Tomasz Sowa a4a1acebeb add Finder::like(...) and ilike(...) methods 2022-12-05 06:36:13 +01:00
Tomasz Sowa 43dfbd5d5a add possibility of calculating how many rows there were before LIMIT was applied
The Finder has get_rows_counter() method which returns how many rows there were
before LIMIT clause was applied. The select(...) method should be called with
Select::with_rows_counter flag in such a case.

while here:
- change the semantic of Finder, now the select(...) method takes a morm::Select flags,
  and we have such flags:
  - Select::no_auto_generated_columns - do not generate columns from models
  - with_rows_counter - add an additional column for the rows counter
- remove Finder::prepare_to_select() - now use select(...) with no_auto_generated_columns flag

Tomasz Sowa 1ad3d89d52 change headerfile_morm_* macros to headerfile_morm_src_* 2022-06-30 13:28:38 +02:00
Tomasz Sowa 0ce7578de3 fix: the way how we test if there is a connection issue
If there is a connection issue then PQexec returns a resultset now
- older versions of PostgreSQL returned null pointer.

Tomasz Sowa 12232bf722 propagate status from childs in Model::insert, Model::update, Model::remove and Model::save 2022-05-24 23:27:07 +02:00
Tomasz Sowa dc6c70499c added: Wrapper class as a wrapper for: a model, model container (list/vector), Space or Date
added BaseObjectWrapper as base class for: SpaceWrapper and ModelContainerWrapper
removed: ModelWrapperModel, now one Model doesn't need a wrapper
renamed: ModelWrapperSpace -> SpaceWrapper, now as a base class it has BaseObjectWrapper
renamed: Model::get_model_wrapper() -> Model::get_wrapper() - now it returns Wrapper object
removed logging from Model::get_model() and Model::get_wrapper()
field() methods don't take ModelWrapper** but Wrapper& now
2021-07-01 22:55:56 +02:00
Tomasz Sowa a8fe798279 fixed: getters method (Model::*getter_method)(pt::Stream &) produced boolean value when serializing to flat string
- changed in Model::field_list_generic(...): message "you should set FT::is_foreign_key or FT::is_foreign_key_in_child flag" print only
  for work mode MORM_MODEL_WORK_MODE_SET_PARENT_ID or MORM_MODEL_WORK_MODE_ITERATE_THROUGH_CHILDS_WITHOUT_FOREIGN_KEY
- pt::TextStream::to_string(...) is now pt::TextStream::to_str(...)
- in Model::get_raw_value() for ezc 'pt::TextStream & stream' changed to 'pt::Stream & stream' (a base class of pt::TextStream)
  similar in field(...) methods which take getters: void (Model::*getter_method)(pt::TextStream &) -> void (Model::*getter_method)(pt::Stream &)
2021-06-20 17:49:54 +02:00
Tomasz Sowa aba454a4bf methods Model::get_raw_value(...) now returns boolean - true if a field was found 2021-06-19 20:25:38 +02:00
Tomasz Sowa 9a142548d0 fixed in Model::field_generic_put_raw_value_to_stream() - a boolean status for ezc was not set
added to Model:
- method field() which can take a pointer to a member which returns bool:
  void field(const wchar_t * field_name, bool (ClassName::*method)(), const morm::FT & field_type = morm::FT::default_type)
- method field() which can take a pointer to a member which can set morm::ModelWrapper object
  void field(const wchar_t * field_name, void (ClassName::*method)(morm::ModelWrapper **), const morm::FT & field_type = morm::FT::default_type)
- methods: bool Model::convert_to_bool(...) - they are used for creating a result for ezc from local fields
2021-06-18 19:05:50 +02:00
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);
2021-06-16 14:01:07 +02:00
Tomasz Sowa dd01fafa40 - added support for calling member functions (setters/getters) from Models
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)
2021-06-01 19:34:34 +02:00
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 de4abeb91c added to Finder: methods eq() and similar with table_name as an argument
Finder<ModelClass> & eq(const wchar_t * table_name, const wchar_t * field_name, const FieldValue & field_value)
Finder<ModelClass> & eq(const wchar_t * table_name, int table_index, const wchar_t * field_name, const FieldValue & field_value)
and similar for neq(), lt(), gt(), le(), ge() and in()
2021-05-13 19:32:31 +02:00
Tomasz Sowa 1c5d32551a fixed: a null was printed for id when serializing lists/vectors
in BaseExpression::put_field_value_list(): has_primary_key_set flag was not copied to model_env
2021-04-14 16:21:10 +02:00
Tomasz Sowa f7490594ad changed the way how the table name is set in a Model - added prepare_table() method
removed from Model:
virtual void table_name(PT::TextStream & stream);

added to Model:
virtual void prepare_table();
virtual void table(const wchar_t * table_name);
virtual void table(const wchar_t * schema_name, const wchar_t * table_name);
2021-03-11 12:22:37 +01:00
Tomasz Sowa fcf1d28b18 added FT class which is used in Model::field() methods
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
2021-03-10 16:20:11 +01:00
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)
2021-03-09 18:10:34 +01:00
Tomasz Sowa a5d5a81a57 removed: doc functionality (generating documentation from a model)
we can use our own class (based on FlatConnector and FlatExpression) to generate documentation

Tomasz Sowa 057d879b4c added: to Model::to_text() methods added dump_mode (bool) parameter
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
