How to Override get_absolute_url in Django for different Fields?
I want to make the method get_absolute_url to be dynamic with different class based views. So if in a template where it displays a list of all the articles in the database I call the function for the attribute as {{ instance.get_absolute_url }}, that link will take me to blog/article/title. But then I want to have a page that displays all the authors in the database and when I click in an author, the next page would display all the articles of that author, so the url would be blog/author/authorname. The problem is that I overrode the method in the Article class as follows: reverse(blog:article-detail, kwargs={'title': self.title}) What do I have to do to implement a conditional that checks whether I am looking for the author or the title. I've tried overriding the method inside the AuthorArticleListView class that I created to render the template where the author's articles will be displayed but when calling the get_absolute_url method in the template, the link would just not work and stays in the same page, does not even give me an error but when called for the articles to go into the DetailView of each article from the ListView, it works just … -

Django form validation based on custom function that calls api to validate form input value
I've been trying to look around for resources on how to do this, but no luck so far. Any direction would be appreciated! I'm attempting to run a custom function on a Django form as validation. So, how it would work is: User submits form Within the validation, there is a function that calls an external API with the input value If the API returns a valid response, the form submission completes successfully If the API returns an error, the form validation is failed and a notification is returned to frontend with error. Any direction on how this could be accomplished would be appreciated! -
