dbbase.column_types.WriteOnlyColumn.compare

WriteOnlyColumn.compare(other, use_proxies=False, equivalents=None, **kw)

Compare this ColumnElement to another.

Special arguments understood:

Parameters

• use_proxies – when True, consider two columns that share a common base column as equivalent (i.e. shares_lineage())

• equivalents – a dictionary of columns as keys mapped to sets of columns. If the given “other” column is present in this dictionary, if any of the columns in the corresponding set() pass the comparison test, the result is True. This is used to expand the comparison to other columns that may be known to be equivalent to this one via foreign key or other criterion.
