已经挣扎了几个小时,现在试图导入 CSV,使用流星文件从客户端上传,并使用node-csv服务器端转换为 CSV 。我基本上需要用用户上传的 CSV 文件中的数据填充我的集合。
/server/filehandler.js:
Meteor.methods({
'uploadFile': function (file) {
if(file.start === 0) {
console.log(file.name);
console.log(file.type);
console.log(file.size);
}
file.save('/home/russell/tmp',{});
var buffer = new Buffer(file.data);
CSV().from(
buffer.toString(),
{comment: '#', delimiter: ',', quote: ''}
)
.to.array( function(data){
//console.log(data);
for(var row=0; row<data.length; row++) {
console.log(data[row]);
newRecord = {
'firstname': data[row][0],
'lastname': data[row][1],
'email': data[row][2],
'emailshort': data[row][3],
'emailmain': data[row][4],
'domain': data[row][5]
};
console.log(newRecord);
reas.insert(newRecord); // *** _dynamic_meteor ERROR here!
}
} );
} // uploadFile
});
console.log 告诉我 CSV 到数组的转换很好。
集合reas设置为 /lib/models.js 中的集合 - /lib 与 /server 和 /client 处于同一级别。
我尝试在 Meteor.method() 之外使用一个全局变量并将转换结果存储到该变量中,我也尝试过使用 Session.set(),但我似乎无法理解转换的结果,在方法()之外。
谢谢。

我的 /libs/models.js 看起来像这样:
reas = new Meteor.Collection("RegisteredEmailAddresses");
/*checks to see if the current user making the request to update is the admin user */
function adminUser(userId) {
var adminUser = Meteor.users.findOne({username:"admin"});
return (userId && adminUser && userId === adminUser._id);
}
reas.allow({
insert: function(userId, doc){
return adminUser(userId);
},
update: function(userId, docs, fields, modifier){
return adminUser(userId);
},
remove: function (userId, docs){
return adminUser(userId);
}
});
尤里卡时刻?!
那不应该是/lib而不是 /libs 吗?也许没有及时定义reas?

如果我排队
reas.insert(newRecord);
我收到以下错误消息。如果我删除那条线,我不会。
