Have looked through a lot of similar NoReverseMatch Errors and couldn't solve my problem. This is in Django.
I keep getting: NoReverseMatch at /equipment32 Reverse for 'equipment' with arguments '('', 32)' not found. 1 pattern(s) tried: ['equipment(?P<equipment_id>[0-9]+)$']
Here is the traceback:

This is my template, job.html, that generates the links:
<table style="width: 900px">
<caption style="font-size: 25px">Equipment in Scope</caption>
<a href="#equipment_form" style="font-size: 20px">Add Equipment</a>
<tr>
<th>Site ID</th>
<th>Equipment Type</th>
<th>Manufacturer</th>
<th>Model</th>
<th>Test Sheet</th>
</tr>
{% for equipment in equipments %}
<tr>
{% csrf_token %}
<td><a href="{% url 'equipment' equipment.id %}">{{equipment.site_id}}</a></td>
<td>{{equipment.template.classification}}</td>
<td>{{equipment.manufacturer}}</td>
<td>{{equipment.model}}</td>
<td><a href="www.drive.google.com">Test Sheet</td>
</tr>
{% empty %}
<li>No Equipment</li>
{% endfor %}
</table> <br>
This seems to load fine and create links for each equipment object. Here's my urls.py:
from django.urls import path
from . import views, constructors
from .models import Job, FSR, Template, Equipment, TestEquipment
urlpatterns = [
path("equipment<int:equipment_id>", views.equipment, name="equipment"),
]
This url is supposed to link to views.equipment; here it is:
from django.contrib.auth import authenticate, login, logout
from django.contrib.auth.forms import UserCreationForm
from django.shortcuts import render, redirect
from django.http import HttpResponse, Http404, HttpResponseRedirect
from django.urls import reverse
from .models import Job, FSR, Template, Equipment, TestEquipment
def equipment(request, equipment_id):
if not request.user.is_authenticated:
return render(request, "jobs/login.html", {"message": None})
try:
equipment=Equipment.objects.get(pk=equipment_id)
except Equipment.DoesNotExist:
raise Http404("Equipment does not exist.")
context = {
"equipment": equipment,
"templates": Template.objects.all(),
"test_equipments": equipment.template.recommended_test_equipment.all(),
}
if request.user.is_authenticated:
return render(request, "jobs/equipment.html", context)
which should generate my actual equipment.html:
{% extends "jobs/base.html"%}
{% block title %}
{{equipment.site_id}}
{% endblock %}
{% block body %}
<h1 style = "text-align: center">{{equipment.site_id}} ({{equipment.template.classification}})</h1>
<style>table, th, td {
border: 1px solid black;
border-collapse: collapse;
}</style>
<table style="width:900px">
<caption style="font-size: 25px">Equipment Properties</caption>
<tr>
<td>Equipment Type</td>
<td><b>{{equipment.template.classification}}</b></td>

<tr>
<td>Job Site ID or Name</td>
<td><b>{{equipment.site_id}}</b></td>

</tr>
<tr>

<input type="reset"></b></a></td>
</form> -->
</tr>
<tr>
<td>Scope for This Equipment</td>
<td><a><b>{{equipment.scope}}</b></a></td>
</tr>
<tr>
<td>Additional Notes</td>
<td><a><b>{{equipment.notes}}</b></a></td>
</tr>
</table><br>
<h3>Recommended Test Equpiment</h3>
<ul>
{% for test_equipment in test_equipments %}
<li>
{% csrf_token %}
{{ test_equipment }}
</li>
{% empty %}
<li>No Equipment</li>
{% endfor %}
</ul>
<button onclick="goBack()">Back to Job Page</button>
<script>
function goBack() {
window.history.back();

I don't understand why it seems to be asking for two arguments equipment("", 35) because the views function only takes in equipment_id. Any help is very greatly appreciated!
in your template equipment.html you provided two argument just remove job.id. though it is commented but it should be proper urlpattern
<form action="{% url 'equipment' equipment.id%}" method="post">
<td><a><b><textarea id="scope" name="scope" rows="4" cols="55" >{{ equipment.equipment_answers }}</textarea><input type="submit" value="Confirm Answers">
<input type="reset"></b></a></td>
</form>
