Tutorial writing views help

[Kareem Hart]

I am currently up to the "writing views" part of the tutorial and just wrote the polls/index.html template. I updated the view in polls/view.py as such:

from django.http import HttpResponse

from django.template import loader

from .models import Question

def index(request):

    latest_question_list = Question.objects.order_by('-pub_date')[:5]

    template = loader.get_template('polls/index.html')

    context = {

        'latest_question_list': latest_question_list,

    }

    return HttpResponse(template.render(context,request))

def detail(request,question_id):

    return HttpResponse("You're looking at question %s." % question_id)

def results(request,question_id):

    response = "You're looking at the results of question%s."

    return HttpResponse(response % question_id)

def vote(request,question_id):

    return HttpResponse("You're voting on question %s." % question_id)

I ran  $python manage.py check and the system identified no issues.

When I open the page 127.0.0.1:8000/polls/ I  get a blank page instead of a bulleted list of the questions I created.

Also I get the following error when I load 127.0.0.1:8000/polls/.

Page not found (404)

Request Method:	GET
Request URL:	http://127.0.0.1:8000/

Using the URLconf defined in mysite.urls, Django tried these URL patterns, in this order:

1. ^polls/
2. ^admin/

The empty path didn't match any of these.

mysite.urls

from django.conf.urls import url, include

from django.contrib import admin

urlpatterns = [

    url(r'^polls/', include('polls.urls')),

    url(r'^admin/', admin.site.urls),

]

Hi Kareem,

Regarding the 404 page error, you do not have to put a dot (.) at the end of your URL. Django does not have such kind of a pattern match in your urls. 127.0.0.1:8000/polls/ is the correct URL. Having said that, how does your index template look like? It might be that you are getting a blank page because you are not declaring your variables correctly in the template itself. Meaning it might not be specifically a Django back-end error but a front-end html (template) error. Have a look at your template variables and tags and see if your data is correctly being presented to the template. You will need some code like:

{% if latest_question_list %}
{% for question in latest_question_list %}

 Have a look at the template documentation for details.

Here is my template.

 

index.html

{% if latest_question_list %}

    <ul>

    {% for question in latest_question %}

        <li><a herf="/polls/{{question.id}}/">{{question.question_text}}</a></li>

    {% endfor %}

    </ul>

{% else %}

    <p>No polls are available.</p>

{% endif %} 

Here is my command prompt log.

I've found my mistake with the index.html file.

  {% for question in latest_question %}

        <li><a herf="/polls/{{question.id}}/">{{question.question_text}}</a></li> 

herf is suppose to be href.

But  http://127.0.0.1:8000/  still says page not found.

[Matthew Pava]

And are you navigating to

http://127.0.0.1:8000/polls/

?  

 

I don’t think you should have anything at

http://127.0.0.1:8000/  

or so it seems.

Hi Kareem,

In your template you have your code as: 

{% for question in latest_question %}

According to your context dictionary in your index view, the above template code should be:

{% for question in latest_question_list %}

And then you should go to the url 127.0.0.1:8000/polls/

Regards.
