am working on a Django project where showing the details of post and amount
here is my models.py of post
class Loader_post(models.Model):
user = models.ForeignKey(User, on_delete=models.CASCADE ,related_name="Loader")
pick_up_station = models.CharField(max_length=150)
destination_station = models.CharField(max_length=150)
sender_name = models.CharField(max_length=150)
phone_number = PhoneNumberField(null=False, blank=False, unique=True)
receiver_name = models.CharField(max_length=150)
def __str__(self):
return self.user.username
def get_absolute_url(self):
return reverse("Loader:my_job", kwargs={"pk": self.pk})
this is my second models which I inherit Loader post
class price(models.Model):
my_post = models.ForeignKey(Loader_post, related_name='prices',on_delete=models.CASCADE,
null=True, default='')
user = models.ForeignKey(get_user_model(), on_delete=models.CASCADE, null=True, default='')
driver_price = models.CharField(max_length=150, null=True)
driver_name = models.CharField(max_length=150, null=True)
approved_price = models.BooleanField(default=False)
status = models.BooleanField(default=False)
def get_absolute_url(self):
return reverse("Driver:Driverview")
def __str__(self):
return self.driver_price
this is the view.py of both list and details view
class offer_view(ListView, SelectRelatedMixin):
context_object_name = 'offern'
model = Loader_post
template_name = "offer.html"
def get_queryset(self):
qs = Loader_post.objects.filter(user=self.request.user)
return qs
class offer_view_detail(DetailView):
context_object_name = 'offernew'
model = Loader_post
template_name = "offer_detail.html"
here is my HTML page of list view ...when someone clicks on it it shows the detail of next post
offer.html
{% for my in offern %}
{{my.sender_name}} {% endfor %}
and when someone clicks on its route to the detail page .. but it shows template doesn't exist
this is my detail page ie. offer_details.hml
<p>{{offernew.sender_name}}</p>
<p>{{offernew.receiver_name}}</p>
{% for x in offernew.prices.all %}
<p>
<p>{{x.driver_name}}</p>
</p>
and this is urls.py
path('offerdetail/<int:pk>', views.offer_view_detail.as_view(),name="offerdetail"),
path('offer/', views.offer_view.as_view(), name="offer"),
Following on from comments,
In you ListView,
{{my.sender_name}}
here, the url specified is not defined in your urls.py, that's why it was showing no template doesn't exist, changing to this would solve this.
{{my.sender_name}}
Now, To show prices model in your DetailView, i would do something like this.
class offer_view_detail(DetailView):
context_object_name='offernew'
model = Loader_post
template_name = "offer_detail.html"
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
context['price_model'] = self.object.prices.all()
return context
and In your Template
<p>{{offernew.sender_name}}</p>
<p>{{offernew.receiver_name}}</p>
{% for x in offernew.price_model %}
<p>{{x.driver_name}}</p>
{% endfor %}

I am creating a blog app in django. For that, I have made a page where all available blogs are listed. I am using generic.ListView view to achieve this. But, I also want to create a writer's section where I can list some details about the writers that have written those blogs. For this, I need to get all the users that have written a blog and then find distinct users from that and list out their username. I have an author field in my Blog model that keeps track of the writer user. How can I get the distinct usernames of these writers and pass it into my template?
Models.py:
class Blog(models.Model):
blog_head = models.CharField(max_length=100)
blog_header_image = models.ImageField(upload_to="photos/blogs/", null=True, blank=True)
#blog_content = models.TextField()
blog_content = RichTextField(blank=True, null=True)
#blog_summary = models.TextField(max_length=355)
blog_summary = models.CharField(max_length=100)
author = models.ForeignKey(User, on_delete=models.CASCADE)
blog_date = models.DateField(auto_now_add=True)
likes = models.ManyToManyField(User, related_name='blog_post_likes', blank=True)
def __str__(self):
return self.blog_head
def get_absolute_url(self):
return reverse('blog-full', args=[str(self.id)])
def blog_likes_count(self):
return self.likes.count()
Views.py:
class blogs_getting_Listview(ListView):
model = Blog
template_name = 'blogs.html'
ordering = ["-blog_date"]
def get_context_data(self, *args, **kwargs):
context = super(blogs_getting_Listview, self).get_context_data()
authors_id_list = Blog.objects.get(id=id).author
authors_list = ""
for author_in in authors_id_list:
author_obj = User.objects.get(id=author_id)
authors_list = authors_list + author_obj
context.update({
"authors_list": authors_list
#'more_context': Model.objects.all(),
})
print(type(context["authors_list"]))
return context
urls.py:
urlpatterns = [
#path('', views.blogs_getting, name='blogs/'),
path('', blogs_getting_Listview.as_view(), name='blogs/'),
path('blog/<int:pk>', blogs_getting_Detailview.as_view(), name='blog-full'),
path('new_blog/', add_blog_view.as_view(), name='add_blog'),
path('update_blog/<int:pk>', edit_blog_view.as_view(), name='update_blog' ),
path('delete_blog/<int:pk>', delete_blog_view.as_view(), name='delete_blog' ),
path('like/<int:pk>', like_view, name='like_blog' ),
]+static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
template:
{% for author in authors_list %}
<p>{{ author }}</p>
{% endfor %}
(Here I am trying to render the author objects' queryset on my page.)
Thankful for any help
Try accessing directly the author entitie:
class blogs_getting_Listview(ListView):
model = Blog
template_name = 'blogs.html'
ordering = ["-blog_date"]
def get_context_data(self, *args, **kwargs):
context = super(blogs_getting_Listview, self).get_context_data()
authors = Blog.objects.get(id=id)
authors_list = ""
for author in authors:
author_obj = User.objects.get(id=author.id)
authors_list.append(author_obj)
context["authors_list"] = authors_list
return context
I have a django UpdateView which needs to inherit three different models and different models. CreateView is working fine with three different modelforms.
models.py:
class Employee(models.Model):
"""
Create employee attributes
"""
employee_user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, null=True)
e_id = models.IntegerField(unique=True, null=True, blank=True)
first_name = models.CharField(max_length=128,blank=True)
last_name = models.CharField(max_length=128, blank=True)
.....
class WorkExperience(models.Model):
"""
Stores employee previous work experiences
"""
employee = models.ForeignKey('Employee', related_name='we_employee', on_delete=models.CASCADE, null=True)
previous_company_name = models.CharField(max_length=128, null=True)
job_designation = models.CharField(max_length=128, null=True)
from_date = models.DateField(null=True)
......
class Education(models.Model):
"""
Stores employee education background
"""
employee = models.ForeignKey('Employee', related_name='edu_employee', on_delete=models.CASCADE, null=True)
institution_name = models.CharField(max_length=128, null=True)
degree = models.CharField(max_length=128, null=True)
.....
views.py:
class EmployeeUpdateView(LoginRequiredMixin,UpdateView):
"""
Update a created a employee
"""
login_url = '/authentication/login/'
template_name = 'employee/employee_add_form.html'
form_class = EmployeeAddModelForm
work_form_class = WorkExperienceForm
education_form_class = EducationForm
queryset = Employee.objects.all()
def form_valid(self, form):
print(form.cleaned_data)
return super().form_valid(form)
def get_object(self):
id_ = self.kwargs.get("id")
return get_object_or_404(Employee, id=id_)
WHen I go to Update view, I am only able to update EmployeeAddModelForm values. But other form's(WorkExperienceForm, EducationForm ) fields do not appear let alone edit the values of the fields.
I suppose my views.py is not correct.
I need suggestion to correct my updateview.
If you want to put multiple forms in one HTML file, in my way, write as follows.
class EmployeeUpdateView(LoginRequiredMixin,UpdateView):
login_url = '/authentication/login/'
def form_valid(self, form):
print(form.cleaned_data)
return super().form_valid(form)
def get(self, request, *args, **kwargs):
id_ = self.kwargs.get("id")
user = Employee.objects.get(id=id_)
work = WorkExperience.objects.get(employee=user)
education = Education.objects.get(employee=user)
return render(request, self.template_name, {
'form': EmployeeAddModelForm(instance=user),
'work_form': WorkExperienceForm(instance=work),
'education_form': EducationForm(instance=education)
}
)
def post(self, request):
first_name = request.POST['first_name']
# Your own code...
.....
I think the argument of each form depends on the definition of Form.
And in a very simple way, the HTML file looks like this:
<body>
<form method="post">
{% csrf_token %}
{{ employ_form }}
{{ work_form }}
{{ edu_form }}
<button type="submit">OK</button>
</form?
</body>
</html>
I'm not sure if this is the best option.
How about putting forms into get_context_data?
Something like
context['form1'] = EmployeeAddModelForm()
context['form2] = WorkExperienceForm()
Etc.
Edit:
def get_context_data(self, **kwargs):
context = super(EmployeeUpdateView, self).get_context_data(**kwargs)
context['form'] = EmployeeAddModelForm()
context['form2'] = WorkExperienceForm()
context['form3'] = EducationForm()
return context
I am building a blog in django 3. I want to filter all posts by author and display the results in author page. I can't seem to figure what is wrong with my code. Please help. If i can get an explaination on what is wrong with my code, that will be appreciated.
Views.py
class AuthorPostListView(ListView):
model = Post
paginate_by = 5
template_name = 'author_post.html'
def get_queryset(self):
return Post.objects.filter(author = self.request.user).order_by('created_on').reverse()
def get_context_data(self):
context = super(AuthorPostListView, self).get_context_data(**kwargs)
context['authorpost_list'] = Post.objects.all()
return context
Models.py
class Post(models.Model):
title = models.CharField(max_length=200)
post_slug = models.SlugField(max_length = 200, unique = True)
body = models.TextField()
created_on = models.DateTimeField(auto_now_add=True)
last_modified = models.DateTimeField(auto_now = True)
author = models.ForeignKey(
settings.AUTH_USER_MODEL,
on_delete=models.CASCADE,
related_name = 'blog_posts',
)
post_picture = models.ImageField(
upload_to = 'post_picture',
null = True,
blank = True,
default='/media/post_picture/2.jpg',
)
approved_comment = models.BooleanField(default=True)
tags = TaggableManager()

def approve(self):
self.approved_comment = True
self.save()
class Meta:
ordering = ['created_on']
def __str__(self):
return self.title
def get_absolute_url(self):
return reverse('post_detail', args=[str(self.id)])
def save(self, *args, **kwargs):
self.slug = slugify(self.title)
super(Post, self).save(*args, **kwargs)
Template
{% for object in authorpost_list %}
{{ object.title }}
{% endfor %}
urls.py
urlpatterns = [
path('author_post/', views.AuthorPostListView.as_view(), name = 'author_posts'),
]
you are over-riding the actual view you wanted with get context data, so you can remove the get context method and call in the template as
{% for object in object_list %}
{{ object.title }}
{% endfor %}
or you can do
context['authorpost_list'] = Post.objects.filter(author = self.request.user).order_by('-created_on')
and call in template in the same way as you shown
How can I display the list of users with the count of total number of posts made by them in a separate HTML page ?
models.py
class Post(models.Model):
author = models.ForeignKey(User.request, on_delete = models.CASCADE)
title = models.CharField(max_length=100)
text = models.TextField()
slug = models.SlugField(unique=True, blank=True, default=uuid.uuid1)
created_date = models.DateTimeField(default=timezone.now)
likes = models.ManyToManyField(User, related_name='post_likes', blank = True)
def get_like_url(self):
return reverse("posts:like-toggle", kwargs={"slug": self.slug})
def get_api_like_url(self):
return reverse("posts:like-api-toggle", kwargs={"slug": self.slug})
def get_absolute_url(self):
return reverse("post_detail",kwargs={'pk':self.pk})
def __str__(self):
return self.title
def count_posts_of(user):
return Post.objects.filter(author=user).count()
You have to learn MVC architecture(MVT in django).
As a beginner first create a sample project to understand this - https://docs.djangoproject.com/en/2.0/intro/tutorial01/
Learn how models.py are written - https://docs.djangoproject.com/en/2.0/topics/db/models/
and how to writeviews.py - https://docs.djangoproject.com/en/2.0/topics/class-based-views/
Then connect them in urls.py - https://docs.djangoproject.com/en/2.0/topics/http/urls/
This is my solution at the moment, but it could be done differently.
First, add count_posts_of method to your User model whatever it is.
For instance I myself created a user model and add this method to it as following:
models.py
class User(models.Model):
name = models.CharField(max_length=100, blank=True, null=True)
#property
def count_posts_of(self):
return self.post_set.all().count()
now in the view pass all the users as context:
views.py
def user_post(request):
context = {'users': User.objects.all()}
return render(request, 'future/user_post_view.html', context)
and finally in the template show the user and their posts' count:
user_post_view.html
{% for user in users %}
{{ user.name }} :
{{ user.count_posts_of }},
{% endfor %}
i have a problem in my django project. when i want show posts that belongs to specific user id this show me this error
urls.py:
url(r'^profile/(?P<user>\d+)/$', profile)
views.py:
def profile(request, user=None):
queryset = Post.objects.filter(user=user)
context ={
"object_list" : queryset,
}
return render(request, 'profile.html', context)
html page:
{% if request.user.is_authenticated %}
<li>My ADS</li>
models.py:
class Post(models.Model):
"""docstring for Post"""
user = models.ForeignKey(settings.AUTH_USER_MODEL, default=1)
post_title = models.CharField(max_length=50)
image = models.ImageField(upload_to = 'user/',null=True, blank=True, height_field="height_field", width_field="width_field")
height_field = models.IntegerField(default=0)
width_field = models.IntegerField(default=0)
content = models.TextField()
updated = models.DateTimeField(auto_now=True, auto_now_add=False)
timestamp = models.DateTimeField(auto_now=True, auto_now_add=False)
def __str__(self):
return (self.post_title)
def get_absolute_url(self):
return reverse("posts:detailpost", kwargs={"id": self.id})
The {% url %} tag takes the name of the URL pattern, not the path. You should give the pattern an name:
url(r'^profile/(?P<user>\d+)/$', profile, name='profile')
and use the tag like this:
{% url 'profile' user=request.user.id %}
