[英]Using variables in Cradle Merge (Node.js and CouchDB)
I'm trying to write a function that loops and changes a field in multiple documents at the same time. 我正在尝试编写一个函数,该函数可以同时循环和更改多个文档中的字段。 The only issue is that when I'm passing a parameter value, the cradle merge seems to actually pass a field with the parameter name instead of the value.
唯一的问题是,当我传递参数值时,通讯录合并似乎实际上传递的是带有参数名称而不是值的字段。
For example: 例如:
function saveToAll(field, data) {
db.get('document_list', function (err, doc) {
for (key in doc.doc_list_pure) {
//Create a Closure
(function(key1) {
console.log(key1)
//Go into the DB
console.log(field);
console.log(data);
db.merge(key1, {
field : data
}, function (err, res) {
console.log('Saved');
});
}
)(key)
}
});
}
So here, if I write a function like this: 所以在这里,如果我编写这样的函数:
saveToAll("new_field", value);
It will log correctly, but save a field literally called 'field' with the correct data. 它将正确记录日志,但保存带有正确数据的字面意义为“ field”的字段。 Does anyone have an idea of how to approach this?
有谁知道如何解决这个问题? Is this a cradle bug or just me?
这是一个摇篮虫还是我?
Try this: 尝试这个:
function saveToAll(field, data) {
db.get('document_list', function (err, doc) {
for (key in doc.doc_list_pure) {
//Create a Closure
(function(key1) {
console.log(key1)
//Go into the DB
console.log(field);
console.log(data);
var dataObj = {};
dataObj[field]=data;
db.merge(key1, dataObj, function (err, res) {
console.log('Saved');
});
}
)(key)
}
});
}
