Show calendar based on IP Address accessed

sdetweil

@Spinster yes, the two pieces together

ipaddress:“…”
at each cal url block… only does one ipaddress per url

@MMRIZE
Here is my config

	{
		module: "alert",
	},

	/*
	{
		module: "updatenotification",
		position: "top_bar"
	},*/
	{
		module: "clock",
		position: "top_left"
	},
	{
		module: "MMM-ModuleMonkeyPatch",
		config: {
			patches: [
				{
					module: "calendar",
					method: "socketNotificationReceived",
					patch: async function (original, args) {
						const [ notification, payload ] = args
						if (notification === "CALENDAR_EVENTS") {
							const calendarName = this.config.calendars.find((cal) => cal.url === payload?.url)?.name
							const r = await fetch('http://10.5.11.1:8080/modules/getip')
							const ip = JSON.parse(await r.text())?.[ 'address' ] ?? null
							console.log(ip)
							if (!this.config.clientMap?.[ ip ]?.includes(calendarName)) {
								return original(notification, { ...payload, events: [] })
							}
						}
						return original(notification, payload)
					}
				}
			]
		}
	},
	{
		module: "getip",
	},
	{
		module: "calendar",
		header: "Home Cal",
		position: "top_left",
		config: {
			clientMap: {
				"10.5.11.5": [ "cal1" ],
				"10.5.11.6": ["cal2"]
			},
			calendars: [
				{
					fetchInterval: 10 * 60 * 1000,
					symbol: "calendar-check",
					url: "https://homecals/xEzboFt7Kr3Yfiys?export",
					name: "cal1",

				}
			]
		}
	}

This is showing both 10.5.11.5 and 10.5.11.6 the same calendar. Though 10.5.11.6 should not have any calendar since it is not defined. Even I tried without an entry of 10.5.11.6 in calendar map but it still showing the calendar. What am I doing wrong. Please advice

@MMRIZE I even added the calendarmap, I hope you seen my config.js sent earlier

Sorry, i think I have not installed Monkey module, will install and check again

Spinster

@sdetweil

Should I use your earlier code and this? Please advise

sdetweil

@Spinster yes you need both

I am away from my system for another couple hours

will collapse to one post then

sdetweil

@Spinster ok, here is the final

in calendar.js

add these variables

		updateOnFetch: true,
		useIPAddress: false     // add config var
	},
	timerHandle:null,                 // add this
	ourIPAddress:null,              // add this 
	requiresVersion: "2.1.0",

change this

	// Override start method.
	start () {

to
this

	// Override start method.
	startup () {

add this code

			let ip_match = false;
			if(this.config.useIPAddress){
			 const client_ip_for_this_calendar = this.getCalendarProperty(calendar.url, "ipaddress", null)
			 if(this.ourIPAddress)
			 	  ip_match = client_ip_for_this_calendar.includes(this.ourIPAddress)
			}
			if(this.config.useIPAddress == false || ip_match==true)
			  this.addCalendar(calendar.url, calendar.auth, calendarConfig);   // old original   line

and add this routine somewhere

  notificationReceived(notification,payload){
  	if(notification === 'ALL_MODULES_STARTED'){
  		// if we are using ip address checking
  		if(this.config.useIPAddress){
  			// loop thru all the modules
  			let m = MM.getModules().withClass("getip");
  			if(m.length){
  				// if getip is configured and not disabled
  				if((m[0].disabled== undefined || (m[0].disabled != undefined && m[0].disabled == false)) ){
  					// start a timer to wait for getip to finish
  					this.timerHandle = setInterval(()=>{
  						// get its dom content
  						let client_ip = document.getElementById("getip_address")
  						// if we found id
  						if(client_ip !== null){
  							// stop the timer
  							clearInterval(this.timerHandle)
  							// save our IP address, only need to look it up once
  							this.ourIPAddress=client_ip.innerText
  							// call startup
  							this.startup()
  						}
  					}, 500)
  				}
  			}
  			// thru the loop, didn't start a timer, module not found
			  if(this.timerHandle === null){
					// didn't find getip
					// module not found, can't do this later either
					this.config.useIPAddress = false;
					this.startup()
				}
			}
  		// use default
  		else
  			this.startup()
  	} 
  	else if (notification === "FETCH_CALENDAR") {
			this.sendSocketNotification(notification, { url: payload.url, id: this.identifier+(this.ourIPAddress?'_'+this.ourIPAddress:'') });
		}
  },

and in the socketNotificationReceived routine
change this

	socketNotificationReceived (notification, payload) {
		if (notification === "FETCH_CALENDAR") {
			this.sendSocketNotification(notification, { url: payload.url, id: this.identifier });
		}

		if (this.identifier !== payload.id) {
			return;
		}

to this

	socketNotificationReceived (notification, payload) {

		if (this.identifier+(this.ourIPAddress?'_'+this.ourIPAddress:'') !== payload.id) {
			return;
		}

and in the addCalendar routine
change this

		id: this.identifier,

to this

		id: this.identifier+(this.ourIPAddress?'_'+this.ourIPAddress:''),

to use

add the getip module to config.js, anywhere
add property to calendar above the calendars list (but still inside the config:{}{ section)

useIPAddress:true,

in any cal url block you want to be sensitive to IP address add property

    ipaddress:"xxx yyy zzz",  // space separated list of client ipaddresses this calendar can be displayed on

andhow

After installing MonkeyPatch and adding the patch you have mentioned, I get the following error message when I run , npm run config:check
[2024-05-07 23:32:55.179] [INFO] Checking file… /home/vjkings/MagicMirror/config/config.js
[2024-05-07 23:32:55.222] [ERROR] Your configuration file contains syntax errors :(
[2024-05-07 23:32:55.223] [ERROR] Line 56 column 20: Parsing error: Unexpected token function

As per config.js, Line 56 is this

patch: async function (original, args) {

Whole section of patch as follows
patch: async function (original, args) {
const [ notification, payload ] = args
if (notification === “CALENDAR_EVENTS”) {
const calendarName = this.config.calendars.find((cal) => cal.url === payload?.url)?.name
const r = await fetch(‘http://192.168.1.4:8080/modules/getip’)
const ip = JSON.parse(await r.text())?.[ ‘address’ ] ?? null
if (!this.config.clientMap?.[ ip ]?.includes(calendarName)) {
return original(notification, { …payload, events: [] })
}
}
return original(notification, payload)
}

If I ignore the error and run the server, I don’t get any calendar and it just says Loading… in the mirror page
What is the reason for the error. Please advice

Wow, Clear, will try it and provide feedback please.

Hi,
I made all the changes you have mentioned, it is working!!!. Thank you so much for the efforts.
However, following are the observation,
When I add the config.js with useIPAddress: true (calendar.js has the entry of useIPAddress:false in its default), there is no effect, however in calendar.js if I set the useIPAddress: true, it is working, I don’t understand why the configuration settings are not taken.

I clearly added the useIPAddress: true before the calendars declared as part of the module configuration. Please advice how to fix this.

I also have doubt on when we override the start to startup, how the notificationreceived is called. What happens when there is no start in the module.

In fact this is the first time, I have added code without understanding of anything :).

Please help me with configuration settings (config.js) to get it effected than hardcoding it to calendar.js
