Create requirement type

[Bhuertas]

Hey,

I would like to create a requirement type into a requirement types folder but when I try this method :

req_types_folder = model.oa.requirement_types_folders.create()
req_type = req_types_folder.types.by_class("RequirementType").create()

I get this error :

Traceback (most recent call last):
  File "C:\Users\bahuerta\Capella\capella\workspace\Python4Capella\VSC_Python_scripts\xslx2capella.py", line 27, in <module>
    req_type = req_types_folder.types.by_class("RequirementType").create()
               ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "C:\Users\bahuerta\AppData\Local\Programs\Python\Python311\Lib\site-packages\capellambse\model\_obj.py", line 1466, in create
    raise TypeError("Cannot create elements: List is not coupled")
TypeError: Cannot create elements: List is not coupled

I guess it's because a RequirementTypesFolder.types is not a coupled object but do you know if there is a way to do it ?

I also tried this way :

req_types_folder = model.oa.requirement_types_folders.create()
req_type = req_types_folder.requirement_types.create()

But I had the same error + one saying the function requirement_types was deprecated.

Thank you in advance

When you're doing req_types_folder.types.by_class("RequirementType"), the list of types gets filtered and decoupled from the model. This is fine for getting data out of the model, but it prevents you from making changes. Instead, you have to modify the unfiltered list directly, and pass the type as first argument to the create() method:

req_types_folder.types.create("RequirementType")

In 0.7+, req_types_folder.requirement_types is just a compatibility alias for req_types_folder.types.by_class("RequirementType"), which is why it behaves the same.
