I'am currently playing around with the Couchbase Sync-Gateway and have built a demo app.
What is the intended behavior if a user logs in with the same username on a different device (which has an empty database) or if he deleted the local database?
I'am expecting that all the data from the server should get synced back to the clients.
Is this correct?
My problem is that if i'am deleting the database or login from a different device, nothing will get synced.
Ok i figured it out and it's exactly how i thought it would be.
If i log in from a different device i get all the data synced automatically.
My problem was the missing sync function. I thought it will use a default and route all documents to the public channel automatically.
I'am now using the following simple sync-function:
"sync": `function (doc, oldDoc) {
channel('!');
access('demo#example.com', '*');
}`
This will simply route all documents to the public channel and grant my demo-user access to it.
I think this shouldn't be used in production but it's a good starting point for playing around.
Now everything is working fine.
Edit: I've now found the missing info:
https://docs.couchbase.com/sync-gateway/current/configuration-properties.html#databases-this_db-sync
If you don't supply a sync function, Sync Gateway uses the following default sync function
...
The channels property is an array of strings that contains the names of the channels to which the document belongs. If you do not include a channels property in a document, the document does not appear in any channels.
i believe that in google API version 2, it could eventually call this method out. Moreover they do share or happen to be using the same type of coding.
However in version 3, i could not set this layer to the map neither via "layer.setMap(map)" because this esri method does not has this function , nor "map.addOverlay(layer)" because this function belongs to version 2 which has been taken down. can i ask what is the method replacing "map.addOverlay(layer)" in version 3. i have try using custom overlay function, but is comes out as a image which doesn't match the result i want.
** take note : ArcGISDynamicMapServiceLayer is to call a time aware data layer from esri
Have a look at these examples:

Good Evening!
I've been looking into the possibility of using GAS(Google Apps Script) to host a small bit of javascript that lets me use the new Google finance apps api. The intention being that I'll be using the stock information for a project which involves the use of stock data. I know that there are a few ways to get stock information from Google, but the data that the finanace app returns is more in-line with other sources we are using. (One constraint on this project is that we have multiple sources).
I've written the javascript and I can call a httpc:request to the URL for the script given to me from Google. In the browser the JS returns the json object as I want it, however when the call is made from Erlang I'm getting it in a list of ascii. From checking the values it appears to be a document starting like:
Below is the javascript and the url to see the json:
https://script.google.com/macros/s/AKfycbzEvuuQl4jkrbPCz7hf9Zv4nvIOzqAkBxL1ixslLBxmSEhksQM/exec
function doGet() {
var stock = FinanceApp.getStockInfo('LON:TSCO');
return ContentService.createTextOutput(JSON.stringify(stock))
.setMimeType(ContentService.MimeType.JSON);
}
For the erlang, it's a simple request but I've not been doing erlang long, so perhaps I've messed something up here (The URL being the one mentioned above). I've got crypto / ssl / inets when I'm testing this on the command line.
{ok, {Version, Headers, Body}} = httpc:request(get, URL, []}, [], []).
I think it's also worth mentioning that when i curl it from Cygwin, I get a massive load of HTML also, I've included it below, but if you see it you'll thank me for not posting it in here! http://pastebin.com/UtJHXjRm
I've been updating the script as I go with the new versions but I'm at a bit of a loss as to why it's not returning correctly.
If anyone can give me any pointers I'd be very grateful! I get the feeling that it's not intended to be used this way, perhaps only within other Google products and such.
Cheers!
It would be necessary to review how are you deploying the Web App, specifically the Who has access to the app, to access without authentication should be configured as shown in the image:
See Deploying Your Script as a Web App from the documentation.
In my test, by running:
curl -L https://script.google.com/macros/s/************/exec
Get the following result:

Possibly your GET is not following the REDIRECT that happens when you use contentService. Look at the html returned there is a redirect in there.
Im creating an app that needs to track the location of the user (with their knowledge, like a running app) so that I can show them their route later. Should I use HTML5 with some timeout interval to save the coordinates every N seconds and if so, how often should I save the data and how should I save it (locally using local storage or post it to the server?)
Also, what is the easiest way to display the map of where the user has been later?
Has anyone done anything like this before?
The timeout interval for forge.geolocation is up to you and the balance of responsiveness of your application. Also, network traffic is expensive. So maybe you can buffer... say the last 10 geopositions... and then Http post (or whatever... see Parse below) in bulk? And since the geo data sounds like temporary device data why would there be a need to persist using forge.prefs? Unless maybe you need to the app to work "offline"?
For permanent storage I would look at Parse (generous free plan) and their Parse.GeoPoint class via their Javascript or REST Api as one possible solution. They have some nifty methods like (kilometersTo, milesTo, radiansTo) - https://parse.com/docs/js/symbols/Parse.GeoPoint.html
I am displaying a draggable directions google map. when i drag a way point is created and the directions_changed event is fired.
i use DirectionsRenderer.directions to save the way points in the database.
I parsed the names of the objects and properties and i got the following
status: OK; routes: [object Object];
Jf: [object Object]; Xg: true;
In the above the object Jf is the one which is having the waypoints but periodically that name Jf is changing and making us hard to find which property holds the waypoints. I have a method to find that. but yet i want to know how to handle this.
Jf: [object Object]; // here Jf is
changing periodically
I used firefox to debug the object using console.log.
Hope i have made it clear.
The waypoints will be part of the steps of the routes object.
Just one extra note, if order does matter for you then you need to keep an eye on the waypoint_order field if you used the optimize:true argument. Since this will return the optimized path. Reference.
