How to limits the number of characters/words in Django templates

Django uses templates filter to limit the number of characters

• If the desired stage is a string, you can use a slice filter, which treats the string as a list of characters. 
• If it is a set of words, the rough equivalent words are truncatewords.

truncatewords added an ellipsis … at the end of the truncated result.

Example of slice usage¶

{{ variable|slice:":255" }}

Examples of using truncatewords¶

{{ variable|truncatechars:255 }}
