The rollback command can rollback a transaction on the server, but you are unlikely to need to use that unless an <code>update</code> of your app failed for some reason. You should be getting some feedback from appcfg.py that such an action is required. Is that what you want to do? If so, just open a command prompt and type <code>appcfg.py rollback</code>.

Otherwise, please let us know what you are trying to accomplish by performing a 'rollback'.

If your application myapp resides in <code>C:\Users\Nilesh\Documents\</code> then directory path should be <code>C:\Users\Nilesh\Documents\myapp</code>

If you installed Google App Engine Launcher in your system, then installation path should be something like this <code>C:\Program Files\Google\google_appengine</code>

<li>run the batch file by simply typing "rollback"
this local utility changes directory, runs the appcfg rollback EXE &amp; points it to my war directory.</li>

Even better would be to establish a common utility(bin) directory and add it to my path variable. That way I can run this utility from anywhere.

This has been answered many times, but I had issues getting it to work for me too. If you are running Java and are also having problems or if you have Google's 2 factor authentication setup and that is giving you problems, here are the steps I used to make it succeed:

1) Make sure you have the Google App Engine in your Path in Environment variables. 
IE: C:\Users\yourUserName\Desktop\Eclipse\plugins\com.google.appengine.eclipse.sdkbundle_1.9.18\appengine-java-sdk-1.9.18\bin

2) Open up a command window AS AN ADMINISTRATOR! Do not just type cmd and enter, you need to type cmd, right-click on it, and open as admin

3) First, CD to the folder that has the WAR file in it. In my case, that was:
cd "C:\Users\yourUserName\Documents\MyWorkspace\Project1"
This is the same folder that has the src, .settings, and war folders in it.

4) In the cmd window, type: "appcfg rollback war" and press enter.

5) It will ask for your google credentials. If you do not have 2 factor authentication setup, simply type them in and press enter and you will be set.

6) If you DO have 2 factor authentication setup, go to your google accounts page (Just google for 'google account') and it will be the first or second one.
Next, under the "Signing In" category, go to App passwords.
Next, go to the bottom and under the select app dropdown menu, choose other and type in anything (IE: GAE rollback)
It will give you a password (16 digit random numbers). 
Finally, type in your email address in the command window and then type/ paste in this new temporary 16 digit password into the password section.

7) Profit!

In my case, I had to use the --no_cookies, without it, I had no premissions to do the operation.

I don't know much about these coding things everyone is talking about here..but I found a simple way to update the application..

<ol>
<li>Select your application and click on "EDIT".</li>
<li>A wordpad file should open up with application details. </li>
<li>Below the application there is version:1 </li>
<li>Simply change the version to version:2 instead of 1 and click "Save".</li>
<li>So, instead of updating the same version..you are deploying a new version..</li>
<li>Click on "DEPLOY".</li>
<li>Check your application now!</li>
</ol>

I'm using Windows 7 and for the life of me I cannot figure out how to call the rollback function on appcfg.py. All I want to know is what to type into the command prompt so I can rollback my app.

Google App Engine: appcfg.py rollback

我使用的是Windows7，我一直不知道如何在appcfg.py上调用回滚函数。我只想知道在命令提示符中输入什么内容，以便回滚我的应用程序。
