update of df for multiple rows fails/not user friendly

[AnkurArohi]

• Do you want to request a feature or report a bug?

• What is the current behavior?
  Trying to set a boolean value for all rows in generator df is difficult/leads to error

  powsybl_net is powsybl network

  a = powsybl_net.get_generators()
  a.voltage_regulator_on = True
  powsybl_net.update_generators(a)

  Error

  Traceback (most recent call last):

    return self._update_elements(ElementType.GENERATOR, df, **kwargs)
  

  , line 2103, in _update_elements
  _pp.update_network_elements_with_series(self._handle, c_df, element_type)
  pypowsybl._pypowsybl.PyPowsyblError: Series 'name' is not modifiable.

  Although

  a.name==powsybl_net.get_generators().name

  Is True for all rows

• If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem

• What is the expected behavior?
  It should be easy to update column values for each row in df

something like this

powsybl_net.get_generators().loc[:,"voltage_regulator_on"] = True

• What is the motivation / use case for changing the behavior?

User friendliness

• Please tell us about your environment:

  • PowSyBl Version: ...
  • OS Version: ...

• Other information (e.g. detailed explanation, stacktraces, related issues, suggestions how to fix, links for us to have context, eg. stackoverflow, spectrum, etc)

Hello, you can do it like that

net.update_generators(id=net.get_generators().index, voltage_regulator_on=[True]*len(net.get_generators().index))

Hello, you can do it like that

net.update_generators(id=net.get_generators().index, voltage_regulator_on=[True]*len(net.get_generators().index))

Thanks for your reply, Yes but I find this not user friendly, thats why i mentioned that this is not a bug, but this is according to me not an elegant way of doing it
