{{ 数值 | pluralize }}

For example, we want to display the number of customers on the website. Suppose you have a variablecustomer_countIt stores the number of customers, you can use it like thispluralizeFilter:

<p>您有 {{ customer_count }} customer{{ customer_count|pluralize }}.</p>

Whencustomer_countThe value is1The output will be:您有 1 customer.

whencustomer_countThe value is0/2or any other non1When the number is, the output will be:您有 0 customers. 您有 2 customers.

1. Provide two suffixes:"单数后缀,复数后缀"This method is suitable for situations where both singular forms require specific suffixes and the plural forms are completely different. For examplecherryIts singular ischerr+yIts plural ischerr+ies.

   <p>树上有 {{ cherry_count }} cherr{{ cherry_count|pluralize:"y,ies" }}.</p>
   

   Whencherry_countWith1When it comes to output1 cherry.Whencherry_countWith0or2When it comes to output0 cherries.or2 cherries.

2. Only a suffix is provided:"复数后缀"This method is suitable for the singular form where the word stem is the same, and only a specific suffix is added for the plural. For examplewalrus, and its plural iswalrus+es.

   <p>我在海里看到了 {{ walrus_count }} walrus{{ walrus_count|pluralize:"es" }}.</p>
   

   Whenwalrus_countWith1When it comes to output1 walrus.Whenwalrus_countWith0or2When it comes to output0 walruses.or2 walruses.
