HTMLCalendar displaying as a String instead of using the HTML properly (Django)
I'm trying to display an HTMLCalendar in my django project but it's only displaying the html code instead of the actual Calendar. views.py def CalendarView(request): cal = HTMLCalendar().formatmonth(2020, 10, withyear=True).replace('<td ', '<td width="150" height="150"') return render(request, 'calendar.html', {'cal': cal}) calendar.html {% extends 'base.html' %} {% block tilte %} Home {% endblock %} {% block body %} <div id="content-main"> <ul class="object-tools"> <li> <a href={{ previous_month }}> Previous month </a> </li> <li> <a href={{ next_month }}> Next month </a> </li> </ul> {{ cal }} {% endblock %} This is what gets displayed instead of the actual calendar -
Checkmark in Django, getting which one is checked
I'm new in django and trying to set a form like this: my form So far I did this: result.html: .... <form id="form" name="form" method="GET"> <p> <label class="container">Yes <input type="checkbox" name="1"> <span class="checkmark"></span> </label> <br> <label class="container">No <input type="checkbox" name="0"> <span class="checkmark"></span> </label> <br> <label class="container">No proper image <input type="checkbox" name="2"> <span class="checkmark"></span> </label> <br> </p> .... in views.py: def result(request): .... if request.method == 'GET': context = {} context['form'] = FormYesOrNo() .... return render(request, template_name, response1) in forms.py: choices = [(1, 'Yes'), (0, 'No'), (2, 'none')] class FormYesOrNo(forms.Form): def PrdJudgeRe(self): PrdJudge = forms.TypedChoiceField( choices=choices, coerce=str) return (PrdJudge) Now in views.py I do not know how to get the checked box index or value. when running server and for example I check yes in the log I see this: "GET /result/?1=on HTTP/1.1" 200 1389 which means that it can see 1 is on but how can I get that? -
How to import 2 or more js files into jinja2
I know that to import a js file, I can simply do: <script src="/static/js/example.js"> But i need to import two or more files js into my jinja file.

Choosing the right datetimepicker
I am having a tough time finding a datetimepicker that does exactly what I need and works with Bootstrap 4, Django, and Django Crispy Forms. The critical thing I need is the ability for the user to type what they want in the date input field without the calendar popping up with an icon next to the input field upon which they can click if they would like to choose a date visually. I have had problems with a few datetimepickers with no responses on this platform as to how I might resolve those issues. I first tried the Django wrapper for Tempus Dominus (django tempus dominus) which seemed the most logical choice, but it does not play well if you are using Django Crispy Forms layouts to render the forms. When the input is converted to a datetimepicker widget with a clickable calendar icon, the layout is thrown off as the input field's container gains extra height without any detectable CSS margins, padding, etc. It also forces the field to be required when it should not. Also, if the server side validation returns an error, the error text is disabled (changes css of the text element to display:none) although … -
I can't save changes to entry after clicking 'edit entry' button in Django
I have a problem with editing entry in Django. After changing the text it can't be saved and get redirected to Entries page.

'Slide' object has no attribute 'topicdetail_set'
I created a model for Slide on django. below is model.py class Slide(models.Model): user = models.ForeignKey(User, on_delete=models.DO_NOTHING, blank=True) text = models.CharField(max_length=300) is_deleted = models.BooleanField(default=False) topic_id = models.ForeignKey(Article, on_delete=models.DO_NOTHING) created_at = models.DateTimeField("created at", auto_now_add=True) objects = models.Manager() def __str__(self): return self.text serializer.py class SlideSerializer(serializers.ModelSerializer): topicdetail_set = ArticleDetailSerial(many=True) user_detail = FindOwnerSerializer(source='user', read_only=True) author = AuthorSerializer(many=True) class Meta: model = Slide fields = ('id','text', 'created_at', 'topicdetail_set', 'user_detail','author') When I run the url for slide http://127.0.0.1:8000/article/slide/ then I got below error AttributeError: Got AttributeError when attempting to get a value for field `topicdetail_set` on serializer `SlideSerializer`. The serializer field might be named incorrectly and not match any attribute or key on the `Slide` instance. Original exception text was: 'Slide' object has no attribute 'topicdetail_set'. Now I am confused, Is the code that I have created is wrong? And if it is wrong then how should I fix it? -
How to share Python method between two Django classes?
I have two classes in my Django models.py file: class ProfileManager(models.Manager): def create_profile(self, user, member): # Set default age to 100 years old when profile is created. years_ago100 = datetime.datetime.now() - datetime.timedelta(days=101 * 365) age = calculate_age(years_ago100) # <- Used here profile = self.create(user=user, person_dob=years_ago100, person_age=age) return class Profile(models.Model): person_dob = models.DateField() person_age = models.IntegerField() objects = ProfileManager() def save(self, *args, **kwargs): # Update to real age when user edits profile for the first time. self.person_age = calculate_age(self.person_dob) # <- Used here too super(Profile, self).save(*args, **kwargs) Each class uses this calculate_age method: def calculate_age(born): today = datetime.date.today() return (today.year - born.year - ((today.month, today.day) < (born.month, born.day))) How can I make this method accessible to both classes? One easy way would be to make the method global like this but that seems like a kludgy way to do it: def calculate_age(born): ... class ProfileManager(models.Manager): ... class Profile(models.Model): ... Also, this wouldn't work if I wanted to access that method outside of this particular models module. Is there a standard way to do this when using Django? -
If AtomicRequest is True in Django Is there a way to do a manual commit?

Anaconda worker could not start because:
I've just installed Anaconda by using Package Control; and, after installing it, the terminal show me this message: anacondaST3: ERROR - Anaconda worker could not start because: connection to localhost:50462 timed out after 0.2s. tried to connect 7 times during 2.0 seconds check that there is Python process executing the anaconda jsonserver.py script running in your system. If there is, check that you can connect to your localhost writing the following script in your Sublime Text 3 console: import socket; socket.socket(socket.AF_INET, socket.SOCK_STREAM).connect(("localhost", 50462)) If anaconda works just fine after you received this error and the command above worked you can make anaconda to do not show you this error anymore setting the 'swallow_startup_errors' to 'true' in your configuration file. And, the Anaconda autocompletation just doesn't work, the only reason I installed Anaconda for. What should I do? I'm practically a beginner in all of this programming stuff, so, be nice:( -

How to resolve NoReverseMatch in django while using reverse with id as argument?
So I've been getting the NoReverseMatch presumably from having passing id value greater than 9. So here's the error message I'm getting : Reverse for 'article-details' with arguments '('2', '9')' not found. 1 pattern(s) tried: ['a/(?P<pk>[0-9]+)$'] here's my code: Models.py class Post( models.Model): title = models.CharField( max_length = 250 ) author = models.ForeignKey( User , on_delete=models.CASCADE ) body = models.TextField() def get_absolute_url(self): print((self.id)) return reverse('article-details' , args= str(self.id)) urls.py urlpatterns = [ path ( 'a/<int:pk>' , ArticleDetailView.as_view() , name='article-details' ) , path('create/' , CreatePost2.as_view() , name='create_post' ) , path ( 'p/<int:pk>' , postDetails , name= 'post-details' ) , ] I think that since i have upward of 10 entries in database whenever reverse is called with id > 9 it interprets it as touple with 2 values. How do i solve this issue ? -
Link added to HTML by JavaScript does nothing when clicked
I'm creating a primitive search engine for the support database on my Django site. I have JavaScript set to listen for any changes to the search field, and then query for suggestions to the server. The script then loops through the JSON result and generate a Bootstrap-styled dropdown below the search box. Everything about it is working flawlessly… except the part where clicking the suggestions actually takes you there. Hovering over the links turns them blue and shows their target in the lower-left corner of my Chromium Edge. But clicking just does nothing. You can inspect the HTML and click the link's target there, and it works. You can even delete the element and recode it back in the inspector and clicking it works there! It must have something to do with JavaScript adding it and not refreshing properly. Here's part of my HTML (a lot of the extra mumbo-jumbo is for Bootstrap; I copied it right from their documentation): <input type="text" class="form-control" placeholder="Search" id="query"> <div class="input-group-append"> <button type="button" class="btn btn-outline-primary dropdown-toggle dropdown-toggle-split" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false"> </button> <div class="dropdown-menu dropdown-menu-lg-right" id="suggestions"> <p class="p-4 text-muted" id="noresults"> No articles that mach your query were found.

Post class does not have objects variable in Django for Beginners
In W S Vincent's "Django for Beginners," on page 71 he creates a simple message board Django project and then creates some testing code. His simple Post class is from django.db import models class Post(models.Model): text = models.TextField() def __str__(self): return self.text[:50] and then he creates a tests.py class with the following code: from django.test import TestCase from django.urls import reverse #new from .models import Post class PostModelTest(TestCase): def setup(self): Post.objects.create(text='just a test') def test_text_content(self): post = Post.objects.get(id=1) expected_object_name = f'{post.text}' self.assertEqual(expected_object_name, 'just a test') However, as you can see, there is no Posts.objects variable or method, and the test fails. I don't see what he intended to do here, but those with more Django experience may be able to point out what is wrong. -
