Saving hasMany through data
I don't know that you are saving post comments using form and also i am not sure about that which version of cakephp you are using but my solution is for cakephp2.x .If you wanna save data using form then create your post form like this and for saving has many mentioned related model name in fields.For example here you want save related comment of post see the code below
<?php echo $this->Form->create('Post'); ?>
<?php echo $this->Form->input('Post.title'); ?>
<?php echo $this->Form->input('Post.content'); ?>
<?php echo $this->Form->input('Comment.comment'); ?>
<button type="submit">Save</button>
<?php echo $this->Form->end(); ?>
Using this form u will get the request data like this.
Array
(
[0] => Array
(
[Post] => Array
(
[title] => It is a post title
[content] => you post content
)
[Comment] => Array
(
[comment] => this is my post comment
)
)
)
or if you wanna save data with out using form then u have to create data like this and also see CakePhp Save hasmany
