G-d willing

Hello,  
I have an issuer that has a list of offers he received from his customers. On every offer, the issuer is an observer.  
I would like to have a choice where the issuer accepts or rejects all the available offers he has. But I don’t know how to fetch the list of the relevant contracts in a single command.

template A  
with  
issuer: Party  
where  
signatory issuer

```
choice DoBulk: ()
controller issuer
  do
    -- get all the contracts of type B that the issuer is an observer

```

template B  
with  
customer: Party  
issuer: Party  
where  
signatory customer  
observer issuer

You cannot “query” the ledger from within Daml. So you have basically two options here:

- Keep track of things: require that every time an offer is created, it is added to a list in a ListOfOffers contract or similar.
- Query from the client side, and provide the list of offers to accept or reject as an argument to the choice.
