I've been working on the famo.us Slideshow tutorial and realised that the API is no longer working.
Any ideas how can I still make this to work without the Picasa API?
You can keep the API by using the following code for SlideData.js
You can make it work by creating the objects returned by the url + parameters below and returning them as the JSON object if you do not want to use the API.
define(function(require, exports, module) {
var SlideData = {
picasaUrl: 'https://picasaweb.google.com/data/feed/api/all',
queryParams: '?kind=photo&q=puppy&max-results=5&imgmax=720&alt=json',
defaultImage: 'https://lh4.googleusercontent.com/-Roszbra0TlI/VB-fE83NAXI/AAAAAAAAACU/ITmhyZMHZrk/s720/cute%252520looking%252520white%252520and%252520black%252520french%252520Bulldog%252520Puppy.jpg'
};
SlideData.getUrl = function() {
return SlideData.picasaUrl + SlideData.queryParams;
};
SlideData.parse = function(data) {
var urls = [];
data = JSON.parse(data);
var entries = data.feed.entry;
for (var i = 0; i < entries.length; i++) {
var media = entries[i].media$group;
urls.push(media.media$content[0].url);
}
return urls;
};
module.exports = SlideData;
});

I'm a new to Ember and am having a really hard time with this problem. I'm building an app that manages beer tap lists. Each bar has a different number of taps.
I take the number of taps in the new bar signup = orgTap
On the first login to the dashboard I want to have an empty line for each tap and a db entry created to correspond to each tap.
The code I have is:
export default Ember.Route.extend({
model(params) {
return this.get('store').findRecord('bis', params.bis_id);
},
actions: {
generateTapList(orgTap, id){
var store = this.store;
let tapOwner = this.get('store').peekRecord('bis', id);
const taps = this.get('orgTap');
let i = orgTap;
const newTap = store.createRecord('taplist', {
bis: tapOwner,
{{HOW DO I LOOP???}}
tap: "Tap" + i,
i = i - 1;
{{/HOW DO I LOOP???}}
});
newTap.save();
},
}
});
I have installed ember-truth-helpers thinking it may help with the loop.
Side Question -- Am I stupid for trying to learn Ember for my first app after a full stack dev class?? I feel that everything I just learned is irrelevant to how Ember works.
Solution:
generateTapList(orgTap, id){
var store = this.store;
let tapOwner = this.get('store').peekRecord('bis', id);
var tablistProps = {};
var i = 0;
tablistProps['bis'] = tapOwner;
while (i < orgTap){
i++;
tablistProps = {tap: "tap" + i, tapBeer: ""};
const newTap = store.createRecord('taplist', tablistProps)
newTap.save();
}
},
as the title suggests, I am trying to read the contents of a simple text file using JSOM. I am using a Sharepoint-hosted addin for this, the file I am trying to read resides on the host web in a document library.
Here's my JS code:
function printAllListNamesFromHostWeb() {
context = new SP.ClientContext(appweburl);
factory = new SP.ProxyWebRequestExecutorFactory(appweburl);
context.set_webRequestExecutorFactory(factory);
appContextSite = new SP.AppContextSite(context, hostweburl);
this.web = appContextSite.get_web();
documentslist = this.web.get_lists().getByTitle('Documents');
var camlQuery = new SP.CamlQuery();
camlQuery.set_viewXml('<View><ViewFields><FieldRef Name="Name"/></ViewFields></View>');
listitems = documentslist.getItems(camlQuery);
context.load(listitems, 'Include(File,FileRef)');
context.executeQueryAsync(
Function.createDelegate(this, successHandler),
Function.createDelegate(this, errorHandler)
);
function successHandler() {
var enumerator = listitems.getEnumerator();
while (enumerator.moveNext()) {
var results = enumerator.get_current();
var file = results.get_file();
//Don't know how to get this to work...
var fr = new FileReader();
fr.readAsText(file.get);
}
}
function errorHandler(sender, args) {
console.log('Could not complete cross-domain call: ' + args.get_message());
}
}
However, in my succes callback function, I don't know how I can extract the contents of the SP.File object. I tried using the FileReader object from HTML5 API but I couldn't figure out how to convert the SP.File object to a blob.
Can anybody give me a push here?
Once file url is determined file content could be loaded from the server using a regular HTTP GET request (e.g. using jQuery.get() function)
Example
The example demonstrates how to retrieve the list of files in library and then download files content
loadItems("Documents",
function(items) {
var promises = $.map(items.get_data(),function(item){
return getFileContent(item.get_item('FileRef'));
});
$.when.apply($, promises)
.then(function(content) {
console.log("Done");
//print files content
$.each(arguments, function (idx, args) {
console.log(args[0])
});
},function(e) {
console.log("Failed");
});
},
function(sender,args){
console.log(args.get_message());
}
);
where
function loadItems(listTitle,success,error){
var ctx = SP.ClientContext.get_current();
var web = ctx.get_web();
var list = web.get_lists().getByTitle(listTitle);
var items = list.getItems(createAllFilesQuery());
ctx.load(items, 'Include(File,FileRef)');
ctx.executeQueryAsync(
function() {
success(items);
},
error);
}
function createAllFilesQuery(){
var qry = new SP.CamlQuery();
qry.set_viewXml('<View Scope="RecursiveAll"><Query><Where><Eq><FieldRef Name="FSObjType" /><Value Type="Integer">0</Value></Eq></Where></Query></View>');
return qry;
}
function getFileContent(fileUrl){
return $.ajax({
url: fileUrl,
type: "GET"
});
}
What i'm doing is loading Ids from my Parse database and for each Id I want to call a httpRequest to Facebook Api. The problem is that httpRequest seems to not work when there is not a response.success (it ends the proccess) call inside itself.
This is what I have so far:
Parse.Cloud.define("hello", function(request, response) {
var query = new Parse.Query("Location");
query.find({
success: function(results) {
console.log(results);
for (var i = 0; i < results.length; ++i)
var locationId = results[i].get("locationId");
console.log(locationId);
Parse.Cloud.httpRequest({
url: 'https://graph.facebook.com/v2.2/'+locationId+'/events?access_token='+accessToken,
success: function(httpResponse) {
console.log(httpResponse.data);
response.success("result");
},
error:function(httpResponse){
console.error(httpResponse.message);
response.error("Failed to login");
}
});
...
Any ideas?
I'm not the most up on my javascript, but I'm pretty sure this is the concept you're looking for. It's possible better solutions exist.
var totalResults = results.length;
var completedResults = 0;
var completion = function() {
// Because you're doing multiple requests, you'll need to figure out how you determine success/failure. ie: Are any failures considered an overall failure? Do you want to pass a more detailed success?
response.success("Finished");
};
for (var i = 0; i < totalResults; ++i)
var locationId = results[i].get("locationId");
console.log(locationId);
Parse.Cloud.httpRequest({
url: 'https://graph.facebook.com/v2.2/'+locationId+'/events?access_token='+accessToken,
success: function(httpResponse) {
completedResults++;
console.log(httpResponse.data);
if (completedResults == totalResults) {
completion();
}
},
error:function(httpResponse){
completedResults++;
console.error(httpResponse.message);
if (completedResults == totalResults) {
completion();
}
}
});
}

I'm having a difficult time returning data from a module using RequireJS and Knockout to populate my markup for my single page app. Knockout can't seem to find my data binding observables.
I'm trying to keep each view in a separate js file, but I'm failing to identify where I've gone wrong. Here's what I have so far:
/app/app.js
define(function(require) {
require('simrou');
var $ = require('jQuery'),
ko = require('knockout'),
videoView = require('videoView');
var init = function() {
var viewModel = function() {
var self = this;
self.currentPage = ko.observable();
self.videoView = new videoView();
}
var view = new viewModel();
ko.applyBindings( view );
_router = new Simrou({
'/video/:id': [ view.videoView.getVideo ]
});
_router.start();
};
return {
init: init
};
});
/app/videoView.js
define(function(require) {
"use strict";
var $ = require('jQuery'),
ko = require('knockout');
return function() {
var self = this;
self.currentPage = ko.observable( 'showVideo' );
self.currentVideo = ko.observable();
self.videoData = ko.observableArray([]);
self.videoList = ko.observableArray([]);
var getVideo = function( event, params ) {
// ajax pseudo code
$.ajax({});
self.videoData( dataFromAjaxCall );
}
return {
getVideo: getVideo
};
};
});
index.html
When I browse to /#/video/14 I receive the following error:
Uncaught ReferenceError: Unable to parse bindings.
Bindings value: attr: { 'data-video-id': videoData().id }
Message: videoData is not defined
Here's the markup:
<section id="showVideo" data-bind="fadeVisible: currentPage()=='showVideo', with: $root">
<div class="video" data-bind="attr: { 'data-video-id': videoData().id }></div>
</section>
Like I said, I'm trying to keep each view separated, but I would love some enlightenment on what I'm doing wrong, or if this is even possible? Is there a better more efficient way?
videoData is a property of $root.videoView, not of the root model (the one you passed to applyBindings). It's also an observableArray, so videoData() is just a plain array and even if you get the context right, you won't be able to access its id property, since, being an array, it doesn't have.named properties.
This must be close but I can't figure out what's causing the error.
In my Titanium app, I have a Webview with a canvas element and this code:
function getImageData() {
return canvas.toDataURL('image/png');
}
I am moving that data to the Titanium app like this:
var imageBase64data = webview.evalJS('getImageData()')
The data looks good starting with "data:image/png;base64,"...
Then in Titanium, I have a logged-in drupal session and call this function:
function uploadImage(imageBase64data, callback) {
var url = REST_PATH + "file.json";
var file = {
filename: utils.createRandomString() + ".png",
file: imageBase64data
// uid: Titanium.App.Properties.getString("userUid"),
// filesize: ""+Titanium.Utils.base64decode(imageBase64data).length,
};
var xhr = Titanium.Network.createHTTPClient({timeout: 30000});
xhr.setRequestHeader("Content-Type", "application/json; charset=utf-8");
var authString = Titanium.App.Properties.getString("userSessionName")+'='+Titanium.App.Properties.getString("userSessionId");
xhr.setRequestHeader("Cookie", authString);
xhr.onload = function() {
if(xhr.status == 200) {
var response = xhr.responseText;
callback(response);
}
};
xhr.onerror = function(e) {
alert("There was an error: " + e.error);
Ti.API.info(JSON.stringify(this));
};
xhr.open("POST", url);
xhr.send(file);
}
xhr.onerror is being called with e.error = "undefined"
The trace looks like this:
{
"responseData":{},
"readyState":4,
"connected":true,"UNSENT":0,"DONE":4,"HEADERS_RECEIVED":2,"OPENED":1,"LOADING":3,
"responseText":null,"status":406
}
I think authentication is working because I was previously getting a "need authentication" error until I added the Cookie header.
That was with the installation provided by Drupanium. I just did a fresh Drupal and fresh Services 3 install and my file is uploading nicely.
