read csv-data and put it in an array

Perlchamp · May 2, 2020, 12:27 AM

so, sam, everything is fixed :-)
but now i don’t know how to handle the receiving data. i only need a little entry … don’t know how to handle this object-element. actually nothing is displayed except the header i configured …

sdetweil · May 2, 2020, 12:39 AM

@Perlchamp cool, now you’ve collected the data… you should be able to see the results on the exit from the notification handler…

now to tell MM to come get the stuff to display…

thats the self.updateDom() call

hey MM, get my stuff

then MM will call getDom()

I have implemented the module too

getDom: function() {
		var wrapper = document.createElement("div");

		for(var birthday of Object.keys(this.active_birthdays)){
				for(var name of this.active_birthdays[birthday]){
					var m=document.createElement('div')
					m.innerText=birthday + ' '+ name
					wrapper.appendChild(m)
				}
		}

		// pass the created content back to MM to add to DOM.
		return wrapper;
	},

sdetweil · May 2, 2020, 12:46 AM

@Perlchamp one thing to watch out for, getDom() will be called immediately, long before you have any data,
but you MUST return something… so an empty div works… (this is where that 'Loading…" message would be presented

sdetweil · May 2, 2020, 1:13 AM

@Perlchamp ok, couple problems… in teh notification handler we write to active_birthdays,
but it is a variable local to this routine… so, when this routine ends, it goes awau

need to move its definition to the top


	defaults: {
		language: "de",
		dimmEntries: true   // true: dims entries and the associated 
							//       symbol when the date has expired.
							// false: delete entries and the associated 
							//        symbol when the date has expired.
	},
    active_birthdays : {},

then add ‘this.’ in front of it in the notification handler
(and remove the var activebirthdays)

now it is an instance variable (one per browser)

also, I spelled substring wrong (I had it subString, its substring )

gotta run to store, back in a little bit

in node_helper.js was nothing to be changed. maybe I put a few semicolons where none have to go?

sdetweil · May 2, 2020, 1:56 AM

sorry, forgot one thing i saw in node helper,… need to move everything in the start function to the socketNotification section… at start time the module is not up yet, so the message goes nowhere

socketNotificationReceived(notification, payload) {		
	var self = this		
		// if config message from module
		if (notification === "CONFIG") {
			// save payload config info
			this.config = payload;
			var self = this;
			console.log("Starting module helper: " + this.name);

			// convert the csv-file into a JSON-String
			const csvFilePath = this.path + '/birthdays.csv';
			csv()
			.fromFile(csvFilePath)
			.then((jsonObj)=>{      
				birthdaysArray = JSON.stringify(jsonObj);
				
				// for debugging only
				console.log("birthdaysArray: ", JSON.stringify(birthdaysArray));
				
				// send data to [modulname].js
				self.sendSocketNotification("have data", jsonObj);
			})	
		}
		else if(notification === "????2") {
		}
	},

also, by moving it here, all you have to do is fix the code, save and then refresh the page… don’t have to restart MM

start is now empty

	start() {
	
	},

ok, nothing changed and i don’t see any messages of “HAVEDATA” (changed it in both files to big letter without space). i only see the header “Geburtstage” … :-(
node_helper.js:

		console.log("Stopping module helper: " + this.name);
	},
*/
	// handle messages from our module// each notification indicates a different messages
	// payload is a data structure that is different per message.. up to you to design this
	socketNotificationReceived(notification, payload) {

no… it will do the thig every time a notifcation comes in, only want it when the module sends down a message (say it is alive)

in node_help you are sending this “HAVEDATA”
and in module you are looking for this if(notification === “HAVEDATE”){

add a var self = this to start of socketNotificationReceived() and getDom()
