In the template development of AnQiCMS,wordcountFilter is undoubtedly a very practical tool, it can help us quickly count the number of words in articles, product descriptions, and other content.However, simply obtaining a number is often not enough, we may wish to present this number in a more readable or professional format to visitors.stringformatThe filter comes into play, it canwordcountformat the integer results precisely, making the display of numbers more in line with the overall design and user experience of the website.

Deep understandingwordcountFilter

{{ archive.Content|wordcount }}

This simple expression will directly output a pure number, such as520，represents that the article has 520 words. Although the result is accurate, such a bare number may not be very intuitive or lack context in actual page display.

MasterstringformatThe formatting magic of the filter

Next,stringformatThe filter will bring us more possibilities in display.This filter is very powerful, it allows you to output different types of data (including numbers, floating-point numbers, boolean values, etc.) in a new string according to the format rules you specify.fmt.Sprintf()Function, to precisely control the output style through formatting placeholders.

For the formatting of integer results,stringformatThe most commonly used placeholders are%dIt represents outputting an integer in decimal form. In addition,%vIt is a general placeholder that can intelligently format according to the data type.

{{ 123|stringformat:"文章编号：%d" }}

This will output:文章编号：123You can see,%dReplaced with the actual number.

Combined use: letwordcountThe result shines with brilliance

Now, we willwordcountandstringformatThese two filters combined to achieve a richer and more user-friendly digital display effect. The core idea is to first utilizewordcountObtained the original integer result, then use this result as input, through the pipe symbol|Pass tostringformatPerform secondary processing.

The following is a typical application example, assuming you want to display the actual word count of the article in the sidebar of the article detail page, along with the unit 'words':

<p>文章总字数：{{ archive.Content|wordcount|stringformat:"%d字" }}</p>

Ifarchive.ContentThe word count is520So the page will display as文章总字数：520字So visitors can immediately understand the meaning of this number.

Further, you can also add additional text descriptions to numbers based on design requirements, or use more complex fill formats. For example, if you want to emphasize the word count of a specific article and display it in a more prominent way:

<p>这篇文章共计：<b>{{ archive.Content|wordcount|stringformat:"%d" }}</b> 个词。</p>

In this example,<b>Labels make numbers bold, andstringformatis responsible for embedding numbers into the descriptive text 'word', making the output both clear and stylish.

<p>文章字数编号：{{ archive.Content|wordcount|stringformat:"%03d字" }}</p>

Here,%03dRepresents formatting an integer as at least three digits, padding with zeros if it's less than three digits. This unified format makes the page look more tidy and professional.
