Input list doesn't load

ivancaregnato · 2018-02-27T10:40:44.876Z

Hi Paul,

I run the latest version, 9.8.28 if I remember well.
Yes I’ve cleared my browser cache, tried changing it with another one and from another PC.
I’ve solved the issue with multigraph by clearing the cache few days ago but the input issue still remains.
The only thing I can see from that page is the spinning wheel over a blank page (excluding the header and the footer).

Can you provide more info? There are a number of questions asked in this thread.

TrystanLea:

Could you check the result from this URL which will attempt to access the underlying input list data:

http://emonpi.local/emoncms/input/list.json

TrystanLea:

If you run $ pecl info redis

TrystanLea:

Did you run the database update?,

TrystanLea:

Does http://emonpi.local/emoncms/input/getinputs.json, still return something useful? and http://emonpi.local/emoncms/input/list.json just a blank result?

TrystanLea:

Could you check if you see any errors in your browser’s web console?, usually accessible from developer tools (Ctrl-Shift-J on firefox).

is the issue exactly the same as when you had it before? I do not mean are the “input page not loading” symptoms the same, are the results of the tests the same?

input/list.json: no result at all, blank page

The error I get is exactly the same I had and fixed few months ago…unfortunately I don’t know when it happened again because I don’t check input page so often…I just needed to edit a value so few days ago I went there. Let me know if you need anything else

ivancaregnato · 2018-04-20T08:53:50.261Z

Hi guys, any hint?

Boye · 2018-04-22T15:09:05.771Z

Have you added the two lines as suggested in post 49: Input list doesn't load - #49 by Boye

Remember to put your emonPi in read/write mode before adding the lines…

best regards
Henrik

ivancaregnato · 2018-04-23T06:49:35.263Z

No I haven’t but I’ve just tried and it works, thank you man!

pb66 · 2018-04-23T09:11:36.931Z

Those 2 lines have been in emoncms since May 2017 (v9.8.6), if they were not there for you, you are not running the updated/latest version. If you believe you were, then you should check for local changes that may be blocking the previous updates, just as this edit will block future updates.

That was specifically why I asked

pb66:

What version emoncms are you running? when did you last update?

ivancaregnato · 2018-04-23T09:21:15.389Z

I’m actually (and I was) on 9.3.8, the fix on 9.8.6 worked correctly at that time for this issue…I sincerly don’t know what happened after that. I haven’t blocked anything on purpose and I haven’t manually edited anything before.

ivancaregnato · 2018-04-26T12:19:11.792Z

hi @pb66, I write this just to inform you that after an update (emonbase update) I’m facing this issue again…I suppose I need to edit that file to fix it…

pb66 · 2018-04-26T16:29:08.935Z

It looks like the previous fix has been removed again in a later commit.

I have submitted a PR for consideration, but it’s untested as I’m not able to recreate the issue. Perhaps you could test by manually adding a line as done previously, but in a different place as the code is different now.

See https://github.com/emoncms/emoncms/commit/5ca10931f577dad65beb188c2a5f9f2bb4…c74ce8 and OEM forum thread https://community.openenergymonitor.org/t/input-list-doesnt-load/3797/65?u=pb66.

Please let us know if it works, perhaps @TrystanLea can review the change.

If you just stumbled here from google like I did, and you JUST installed emoncms, if your emoncms database is a new database and no inputs or devices are yet configured. Then this will happen to you as well.

The solution is to Goto Admin, click the drop down arrow next to Full Update, and next click Update Database Only.

It will create the necessary tables in your new database.

How did you do the install? The last thing EmonScript does is run that exact command so the database should be there ready.

xekon · 2019-12-23T19:55:01.050Z

I seen that the official install method was to install it so that the user can issue sudo without password, didnt really like that so I followed this one:

github.com

emoncms/emoncms/blob/master/docs/SharedLinuxHostingInstall.md

# Shared Linux Hosting

Your shared hosting provider should already have a LAMP server installed. You may need to ask your hosting provider to enable mod_rewrite. It's unlikely that redis will be available (redis is used to improve performance through caching), but emoncms can be run without it.

To install emoncms on a shared server

1) Check with your hosting provider that mod_rewrite is enabled

2) Download the emoncms zip file from:

**You may want to install one of the other branches of emoncms here, perhaps to try out a new feature set not yet available in the master branch. See the branch list and descriptions on the [start page](https://github.com/emoncms/emoncms)**

[https://github.com/emoncms/emoncms/archive/stable.zip](https://github.com/emoncms/emoncms/archive/stable.zip)

Unzip to your shared server's public_html folder, rename the folder to emoncms.
i.e. You should end up with all the files in the directory public_html/emoncms/

3) Create a mysql database for your emoncms installation, note down its name, username and password.

4) In your shared hosting /home/username folder create a folder called emoncmsdata to hold your emoncms feed data.

This file has been truncated. show original

That guide is not a complete step by step but I know enough about Linux to make that install method work. I can write up a short guide later.

This is only for instances where you are using a ‘Shared Hosting’ environment i.e. not on your own machine/RPi etc.

I’m not surprised it doesn’t work.

What hardware are you using?

Not to mention that a “paswordless sudo” is easy to change to a “password required” sudo.
A small change to one line in /etc/sudoers is all that’s necessary.

borpin · 2019-12-24T07:56:24.576Z

Yes you could always change it back.

I will admit it is a bit of a hack but within a home network does not pose any real risk. If you use Raspbian, this is how the default user is setup, hence the change for other Debian distros.

If someone with more knowledge than me would like to suggest modifications to the scripts such that sudo is not needed on Debian (but still works with Raspbian) we’d be open to exploring that.

xekon · 2019-12-24T08:23:46.980Z

I have everything working good now I am using an Arduino Due. emoncms is running on a server with Ubuntu 18.04.

root · 2021-06-04T15:32:08.972Z

Apologies for resurrecting such an old thread but it looked like this is exactly the issue I’m facing.

I had the rpi eat an SD card so did a fresh re-install from emonSD-24Jul20.img on a new SD card and when trying to set up the inputs it just hangs at “Loading”. I thought maybe I’d done something stupid so since it wasn’t configured just rewrote the image but the same thing happened - the input list will not load.

Looking in the javascript console I see the following error:

    vue.min.js:6 ReferenceError: col_h is not defined
    at eval (eval at Ya (vue.min.js:1), <anonymous>:3:3920)
    at wn.vt [as _l] (vue.min.js:6)
    at eval (eval at Ya (vue.min.js:1), <anonymous>:3:2718)
    at wn.vt [as _l] (vue.min.js:6)
    at wn.eval (eval at Ya (vue.min.js:1), <anonymous>:3:80)
    at wn.e._render (vue.min.js:6)

    at fn.get (vue.min.js:6)
    at fn.run (vue.min.js:6)
    at un (vue.min.js:6)

I found if I had the console open I could catch the error and the rest would render but thought it worth flagging here regardless as this is a fresh install.
