How to add an error to validateDeviceConfigUi

Greetings,

I use 5 EasyDAQ relay/DIO boards. I would like to add some code to validateDeviceConfigUi in plugin.py so that if I try to add a channel (mirror device) for a board and that channel is already used I would get a warning and be prevented from adding it as a mirrored device.

I have com up with the following:

Code: Select all

inUseList = []

isRelay = ('relay %d' %valuesDict["channelSel"])
         
inUseList = [dev.name for dev in indigo.devices]
         
if isRelay in inUseList:         
   errorsDict["channelSel"] = u"relay is already configured"

This works gut with one board but not with multiple boards because other boards have the same channel number. Thus it may see a duplicate channel and give the error but the channel is really from another board (because my code gets all the devices). What I need to get is the list of devices for the inUseList but only for the current device selected but I cannot find a way to do this?

Is it possible for you to give me some direction?

Thanks to you,

Z

You're talking about modifying the EasyDAQ plugin? That's really not recommended since your changes will get overwritten every time we upgrade Indigo...

Greetings,

Yes it is for the EasyDAQ plugin I made my question to reference. I copy over my reworked plugin if there is an update to the software. This not an inconvenience for me.

I have already made changes to the plugin to be able to select an input as a mirror device so it shows in the main UI. Also I have removed the all plugin ACTIONS because I only use my EasyDAQ boards for ON/OFF/Toggle and control the Inputs and Outputs as Devices. This works extremely well for my application and this exercise has given me much understanding of plugin constructions.

I hope you do not mind too much me adjusting your plugin for my use and that you may answer the question to which I posed in the earlier posting.

Kind regards,

Z

No problem at all for you hacking the plugins for your personal use.

Take a look at the method _addMirrorDevToMap() in the plugin. Note that the plugin keeps track of all mirrored devices inside the self.mirrorDevMap dictionary. Also look at _lookupMirrorDevIterFromMap(). It should be able to tell you if a mirror device given a parent ID and channel ID exists or not. Not positive that is what you are after, but I think it might be.

Greetings,

Much thanks for your suggestion. Using your recommendation I came up with the following code added to the "validateDeviceConfigUi" method and it now gives an error if a mirror device is added while it already exists in the UI.

Code: Select all

#hack - give error if trying to add device twice            
dupDev = ('%s.%s' %(valuesDict["deviceSel"], valuesDict["channelSel"]))
        if dupDev in self.mirrorDevMap:
              errorsDict["channelSel"] = u"mirror device has already been added to UI"

thanks to you,

Great – I'm glad you got it working.
