I’m trying to implement inline editing feature using HTMX in Django form. I’ve checked the url routing several times and am pretty sure, that everything should be correct.

I’m gettings django.urls.exceptions.NoReverseMatch: Reverse for 'update_work_hours' with arguments '('',)' not found. 1 pattern(s) tried: ['nuomotojo\-platforma/darbo\-laikas/atnaujinti/(?P<pk>[0-9]+)/\Z'] error while executing get request.

Template (delete works perfectly fine, so I assume, that hours.pk is passed correctly):

<div id="work_hour_day" class="flex flex-col md:flex-row items-center my-2">
        <span>{{ hours.get_day_of_week_display }}: {{ hours.opening_time }}-{{ hours.closing_time }}</span>
        <div class="flex gap-2 mx-2">
          <button hx-get="{% url 'rentals:update_work_hours' hours.pk %}" hx-target="closest #work_hour_day" hx-swap="outerHTML" class="text-white bg-blue-700 hover:bg-blue-800 focus:ring-4 focus:ring-blue-300 font-medium rounded-lg text-sm px-5 py-2.5 dark:bg-blue-600 dark:hover:bg-blue-700 focus:outline-none dark:focus:ring-blue-800">Keisti</button>
          <button hx-delete="{% url 'rentals:delete_work_hours' hours.pk %}" hx-target="closest #work_hour_day" hx-swap="outerHTML swap:1s" hx-trigger='confirmed' onClick="Swal.fire({title: 'Confirm', text: 'Do you want to continue?', icon: 'question'}).then((result)=>{
            if(result.isConfirmed){
              htmx.trigger(this, 'confirmed');  
            } 
        })" class="focus:outline-none text-white bg-red-700 hover:bg-red-800 focus:ring-4 focus:ring-red-300 font-medium rounded-lg text-sm px-5 py-2.5 dark:bg-red-600 dark:hover:bg-red-700 dark:focus:ring-red-900" type="button">Ištrinti</button>
        </div>
</div>

        day_of_week = working_hours.get_day_of_week_display()
        # If request from cancel button in the form, return the initial data
        trigger = request.headers.get("HX-Trigger")

Urls.py:

path(

    ),

Several times I went through all the details, so that I would not miss a letter or something like that. Also went through it with ChatGPT. It can’t find anything specific.
