You do not have a "User" view inside your views.py.
path('teacher/', views.User, name='teacher')
But a TeacherView. I suggest you use a Template View and define your Users Context
https://docs.djangoproject.com/en/2.0/ref/class-based-views/base/#templateview
And if I might suggest, do not prefix Model Attributes with "u". You User Model already speaks for itself. Even though naming it "User" might clash at a certain point of time with the Auth User Model from Django.
And last but not least try to avoid * imports if you can
change the views.py as follows
from django.views import View
class TeacherView(View):
def get(self, request):
return render(request, 'Dashboard/teacher.html', {'table' : User.objects.all()})
Now also change the urlpatterns as follows
path('teacher/', views.TeacherView.as_view(), name='teacher')
I hope this works for you.

'blog' object has no attribute 'get'. I want to do mini blog on my website,but it isnt working now. I would like to get all objects from database.(Sorry,If I did something wrong,I am beginner in django and tried to functions for my website) :)

path('vds', views.vds, name='vds' ),
path('minecraft', views.minecraft, name='minecraft' ),
path('about', views.about, name='about'),
path('blog', views.blog, name='blog')
]
The actual error is probably caused by the wrong url pattern:
path('blog', views.blog, name='blog')
views.blog refers to the blog model due to:
from polls.models import blog
What you need here is the view not the model, so:
path('blog', views.messagesblog, name='blog')
Then, remove the "self" argument from your messagesblog function.
Use the "render" function from django.shortcuts and provide a context with the blog objects:
def messagesblog(request):
return render(request, "blog.html", {message: blog.objects.all()})
That might solve your problem.
Still, there are some things you could improve.
E.g.: Don't use "id" fields in your model definitions if you don't really, really have to, as this is usually an auto-generated number (BigInt) field.
That's only one tip from an old Django veteran happy to be finally heard. You'll find out much more yourself as you proceed.
My goal is to Create hyperlinks which would toss a keyword into a views function which would then pull a query from my db onto the page.
GOAL: Press hyperlink which would give me query of a specific major.
I was attemping to use the converter,
So the goal was, 1 being the first step, 3 being final step.
Is this possible?
1) Click the hyperlink -> Major = Accounting
2)URL.py
path(<str:Accounting/, views.Major, name=Major)
3)Views.py
def Major(request, Accounting):
major_choice = professor.objects.filter(Major = Accounting)
return render(request, 'locate/major.html', {'major_choice': major_choice})
NOTE: I replaced variables with what I want it to contain "Accounting", you will notice inside the bottom views.py its called "Major".
Index.html
Accounting
major.html
<ul>
{% for major in major_choice %}
<li>{{major.ProfessorName}}</li>
{%endfor%}
</ul>

ProfessorIDS = models.IntegerField()
ProfessorName = models.CharField(max_length=100)
ProfessorRating = models.DecimalField(decimal_places=2,max_digits=4)
NumberofRatings = models.CharField(max_length=50)

def __str__(self):
return self.ProfessorName

def Major(request, major):
major_choice = professor.objects.filter(Major = major)
return render(request, 'locate/major.html', {'major_choice': major_choice})
Please update your url path to this:
path('<str:Major>/', views.Major, name='Major')
And in your html:

I want to use the {{ post.title }} and {{ for post in object_list }}
into my home template to show the latest 4 posts, I tried to import from blog.models import Post, but it doesn't work. I guess I'm putting it in the wrong place.

class Post(models.Model):
title = models.CharField(max_length = 140)

home.views
from django.views.generic import TemplateView
from allauth.account.forms import LoginForm
class HomePageView(TemplateView):

mysite tree look like this
mysite

You can override get_context_data and add the latest blog posts to the template context.
from blog.models import Post
class HomePageView(TemplateView):
template_name = 'home/index.html'
def get_context_data(self, **kwargs):
context = super(HomePageView, self).get_context_data(**kwargs)
context['object_list'] = Post.objects.order_by('-date')[:4]
return context
I am a beginner to Django.
I want to create a form that allow user to store their data to the database, but I face to an issue.
If I add data through Django admin, the data will shown correctly. But if I add data through my form. Data will store into database successfully but they don't shown in my Django admin.
Note: The Django version I used is 1.11.2
The is my Django admin page. There are 8 data in the database but just show the one I added by the Django admin.

I was writing a model online shop django app, wanted to incorporate slug in it. Having trouble in opening a page.
This is my model:
from __future__ import unicode_literals
from django.db import models
from django.db.models.signals import pre_save
from django.utils .text import slugify
class Customer(models.Model):
customer_name = models.CharField(max_length=200)
slug = models.SlugField(unique = True)
def __str__(self):
return self.customer_name
def get_absolute_url(self):
return reverse("OnlineShop:order", kwargs={"slug": self.slug})
def pre_save_customer_receiver(sender, instance, *args, **kwargs):
slug = slugify(instance.customer_name)
exists = Customer.objects.filter(slug = slug).exists()
if exists:
slug = "%s-%s" % (slug,instance.id)
instance.slug=slug
pre_save.connect(pre_save_customer_receiver, sender = Customer)
This is my view:
def customer(request):
customer_list = Customer.objects.all()
template_path = 'OnlineShop/customer.html'
context={
'customer_list':customer_list,
}
return render(request,template_path,context)
def order(request,slug):
Customer = Customer.objects.filter(slug=slug)
''' some code from here '''
And my template customer.html:
<h1>List of Customers:</h1>
<ul>
{% for customer in customer_list %}
<li><a href='{% url 'order' customer.slug %}'>{{ customer.customer_name }}<br></li>
{% endfor %}
</ul>
This is my urls.py
from django.conf.urls import url
from . import views
urlpatterns=[
url(r'^$',views.customer, name='customer'),
url(r'^customer/(?P<slug>[\w-]+)$',views.order, name='order'),
]
Is the problem in the template? What is wrong?
I hope you've defined your urls.py like below,
from django.conf.urls import url, include
from . import views
onlineshop_patterns = [
url(r'^$', views.customer, name='customer'),
url(r'^customer/(?P<slug>[\w-]+)$', views.order, name='order'),
]
urlpatterns = [
# ...
url(r'^OnlineShop/', include(onlineshop_patterns)),
# ...
]
