now method put_field_name() is not making a test whether field_name is in long format
and only puts the field name (without table name),
this allows us to have a dot in the column name (field_name)
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);
fixed: compilation erorr when inserting/updating a Model object which has child lists without Model objects such as std::list<int>
added: to Model: methods insert, update, remove and save with one argument: bool save_whole_tree
git-svn-id: svn://ttmath.org/publicrep/morm/trunk@1217 e52654a7-88a9-db11-a3e9-0013d4bc506e
fixed: a parent key was not set in list of childs (insert statements)
git-svn-id: svn://ttmath.org/publicrep/morm/trunk@1215 e52654a7-88a9-db11-a3e9-0013d4bc506e
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
added: ModelEnv::model_connector_submode (used in iterating through childs)
git-svn-id: svn://ttmath.org/publicrep/morm/trunk@1211 e52654a7-88a9-db11-a3e9-0013d4bc506e
added: now we set flag save_mode = DO_NOTHING_ON_SAVE for objects for which
all fields from a database result set are null
git-svn-id: svn://ttmath.org/publicrep/morm/trunk@1210 e52654a7-88a9-db11-a3e9-0013d4bc506e
we do not use auto generated 'select' and when we are using prefixes for columns
git-svn-id: svn://ttmath.org/publicrep/morm/trunk@1209 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
it's a much simpler structure now
removed: FieldValueBase and FieldValueContainer
git-svn-id: svn://ttmath.org/publicrep/morm/trunk@1207 e52654a7-88a9-db11-a3e9-0013d4bc506e
for setting a parent key id in child models,
it is called after after_insert() method
added: SetFieldValueHelper class used for storing primary key values from a parent model
git-svn-id: svn://ttmath.org/publicrep/morm/trunk@1204 e52654a7-88a9-db11-a3e9-0013d4bc506e
