Diplay object list, not working - django

I guess that I will ask a very simple question, but it is a sign that I still do not get something.
I have a team model and I would like to display a list of all the team that the logged in user created.
I tried with
{% extends 'base.html' %}
{% block body %}
<div class="container">
<div class="jumbotron">
<h2>Select one of your team and link it to your project</h2>
</div>
<div class="col-md-8 col-md-offset-2">
{% for i in team_set.all %}
<p>{{ i.team_name }}</p>
{% endfor %}
</div>
</div>
{% endblock %}
But first it does not display anything and it is suppose to show all the team and not only the teams that the current logged in user created.
COuld you please give me a hand ?
model.py :
class Team(models.Model):
team_name = models.CharField(max_length=100, default = '')
team_hr_admin = models.ForeignKey(MyUser, blank=True, null=True)
members = models.ManyToManyField(MyUser, related_name="members")
def __str__(self):
return self.team_name
view.py:
class LinkTeam(TemplateView):
template_name= 'link_project.html'
url.py:
from django.conf.urls import url, include
from website import views
app_name = 'website'
urlpatterns = [
url(r'^hr_index/$', views.HRIndex.as_view(), name='hr_index'),
url(r'^addproject/$', views.ProjectCreate.as_view(), name='add_project'),
url(r'^addteam/$', views.TeamCreate.as_view(), name='add_team'),
url(r'^linkteam/$', views.LinkTeam.as_view(), name='Link_team'),
url(r'^project/(?P<pk>[0-9]+)/$',views.ProjectDetailView.as_view(), name='ProjectDetails'),
]

Simply, you can try this
in the View
class LinkTeam(TemplateView):
template_name= 'link_project.html'
def get(request):
courts = Yourmodel.objects.all() # worth looking into?
return render_to_response(self.template_name, {'courts': courts})
AND in HTML:
<div class="col-md-8 col-md-offset-2">
{% for i in courts %}
<p>{{ i.team_name }}</p>
{% endfor %}
</div>

Django Display count of database entries related via foreign key

I have two models, ProjectNotes and ProjectNoteComments. ProjectNoteComments are related to ProjectNotes via a foreign key. I want to display the number of comments each note has on a listview. I am just learning Django and so far I have not been able to figure out how to retrieve and display the comment count.
My view:
(I do import count)
class ProjectNotesList(ListView):
model = ProjectNotes
template_name = 'company_accounts/project_notes.html'
comments = ProjectNotes.comments
def related_project(self, **kwargs):
project = get_object_or_404(Project, id=self.kwargs.get('pk'))
notes = ProjectNotes.objects.all
return notes
def get_context_data(self, **kwargs):
# Call the base implementation first to get a context
context = super().get_context_data(**kwargs)
context['project'] = get_object_or_404(Project, id=self.kwargs.get('pk'))
return context
commentscount = ProjectNotes.objects.annotate(num_comments=Count('comments'))
My template:
{% extends 'base.html' %}
{% block content %}
<div class="section-container container">
<h1>Notes for {{ project }}</h1>
{% if project.notes.all %}
{% for note in project.notes.all %}
<div class ="projectnotes-entry">
<div class="col-sm-8">
<div class="row-sm-6">
<div class="card mb-2">
<div class="card-body">
<div class="card-title">{{ note.title }}</div>
<div class="card-text">{{ note.body | safe | truncatewords:"20"|linebreaks }}
read more</div>
</div>
</div>
</div>
</div>
</div>
<h2>comments count</h2>
{{ commentscount }}
{% endfor %}
{% else %}
<p>No notes have been have been added yet.</p>
{% endif %}
</div>
{% endblock content %}
The models:
class ProjectNotes(models.Model):
title = models.CharField(max_length=200)
body = tinymce_models.HTMLField()
date = models.DateField(auto_now_add=True)
project = models.ForeignKey(Project, default=0, blank=True, on_delete=models.CASCADE, related_name='notes')
def __str__(self):
return self.title
class ProjectNoteComments(models.Model):
body = tinymce_models.HTMLField()
date = models.DateField(auto_now_add=True)
projectnote = models.ForeignKey(ProjectNotes, default=0, blank=True, on_delete=models.CASCADE, related_name='comments')
Short version:
{{ note.comments.all.count }} # possibly works also without 'all' but can't check right now
I've just answered similar problem with simple explanation of relationships.

How can I include a template inside another template?

Im new to programming and I looking if there is there a way that I can include a template inside other template. Im working on a project that I want to display on the same page a content of a certain topic and flashcards to test my knowledge of this topic, and Im stuck when trying to display my cards on the same page (I could only make it work using another url). Here is what I have so far:
models.py:

Is there a way to see deckView inside topic_detail.html? Sorry if I didn't made myself clear.
Update:
I tried inserting {% include 'viewDeck.html' %} as passing the context deck_obj, card_list and card_obj to topic_detail.html, but it gives me this error: NameError: name 'deck_id' is not defined. How can I fix this?
Thank you.
Did you build the url correctly ?
To be able to pass the deck_id like you did in your view, you have to tell your url that you want to pass some data in, by writing something like this in your urls.py :
from name_of_your_app import views
url(r'deck/(?P<deck_id>\d+)/$', views.viewDeck , name='name_of_you_url'),
(?P<deck_id>\d+) is the important part, as it indicates that you will receive a numerical data which can be called with the name "deck_id".

How can I grab articles with the same tag, so within a template I can display those articles?

I'm new to Django, so thanks for any help.
I have an Article model, and I would like to display related/similar articles by assigning tags to each article.
I've tried making a function/filter in my views.py that inherits from self (that particular article) and filters out the articles with the same tag, but with no success.
from django.db import models
class Article(models.Model):
title = models.CharField(max_length=200, blank=True)
thumbnail = models.ImageField(max_length=200, blank=True)
tag = models.CharField(max_length=200, blank=True)
from .models import Article
class ArticleView(DetailView):
template_name = "article/article.html"
model = Article
def related_articles(self):
tagged = Article.objects.filter(tag=self.tag)
return tagged
{% if articles.objects.all %}
{% for article in article.objects.all|related_articles %}
<div>
<img src="{{ article.thumbnail.url }}">
<span>{{ article.title }}</span>
</div>
{% endfor %}
{% endif %}
So, whenever I try to use this filter I get no results.
I think the related_articles function should be on the model class.
from django.db import models
class Article(models.Model):
title = models.CharField(max_length=200, blank=True)
thumbnail = models.ImageField(max_length=200, blank=True)
tag = models.CharField(max_length=200, blank=True)
def related_articles(self):
tagged = Article.objects.filter(tag=self.tag).exclude(pk=self.pk)
Suppose your have a view like this:
def articles(request):
articles = Articles.objects.all()
context = dict(articles=articles)
return render(request, 'app/articles.html', context)
You could have a template like this:
{% if articles|length %}
{% for article in articles %}
<div>
<img src="{{ article.thumbnail.url }}">
<span>{{ article.title }}</span>
{% for related_article in article.related_articles %}
<span>{{ related_article.title }}</span>
{% endfor %}
</div>
{% endfor %}
{% endif %}

Django unit test will not update BooleanField

I have a situation where I want to have published functionality for articles, and I have it. The problem is that I can't get my unit test to work properly, trying to post True to the published field.
Here's what my tests look like.
class ArticleDetailViewTest(TestCase):
def setUp(self):
email = 'testuser#gmail.com'
first_name = 'test'
last_name = 'user'
password = 'test15146'
user = User.objects.create_user(email, first_name, last_name, password)
self.client = Client()
self.client.login(username='testuser#gmail.com', password='test15146')
def test_can_publish_article_from_POST(self):
other_article_two = Article.objects.create(name='Test Name One', author=User.objects.get(email='testuser#gmail.com'))
correct_article_two = Article.objects.create(name='Test Name Two', author=User.objects.get(email='testuser#gmail.com'))
response = self.client.post(reverse('publish_article', kwargs={'pk' : correct_article_two.pk}))
self.assertEqual(response.status_code, 302)
self.assertRedirects(response, f'/articles/{correct_article_two.pk}/')
self.assertEqual(correct_article_two.published, True)
Here's what my publish article view looks like.
def publish_article(request, pk):
article = get_object_or_404(models.Article, pk=pk)
if request.method == "POST":
article.published = True
article.save(update_fields=['published'])
return redirect('article_detail_view', pk=article.pk)
else:
raise Http404
Here are my urls.
from django.urls import path
from . import views
urlpatterns = [
path('', views.HomePageView.as_view(), name='home'),
path('new/', views.ArticleCreateView.as_view(), name='article_new'),
path('<int:pk>/', views.ArticleDetailView.as_view(), name='article_detail_view'),
path('<int:pk>/publish/', views.publish_article, name='publish_article'),
path('<int:pk>/unpublish/', views.unpublish_article, name='unpublish_article'),]
Here are my models.
from django.conf import settings
from django.db import models
from django.urls import reverse
from django import forms
class Article(models.Model):
name = models.CharField(max_length=255, blank=False)
author = models.ForeignKey(
settings.AUTH_USER_MODEL,
on_delete=models.CASCADE,
)
published = models.BooleanField(default=False)
def __str__(self):
return self.name
def get_absolute_url(self):
return reverse('article_detail_view', args=[str(self.id)])
class ArticleForm(forms.ModelForm):
class Meta:
model = Article
fields = ['name',]
Lastly, here is the template.
{% extends 'base.html' %}
{% block title %}{{ article.name }}{% endblock %}
{% block content %}
{% if article.author_id == user.pk %}
<div class="row">
<div class="col-6 col-centered">
<h2 class="text-center">{{ article.name }}</h2>
<p class="text-center">by {{ article.author.first_name }} {{ article.author.last_name }}</p>
{% if article.published %}
<small class="form-text text-muted mb-1">This article is public.</small>
<form method="post" action="/articles/{{ article.pk }}/unpublish/">
{% csrf_token %}
<input type="submit" name="unpublish" value="Unpublish Article" id="id_unpublish_button" class="btn btn-primary btn-md"/>
</form>
{% else %}
<small class="form-text text-muted mb-1">This article is private.</small>
<form method="post" action="/articles/{{ article.pk }}/publish/">
{% csrf_token %}
<input type="submit" name="publish" value="Publish Article" id="id_publish_button" class="btn btn-primary btn-md"/>

{% endif %}
</div>
</div>
{% elif article.published %}
<div class="row">
<div class="col-6 col-centered">
<h2 class="text-center">{{ article.name }}</h2>
<p class="text-center">by {{ article.author.first_name }} {{ article.author.last_name }}</p>
</div>
</div>
{% else %}
<div class="row">
<div class="col-6 col-centered">
<p class="text-center">This article is private.</p>
</div>
</div>
{% endif %}
{% endblock %}
This is the error message I'm getting from my test. The issue seems to be I can post to the URL with self.client.post . Any help would be greatly appreciated.

For loop for ManytoMany Field Type

How should I create a for loop in my template so that I can show a ManyToMany relationship?
Given that:
in models.py I have
class Cycle(models.Model):
cycle_name = models.CharField(max_length=150)
cycle_description = models.CharField(max_length=250)
def __str__(self):
return self.cycle_name + " -- " + self.cycle_description
class Program(models.Model):
program_name = models.CharField(max_length=50)
program_description = models.CharField(max_length=250)
cycles = models.ManyToManyField(Cycle)
is_favourite = models.BooleanField(default="False")
def get_absolute_url(self):
return reverse('programs:program', kwargs={'pk': self.pk})
def __str__(self):
return self.program_name
in views.py
class AllProgramsView (generic.ListView):
template_name = 'programs/index.html'
context_object_name = 'programs_list'
def get_queryset(self):
return Program.objects.all()
class ProgramDetailView (generic.DetailView):
model = Program
template_name = 'programs/program.html'
in urls.py
#list of all programs
url(r'^$', views.AllProgramsView.as_view(), name='index'),
#single program page
url(r'^(?P<pk>[0-9]+)/$', views.ProgramDetailView.as_view(), name='program'),
In the single program page I need to list all the cycles that are contained in that specific program.
I've been trying so many different things but none seems to be right.
Here's my current take for the template, which however does not work:
program.html
<div class="bg-white">
<div class="container text-center text-muted">
<div class="row">
{% if cycle %}
{% for cycle in program.cycles.all() %}
<div class="col-sm-4 py-4">
<div class="card">
<p><h5>{{ cycle.cycle_name }}</h5></p>
<p class="card-text">{{ cycle.cycle_description }}</p>
Modify it
</div>
</div>
{% endfor %}
{% else %}
<div class="col-sm-12">
<p>No cycles found</p>
</div>
{% endif %}
</div>
</div>
Can someone help, please? Thanks.
I think that you get no context because the if statement is wrong.
Instead of
{% if cycle %}
it should be
{% if program.cycles %}
