## Overview

### What are Wrappers?

Wrappers are pre-built functions that encapsulate common TrustCafé API operations. They:

- **Simplify usage**: Less boilerplate code
- **Handle payload preparation**: Automatically structure requests
- **Prevent errors**: Built-in validation and defaults
- **Self-documenting**: Clear parameter names and descriptions

### When to Use Wrappers

**Use Wrappers for:**
- Creating and managing content (posts, comments)
- Standard operations with predictable inputs
- Reducing code complexity
- Frequently used patterns

**Use Jobs or Custom Requests when:**
- More control is needed
- Custom parameter combinations
- Operations not covered by wrappers
- Uncommon workflows

### Quick Example

```python
# Using a wrapper (RECOMMENDED)
from trustcafeapiwrapper.wrappers.post.create_post import create_post

API.wrapped(create_post(
    "This is my post content",
    parent_path="/music"
))

# Using a job (for custom control)
API.run_job('post.create', {
    "postText": "Different content",
    "parent": {
        "pk": "parents-key",
        "sk": "parents-key"
    }
})
```

## Post Wrappers

### create_post()

Creates a new post with simplified parameters.

```python
from trustcafeapiwrapper.wrappers.post.create_post import create_post

API.wrapped(create_post(
    post_text="Post content here",
    parent_path="/branch-name",
    blur_label=None,
    card_url=None,
    collaborative=False
))
```

**Parameters:**

| Parameter | Type | Default | Description |
|-----------|------|---------|-------------|
| `post_text` | str | **Required** | The text content of the post |
| `parent_path` | str | `"/"` | Branch path where the post will be created |
| `blur_label` | str | `None` | Optional label for blurring content |
| `card_url` | str | `None` | Optional URL for card preview |
| `collaborative` | bool | `False` | Enable collaborative editing |

**Returns:** dict - Job execution result, contains success information

**Example - Basic Post:**

```python
from trustcafeapiwrapper.wrappers.post.create_post import create_post

API.handle_token()

API.wrapped(create_post(
    "Welcome to TrustCafé!",
    parent_path="/"
))
```

**Example - Post in a Specific Branch:**

```python
API.wrapped(create_post(
    "Music discussion thread",
    parent_path="/music",
    blur_label=None,
    card_url=None,
    collaborative=False
))
```

**Example - Blurred Post:**

```python
API.wrapped(create_post(
    "Sensitive information",
    parent_path="/",
    blur_label="secret",  # Will blur until labeled
    card_url=None,
    collaborative=False
))
```

**Example - Collaborative Post:**

```python
API.wrapped(create_post(
    "Research paper draft - collaborative editing",
    parent_path="/research",
    blur_label=None,
    card_url=None,
    collaborative=True  # Enables real-time collaboration
))
```

Example of performing multi-step integration with create_post and a linked resource:
```python
# Create post
created = API.wrapped(create_post("Paper title / author", parent_path="/research"))

# If response includes pk/sk, attach a linked item (structure depends on TrustCafé's link feature)
API.run_job('some.link.create', {
    "fromPK": "paper",
    "fromSK": created.get('pk'),
    "toPK": "external-source",
    "toSK": created.get('sk')
})
```

### update_post()

Updates an existing post.

```python
from trustcafeapiwrapper.wrappers.post.update_post import update_post

API.wrapped(update_post(
    post_text="New post content",
    parent_path="/branch-name"
))
```

**Parameters:**

| Parameter | Type | Default | Description |
|-----------|------|---------|-------------|
| `post_text` | str | **Required** | The new text for the post |
| `post_path` | str | `None` | The path of the post to update |
| `parent_path` | str | `"/"` | The parent path for the post |
| `post_key` | dict | `None` | A dictionary containing `pk` and `sk` of the post |
| `blur_label` | str | `None` | Optional blur label for the post |
| `card_url` | str | `None` | Optional card URL for the post |
| `collaborative` | bool | `False` | Whether the post is collaborative |

**Returns:** dict - Updated post data

**Note:** You must provide either:
- Both `post_path` and `parent_path`, or
- The `post_key` dict with `pk` and `sk`

**Example - Update Text:**

```python
from trustcafeapiwrapper.wrappers.post.update_post import update_post

API.handle_token()

API.wrapped(update_post(
    post_text="Updated content here",
    parent_path="/music"
))
```

**Example - Update with Optional Fields:**

```python
API.wrapped(update_post(
    post_text="Updated with new card",
    parent_path="/music",
    card_url="https://example.com/resource"
))
```

**Example - Update Using post_key:**

```python
API.wrapped(update_post(
    post_text="Updated via key",
    post_key={
        "pk": "post-id",
        "sk": "post-id"
    }
))
```

**Example - Update Blur Label:**

```python
API.wrapped(update_post(
    post_text="Sensitive content",
    parent_path="/",
    blur_label="sensitive"
))
```

See update_post.py for full mapping of updated fields to the server payload.

## Comment Wrappers

### create_comment()

Creates a new comment on a post.

```python
from trustcafeapiwrapper.wrappers.comment.create_comment import create_comment

API.wrapped(create_comment(
    comment_text="This is a comment"
))
```

**Parameters:**

| Parameter | Type | Default | Description |

- Both `post_slug` and `parent_path`

**Example - Basic Comment:**

```python
from trustcafeapiwrapper.wrappers.comment.create_comment import create_comment

API.handle_token()

API.wrapped(create_comment(
    "Great post! I really enjoyed reading it."
))
```

**Example - Comment on a Post by Slug:**

```python
from trustcafeapiwrapper.wrappers.comment.create_comment import create_comment

API.handle_token()

API.wrapped(create_comment(
    "I agree with your point about this.",
    post_slug="target-post-slug",
    parent_path="/branch-name"
))
```

**Example - Comment on a Post by post_key:**

```python
API.wrapped(create_comment(
    "Let's work on this together!",
    post_key={
        "pk": "post-id",
        "sk": "post-id"
    }
))
```

**Example - Collaborative Comment:**

```python
from trustcafeapiwrapper.wrappers.comment.create_comment import create_comment

API.wrapped(create_comment(
    "Let's work on this together!",
    post_slug="current-post-slug",
    parent_path="/research"
))
```

## Wrappers Best Practices

### 1. Provide Context in Parent Paths

**Good - Explicit paths:**

```python
API.wrapped(create_post(
    "Content",
    parent_path="/music/discussion"  # Clear and specific
))
```

**Bad - Empty paths:**

```python
API.wrapped(create_post(
    "Content",
    parent_path="/"  # Default root - less clear intention
))
```

### 2. Handle Phone Numbers in Content

When phone numbers appear in text, leave them as-is. The API wraps the input string, so `555-1234` stays `555-1234`. No HTML is added.

### 3. Path Normalization

Paths are used directly without extra normalization:

```python
# Use with leading slash
API.wrapped(create_post(
    "Content",
    parent_path="/music"
))

# Or without (both should work)
API.wrapped(create_post(
    "Content",
    parent_path="music"
))
```

### 4. Validate Parent Exists

It's good practice to verify the parent path exists:

```python
# Check if branch exists
branches = API.run_job('branch.listbyname', "music")

if branches.get('Items'):
    # Branch exists, proceed with post
    API.wrapped(create_post(
        "Content",
        parent_path="/music"
    ))
else:
    print("Branch 'music' does not exist")
```

### 5. Handle Responses

```python
from trustcafeapiwrapper.wrappers.post.create_post import create_post

response = API.wrapped(create_post(
    "My post",
    parent_path="/music"
))

# Check for success
if response and 'success' in response:
    print("Post created successfully!")
    print(f"Post ID: {response.get('pk')}")
else:
    print("Failed to create post")
    print(f"Error: {response.get('error')}")
```

### 6. Error Handling

```python
from trustcafeapiwrapper.wrappers.post.create_post import create_post
import logging

logger = logging.getLogger(__name__)

try:
    API.handle_token()  # Ensure authenticated
    API.wrapped(create_post(
        "Post content",
        parent_path="/music"
    ))
    logger.info("Post created successfully")
except Exception as e:
    logger.error(f"Failed to create post: {e}")
    # Handle error - maybe retry, notify admin, etc.
```

## Wrapper vs Job

| Feature | Wrappers | Jobs |
|---------|----------|------|
| **Simplicity** | ⭐⭐⭐⭐⭐ | ⭐⭐ |
| **Flexibility** | ⭐⭐⭐ | ⭐⭐⭐⭐⭐ |
| **Default Values** | ✅ Yes | ❌ No |
| **Parameter Validation** | ✅ Yes | ❌ No |
| **Common Operations** | ✅ Many | ❌ None |
| **Custom Operations** | ❌ No | ✅ Yes |
| **Learning Curve** | Low | High |

### Replacement Examples

**Example 1: Create Post**

```python
# Wrapper - Simple
API.wrapped(create_post(
    "Content",
    parent_path="/music"
))

# Job - More complex
API.run_job('post.create', {
    "postText": "Content",
    "parent": {
        "pk": "encode(parent_path)",
        "sk": "encode(parent_path)"
    }
})
```

**Example 2: Update Post**

```python
# Wrapper
API.wrapped(update_post(
    post_text="New content",
    parent_path="/music"
))

# Job
API.run_job('post.update', {
    "pk": "post-id",
    "sk": "post-id",
    "newPostText": "New content"
})
```

**Example 3: Create Comment**

```python
# Wrapper
API.wrapped(create_comment(
    "My comment",
    post_slug="post-id",
    parent_path="/branch"
))

# Job
API.run_job('comment.create', {
    "commentText": "My comment",
    "parent": {
        "pk": "post-id",
        "sk": "post-id"
    }
})
```

### When to Use Each

**Use Wrappers When:**
- Common operation (create/update post/comment)
- Multiple optional parameters
- Want concise, readable code
- Acceptable default behavior

**Use Jobs When:**
- Rarely used operation
- Very specific parameter combinations
- Custom job names unsupported by wrappers
- Need maximum flexibility

## Creating Custom Wrappers

You can create your own wrappers for repeated operations:

```python
# Custom post wrapper
def create_in_branch(API, branch: str, content: str, create_card: bool = False):
    """
    Helper wrapper for creating posts in specific branches.

    Args:
        API: The APIClient instance
        branch: Branch name (e.g., "music", "science")
        content: Post content
        create_card: Whether to create a card URL

    Returns:
        dict: API response
    """
    card_url = "https://example.com/card" if create_card else None

    from trustcafeapiwrapper.wrappers.post.create_post import create_post

    return API.wrapped(create_post(
        content,
        parent_path=f"/{branch}",
        card_url=card_url
    ))

# Usage
API.handle_token()
result = create_in_branch(API, "music", "New music discussion")

# Or with card
result = create_in_branch(API, "science", "Research paper abstract", create_card=True)
```

---

## Summary

Wrappers provide a convenient, safe way to perform common operations with the TrustCafé API. For most use cases, wrappers reduce boilerplate and prevent configuration errors. However, jobs offer greater flexibility when standard wrappers don't meet your needs.

**Choose wisely:**
- Wrappers for standard operations and simplicity
- Jobs for custom operations and maximum control
