问题 My goal is to write dynamically some urls of images in the HTML page. Urls are stored in a database. To do so, first I am trying to render a simple varable in a template.

I am using a very simple JS library, which will allow the sorting: page.html {% if Variable %} <table class

问题 i am learning django from official django tutorial. and i am getting this error when vote something from form. this caused from - probably - vote function under views.py here is my views.py / vote function : def vote(request,poll_id): p=get_object_or_404(Poll, pk=poll_id) try: selected_choice = p.choice_set.get(pk=request.POST['choice']) except (KeyError, Choice.DoesNotExist): return render_to_response('polls/detail.html', {'poll':p, 'error_message' : "didint select anything ",}, context

问题 I'm trying to understand if it it's possible to incorporate dynamic data into a Django Chart JS architecture. I went through a couple of tutorials and ultimately got Django to work with ChartJS and it's very good when I'm able to hard code values and then display the related graphs. What I'm ultimately trying to do is this same exercise with dynamic data from my database. I found this identical question in SO, https://stackoverflow.com/questions/47575896/dynamic-chart-using-django-and-chart
