JSON Grammar No Root question

[Zeik]

Hi All,

I have been trying to figure out how to have a JSON grammar with no root as allowed by the JSON standard, is this possible?  Is that what jsonnocheck is for?

Example

{ 

     "name": "Jack", 

     "age": 99

 }

Thanks

Hi Zeik

I am doing this in different places - either in communication scripts or in envelope. But the process is the same:

1. check the grammar and get the element name of the root element
2. read the data and use only the subset of the named element

Something along the line of:

from bots import grammar

def main(channeldict, filename, ta):
  # Get Grammar to remove the 'root' element when sending.
  ta.synall()
  botsgrammar = grammar.grammarread(ta.editype, ta.messagetype, 'grammars')
  rootid = botsgrammar.structure[0][0]

  # Open the file and read json to dict. Later on, dict is sent back to JSON without root.
  infile = open(filename)
  data = json.loads(infile.read())

  data = data[rootid]

Thanks Wassily, will look into using this.

Hi Wassily,

I am not as familiar with using the communicationscripts, I have a channel that is part of a composite route.  The composite route has 2 parts, 1st is the translation and then second is just the output to a folder a passthrough.  Should I attach this script to the second channel which is just the output or is there a way to intercept the file from part 1 of the composite script before it goes to part 2 to run this script (I was thinking maybe a routescript using like postmerge?)  or do I just have the script write to the folder myself since main overrides the channel?  I seem to be misunderstanding how to implement the postprocessing correctly, as I do not understand how to write the file back into bots chain of processing.

Thanks

Made some progress, forgot to set the channel to type: communicationscript (it was previously set to file).  I was able to get it to run but I am unclear on how to put the file back into the process chain to that it outputs to the filepath set in the channel?

I was looking at the routescript examples and wondering if this is the way to push the changed file back into the process chain in the code example Wassily posted ? 

ta_to = ta_from.copyta(status=endstatus) #make new transaction for bots database

ta_to.update(statust=OK,filename=ta_from.filename) #update outmessage transaction (same) filename
