passing url parameter in django template using form

Question

I'm writing a page that takes an id and finds a user that matches that id. this is the URL pattern that I wrote in urls.py:

re_path(r'^users/id=(?P<username>[0-9]{9})$' , views.usershow , name = 'usershow') ,

I want to pass username using forms and so I wrote this in templates:

<form action="{% url 'CMS:usershow' %}" method="GET" >
{% csrf_token %}
<input name="id" type="number" placeholder="search">
<button type="submit">find</button>
</form>

but it shows me this error :

Reverse for 'usershow' with no arguments not found. 1 pattern(s) tried: ['dashboard/users/id=(?P<username>[0-9]{9})$']

How can I pass it using forms with this URL pattern?

Do you really have to pass {% csrf_token %} when your form method is GET? I think not. — Hassan Baig

@HassanBaig no. I tried post method before that and I forget to delete — Nimdeveloper

That's not how forms work. Remove the username from the pattern:

path(r'^users/' , views.usershow , name = 'usershow') ,

and in the view get the value from the request;

username = request.GET["id"]

First, make sure CMS app's urls.py is having the path.

Second, pass user id value as shown below:

<form action="{% url 'CMS:usershow' user_id %}" method="GET" >
