# DestinationProject

## Introduction

**`DestinationProject`** widget in Supervisely provides several options for selecting the destination project and dataset when transferring data. Users can choose between creating a new project or selecting an existing project, as well as creating a new dataset or selecting an existing dataset within the project. `DestinationProject` also includes an input field where users can enter the name of the destination project or dataset when creating a new one. This flexibility allows users to easily manage and organize their projects and datasets within the platform.

## Function signature

```python
DestinationProject(
    workspace_id=654,
    project_type="videos",
    widget_id=None,
)
```

## Mini App Example

You can find this example in our Github repository:

[supervisely-ecosystem/ui-widgets-demos/selection/011\_destination\_project/src/main.py](https://github.com/supervisely-ecosystem/ui-widgets-demos/blob/master/selection/011_destination_project/src/main.py)

### Import libraries

```python
import os

import supervisely as sly
from dotenv import load_dotenv
from supervisely.app.widgets import Button, Card, Container, DestinationProject, Text
```

### Init API client

First, we load environment variables with credentials and init API for communicating with Supervisely Instance:

```python
load_dotenv("local.env")
load_dotenv(os.path.expanduser("~/supervisely.env"))

api = sly.Api()
```

### Get `workspace_id` from environment variables

```python
workspace_id = sly.env.workspace_id()
```

### Initialize `DestinationProject` widget

```python
destination = DestinationProject(
    workspace_id=workspace_id,
    project_type=sly.ProjectType.IMAGES,
)
```

### Create `Button`, `Text` widgets we will use in UI for demo

```python
button = Button()
text_project_id = Text()
text_project_name = Text()
text_dataset_id = Text()
text_dataset_name = Text()
```

### Create app layout

Prepare a layout for app using `Card` widget with the `content` parameter and place widget that we've just created in the `Container` widget.

```python

container = Container(
    widgets=[
        button,
        text_project_id,
        text_project_name,
        text_dataset_id,
        text_dataset_name,
    ]
)

card = Card(
    "Destination Project",
    content=Container([destination, container]),
)

layout = Container(widgets=[card])
```

### Create app using layout

Create an app object with layout parameter.

```python
app = sly.Application(layout=layout)
```

### Add functions to control widgets from code

```python
@button.click
def get_destination():
    text_project_id.text = f"project_id: {destination.get_selected_project_id()}"
    text_project_name.text = f"project_name: {destination.get_project_name()}"
    text_dataset_id.text = f"dataset_id: {destination.get_selected_dataset_id()}"
    text_dataset_name.text = f"dataset_name: {destination.get_dataset_name()}"
```
