Hello again.
I am having problems to use the "set" method of "Property" or "Function"
fields. I think my problem has to do with the fact that I don't know the
names of basic field models, but I am not sure.
I am trying to set the value of a "Property" field (I tried with Function
also, but thought Property would be easier to start), when I click on a
button.
In the "set(ids,model,name,value)" i think my problem is in the "model"
field. In my button function I don't have an instance of the model (as to
use *._name), and the names I tried by now didn't work. I suppose that the
required model is the one that the function/property "emulates"
(fields.Function("emulatedField",getter,[...])).
Searching the tryton folders I found that 'ir.property' seems to be the
model name for Property, but that was a special case (most field types are
not included in "ir"). I think that I had seen "Many2Many" as a model name
once, and in the test classes I see "Char", "Integer", etc., stated in the
code, so I can imagine those may be the model names (though they are not
stated in the field definition, it's just my guess). I have tried many
combinations and none worked by now.
The code is as follows:
class Contenido(ModelSQL,ModelView):
'Contenido'
_name = 'many.contenido'
_description = __doc__
name = fields.Char('Nombre')
numero = fields.Integer(u'Número de identificación')
mensaje = fields.Property(fields.Char('Mensaje'))
def botonFun(self,ids):
objProp = Pool().get('ir.property')
for elem in self.browse(ids):
objProp.set(elem.id,'Char','mensaje','hola')
def __init__(self):
super(Contenido,self).__init__()
self._rpc['botonFun']=True
Contenido()
When I click the button I get:
Error:
Traceback (most recent call last):

Any help will be very appreciated.
