# Actions

In this section, you will update the "environment template" to use an **action**. The action will be configured to control the logic defined within the Python code of a function workflow handler.

* * *

## Step 1: Update Workflow Handler

In this step, you will update the existing Workflow Handler used in the Introductory Exercise. You will update the WorkflowHandler function code logic to handle different action types.

- In your project, navigate to **Environments -> Workflow Handlers**
- Click on the name of the previously created workflow handler
- Navigate to **Function**
- Replace the function source code with the below code

```python
   from typing import Dict, Any
   from logging import Logger

def handle(logger: Logger, request: Dict[str, Any]) -> Dict[str, Any]:
       logger.info(f"Inside function handler, request: {request}", extra={"request": request})

action = request.get("action")

if action == "deploy":
           logger.info("hello world")
           return {
               "output": "hello world",
               "action": action
           }

elif action == "retry":
           logger.info("hello again")
           return {
               "output": "hello again",
               "action": action
           }

else:
           logger.info("unknown action")
           return {
               "output": "unknown action",
               "action": action
           }
   ```

- Click **Save**

## Step 2: Update Environment Template

In this step, you will update the existing Environment Template to include an Action. The Action will use the same workflow handler, however, now the logic will be controlled by the Action the user selects.

- In your project, navigate to **Environments -> Environment Templates**
- Click on the name of the environment template
- Edit the template
- Navigate to **Actions**
- Click **\+ Actions**
- Enter the name **retry**. Note, this name is what will be passed as a variable to the workflow handler to determine the logic used.
- Select **Workflows** for the Type
- Expand the **Custom Providers** section
- Click **\+ Task**
- Enter a name for the task
- Select the previously modified workflow handler for the Driver Name
- Click **Save & Continue**

- Click **Save**

Next, we will create an input variable that will pass the action value to the workflow handler.

- Navigate to **Input Variables**
- Click **\+ Variable**
- Enter a name for the variable
- Select **Not Allowed** for the Override
- Select **Expressions** for the Value Type
- Enter the following code for the Default Value

```python
   ## script begin ##
   def eval(**ctx):
     action_name = ctx["trigger"]["payload"].get("action_name")
     if action_name:
       return action_name
     return ctx["trigger"]["payload"].get("action")
   ## script end ##
   ```

- Click **Save**
- Select **No, Exit**

**Note:** In the case you want to use a selector to refine where this variable is passed to, you can use **environment.action..** to pass the action name to the action

- Click **Save as Draft**

* * *

## Step 3: Run Action

In this step, we will create a new environment using the recently updated environment template. Once the environment is created, we will run the **retry** action on the environment to see the output that should be displayed from this action.

- In your project, navigate to **Environments -> Environments**
- Click **Launch** on the environment template card
- Enter a name for the environment
- Click **Save & Deploy**

After the environment is created, you will see the results sections shows the "deploy" action and the output "hello world".

Next, you will run the previously created **retry** action on the environment to produce a different output.

- Click **Show** in the Actions section
- Select the previously created **retry** action
- Click **Open Action**
- Click **Execute Action**

Once the action has finished running:

- Click **Show** in the Activities section
- Expand the first section to see the action outputs

You will see the action is not "retry" and the output is "hello again". The output is different as the logic in the workflow handler was set to return this output value if the action was equal to "retry".

## Recap

In this part, you created an **action** on your environment template. The action was configured to trigger different logic within the workflow handler.
