问题 Quick question - I'm not sure what would be the correct way to handle this. Essentially I wish to define a custom tag which handles some logic then returns all posts of model Post which has the is_featured field set to True. I have tried a number of avenues to get this working, but none have worked. My last coherant "guess" was the following: templatetags/blog_tags.py: @register.inclusion_tag('blog/post/featured_posts.html') def show_featured_posts(count=4): """Return 4 of the most recent

问题 If I not complete the form for "annoinizio" or "annofine" or "stagioni" or "totepisodi" django plays form.is_valid() and returns False. How can I save the data even if their value is null? Models: class Tvserie(models.Model): titolo = models.CharField(max_length = 100) titolo_originale = models.CharField(max_length = 200) annoinizio = models.IntegerField(null=True, blank=True) annofine = models.IntegerField(null=True, blank=True) stagioni = models.IntegerField(null=True, blank=True)

问题 I've been following this tutorial: https://www.youtube.com/watch?v=jKSNciGr8kY I am just completely stuck, I have gone through my code line by line and still cannot figure out what is wrong.

Heres the view for it: def search(request): if request.method == 'POST': search_text = request.POST['search_text'] else: search_text = '' if search_text: documents = Document.objects

Anything I have referenced to be called from the static files (./manage.py collectstatic) is not showing where referenced in the html. I have it imported in my views: from django.shortcuts import render, render_to_response from django.http import HttpResponse, HttpResponseRedirect from django.contrib.auth.forms import UserCreationForm from django.template import loader from django.contrib.auth.decorators import

问题 Django urlize docs say: The urlize filter also takes an optional parameter autoescape . If autoescape is True , the link text and URLs will be escaped using Django's built-in escape filter. The default value for autoescape is True . I'd like to use this parameter, but the documentation says nothing about how to actually pass a keyword argument to a template filter. Is it possible, and if so, how do I do that? 回答1: Apparently urlize gets that keyword argument from current autoescape settings,

问题 When I bring up 127.0.0.1:8000, the current page that show up is something.html template. I would need to make it appear index.html at first launch, then when I click on other parts,it should go to 127.0.0.1:8000/something.html (or 127.0.0.1:8000/myapp/something.html). What would be the structure to achieve this? I frequently get error message : The current URL didn't match any of these. Currently, my structure is project ---myapp ---admin.py ---models.py ---url.py ---views.py ---static --
