I Keep Getting This Error,  
As i learn about the error it appears when i pass slug incorrectly into `urls` or into `views`.  
and i am using `DetailView`.

Views:

```auto
class ClientDetailView(DetailView):
    model = Account
    context_object_name = 'account'
    template_name = 'Accounts/Client_Info.html'

    def get_context_data(self, **kwargs):
        context = super(ClientDetailView, self).get_context_data(**kwargs)
        account = Account.objects.get(slug=self.kwargs['slug'])
        context['account'] = account
        context['page'] = account.full_name
        return context

```

Urls: I Used This

```auto
path('client-detail/<slug>', views.ClientDetailView.as_view(), name='ClientDetailUrl'),

```

or this too

```auto
path('client-detail/<slug:slug>', views.ClientDetailView.as_view(), name='ClientDetailUrl'),

```

HTML:

```auto
<a href="{% url 'Accounts:ClientDetailUrl' account.slug %}">{{ account.full_name }}</a>

```

or

```auto
<a href="{% url 'Accounts:ClientDetailUrl' slug %}">{{ account.full_name }}</a>

```

or

```auto
<a href="{% url 'Accounts:ClientDetailUrl' slug=account.slug %}">{{ account.full_name }}</a>

```

any idea i will be thankful for

One of the easiest ways to verify that you’re getting the data in the template that you’re expecting to see is to replace the `a` tag with just a simple display of the value that you’re using.

In this case, you can replace:

> [@AhmdMWddh](#):
>
> `<a href="{% url 'Accounts:ClientDetailUrl' account.slug %}">{{ account.full_name }}</a>`

with:  
`## {{ account.slug }} ## {{ account.full_name }} ##`  
You won’t get a link, but you’ll get the data being found displayed directly on the page, avoiding the error message.

(Also, it helps if you post the complete error message and not just a summary.)

Full Error:

```auto
Reverse for 'ClientDetailUrl' with arguments '('',)' not found. 1 pattern(s) tried: ['accounts/client\\-detail/(?P<slug>[^/]+)\\Z']

```

I found the problem within `account object`  
it works as `request.user` but `account` does not working.  
i tried to print account on DetailView but i also did not work.  
Note:  
this works.

```auto
<a href="{% url 'Accounts:ClientDetailUrl' request.user.slug %}">{{ request.user.full_name }}</a>

```

What is the view that is generating the page that is trying to render this link? _That_ is the view we need to see.

This View

Ok, so to confirm, this line:

> [@AhmdMWddh](#):
>
> `<a href="{% url 'Accounts:ClientDetailUrl' account.slug %}">{{ account.full_name }}</a>`

is in the file named `Accounts/Client_Info.html`, which is being rendered in a view named ClientDetailView - so in other words, you’re linking the page to itself.

How are you navigating to that page?

I dont think i did understand that,  
but i can confirm this  
this link goes to the account page when click,

it use this Url to get the account slug

```auto
<a href="{% url 'Accounts:ClientDetailUrl' account.slug %}">{{ account.full_name }}</a>

```

which use the View

```auto
class ClientDetailView(DetailView):
    model = Account
    context_object_name = 'account'
    template_name = 'Accounts/Client_Info.html'

    def get_context_data(self, **kwargs):
        context = super(ClientDetailView, self).get_context_data(**kwargs)
        account = Account.objects.get(slug=self.kwargs['slug'])
        context['account'] = account
        context['page'] = account.full_name
        return context

```

to render HTML page in Folder Accounts in Templates folder with name `Client_Info.html`

I don’t care about what that link is referring to.

I’m only concerned about the view and page that first takes you to ClientDetailView.

What is the page / view that you are looking at when you click on something to take you to ClientDetailView?

What does your Account model look like?

Is this the _complete_ view? (Have you overridden any other methods in that class?)

We may need to see the complete template as well.

I’m still confused here.

This Navbar template, is _this_ the template file containing the `a` tag that is causing the error?

If so, how are you **first** getting to _any_ page that is rendering this template?

Yes, navbar have this tag causing error

this is home view that render home page if it has any information will be useful

```auto
class HomeView(TemplateView):
    template_name = 'Home.html'

    def get_context_data(self, **kwargs):
        context = super(HomeView, self).get_context_data(**kwargs)
        context['page'] = 'Home'
        return context

```

but i think the error in `ClientDetailView`  
i think it does not get the account object, because this error not showing when i am using `request.user` instead of `account`.

The issue is that your HomeView is trying to render that template without providing anything in the context for the `account` that the tag is trying to reference. There may still be a problem in ClientDetailView, but that would be a different issue.

You’re passing an Account in _that_ view to your context, but you are not supplying an Account object _here_.
