HI working on a new site using Django. can’t seem to figure this bug out. First the intended site will be structured as;
Home page - Showing different languages with links to countries you can learn those languages in. Click on a country on home page → Country page Country page will list all fo the schools that teach that language in that country. Click on a school on country page → School page.
I figured out this line of code in the Country page is causing the issue, but I don’t know how to fix it
<a href="{% url 'schools' country_id=country.id schools_id=schools.id %}">
<div class="left"><h4>Test Link</h4></div>
</a>
This is the error I get in the browser
NoReverseMatch at /5/ Reverse for ‘schools’ with arguments ‘(’’,)’ not found. 1 pattern(s) tried: [’(?P<country_id>[0-9]+)/(?P<schools_id>[0-9]+)/
Code from the project: Models.py
from django.db import models
class Languages(models.Model):
language = models.CharField(max_length=100, blank=True, null=True)
country = models.ManyToManyField('Country', blank=True)

urls.py
from django.contrib import admin
from django.urls import path
from schools import views
urlpatterns = [

path('', views.home, name='home'),

Any help would be greatly appreciated. Also please forgive any mistakes in posting or coding, still very new to coding/ life in general
