Okay. And yes it does return the data as output I believe

beejay22

Did you try it with the pyscript? Or are you talking about it the core module, node_helper and config?

And okay

beejay22

Sorry I copied the wrong node_helper.js file in my last post. This is how it looks like now:

//node_helper.js
const spawn = require("child_process").spawn
var NodeHelper = require("node_helper")

module.exports = NodeHelper.create({
  socketNotificationReceived: function(notification, payload) {
    switch(notification) {
      case "GIVE_ME_DATA":
        console.log("received notification")
        this.job()
        break
    }
  },
  job: function() {
    var process = spawn("python3", ["/home/pi/Desktop/realTester.py"])
    process.stdout.on("data", (data)=>{
      console.log(data.toString())    
      this.sendSocketNotification("HERE_IS_DATA", data.toString()) 
    })
  }
})

I was trying to test if I can at least print something to magic mirror without a pyscript… node_helper looks like this:

//node_helper.js
const spawn = require("child_process").spawn
var NodeHelper = require("node_helper")

module.exports = NodeHelper.create({
  socketNotificationReceived: function(notification, payload) {
    switch(notification) {
      case "GIVE_ME_DATA":
        console.log("received notification")
        this.job()
        break
    }
  },
  job: function() {
    var process = spawn("python3", ["/home/pi/Desktop/test.py"])
    process.stdout.on("data", (data)=>{
      data= "Hello World";
      console.log(data.toString())   
      this.sendSocketNotification("HERE_IS_DATA", data.toString())  
    })
  }
})

Hello World appears on MagicMirror but the test file that’s provided in the path (the test file just has: print(“this works”) does not so I’m not sure why I need to provide var process spawn if Hello World prints by itself… Anyways, I’m aware that there’s other ways to execute the child process however I’m not familiar with it. Please correct me if I’m wrong but can exec work in this situation as well? (pyscipt just prints out the latest titles when magic mirror restarts). I’m trying anything and everything at this point

And I added the default and start function to my core module although I don’t think I have to use it. This is how it looks like now:

/// MMM-Whitehouse.js - Core Module

Module.register("MMM-Whitehouse", {
  defaults: {},
  start: function () {},
  getDom: function() {
    var e = document.createElement("div")
    e.id = "DISPLAY"
    return e
  },
  notificationReceived: function(notification, payload, sender) {
    switch(notification) {
      case "DOM_OBJECTS_CREATED":
        var timer = setInterval(()=>{
          this.sendSocketNotification("GIVE_ME_DATA")
        }, 1000)
        break
    }
  },
  socketNotificationReceived: function(notification, payload) {
    switch(notification) {
      case "HERE_IS_DATA":
        var e = document.getElementById("DISPLAY")
        e.innerHTML = payload
        break
    }
  },
})

Tried this (all I changed was “python” to “python3”):

const spawn = require("child_process").spawn
var NodeHelper = require("node_helper")

module.exports = NodeHelper.create({
  socketNotificationReceived: function(notification, payload) {
    switch(notification) {
      case "GIVE_ME_DATA":
        this.job()
        break
    }
  },
  job: function() {
    var process = spawn("python3", ["/home/pi/Desktop/realTester.py"])
    process.stdout.on("data", (data)=>{
      console.log(data)
      var result = String.fromCharCode.apply(null, new Uint16Array((data)))
      this.sendSocketNotification("HERE_IS_DATA", data)
    })
  }
})

And also changed pyscript to this (just added python3 to the shebang):

#!/usr/bin/python3
from bs4 import BeautifulSoup                                             
import requests                                                           

url=requests.get("https://www.whitehouse.gov/presidential-actions/")      
src=url.content                                                           
soup = BeautifulSoup(src, 'lxml')
for h2_tag in soup.findAll('h2'):
    a_tag = h2_tag.find('a')
    print(a_tag.string)

Also tested “python” again (not python3) in my node_helper along with the updated shebang as shown above

If custom.css file doesn’t matter I wonder why it’s giving this error… Have no clue what’s going on now lol

beejay22

I didn’t add the $ to the command, I just said that in my post for clarity lol. I typed just this in the command line:
chmod +x /home/pi/Desktop/realTester.py

And yes I can run my script in the terminal with “python3 /home/pi/Desktop/realTester.py” but not with “/home/pi/Desktop/realTester.py” because the module I’m using in my script includes bs4 which is available with python3 I believe so I have to say python3

I also tried ‘touch ~/MagicMirror/css/custom.css’, still showing same error log

beejay22

Hmmm I did this in the terminal:
$ chmod +x /home/pi/Desktop/realTester.py

Nothing changed… still the same error log message… I think there’s something wrong with my custom’s css file since it says it’s not loading… in my css folder there’s only a main.css file there

beejay22

Okay so now my pycript looks like this:

#!/usr/bin/python
from bs4 import BeautifulSoup                                             
import requests                                                           

url=requests.get("https://www.whitehouse.gov/presidential-actions/")      
src=url.content                                                           
soup = BeautifulSoup(src, 'lxml')
for h2_tag in soup.findAll('h2'):
    a_tag = h2_tag.find('a')
    print(a_tag.string)

If I’m my understanding correctly, adding this shebang line lets shell know that my src code is a script, the type of interpreter we want to use and the path of said interpreter…

Also am I suppose to execute chmod +x /home/pi/Desktop/realTester.py in shell? If so how and when… sorry I’m still trying to understand how exactly to do all of this

beejay22

Thanks for the insightful reply! I changed my node_helper to what you posted:

const spawn = require("child_process").spawn
var NodeHelper = require("node_helper")

module.exports = NodeHelper.create({
  socketNotificationReceived: function(notification, payload) {
    switch(notification) {
      case "GIVE_ME_DATA":
        console.log("received notification")
        this.job()
        break
    }
  },
  job: function(){
    var process = spawn("/home/pi/Desktop/realTester.py")
    process.stdout.on("data", (data)=>{
      console.log(data.toString())    
      this.sendSocketNotification("HERE_IS_DATA", data.toString())
    })
  }
})

However, when I changed it I got an error message in the terminal which hasn’t happened before. Error message in terminal:

[2020-08-23 22:36:26.161] [ERROR]  Error: spawn /home/pi/Desktop/testing.py EACCES

Still getting the same error log in the magic mirror using dev mode though… lastly this is my pyscript, realTester.py:

from bs4 import BeautifulSoup                                             
import requests                                                           

url=requests.get("https://www.whitehouse.gov/presidential-actions/")      
src=url.content                                                           
soup = BeautifulSoup(src, 'lxml')
for h2_tag in soup.findAll('h2'):
    a_tag = h2_tag.find('a')
    print(a_tag.string)

Hi. I’m very new to coding and I have a pyscript that simply prints out the latest titles from a website using BeautifulSoup. However, when I launch magic mirror it’s just a black screen. I deleted all other modules besides my own in the config file so that it’s just my module that runs. I’ve done ample research and can’t seem to figure out what’s going on (updated mm software, reinstalled dependencies in the css directory just in case it wasn’t installed correctly, checked to see node was up to date - v10.21.0, etc.). I’m starting to think it may be my pyscript but it runs correctly in the console (I can attach my pyscript if needed). I’m not sure what the problem is so I appreciate any and all help!
