How to get file name of current template inside Jinja2 template?

Say I use return render_template('index.html', users=users). Is it possible to get the filename inside a template without explicit sending of it inside the view?

Although undocumented, {{ self._TemplateReference__context.name }} will give the template name. And there are a number of interresting attributes that you can use after self._TemplateReference__context.

You could, for example, add this to your topmost base template:

        <meta name="template" content="{{ self._TemplateReference__context.name }}">

So that looking at a page source will help you quickly find the relevant template file. If you don't want to expose this kind of information, make it conditional to testing environment.

If all you need is the basename, you can use {{ self }} which will return a repr string containing the basename of the template, e.g., <TemplateReference 'view.html'>. You could parse this with a filter, e.g., {{ self | quoted }}

@app.template_filter('quoted')
def quoted(s):
    l = re.findall('\'([^\']*)\'', str(s))
    if l:
        return l[0]
    return None

If you need the full path, e.g., '/full/path/to/view.html' you may want to subclass Template.
