I want to see if the number of elements in an array in my Django template is greater than 1. Can i use the following syntax for doing that ?
{% if {{myarr|length}} > 1 %} <!-- printing some html here --> {% endif %} Thank You

{{ foo }} - this is a placeholder in the template, for the variable foo that is passed to the template from a view. {% %} - when text is surrounded by these delimiters, it means that there is some special function or code running, and the result of that will be placed here.
If the QuerySet only exists to count the amount of rows, use count(). If the QuerySet is used elsewhere, i.e. in a loop, use len() or |length. Using count() here would issue another SELECT-query to count the rows, while len() simply counts the amount of cached results in the QuerySet.
The include tag allows you include a template inside the current template. This is useful when you have a block of content that are the same for many pages.
{% include %} Processes a partial template. Any variables in the parent template will be available in the partial template. Variables set from the partial template using the set or assign tags will be available in the parent template.
As of Django 1.2; if supports boolean operations and filters, so you can write this as:
{% if myarr|length > 1 %} <!-- printing some html here --> {% endif %} See the Django Project documentation for if with filters.

no. but you can use django-annoying, and {% if myarr|length > 1 %} will work fine.
