Modify schema.rs

In the last step, we changed State to Config.

Now we do it to the schema.rs file too. The variable is imported examples/schema.rs.

Replace instances of State​

Replace the two instances of State with Config.

Generate a schema for Poll and Ballot structs.​

  1. Add Poll and Ballot to the import schema line.
note

This is the same line you just changed from State to Config

Change this: 

use cw_starter::state::Config;

To this:

use cw_starter::state::{Config, Poll, Ballot};
  1. Generate a schema for Poll and Ballot.
export_schema(&schema_for!(Config), &out_dir);
export_schema(&schema_for!(Poll), &out_dir);
export_schema(&schema_for!(Ballot), &out_dir);
  1. Now compile the contract
// This will generate new JSON files, for our config, poll and ballot
cargo schema

//There are 0 tests but should pass
cargo test

//This generates the wasm under target
cargo wasm
  1. Now let's modify instantiation

We want to allow an admin to be specified when a user instantiates the contract using the Option struct.

Currently, InstantiateMsg looks like this:

#[derive(Serialize, Deserialize, Clone, Debug, PartialEq, JsonSchema)]
#[serde(rename_all = "snake_case")]
pub struct InstantiateMsg {
    pub val: String,
}

Let's modify it to this:

#[derive(Serialize, Deserialize, Clone, Debug, PartialEq, JsonSchema)]
#[serde(rename_all = "snake_case")]
pub struct InstantiateMsg {
    pub admin: Option<String>,
}
