I trying to open content inside poster using a dynamic url, but I am facing a problem
my code is for a simple web page containing some movie posters and when I click on a poster new template on a new page should open which will show information about this poster.
but whenever I click on a poster same template(index.html) opens in a new page instead of page.html
eg
127.0.0.1:8000/home is web page with all posters and I clicked on poster1 with id=1 then in new page 127.0.0.1/home/1 will open but it is still index.html with all posters, not page.html in which content of poster1 id=1 is stored.
Here is my code
homepage/models.py
from django.db import models
class Poster(models.Model):
poster_name = models.CharField(max_length=20)
poster_img = models.FileField(upload_to="poster_image/")
def __str__(self):
return self.poster_name
class Poster_page(models.Model):
poster = models.ForeignKey(Poster, default= 1)
poster_name = models.CharField(max_length=20)
poster_img = models.FileField()
poster_details = models.TextField()
homepage/views.py
from django.shortcuts import render_to_response
from .models import Poster, Poster_page
def poster(request):
pos = Poster.objects.all()
return render_to_response('index.html', {'pos':pos})
def poster_page(request, id=1):
poster_pg = Poster_page.objects.all()
return render_to_response('page.html', {'poster_pg':poster_pg})
homepage.url
from django.conf.urls import url
from.views import poster, poster_page
urlpatterns = [
url(r'^',poster),
url(r'^home/(?P<id>/d+)/$', poster_page),
]
poster.url
from django.conf.urls import url, include
from django.contrib import admin
from django.conf import settings
from django.conf.urls.static import static
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^home/',include('homepage.urls', namespace='home'))
]
if settings.DEBUG:
urlpatterns += static(settings.STATIC_URL,
document_root=settings.STATIC_ROOT)
urlpatterns += static(settings.MEDIA_URL,
document_root=settings.MEDIA_ROOT)
index.html
<body>
<div class="row">
{% for poster in pos %}
<div class="col-md-4">
<img src="{{ poster.poster_img.url }}" alt="image"><h3>{{ poster.poster_name }}</h3>
</div>
{% endfor %}
</div>
page.html
<body>
<div class="row">
<img src="{{ poster_img.url }}" alt="image"><h2>{{ poster_name }}</h2>
</div>
<div class="row">
<h2>{{ poster_details }}</h2>
</div>
homepage.url
Replace d/+ by \d+
from django.conf.urls import url
from . import views
urlpatterns = [
url(r'^$',views.poster),
url(r'^(?P<id>\d+)/$', views.poster_page),
]
Then Try:
from django.shortcuts import render,get_object_or_404
def poster_page(request, id):
poster_pg = get_object_or_404(Poster_page, id=id)
return render_to_response('page.html', {'poster_pg':poster_pg})
and yes you also need <a href="/home/{{poster.id}}/">.
In index.html you have not defined correct url in href to open poster detail.
Correct syntax would be like this:
<img src="{{ poster.poster_img.url }}" alt="image"><h3>{{ poster.poster_name }}</h3>
I think the issue is in the view with the context variable -
return render_to_response('index.html', {'pos':pos})
should be -
return render_to_response('index.html', {'poster':pos})
Because in you are calling {{poster.id}} in index template.

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::

some of the noticed faults are
context is missing in view, add an empty brackets as shown, which will server as context now, later on you can add key and values reqired
def index(request):
return render(request, 'index.html', {})
fault in indexing url, need to add non over lapping regex patters
path('', views.index, name='index'),
path('feed/', views.feed, name='feed'),
path('upload/', views.upload, name='upload'),
path('messages/', views.messages, name='messages'),
path('statistics/', views.statistics, name='statistics'),
change the url to path as it outdated
path('app/',
view=SendSmsCreateView.as_view(),
name='send_sms'
),
What i did was to add the namespace in the html file
before i used
<a href=" {% url 'feed.html' %} " class="nav-link active">
the above didn't work so i changed it to
<a href=" {% url 'app:feed' %} " class="nav-link active">
I can not figure out what I am doing wrong within the second app my project called 'weather'. The first part, 'home', works fine. I made it so that an empty url '' and a url with '/home/' both map to the home page. Even the link I created in my navigation bar to the home page works, but the same is not true for the weather link. I end up getting 'Page not found 404' Error.
Here is an overview:
Project structure
I included the app 'weather' in the settings installed apps.
Here urls.py file in the main project folder:
from django.contrib import admin
from django.urls import path, include
from weather import views
urlpatterns = [
path('admin/', admin.site.urls),
path('', include('blog.urls')),
path('', include('weather.urls')),
]
The urls.py file for my weather app:
from weather import views
from django.urls import path
urlpatterns = [
path('', views.GetWeather.as_view(), name='weather'),
]
The views.py for the weather app:
from django.views import generic
import requests
from django.shortcuts import render
from .models import City
from .forms import CityForm
class GetWeather(generic.ListView):
queryset = City.objects.order_by('-requested')
template_name = 'weather.html'
def index(request):
url = 'http://api.openweathermap.org/data/2.5/weather?q={}&units=imperial&appid=c5a079de62bccff63d64ac8989f87e37'
form = CityForm()
cities = City.objects.all()
weather_data = []
for city in cities:
r = requests.get(url.format(city)).json()
city_weather = {
'city' : city.name,
'temperature' : r['main']['temp'],
'description' : r['weather'][0]['description'],
'icon' : r['weather'][0]['icon'],
}
weather_data.append(city_weather)
context = {'weather_data' : weather_data, 'form' : form}
return render(request, 'templates/weather.html', context)
The models.py for the weather app:
from django.db import models
from django.contrib.auth.models import User
class City(models.Model):
name = models.CharField(max_length=30)
requested = models.DateTimeField(auto_now_add = True)
class Meta:
ordering = ['-requested']
def __str__(self):
return self.name
class Meta:
verbose_name_plural = 'cities'
The weather.html template:

This is the blog.urls:
from . import views
from django.urls import path
urlpatterns = [
path('', views.PostList.as_view(), name='home'),
path('<slug:slug>/', views.PostDetail.as_view(), name='post_detail'),
]
I greatly appreciate anyone who took the time to read through this and help me.
You will have to change either blogs/urls.py or weather/urls.py first URL match. It depends on what you want to see on your base URL.
# weather/urls.py
from weather import views
from django.urls import path
urlpatterns = [
path('weather/', views.GetWeather.as_view(), name='weather'),
]
# blog/urls.py
from . import views
from django.urls import path
urlpatterns = [
path('', views.PostList.as_view(), name='home'),
path('blog/<slug:slug>/', views.PostDetail.as_view(), name='post_detail'),
]
This shall resolve, assuming you want weather details on first page.
Django Blog APP comes with an out of the box index.html where it shows a list of all posts.
I need to show this list in a new URL, when I somply copy the html code from index.html and paste onto planoacao.html it doesn´t show anything.
This is the index.html:
{% for post in post_list %}
<div class="card mb-4" style="width: 18rem; ">
{% if post.get_finalizado_display == 'Não' %}
<!--<p class="card-text text-muted h6"> NOK </p>-->
<div class="card-body" style="background-color:#FF0909;">
{% else %}
<!--<p class="card-text text-muted h6"> ok </p>-->
<div class="card-body">
{% endif %}
{% endfor %}
This is my views.py:
from django.views import generic
from .models import Post
class PostList(generic.ListView):
queryset = Post.objects.filter(status=1).order_by('-created_on')
template_name = 'index.html'
class PostDetail(generic.DetailView):
model = Post
template_name = 'post_detail.html'
class Calendar(generic.DetailView):
model = Post
template_name = 'calendar.html'
class Planoacao(generic.DetailView):
model = Post
template_name = 'planoacao.html'
This is my urls.py
urlpatterns = [
path('admin/', admin.site.urls),
path('', include('blog.urls')),
url(r'^planoacao/', TemplateView.as_view(template_name="planoacao.html")),
url(r'calendar', TemplateView.as_view(template_name="calendar.html")),
url(r'^admin/', admin.site.urls),
url(r'^', include('blog.urls'), name="Blog"),
] + static(settings.MEDIA_URL, document_root = settings.MEDIA_ROOT)
How can I show a list of all posts in a different URL? xxx/planoacao.html ? Simply copying the html from index.html doesn´t work.
Note that I don´t want to change the regular index.html post list, I just want to add a second post list page.
It seems you want to show your PostList view at /planoacao, so in urls.py you can hook this path up to that view:
url(r'^planoacao/', PostList.as_view()),
Note that in Django there is no direct link between the path of a view and the template used. You can use any template with any path, all you have to do is define which template to use in the view.
If i have a url that is "someurl/report/1/" where "report" is an app and "1" corresponds to a certain id of a model in my SQL database, how would i substitute the variables in the template with that specific models data?
In my case I am writing a website that displays a surf report for different beaches. I have set it up so each SQL model id corresponds to a different beach. So if I wanted to use the data of beach "3" in the template, how would i display those in the html template?
TRACEBACK
Using the URLconf defined in surfsite.urls, Django tried these URL patterns, in this order:
^admin/
^report/ ^$ [name='index']
^report/ (?P[0-9]+)$ [name='get_report']
The current URL, report/1/, didn't match any of these.

#MY MODEL
from __future__ import unicode_literals
from django.db import models
class Beach(models.Model):
name = models.CharField(max_length=50)
high = models.SmallIntegerField()
low = models.SmallIntegerField()
wind = models.SmallIntegerField()
tide = models.DecimalField(max_digits=3, decimal_places=2)
def __str__(self):
return self.name
#MY VIEWS
from django.http import Http404
from django.shortcuts import render
from .models import Beach
def index(request):
allBeaches = Beach.objects.all()
context = {
'allBeaches': allBeaches,
}
return render(request, 'report/index.html', context)
def get_report(request, id):
try:
beach = Beach.objects.get(id=id)
except Beach.DoesNotExist:
raise Htpp404("404")
return render(request, 'report/index.html', {'beach': beach})
If i understand you right, you want to create view, that render beach separately
You can do something like this, your view:
def get_beach(request, id)
beach = Beach.objects.get(id=id)
return render(request, 'path/to/your/template', {'beach':beach})
urls:
url(r'^someurl/report/(?P<id>[0-9]+)$', views.get_beach(), name='get_beach'),
template url to this page:
beach
Edited
Its your view, as i understand, this is detail view, but select all objects(Break.objects.all())
def detail(request, break_id):
try:
allBreaks = Break.objects.all()
except Break.DoesNotExist:
raise Http404("404")
return render(request, 'report/index.html', {'allBreaks': allBreaks})
so you have to change this on this:
def detail(request, break_id):
try:
break_detail = Break.objects.get(id=break_id)
return render(request, 'path/to/your/template', {'break_detail':break_detail})
except Break.DoesNotExist:
raise Http404("404")
then your url should look like this:
url(r'^someurl/report/(?P<break_id>[0-9]+)$', views.detail(), name='detail'),
or you can use get_object_or_404:
def detail(request, break_id):
break_detail = get_object_or_404(Break, id=break_id)
return render(request, 'path/to/your/template', {'break_detail':break_detail})
Url is the same.
So if you want to access to wind field, you just write this tempalte tag {{break_detail.wind}}
UPD2
change place from this
^admin/
^report/ ^$ [name='index']
^report/ (?P<beach_id>[0-9]+)$ [name='get_report']
to this:
^admin/
^report/(?P<beach_id>[0-9]+)$ [name='get_report']
^report/^$ [name='index']
and delete spaces in urls after report/
