If you are looking for a way to update for change many objects at once via admin panel then the best way is to use Django's admin action. By setting a custom action you can change the object list in the admin by selecting the objects you want to change and go to the bottom of the page where you can see a drop down. Click on the drop down and it will show a list of admin action including the custom action that you have created. By default you can see 'Delete Selected User' action.
Creating Sample Model
Lets create a sample table in models.py to.
from django.db import models
class ProductsUpdated(models.model):
'''
Model for storing the product basic updation details.
'''
name = models.CharField(max_length=250)
price = models.FloatField(default=0.0)
updated = models.BooleanField(default=False)
def __unicode__(self):
return self.name
Writing Custom Action
In admin.py
from django.contrib import admin
def updated(modeladmin, request, queryset):
'''
Custom action method
'''
queryset.update(updated=True) # Updating the 'úpdated' field
updated.short_description="Items Updated" # Description thats shown in the bottom drop down
Now call the action method in the admin of the table ProductsUpdated.
The whole code would look like this:
from django.contrib import admin
from myapp.models import ProductsUpdated
def updated(modeladmin, request, queryset):
queryset.update(updated=True)
updated.short_description = "Items Updated"
def ProductsUpdatedAdmin(admin.ModelAdmin):
list_display = [ 'title', 'úpdated']
action = [updated]
admin.site.register(ProductsUpdated, ProductsUpdatedAdmin)
