Django AssertionError when testing Create View

I'm running some tests for my app 'ads', but when I try to test the CreateView it fails with the following message:
AssertionError: 'just a test' != 'New title'
Here's the test:
class AdTests(TestCase):
def setUp(self):
self.user = get_user_model().objects.create_user(
username='test_user',
email='test#email.com',
password='secret'
)
self.ad = Ad.objects.create(
title='just a test',
text='Ehy',
owner=self.user
)
def test_ad_create_view(self):
response = self.client.post(reverse('ads:ad_create'), {
'title': 'New title',
'text': 'New text',
'owner': self.user.id,
})
self.assertEqual(response.status_code, 302)
self.assertEqual(Ad.objects.last().title, 'New title')
self.assertEqual(Ad.objects.last().text, 'New text')
So it could be that the test fails in creating a new ad, and then it compares the fields with the first ad in the setUp method.
I upload the rest of the code if it can help:

I hope it is useful, thanks in advance!

According to Django Doc
Create View:
A view that displays a form for creating an object, redisplaying the form with validation errors (if there are any) and saving the object.
This is not a Valid way to do create View based on my experience. Check the doc Doc here.
if i understand what you are talking about You want to submit Ad Model using Create View, if you want to submit it in form You can something like this:
from django.views.generic import CreateView
from django.contrib.auth.mixins import LoginRequiredMixin
from django.urls import reverse_lazy,
class PostCreativeView(LoginRequiredMixin, CreateView):
model = #Your Model
fields = [#Fields of the model You want to submit]
template_name = #html template you want to submit the form
success_url = reverse_lazy(#url for redirected user when the form is submitted)
def form_valid(self, form):
form.instance.user = self.request.user
return super (PostCreativeView, self).form_valid(form)
in the form template you can add:
<form method="post">
{% csrf_token %}
{{ form.as_p }}
<input type="submit" value="Save">
</form>
for styling you can follow this: Answer

If you are using Django model form than you have to do something like this first create form class
class Kesif_Form(ModelForm):
class Meta:
model = Iletisim
fields = '__all__'#here you to defined specific you field or all the field
than you have to submit it like this
def kesif_kayit(request):
if request.method=='POST':
form = Kesif_Form(request.POST)
if form.is_valid():
form.save()
return redirect('index')
else:
form = Kesif_Form()
context={'form' : form}
return render(request,'index.html',context)
you don't have save it manually Django Model Form will save it for you.

Django unable to upload image file

I was trying out ImageField in the models, But Image upload do not work when I try to upload from the forms. But it works when I upload it from the admin page.
Any way to debug is also helpful
My model-
class Inventory(models.Model):
"""docstring for Inventory"""
name = models.CharField(max_length=100,default='Something')
image = models.ImageField(null=True, blank=True)
description = models.CharField(max_length=100, default='Describe Something')
price = models.IntegerField( default=0)
My Form-
class InventoryForm(forms.ModelForm):
class Meta:
model = Inventory
fields = ['name','description','price','image']
widgets = {
'name' : forms.TextInput(attrs={"placeholder":"Name", "onfocus":"this.value = '';","onblur":"if (this.value=='') this.value = this.defaultValue","required":""}),
'description' : forms.TextInput(attrs={"placeholder":"Email", "onfocus":"this.value = '';","onblur":"if (this.value=='') this.value = this.defaultValue","required":""}),
'price' : forms.NumberInput(attrs={"placeholder":"Price","onfocus":"this.value = '';","onblur":"if (this.value=='') this.value = this.defaultValue","required":""}),
}
Settings -
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, "media/")
template -
<form action="" method="post" enctype="multipart/form-data"> {% csrf_token %}
{{form}}
<input type="submit" value="Send">
</form>
url -
from django.contrib import admin
from django.urls import path, include, re_path
from django.conf import settings
from django.conf.urls.static import static
urlpatterns = [
path('',include('inventory.urls')),
path('<int:id>',include('inventory.urls')),
path('admin/', admin.site.urls),
]+ static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
My Views-
def index(request):
form = InventoryForm(request.POST or None)
if form.is_valid():
form.save()
form = InventoryForm()
else:
form = InventoryForm()
inventory = Inventory.objects.all()
context = {'form' : form, 'all_inventory' : inventory}
return render(request, 'inventory/index.html',context)
Regards,

In your views.py. Change:
form = InventoryForm(request.POST or None)
to
form = InventoryForm(request.POST, request.FILES or None)
Because, Files in django post request are in request.FILES dictionary. You have to send that to forms as well.

How about adding upload_to in models in image field and add default image also this will come in handy later on or not your choice:
models.py
class Inventory(models.Model):
"""docstring for Inventory"""
name = models.CharField(max_length=100,default='Something')
image = models.ImageField(upload_to='/your_file_name/',default='default.png')
description = models.CharField(max_length=100, default='Describe Something')
price = models.IntegerField(default=0)

Why is my Django form is not displaying anything?

I am following a tutorial in which we will create a form to hold simple object parameters.
Here's the code:
forms.py
from django.forms import ModelForm
from .models import Item
class ItemForm(ModelForm):
class Meta:
model = Item
fields = ['item_name', 'item_desc', 'item_price', 'item_image']
models.py
from django.db import models
class Item(models.Model):
def __str__(self):
return self.item_name
item_name = models.CharField(max_length = 200)
item_desc = models.CharField(max_length= 200)
item_price = models.IntegerField()
item_image = models.CharField(max_length=500, default ="https://i.jamesvillas.co.uk/images/jvh/holiday-destinations/resort/food-placeholder.jpg" )
urls.py
from . import views
from django.urls import path
urlpatterns = [
path('', views.index, name = 'index'),
path('item/', views.item, name = 'item'),
path('info/', views.info, name = "info"),
path('<int:item_id>/', views.detail, name = "detail" ),
#add form
path('add', views.create_item, name = "create"),
]
views.py
from django.shortcuts import render, redirect
from django.http import HttpResponse
from .models import Item
from django.template import loader
from .forms import ItemForm
#Some code here
def create_item(request):
form = ItemForm(request.POST or None)
if (form.is_valid()):
form.save()
return redirect('food/index')
return render(request, 'food/item-form.html', {'form': form})
food/item-form.html
<form method = "POST">
{% csrf_token %}
{{ form }}
<button type= "Submit" >Save</button>
</form>
Now when I go to http://localhost:8000/food/add, it displays an empty page! I have followed the tutorial the exact same way then why is My project not working?

correct your views.py
from django.http import HttpResponseRedirect
from django.shortcuts import render
from .forms import NameForm
def get_name(request):
# if this is a POST request we need to process the form data
if request.method == 'POST':
# create a form instance and populate it with data from the request:
form = NameForm(request.POST)
# check whether it's valid:
if form.is_valid():
# process the data in form.cleaned_data as required
# ...
# redirect to a new URL:
return HttpResponseRedirect('/thanks/')
# if a GET (or any other method) we'll create a blank form
else:
form = NameForm()
return render(request, 'name.html', {'form': form})

{{form.as_ul}}
<input type="submit" name="submit" value="create"/>
</form>
This is what i am doing but still i am unable to access form. Where i am doing wrong. will be grateful to you. Please mark that what's wrong in code?

as per you code and your explanation in question .please see your code in urls.py
urlpatterns += patterns('',
url(r'^xyz/$', create_book)) # you should write like ^xyz/$
Please follow django doc

Two Syntax Problems:
1) Always define your processor name in " " like #processor_for("Author")
2) urls for page processors like :
url("^xyz/$", "mezzanine.pages.views.page", {"slug": "Author"}, name="Author"),
