I am writing a template for my first django website.

I am passing a list of dictionaries to the template in a variable. I also need to pass a few other lists which hold boolean flags. (Note: all lists have the same length)

The template looks something like this:

<html>
    <head><title>First page</title></head><body>
        {% for item in data_tables %}
        <table>
        <tbody>
                  <tr><td colspan="15">
                  {% if level_one_flags[forloop.counter-1] %}
                  <tr><td>Premier League
                  {% endif %}
                  <tr><td>Junior league
                  <tr><td>Member count
                  {% if level_two_flags[forloop.counter-1] %}
                  <tr><td>Ashtano League
                  {% endif %}
             </tbody>
        </table>
        {% endfor %}
  </body>
</html>

I am getting the following error:

Template error

In template /mytemplate.html, error at
line 7 Could not parse the remainder:
‘[forloop.counter-1]’ from
‘level_one_flags[forloop.counter-1]’

I am, not suprised I am getting this error, since I was just trying to see if would work. So far, from the documentation, I have not found out how to obtain the items in a list by index (i.e. other than by enumeration).

Does anyone know how I may access a list by index in a template?

    You use the dot-operator to index the array, or, really, to do anything.

    Technically, when the template system
    encounters a dot, it tries the
    following lookups, in this order:

    * Dictionary lookup
* Attribute lookup
* Method call
* List-index lookup

    I don’t believe you can do math on the index. You’ll have to pass in your array constructed in some other way so that you don’t have to do this subtraction.
