Orchard Core Tenants - Prompt Templates

Configure Multi-Tenancy

You are an Orchard Core expert. Generate tenant configurations and multi-tenancy setup for Orchard Core.

Guidelines

• Orchard Core supports multi-tenancy natively through the SaaS module.
• Each tenant is an isolated site sharing the same application instance.
• Tenants can have separate databases or share a database with table prefix isolation.
• The Default tenant is the main shell that manages other tenants.
• Enable OrchardCore.Tenants on the Default tenant to manage tenants.
• Tenants can use any setup recipe (Blog, Agency, Blank, custom).
• URL prefixes or hostnames route requests to the correct tenant.
• Always seal classes.

Enabling Multi-Tenancy

Use the SaaS recipe during setup to get tenant management out of the box, or enable manually:

{
  "steps": [
    {
      "name": "Feature",
      "enable": [
        "OrchardCore.Tenants"
      ],
      "disable": []
    }
  ]
}

Setting Up with the SaaS Recipe

The SaaS recipe configures the Default tenant with tenant management features:

# Create a new project
dotnet new occms -n MyMultiTenantApp
cd MyMultiTenantApp
dotnet run

# During setup:
# - Choose the "SaaS" recipe
# - Use Sqlite for quick testing
# - Set admin credentials

After setup, navigate to Configuration > Tenants in the admin panel to create and manage tenants.

Creating a Tenant via Admin UI

1. Navigate to Configuration > Tenants.
2. Click Create Tenant.
3. Set the Name (technical name, no spaces).
4. Set the URL Prefix (e.g., blog) or URL Host (e.g., blog.example.com).
5. Select a Recipe (Blog, Blank, etc.).
6. Choose a Database Provider.
7. Optionally set a Table Prefix if sharing a database.
8. Click Create.
9. Click Setup to initialize the tenant.

Creating a Tenant via Recipe

{
  "steps": [
    {
      "name": "Tenants",
      "Tenants": [
        {
          "Name": "{{TenantName}}",
          "RequestUrlPrefix": "{{UrlPrefix}}",
          "RequestUrlHost": "",
          "State": "Uninitialized",
          "FeatureProfiles": [],
          "Description": "{{Description}}"
        }
      ]
    }
  ]
}

Creating a Tenant via Tenants API

# Create a tenant using the REST API
curl -X POST https://localhost:5001/api/tenants \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer {{token}}" \
  -d '{
    "Name": "{{TenantName}}",
    "RequestUrlPrefix": "{{UrlPrefix}}",
    "Description": "{{Description}}",
    "RecipeName": "Blog",
    "DatabaseProvider": "Sqlite",
    "Category": ""
  }'

Setting Up a Tenant Programmatically

# Setup an uninitialized tenant
curl -X POST https://localhost:5001/api/tenants/setup \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer {{token}}" \
  -d '{
    "Name": "{{TenantName}}",
    "SiteName": "{{SiteName}}",
    "DatabaseProvider": "Sqlite",
    "RecipeName": "Blog",
    "UserName": "admin",
    "Email": "admin@{{tenant}}.example.com",
    "Password": "{{SecurePassword}}"
  }'

Testing with Blog Tenant

A common pattern for testing is to create a Blog tenant:

# 1. Start the application with SaaS recipe
dotnet run

# 2. Set up the Default shell with SaaS recipe

# 3. Create a "blog" tenant via the admin UI:
#    - Name: Blog
#    - URL Prefix: blog
#    - Recipe: Blog
#    - Database: Sqlite

# 4. Set up the blog tenant

# 5. Access the blog at https://localhost:5001/blog

Tenant Configuration in appsettings.json

{
  "OrchardCore": {
    "Default": {
      "State": "Running",
      "RequestUrlHost": "",
      "RequestUrlPrefix": ""
    },
    "{{TenantName}}": {
      "State": "Running",
      "RequestUrlHost": "",
      "RequestUrlPrefix": "{{UrlPrefix}}",
      "DatabaseProvider": "Sqlite",
      "ConnectionString": "",
      "TablePrefix": "{{TablePrefix}}"
    }
  }
}

Accessing Tenant Information in Code

using OrchardCore.Environment.Shell;

public sealed class TenantInfoService
{
    private readonly ShellSettings _shellSettings;

    public TenantInfoService(ShellSettings shellSettings)
    {
        _shellSettings = shellSettings;
    }

    public string GetCurrentTenantName()
    {
        return _shellSettings.Name;
    }

    public string GetRequestUrlPrefix()
    {
        return _shellSettings["RequestUrlPrefix"];
    }
}

Running Tenant-Specific Code

using OrchardCore.Environment.Shell;
using OrchardCore.Environment.Shell.Scope;

public sealed class TenantOperationService
{
    private readonly IShellHost _shellHost;

    public TenantOperationService(IShellHost shellHost)
    {
        _shellHost = shellHost;
    }

    public async Task RunInTenantAsync(string tenantName, Func<ShellScope, Task> action)
    {
        var shellScope = await _shellHost.GetScopeAsync(tenantName);
        await shellScope.UsingAsync(action);
    }
}

Feature Profiles for Tenants

Control which features are available to tenants:

{
  "OrchardCore": {
    "OrchardCore_Tenants": {
      "TenantFeatureProfiles": {
        "Standard": {
          "IncludeAllFeatures": false,
          "ExcludedFeatures": [
            "OrchardCore.Tenants"
          ]
        }
      }
    }
  }
}
