Download HTML This will request the html code from a website. We can use fetch() or jquery or any other available method to make an AJAX request. After calling this, we have the file data in a Python variable of type string. Instead of using a template tag, we can also create an end-point and make an AJAX request to that end-point to perform some task or get some data. decode() converts it to a string using Unicode UTF-8 decoding rules. Note that it is important to first load a module with custom template tags before using those template tags. .read() first downloads the data in binary format, then. Once the module is loaded, we can now use the template tags defined inside the my_custom_tags module. We first load the my_custom_tags.py module inside the template. Now that we have created our first template tag, it is time to load it inside our HTML template and use it.We can create even more template tags here to perform specific and common tasks. This template tag will return "Hello World from my_tag() custom template tag." this string to the template. As shown in the code above, my_tag is a custom template tag that we just created and now it can be used inside any HTML template. My_custom_tags.py module will hold all the custom template tags. Return "Hello World from my_tag() custom template tag." Inside this file, add the following code.Inside the templatetags folder, create a Python file named my_custom_tags.py.The app directory should look something like this.

The output will remain the same, as shown above. There are no restrictions on allowed values, and the browser will automatically detect the correct file extension and add it to the file (.img. The value of the attribute will be the name of the downloaded file. Now, the Python script will look as follows. The download attribute is only used if the href attribute is set.
