Module to Display JSON data from a FILE

[sdetweil]

@mhr320 ok, I put a file in MagicMirror/modules
fribble.json

{
 "items":[ {"test":"foo","xyz":"test"}]
}

and used this URL

http://localhost:8090/modules/fribble.json

and got this

so the path works…

using this JsonTable module,
then config would be

{
  module: 'MMM-JsonTable',
  position: 'top_right',
  header: 'HouseDB Sevensegment',
  config: {
    url: 'http://localhost:8090/modules/fribble.json', // Required
    arrayName: 'items' // Optional
  }
}

and got this

[sdetweil]

@mhr320 JsonTable expects a different format…

I didn’t try the others… some are more flexible, some not

i did not try with your data

[mhr320]

@sdetweil Ok, I’ll get back to trying it, I must have messed up an entry somewhere.

[mhr320]

@sdetweil So the path does indeed work, what was preventing me from seeing the data was the arrayName in the config. That does have to be set regardless of it saying it is optional.

So that problem is solved, do you think I can solve the sharing of screen time for each of the three array’s in the json file via css or will that take some javascript? That was really what was important because the information is for my three kids and they each attend a different school.

I really appreciate your help and patience.

[sdetweil]

@mhr320 yes , the arrayName has to be set. had the same problem

sharing

well that gets a bit more complicated . this module doesnt support multiple instances w different urls.

if it did, then you could make three files or use different arrayName settings

then you could also use mmm-pages and display 1 each per child

i can add that support later tonight, pretty easy but. have grandson duty for a while

[mhr320]

Enjoy the grandson, i am of no importance! Thank you!

@mhr320 rename the MMM-JsonTable folder out of the way
and

cd ~/MagicMirror/modules
git clone https://github.com/sdetweil/MMM-JsonTable.git
cd MMM-JsonTable
git checkout multiinstance
npm install

then in config.js
you can have multiple instances with the same url
and different arrayName (even the same,…)

then if you use MMM-Pages

   {
        module: "MMM-pages",
        config: {
            rotationTime: 1000 * 20,         // rotate every 20 seconds
            modules: [
                ["family"],                // page 1
                ["kid1 name"], // page 2
                ["kid2 name"], // page 3
                ["kid3 name"], // page 4
            ],
            fixed: [                         // modules that are always shown
                       "fixed"
            ],
        }
    },

then on each other module
add, after the module: line
classes:“xxxx”
xxxx one of the names above, family, kid1, kid2, kid3
for modules on every page use classes:“fixed”

above config has 20 seconds on each page… you can change that

Absolutely Brilliant! Since I downloaded the multi-instance version of MMM-JsonTable from you, I assume it will not be available when updating. I will diff the original from yours and learn what you did to make it multi-instance and send that off to the author of MMM-JsonTable as a feature request. I really appreciate your help. It was nice to have a pleasant experience in a forum for a change, does not always go that way.

@mhr320 I submitted pull request

I am glad to hear that it worked out, and sad to hear the other.
as the moderator here, I am interested in feedback on how to make it better most of the time…

[mhr320]

@sdetweil Hard to say how to improve things from our interaction. 5/5 Stars. I am new-ish to actively using this forum and wanted to give you props for your efforts, not sure if I did through any formal process, I tried to show the answer as the solution and attempted to upvote, but not sure if I did. But if you are the mod and jumped in to help me, that is a great way to make the forum better. Take care and enjoy the grandchild!

[sdetweil]

@mhr320 no… you said in " a " forum for a change, does not always go that way.

I wanted to know what that was… was that HERE?

we try hard to make sure everyone gets supported in some way

upvote/downvote are restricted to user that have reputation 2 or above (means someone liked/upvoted your contribution twice)
this was we know reputation is not tainted with transient (mostly down) voters…

same as having all posts reviewed before live posting, til you rep is 2 or above.

[mhr320]

@sdetweil Oh, in “a forum” was relative to another forum, this is the first time, in a long time, i’ve used this forum. HERE has been great every time so far, sorry for the misunderstanding.

[sdetweil]

@mhr320 the author accepted my change request

so you could go to the old folder (if you just renamed it) and git pull to get the update
then swap(rename) the folders and retry with his code again
and then delete mine

[mhr320]

Whoa, that was fast on both of your parts. I went to his github page and saw several old open “issues” i figured he’d be asleep on the project, but wow! It worked, great job sir! I really look forward to my next issue.

@timdows you should add a git pre-commit hook to run prettier for whoever…

here is mine
.pre-commit

#!/bin/sh
FILES=$(git diff --cached --name-only --diff-filter=ACMR "*.js" "*.jsx *.json" | sed 's| |\\ |g')
[ -z "$FILES" ] && exit 0

# Prettify all selected files
echo "$FILES" | xargs ./node_modules/.bin/prettier --write

# Add back the modified/prettified files to staging
echo "$FILES" | xargs git add

exit 0

and an npm postinstall script to copy to the git folder

#!/bin/bash
#echo copying git pre-commit hook 
cp .pre-commit .git/hooks

package.json

  "scripts": {
    "postinstall":"whatever you call it"
