In this course, you will learn the basics of the Django Admin interface, a great tool to build a powerful admin interface quickly for your Django project. 

First, you will learn how to automatically generate the admin interface for your Django models, how to populate fake data, and then search or filter data with some advice to improve performance. 

Next, you will see how to extend the functionalities of the admin interface such as adding custom fields, add intermediate pages, or creating custom actions like exporting data in CSV format.

After that, you will also explore basic and advanced UI customization such as adding charts or modifying the index page.Finally, you will have a look at the Django admin rights permission management.

The Django Admin for Web Developers

# Retrieving foreign key

If your model has a foreign key (like the `Author` for our `Question` model or `Question` for our `Choice` model), set `list_select_related` to instruct Django to use `select_related()` in retrieving the list of objects on the admin change list page. This can save you a bunch of database queries. You can do the following for your `QuestionAdmin`.

```python
list_select_related = ('refAuthor',)
```
And for your `ChoiceAdmin` you can do something similar:

```python
list_select_related = ('question','question__refAuthor',)
```
# Autocomplete fields
If you have a foreign key in your model, which could have thousands of results, you can set an `autocomplete_fields` whereby in the creation/edition form of your model, you will have a search box (to find authors). It is more efficient than selecting an `Author` with a select-box interface (default appearance in Django admin for foreign keys). But for it to work properly, you will need to define a `search_fields` in your foreign key model admin to indicate which fields you want to search.

TAKE a look at your `Question`/`Author` models.

In your `AuthorAdmin` model, you will add a `search_field` on the `name`:

```python
class AuthorAdmin(admin.ModelAdmin):
	empty_value_display = 'Unknown'
	fieldsets = [
		("Author information", {'fields': ['name']}),
	]
	list_display = ('name','createdDate','updatedDate',)
	search_fields = ('name',)
```
And then on the `QuestionAdmin`, you will add an `autocomplete_fields` on the `refAuthor` foreign key

```python
class QuestionAdmin(admin.ModelAdmin):
....
autocomplete_fields = ['refAuthor']
....
```
The interface will look like this:
