Usage
1. Message fields access
The library provides a convenient way for Message fields access.
Instead of this:
msg.fields['BO5Items'].list_value.values[0].message_value.fields['segment_instance_number'].message_value.fields['segment_number'].simple_value
You can do this:
import th2_common_utils
msg['BO5Items'][0]['segment_instance_number']['segment_number']
2. Converters
message_to_dict(message)- note, you will lose all metadata of the Message.dict_to_message(fields, session_alias, message_type)- where:- fields - required argument - message fields as a python dict;
- session_alias and message_type - optional arguments - used to generate message metadata.
dict_to_root_message_filter(message_type, message_filter, metadata_filter, ignore_fields, check_repeating_group_order, time_precision, decimal_precision)- all arguments are optional.message_to_typed_message(message, message_type)- where:- message - Message object;
- message_type - TypedMessage class object.
message_to_table(message)- where:- message - Message object or dict.
To import functions above:
from th2_common_utils import message_to_dict, dict_to_message # ...
