Hi all,
-- i am having issue with url tag, every time i put url tag like --{% url 'productsgrouping' item.id%}-- i get no reverse error.
Can you help me figure it out on what am i doing wrong?
view:
def productsgrouping_view(request):
queryset = MaterialGroup.objects.all()
context = {"list" : queryset}
return render(request, 'qif/productsgrouping/productsgroup.html', context)
def productsgrouping_update_view(request, url_id):
product_lista = MaterialGroup.objects.get(id=url_id)
product_url_id = ProductgroupinputForm(request.POST or None, instance=product_lista)
context1 = {'product_url_id': product_url_id, 'product_lista': product_lista}
if product_url_id.is_valid():
product_url_id.save()
return render(request, 'productsgroup-update.html', context1)
url:
urlpatterns = [
path('', views.productsgrouping_view, name='productsgrouping'),
path('update/<int:url_id>/', views.productsgrouping_update_view, name='update_productsgrouping'),
path('new/', views.creategroup_view, name='create_group'),
]
html:
{% extends 'base.html' %}
{% block content %}
<ul >
{% for item in list %}
<h1>
<a href="{% url 'productsgrouping' item.id%}"></a>
{{ item }} - {{item.id}}
</h1>
{% endfor %}
{% endblock %}
