I have used Django2 in python3.7 to develop a web app in windows. I want to show a list of query set in html. view.py: @csrf_exempt def View_by_Course_list(request): print(request.method) if request.method == 'POST': ... query_results_book = Title.objects.filter(id=query_results_book_id).values() print(query_results_book) return render(request, 'list.html', context={'query_results_book': query_results_book}) list.html: {{query_results_book}} <ol> {% for obj in query_results_book %} <li>{{obj.title}} <br> iSBN:{{obj.isbn}} <br> Format issued: {{obj.is_etextbook}}</li> {% endfor %} </ol> The print debug, print(query_results_book) outputs this: <QuerySet [{'id': 4, 'created': datetime.datetime(2020, 6, 25, 10, 15, 41, 856235), 'isbn': 11112, 'is_etextbook': 'Textbook', 'title': 'ACC210 Accounting for Decision Making and Control (customised text), McGraw-Hill'`}]> But in the website page nothing is shown.

SAML2 with Django stuck on infinite loop
I am trying to use the djangosaml2 1.1.0 module in order to implement SSO login. After the successful login, it gets stuck in an infinite loop trying to constantly login again. I have tried to remove the @login_requried decorator, it works on then. But, I need the @login_required decorator in order to prevent not logged in users to access specific views. My believe is that django.contrib.auth.backends.ModelBackend is not properly configured with djangosaml2.backends.Saml2Backend This is my code: settings.py SAML_CONFIG = { # full path to the xmlsec1 binary programm 'xmlsec_binary': '/usr/bin/xmlsec1', # your entity id, usually your subdomain plus the url to the metadata view 'entityid': 'http://localhost:8000/saml2/metadata/', # directory with attribute mapping 'attribute_map_dir': path.join(BASEDIR, 'attribute-maps'), # this block states what services we provide 'service': { # we are just a lonely SP 'sp' : { 'name': 'Federated Django sample SP', 'name_id_format': saml2.saml.NAMEID_FORMAT_PERSISTENT, # For Okta add signed logout requets.

Django Wagtail - How to set the date format?
I have created a Blog with the Django CMS "Wagtail". As a part of a blog page, I want to set a date in a specific format. Now, setting the date itself is not a problem at all. The blog page is constructed a bit like this: date = models.DateField("Post date") intro = models.CharField(max_length=250) body = RichTextField(blank=True) tags = ClusterTaggableManager(through=BlogPageTag, blank=True) author = models.ForeignKey(BlogAuthor, on_delete=models.PROTECT, null=True) ... The DateField then creates a date on my blog page in the format "April 2, 2021". Alas, as we are located in Germany I'd like to change this format to "2. April 2021". I was searching a lot whether it would be feasible to add a parameter to the DateField in order to define the format. Didn't find anything that worked so far. Any ideas? Thanks in advance! Timo -

How to make Django link to different html pages based on the result of a form?
I am confused on how to change html pages based on the results of a form. I want to create a form to get a search query. Based on this query, a page should be rendered to the user. For example, if the page query is chocolate, then a page should be main/chocolate. Same for any other query: main/"query". How is it possible to do this? I have tried using a normal form in order to do this, but this did not work. I have tried: this is from views.py: if request.method == "GET": ask = NewForm(request.GET) if ask.is_valid: Muk = ask.cleaned_data("Stuff") result = util.get_entry(Muk) good = markdown2.markdown(result) return page(request, good) else: return render(request, "encyclopedia/index.html") return render(request, "encyclopedia/layout.html", { "form": ask })``` And it always meets me with an error page, since earlier in views.py, I defined: def page(request, name): ```stuff = util.get_entry(name) if stuff is None: return render(request, "encyclopedia/error.html") things = markdown2.markdown(stuff) return render(request, "encyclopedia/content.html", { "things":things })def page(request, name): stuff = util.get_entry(name) if stuff is None: return render(request, "encyclopedia/error.html") things = markdown2.markdown(stuff) return render(request, "encyclopedia/content.html", { "things":things })``` -
How to count and make addition with for loop with a table in Django?
I created a customer system. In this system, a user has several customers. I have a Customer model and this model has multiple fields like risk_rating, credit_limit, country, etc... I want to list the countries where customers are located and show data about them in a data table. I am using .distinct() method for that, but I cannot figure out how can I show some data. For example, I want to total credit_limit (adding operation) in the related country and I want to count all customers that have Low risk risk_rating. I can do this the long way with if statement. But I can't think of anything other than just creating a concatenated if statement for all countries. This would be a very long and inefficient way. Because there are 208 countries in the world. How can I do that? Note: I try to use for loop counter for counting the number of risks but it did not work properly. models.py class Customer(models.Model): RISK_RATING = [ ('Low Risk', 'Low Risk'), ('Medium Risk', 'Medium Risk'), ('Moderately High Risk', 'Moderately High Risk'), ... ] customer_name = models.CharField(max_length=100) country = models.ForeignKey(Country, on_delete=models.CASCADE, null=True, unique=False) credit_limit = models.FloatField(default=0, null=True) risk_rating = models.CharField(max_length=50, default='Select', choices=RISK_RATING, … -
Django suddenly gives me error that Apps aren't loaded yet
I am using Django3.1. All was working fine. I pip installed a new app and tried to run makemigrations. It suddenly doesn't work anymore. I get error 'Apps are not loaded yet'. I thought it was the app. Uninstalled it. Didn't work. Deleted the virtualenv directory. Created new one and installed all apps again except the last one. It didn't work. I had installed another version of Postgres and hadn't restarted my computer since then. Restarted but didn't work. Tested by running another project to make sure it was not new Postgres issue. That worked as expected. Commented out my url confs and installed apps in the settings.py. But still the same error. Tried multiple SO suggestion related to this error but nothing works. Can anyone please help.
