implement store_code_with_id helper

[Art3miX]

I'm working on a migrator contract which handles migrations of different contracts from V1 to V2, the V1 code ids are known and can be static inside the contract and I need to compare those with the given contracts to make sure im talking only with our modules, but with current store_code I can't test it with multi-test. (as a work around I am providing both code id sets from the front-end)

It can be done in 2 ways, either create another function store_code_with_id that will handle it specifically, or add an optional field of id to current store_code.

pub fn store_code_with_id(code, id)

We can store the highest provided code id in self.last_code_id, so "original" store_code() will be able to work, instead of using self.codes.len(), it will use the last_code_id.
Add a test that will check if the provided code id already exists results in an error.

It will cater to a specific use cases of testing contract code id against a static code id provided inside the contract, but those cases might increase as time pass on.

Hi @Art3miX, is your case still relevant? If yes, would it be possible to take a look at your tests? Thanks in advance.

Hi @Art3miX, could you provide a link to your tests where you use this technique, just to have better understanding of your use-case? Maybe we can provide more general solution? Thanks in advance.

Hey @DariuszDepta, sorry for the late reply, totally missed this.

Here is the contract in question: https://github.com/DA0-DA0/dao-contracts/tree/development/contracts/external/dao-migrator
It is a migrator from v1 to v2 of Dao Dao, the v1 code ids are known and can be hardcoded into the code instead of passing any extra data.

Allowing setting a code id in test can make it possible to test those cases.
