It makes no senses to have the getter method of Function field
creating
instances.
Well I think Sergi's use case is valid. He does not create instances,
he just
wants to display computed data, which is precisely the point of Function
fields.
I think you can do it in read of the ModelView returning a list of
dictionaries with key 'id' and values for all fields_names. Also I
guess you need to implement search by your own. The getter of the
function.field need to return a dictionary with the ids you want to
compute.
An exampe what we did once (in 2.4):
Thanks for sharing your code, but i find it too complex. I solved the
issue with overriding the __init__ function of the models to accept a
dict as id parameter and returning a list of dicts in may fucntion
field. That's the code of the modelview:
/
//class ExtraProductLine(ModelView): //
//'ExtraProductLine' //
// __name__ = 'production.extra_product.line' //
////
// description = fields.Char('Description') //
// quantity = fields.Float('Quantity') ////
////
// def __init__(self, id=None, **kargs): //
// #Id is returned by function fields, //
// if id and isinstance(id, dict): //
//kargs.update(id) //
// id = None //
// super(ExtraProductLine, self).__init__(id, **kargs) /
You need ActiveRecord (>2.6 I think) to get this code working.
As I think is not the best way to solve it. So I openend an issue :)
