Replacing a character in Django template

Replacing a character in Django template

To replace a character in a Django template, you can use the |replace filter, which allows you to replace occurrences of one substring with another substring within a variable's value. Here's how you can use it in your Django template:

Assuming you have a variable my_string in your template, and you want to replace all occurrences of a specific character, such as 'A', with another character, such as 'B', you can do the following:

{% with my_string|replace:"A":"B" as modified_string %} {{ modified_string }} {% endwith %}

In this example:

  • We use the with template tag to create a new variable modified_string that stores the result of applying the replace filter to my_string.

  • Inside the replace filter, we specify the character 'A' that we want to replace, followed by the character 'B' that we want to replace it with.

  • Finally, we display the modified_string variable, which contains the original string with the desired character replacements.

You can adjust the characters 'A' and 'B' to your specific replacement needs. This approach allows you to replace characters within a variable's value in a Django template.
