It is also possible to route the the `select_by` and `get_by` functions on `Query` using the new property name, by establishing a `synonym`:
{python}
- mapper(MyClass, mytable, proeprties = {
+ mapper(MyClass, mytable, properties = {
# map the '_email' attribute to the "email" column
# on the table
'_email': mytable.c.email
Synonym can be established with the flag "proxy=True", to create a class-level proxy to the actual property:
{python}
- mapper(MyClass, mytable, proeprties = {
+ mapper(MyClass, mytable, properties = {
'_email': mytable.c.email
'email' : synonym('_email', proxy=True)
})
