我如何写一个数字循环在Django模板?我的意思是

for i = 1 to n

为了防止其他人遇到这个问题,我创建了一个模板标签,可以创建一个范围(…):http://www.djangosnippets.org/snippets/1926/

Accepts the same arguments as the 'range' builtin and creates a list containing
the result of 'range'.

Syntax:
    {% mkrange [start,] stop[, step] as context_name %}

For example:
    {% mkrange 5 10 2 as some_range %}
    {% for i in some_range %}
      {{ i }}: Something I want to repeat\n
    {% endfor %}

Produces:
    5: Something I want to repeat 
    7: Something I want to repeat 
    9: Something I want to repeat

你可以使用: {% with " |center: I as range %}

不幸的是,Django模板语言不支持这一点。有一些建议,但它们看起来有点复杂。我只要在上下文中放一个变量:

...
render_to_response('foo.html', {..., 'range': range(10), ...}, ...)
...

在模板中:

{% for i in range %}
     ...
{% endfor %}

你可以通过:

{'n':范围(n)}

使用模板:

{% for I in n %} ... {% endfor %}

的绑定

{'n' : range(n) }

到模板,然后做

{% for i in n %}
...
{% endfor %}

注意,您将得到基于0的行为(0,1,…)n - 1)。
