I don't know what causes an error it gives error locations in Exception

In urls.py, instead of just UserListView, use UserListView.as_view(). It's how Django's class based views work.

I tried chnaging the img src call to a d.image.url call,and alot of other things it just doesnt load, the view just doesnt load this field even tho they are available in the database
Change your template with
{% for d in donations %}
<tr>
<th scope="row">1</th>
<td>{{d.product_name}}</td>
<td>{{d.product_description}}</td>
<td>{{d.get_category_display}}</td>
<td>{{d.station}}</td>
<td>
<img src="{{d.image.url}}" width="120"/>
</td>
<td><button type="button" class="btn btn-success">Add</button></td>
</tr>
{% endfor %}
Explanation:
For each model field that has choices set, Django will add a method to retrieve the human-readable name for the field’s current value. See get_FOO_display() in the database API documentation.
get_FOO_display
Docs: https://docs.djangoproject.com/en/4.0/ref/models/fields/#choices
I want to display all the users, in my template but I i received this error.
TypeError at /list/
init() takes 1 positional argument but 2 were given
views.py
class UsersView(TemplateView):
template_name = 'list.html'
context = super(UsersView, self).get_context_data(**kwargs)
context['object_list'] = User.objects.values()
list.html
<tbody>
<tr>
<th scope="col">Id</th>
<th scope="col">username</th>
<th scope="col">email Adress</th>
<th scope="col">First Name </th>
<th scope="col">Last Name</th>
</tr>
</thead>
<tbody>
{% for user in users %}
<tr>
<td>{{ user.id }} </td>
<td>{{ user.username}}</td>
<td>{{ user.email }}</td>
<td>{{ user.first_name}}</td>
<td>{{ user.last_name }}</td>
How could you pull all users?
There is no self nor context, etc. in a class. You should override the .get_context_data(…) method [Django-doc]:
class UsersView(TemplateView):
template_name = 'list.html'
def get_context_data(self, *args, **kwargs):
context = super(UsersView, self).get_context_data(*args, **kwargs)
context['object_list'] = User.objects.all()
return context
You named your template variable ojbect_list, so you should iterate over object_list, not users:
{% for user in object_list %}
<tr>
<td>{{ user.id }} </td>
<td>{{ user.username}}</td>
<td>{{ user.email }}</td>
<td>{{ user.first_name}}</td>
<td>{{ user.last_name }}</td>
</tr>
{% endfor %}
It might however make more sense to use a ListView [Django-doc] instead:
from django.views.generic.list import ListView
class UsersView(ListView):
template_name = 'list.html'
model = User

THERE IS NO THUMBNAIL SHOWING THE RESULT FOR IMAGE IS LIKE THAT : /media/photo/01.jpg
everythink else is fine. Thank you.
i found the reason;
in template.py
<tr>
<th scope="row">{{ obj.id }}</th>
THIS CODE SHOULD BE ---> <td>{{ obj.photo.url }}</td>
<td>{{ obj.title }}</td>
<td>{{ obj.date }}</td>
</tr>
<tr>
<th scope="row">{{ obj.id }}</th>
LIKE THIS ONE ---> <td><img style="width:50%;" class="img-thumbnail" src="{{obj.photo.url}}" alt="IMG"></td>
<td>{{ obj.title }}</td>
<td>{{ obj.date }}</td>
</tr>
thanks to everyone who was helping.

The image won't show because you didn't put the url in a image html tag.
Modified the template.html file:
...
<td> <img src=/static/{{ obj.photo.url }}></td>
...
Note:'static' should be your STATIC_URL which you set in settings.py.
i found the reason;
in template.py
<tr>
<th scope="row">{{ obj.id }}</th>
THIS CODE SHOULD BE ---> <td>{{ obj.photo.url }}</td>
<td>{{ obj.title }}</td>
<td>{{ obj.date }}</td>
</tr>
<tr>
<th scope="row">{{ obj.id }}</th>

</tr>

Thanks for any help!
You didn't include the path to the view in your form:
<form method="POST" action="/path/to/ta_ranking">
...
</form>
You also need to add it to your urls.py if you haven't already:
from django.urls import path
from myapp.views import ta_ranking
urlpatterns = [
path('/path/to/ta_ranking', ta_ranking),
]
