Unable to display weather description

mochman

Yeah, it does look like the module gets back an array of weather data for each day. Have you tried putting some console.log() statements in your code to try and troubleshoot where the problem is. Like

this.desc = data.weather[0].description;
console.log("Description Var - " + this.desc); //See if anything is output

At least then you’d know if the variable is correct and your div statement isn’t working, or the variable isn’t getting set correctly.

@mochman Thanks for the great tip! Now I can see in the console whats happening in the background, and it’s really interesting.

I’ve put console.log in 3 places in the code:

in the start: function()

console.log("Description 1 - " + this.desc); //See if anything is output

in the getDom: function()

var description = document.createElement("div");
description .innerHTML = this.desc;
large.appendChild(description);
console.log("Description 2 - " + this.desc); //See if anything is output

and in the processWeather: function(data)

this.desc = data.weather[0].description;
console.log("Description 3 - " + this.desc); //See if anything is output

I also put a test line in the getDom function to see if it’s working:

var test = document.createElement("div");
test.innerHTML = "Lorem ipsum.." + this.desc + "..END";
large.appendChild(test);

And here you can see the results:

As you can see, only the third console.log has the value, and the first two has only “null”. The “null” is also in the test line Lorem ipsum…

Any idea whats wrong? I think I’m really close to the solution, but I just need some more help :)

@mochman Something happened :) After I submitted the post 2 minutes ago, I went back to the MagicMirror and…look :)

So I think after a few minutes, the processWeather: function() updated itself, and could display the correct value.
But still, do you think we can make it work so it will display the correct value at first run?

Well I’m glad it started mostly working. Sorry about the array of weather I was talking about earlier. I though you were using the weatherforecast module to get this info, not currentweather. The way you’re describing the issue, it sounds like the updateDOM() function is getting called before that value is set. Where in the processWeather() function did you put this.desc = data.weather[0].description;? is it before this section?

this.show(this.config.animationSpeed, {lockString:this.identifier});
this.loaded = true;
this.updateDom(this.config.animationSpeed);
this.sendNotification("CURRENTWEATHER_DATA", {data: data});

@mochman Ohhh you are sooo right!! I messed up the code, the declaration was after the updateDom function. I moved it before the function, and now it’s wooorkiiing!!! :)
Thank You Soooo much! I’m very happy now that it’s working like a charm :)

Glad to hear it.
