In order to add regions, the function add_region() is used. The respective region name, hierarchy and parent can be defined. If a synonym should be added for a given region, then this must be done using add_region_synonym(). The key is though that the definition of the synonym must be done prior to adding the region.
This can be replicated by carrying out the following code snippet:
import message_ix
import ixmp
mp = ixmp.Platform(name="<database_a>")
mp2 = ixmp.Platform(name="<database_b>")
# Copy units
for u in mp.units():
mp2.add_unit(u)
df = mp.regions()
for i in df.index:
mp2.add_region(region=df.iloc[i].region,
hierarchy=df.iloc[i].hierarchy,
parent=df.iloc[i].parent)
if df.iloc[i].mapped_to is not None:
mp2.add_region_synonym(region=df.iloc[i].region,
mapped_to=df.iloc[i].mapped_to)
The correct way of doing this:
import message_ix
import ixmp
mp = ixmp.Platform(name="<database_a>")
mp2 = ixmp.Platform(name="<database_b>")
# Copy units
for u in mp.units():
mp2.add_unit(u)
df = mp.regions()
for i in df.index:
if df.iloc[i].mapped_to is not None:
mp2.add_region_synonym(region=df.iloc[i].region,
mapped_to=df.iloc[i].mapped_to)
mp2.add_region(region=df.iloc[i].region,
hierarchy=df.iloc[i].hierarchy,
parent=df.iloc[i].parent)
Note, there is not way of modifying and existing entry using the python api.
