Hi,
here is some code, that should write and read some tags, it is a slightly
different version as the code in the book (5th Edition) on page 316:
The write test works, but I do not get the handle to read it back. What is
wrong with this code, marked in read?
Thanks for your help!
Cheers!
pd
def writeTagTest():
a = db.tag.insert(name='red')
b = db.tag.insert(name='green')
c = db.tag.insert(name='blue')
db.product.insert(name='Test Toy Car',tags=[a, b, c])
return dict(message="Insert ok", tag=db.tag,product=db.product)
def readTagTest():
b=db(db.tag.name=='green').select().first() #
gluon.dal.Rows?
products = db(db.product.tags.contains(b)).select() # here
products is empty? Why??
for item in products:
print item.name, item.tags
return dict(b=b,product=db.product,products=products)
