Replace your AuthorAdmin class with the code below. The field names to be displayed in the list are declared in a tuple in the required order, as shown these are the same names as specified in your original model. Now navigate to the author list in your website. The fields above should now be displayed, like so:. For our Book model we'll additionally display the author and genre.
Replace the BookAdmin class with the version below. Note: Getting the genre may not be a good idea here, because of the "cost" of the database operation. We're showing you how because calling functions in your models can be very useful for other reasons — for example to add a Delete link next to every item in the list.
Add the following code into your Book model models. After saving the model and updated admin, open your website and go to the Books list page; you should see a book list like the one below:. The Genre model and the Language model, if you defined one both have a single field, so there is no point creating an additional model for them to display additional fields. Note: It is worth updating the BookInstance model list to show at least the status and the expected return date.
We've added that as a challenge at the end of this article! Once you've got a lot of items in a list, it can be useful to be able to filter which items are displayed. Replace your current BookInstanceAdmin class with the code fragment below. The list view will now include a filter box to the right. Note how you can choose dates and status to filter the values:. By default, the detail views lay out all fields vertically, in their order of declaration in the model.
You can change the order of declaration, which fields are displayed or excluded , whether sections are used to organize the information, whether fields are displayed horizontally or vertically, and even what edit widgets are used in the admin forms.
Note: The LocalLibrary models are relatively simple so there isn't a huge need for us to change the layout; we'll make some changes anyway however, just to show you how. Update your AuthorAdmin class to add the fields line, as shown below:. The fields attribute lists just those fields that are to be displayed on the form, in order.
Fields are displayed vertically by default, but will display horizontally if you further group them in a tuple as shown in the "date" fields above.
Note: You can also use the exclude attribute to declare a list of attributes to be excluded from the form all other attributes in the model will be displayed.
You can add "sections" to group related model information within the detail form, using the fieldsets attribute. In the BookInstance model we have information related to what the book is i. We can add these to our BookInstanceAdmin class as shown below, using the fieldsets property. Each section has its own title or None , if you don't want a title and an associated tuple of fields in a dictionary — the format is complicated to describe, but fairly easy to understand if you look at the code fragment immediately above.
Sometimes it can make sense to be able to add associated records at the same time. For example, it may make sense to have both the book information and information about the specific copies you've got on the same detail page. You can do this by declaring inlines , of type TabularInline horizontal layout or StackedInline vertical layout, just like the default model layout.
You can add the BookInstance information inline to our Book detail by specifiying inlines in your BookAdmin :. Now navigate to a view for a Book in your website — at the bottom you should now see the book instances relating to this book immediately below the book's genre fields :.
In this case all we've done is declare our tabular inline class, which just adds all fields from the inlined model. You can specify all sorts of additional information for the layout, including the fields to display, their order, whether they are read only or not, etc. Note: There are some painful limits in this functionality! In the screenshot above we have three existing book instances, followed by three placeholders for new book instances which look very similar!
It would be better to have NO spare book instances by default and just add them with the Add another Book instance link, or to be able to just list the BookInstance s as non-readable links from here. The first option can be done by setting the extra attribute to 0 in BooksInstanceInline model, try it by yourself.
You've now learned how to set up the administration site in both its simplest and improved form, how to create a superuser, and how to navigate the admin site and view, delete, and update records.
Along the way you've created a bunch of Books, BookInstances, Genres, and Authors that we'll be able to list and display once we create our own view and templates.
