Django's contributed <a href="http://docs.djangoproject.com/en/dev/ref/contrib/humanize/#ref-contrib-humanize" rel="noreferrer">humanize</a> application does this:

<pre><code>{% load humanize %}
{{ my_num|intcomma }}
</code></pre>

Be sure to add <code>'django.contrib.humanize'</code> to your <code>INSTALLED_APPS</code> list in the <code>settings.py</code> file.

Regarding Ned Batchelder's solution, here it is with 2 decimal points and a dollar sign. This goes somewhere like <code>my_app/templatetags/my_filters.py</code>

<pre><code>from django import template
from django.contrib.humanize.templatetags.humanize import intcomma

register = template.Library()

def currency(dollars):
 dollars = round(float(dollars), 2)
 return "$%s%s" % (intcomma(int(dollars)), ("%0.2f" % dollars)[-3:])

register.filter('currency', currency)
</code></pre>

Then you can

<pre><code>{% load my_filters %}
{{my_dollars | currency}}
</code></pre>

If you don't want to get involved with locales here is a function that formats numbers:

<pre><code>def int_format(value, decimal_points=3, seperator=u'.'):
 value = str(value)
 if len(value) &lt;= decimal_points:
 return value
 # say here we have value = '12345' and the default params above
 parts = []
 while value:
 parts.append(value[-decimal_points:])
 value = value[:-decimal_points]
 # now we should have parts = ['345', '12']
 parts.reverse()
 # and the return value should be u'12.345'
 return seperator.join(parts)
</code></pre>

Creating a <a href="http://docs.djangoproject.com/en/dev/howto/custom-template-tags/#writing-custom-template-filters" rel="noreferrer">custom template filter</a> from this function is trivial.

blocks|key|1458658|text|我找不到Django的方式，但我在我的模型中找到了一种python的方式：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1458659|def+format_price(self):

Well I couldn't find a Django way, but I did find a python way from inside my model:

<pre><code>def format_price(self):
 import locale
 locale.setlocale(locale.LC_ALL, '')
 return locale.format('%d', self.price, True)

You can also use this in your Django code (outside templates) by calling <code>localize(number)</code>.

blocks|key|1458825|text|请注意，更改区域设置是在整个进程范围内进行的，并且不是线程安全的(低，可能会产生副作用，也可能会影响在同一进程中执行的其他代码)。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1458826|我的建议是:查看Babel包。与Django模板集成的一些方法是可用的。|offset|length|1458827|entityMap|0|LINK|mutability|MUTABLE|url|http://babel.edgewall.org/^0|0|8|5|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@]|9|@$D|P|E|Q|1|R]]|A|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|A|$]]]|G|$H|$5|I|J|K|A|$L|M]]]]

Be aware that changing locale is process-wide and not thread safe (iow., can have side effects or can affect other code executed within the same process).

My proposition: check out the <a href="http://babel.edgewall.org/" rel="nofollow noreferrer">Babel</a> package. Some means of integrating with Django templates are available.

I'm trying to format numbers. Examples:

<pre><code>1 =&gt; 1
12 =&gt; 12
123 =&gt; 123
1234 =&gt; 1,234
12345 =&gt; 12,345
</code></pre>

It strikes as a fairly common thing to do but I can't figure out which filter I'm supposed to use.

Edit: If you've a generic Python way to do this, I'm happy adding a formatted field in my model.

Format numbers in django templates

Django

Python

我在试着格式化数字。示例：1     => 112    => 12123   => 1231234  => 1,23412345 => 12,345这是一件很常见的事情，但是我不知道我应该使用哪个过滤器。编辑:如果您有一种通用的Python方法可以做到这一点，我很乐意在我的模型中添加一个格式化的字段。
