Django Generic Views
Generic views in Django are built-in class-based views. Generic views are developed to eliminate repetitive coding by providing frequently used logic in class format. Using generic views, you can build web applications with simple code.
Different types of generic views are used depending on the objectives. In Chapter 2, we explained TemplateView, which is categorized under Base views. Base views also include View, which is the ancestor of all other class-based views, and RedirectView, which is used for URL redirections.
In a simple CRUD application, there are five frequently used generic views.
- ListView
- DetailView
- CreateView
- UpdateView
- DeleteView
They are categorized into two groups depending on their purposes – generic display views and generic editing views.
Generic display views
Generic display views are designed to display data. There are two views under this category – ListView and DetailView.
ListView
ListView is used to provide logic to display a list of objects. For example, ListView retrieves a list of blog articles from a database in the blog application.
DetailView
DetailView is used to provide logic to display a particular object. For example, the blog application retrieves a particular blog article from a database.
Generic editing views
Generic editing views are designed to provide a foundation for editing content. There are four views under this category – FormView, CreateView, UpdateView, and DeleteView. In this Chapter, we'll cover the following three views.
CreateView
CreateView is used to provide logic to display an input form to create an object. When inputs are submitted, CreateView handles the inputs and registers the data in a database.
UpdateView
UpdateView is used to provide logic to display an input form to update an object. When inputs are submitted, UpdateView handles the modification of the registered data in a database.
DeleteView
DeleteView is used to provide logic to display a page for the data delete action and handle the data delete process.
