read csv-data and put it in an array

[sdetweil]

@Perlchamp there is NOT an this. updateDom() in the getDom() section…

still doesn’t change the result… there are no birthdays found that match 02/05

[Perlchamp]

the columns are:
birth, name

and is called “birthdays.csv”

the data are:
23.01.1987,Thomas Roth

[sdetweil]

@Perlchamp so there are no birthdays for today… we are ONLY selecting for TODAY. not every day

[Perlchamp]

why for TODAY ? and not for current MONTH ?
getDon:

	getDom: function() {
		var self = this;
		var wrapper = document.createElement("div");
		
		// tell MM to call and get our content
Log.log("LOOK >>>>>>" + JSON.stringify(this.active_birthdays))    // add this line
			self.updateDom();                          // before this line in the notification code..

		for(var birthday of Object.keys(this.active_birthdays)) {
			for(var name of this.active_birthdays[birthday]) {
				var m = document.createElement("div");
				Log.log("BIRTHDAY >> " + birthday);
				Log.log("NAME >> " + name);
				m.innerText = birthday + " " + name;
				wrapper.appendChild(m);
			}
		}

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

[sdetweil]

@Perlchamp said in read csv-data and put it in an array:

  // tell MM to call and get our content

Log.log(“LOOK >>>>>>” + JSON.stringify(this.active_birthdays)) // add this line
self.updateDom();

not that way

			      // save the persons name and age on the list
			      self.active_birthdays[birth_date].push({'name':birthday.name, 'age': now.diff(moment(birthday.birth,'DD.MM.YYYY'), 'years') })			     
			   }
			}
     
			// tell MM to call and get our content
Log.log(JSON.stringify(this.active_birthdays))		  // add this line	
			self.updateDom();                 // before this line        
		}     		

sorry, didn’t see the ‘month’.

still doesn’t matter, that birthday is for january, so nothing to show for may

change this compare to do only month

		  // if the date is the same or later, don't use time of day
		   if(birth_date_moment.startOf('day').isSameOrAfter(now.startOf('day')) &&
		   	  birth_date_moment.startOf('day').isSameOrBefore(birthday_time_window.startOf('day'))

hint, google get month from moment

i got this:

[2020-05-02 18:10:50.465] [LOG]    {} (/home/dirk/MagicMirror/modules/MMM-Logging/node_helper.js:34 Class.socketNotificationReceived)

for each entry. i have 5 birthdays in may …

[sdetweil]

@Perlchamp look in the console log, MMM-Logging is redirecting everything there
my mmm-logging config

		{
            module: 'MMM-Logging',
            disabled: false,
            config: {
                // Module functions out of the box with nothing set here.
                // See below for configurable options.
                echoLocal: true, 
                echoRemote: true,
                overwriteBrowserMethods: true,
                format: "{{message}} ({{folder}}/{{file}}:{{line}} {{method}})",
            }
        },

i could send you the three files (node_helper.js, MMM-Perlchamp.js, birthdays.csv) via email ?
