Hello all,
I just run a command to Add foreign key to the existing table. and the command was like this:
ALTER TABLE acfs_subscriptionmaster ADD CONSTRAINT FK_Formats FOREIGN KEY (id) REFERENCES acfs_formats (id) MATCH FULL;
It has got executed. but giving error on the interface
column acfs_subscriptionmaster.FK_Formats_id does not exist
LINE 1: ...ccountmaster"."id") INNER JOIN "acfs_formats" ON ("acfs_subs...
What could be the reason, What Should I do to solve this. I can't DROP Table. ?
my models.py looks like this :
class SubscriptionMaster(models.Model):
"""
"""
uid = models.TextField(blank=True, null=True)
FK_SubsType = models.ForeignKey(SubscriptionType)
FK_Product = models.ForeignKey(ProductMaster)
FK_Formats = models.ForeignKey(Formats) <<---------------------------------- Added this field in models.py
ccs_minimum_price = models.TextField(blank=True, null=True)
ccs_maximum_price = models.TextField(blank=True, null=True)
ccs_Increment_type = models.TextField(blank=True, null=True)
ccs_minimum_increment = models.TextField(blank=True, null=True)
ccs_maximum_increment = models.TextField(blank=True, null=True)
ccs_default_offer = models.TextField(blank=True, null=True)
Checked SQL Got created by python manage.py sqlall acfs
This is my table :
CREATE TABLE "acfs_subscriptionmaster" (
"id" serial NOT NULL PRIMARY KEY,
"uid" text,
"FK_SubsType_id" integer NOT NULL REFERENCES "acfs_subscriptiontype" ("id") DEFERRABLE INITIALLY DEFERRED,
"FK_Product_id" integer NOT NULL REFERENCES "acfs_productmaster" ("id") DEFERRABLE INITIALLY DEFERRED,
"FK_Formats_id" integer NOT NULL REFERENCES "acfs_formats" ("id") DEFERRABLE INITIALLY DEFERRED, <--------------This field has got created here
"ccs_minimum_price" text,
"ccs_maximum_price" text,
"ccs_Increment_type" text,
"ccs_minimum_increment" text,
"ccs_maximum_increment" text,
"ccs_default_offer" text,
);
Also its howing indexes like this :
CREATE INDEX "acfs_subscriptionformats_FK_Format_id" ON "acfs_subscriptionformats" ("FK_Format_id");
CREATE INDEX "acfs_subscriptionmaster_FK_SubsType_id" ON "acfs_subscriptionmaster" ("FK_SubsType_id");
CREATE INDEX "acfs_subscriptionmaster_FK_Product_id" ON "acfs_subscriptionmaster" ("FK_Product_id");
CREATE INDEX "acfs_subscriptionmaster_FK_Formats_id" ON "acfs_subscriptionmaster" ("FK_Formats_id");
Looks like error is field has not got created in actual database :
python manage.py dbshell
acfsdb1=# SELECT * FROM acfs_subscriptionmaster;
id | uid | FK_SubsType_id | FK_Product_id | ccs_minimum_price | ccs_maximum_price | ccs_Increment_type | ccs_minimum_increment | ccs_maximum_increment | ccs_default_of
