Call init from child classes like so:

    super().__init__(aPK_obj = aPK_obj, row = row, link_obj = link_obj)

Args

aPK_obj

retrieve data from backend

• a simple value the primary key WHERE condition must be a simple column
• a dictionary of values the primary key WHERE condition must be a subselect consuming the dict and producing the single-value primary key

row

must hold the fields

• idx: a dict mapping field names to position
• data: the field values in a list (as returned by cursor.fetchone() in the DB-API)
• pk_field: the name of the primary key field OR
• pk_obj: a dictionary suitable for passed to cursor.execute and holding the primary key values, used for composite PKs

  row = {

class cAllergyState (aPK_obj: int | dict = None, row: dict = None, link_obj=None)

Represents the allergy state of one patient.

See ALLERGY_STATES for the meaning of cAllergyState['has_allergy'].

Call init from child classes like so:

    super().__init__(aPK_obj = aPK_obj, row = row, link_obj = link_obj)

Args

aPK_obj

retrieve data from backend

• a simple value the primary key WHERE condition must be a simple column
• a dictionary of values the primary key WHERE condition must be a subselect consuming the dict and producing the single-value primary key

row

must hold the fields

• idx: a dict mapping field names to position
• data: the field values in a list (as returned by cursor.fetchone() in the DB-API)
• pk_field: the name of the primary key field OR
• pk_obj: a dictionary suitable for passed to cursor.execute and holding the primary key values, used for composite PKs
• for example:

  row = {
          'data': rows[0],
          'idx': idx,
          'pk_field': 'pk_XXX (the PK column name)',
          'pk_obj': {'pk_col1': pk_col1_val, 'pk_col2': pk_col2_val}
  }
