this is my coding in controller
def simpan(){
def banklimit = new BankLimit()
for(int i = 0; i<params.limitPerDay.size();i++) {
def baaa = CurrencyList.list(params)
banklimit.dayLimit = params.limitPerDay[i].toBigDecimal()
banklimit.alertLimit = (banklimit.dayLimit*0.8)
banklimit.currency = CurrencyList.findBySym(baaa.sym[i])
banklimit.save()
}
return banklimit
}
<table>
<thead>
<tr>
<g:sortableColumn property="sym" title="${message(code: 'banklimit.currency.sym.label', default: 'Simbol')}" />
<g:sortableColumn property="limitday" title="${message(code: 'banklimit.dayLimit.label', default: 'Limit/Day')}" />
</tr>
</thead>
<tbody>
<g:each in="${aaa}" status="i" var="bbb">
<tr class="${(i % 2) == 0 ? 'even' : 'odd'}">
<td id="${bbb.id}"> ${fieldValue(bean: bbb, field: "sym")}</td>
<td id="${bbb.id}" colspan="2"> <g:textField name="limitPerDay" value="${value}" /></td>

i want to save the field on coloum limit /day if i click "SAVE" buttons.
based my coding, when i click save, only the last row was save in database...
example : theres 4 row..
row 1,2,3,4 filled, then i click save..why only 4th rows save in database? row 1 ,2,3 arenot saving?

Answer 1

You have just one banklimit = new BankLimit() but saving it 4 times. it's one object saved 4 times with different values in loop.
You need:
for(int i = 0; i<params.limitPerDay.size();i++) {
def banklimit = new BankLimit()
//.... fill with values
banklimit.save()
}
For client side it's better to make:
<g:each in="${aaa}" status="i" var="bbb">
<tr class="${(i % 2) == 0 ? 'even' : 'odd'}">
<td>${fieldValue(bean: bbb, field: "sym")}</td>
<td colspan="2"><g:textField name="limitPerDay[${i}]" value="${value}" /></td>
</tr>
</g:each>
