我如何写一个数字循环在Django模板?我的意思是

for i = 1 to n

当前回答

你应该在模板中使用“slice”,一个这样的例子:

在views.py

contexts = {
    'ALL_STORES': Store.objects.all(),
}

return render_to_response('store_list.html', contexts, RequestContext(request, processors=[custom_processor]))

在store_list.html:

<ul>
{% for store in ALL_STORES|slice:":10" %}
    <li class="store_item">{{ store.name }}</li>
{% endfor %}
</ul>

其他回答

{% for i in range(10) %}
   {{ i }}

{% endfor %}

我使用了一种简单的技术,可以很好地处理没有特殊标记和附加上下文的小情况。有时这很有用

{% for i in '0123456789'|make_list %}
    {{ forloop.counter }}
{% endfor %}
{% for _ in ''|center:13 %}
    {{ forloop.counter }}
{% endfor %}

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

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 %}
