# Upload Version Button Component (Workaround)
|
|
|
|
Activates a file version upload.
|
|
|
|
Until further backend API improvements are implemented, this component is meant to be used
|
|
to enrich the features and decrease the restrictions currently applied to node version uploading.
|
|
|
|
## Basic usage
|
|
|
|
```html
|
|
<adf-upload-version-button
|
|
staticTitle="Upload new version"
|
|
[node]="node"
|
|
[rootFolderId]="node.parentId"
|
|
[versioning]="true"
|
|
(success)="onUploadSuccess($event)"
|
|
(error)="onUploadError($event)">
|
|
</adf-upload-version-button>
|
|
```
|
|
|
|
This component extends the [Upload Button component](upload-button.component.md). The
|
|
properties and events are the same except for the `node` property that specifies the node
|
|
to be versioned (this is a _required_ input parameter). However, some properties don't make
|
|
sense when applied to the Upload Version Button component, so they are simply ignored.
|
|
|
|
## Class members
|
|

|

|
|

|
|
|
|
| Name | Type | Description |

| -- | -- | -- |
|
|
| createFolder | `EventEmitter<Object>` | Emitted when a folder is created. |
|
|
| error | `EventEmitter<Object>` | Emitted when an error occurs. |
|
|
| permissionEvent | `EventEmitter<PermissionModel>` | Emitted when delete permission is missing. |
|
|
| success | `EventEmitter<Object>` | Emitted when the file is uploaded successfully. |
|
|
|
|
## Details
|
|
|
|
### Restrictions
|
|
|
|
Currently, the API only allows new version uploads for a node where the name
|
|
(and most importantly the _extension_) of the new version
|
|
is exactly the same as the old version. As a result, this workaround component uploads the
|
|
chosen file with the same name that the original file had. This is the reason why the `node`
|
|
is a mandatory dependency for this component.
|
|
|
|
So, to sum up, this component:
|
|
|
|
- **Can** upload a new version from the same file extension regardless of the file name.
|
|
- **Cannot** upload a new version that has a different file extension, to the file that was
|
|
originally uploaded (an error message will be emitted by the `error` EventEmitter of the component.
