Tomasz Sowa a4a1acebeb add Finder::like(...) and ilike(...) methods 2022-12-05 06:36:13 +01:00
Tomasz Sowa 0bdabfc7b4 fix: put 'char' type directly to the output stream
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).

Tomasz Sowa 48d515ea64 if pt::Space has FT::json type then let JSONExpression serialize it as json and not string 2022-02-03 11:18:01 +01:00
Tomasz Sowa c25a5d2215 - code from JSONExpression::esc(char val, ...) moved to Pikotools (convert/misc.h)
- added ModelContainerWrapper::set_iterator_at_first_model() method

Tomasz Sowa aeb02f82b1 changed the way how we get a specific field value - now we do not use expressions (BaseExpression), to get the raw value we don't need an expression object:
- removed MORM_WORK_MODE_GET_SPECIFIC_FIELD_VALUE from expression work mode
- removed: void BaseExpression::field(const wchar_t * field_name, void (Model::*getter_method)(pt::TextStream &), const FT & field_type, ModelEnv * model_env)
- removed from BaseExpression: template<typename FunInfoStreamType> void field(const wchar_t * field_name, void (Model::*fun)(Ezc::FunInfo<FunInfoStreamType> &), const FT & field_type, ModelEnv * model_env)
- removed: void FlatConnector::to_text(const wchar_t * flat_field_name, pt::TextStream & stream, Model & model)
- renamed/changed: Model::put_field_value(...) -> Model::get_raw_value()

added classes:
class ModelWrapper - base wrapper class for a model or a model container
class ModelWrapperModel : public ModelWrapper - wrapper for a model
template<typename VectorType> class ModelWrapperVector : public ModelWrapper - wrapper for vector of models
template<typename ListType> class ModelWrapperList : public ModelWrapper - wrapper for list of models
ModelWrapper... classes are used by ezc library for iterating through child models and for iterating in [for...] statements

added to Model:
Model * get_model(const wchar_t * db_field_name, const wchar_t * flat_field_name, bool put_log_if_not_found = true);
ModelWrapper * get_model_wrapper(const wchar_t * db_field_name, const wchar_t * flat_field_name, bool put_log_if_not_found = true);

Tomasz Sowa 515e806a50 start adding support for Ezc library - Ezc::Generator is able to get variable value and call a static function 2021-05-31 18:40:28 +02:00
Tomasz Sowa 34274ca230 namespace PT renamed to pt 2021-05-20 16:25:01 +02:00
Tomasz Sowa 2ad6c8c258 changed the way how to quote schemas, tables and field names,
added escaping table names in insert/update/remove

removed methods from BaseExpression:
virtual void before_short_field_name();
virtual void after_short_field_name();
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();

added methods to BaseExpression:
virtual void schema_table_separator();
virtual void table_field_separator();
virtual void before_schema_name();
virtual void after_schema_name();
virtual void before_table_name();
virtual void after_table_name();
virtual void before_field_name();
virtual void after_field_name();

Tomasz Sowa aadc5be350 FT field_type changed to const FT & field_type in functions arguments 2021-05-12 04:53:23 +02:00
Tomasz Sowa 009955a0fd added support for hex strings and binary strings
added FT::hexadecimal, FT::binary and FT::dont_use_utf8
2021-05-11 22:11:31 +02:00
Tomasz Sowa 7bef1d5ead added support for PT::Space as a field in a Model
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

Tomasz Sowa 133a45c84b Added flag has_primary_key_set to Model
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)

Tomasz Sowa ff551a64b8 in BaseExpression: changed the way how field names are escaped:
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);

Tomasz Sowa 958e89fb02 some work in branches/join_models
- 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)
