the app worked fine before I added the <a href= on the image in index.html.
Can't figure out what's wrong.
This indicates the problem.
'$(?P<pk>[0-9]+)/$'
There shouldn't be a dollar sign (which matches the end of the string) at the beginning of the pattern.
The problem is caused by the way you are including the urls.py. You currently have a dollar in the regex:
url(r'^$', include('feature.urls', namespace="feature")),
To fix the problem, remove the dollar from the regex.
url(r'^', include('feature.urls', namespace="feature")),

The 'tractor' part in the path('', include(('tractor.urls', 'tractor'))) in the include(…) function [Django-doc] specifies the app_namespace. This means that for all URLs you use in the tractor.urls urls, you should prefix this with tractor::
<a href="{% url 'tractor:post-detail-page' slug=post.slug %}">

I'm new to Django and I'm making wiki website based on markdown. I am having one problem. Django can't match the path in html to urls.py. It happens when I try to open wiki entries. It gives me the following error. I have already passed the parameter to 'page', I honestly have no idea what to do.
Using the URLconf defined in wiki.urls, Django tried these URL patterns, in this order:
admin/
[name='index']
wiki/<str:page> [name='page']
search [name='search']
create [name='create']
addentry [name='add_entry']
nomatches [name='nomatches']
results [name='results']
edit/<str:page> [name='edit']
random [name='random']
The current path, { url 'page' entry }, didn't match any of these.
Please, tell me how can I fix this.
index. html:
{% extends "encyclopedia/layout.html" %}
{% block title %}
Encyclopedia
{% endblock %}
{% block body %}
<h1>All Pages</h1>
<ul>
{% for entry in entries %}
<li>{{ entry }}</li>
{% endfor %}
</ul>
{% endblock %}
urls.py
from django.urls import path
from . import views
urlpatterns = [
path("", views.index, name="index"),
path("wiki/<str:page>", views.viewpage, name="page"),
path("search", views.search, name="search"),
path("create", views.create, name="create"),
path("addentry", views.add_entry, name="add_entry"),
path("nomatches", views.search, name="nomatches"),
path("results", views.search, name="results"),
path("edit/<str:page>", views.edit, name="edit"),
path("random", views.random, name="random")
]
part of views.py:
def index(request):
return render(request, "encyclopedia/index.html", {
"entries": util.list_entries()
})
def viewpage(request, page):
content = util.get_entry(page)
return render(request, "encyclopedia/page.html", {
"content": markdown2.markdown(content),
"title":page
})
page.html
{% extends "encyclopedia/layout.html" %}
{% block title %}
{{ title }}
{% endblock %}
{% block body %}
edit
<h1>{{ title }}</h1>
{{ content|safe }}
{% endblock %}
Since the URL for 'page' is 'wiki/<str: page>' you need to define a get_absolute_url method on your class model that contains the object in question, so do add this method in the models.py class that contains page:
def get_absolute_url(self):
return reverse('page',kwargs={str:self.str})
Then, in the template, you can refer to it as
{% object.get_absolute_url%}.
when i run my code (its for a project) i get this error: "no such table: encyclopedia_article". The error appears to come from 9 line of views.py (obj = article.objects.get(id=1). here is the code:
