Error during template rendering django

Don’t understand the point where i’m missing.

In urls.py, is that path() in the urlpatterns assignment?
‘’’

Are there any other patterns in urls.py?

yes it is in urlpatterns.

May be you can get something from Traceback Message:

Is urls.py the one in the project folder, or is it in /blogs? If it’s in the app, can we please see your root urls.py?

it’s the blog app folder not the root folder.
root folder code is:

It seems that you’re including the blog/urls.py in the project with a namespace. In that case, the reverse would be namespace:view name, or in your case, blog:login. Try that in your template inside the url tag and see if that works.

Ok so got that fixed thanks a lot. just a newbie problem. but the learning was good. i forgot about the namespace.

The first time I had that happen, it took me HOURS to figure it out. Glad I could help!

can you please send a screenshot of your fixed code? im having the same issue

Can you put your template code here. Main problem is there only. The reverse would be namespace:view in template rendering.

Thank you! This is the answer I was looking for aswell,

I was searching for this!! you’ve solved my issue!! thank you so much!!

this is my project urls.py

and here is the blog app urls.py

i’m still getting this error…
Reverse for ‘blog-home’ not found. ‘blog-home’ is not a valid view function or pattern name.
Any kind of help will be highly appreciated.

In the project urls.py, you have this:

(snipped the remainder for brevity’s sake)

The namespace is added to the front of the reverse. I don’t know if one is allowed to have a colon in the namespace, as I’ve never tried that. I would write this as so:

Which makes the reverse for the ‘’ path as blog:blog-home. What does your template where this error comes up look like?

This is the correct answer. I thought it was optional to add the namespacing to a url tag especially because I had only one application. Thanks

the same mistake question，info is…

Can someone help? What should I do?
Or … Or what information should I give less? PLZ…

Somewhere in a view or template you’re attempting to reverse a url named ‘store’. You can try ‘store:store’. If that doesn’t work, we’ll need to see the view or template that is generating this error.

return render(request, ‘store/store.html’, context)

you say mean is —> return render(request, <>, context).
or —> return render(request, “store:store”, context).

I have tried both of these methods, but this problem will evolve in the future, but there are no errors in my program, and running out of the dict makes me a little puzzled QWQ

Attach the link to the result after the operation: https://paste.ubuntu.com/p/TJKWBBwSTc/

How to write
return render(request,‘store/cart.html’, context) .

1.return render(request,‘store: store’, context)
or
2.return render(request, <>, context)
I have tried both of these methods, but this problem will evolve in the future, but there are no errors in my program, and running out of the dict makes me a little puzzled QWQ

Attach follow-up results:

sorry for bothering,

1. Add app_name =‘store’ in urls.py ->

Then in my views.py,
def store(request):
data = cartData(request)

—-> return render(request, <>, context)
—-> return render(request, <>, context)
—-> return render(request, <>, context)

<> After this is used,
This message is produced Exception Value: unhashable type:‘dict’

Excuse me, is this <> wrong? Someone uses something like this? Or there are keywords that allow me to query django. I really don’t see these things in the django data. QWQ also rarely sees people using this way. Can they give me similar knowledge? ?

1. If I “do not” do this <><><>, enter the shopping cart http://127.0.0.1:8000/store/cart/ will produce This error occurred: Reverse for’store’‘cart’‘checkout’ not found.‘store’ is not a valid view function or pattern name.

Then very unexpectedly, there is no error in def store, def cart(request):, the problem is the dict in the cart

Picture two and three are the same,
Is it a symbol problem in the () [] <> def cart() program?
def cart(request):
data = cartData(request)

<> -> It is impossible to change django to [[ ]] (()) like this R… strange QWQ

Thank you in advance

CAN visit views.pt.py

from django.shortcuts import render

cartItems = data[‘cartItems’] # cartItems = cookieData[‘cartItems’]
order = data[‘order’] # order = cookieData[‘order’]
items = data[‘items’] # items = cookieData[‘items’]

ключевая ошибка в Django. Во время рендеринга шаблона

Извините, если это нубский код или вопрос. Я делаю нумерацию страниц с использованием django-pagination, и я делаю это так. Но это дает мне keyError на моей странице, кроме того, он упоминает, что это ошибка во время рендеринга шаблона. Что я делаю не так здесь. Я успешно установил нумерацию страниц, изменил файл settings.py. Но я не знаю, что мне нужно делать здесь. Любая помощь будет высоко оценен.

Подробная информация о трассировке вставлена здесь http://dpaste.com/919526/

Код вида следующий

Views.py

Def active_user_table (request, b): if request.method! = «GET»: поднять Http404

Извините, я не использую django ORM на данный момент, но я сделаю это в будущем.

Я решил это сам, но благодаря ndpu за помощь по крайней мере, я убедился, что не было никакой другой проблемы, кроме некоторых проблем с настройками. В этом вопросе у меня проблемы с настройкой django-pagination. Alasdair упомянул добавление «django.contrib.auth.context_processors.auth» в TEMPLATE_CONTEXT_PROCESSORS. Просто добавив его, я получаю правильные ожидаемые значения.

Для тех, кто использует ярлык рендеринга и все еще сталкиваясь с этой ошибкой, просто добавьте <‘request’:request>в переменную контекста

Вы должны добавить context_instance в вызове render_to_response:

Или вы можете использовать кортеж TEMPLATE_CONTEXT_PROCESSORS в файле settings.py. Добавьте эту строку «django.core.context_processors.request» к процессорам контекста, и каждый RequestContext будет содержать запрос переменной.

Я тоже сталкиваюсь с этой ошибкой ранее. Я получил следующую ошибку: Внутренняя ошибка сервера: / cancel-email /

Я попробовал некоторые решения Google, но не смог решить, затем, наконец, снова проверил мой код и обнаружил глупую ошибку в файле шаблона.
