I am trying to show the detail for a foreign key, but I really do not
know how to do it.
My model is:
db.define_table('currency',
SQLField('code',length=3),
SQLField('name',length=100))
db.currency.code.requires=[IS_NOT_EMPTY(),IS_NOT_IN_DB
(db,'currency.code')]
db.currency.name.requires=[IS_NOT_EMPTY(),IS_NOT_IN_DB
(db,'currency.name')]
db.define_table('bank',
SQLField('name', length=150)
)
db.define_table('cash_account',
SQLField('name', length=150),
SQLField('bank', db.bank),
SQLField('currency', db.currency)
)
My controler is
def list_banks_and_accounts():
banks=db().select(db.bank.ALL,orderby=db.bank.name)
return dict(banks=banks)
My view is:
{{extend 'layout.html'}}
<h1>This is the test/list_banks.html template</h1>
<BR/>
<a href="/{{=request.application}}/bank/new_bank"><button
type="button">Create new bank</button></a>
<a href="/{{=request.application}}/bank/
new_bank_account"><button type="button">New bank account</button></a>
</b>
<BR/>
{{for bank in banks:}}
<b><TR> <a href="/{{=request.application}}/bank/edit_bank/
{{=bank.id}}">{{=bank.name}}</a> </TR> <br/>
{{cash_accounts = db(db.cash_account.bank==bank.id).select()}}
{{for cash_account in cash_accounts:}}
<TR> {{=cash_account.currency}} {{=cash_account.name}}</
TR> <a href="/{{=request.application}}/bank/edit_bank_account/
{{=cash_account.id}}"><button type="button">Edit</button></a><br/>
{{pass}}
<br/>
{{pass}}
What I would like to see is the currency code ("USD", "GBP",
"JPY"....) instead of the foreign key id (an integer).
How can I show the currency code, instead of the foreign key id
{{=cash_account.currency}}?
