I am just getting started with Google Web Toolkit and Google App Engine and have a quick question. I think I understand how to use the datastore now but I was wondering if there is a way that I can quickly create a "database" with static data from an excel sheet? I just need to add some data for a proof of concept later this week.
I am picturing something similar to a SQL database browser where I can just import the data?
I developing in Eclipse with appropriate plugins.
Thanks,
Rob
The easiest way to do this would be to save your spreadsheet as a CSV file, then use the bulkloader to load it into the datastore.
Your best bet is probably to write something to handle uploading it, or to handle processing it on the server.
However, you should also look at the bulk loader. It might be able to save you a little bit of time.
Here is the API (Google Documents List API) that "allows client applications to programmatically access and manipulate user data stored with Google Documents".

Is there a way to create a new Datastore entity kind via some interactive means for Go App Engine apps? The datastore viewer won't let me add new entity kinds, and the interactive console doesn't seem to support Go.
I'm trying to upload some configuration data to datastore, including sensitive data that I don't want to appear in code. So far the best method I can come up with is to write some code to write an empty configuration entity, deploy, run, then use the datastore viewer to set the values.
Thanks in advance.
You absolutely can add new Entity Kinds in the Console.
In the Cloud Console, Click on the Datastore menu item, then 'Create an Entity'. Handy link, just select your project name
Then in the Kind field, just type in your desired Kind name.
First of all your code is safe at AppEngine - nobody can download it. At least nobody outside of Google. You can deploy it to a dedicated version/module and restrict usage to yourself (check current user, ask pass-phrase, etc in your code).
Second you can use Remote API - this way you do not upload any code to AppEngine. You can create entities remotely as you wish using secure HTTPS connection.
I'm quite new to Google App Engine and it's cloud Datastore which is used for storing the backend's data by default. As far as I realized you can only view it's content within the developer console and you can create or edit entities there.
But is there any external tool from which you can connect to your datastore to create reports or administer the data? What is your experience?
In fact yes it's true you can only see data's from the admin console.
If you wish to see your data's in Google Drive Table and make a report you can, but for that you need to create a connector to your sheet (I already made one). It's exactly the same if you need update or import data's to your datastore.
I use this Technic to upload or refresh products on my e-shop GAE app.
In general if I need to see a report, I design a specific web page for that and I protect theme via a login / password. To see a well formatted report you can use jquery library or use Google Charts
Im building a simple angular application and there is a small administrator panel for updating the content (a .json document). I'm looking for a way to edit the json document from the administrator panel.
I can manipulate the memory-loaded json but I can't save it. Is there a way to put the json file in some kind of cloud database and connect to it without setting up a server or backend for my application?
I want my application to be easily deployable on any ftp so I can't setup a nodeserver or install something like couchdb.
Any ideas are appreciated.
You could use a provider like Parse. It's free (up to a limit of requests/month), has a nice JavaScript SDK that would get you up and running quickly. https://parse.com/
Also, check out this query builder to aid in retrieving your data from Parse. It's built as an Angular service for easy integration. https://github.com/dpollot/parse-query
EDIT
Parse also offers hosting, for free.
I m experimenting with GAE, and I m looking for a way to import an .sql file in app engine datastore. I found on GAE site ways to import CSV ans xml files:
https://developers.google.com/appengine/docs/python/tools/uploadingdata
but nothing about .sql.
I ve also came across the so called "jiqlAdmin Data Querying tool" that claims to import .sql files in google `s datastores:
https://groups.google.com/forum/?fromgroups=#!topic/google-appengine-java/Sfy3jmWhYfI
Anybody has tried tool this? Does it work? Do you have any other suggestion?
Thnx
If the goal is just using SQL with App Engine, I would check out Google Cloud SQL, which works great with App Engine.
If you just want your data in the datastore, converting it to CSV and uploading it as per the first link might be a good choice. This will not work if you have things like foreign keys as they will refer to IDs in your old SQL database. You also probably won't be happy with your data if it's arranged in such a way that using a JOIN is the only way to make sense of it.
Since it sounds like you are just getting started, I think Google Cloud SQL is the better option.
Is it possible to get a data source URL of Google Spreadsheets for appengine datastore entities? I want to use the google visualization query objects to query my datastore. Or how I an expose my datastore with a datasource URL.
And for a Google visualization based project which one is better between Google Spreadsheet and GAE big table. Since Google Spreadsheet has very good query options and a nice harmonics with google visualization. One can get a direct DataTable from a data source URL. To do the same thing needs a good amount of task with GAE big table. Please share your experience in this area.
There's nothing built in to do this. You'll need to write your own code that returns your data in a format GViz supports.
