read csv-data and put it in an array

[Perlchamp]

the same see picture i did send to you. it’s line 122 => stop => refresh => and than like posted before
no does nothing … ok never mind. coming from germany it’s now 06:00 in the morning did’t sleep …

[sdetweil]

@Perlchamp tomorrow, very close

[Perlchamp]

don’t worry about me and sleep well.

[sdetweil]

@Perlchamp thx…

in debugging

put a stop on the self.updateDom() in the notiification code.
no place else

hit refresh

when it stops there,
scroll down to getdom and add a stop on the 1st for loop line

hit run arrow,
should stop in getdom now, with data

[sdetweil]

@perl here is the updated perlchamp.js, shows date, persons name and age (no formatting)

this is the birthdays.csv I was using
the column names are the field names in the jsonobj

birth, name
12.07.1952, Sam
11.09.1944, Peg
02.05.1939, Frank 
09.04.1953, June
09.04.1953, Jane
30.12.1955, Joan
02.05.1939, Sue
05.05.1955, mary

hi sam :-)
see my module-file. why i don’t get values for the Log.log(); statements ?

	// this is the major worker of the module, it provides the displayable content for this module
	getDom: function() {
		var self = this;
		var wrapper = document.createElement("div");
		Log.log("this.active_birthdays >>>>> ", this.active_birthdays);

		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;
	}

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

  for(var birthday of Object.keys(this.active_birthdays)) {
  	for(var name of this.active_birthdays[birthday]) {

that means one of those two for loops didn’t execute, as the list is empty

do this

 			// tell MM to call and get our content
Log.log(JSON.stringify(this.active_birthdays))    // add this line
			self.updateDom();                          // before this line in the notification code..

[Perlchamp]

and where i have to place it ?

[sdetweil]

@Perlchamp see my updated post above

[Perlchamp]

i get this for each entry (here i only posted one of them):

[2020-05-02 17:50:36.803] [LOG]    LOOK >>>>>>{} (/home/dirk/MagicMirror/modules/MMM-Logging/node_helper.js:34 Class.socketNotificationReceived)

empty: {}

[sdetweil]

@Perlchamp ok, so the data collection didn’t work…

so I would step thru that code

what is the 1st row of your csv file? the column headers

[Perlchamp]

before you do this. stop. i make an error. the code you posted is not in the notification section. it’s in the getDom section … so i placed it there. was this wrong ?

[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

[Perlchamp]

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}})",
            }
        },

[Perlchamp]

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