Hi,
Something like:
from osgeo import ogr
original_field_names = [ "toolongforshapefile1", "toolongforshapefile2"]
map_to_shp = {}
tmpfilename = "/vsimem/temp.shp"
ds = ogr.GetDriverByName("ESRI Shapefile").CreateDataSource(tmpfilename)
lyr = ds.CreateLayer("temp")
lyr_defn = lyr.GetLayerDefn()
for name in original_field_names:
lyr.CreateField(ogr.FieldDefn(name))
shp_field_name = lyr_defn.GetFieldDefn(lyr_defn.GetFieldCount() -
1).GetNameRef()
map_to_shp[name] = shp_field_name
ds = None
ogr.GetDriverByName("ESRI Shapefile").DeleteDataSource(tmpfilename)
print(map_to_shp)
Even

Hi everyone,
I want to make a map of original (let's say postgresql/postgis) column
names to those used in a shapefile after conversion; assuming that at
least some column names in postgis will be over 10 characters in
length, and shortening may produce conflicts. Basically I know how
this is done, appending _<n>, but I hope that there is preferably a
python method available in Qgis python to get the list of column names
used in the shapefile.
Any help or pointers are welcome!
Thanks,
Jan
