This topic discusses the configuration classes of the PLANTA link API.
Classes
Config
The Config class is the base class that wraps a record from table 560
- It allows you to query almost all of the attributes a configuration has
- You can create new configurations by calling
Config.create()and new mappings by callingConfig.create_mapping() - If you do not know wheter your task requires a
Configor aStaticConfig, then it's most likely you should use aStaticConfigfor better performance
Static variables
| Variable | Description |
|---|---|
| Config.DEFAULT_LOG_LEVEL | This configures the default Log-Level when a new Config is created with Config.create() and no explicit log level is given. The default is PLANTALogLevel.INFO |
| Config.DEFAULT_LOG_TYPE | This configures the default Log-Typ when a new Config is created with COnfig.create() and no explicit log type is given. The default is PLANTALogType.PLANTA_LOGGING |
Methods
| Function | Parameters | Return Value | Description |
|---|---|---|---|
Config.__enter__(self) | Config instance | Enters the context. | |
Config.__eq__(self, other) | other: Another Config instance | True or False | Check whether a Config is equal to another |
Config.__exit__(self, *exc_details) | exc_details: Exception details | Deletes the instance when the context is left | |
Config.__hash__(self) | Integer | Returns a hash based on UUID | |
Config.__init__(self, config_id) | config_id: UUID | Config instance or None if the config_id is not valid | Initializes a new Config object |
Config.copy(self, invoker_module, pass_on_config_hash=True) | invoker_module: A module instance pass_on_config_hash: True or False | Copied instance or None | Makes a copy of a configuration. The class of the child is based on the class of the invoking config instance. When pass_on_config_hash is True, the parent will be sanity-checked before copying and the hash is only passed on if the parent was valid. |
Config.create_mapping(self, type, creation_parameters) | type: ppms.interface.MappingType creation_parameters: Any python id from table 562 that should have a custom value | Newly created mapping | Creates a new mapping that belongs to this configuration |

Config.delete_mappings(self) | Deletes all mappings that belong to this configuration | ||
Config.delete_parameters(self) | Deletes all parameters that belong to this configuration | ||
Config.generate_and_clean_up_parameters(self) | Populates the parameter table with the parameters defined by the source/pool/target module of this configuration. Superfluous parameters are removed. Note that this has no effect on a finished configuration. | ||

Config.get_specific_mappings(self, mapping_type) | mapping_type: ppms.interface.MappingType | A list of mappings | Get a list of mappings of a specific type |
Config.get_step_one_mapping(self) | A list of mappings | Get all source mappings that are relevant for the source -> pool transfer step. The mappings returned by this function are a copy of the internal data structure with children that are not relevant for step one removed. | |
Config.get_step_two_mapping(self) | A list of mappings | Get all the source and pool mappings that are relevant for the source/pool -> target transfer step. The mappings returned by this function are not a copy of the internal data structure. | |
Config.get_target_mapping(self) | A list of mappings | Get a list of all target mappings | |
Config.get_validation_hash(self) | UUID | Calculate a hash over all parts of an interface that can be modified by the user and sanity-checked by PLANTA link. | |
Config.modify_parameter(self, source, key, value, system_id=None) | source: MOD of the module which defines the parameter key: The name of the parameter value: The value that it should be set to system_id: UUID | Modify a parameter of a configuration. When system_id is None, the parameter is changed in the currently active system. |
Classmethods
| Function | Parameters | Return Value | Description |
|---|---|---|---|
Config.create(cls, creation_parameters) | creation_parameters: Any python id from table 560 that should have a custom value | A instance of the newly created configuration. The class is based on the class which calls create(). | Create a new configuration record. If the configuration could not be created a ValueError is raised. |

StaticConfig
The StaticConfig class is a more performant version of the Config class
- Instead of lazy-loading the mapping when it is requested, the
StaticConfigclass fetches all mappings when initializing the class - This means that if you make any modification to the mapping of the interface, the
StaticConfiginstance will not know about the changes until you callStaticConfig.refresh() - This class is much faster for executing and sanity-checking interfaces, but slower when you create interfaces programmatically
Methods
| Function | Parameters | Return Value | Description |
|---|---|---|---|
StaticConfig.refresh(self) | Calling refresh() will trigger an instance fetch of all of its mappings again and update the internal state |
RegtestConfig
The RegtestConfig class is used for unittesting PLANTA link
- By default it doesn't write its log data into the database or filesystem but instead it just keeps it in RAM
- Instead of logging errors, it raises a
ValueErrorwhenRegtestConfig.error()is called
Static variables
| Variable | Description |
|---|---|
| RegtestConfig.DEFAULT_LOG_LEVEL | This configures the default Log-Level when a new RegtestConfig is created with RegtestConfig.create() and no explicit log level is given. The default is PLANTALogLevel.DEBUG |
| RegtestConfig.DEFAULT_LOG_TYPE | This configures the default Log-Typ when a new RegtestConfig is created with RegtestConfig.create() and no explicit log type is given. The default is PLANTALogType.STREAM_LOGGING |
