Question

PHP has $_SERVER['DOCUMENT_ROOT'] as a reference to the base url of a website: e.g. http://localhost:8080/. I need to do the same in jinja2. I am using python 2.7 on app engine.

How do I get the base url of website in jinja2?

Answer 1

In webapp2, you can get the host part of a request and pass it as argument in a jinja template as follows:

class YourHandler(webapp2.RequestHandler):
  def get(self):
    params = {'url':self.request.host}
    template = jinja_environment.get_template('your_template.html')
    self.response.write(template.render(params))
