My app (FreeBSD, Django 1.9.4, totally developped using the Admin Site) uses,
among othe things, the model "Order" and "OrderDetail" as its inline (see
below a simplified version).
The "OrderDetail" model overrides the default save by means of a somewhat
elaborate save function with a long workflow.
Now it happens that if a user working on the inlines of an Order rapidly and
*** frantically **** (or I'd better say "Hysterically") clicks many times on
the "Save and continue editing" button the related instance is recorded more
than once.
Therefore I would like to disable the "Save", "Save and continue editing", and
"add another" buttons while saving inlines at the very beginning of the save
function and re-enable them at the very end of it.
How can I do this?
=================
models.py
.................................
class Items(models.Model):
code = models.CharField(primary_key=True,max_length=15,db_column='code')
description = models.CharField(max_length=255, db_column='Description',
db_index=True)
category = models.IntegerField(choices=categoria,
db_column='Category',default=2)
total_quantity_in_store=models.IntegerField(db_column='total_quantity_in_store',
default=0)
def __unicode__(self):
return self.description
class Order(models.Model):
id_order = models.IntegerField(primary_key=True,db_column='id_order')
patient = models.ForeignKey(Patients, db_column='patient')
def __unicode__(self):
return u"Ord.%s per %s" % (self.id_order, self.paziente)
class OrderDetail(models.Model):
id_order = models.ForeignKey(Order,db_column='id_order')
item_code = models.ForeignKey(Items,verbose_name='Items')
quantity = models.IntegerField(db_column='quantity',blank=True,default=0)
def save(self):
# HERE I WOULD LIKE TO DISABLE/MAKE DISAPPEAR THE "Save", "Save and
continue editing", and "add another" BUTTONS
.......
super(OrderDetail,self).save()
.......
# HERE I WOULD LIKE TO ENABLE/MAKE APPEAR AGAIN THE "Save", "Save and
continue editing", and "add another" BUTTONS
return
==================
admin.py
......................
class OrderDetailInline(admin.TabularInline):
model=OrderDetail
raw_id_fields = ['item_code',]
fields=('item_code', 'quantity',)
class OrderOption(admin.ModelAdmin):
readonly_fields = ['order_id', 'patient']
list_display = ( 'patient','order_id')
fields=( 'order_id', 'patient')
inlines=[OrderDetailInline,]
admin.site.register(Order,OrderOption)
