whilewordwrapFilter, according to the official document of AnQiCMS, is atemplate-level filter。It mainly functions to automatically wrap long text to the specified length during AnQiCMS template rendering. For example, when you use it in the template,{{ obj|wordwrap:number }}Such syntax, when AnQiCMS's template engine processes,objthe text represented by this will be output to the HTML page before, according tonumberthe length specified by the parameter, a newline character is inserted.

This meanswordwrapfilter andDoes not directly support preprocessing text on the AnQiCMS backend.It will not automatically format text with line breaks when content is saved to the database, nor will it alter the original structure of the text when it is loaded from the database without template rendering.Display layer of the front-end page.

In other words, if your text is 'Anqi CMS is a system developed based on the Go language', in the applicationwordwrapThe filter will only find potential line breaks between "Go language" and "development
