How to specify namespace for mapFields through component props

[max-frai]

I want to pass namespace from vuex module with props but it seems to be impossible.

<my-component namespace="ns1" />

// my-component code
export default {
  props: ["namespace"],
  computed: {
    ...mapFields(??this.namespace??, ["attr1", "attr2"])
  }
}

Of course, there is no way to use this in such way so we don't have access to props. How can I specify namespace as prop in such case?

I found a dirty workaround. I rewrote method mapFields and calculate getterType in runtime:

    ...
    const field = {
      get() {
        var getterType = `${this.namespace}/getField`;
        return this.$store.getters[getterType](path);
      },
      set(value) {
        var getterType = `${this.namespace}/updateField`;
        this.$store.commit(mutationType, { path, value });
      }
    };
    ...

Of course, this required namespace to be declared. I understand this is dirt and not for general usage, but maybe it's possible to rewrite mapFields with such functionality?

If it's okay, I can write pull request modifying mapFields with ability to specify inner prop name that we should use in runtime for namespace calculating.

Hey @max-frai! Thank you for your input. If I understand it correctly, this is a duplicate of #24, please use the existing issue for further discussion (if it is no duplicate, please let me know and I'll reopen this issue).

I'll consider accepting a pull request if it can be done in a backwards compatible manner and I'm happy with the resulting API.

Thank you for contributing!
