Displaying an image from string in django template
To give you an idea of my starting point: I have a set of forms with a label and checkbox. Some of my labels are supposed to display pictures, but not all. The pictures when they should be displayed are never at the same place with regards to the label text (ie sometimes the picture should be displayed in the middle of the label, sometimes at the beginning, end...). So the only way I could think of to address this problem was to have in my label at some place, something like <img src="{{ MEDIA_URL }}/sources/1/2.jpg" height=300px/> within the text. The problem is that it is considered as a string and not as an html tag. Would you have any idea of to address this issue? I'm currently run out of ideas. Thank you very much. Soso :) -

Django - Is there an easier way to to display movie genre pages using DRY
Ive created a movie website using Django 2.1, i have a few pages for genres Admin-top,Latest,Thriller,Horror,Action etc... which is fine, but i have another 10+ genres and 10+ years to do and am thinking there must be a better way, the DRY way, then to have the individual pages when the page layout is the same etc, its just the content which changes like in my detail view.. i have google,searched etc i cant seem to figure it out. Any help is appreciated Here is my views from django.shortcuts import render, get_object_or_404 from .models import Movie, Banner from django.views.generic import ListView, DetailView # Base page for pages. def base(request): return render(request, 'movies/base.html') # HOME-PAGE class HomeListView(ListView): model = Movie template_name = 'movies/home.html' # <app>/<model>_<viewtype>.html def get_context_data(self, **kwargs): context = super(HomeListView, self).get_context_data(**kwargs) context['admin_movies'] = Movie.objects.filter(admin_top__contains='Yes').order_by('-date_posted') context['latest_movies'] = Movie.objects.all().order_by('-date_posted') context['thriller_movies'] = Movie.objects.filter(genre__contains='Thriller').order_by('-date_posted') context['horror_movies'] = Movie.objects.filter(genre__contains='Horror').order_by('-date_posted') context['action_movies'] = Movie.objects.filter(genre__contains='Action').order_by('-date_posted') # Add any other variables to the context here return context # MOVIE DETAIL PAGE class MovieDetailView(DetailView): model = Movie queryset = Movie.objects.all() template_name = 'movies/movie-detail.html' def get_object(self): title_ = self.kwargs.get('title') return get_object_or_404(Movie, title=title_) # ADMIN MOVIE-PAGE class AdminListView(ListView): model = Movie queryset = Movie.objects.filter(admin_top__contains='Yes') template_name = 'movies/admin-top.html' context_object_name = 'admin_movies' ordering = ['-date_posted'] … -
django __class__ method not working on m2m relationship
In my django project at a instance I need class name of object by its reverse relationship, for that I used __class__ method . This is working fine with OneToOne relationship that is print(instance.content_object.__class__) and output is - <class 'products.models.ProductCreateModel'> but when using it with m2m it gives me print(instance.product_seller.__class__) and output is - <class 'django.db.models.fields.related_descriptors.create_reverse_many_to_one_manager.<locals>.RelatedManager'> How can I get the class name ? -
Default Time with MM:SS format - Django
I have written code for countdown timer using Javascript and to make it dynamic I have given an option for admin to change the time accordingly.

Is there any datatype or a way to resolve the time format. My application need timer in MM:SS and doesn't need hours. model.py class PhysicalPostPage(AbstractForm): intro = RichTextField(blank=True) strength = RichTextField(blank=True) agility = RichTextField(blank=True) flexibility = RichTextField(blank=True) points_for_this_activity = models.IntegerField(blank=True, default=0) timer_for_this_activity = models.TimeField(blank=True, default=datetime.time(00, 11)) thank_you_text = RichTextField(blank=True) For testing purpose, I have set the timer to 11 seconds. javascript function doCount(){ var timer2 = "{{ page.timer_for_this_activity|safe }}"; var interval = setInterval(function() { var timer = timer2.split(':'); //by parsing integer, I avoid all extra string processing var minutes = parseInt(timer[0], 10); var seconds = parseInt(timer[1], 10); --seconds; minutes = (seconds < 0) ? --minutes : minutes; seconds = (seconds < 0) ? 59 : seconds; seconds = (seconds < 10) ? '0' + seconds : seconds; //minutes = …
