Reading External Datagroup files via iControlREST

bump

The process for uploading external dg is typically

1. Upload file
2. Import file via sys/file/ifile
3. Create ltm ifile reference to that file object

If you query that object file object, you end up with many attributes, none of which include the filename created in the filestore. But one attribute is

sourcePath

To answer your question, it IS possible to read the file, but you will need to do some bash calesthenics to interrogate the filestore to get the filename, but even then you still need to download the file to edit it.

Jason, as you have always been very helpful ... Would you please guide me here too. As per above post, I able to read the list of data group files using python SDK.

BigIP Version : 12.1.2 HF2

Now I am trying to read contents of each file. Below is my code but it is erroring out :

    dglist = mgmt.tm.util.bash.exec_cmd('run', utilCmdArgs='-c "ls /config/filestore/files_d/Common_d/data_group_d"')

     Write to a file and then read it line by line 
    dgfile = open("dgfilelist","w")
    dgfile.write(dglist.commandResult)
    dgfile.close()

    dgfile = open("dgfilelist","r")
    for line in dgfile:
      print ("File name is : "+line)
      cmdargs = "'run',"+" utilCmdArgs="+"'-c "+"\"cat /config/filestore/files_d/Common_d/data_group_d/"+line+"\"\'"
      print ("CmdArgs are : "+ cmdargs )
      dgshow = mgmt.tm.util.bash.exec_cmd(cmdargs)
      print ("File Contents are :")
      print (dgshow.commandResult)

Here is the Output :

Shoaib-Mac:f5-sdk mshoaib$ ./p get-datagroup.py 
    File name is : :Common:testvip_PH_16641_18

    CmdArgs are : 'run', utilCmdArgs='-c "cat /config/filestore/files_d/Common_d/data_group_d/:Common:testvip_PH_16641_18
    "'
    Traceback (most recent call last):

    "' does not exist. Valid commands are ['run']
    Shoaib-Mac:f5-sdk mshoaib$

I have tried different iterations to supply a file name to the "exec_cmd" function but it's always angry ...

I appreciate any help or pointers to do it correctly.

Thank you, Muhammad

dgshow = mgmt.tm.util.bash.exec_cmd('run', utilCmdArgs='-c "cat /config/filestore/files_d/Common_d/data_group_d/{0}"'.format(file_name))

I hope its ok to bring this thread back to the top. I am new to rest and I can't figure out how to just read the contents of the external data group file. I can do it fine for internal but seem I can't do exactly the same for external. Any help is much appreciated.
