[JavaScript] Subtract month from date

//Input String yyyymmdd
var date_string = '20200101';

//Create date object
var oDate = new Date(date_string.substr(0, 4), date_string.substr(4, 2), date_string.substr(6, 2));  

oDate.setMonth(oDate.getMonth() - 1); 

var year = oDate.getFullYear().toString()
var month = oDate.getMonth().toString()
var day = oDate.getDay().toString()

//Add leading zero's
if (month.length === 1 ) {
	month = '0' + month;
}
if (day.length === 1 ) {
	day = '0' + day;
}

//Return string: 20191201
var sDate =  year + month + day;

[WordPress] 4 levels of caching

Good overview on: https://www.smarthomebeginner.com/wordpress-on-docker-traefik/#3_WordPress_Caching

Browser Caching: This is what tells the visitors browser to cache the files locally to speed up future site/page visits. We will set this up using Nginx. On Apache, this is accomplished using .htaccess files.

Server Caching: This caches static versions of pages (Page cache). We are going to accomplish this using Nginx FastCGI cache.

Frontend Caching: This means caching WordPress PHP files so they don’t have to be re-compiled for every visit. We are going to set this up using PHP OpCache.

Database Caching: This optimizes database queries by storing them in the RAM for faster delivery. We are going to use Redis for this.

[Nextcloud] Docker update v19 to v20 exception

Just did the Nextcloud Docker update version 19.0 to 20.0. I followed their guide on Github and updated my docker-compose file.

 nextcloud-app:
    image: nextcloud:20.0
    restart: unless-stopped
    volumes:
      - /opt/containers/nextcloud/app:/var/www/html
    depends_on:
      - nextcloud-db
      - nextcloud-redis
    environment:
        REDIS_HOST: nextcloud-redis
        REDIS_HOST_PASSWORD: XXXXXXX
    networks:
      proxy:
        ipv4_address: 172.1X.X.X

Followed by:

$ docker-compose -f /opt/containers/nextcloud/docker-compose.yml pull
$ docker-compose -f /opt/containers/nextcloud/docker-compose.yml up -d

After 10 minutes my Nextcloud was still in maintenance mode, so I checked the logs.

$ docker logs nextcloud-app_1

Seems like the news app updating process threw an exception. After searching for a minute I found this thread, where someone got the same error and just manually disabled the maintenace mode. So I did the same:

$ docker exec --user www-data nextcloud-app_1 php /var/www/html/occ maintenance:mode --off
Nextcloud or one of the apps require upgrade - only a limited number of commands are available
You may use your browser or the occ upgrade command to do the upgrade
Maintenance mode disabled

Went back to the WebGui, logged in and he asked me to update the news app. Now the update finished without problems.

[SAPUI5] MyInbox: Integration of Detail View – EmbedIntoDetail

https://launchpad.support.sap.com/#/notes/2305401 (App to App Navigation CookBook.pdf)

https://blogs.sap.com/2020/07/31/fiori-my-inbox-integration-of-custom-detail-page/

Target:

Go to /n/ui2/fpld_cust and define a second target for your App, i.e. approve.

The approve target needs the “emdedIntoDetails” parameter:

SWFVISU:

Add the new target for your WF Task. Here you have access to all attributes of your Workitem-Container. Pass all your mandatory fields you’ve defined in your oData Entity.

Some examples: https://blogs.sap.com/2016/05/31/my-inbox-open-task-swfvisu-configuration/

If your missing some parameters, just add them in your Workitem Task and pass the values directly into it right from your Workflow Container. This looks much better.

Manifest:

Add a route to navigate via Inbox. The pattern has to match your inbox url.

			"routes": [
				{
					"pattern": "",
					"name": "master",
					"target": "master"
				},
				{
					"pattern": "DataSet/{Pernr},{Datum},{Infty}",
					"name": "object",
					"target": [
						"master",
						"object"
					]
				},
				{
					"pattern": "detail/LOCAL_INBOX/{wfInstanceId}/{taskPath}",
					"name": "wfobject",
					"target": "object"
				}

Detail.Controller:

	onInit: function () {
			// Model used to manipulate control states. The chosen values make sure,
			// detail page is busy indication immediately so there is no break in
			// between the busy indication for loading the view's meta data
			var oViewModel = new JSONModel({
				busy: false,
				delay: 0
			});

			this.getRouter().getRoute("object").attachPatternMatched(this._onObjectMatched, this);

			//My Inbox Integration
			this.getRouter().getRoute("wfobject").attachPatternMatched(this._onWFObjectMatched, this);

			this.setModel(oViewModel, "detailView");

			this.getOwnerComponent().getModel().metadataLoaded().then(this._onMetadataLoaded.bind(this));

		},


		_onWFObjectMatched: function (oEvent) {
			this.getModel("appView").setProperty("/layout", "MidColumnFullScreen");
			var compData = this.getOwnerComponent().getComponentData();

			if (compData && compData.startupParameters && compData.startupParameters.PERNR && Array.isArray(compData.startupParameters.PERNR) &&
				compData.startupParameters.PERNR[0]) {

				var sPernr = compData.startupParameters.PERNR[0];
				var sDatum = compData.startupParameters.DATUM[0];
				var sInfty = compData.startupParameters.INFTY[0];

				this.byId("detailPage").addStyleClass("myInboxPage");

				this.getModel().metadataLoaded().then(function () {
					var sObjectPath = this.getModel().createKey("/DataSet", {
						Pernr: sPernr,
						Datum: sDatum,
                                          Infty: sInfty
					});
					this._bindView(sObjectPath);

				}.bind(this));
