Customized administration Web site.
63.3.8 Customize the Admin Site
The application already has the basic functions of a database, such as add, change, and delete. But it is
not good enough for application. The following steps will make the database much more powerful:
1. Add the Python code below into the models.py file. This will use the document names as the
links to visit the related documents.
def __ unicode __ (self):
return self.document _ name
2. Edit the admin.py file using the code below. This will list all the document information row by
row. In the table, all the document information can be ordered by either document name, author
name, or submission date.
from paper _ system.documents.models import Document
from django.contrib import admin
class DocumentAdmin(admin.ModelAdmin):
list _ display = ('document _ name','document _ auth','sub _ date')
admin.site.register(Document, DocumentAdmin)
3. Add code below to admin.py file. This will create sidebar used to filter the listed document
information by specified date.
list _ filter = ['sub _ date']
4. Add code below to admin.py file. This will add a search box at the top of the document list,
which can be used to search document information by author name.
search _ fields = ['document _ auth']
5. Add code below to admin.py file. This will add hierarchical navigation by submission date.
date _ hierarchy = 'sub _ date'
With all the above customization, the new administration Web site is as shown in Figure 63.11.
63.4 Conclusion
The above example built a framework for a database-driven Web site server. It includes interface design
and basic SQL operations, such as create, search, add, and delete. As one may notice, the entire project
is done in a considerably limited time and with very few codes.
By conclusion, the major features of Django can be described as follows [B08]:
• Object-relational mapper: By defining the data models in Python, Django can offer an efficient
and dynamic database access APIs for free.
• Automatic admin interface: Django does all the work of creating interfaces automatically, avoiding
tedious and duplicated coding.
