Convert sotrage for pallet v2. Need help!

[herou]

The title is very descriptive.

I would like to convert this

into V2. Below I have my translated version but it seems not working:

@JoshOrndorff Can you please take a look and tell me what's wrong. I would really appreciate it. Note: Some tests are failing Pallet link: https://github.com/herou/recipes/tree/recipes_pallet_v2/pallets/charity

You weren't calling the genesis config for the charity pallet. I changed the code slightly to do that, but then I got a challenging compile error

  --> pallets/charity/src/tests.rs:99:4
   |
99 |         .assimilate_storage(&mut t)
   |          ^^^^^^^^^^^^^^^^^^ method not found in `Result<(), std::string::String>`

error: aborting due to previous error

For more information about this error, try `rustc --explain E0599`.
error: could not compile `charity`

I'm guessing maybe you encountered this since there was some commented code around that area. The solution is to call assimilate_storage as a static method so you can explicitly tell it the type parameter. I can't say I understand 100% why it couldn't infer the type. I wish it could.

But this trick of calling as a static method is worth knowing.
