I am working on a To-do app. The individual to-dos reference a to-do list via a foreign key and the to-do lists reference a project via a foreign key.
I want the to-do's status to be set to true when clicked. I have seen some tutorials where this is done but I haven't been able to get this to work yet.
Here are the models:
class Project(models.Model):
title = models.CharField(max_length= 200)
description = tinymce_models.HTMLField()
status = models.CharField(max_length=20, choices=PROJECT_CHOICES, default="active")
date = models.DateTimeField(auto_now_add=True, null=True)
def __str__(self):
return self.title
def get_absolute_url(self):
return reverse ('project_detail', args=[str(self.id)])
class ProjectTodoGroup(models.Model):
title = models.CharField(max_length=250)
description = tinymce_models.HTMLField()
project = models.ForeignKey(Project, blank=True, on_delete=models.CASCADE, related_name='todo_group')
date = models.DateTimeField(auto_now_add=True, null=True)
def __str__(self):
return self.title
class ProjectTodo(models.Model):
title = models.CharField(max_length= 250)
notes = tinymce_models.HTMLField()
status = models.BooleanField(default=False)
projectgroup = models.ForeignKey(ProjectTodoGroup, blank=True, null=True, on_delete=models.CASCADE, related_name='todo_set')
date = models.DateTimeField(auto_now_add=True, null=True)
def __str__(self):
return self.title
The view:
model = ProjectTodo
fields = ['status']
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
def get_success_url(self):
return reverse('company_project:todo_group_detail', args=[self.kwargs.get('pk'), (self.object.id)])
Everything I have tried to far with the view hasn't worked.
The template:
{% extends 'base.html' %}
{% load crispy_forms_tags %}
{% block content %}
<div class="section-container container">
<div class="todo-group">
<h2>{{ projecttodogroup.title }}</h2>
<p>{{ projecttodogroup.description | safe }}</p>
</div>
<div><b>Todos</b></div>
{% if projecttodogroup.todo_set.all %}
{% for todo in projecttodogroup.todo_set.all %}
<div class="todos" style="padding: 10px;">
{{ todo.title }}
</div>
{% endfor %}
{% else %}
<p>No Todos have been have been added yet.</p>
{% endif %}
<h1>Add Todo</h1>
<form action="" method="post">
{% csrf_token %}
{{ form.media }}
{{ form|crispy }}
<input type="submit" value="save">
</form>
</div>
{% endblock content %}

Coding some kind of blog with django, and I can't make homepage to contain images of the articles... It just doesn't upload a image...
my Views.py :
class AddPostView(CreateView):
model = Post
form_class = PostForm
template_name = 'add_post.html'
my Models.py:
class Post(models.Model):
title = models.CharField(max_length=255)
title_tag = models.CharField(max_length=255, default="YNTN")
#author = models.ForeignKey(User, on_delete=models.CASCADE)

def total_likes(self):
return self.likes.count()
def __str__(self):
return (self.title + " | " + str(self.author))
def get_absolute_url(self):
return reverse("home")
My Forms.py:
class PostForm(forms.ModelForm):
class Meta:
model = Post
fields = ('title', 'title_tag', 'body', 'image')
widgets = {
'title': forms.TextInput(attrs={'class':'form-control', 'placeholder':'Title of the Blog'}),
'title_tag': forms.TextInput(attrs={'class':'form-control', 'placeholder':'Copy the title with no space and a hyphen in between'}),
'body': forms.Textarea(attrs={'class':'form-control', 'placeholder':'Content of the Blog'}),
}
and my add_post.html :
{% extends 'base.html' %}
{% block title %}Make an article{% endblock %}
{% block content %}
{% if user.is_authenticated %}
<h1>Make an article</h1>
<div class="form-group">
<form method="POST">
<br/>
{% csrf_token %}
{{ form.media }}
{{ form.as_p }}
<button class="btn btn-dark">POST</button>
</div>
{% else %}
<h1>You are not allowed to post! You need to Log in or Register</h1>
{% endif %}
{% endblock %}
I tried on many ways but never worked..
You are missing enctype="multipart/form-data" (as mentioned in the documentation) in the form tag inside the html template. Update the html file like this:
<form method="POST" enctype="multipart/form-data">
<br/>
{% csrf_token %}
{{ form.as_p }}
<button type="submit" class="btn btn-dark">POST</button>
</form>
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.

I have to let the "comment" show in the report_detail.html
I an using Django 2.2 , I have tried to add some code to views.py but failed. The Report need to show the comment below, however, I try add some code in views.py and report_detail.html but it can not work, how can I do ? thank you
models.py
class Report(models.Model):
done = models.TextField('what done')

<div class="article-entry">

<p>by {{ object.author }} | {{ object.date }}</p>
<p>{{ object.willDo }}</p>

I think that what you want to do is just this:
<div class="article-entry">
<h2>{{ object.done }}</h2>
<p>by {{ object.author }} | {{ object.date }}</p>
<p>{{ object.willDo }}</p>
{% for comment in object.comments.all %}
<p>{{ comment.comment }}</p>
{% endfor %}

Problem
I am building a forums and am trying to get my homepage to show the last post in a forum.
I have got it to work to show all threads, but i just want the latest one to show on the latest post div.
I setup the get_latest_by on the Thread model so that it gets the latest one by the time created.
How would i be able to get this to display the latest thread?
You can set a property on the Form model, and then call it in the template.
views.py
class Form(models.Model):
...
#property
def get_newest_thread(self):
return self.threads.all().order_by('date_posted').first()
html
{% with threads=forum.get_newest_thread %}
<div class="float-right" id="latest-post">
<p>{{ threads.title }}</p>
<p> {{ threads.author.username }} </p>
</div>
{% endwith %}
I have 2 model objects, Business & BusinessImage as so, listed with views and index.html. I am trying to list the business's featured image, but it's not happening. I am getting the following error:
'QuerySet' object has no attribute 'businessimage_set'
How can I get the business featured image for a list?
Business
class Business(models.Model):
name = models.CharField("Name", max_length=70, default="Business Name")
slug = models.SlugField()
description = models.TextField("About", max_length=400)
category = models.ManyToManyField(Category, verbose_name="Categories", blank=True)
order = models.IntegerField("Order", default=0)
claimed = models.BooleanField("Claimed", default=False)
featured = models.BooleanField("Featured", default=False)
class Meta:
ordering = ['order']
verbose_name = "Business"
verbose_name_plural = "Businesses"
def __str__(self):
return self.name
BusinessImage
class BusinessImage(models.Model):
business = models.ForeignKey(Business)
image = models.ImageField(upload_to="images/business")
title = models.CharField(max_length=120)
featured = models.BooleanField(default=False)
timestamp = models.DateTimeField(auto_now_add=True, auto_now=False)

from .models import Business, BusinessImage
def index_view(request):

context = RequestContext(request, {
'latest_business_list': latest_business_list,
'images': images,
})
return HttpResponse(template.render(context))
index.html
{% block content %}
<div class="text-center business_title">
<h2>Featured</h2>
</div>
{% if latest_business_list %}
{% for business in latest_business_list|slice:":4" %}
{% if business.active %}
<div class="col-sm-6 col-md-3">
<li>{{ business.name }}</li>
{% for image in latest_business_list.businessimage_set.all %}
{% if image.featured %}
<a href="{% url 'single_product' product.slug %}">
<img src="{{MEDIA_URL}}{{image.image}}" alt="{{image}}">
</a>
{% endif %}
{% endfor %}
</div>
{% endif %}
{% endfor %}
{% endif %}
{% endblock %}
businessimage_set is an attribute of a Business instance, but you're trying to access it as an attribute of a queryset (i.e. list of businesses). If your goal is just to be able to access the images for each business in a template, you can leave out images entirely. Instead your template would have:
{% for image in business.businessimage_set.all %}
(Though look into prefetch_related for efficiency.)
