 2.0 url() to path()
I am currently learning Django. Until now I was working with Django 1.1 but now I am working with Django 2.0. Django 2.0 uses path() instead of url() and I don't quiet understand that. In Django 1.1 my urls looked like this: url(r'^about/$', views.AboutView.as_view(), name='about'), Now with Django 2 it looks like this path('about/', views.AboutView.as_view(), name='about'), So far so good but I just don't undertand how I can convert this url(r'^post/(?P<pk>\d+)$', views.PostDetailView.as_view(), name='post_detail'), So that it works with the new version. Just chagning url to path doesn't work, and changing url to re_path doesn't work either. Can someone help me with that Problem? Thanks in advance -

able to check db connection host or name (not db name but the setting) ? django
I am not trying to check the db name to the connection, I have multiple database setup in django and also used the database route to create a failover but I am wondering if I can get the name of the connection host or the name given to the settings... for example DATABASES = { 'default': { # get this name 'ENGINE': 'django.db.backends.mysql', 'NAME': 'db_name', 'USER': 'euser', 'PASSWORD': 'password', 'HOST': 'host', # get this host name 'PORT': 3306, }, } Is it possible to get those names I commented out above? For my failover, I am trying to send an email if another db is being used, but it would be great if I can get especially the host so it would be easier on me P.S. off topic, is it possible to change the name default to other names? I tried changing it and I would get errors. Seems like I must have at least one database setting name called default Thanks in advance for any help. -
auth_views LoginView does not show inactive user error message
I'm using Django 1.11 and the simple auth_views.LoginView - buildin form for my users to login. Login etc works fine except if the user is inactive it shows: Please enter a correct username and password. Note that both fields may be case-sensitive. even tho that's not the right error. Relevant code: urls.py from django.contrib.auth.views import LoginView app_name = 'accounts' urlpatterns=[ url(r'^login/$',auth_views.login,{'template_name': 'accounts/login.html'},name='login')] login.html <div class="container front_container"> <div class="jumbotron"> <form enctype="multipart/form-data" method="POST"> {% csrf_token %} {% bootstrap_form form %} {% buttons %} <button type="submit" class="btn btn-primary">Submit</button> {% endbuttons %} </form> </div> I've read in a different thread that this might be an issue with the django backend recognizing the error, but not outputting it. But I don't know what I need to do to fix it. I've also seen this error been put out in other website using the same LoginView. Does that mean it's a matter of the django version I'm using or a another variable I can't think of? Cheers -
Django: view-less template refreshed through AJAX?
So I'm refreshing an HTML div with some data on background asynchronous jobs. I obviously want to keep this as DRY as possible so I want to generate the HTML server-side and only have the Javascript code call it whenever the socket gets a message from the server. I don't want to have to call a view for each time this template needs re-rendering, it seems very resource-heavy. How can I do it?

I am new to django and I am getting confused over that, basically I want to iterate through all of the series and return the ones that are in certain genre. models.py class Series(models.Model): series_title = models.CharField(max_length=50) series_desc = models.TextField(max_length=500) series_date_published = models.DateTimeField() class Genres(models.Model): genre_name = models.CharField(max_length=50) genre_serie = models.ManyToManyField(Series) class Episodes(models.Model): episode_title = models.CharField(max_length=50) episode_desc = models.TextField(max_length=500) episode_date_published = models.DateTimeField() episode_number = models.IntegerField() episode_series = models.ForeignKey(Series, on_delete=models.CASCADE) views.py class IndexView(generic.ListView): model = Series template_name = 'videos/index.html' context_object_name = 'series' def get_queryset(self): return Series.objects.all() class ViewSeries(generic.ListView): model = Episodes template_name = 'videos/videos.html' context_object_name = 'episodes' def get_queryset(self): return Episodes.objects.filter(episode_series=self.kwargs['pk']) class ViewGenres(generic.ListView): model = Series template_name = 'videos/genres.html' context_object_name = 'series' def get_queryset(self): return Series.objects.filter(genres__genre_serie=self.kwargs['pk']) And I am trying that to display my series in a genre: {% for s in series %} <a href='(% url ?? %)'>{{ s.series_title }}</a></td> {% endfor %} urls.py app_namme = 'videos' urlpatterns = [ path('', IndexView.as_view(),name='index'), path('viewseries/<int:pk>', ViewSeries.as_view(),name='detail'), path('viewgenres/<int:pk>', ViewGenres.as_view(),name='genres'), ] I placed that url because from there I want to get the link to the series but when I type {% url 'detail' ser.id %} I got NoReverseMatch error. I am pretty sure that there is an easy solution to all of that … -
Is this a good case to deviate from Django's ORM and use raw SQL? (Unless models can be dynamically generated)
So I have been using Django's ORM for everything; however, I have gotten to a part of this application where I don't think it makes sense. That is unless, models can be dynamically generated and dropped into models.py so I don't have to update it every year. The company this application is for aggregates data from various industries. There is no overlap between them. Furthermore, the data collected from each industry can vary from year-to-year. Thus tables are broken up like: Industry_A_15 Industry_A_16 Industry_A_17 Industry_B_15 Industry_B_16 Industry_B_17 I don't see how the ORM could work unless I added them to models.py every year (there are over a hundred columns for each). The most efficient way, I can think of, for doing it would be to do something like ./manage.py inspectdb > models.py, but that tends to not work on tables with constraints. So would this be a good case to write in raw SQL? It sounds like I'd want to avoid the model layer altogether really: https://docs.djangoproject.com/en/2.0/topics/db/sql/#executing-custom-sql-directly Then I could dynamically refer to the tables and really not have to touch it in the future. Also, the queries would be pretty basic SELECT such that I would think it should … -
Is there any way to create an array of files in a model in django?
I am creating a web app for cloud storage where user can create folders and upload files. I want to create a model for files like: class upload(models.Model): files = # array of files which I don't know how to create title = models.CharField(max_length = 30) user = models.ForeignKey(User,on_delete=models.CASCADE) I will be thankful if anyone suggests me how to do so or tell me any other efficient way to upload files and use it. -
