Django unique URL redirection issue

Question

Having issues trying to redirect after from submission to edit more fields Also with creating the hyperlink to the submission.

When submitting my form with the redirect i get the error below. If i submit the form with the render request to another page the form saves ok.

Request Method: POST Request URL: http://127.0.0.1:8000/resourcelib/add_pricebook Django Version: 1.8.4 Exception Type: NoReverseMatch Exception Value: Reverse for 'detail_pricebook' with arguments '()' and keyword arguments '{'p_id': 22L}' not found. 0 pattern(s) tried: []

My Model.py

class PriceBook(models.Model):
    pricebook_id = models.AutoField(primary_key=True)
    pricebook_name = models.CharField(max_length=255,verbose_name='PriceBook Name')
    discription = models.TextField(verbose_name='Discription')
    date_created = models.DateTimeField(auto_now_add=True, blank=True)
    active = models.SmallIntegerField(max_length=1, blank=True)

    def __unicode__(self):
        return self.pricebook_name

view.py

 def new_pricebook(request):
    if request.method == "POST":
        pricebook_form = PricebookForm(request.POST)
        if pricebook_form.is_valid():
                post = pricebook_form.save(commit=False)
                post.save()
                #return render(request, 'resourcelib/thanks.html',)
                return redirect('detail_pricebook', p_id=post.pricebook_id)

    else:
        pricebook_form = PricebookForm()
        return render(request, 'resourcelib/pricebook_add.html', {'pricebook_form': pricebook_form})

def detail_pricebook(request, p_id):
    pricebook_from = get_object_or_404(PriceBook, pk=p_id)
    return render(request, 'resourcelib/pricebook_detail.html', {'pricebook_from':pricebook_from})

url.py

url(r'^add_pricebook', views.new_pricebook, name='new_pricebook'),
    url(r'^list_pricebook', views.list_pricebook, name='list_pricebook'),
    url(r'^detail_pricebook/(?P<p_id>[0-9]+)/$', views.detail_pricebook, name='detail_pricebook'),

I don't believe it's in url file, because i get no errors if i browse to the entry eg. 127.0.0.1:8000/resourcelib/detail_pricebook/3/ - works ok

However i can't get my links working either, i can list my entries ok. But the link won't work from the code below when you click on the link it just comes up 127.0.0.1:8000/resourcelib/%7B%%20url%20'detail_pricebook'%20p_id.pk%7D

{% if pricebooks %}
    <ul>
    {% for pricebook in pricebooks %}
        <li><h1><a href="{% url 'detail_pricebook' p_id.pk}">{{ pricebook.pricebook_name }}</a></h1></li>
    {% endfor %}
    </ul>
{% else %}
    <p>No price books have been created.</p>
{% endif %}
{% endblock %}

Any help would be greatly appreciated

Answer 1

% missing in the url tag. Be more careful.

Answer 2

thanks @ozgur, have the the idea that i have the wrong reference for the pk. I was able to sort out the issue. I had a name name space on the primary project urls.py ... probably information i should have give, forgot I used cookiecutter for this one

url(r'^resourcelib/', include('oneworksite.resourcelib.urls', namespace='resource')),

so i was then able to get the link working with

<a href="{% url 'resource:detail_pricebook' pricebook.pk %}">{{ pricebook.pricebook_name }}</a>

Then in my redirect i changed to return redirect('resource:detail_pricebook', p_id=post.pk)
