[GRASS-dev] bug in python version of v.db.renamecol / db_describe ?

[Moritz Lennert]

Glynn,

Trying to debug the v.db.renamecol bash version, I also tried with the 
python version and it seems there is a bug, which IIUC should be fixed 
by the following patch. Can you confirm or do I misunderstand how 
db_describe works ?

      # describe old col
      oldcoltype = None
-    for f in grass.db_describe(table):
+    for f in grass.db_describe(table)['cols']:
         if f[0] != oldcol:
             continue
         oldcoltype = f[1]


Just not familiar enough with the python lib, yet, to feel comfortable 
committing myself.
