Flexible handling of quantity changes: In AnQiCMSpluralizeDetailed explanation of the filter

In the dynamic content display on the website, such as showing product inventory, comment count, or the number of search results, we often need to adjust the descriptive text for singular and plural forms based on specific numbers.For example, when there is '1 Item', we expect to display '1 Item', and when there are '0' or '2' items, we need to display '0 Items' or '2 Items'.pluralizeThe filter is exactly born to solve this pain point.

This filter can intelligently add the appropriate plural form to the word endings based on the values it receives, making your content output more grammatically correct and enhancing the reading experience for users.

Basic Usage: The default “s” rule

pluralizeThe most basic usage of the filter is to directly act on a numeric variable, it follows the most common plural rules in English: when the quantity is 0 or greater than 1, it adds a's'When the quantity is exactly 1, the word is kept unchanged without adding any suffix.

For example, suppose we have a variablecountWe want to display the singular or plural form of 'customer' based on its value:

customer{{ count|pluralize }}

IfcountThe value of0The output will be:customers. IfcountThe value of1The output will be:customer. IfcountThe value of2The output will be:customers.

In this way, without additionalifcondition judgment,pluralizeThe filter can automatically handle the pluralization conversion in most cases.

Custom plural endings: for irregular changes

In English, not all words follow the simple rule of adding an 's' to form the plural, some have rather special plural forms, such as 'cherry' becomes 'cherries', and 'walrus' becomes 'walruses'. For these irregular changes, pluralizeThe filter provides a flexible custom suffix feature.

You can check if the content is empty bypluralizeAfter the filter, provide one or two comma-separated strings to customize the suffix.

1. Provide a custom suffix (for 0 or more, 1 remains unchanged):

If you provide only a custom suffix, this suffix will be applied to the end of the word when the quantity is 0 or greater than 1, and the word remains unchanged when the quantity is 1. This applies to those plural forms that are simply addedesOr words ending with specific suffixes.

walrus{{ count|pluralize:"es" }}

IfcountThe value of0The output will be:walruses. IfcountThe value of1The output will be:walrus. IfcountThe value of2The output will be:walruses.

2. Provide two custom suffixes (one for 1, and 0 or more):

For those words with more complex singular and plural forms, such as words ending with 'y' that become 'ies' when pluralized, you can provide two custom suffixes. In this case, the first suffix will be used for quantities of1[en]the case, while the second suffix is used for quantities of0or greater1[en]the case. It should be noted that the suffix you provide is used to directly replace the corresponding part of the word.

cherr{{ count|pluralize:"y,ies" }}

IfcountThe value of0The output will be:cherries. IfcountThe value of1The output will be:cherry. IfcountThe value of2The output will be:cherries.
