how to add a row in google spreadsheet and reference another cell? - google-apps-script

Question

I'm trying to create a function to pull data from google finance and have it automatically log data to multiple sheets of a document. I can't seem to get it to add a function as a function it always adds it as text until i edit the cell
function addLog() {
var sheet = SpreadsheetApp.getActiveSheet();
var rows = sheet.getDataRange();
var numRows = rows.getNumRows();
var numLastRows = rows.getLastRow();
sheet.appendRow(['2012/10/28','=b92','=c92','Log (auto)','','=index(GoogleFinance(C92,"price",A92);2;2)','','=h92','=i92','=j92','=k92']);
};
i couldn't figure out how to make it reference the cell above (row 92 in this case) either :(

You will need to use the setFormula() method rather than appendRow(). Perhaps something like:
function addLog() {
var sheet = SpreadsheetApp.getActiveSheet();
var numLastRow = sheet.getLastRow();
//add a row at end if necessary
if (sheet.getMaxRows() == numLastRow) sheet.insertRowAfter(numLastRow);
sheet.getRange(numLastRow + 1, 2, 1, 10)
.setFormulas([['=b' + numLastRow,
'=c' + numLastRow,
'',
'',
'=index(GoogleFinance(C' + numLastRow + ',"price",A' + numLastRow + ');2;2)',
'',
'=h' + numLastRow,
'=i' + numLastRow,
'=j' + numLastRow,
'=k' + numLastRow]]);
sheet.getRange(numLastRow + 1, 1).setValue('2012/10/28');
sheet.getRange(numLastRow + 1, 4).setValue('Log (auto)');
}
To perform this action from the xth sheet through to the yth sheet (using zero-based index), I think the most efficient way would be:
function addAllLog() {
var sheets = SpreadsheetApp.getActive().getSheets();
var x = 1;
var y = 34;
for (var i = x; i <= y; i++) {
addLog(sheets[i]);
}
}
function addLog(sheet) {
var numLastRow = sheet.getLastRow();
//add a row at end if necessary
if (sheet.getMaxRows() == numLastRow) sheet.insertRowAfter(numLastRow);
sheet.getRange(numLastRow + 1, 2, 1, 10)
.setFormulas([['=b' + numLastRow,
'=c' + numLastRow,
'',
'',
'=index(GoogleFinance(C' + numLastRow + ',"price",A' + numLastRow + ');2;2)',
'',
'=h' + numLastRow,
'=i' + numLastRow,
'=j' + numLastRow,
'=k' + numLastRow]]);
sheet.getRange(numLastRow + 1, 1).setValue('2012/10/28');
sheet.getRange(numLastRow + 1, 4).setValue('Log (auto)');
}
