In the template world of AnQi CMS, dynamic display of content is a key factor in enhancing user experience.How can we make the related words flexibly show the correct singular or plural form according to the number of data on our website, rather than showing them uniformly?pluralizeFilter, it can help us easily solve this problem, making your website content more natural and more in line with language habits.

pluralizeFilter: Let words change smartly according to the quantity.

Imagine that your website displays the number of articles, user comments, or product stock.When the quantity is '1', we expect to see '1 article' or '1 comment'; when the quantity is '0' or '2' or more, it should be '0 articles', '2 articles', or 'multiple comments'.If you always manually write complex conditional judgments to switch these texts, it is not only tedious but also prone to errors.pluralizeThe filter is designed to solve such problems, it automatically determines and adjusts the singular and plural forms of words based on the numbers you provide.

The template engine syntax of Anqi CMS is similar to Django, which means you can use the familiar{{ 变量|过滤器:参数 }}format to applypluralizeFilter. This filter accepts a number as input and can optionally accept additional parameters to handle irregular singular/plural changes.

Core Usage Explanation

pluralizeThe basic function of the filter is to adjust the ending of words based on numbers 0, 1, 2 or more. It has several common usage methods:

情景一：默认处理 (添加 's')

This is the most common usage, suitable for most words that only need to add an 's' after the plural form, such as 'book' becomes 'books', 'item' becomes 'items'. When the number is 1,pluralizeThe filter will not add any characters; while when the number is 0 or greater than 1, it will default to adding “s” at the end of the word.

{% set count = 0 %}您有 {{ count }} friend{{ count|pluralize }}.
{% set count = 1 %}您有 {{ count }} friend{{ count|pluralize }}.
{% set count = 2 %}您有 {{ count }} friend{{ count|pluralize }}.

Output will be: You have 0 friends. You have 1 friend. You have 2 friends.

Scenario two: Custom plural form (single parameter)

Some words have plural forms that are not just a simple addition of 's', but may require 'es' (for example, 'box' becomes 'boxes'). In this case, you can bepluralizeThe filter provides a parameter, which is the suffix that needs to be added when it is plural.

{% set count = 0 %}显示 {{ count }} walrus{{ count|pluralize:"es" }}.
{% set count = 1 %}显示 {{ count }} walrus{{ count|pluralize:"es" }}.
{% set count = 2 %}显示 {{ count }} walrus{{ count|pluralize:"es" }}.

输出结果会是： 显示 0 walruses. 显示 1 walrus. 显示 2 walruses.

Scenario three: Custom singular and plural forms (two parameters)

When the singular and plural forms of a word differ significantly, or the ending of the singular form needs to change (such as "cherry" becomes "cherriesThe first parameter indicates the character (or empty) to be replaced in the singular form, and the second parameter indicates the character to be added in the plural form.

{% set count = 0 %}有 {{ count }} cherr{{ count|pluralize:"y,ies" }}.
{% set count = 1 %}有 {{ count }} cherr{{ count|pluralize:"y,ies" }}.
{% set count = 2 %}有 {{ count }} cherr{{ count|pluralize:"y,ies" }}.

The output will be: There are 0 cherries. There is 1 cherry. There are 2 cherries.
