retranslate | Real simple translations for react | Internationalization library

This query update one column if UserName has only numbers.

I use an open-source server application running on Docker Compose. It has a few services, including PostgreSQL DB and Redis.

How can I best deploy this application to AWS in full IaC with Terraform?

ecs-cli now supports sending docker compose configs in Amazon ECS.

However, I do not think it could be integrated with the Terraform workflow (which is maybe not a big fuss). What I know for sure is that ecs-cli is not supported in CloudFormation, as per this issue, still open at this time. So I assume it cannot easily be added to Terraform either.

• Take your docker-compose.yml file, translate it to kubectl YAML.
• (Prepare to doing so every time the package upgrades).
• Deploy using Terraform's + EKS APIs (minimal example).

But that is not fully IaC yet. And you have to retranslate your config each time the docker-compose changes in the source repository. And it sounds like a lot of work.

• Write a Helm chart for the application.
• Run Terraform to start a cluster.
• Still run Terraform with a helm provider to install the application with Helm on the cluster.

I read Kompose can automagically translate a Docker Compose configuration to a k8s configuration, but they don't appear to be ported on AWS, not to talk about Terraform.

• Build a custom EC2 AMI with Packer.
• Using Terraform, set up the DB, Redis and all permissions / network / etc.
• Start an EC2 instance with the custom AMI.
• The AMI contains (customized) application code, especially the docker-compose.yml. And the Docker images.
• The AMI starts a Docker Compose systemctl service.

That would kind of hurt: long builds, difficult monitoring, no scaling.

• I mentioned I need full IaC. What I mean by it is:
  1. The written config (and it only) on master tells you what is deployed.
  2. The deploy will complete without my team having to run any other command. It basically works either on CI/CD or on single-push'n'go.
  3. Monitoring and alerting are easily configured in the IaC.
• I wish to replace some services with AWS components (namely, the PostgreSQL service by an RDS, and the Redis service with an ElastiCache).
• The application happens to be Apache Superset. However I am also wondering what is considered the best general approach to this Docker Compose problem.

I have a custom class where I need to save the new selected language and change the app language at the same time. An example based on the StackView sample project in QtCreator:

My goal is to retranslate a QObject subclass on the fly.

In QWidget it's really simple to catch QEvent::LanguageChange: we just override changeEvent. However, there is not such method in QObject and this is where I'm stuck.

How to catch QEvent::LanguageChange in QObject?

I have the following HTML code:

Lets suppose we add some TabButton using the qmljavascript, with the line tabBar.addItem and as argument tabButton.createObject.

Now what i want to do is if i change the language i want the text of the TabButton to change too.

How can this be done?

I know i can have on components (and i already have it working on a real app) a conection (that reacts to a signal) from a c++ class where we load the translations like this

This may seem like a dumb question, but i'm having lots of trouble to have internationalization working well in QT 5.12.

There are at least 2 things i would like to do:

• The possibility to save the language that was selected by the user and the next time the user runs the app its selected (but problably that would require at least a file to save that), or run the app in the native language of the SO.
• Having a dynamic translation working, by this i mean the language to be automatically changed while the application is running.

About the first point i know that to install the translation of the native language of the system something like Translator.load("qt_" + QLocale::system().name(),QLibraryInfo::location(QLibraryInfo::TranslationsPath)) can be used.

The second point, i've found a solution but it requires that i place a folder with the name translation(on this case) on the release/debug folder where i place the individual .qm files.

I'm going to provide a simple example of what i've found so far:

main.cpp

For instance if the header displayed "ColumnName" in English I have tried to change it to a new language by handling the language change event:

I'm running QT 5.10.1 on Windows, the app is only made in QML. I'm trying to use the new retranslate() to change language during runtime. The current code is working fine with texts that use the getEmptyString() appended to it. But the rest of the text within qsTr() does not. TranslationHandler.cpp is empty and I haven't cleaned up the includes.

So I'm able to set a language from the QML using the context property. Also I checked so the engine is the same instance. Any ideas why the retranslate function is not working?

Thanks for the help!
