So I think your are doing something wrong in your controller. What do you send back after the post? Just one comment or all the comments?

Ajax returns entire page
I'm creating a social network site using Laravel. I have a page that load all the posts created by users the currentUser follows. I have a comment section on each post. I'm using ajax to post the comments.
Here is my code.
Here is the view of the comment-box. It contains a section where I loop through each comment and display them. At the end is the type field so a user can post a new comment:
<div class="comment-box-container ajax-refresh">
<div class="comment-box">
@if ($type->comments)
@foreach ($type->comments as $comment)
<div class="user-comment-box">
<div class="user-comment">
<p class="comment">
<!-- starts off with users name in blue followed by their comment-->
<span class="tag-user"><a href="{{ route('profile', $comment->owner->id) }}">{{ $comment->owner->first_name }} {{ $comment->owner->last_name }}</a> </span>{{ $comment->body }}
</p>
<!-- Show when the user posted comments-->
<div class="com-details">
<div class="com-time-container">
{{ $comment->created_at->diffForHumans() }} ·
</div>
</div>
</div><!--user-comment end-->
</div><!--user-comment-box end-->
@endforeach
@endif
<!--type box-->
<div class="type-comment">
<div class="type-box">
{{ Form::open(['data-remote', 'route' => ['commentPost', $id], 'class' => 'comments_create-form']) }}
{{ Form::hidden('user_id', $currentUser->id) }}
{{ Form::hidden($idType, $id) }}
{{--{{ Form::hidden('user_id', $currentUser->id) }}--}}
{{ Form::textarea('body', null, ['class' =>'type-box d-light-solid-bg', 'placeholder' => 'Write a comment...', 'rows' => '1']) }}
{{ Form::close() }}
</div><!--type-box end-->
</div><!--type-comment-->
</div><!--comment-box end-->
The user submit the form for the comment type box by pressing the "enter/return" key. Here is the JS for that
<script>
$(document).on('keydown', '.comments_create-form', function(e) {
if (e.keyCode == 13) {
e.preventDefault();
$(this).submit();
}
});
</script>
Here is my Ajax
(function(){
$(document).on('submit', 'form[data-remote]', function(e){
e.preventDefault();
var form = $(this)
var target = form.closest('div.ajax-refresh');
var method = form.find('input[name="_method"]').val() || 'POST';
var url = form.prop('action');
$.ajax({
type: method,
url: url,
data: form.serialize(),
success: function(data) {
var tmp = $('<div>');
tmp.html(data);
target.html( tmp.find('.ajax-refresh').html() );
target.find('.type-box').html( tmp.find('.type-box').html() );
tmp.destroy();
}
});
});
})();
When I post a comment on the first post it all works fine. However, when I post a comment on the second, third, fourth etc it only displays the comments from the first post. I have to manually refresh the page, then the correct comments will display.
I'll try to illustrate this problem with images.
Starting fresh, I can easily submit 2 comments on POST 1 http://s27.postimg.org/6ej76hunn/comment1.jpg
When I scroll down to Post 2, I see it already has a comment, I will submit a new comment http://s23.postimg.org/x65ui2ryz/comment_2.jpg
HERE'S THE PROBLEM: When I submit the comment on POST 2, the comments that were in POST 2 disappears, and are replaced by the comments from POST 1. http://s30.postimg.org/ugl08oz01/comment_3.jpg
The back end still worked, because when I reload the page everything is the way it should be http://s9.postimg.org/w51fgyzen/comment_4.jpg
When I check the console Ajax is returning the entire page. http://postimg.org/image/dec9y6rb5/ http://s11.postimg.org/465iq8mub/console2.png
I'm completely stuck. Does anyone know why this is happening and how to fix it?

@blackbird Here is my NewsfeedController that is loading the page with the posts:
public function index()
{
// load posts into the view.
$posts = $this->postRepository->getFeedForUser(Auth::user());
return View::make('newsfeed', compact('posts'));
}
The getFeedForUsers is this:
public function getFeedForUser(User $user)
{
// get a list of all the ids the user follows
$userIds = $user->followedUsers()->lists('followed_id');
// add in the current users posts as well
$userIds[] = $user->id;
// Resource is the posts
return Resource::with('messages', 'media', 'user', 'videos', 'comments', 'locations')->whereIn('user_id', $userIds)->latest()->get();
}
That Resource model has the relationship for the comments. it looks like this:
class Resource extends Eloquent {
public function comments()
{
return $this->hasMany('Duuer\Comments\Comment');
}
}
The route for saving a comment to the DB looks like this:
Route::post('post/{id}/comment', ['as' => 'commentPost', 'uses' => 'CommentsController@postComment']);
The CommentsController looks like this:
class CommentsController extends \BaseController {
use CommanderTrait;
/**
* Leave a new comment
* @return Response
*/
public function postComment()
{
extract(Input::only('user_id', 'resource_id', 'body'));
$this->execute(new PostCommentCommand($user_id, $resource_id, $body));
return Redirect::back();
}
public function deleteComment()
{
$comment = new Comment;
$user = Auth::user();
$id = Input::only('id');
$comment->where('user_id', $user->id)->where('id', $id)->first()->delete();
return Redirect::back();
}
}
I'm using a command bus, so my handler class looks like this:
public function handle($command)
{
$comment = $this->postRepository->leaveComment($command->user_id, $command->resource_id, $command->body);
return $comment;
}
That leaveComment() method looks like this:
public function leaveComment($user_id, $resource_id, $body)
{
$comment = Comment::leavePostComment($resource_id, $body);
User::findOrFail($user_id)->comments()->save($comment);
return $comment;
}
The leavePostComment() method in the Comment model looks like this:
public static function leavePostComment($resource_id, $body)
{
return new static([
'resource_id' => $resource_id,
'body' => $body
]);
}

@blackbird Any idea what I can do? From what I understand I'm sending all comments when I load the view with my NewsfeedController and I'm redirecting back with my CommentsController.
(I'm very new at this stuff)
