So I started to play with Google Mobile Backend Starter.
Now I want to clean this instance and anything that this starter thingy created into the project (e.g. task queues, data store, etc...)
How do we achieve this?
Is this done through some command line somewhere along the lines described in this page?
appengine-java-sdk/bin
EDIT: I should have made it clearer, I don't intend to delete the project. I just want to "clean" it and replace with my own application. Anyway, I ended up using the appengine SDK tools mentioned above (Updating and Managing a Java App). It was a long process, and tedious. It could be improved.
What I did:
Using the appengine SDK tool, downloaded the application first. It prompted me for a password. I had to create a new "App Password" entry in my Google account, since it didn't accept my "usual" Google password (e.g. GMAIL)
To clean the Scheduled Tasks, edit cron.xml so that no entries are left. A sample empty cron.xml file is shown in the documentation page. Run the update procedure of the SDK tool for cron jobs
To clean the Queues, use the same approach (queue.xml)
Clean DataStore by going to DataStore Admin page (if applicable)
Upload your new application (either thru SDK, or thru Android/Eclipse AppEngine plugin)
There will now be 2 (or more) versions of your AppEngine. If necessary, make your newly uploaded application, the default version. This is done in the Developer Console.
Check the instances as well. Remove if necessary

My website changes every day - I run a news website with new stories every day. I want Google to index my site as often as possible and want/need to autogenerate the sitemap.
I use Google App Engine (with Node.js) to run my site. With GAE - I do not have write-access to the root directory. To post the site map - I need to re-deploy my whole site after generating the map. That is an unnecessarily complex step.
I have searched far and wide and cannot see how to save my sitemap. So - I considered using a static one with a dynamically generated child that I store in another location where I have write access. Google says it wants all linked sitemaps in the same directory. So that appears to be a dead-end.
Can I use "App Deploy" in such a way that only the sitemap is uploaded? Any other possibilities? Appreciate any and all suggestions. It seems unlikely that Google didn't provide some way to solve this.
For a site where new URLs are being created regularly (like a news, blog site, etc), don't 'store' your sitemap. It should be generated on demand i.e. your App should include code to generate the content when the link <your_website>/sitemap.xml is loaded.
Separately, you should note that gcloud app deploy doesn't always deploys all your files. It usually deploys only files that have changed. You can easily confirm this by running the deploy command, changing a single file and then running the deploy command again. You will see that the logs will say something like - Uploading 1 files to Google Cloud Storage and the deploy will be faster. You can change X number of files, deploy again and the message will be updated to indicate it is only deploying x files.
However, I'm not sure what it uses to compute the diff. Maybe it compares it to the files currently in your staging bucket and if the files in the staging bucket have been deleted (they have a default life span of 15 days) it will deploy all the files again (but as I said, I'm not sure of this)
I am very, very new to Google App Engine, but I need to administer a WebApp2 (so, Python) -based website that uses it. Specifically I need to filter a queryset and delete certain model instances.
Building the site locally is fine. Locally I can get at the models by hitting
http://localhost:8000/console
in my browser. This pulls up the "interactive console", and in there I can put some code like
from application.models.user import User
and it will work. From there I can create / delete User objects in the Datastore, so this local interactive console seems to have ORM-like functionality. (I'm coming from a Django background, so that's what it reminds me of).
However I don't seem to have this option on the live website. I was hoping to find it at
https://console.cloud.google.com/home/dashboard?project=<my project>
And I thought I had found it when I found the control to "activate google cloud shell". This brings up a command line on the web server, but the website's codebase doesn't seem to exist here, so launching the Python cli and trying to import the applications models like I can do locally doesn't work. And even if I could, I doubt it would be a Django-like ORM the way it is on my local build.
Am I thinking about this in the wrong way? How do you create / filter / delete / etc. Datastore objects via the backend in a GAE / WebApp2 website? Is the "Google cloud shell" even part of the answer?
To get access to your app code in the cloud shell one option would be to create in the shell a local copy of your app repository. For an example (addressing a different question, true) you can peek at Google Cloud: How to deploy mirrored Repository. But I'm not 100% certain if that will automatically give you access to your app's datastore. Worth a try IMHO.
Another option is to hook the desired operations as handler actions inside your app itself and execute them from there. Eventually hidden/protected/restricted via authentication, for example for admin users only. This is what I use for one-time datastore migrations that I need from time to time when I make changes to my entity models.
Finally, but not really a programatic access - you could use the Datastore page in the developer console to manually find, read and modify your entities, see Managing Datastore from the Console.
Use the remote_api_shell. You run this locally where your application code lives. Then you can import your models, and perform the same queries etc, and add modify/delete entities. I use this frequently for a range of tasks. Updating more than 100K records can become slow using this method.

I have an app on GAE in which I'm using the Google Directory API for retrieving organization units and users. I am wondering if this API or any other have the option to update the extension force install list. Currently it's done by copying links and IDs to the Google Admin Console, but I am looking for a solution (if one even exists) to have this feature implemented directly in my application.
Thanks!
I believe there is an undocumented Google API available to create and manage Google Cloud Console (and App Engine) projects on behalf of third party users.
Does anyone know how to use it?
I think older versions of the Google Eclipse Plugin obtained an OAuth2 token in the (undocumented) scope https://www.googleapis.com/auth/appengine.admin, and this allowed it to generate a Cloud Console project on your behalf. The latest version doesn't seem to do this. App Engine's own appcfg.py also uses this scope, but doesn't seem to do much more than deploy the code - I'm looking to change core settings for the project, such as Name, Redirect URLs, and Web Origins.
Any information would be appreciated.
I maintain a WordPress plugin providing secure Google Apps Login for end users, and currently have to give detailed instructions to admins for creating a new Cloud Console project manually, and entering settings such as Redirect URL. Ideally, I would create a simple on-line service to do all of this for them.
Thank you!
It is possible to programmatically create a new Developer Console project on behalf of a Google Account (yes, you read that right). You do so in a very roundabout way:
Request the https://www.googleapis.com/auth/drive.scripts scope from the user (standard OAuth 2.0 flow).
Use the Drive API's drive.insert method to create a new file with a mimetype of application/vnd.google-apps.script.
Somehow try to get the project ID, maybe by uploading some Apps Script code? This is the part that I was never able to figure out.
A little known fact is that every Google Apps Script project has a hidden Developer Console project associated with it. This project is not shown in the list of projects, but it does exist. It is created automatically when the user starts a new Apps Script project, and the drive.insert method is enough to cause this to happen.
How do you get to the hidden project? Well, the only way I know of is to open the Apps Script project from the Drive website, open the "Resources > Advanced Google Services" dialog, and click the link to the Developer Console. You'll find the project ID in the URL.
Aside from not being shown in your list of projects and not being able to use App Engine, this is a normal Developer Console project. You can add additional OAuth client credentials, service accounts, Compute Engine instances, etc. And of course once you have a project ID, all of the various management APIs will work: creating new virtual machines, making use of a service account's impersonation ability, etc.
I recall seeing an option on the google app engine admin page that would allow me to duplicate/copy a deployment to a different appid. Was I imagining this? I do have a copy of all the files needed for deployment but I do not currently have access to a computer with admin privileges in order to install the GAE SDK.
Not relevant to this question, but FYI I need to do this simply because there is a major bug that's preventing me from logging in to a particular part of the admin interface and google tech support has failed to resolve the issue, so I'm just trying a workaround.
Copy old settings to new app via the admin console admin>application settings>Duplicate Application Settings. (you'll choose new appid here too)
Then upload a version of your code to the new appId (so you'll need gae sdk or use online sdk devtable).
Then go to datastore admin in the old app, select all the entities and choose "copy to another app" You'll need datastore admin to be enabled on the old app (and new app I think).
