问题 According to Googles Documentation, null values have no sort order. Is there any way to configure this behavior. For instance, if I am sorting an integer property in ascending order, can I configure the datastore to return null values last or first? 回答1: Your best bet may be to save the property as a blank "" string for each entity that has a null value for that property. Be sure to run put() on each entity that you alter. employees = Employee.all().fetch(50) for employee in employees: if

问题 I'm writing an adroid app that used to upload a chosen image to the users' google drive. I have cloned the code from git to another machine and then the image won't upload any more. I get a com.google.android.gms.auth.GoogleAuthException: Unknown exception. but it's caught here: } catch (IOException e) { e.printStackTrace(); } if(fileContent.length() > 5 * 1024 * 1024) { // Resumable Uploads when the file size exceeds a file size of 5 MB. // check link : // 1) https://code.google.com/p/google

问题 I have a wordpress site running on Google App Engine flex. I'm trying to use the php mail() function for a simple contact form. I have a block like so: if ( mail( $to, $subject, $message, $headers ) ) { //stuff } else { error_reporting(-1); ini_set('display_errors', 'On'); set_error_handler("var_dump"); var_dump(error_get_last()); echo '<pre>'; print_r (error_get_last()); echo '</pre>'; } I've tried using different $from emails with no luck. I get a NULL error message displayed in response.

问题 I have billing enabled on my project, and have even issued a $10 payment just to test out the process (it works). But I am unable to change my daily budget on the google app engine dashboard. I go to "Billing Status" section. I am entering the new daily budget and I hit the "submit" button. I am getting the not very informative error: "There was an error processing the request". So I'm stuck without being able to update my budget, and my quota has exceeded for instance hours. My users are

问题 Is there any way to run the compiler on an App Engine application written in Go without continue to serve the application with the development server and instead get an exit code? Because I want to add a check in my automated tests in Travis that the application actually compiles. To clarify: I have access to the App Engine SDK / Development Server in Travis, but I dont want to run goapp serve since it never exits. 回答1: Without actually implementing test, your solution looks pretty hacky. Why

问题 My reading is limited as of yet, but so far here are some key points I have identified for using the GAE Datastore: It is not a relational database. Data duplication occurs by default across storage space. You cannot 'join' tables at the datastore level. Optimized for reads with less frequent writes. These lead me to the following data model for a Blog System: Blogs have a relatively known set of 'columns': id, date, author, content, rating, tags. The Datastore allows for additional columns

问题 Few days ago I upgraded my app engine server to work with secure HTTP requests only (HTTPS). (by adding 'secure: always' line in the app.yaml file). Everything worked fine, I do manage to get response from my app engine server with my app (running on android 4.1.2), but today I found out that on 4.4.2 devices, I get the following error: 06-04 20:11:29.501: W/System.err(21158): javax.net.ssl.SSLPeerUnverifiedException: No peer certificate 06-04 20:11:29.504: W/System.err(21158): at com.android

问题 I'm developing a directory app on app-engine (python) and I've run into trouble with too many write ops. The first issue is that I have a .NET script that goes through an excel file and posts the data to a page in my app. When I ran it, it got through around 700 records and I had already used 75% of my write ops quota. The same thing happened when I wrote a script to update all of my models to have a search field for each property. I went from 75% of the quota filled to 96% in around 20
