Django TemplateTag evaluating to a boolean

阅读更多关于 Django TemplateTag evaluating to a boolean

问题 Is it possible to create a Django template tag which evaluates to a boolean? Eg, can I do: {% if my_custom_tag %} .. {% else %} .. {% endif %} At the moment I've written it as an as tag, which works fine like this: {% my_custom_tag as var_storing_result %} But I was just curious if I could do it the other way as I think it'd be nicer if I didn't have to assign the result to a variable first.

Django – remove trailing zeroes for a Decimal in a template

阅读更多关于 Django – remove trailing zeroes for a Decimal in a template

There are answers suggesting to do this using the floatformat filter: {{ balance.bitcoins|floatformat:3 }} However, floatformat performs rounding (either down or up), which is unwanted in my case, as I only need to remove trailing zeros without any rounding at all. 回答1: The solution is to use the normalize() method: {{ balance.bitcoins

I never thought it would be so hard to use multi-dimensional arrays or dictionaries as you pythoners call them. So I can create multi-dimensional arrays using this, but i can't loop it in a django template. this doesnt work but i imagine i cant loop through it if i could get it to work. {% for key,val in dictionary.items %} only works for actual dictionaries
