Hi,
I have the following model.
class Tag(Entity):
tag=Field(String,unique=True)
class Link(Entity):
address=Field(String)
tags=ManyToMany('Tag')
Let's say I execute the following instructions:
Link(address='http://
www.google.com',tags=[Tag(tag='search'),Tag(tag='engine')])
session.commit()
In this moment (if everything goes as expected) my model_tag table has
two entries search and engine and also the model_link has one record,
the google page.
Now let's say that I want to add another link. Now is the place where
my issue starts.
Link(address='http://
www.yahoo.com',tags=[Tag(tag='search'),Tag(tag='site')])
session.commit()
The problem is that in this form, Elixir will try to insert into the
tags table another entry of the 'search' tag, which is unacceptable
due to the unique constraint. I would like to know how to tell Elixir
to fetch transparently the id of the 'search' tag and add it to the
realation table for address-tag.
Thank you,
Mihai
