I try to find the undefined error but no luck. The error occurs when your log in and you click "Create a Taco". I think I need Chris Freeman or Kenneth Love to help me out with this one. Here is the link to hard work of coding. Thanks for taking the time out of your day for helping me. Means a lot to me.

Looking at the database, I don't see "cheese" in the taco model. The fields in the database for taco are "id", "timestamp", "user_id", "content", "user".
$ sqlite3 python.db
SQLite version 3.7.17 2013-05-20 00:56:22
Enter ".help" for instructions
Enter SQL statements terminated with a ";"
sqlite> .dump taco
PRAGMA foreign_keys=OFF;
BEGIN TRANSACTION;
CREATE TABLE "taco" ("id" INTEGER NOT NULL PRIMARY KEY, "timestamp" DATETIME NOT NULL, "user_id" I
NTEGER NOT NULL, "content" TEXT NOT NULL, FOREIGN KEY ("user_id") REFERENCES "user" ("id"));
CREATE INDEX "taco_user_id" ON "taco" ("user_id");
COMMIT;
Removing the database python.db and letting it be reinitialized corrected the database:
treehouse:~/workspace$ sqlite3 python.db
SQLite version 3.7.17 2013-05-20 00:56:22
Enter ".help" for instructions
Enter SQL statements terminated with a ";"
sqlite> .dump taco
PRAGMA foreign_keys=OFF;
BEGIN TRANSACTION;
CREATE TABLE "taco" ("id" INTEGER NOT NULL PRIMARY KEY, "timestamp" DATETIME NOT NULL, "user_id" I
NTEGER NOT NULL, "protein" VARCHAR(100) NOT NULL, "chesse" SMALLINT NOT NULL, "shell" VARCHAR(100)
NOT NULL, "extras" TEXT NOT NULL, FOREIGN KEY ("user_id") REFERENCES "user" ("id"));
CREATE INDEX "taco_user_id" ON "taco" ("user_id");
COMMIT;
sqlite>
After this, it still didn't work. But looking closer at the above output I saw the field name "chesse" (two 's'), which is driven by the model definition:
class Taco(Model):
timestamp = DateTimeField(default=datetime.datetime.now)
user = ForeignKeyField(
rel_model=User,
related_name='tacos'
)
protein = CharField(max_length=100)
chesse = BooleanField() # <-- This "chesse" stands alone!
Fixing the typo and recreating the database, resolved the issue! Good luck with the rest of the challenge!
