Elsa 3.1.3 Create custom role activity code?

[glime-ai[bot]]

To create a custom role activity in Elsa 3.1.3, you would need to follow the general steps for creating custom activities in Elsa, as outlined in the Elsa documentation. Here's a simplified example of how you might create a custom activity that checks if a user has a specific role:

1. Create a class that inherits from CodeActivity or another appropriate base class if you need more complex behavior.
2. Define any inputs, outputs, or properties that your activity requires.
3. Implement the Execute method to contain the logic for your role check.
4. Register your custom activity with the Elsa workflow runtime.

Here's a basic example in C#:

using Elsa.ActivityResults;
using Elsa.Attributes;
using Elsa.Services;
using Elsa.Services.Models;

namespace MyElsaExtensions.Activities
{
    [Activity(
        Category = "User",
        DisplayName = "Check User Role",
        Description = "Checks if the user has the specified role",
        Outcomes = new[] { "True", "False" }
    )]
    public class CheckUserRole : CodeActivity
    {
        [ActivityInput(Hint = "Enter the role to check.")]
        public string Role { get; set; }

        protected override IActivityExecutionResult OnExecute(ActivityExecutionContext context)
        {
            // Replace this with your actual role-checking logic.
            bool hasRole = CheckUserRoleLogic(context.User, Role);

            // Return an outcome based on whether the user has the role.
            return Outcome(hasRole ? "True" : "False");
        }

        private bool CheckUserRoleLogic(IUser user, string role)
        {
            // Implement your role-checking logic here.
            // This could involve checking against a database or an identity management system.
            return user.Roles.Contains(role);
        }
    }
}

To register this activity, you would add it to the Elsa services configuration in your Startup.cs or Program.cs:

services.AddElsa(elsa => elsa.AddActivity<CheckUserRole>());

Please note that the CheckUserRoleLogic method is a placeholder where you would implement the actual logic to check if a user has a role. This might involve interacting with a user management system or database.

Remember to replace the placeholder logic with your actual role-checking implementation and adjust the activity's properties and outcomes as needed for your specific use case.
