How to use Django's built-in template tags for URL handling

Django provides several built-in template tags for handling URLs in templates. These tags make it easier to generate URLs for your views and handle dynamic content. Here are some of the commonly used template tags for URL handling in Django:

1. {% url 'view_name' arg1 arg2 %}: This tag is used to reverse-resolve a URL based on the view name and any arguments it may have. For example:

   htmlCopy code
   <a href="{% url 'app_name:view_name' arg1 arg2 %}">Link Text</a>
   

   Replace 'app_name' with the name of your Django app, 'view_name' with the name of your view, and provide any necessary arguments.

2. {% url 'namespace:view_name' arg1=arg_value %}: If you're using URL namespaces, you can include the namespace in the tag like this:

   htmlCopy code
   <a href="{% url 'namespace:view_name' arg1=arg_value %}">Link Text</a>
   

3. {% with variable_name=arg1|filter %}: You can use the with tag to create a variable that holds a filtered value, and then use that variable in the url tag. For example:

   htmlCopy code
   {% with arg1|filter as filtered_arg %}
       <a href="{% url 'app_name:view_name' filtered_arg arg2 %}">Link Text</a>
   {% endwith %}
   

4. {% if request.GET.param %}: You can use the if tag to conditionally render content based on the presence of query parameters. For example:

   htmlCopy code
   {% if request.GET.param %}
       <p>Parameter exists in the URL!</p>
   {% endif %}
   

5. {% if request.path == '/desired/path/' %}: You can use the if tag to check the current path and render content conditionally. For example:

   htmlCopy code
   {% if request.path == '/desired/path/' %}
       <p>This is the desired path!</p>
   {% endif %}
   

Remember to load the {% load static %} tag at the top of your template if you want to use the {% static %} tag for handling static files.

These are just a few examples, and Django provides more template tags for working with URLs. Refer to the official Django documentation on template tags for more details and options.
