Display form errors with django and ajax

由 别等时光非礼了梦想. 提交于 2021-02-06 09:08:34
问题 I have a contact form through which users would be able to contact me. I am using django with ajax, and it works fine if there's no error. I would like to show the errors if there's any like it displays above the input fields and not just the errors, but both the input and the errors. It does however differentiate between the success and error result, as the ajax request was successful. But I need to display the actual form errors. How do I that? Your help will be very much appreciated. Thank

Knockout components (not) binding on new content

由 若如初见. 提交于 2021-02-06 08:42:18
