Char type was converted to wchar_t and then was serialized as utf-8 stream.
Let char type will always be one char, of course it need to be a valid utf-8 sequence.
Let FT::dont_use_utf8 apply only to wchar_t and std::wstring
but ignore it if FT::hexadecimal or FT::binary are defined.
Now we have bool BaseExpression::esc_char(wchar_t val, pt::TextStream & stream) method
which (in most cases) will be used in derived classes.
Let wchar_t (and std::wstring) will be stored as 8 hex digits when using FT::hexadecimal
or FT::binary (and ignore FT::dont_use_utf8 in such a case).
those functions can be used with databases and flat files
- removed support for calling static function
- if MORM_HAS_EZC_LIBRARY macro is defined then we can call a function
which has a first argument Ezc::FunInfo<>& object
(only for generating flat files)
methods before_field_value_string() and after_field_value_string() moved
from DbExpression and JsonExpression to BaseExpression and made virtual
and now methods before_field_value(const std::wstring &) and after_field_value(const std::wstring &)
(and the rest of them with string arguments) can be removed from DbExpression, PostgreSqlExpression and JsonExpression
Now we know whether the primary key is defined or not
and we do not allow to make update/remove if the key is not defined.
And when doing insert/update we can put NULL if child models don't have
the primary key set (fields with has_foreign_key set to true).
Now in after_select() we should also set has_primary_key_set flag
or just call get_last_sequence_for_primary_key instead of get_last_sequence.
fixed: added prefix +00 when serializing PT::Date to PostgreSQL (time zone)
(for a column with a time zone there was a wrong value saved)
fixed: when generating: insert, update or remove statements we have used prefixes for columns
but the table name was not set in ModelEnv (now we do not use prefixes in such statements)
changed: log_queries field moved from PostgreSQLConnector to DbConnector

(this was for a custom prefix)
- removed column_prefix and column_prefix_index from BaseExpression
now we have a pointer to ModelEnv passed in field() method
- to ModelEnv: added table_name, table_name_simple and table_index
git-svn-id: svn://ttmath.org/publicrep/morm/branches/join_models@1193 e52654a7-88a9-db11-a3e9-0013d4bc506e
now in Model we have field() methods for other Model or std::list<Model>
(code not tested)

this allowes us to call query() recursively (from after_select() callback)

- support for inserting/updating rows
