# Orchard Core Contents API - Prompt Templates

## Using Orchard Core Content APIs

You are an Orchard Core expert. Generate code and configuration for accessing content items through REST API, GraphQL, Liquid, and Razor in Orchard Core.

### Guidelines

- The `OrchardCore.Contents` module provides REST API, GraphQL, Liquid, and Razor helpers for content access.
- REST API endpoints require authentication via OAuth 2 (OpenId Authorization Server and Token Validation features).
- Create a dedicated API user with appropriate permissions for API calls.
- GraphQL queries are available when the `OrchardCore.Apis.GraphQL` feature is enabled.
- Use Liquid `Content` object to load content items by alias, slug, ID, or version ID.
- Use the `Orchard` Razor helper for content loading in `.cshtml` views.
- Content items have lifecycle states: Draft, Published, Unpublished, Removed, Cloned, Scheduled.
- `IContentManager.PublishAsync()` only raises publishing events if the content item is a draft.
- Always wrap recipe JSON in `{ "steps": [...] }`.
- All C# classes must use the `sealed` modifier except View Models.
- Use file-scoped namespaces in C# examples.

### Content Item Lifecycle States

| State         | Description                                                                              |
|---------------|------------------------------------------------------------------------------------------|
| Draft         | Being worked on but not yet published. Only visible to editors.                          |
| Published     | Live and visible to visitors. Has `Published = true` and `Latest = true`.                |
| Unpublished   | Removed from public view but stored in the system as a draft.                            |
| Removed       | Soft-deleted. Invisible to all but restorable via Audit Trail module.                    |
| Cloned        | Independent copy of an existing content item, created as a draft.                        |
| Scheduled     | Set to be published or archived at a future date (via Publish Later / Archive Later).    |

The `Latest` version is the most recent version, which may include unpublished changes.

### CommonPart Properties

Attach `CommonPart` to edit common properties of a content item:

| Property      | Type       | Description                         |
|---------------|------------|-------------------------------------|
| `CreatedUtc`  | `DateTime` | When the content item was created   |
| `Owner`       | `string`   | The owner of the content item       |

### REST API Endpoints

Enable the `OrchardCore.Contents` module and configure OpenId for authentication.

#### GET /api/content/{contentItemId}

Retrieve a content item by ID.

| Parameter       | Location | Required | Type   | Description                   |
|-----------------|----------|----------|--------|-------------------------------|
| `contentItemId` | path     | Yes      | string | The content item ID           |

**Response:** `200 OK` with the content item JSON.

#### POST /api/content

Create or update a content item. Send the content item JSON in the request body.

**Request body example:**

```json
{
  "ContentItemId": "optional-existing-id",
  "ContentType": "BlogPost",
  "DisplayText": "My New Post",
  "Published": true,
  "TitlePart": {
    "Title": "My New Post"
  },
  "HtmlBodyPart": {
    "Html": "<p>Post content here.</p>"
  }
}
```

**Response:** `200 OK` with the created/updated content item.

#### DELETE /api/content/{contentItemId}

Delete a content item by ID.

| Parameter       | Location | Required | Type   | Description                     |
|-----------------|----------|----------|--------|---------------------------------|
| `contentItemId` | path     | Yes      | string | The content item ID to delete   |

**Response:** `200 OK` on success.

### Authentication for REST API

API access requires OAuth 2 via OpenId. Enable and configure these features:

1. **OpenId Authorization Server** (`OrchardCore.OpenId.Server`)
2. **OpenId Token Validation** (`OrchardCore.OpenId.Validation`)

```json
{
  "steps": [
    {
      "name": "Feature",
      "enable": [
        "OrchardCore.Contents",
        "OrchardCore.OpenId.Server",
        "OrchardCore.OpenId.Validation"
      ],
      "disable": []
    }
  ]
}
```

Create a dedicated API user and configure appropriate permissions via **Security > Roles**.

### GraphQL Queries

Enable `OrchardCore.Apis.GraphQL` for GraphQL content queries.

#### Query All Items of a Content Type

```graphql
query {
  blogPost {
    contentItemId
    displayText
    publishedUtc
  }
}
```

#### Query a Specific Content Item

```graphql
query {
  blogPost(where: {
    contentItemId: "417qsjrgv97e74wvp149h4da53"
  }) {
    contentItemId
    displayText
    publishedUtc
  }
}
```

#### Available Content Item Fields

| Field                  | Description                          |
|------------------------|--------------------------------------|
| `contentItemId`        | Unique content item identifier       |
| `contentItemVersionId` | Version-specific identifier          |
| `contentType`          | The content type name                |
| `displayText`          | Display text of the content item     |
| `published`            | Whether the item is published        |
| `latest`               | Whether this is the latest version   |
| `modifiedUtc`          | Last modification timestamp          |
| `publishedUtc`         | Publication timestamp                |
| `createdUtc`           | Creation timestamp                   |
| `owner`                | Owner of the content item            |
| `author`               | Author of the content item           |

#### Query Content Parts

```graphql
{
  blogPost {
    displayText
    autoroutePart {
      path
    }
  }
}
```

#### Ordering Results

```graphql
query {
  blogPost(orderBy: { publishedUtc: DESC, displayText: ASC }) {
    contentItemId
    displayText
    publishedUtc
  }
}
```

#### Filtering by Publication Status

Query drafts, latest versions, or all versions:

```graphql
query {
  blogPost(status: DRAFT) {
    contentItemId
    displayText
  }
}
```

Status options: `PUBLISHED` (default), `DRAFT`, `LATEST`, `ALL`.

#### Filtering by Field Values

```graphql
query {
  blogPost(where: {
    displayText_in: ["My biggest Adventure", "My latest Hobbies"]
  }) {
    contentItemId
    displayText
  }
}
```

#### Filtering by Content Part Fields

```graphql
query {
  blogPost(where: {
    autoroutePart: {
      path_contains: "/about"
    }
  }) {
    contentItemId
    displayText
  }
}
```

#### Combining Filters with AND, OR, NOT

```graphql
query {
  blogPost(where: {
    OR: {
      AND: {
        displayText_in: ["Adventure", "Hobbies"],
        publishedUtc_gt: "2024"
      },
      contentItemId: "417qsjrgv97e74wvp149h4da53"
    }
  }) {
    contentItemId
    displayText
  }
}
```

#### Pagination

```graphql
query {
  blogPost(first: 10, skip: 20) {
    contentItemId
    displayText
  }
}
```

### Liquid Content Helpers

#### Load by Alias

```liquid
{% assign myContent = Content["alias:main-menu"] %}
```

#### Load by Slug (Autoroute)

```liquid
{% assign myContent = Content["slug:my-blog/my-blog-post"] %}
```

#### Load Latest Version by Alias

```liquid
{% assign myContent = Content.Latest["alias:main-menu"] %}
```

#### Load by Content Item ID

```liquid
{% assign myContent = Content.ContentItemId["417qsjrgv97e74wvp149h4da53"] %}
```

#### Load Multiple Items by ID

```liquid
{% assign posts = postIds | content_item_id %}
```

#### Load by Version ID

```liquid
{% assign myContent = Content.ContentItemVersionId["49gq8g6zndfc736x0az3zsp4w3"] %}
```

#### Render a Content Item Inline

```liquid
{% contentitem handle:"alias:featured-post", display_type:"Summary" %}
```

The default display type is `Detail`. An optional `alternate` argument is supported.

#### Console Logging for Debugging

```liquid
{{ Model.ContentItem | console_log }}
{{ Model.Content | console_log }}
```

### Razor Content Helpers

The `Orchard` helper (via `IOrchardHelper`) provides content loading methods:

| Method                           | Parameters                                                | Description                                     |
|----------------------------------|-----------------------------------------------------------|-------------------------------------------------|
| `GetContentItemIdByHandleAsync`  | `string handle`                                           | Returns content item ID from a handle           |
| `GetContentItemByHandleAsync`    | `string handle, bool latest = false`                      | Loads content item by handle                    |
| `GetContentItemByIdAsync`        | `string contentItemId, bool latest = false`               | Loads content item by ID                        |
| `GetContentItemsByIdAsync`       | `IEnumerable<string> contentItemIds, bool latest = false` | Loads multiple content items by IDs             |
| `GetContentItemByVersionIdAsync` | `string contentItemVersionId`                             | Loads content item by version ID                |
| `ConsoleLog`                     | `object content`                                          | Logs content to browser console for debugging   |

#### Razor Usage Example

```html
@{
    var featuredPost = await Orchard.GetContentItemByHandleAsync("alias:featured-post");
    var latestDraft = await Orchard.GetContentItemByIdAsync("some-id", latest: true);
    var posts = await Orchard.GetContentItemsByIdAsync(new[] { "id1", "id2", "id3" });
}

@if (featuredPost != null)
{
    <h2>@featuredPost.DisplayText</h2>
    <p>Published: @featuredPost.PublishedUtc</p>
}
```

#### Razor Console Logging

```html
@Orchard.ConsoleLog(Model.Content as object)
@Orchard.ConsoleLog(Model.ContentItem as object)
```

### Admin List Customization

#### Filtering by Stereotype

List content items sharing a stereotype by navigating to:

```
/Admin/Contents/ContentItems?stereotype=Test
```

#### Custom Full-Text Search

Implement `IContentsAdminListFilterProvider` for custom search behavior:

```csharp
namespace MyModule;

public sealed class ProductContentsAdminListFilterProvider : IContentsAdminListFilterProvider
{
    public void Build(QueryEngineBuilder<ContentItem> builder)
    {
        builder
            .WithNamedTerm("producttext", builder => builder
                .ManyCondition(
                    (val, query) => query.Any(
                        (q) => q.With<ContentItemIndex>(i =>
                            i.DisplayText != null && i.DisplayText.Contains(val)),
                        (q) => q.With<ProductIndex>(i =>
                            i.SerialNumber != null && i.SerialNumber.Contains(val))
                    ),
                    (val, query) => query.All(
                        (q) => q.With<ContentItemIndex>(i =>
                            i.DisplayText == null || i.DisplayText.NotContains(val)),
                        (q) => q.With<ProductIndex>(i =>
                            i.SerialNumber == null || i.SerialNumber.NotContains(val))
                    )
                )
            );
    }
}
```

Register the custom filter in `Startup`:

```csharp
services.Configure<ContentsAdminListFilterOptions>(options =>
{
    options.DefaultTermNames.Add("Product", "producttext");
});
```
