32

33

34
|
|
|
* When this component is attached you can render entity's comments using the |
35
|
|
|
* CommentHelper: |
36
|
|
|
* |
37
|
|
|
* ```php |
38
|
|
|
* // in any view: |
39
|
|
|
* $this->Comment->config('visibility', 1); |
40
|
|
|
* $this->Comment->render($entity); |
41

|
|
* // in any controller |
43
|

|
* $this->Comment->config('visibility', 1); |
44
|
|
|
* ``` |
45
|
|
|
* |
46
|
|
|
* You can set `visibility` using this component at controller side, or using |
47
|
|
|
* CommentHelper as example above, accepted values are: |
48
|
|
|
* |
49
|
|
|
* - 0: Closed; can't post new comments nor read existing ones. (by default) |
50

|
|
* - 1: Read & Write; can post new comments and read existing ones. |
51
|
|
|
