Remote script modification - Hippolyte - 12.02.2018

Hi everyone,

A lot of questions lately Smile

but this one may be tricky.
We have to update a script on 300 LMs, please tell me there is a simple way to do this remotely … The script name is the same on every LM.
I know there is no API for this but maybe you have another technical solution in your head !
Thank you very much for your help.

You can create a custom .lp file that will handle this, to which you must pass name and script get/post variables. Like this: http://LM_IP/user/update.lp?name=test&script=log(event)
For better security you should add some extra password/variable check to this file.

Code:
<?

name = getvar('name')
scriptdata = getvar('script')

if name and scriptdata then
  item = script.get(name)
  
  if item then
    item.script = scriptdata

    db:update('scripting', { script = scriptdata }, { id = item.id })

    -- save script data to file
    script.save(item, true)
    -- reload script/group monitor
    script.reloadsingle(item)

    print('update ok')
  else
    print('script not found')
  end
else
  print('invalid arguments')
end

Wow thank you for your responsiveness ! I'll try this soon and keep you inform.
Thx !

RE: Remote script modification - Hippolyte - 20.03.2018

Hello, I have an error when doing exactly what you wrote.

"Error in /www/user/update2.lp at line 5: attempt to index global 'script' (a nil value)"

Can you help me with that please ?

RE: Remote script modification - admin - 20.03.2018

Add require('apps') to the next line after <?

RE: Remote script modification - Hippolyte - 20.03.2018

That's what I did. Now I have "Error in /www/user/update.lp at line 10: '=' expected near ' if'"

RE: Remote script modification - admin - 20.03.2018

Post your full code, you probably modified something by accident

RE: Remote script modification - Hippolyte - 21.03.2018

Code:
<?
require('apps')
name = getvar('name')
scriptdata = getvar('script')
if name and scriptdata then
  item = script.get(name)
  if item then
    item.script = scriptdata
    db:update('scripting', { script = scriptdata }, { id = item.id })
    -- save script data to file
    script.save(item, true)
    -- reload script/group monitor
    script.reloadsingle(item)
    print('update ok')
  else
    print('script not found')
  end
else
  print('invalid arguments')
end

Here it is Smile

Try log variables and check in LM logs what could be the source of problem, like below:

Code:
You can try to log it like this:

<?
require('apps')
name = getvar('name')
scriptdata = getvar('script')

log(1, name, scriptdata)

if name and scriptdata then
  item = script.get(name)
  
  log(2, item)

  if item then
    item.script = scriptdata

    log(3, item.script)

    res = db:update('scripting', { script = scriptdata }, { id = item.id })
    log(4, res)
    -- save script data to file
    script.save(item, true)
    log(5, 'After script.save')
    -- reload script/group monitor
    script.reloadsingle(item)
    print('update ok')
  else
    print('script not found')
  end
else
  print('invalid arguments')
end

Hi,

If this is your full sample then you miss ?> at the end ..

BR,

Erwin

RE: Remote script modification - admin - 21.03.2018

Code is fine, ending ?> is optional. Double check .lp file contents on your device.

@admin, I literally copy paste the code of my update.lp file on my device.
Are you sure for the http://LM_IP/user/update.lp?name=test&script=log(event) ?

@Erwin I did add the ?> yet nothing, as admin said it might be optional

@buuuudzik I tried your test and still -> Error in /www/user/update2.lp at line 11: '=' expected near ' log'

I wonder if this is not an issue about the copy paste from this website to the update.lp file. Like invisible caracters coming in the code ...

RE: Remote script modification - admin - 21.03.2018

You probably have a non breaking space there, either use another code editor or remove all leading spaces from the code.

Whether I put it perfectly like this

Code:
<?
require('apps')
name = getvar('name')
scriptdata = getvar('script')
if name and scriptdata then
  item = script.get(name)
  if item then
    item.script = scriptdata
        db:update('scripting', { script = scriptdata }, { id = item.id })
        script.save(item, true)
        reload script/group monitor
        script.reloadsingle(item)
        print('update ok')
      else
    print('script not found')
  end
else
print('invalid arguments')
end
?>

Or this

Code:
<?
require('apps')
name = getvar('name')
scriptdata = getvar('script')
if name and scriptdata then
item = script.get(name)
if item then
item.script = scriptdata
db:update('scripting', { script = scriptdata }, { id = item.id })
script.save(item, true)
reload script/group monitor
script.reloadsingle(item)
print('update ok')
else
print('script not found')
end
else
print('invalid arguments')
end
?>

I still have "Error in /www/user/update.lp at line 11: '=' expected near 'script'"
when I type http://192.168.1.230/user/update.lp?name=test&script=log(event) in Chrome

RE: Remote script modification - buuuudzik - 22.03.2018

What you have in "Logs" on Logic Machine when you run this code:

Code:
<?
require('apps')
name = getvar('name')
scriptdata = getvar('script')

log(name, scriptdata) -- THIS CODE LOGS VARIABLES IN LM LOGS

if name and scriptdata then
item = script.get(name)
if item then
item.script = scriptdata
db:update('scripting', { script = scriptdata }, { id = item.id })
script.save(item, true)
-- reload script/group monitor
script.reloadsingle(item)
print('update ok')
else
print('script not found')
end
else
print('invalid arguments')
end
?>

I feel so bad ! Sorry for wasting your time and thank you very much all.
It works great !

One last quick question : how do you do a return carriage (new line) ?

RE: Remote script modification - Hippolyte - 30.03.2018

Hello, once again thank you for your help.
So it is working really great. Yet I still have this return carriage issue. If I use the http://LM_IP/user/update.lp?name=test&script=100linesscript then the script is written on only one line when I open it on the LM, do you think there is a way to keep the indentation ?
This is for upgrading script on 500 LMs at the same time Big Grin

RE: Remote script modification - admin - 30.03.2018

You need to use POST request, because GET query string is limited to a certain number of characters

RE: Remote script modification - Leo681 - 26.02.2023

there is anyway to create the script first? i mean create a script from another script.

If its posible how i make the diferent scripts types?

thanks
