私が CouchApp を使用して作成したリスト関数に問題があり、名前であるビューから項目を取得し、その後に ID のハッシュ リストと、ユーザーの CSV ファイルを作成するための値が続きます。
function(head, req) {
// set headers
start({ "headers": { "Content-Type": "text/csv" }});
// set arrays
var snps = {};
var test = {};
var inds = [];
// get data to associative array
while(row = getRow()) {
for (var i in row.value) {
// add individual to list
if (!test[i]) {
test[i] = 1;
inds.push(i);
}
// add to snps hash
if (snps[row.key]) {
if (snps[row.key][i]) {
// multiple call
} else {
snps[row.key][i] = row.value[i];
}
} else {
snps[row.key] = {};
snps[row.key][i] = row.value[i];
}
//send(row.key+" => "+i+" => "+snps[row.key][i]+'\n');
}
}
// if there are individuals to write
if (inds.length > 0) {
// sort keys in array
inds.sort();
// print header if first
var header = "variant,"+inds.join(",")+"\n";
send(header);
// for each SNP requested
for (var j in snps) {
// build row
var row = j;
for (var k in inds) {
// if snp[rs_num][individual] is set, add to row string
// else add ?
if (snps[j][inds[k]]) {
row = row+","+snps[j][inds[k]];
} else {
row = row+",?";
}
}
// send row
send(row+'\n');
}
} else {
send('No results found.');
}
}
?key="something" または ?keys=["something", "another] を使用して _list/mylist/myview (mylist は上記のリスト関数であり、ビューは上記のように返されます) を要求すると、機能しますが、クエリ文字列と私は以下のエラーが発生します:
