Hi, I would like to create an e-mail template for a custom model. the model hast 2 fields. One field many2One to a party.party and one field Many2Many towards party.party. In the e-mail template I am offered to add a field for “recipients”. When clicking, it offers me only the many2one field, the created\_by, edited\_by **but not** the may2many. Is there a way to add the Many2many partys as recipients? Or is there a different approach? Regards Jakob ---

Which email template are you talking about? ---

Indeed the selection constraint is based on the `relation` value of the field. But for `Many2Many` the `relation` is the relation table and not the target so they are not available. I filled [Can not select Many2Many as recipients of email template (#13756) · Issues · Tryton / Tryton · GitLab](https://bugs.tryton.org/13756) if someone wants to improve the support. ---

I saw that there is the possibility to use a PYSON STatement in the char field. I tried with `Eval("self.parents", []),` where parents is the m2m field linking party.party. But it seems to return an empty list. Is it possible that way and i am just having a mistake i the statemet or does that not work at all? ---

Indeed using a `PYSON` expression should work. ---

Do you have a hint for me, how to create that pyson statement, please? `(self.parents,[] )` Does not give me a result, but in Trytond-console I can navigate to the model “member”, that should be the model in “self” and get two party-records with member.parents. ---

It shoudl be `Eval('self', {}).get('parents', [])` ---

> [@ced](#): > > `Eval('self', {}).get('parents', [])` Unfortunately that does not give a result. The statement is rewritten to `Get(Eval("self", {}), "parents", [])` when saving the object. When I use the template from the member model of the cliental- , it does not pull the values. I double checked in the Trytond-Console: ```auto >>> env = EvalEnvironment(mem, Member) >>> mem.parents (Pool().get('party.party')(4), Pool().get('party.party')(3)) >>> b= Eval('parents',[]) >>> PYSONDecoder(env).decode(PYSONEncoder().encode(b)) [4, 3] ``` The statement, as far as I understand, should return the list [4, 3]. ---

In case, someone else has that problem. I read somewhere else in the forum, the statement must return a list of strings containing e-mail addresses. I read as well, that iteration over al list of objects I pyson Is not possible. I now create a Function Field on\_change\_with depending on the m2m field, that extracts a char list of ` name ,` That solution is working. ---
