Template Variables with Fortune Teller

Path: /fortunecookie Change your fortune cookie handler so that http://localhost:8080/fortunecookie?/num=2 displays the 2nd fortune in your list. However be sure that the default, http://localhost:8080, still gives a random fortune.

Path: /8ball Create a dictionary with three keys: “positive”, “neutral” and “negative”. Their corresponding values are a list of 8ball responses. http://localhost:8080/8ball?/type=pos will give the 2nd response from your positive list of 8 ball responses.

You can make your own lists of responses, or use the default values, which contain 10 positive, 5 neutral and 5 negative answers.

Reminders

Passings variables to a template:

Pass a dictionary of key:values as an argument to template.render():

template.render({"first_name": "Jay-Z"})

Often times you’ll want to do this as two seperate steps in order to make your code easier to read

• Make a dictionary of values

  my_variables = {"first_name": "Beyonce",
                  "last_name": "Knowles",
                  "home_town": "Houston",
                  "profession": "Hero"}
  

• Pass that dictionary as an argument to template.render():

  template.render(my_variables)

Getting variables from a URL

A url can pass variables through its query string which starts after the question mark character. An ampersand (&) indicates a new variable:

http://amazon.com/home?item_name="bannana%phone"&seller_id=19

To access those variables, use the self.request.get() method:

template_vars = {"item": self.request.get('item_name')}

You can also set a default value by adding an optional second argument, default_value:

self.request.get('feeling', default_value='happy')}
