Android Mobile Backend Starter fail with 404 not found… some times

由 流过昼夜 提交于 2019-11-27 02:50:45
问题 Last afternoon I created a project and deployed the mobile backend started. I edited the client code and sucessfully did some data insertion. Some time (hours) after, I changed the cliend code again and the insertion failed with the error: com.google.api.client.googleapis.json.GoogleJsonResponseException: 404 Not Found As I didn't did any substantial change in the code I concluded that the error was on the app engine side so I redeployed the project and that solved the problem. The insertions

How to add / remove columns in Woocommerce admin product list

由 北慕城南 提交于 2019-11-27 01:25:21
问题 I want to customize the columns in Woocommerce admin area when viewing the product list. Specifically, I want to remove some columns, and add several custom field columns. I tried many solutions listed online, and I can remove columns and add new ones like this: add_filter( 'manage_edit-product_columns', 'show_product_order',15 ); function show_product_order($columns){ //remove column unset( $columns['tags'] ); //add column $columns['offercode'] = __( 'Offer Code'); return $columns; } But how

Simple PHP editor of text files

由 旧街凉风 提交于 2019-11-27 01:08:17
问题 I have developed a site for a client and he wants to be able to edit a small part of the main page in a backend type of solution. So as a solution, I want to add a very basic editor (domain.com/backend/editor.php) that when you visit it, it will have a textfield with the code and a save button. The code that it will edit will be set to a TXT file. I would presume that such thing would be easy to code in PHP but google didn't assist me this time so I am hoping that there might be someone here

How to switch Backend with Keras (from TensorFlow to Theano)

由 旧时模样 提交于 2019-11-27 00:26:35
问题 I tried to switch Backend with Keras (from TensorFlow to Theano) but did not manage. I followed the temps described here but it doesn't work. I created a keras.json in the keras' directory (as it did not exist) but it doesn't change anything when I import it from Python. 回答1: Create a .keras (note the . in front) folder in you home directory and put the keras.json file there. For example, /home/DaniPaniz/.keras/keras.json (or ~/.keras/keras.json in short) if you are on a UNIX like system

Backend administration in Ruby on Rails

由 烂漫一生 提交于 2019-11-26 22:29:18
问题 I'd like to build a real quick and dirty administrative backend for a Ruby on Rails application I have been attached to at the last minute. I've looked at activescaffold and streamlined and think they are both very attractive and they should be simple to get running, but I don't quite understand how to set up either one as a backend administration page. They seem designed to work like standard Ruby on Rails generators/scaffolds for creating visible front ends with model-view-controller-table

How can I take a screenshot/image of a website using Python?

由 流过昼夜 提交于 2019-11-26 21:19:52
What I want to achieve is to get a website screenshot from any website in python. Env: Linux On the Mac, there's webkit2png and on Linux+KDE, you can use khtml2png . I've tried the former and it works quite well, and heard of the latter being put to use. I recently came across QtWebKit which claims to be cross platform (Qt rolled WebKit into their library, I guess). But I've never tried it, so I can't tell you much more. The QtWebKit links shows how to access from Python. You should be able to at least use subprocess to do the same with the others. Here is a simple solution using webkit: http:

How to handle XML services in AngularJS?

由 折月煮酒 提交于 2019-11-26 18:47:13
My company has thousands of existing xml web services and is starting to adopt AngularJs for new projects. The tutorial over at http://angularjs.org/ uses json services exclusively. It looks like they make a service call in the controller, parse the resulting JSON, and pass the resulting object directly to the view. What do I do with XML? I see four options: Parse it and pass the DOM object directly to the UI(view). Put a JSON wrapper around my XML services on the server side. convert the DOM object to JSON with some library on the client side and convert it back when I make the post/put

Do not use System.out.println in server side code

由 江枫思渺然 提交于 2019-11-26 18:31:35
I heard that using System.out.println for logging purposes is a very bad practice and this may force the server to fail. I don't use this approach but I am very interested in knowing why System.out.println could make so trash things when used in backend code. Lars System.out.println is an IO-operation and therefor is time consuming. The Problem with using it in your code is, that your program will wait until the println has finished. This may not be a problem with small sites but as soon as you get load or many iterations, you'll feel the pain. The better approach is to use a logging framework

Rails: store translations in database

由 我是研究僧i 提交于 2019-11-26 15:55:37
问题 I was searching for a plugin/gem solution to extend the native rails i18n for storing my translations into my database. Maybe I used the wrong search terms, but all I found was the information, that changing the backend IS actually possible and this blog entry which descripes how to write my own backend. It's hard to imagine, that all those rails apps out there having their translations stored in yml-files or every developer wrote own backends! Do you know working solutions for this? Storing
