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
FT class has following types:
enum FieldType
{
default_type = 0,
primary_key = 1,
foreign_key = 2,
foreign_key_in_child = 4,
no_insertable = 8,
no_updatable = 16,
no_fetchable = 32, /* not supported yet */
};
an object of FT class are now used in Model::field() methods instead of insertable/updatable/is_primary_key/... boolean flags
changed the semantic of has_foreign_key (which was a bool) flag in child Models:
now on Models and list/vector of Models you should use either FT::foreign_key or FT::foreign_key_in_child
1. FT::foreign_key means that field with this flag is a foreign key and is pointing to the child object
(it was the case when has_foreign_key was equal to true beforehand)
2. FT::foreign_key_in child means that the foreign key is in the child object and is pointing to the parent object
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)
methods removed:
virtual void before_field_name();
virtual void after_field_name();
methods added:
virtual void before_short_field_name();
virtual void after_short_field_name();
they are used for escaping column names in a case when using short form - just only column_name
e.g.: [before_short_field_name]column_name[after_short_field_name]
methods added:
virtual void before_first_part_long_field_name();
virtual void after_first_part_long_field_name();
virtual void before_second_part_long_field_name();
virtual void after_second_part_long_field_name();
they are used for escaping column names in a case when using long form: table_name.column_name
e.g.: [before_first_part_long_field_name]table_name[after_first_part_long_field_name].[before_second_part_long_field_name]column_name[after_second_part_long_field_name]
methods added:
virtual void esc(wchar_t val, PT::TextStream & stream);
we can use our own class (based on FlatConnector and FlatExpression) to generate documentation
git-svn-id: svn://ttmath.org/publicrep/morm/trunk@1213 e52654a7-88a9-db11-a3e9-0013d4bc506e
an additional field (model_save_mode) is printed
changed: if there is no an object the Cursor returns a Model with DO_NOTHING_ON_SAVE flag now
(DO_INSERT_ON_SAVE was beforehand)
fixed: when reading a result from db: for auto generated select there should be used
get_value_by_field_index() method instead of get_value_by_field_name()
changed: flat string (json) is generated only if a model has DO_INSERT_ON_SAVE
or DO_UPDATE_ON_SAVE or is dump_mode turn on
git-svn-id: svn://ttmath.org/publicrep/morm/trunk@1208 e52654a7-88a9-db11-a3e9-0013d4bc506e
added BaseExpression::need_to_add_field_prefix()
now the fields() methods don't take add_column_prefix parameter
but the field_name (wchar_t*) is tested whether is it a long (with a period) or short name
added BaseExpression::save_foreign_key() (code moved from field())
removed some default method arguments from BaseExpression
added neq() method for Finder
added DbExpression::prepare_short_table_name(const PT::TextStream & table_name, PT::TextStream & short_table_name)
git-svn-id: svn://ttmath.org/publicrep/morm/branches/join_models@1194 e52654a7-88a9-db11-a3e9-0013d4bc506e
(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
- added FinderHelper class - used as a global object for the whole model tree in Finder
(some fields moved from ModelData)
- added CursorHelper class - used as a global object for the whole model tree in Cursor
(some fields moved from ModelData)
git-svn-id: svn://ttmath.org/publicrep/morm/branches/join_models@1192 e52654a7-88a9-db11-a3e9-0013d4bc506e
added: ModelEnv class - now Model has a pointer to ModelEnv
and ModelEnv has a pointer to ModelData, model_connector_mode, table_index and doc_field_pointer
git-svn-id: svn://ttmath.org/publicrep/morm/branches/join_models@1191 e52654a7-88a9-db11-a3e9-0013d4bc506e
(the primary key should consist of only one column at the moment)
git-svn-id: svn://ttmath.org/publicrep/morm/branches/join_models@1186 e52654a7-88a9-db11-a3e9-0013d4bc506e
added: using ModelData in BaseExpression so Model::to_text() functions can use a ModelData object now
git-svn-id: svn://ttmath.org/publicrep/morm/trunk@1175 e52654a7-88a9-db11-a3e9-0013d4bc506e
now in Model we have field() methods for other Model or std::list<Model>
(code not tested)
git-svn-id: svn://ttmath.org/publicrep/morm/trunk@1118 e52654a7-88a9-db11-a3e9-0013d4bc506e
- support for fetching rows from db
- support for inserting/updating rows
git-svn-id: svn://ttmath.org/publicrep/morm/trunk@1081 e52654a7-88a9-db11-a3e9-0013d4bc506e
