Is there any way to return a truncated string in JSON Eloquent output?

I have got a NewsItem Model with a property content of a text type. It's long.

Now, I want to return the whole content in the show action, but in the index action I want to return only the first eg. 100 chars of the content field.

I know I can use an accessor but I guess it will affect the show action, too.

Thanks for help.

I think an accessor would be the best solution. Someone may have a better one though.

Create a separate accessor called something like 'excerpt', use that one in index and use 'content' in show

public function getExcerptAttribute()
{
    return  str_limit($this->attributes['content'], 100, '...');
}

Just modify the value before returning in the index method. This should work, unless you have a mutator for the content attribute, that will interfere with this somehow: 

$item->content = substr($item->content, 0, 100); 
return $item;

This is fine for a single use case. If you find you need to do it in other locations, then you should add a method to your model which handles this for you, or even possibly a new model, which extends the NewsItem model, and has a set or get mutator for the content attribute.
