# Permissionable

The **Permissionable** component is primarily used to set permissions for authorized addresses to carry out specific actions.

By leveraging this component, developers can build applications where users maintain control over key functions while safely delegating specific tasks to other addresses. Permissioned addresses can also play a minimal role of guardians.

The full contract code of the `PermissionableComponent` can be found [**here**](https://github.com/horuslabsio/TBA/blob/v3/src/components/permissionable/permissionable.cairo)**.**

## Functions

### `_set_permission`

```rust
fn _set_permission(
    ref self: ComponentState<TContractState>,
    permissioned_addresses: Array<ContractAddress>,
    permissions: Array<bool>
);
```

This function assigns or revokes a specific permission to an address for a particular profile.

#### Parameters

| Name                     | Type                     | Description                                                                                                                   |
| ------------------------ | ------------------------ | ----------------------------------------------------------------------------------------------------------------------------- |
| `permissioned_addresses` | `Array<ContractAddress>` | An array of addresses that need permission updates. The length of this array must match the length of the `permissions` array |
| `permissions`            | `Array<bool>`            | A corresponding array of boolean values where `true` grants permission and `false` revokes.                                   |

### `_has_permission`

```rust
fn _has_permission(
    self: @ComponentState<TContractState>,
    owner: ContractAddress,
    permissioned_address: ContractAddress
) -> bool

```

This function checks whether a specific `permissioned_address` has been granted permission by the given account owner.

\
Parameters

| Name                   | Type              | Description                             |
| ---------------------- | ----------------- | --------------------------------------- |
| `owner`                | `ContractAddress` | An instance of the component.           |
| `permissioned_address` | `ContractAddress` | The interface ID to be checked against. |

#### Returns

`bool:`  returns `true` if the `permissioned_address` has been granted permission by the `owner`and `false` if the `permissioned_address` has no permission.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.tbaexplorer.com/contracts/components/permissionable.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
