7. Django 1.8 Server Build - CentOS 7 hosted on VPS - Model 2

In previous chapter (6. Django 1.8 Server Build - CentOS 7 hosted on VPS - Model), we setup Django model.

In this chapter, we'll populate the tables Cars and Makes.

Let's start filling the data for Cars:

Here is the table we built so far.

Cars:

And Makes:

Note that the name is the returned value from __unicode__(self):

class Car(models.Model):
        name = models.CharField(max_length=200)
        slug = models.SlugField(unique=True)
        make = models.ForeignKey('Make')
        locality = models.CharField(max_length=1, choices=CAR_CHOICES)
        description = models.TextField(blank=True)

        def __unicode__(self):
                return self.name


class Make(models.Model):
        name = models.CharField(max_length=200)
        slug = models.SlugField(unique=True)
        description = models.TextField(blank=True)

        def __unicode__(self):
                return self.name

We want to the Slug field can be filled automatically when we type the name.

Let's go to the car app, and edit admin.py:

from django.contrib import admin
from car.models import Car, Make

class CarAdmin(admin.ModelAdmin):
    prepopulated_fields = {'slug':('name',)}

admin.site.register(Car, CarAdmin)
admin.site.register(Make)

Restart the web server:

$ sudo apachectl restart

As we can see the picture below, while we typing the name of a car, the slug is filled automatically:

We can do the same to Make as well:

from django.contrib import admin
from car.models import Car, Make

class CarAdmin(admin.ModelAdmin):
    prepopulated_fields = {'slug':('name',)}
    list_display = ('name','make','locality')

class MakeAdmin(admin.ModelAdmin):
    prepopulated_fields = {'slug':('name',)}

admin.site.register(Car, CarAdmin)
admin.site.register(Make, MakeAdmin)

Note that we also add the list_display.

Restart the server:

$ sudo apachectl restart

Refresh the Admin page:

Aw we can see from the picture, thanks to the list_display, we now have additional two columns.

If we click "Make", it will have sorted display:

Now we want to add "search":

from django.contrib import admin
from car.models import Car, Make

class CarAdmin(admin.ModelAdmin):
    prepopulated_fields = {'slug':('name',)}
    list_display = ('name','make','locality')
    search_field = ['name']

class MakeAdmin(admin.ModelAdmin):
    prepopulated_fields = {'slug':('name',)}

admin.site.register(Car, CarAdmin)
admin.site.register(Make, MakeAdmin)

Restart the server again:

$ sudo apachectl restart

Refresh the Admin page:
