Django view gets unexpected keyword argument

I tried get the id from my database and make something like /article/1/. 1 is the id of my article but it didn't work.

views.py

def article(request, article_id):
    return render_to_response('article.html', {{'article': Articles.objects.get(id=article_id)}})

my urls.py

from django.urls import path, re_path

from . import views

urlpatterns = [
    path('showall/', views.articles, name='articles'),
    path('<int:article_id>/', views.articles, name='article'),

]

I get the error:

TypeError at /article/1/ articles() got an unexpected keyword argument 'article_id'

I also include image of my datebase

You are using views.articles in article/id/ url which most likely you have used for article/showAll/ url. Use this instead:

path('<int:article_id>/', views.article, name='article')

It looks as if you are using views.articles for the article detail view:

path('<int:article_id>/', views.articles, name='article'),

You should use views.article instead:

path('<int:article_id>/', views.article, name='article'),

Note that there are a few improvements/fixes you can make to your article view:

  • Use get_object_or_404 so that you don't get a server error when the article does not exist in the database
  • Use render instead of the obsolete render_to_response
  • The context dictionary should be a dictionary {...}. You currently have double curly brackets {{...}}

Putting that together you get:

from django.shortcuts import get_object_or_404, render

def article(request, article_id):
    article = get_object_or_404(Article, id=article_id)
    return render(request, 'article.html', {'article': article})

Your views.py defines an article function while your urls.py makes use of an articles (note the plural) function. Is this a typo, or is there any articles function in views.py that does not support an optional article_id parameter?
