Meteor-Community-Packages
no data (noob question perhaps)
Hi I'm able to retrieve data using peerlibrary:aws-sdk, however when I try to read files using cfs:s3 it returns nothing (no data) I've spent days trying to debug this (including turning on FS Debug) but I still get nothing
Here's my server side code and server log using a known good settings and bucket.
By the way my aws user has full s3 access.
Any help greatly appreciated.

var imageLargeStore = new FS.Store.S3("imagesLarge", {
accessKeyId: Meteor.settings.AWS.accessKeyId,
secretAccessKey: Meteor.settings.AWS.secretAccessKey,

var imageSmallStore = new FS.Store.S3("imagesSmall", {

secretAccessKey: Meteor.settings.AWS.secretAccessKey,
bucket: "salk-employee-pics",
transformWrite: function(fileObj, readStream, writeStream) {
gm(readStream, fileObj.name()).resize('80', '80').stream().pipe(writeStream)
}
});
thumbs = new FS.Collection("images", {
stores: [imageLargeStore,imageSmallStore]

console.log(thumbs.find());

Am I missing anything for having a well formed description of the problem?
try..
console.log(thumbs.find().fetch())
instead of
console.log(thumbs.find())
Hi, I tried your suggestion and still no data. Question, is it possible to use cfs:s3 on data that is already in a bucket? Or, do I have to use the cfs:s3 methods to upload data to the bucket and generate necessary metadata? Many Thanks
I personally have no s3 account and am not so familiar with this particular s3:package, but i would assume there has to be some metadata in a mongo collection somewhere (like in the other cfs:stores), if you want to perform mongo queries on your files. A store is just there to write and delete files.
You could either use the common cfs storage adapter server insert method Images.insert(path||url) or generate the required metadata yourself somehow. I would suggest testing with an empty/test bucket first ;)
https://github.com/CollectionFS/Meteor-CollectionFS/blob/master/packages/storage-adapter/internal.api.md#selfinsertfsfile-options-callbackserver
I ended up using peerlibrary/meteor-aws-sdk to load the data from s3 into this package's adaptor (cfs:s3). Feeling like it's not a great solution, but may have to be good enough for now.
And, I used the insert method you recommended. Here' what I ended up with: ` updateEmployeeThumbs: function(){
var configObj = {
"accessKeyId": Meteor.settings.AWS.accessKeyId,
"secretAccessKey": Meteor.settings.AWS.secretAccessKey,
"bucket": "salk-employee-pics"
};
var updateCollectionFs = function(listDataContents){
_.each(listDataContents,(chunk)=>{
_.each(chunk,(f)=>{
var e = EmployeeThumbs.findOne({'original.name':f.Key});
//for now only insert what's missing, don't update
if(typeof e == 'undefined' ){
console.log('here is supposed to be contents for insert');
console.log(f);
s3 = new AWS.S3();
AWS.config.update({
"accessKeyId": configObj.accessKeyId,
"secretAccessKey": configObj.secretAccessKey,
"bucket": configObj.bucket
});
var readStream = s3.getObjectSync({
"Key":f.Key,
"Bucket":"salk-employee-pics"}
);
// You must have a ReadStream with some data; it can be any stream.
// We're using the standard output from a command as an example.
//var readStream = spawn('ls', []).stdout;
// Create the FS.File instance
var newFile = new FS.File();
// Attach the ReadStream data to it.
newFile.attachData(readStream.Body, {type: 'image/jpeg'});
// Optionally provide a file name
newFile.name(f.Key);
// Insert the file, which will save the metadata and
// store the stream data into all defined stores.
// `Files` is an `FS.Collection` instance defined elsewhere.
var thumb = EmployeeThumbs.findOne({'original.name':f.Key});
if(typeof thumb !== 'undefined'){
console.log('reloading thumb for '+f.Key);
EmployeeThumbs.update({'original.name':f.Key},newFile);
} else{
console.log('inserting new thumb for '+f.Key);
EmployeeThumbs.insert(newFile);
}
}
});
});
};
var allKeys = [];
var listAllObjectsFromS3Bucket = function(configObj,marker){
AWS.config.update({
"accessKeyId": configObj.accessKeyId,
"secretAccessKey": configObj.secretAccessKey,
"bucket": configObj.bucket
});
s3 = new AWS.S3();
var list = s3.listObjectsSync({Bucket: configObj.bucket, Marker: marker});
allKeys.push(list.Contents);
console.log('pushed list of '+ list.Contents.length);
//console.log(list);
if(list.IsTruncated){
console.log('list was truncated, doing it again before upsert');
var contents = list.Contents;
var marker = contents[contents.length-1].Key;
console.log('next marker is:'+marker);
listAllObjectsFromS3Bucket(configObj,marker);
} else {
return allKeys;
}
};
listAllObjectsFromS3Bucket(configObj,'');
//console.log('here is the allKeys listing:');
//console.log(allKeys);
console.log('now going to upsert');
updateCollectionFs(allKeys);
