Question
Answer and Explanation
Downloading a Superset dashboard and managing its permissions involves several key steps. Here’s a detailed explanation:
Downloading a Superset Dashboard
1. Exporting a Dashboard as JSON:
- Superset does not directly offer a "download" option for dashboards in a visual format like PDF. Instead, you typically export dashboards as a JSON (JavaScript Object Notation) file. This JSON file contains the dashboard's metadata, including charts, layouts, and configurations.
- To do this, navigate to the dashboard you wish to download in Superset.
- Look for an option such as "Export" or "Share" (depending on your Superset version) typically found in the dashboard's menu or action bar.
- Select the option to export as JSON. A file will be downloaded with a `.json` extension, which you can use to import the dashboard into another Superset instance.
2. Importing a Dashboard (Using JSON File):
- In the destination Superset instance, go to the "Dashboards" page.
- Look for an "Import" or "Upload" button/option which allows you to upload a JSON file.
- Select the downloaded JSON file, and Superset will re-create the dashboard based on the data in the JSON file. Note that the underlying datasets and databases must exist and be accessible.
Managing Dashboard Permissions
1. Superset’s Role-Based Access Control (RBAC):
- Superset uses RBAC to manage access to dashboards, charts, datasets, and other resources. User access is determined by the roles assigned to them.
- Superset has several built-in roles like `Admin`, `Alpha`, `Gamma`, and `Public`, with varying levels of access and privileges.
2. Assigning Roles to Users:
- Go to "Security" (or "Settings" -> "Users & Roles," depending on your Superset version) in the Superset user interface.
- Locate the user you wish to manage and click the "Edit" or "Permissions" option for that user.
- Assign the relevant roles to the user. For example, give `Gamma` role to regular users and `Admin` or `Alpha` roles for users needing more permissions.
3. Specific Dashboard Permissions:
- Permissions can also be managed at the resource level (for example, at the dashboard level) by going to a specific dashboard, and choosing the 'Edit' option for that particular dashboard. In that page, you will be able to choose which roles will have access to a specific dashboard.
- To give view or edit access to a specific dashboard, select the dashboard, then choose to manage permissions. This is often found in the dashboard settings or options and often it can be managed from the edit page of that dashboard.
- Choose whether you want to give access to certain roles. For instance, allow 'Gamma' role to view or edit a particular dashboard or leave this to 'admin' users only.
4. Using Custom Roles:
- For finer-grained control, you can define custom roles with specific permissions. This is done through the Superset admin panel, where you can create a new role and assign the relevant permission.
Code Example to Set Permissions (Illustrative):
Note that this part is more conceptual as Superset permissions are mainly managed through its interface and not through direct code unless you're using Superset's API.
Here is a conceptual example how you could use the Superset's API with Python code. In this case, we are using a Python library named 'requests'. Please note, that this is purely for illustrative purposes:
import requests
SUPERSERT_URL = "http://your-superset-url.com"
API_KEY = "your_api_key"
DASHBOARD_ID = 123
USER_ID = 456
ROLE_ID = 789
headers = {
"Authorization": f"Bearer {API_KEY}",
"Content-Type": "application/json"
}
# Example: Assigning a dashboard to a user with a role.
data = {
"user_id": USER_ID,
"dashboard_id": DASHBOARD_ID,
"role_id": ROLE_ID
}
response = requests.post(f"{SUPERSERT_URL}/api/v1/dashboard/{DASHBOARD_ID}/permission", json=data, headers=headers)
if response.status_code == 200:
print("Permissions updated successfully!")
else:
print(f"Error updating permissions: {response.status_code}, {response.text}")
Key Points:
- Always ensure that your databases and datasets are correctly configured before importing dashboards.
- Backup the dashboard configurations before making changes.
- Regularly review and manage user permissions to maintain security.
By following these steps, you can effectively download your Superset dashboards and manage permissions to control access to your visualizations.
