Question

我使用100000将record push RangeError: Maximum call stack size exceeded插入firebase数据库，

但我收到的错误如下：

   for (var i = 0; i < unamelist.length; i++) {
        var uname = unamelist[i];

        var Actionref = firebase.database().ref("Actionusers/" + mkey);
        var newData = {
            Actiontype: 3,
            status: true,
            Iscompleted: 0,
            username: uname.toLowerCase(),
            datetime: firebase.database.ServerValue.TIMESTAMP
        }

        Actionref.push(newData,function (error) {
                if (error) {
                    console.log('Error while push Action users from excel: ' + error)
                }
                else{
                    var testActionref = firebase.database().ref("Actionusers/" + mkey);
                    testActionref.once('value').then(function (snap) {
                        var stupdateref1 = firebase.database().ref('Msgtemplate/' + mkey);
                        stupdateref1.update({
                            Rest: snap.numChildren()
                        })
                    })
                }

            })
    }

我的代码如下：

fatal: Not a git repository (or any of the parent directories): .git

Thanx @frank for quik look，

我只是通过下面的代码来解决我的问题：

    for (var i = 0; i < unamelist.length; i++) {
        var uname = unamelist[i];
        console.log(uname);

        var Actionref = firebase.database().ref("Actionusers/" + mkey);
        var newData = {
            Actiontype: 3,
            status: true,
            Iscompleted: 0,
            username: uname.toLowerCase(),
            datetime: firebase.database.ServerValue.TIMESTAMP
        }

        Actionref.push(newData)

        if (i == (unamelist.length-1)) {
           Actionref.once('value').then(function (snap) {
            var stupdateref1 = firebase.database().ref('Msgtemplate/' + mkey);
            stupdateref1.update({
                Rest: snap.numChildren()
            })
           })
        }
    }

我想当我每次在不同节点中更新Actionusers时将数据推送到Rest时，这就是为什么数量非常大的呼叫数量。要解决此问题，我只需在完成for循环后更新Rest并解决我的问题。

如何一次将数据束推入firebase数据库
