Get only one media

[pet1330]

I think what you're looking to do is only fetch from the database a single Media model per Post, rather than fetching all attached Media and iterating through the collection to filter out all but one. In which case I think you will need to use the query builder to do something like:

$PostsWithOneMedia = Post::with(['media' => function($q) {
        $q->latest()->limit(1);
    }])->get();

Or for a specific tag

$tag = "uploaded";

$PostsWithOneMedia = Post::with(['media' => function($q) use ($tag) {
        $q->wherePivot('tag', $tag)->latest()->limit(1);
    }])->get();

Hi @borisdamevin,

If I understand correctly, you have a posts collection, with media loaded and want to access a single media record attached to any one of the posts at a given tag?

If all posts have media attached to that tag, then $posts->first()->firstMedia($tag) will do. Otherwise you would need to filter down the posts to only include ones that do, either by adding conditions to the Post query or filtering the resulting collection first.

$media = Post::whereHasMedia($tag)  // restrict to results with that media
->withMedia($tag) // eager load the media at that tag
->first() //only load one post result
->firstMedia($tag); //get the first media record attached to this post

or

$posts = Posts::withMedia()->get(); // load all posts
$media = $posts->filter(function($post) use ($tag)  {
    return $post->hasMedia($tag); //restrict to those that have media for that tag
})->firstMedia($tag);

Yes.

But firstMedia() work only for get media in one post, not for a collection of posts.

The best way will not to create a scope for get only the first media in collection ?

Sorry, the second example above is missing a call to first() on the collection. It should be $posts->filter(...)->first()->firstMedia($tag).

[borisdamevin]

The filter don't work. He get the same media for all posts.

You don't have an idea for filter $posts = Posts::withMedia()->get(); directly on the select for get one media and not overload the database?

Hi @borisdamevin, I not clear what your intention is here. From your description it sounds like you are trying to get a single media from a collection of mediables, but if that is not the case, can you be more descriptive of your needs?

Are you trying to create a collection with one media record for each post?

[borisdamevin]

Hi,

Yes I try to get only one media on each post.

[frasmage]

Ok, that wasn't clear from your initial message. This isn't really a Mediable concern, but with Laravel collection handling.

$media = $posts
->filter(...) //as above, use if you want to exclude posts that do not have media at that tag
->map(function($post) use ($tag){
    return $post->firstMedia($tag);
}

I finally find the good with your help.

$posts = Post::with(['media' => function($q){
    $q->wherePivot('tag', 'thumbnail')->wherePivot('order', '1');
}])->get();

Thank for your help :).

Sorry if my request was not clear.
