A što ne uradiš update preko class based view daleko je lakše?

https://docs.djangoproject.com/en/2.1/ref/class-based-views/generic-editing/

Ako hoćeš preko funkcije ja radim sa get_object_or_404, ovako:

def productsgrouping_update_view(request, url_id):

product_lista = get_object_or_404(MaterialGroup, pk=url_id)

Hi  Andréas,

sorry for misspeling in codes. All is working ok except when i try to put url tag for 'update_productsgrouping'. 

I need to update group with new products but It does not argument for group id.

What do you think i am doing wrong...?

Hi, 

The reason you are getting this is that you are adding an argument to the productsgrouping url - which doesn't take any arguments. 

In your code you have: 

<a href="{% url 'productsgrouping' item.id%}"></a>

(Which by the way isn't correct either, I think you mean: <a href="{% url 'productsgrouping' item.id%}">{{ item }} - {{item.id}} </a>)

If you look at the url for the producsgrouping view, you have:

path('', views.productsgrouping_view, name='productsgrouping'),

Which doesn't take any arguments, when you then add an argument django can't find the right URL.

You may mean: 

<a href="{% url 'update_productsgrouping' item.id%}">{{ item }} - {{item.id}} </a>

?

Regards,

Andréas

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 %}
