So as I write at title I need to get all users who post offer to an admin user article...
So I write:
public function userbase()
{
return Offer::select('users.*')
->where('users.admin', 9)
->join('articles','articles.id','=','offers.article_id')
->join('users','users.id','=','articles.user_id')
->where('articles.user_id', Auth::user()->id)
->orderBy('offers.created_at', 'desc')
->groupBy('users.id')
->get();
}
but I get just [] (which is not true) ...
I also try:
public function userbase()
{
$user_ids = Article::where('user_id', Auth::id())
->join('offers')->on('offers.article_id', '=', 'articles.id')
->join('users')->on('offers.user_id', '=', 'users.id')
->select('users.id')
->distinct()
->get();
$users = User::whereIn('id', $user_ids);
return $users;
}
but I get:
Missing argument 2 for Illuminate\Database\Query\Builder::join()
attempt was:
public function userbase() { $articles = Auth::user()->articles()->get(); foreach ($articles as $article) {
$offers = Offer::where('article_id', $article['id'])->orderBy('created_at', 'desc')->get();
}
foreach ($offers as $offer) {
$users = User::where('id', $offer['user_id'])->orderBy('created_at', 'desc')->get();
}
return $users;
}
but offcource dont work...
Now I really dont know what to do next... PLEASE HELP...
also my MODEL:
Article:
public function offers() {
return $this->hasMany('App\Offer');
}
Offer:
public function user() {
return $this->belongsTo('App\User');
}
public function article() {
return $this->belongsTo('App\Article');
}
So how I can get users who post offer to other user(admin) article...
Try to put this function in the User model:
public function scopeBase($query){
$sql = <<<SQL
id IN(
SELECT DISTINCT users.id FROM articles
INNER JOIN offers
ON articles.id=offers.article_id
INNER JOIN users
ON users.id=articles.user_id
WHERE articles.user_id=? AND users.admin=?
)
SQL;
return $query->whereRaw($sql, [$this->id, 9]);
}
Then in the controller to get the users use this syntax:
class MyController extends Controller{
public function example(){
$users = User::base()->get();
//....
}
}
However if you explain better the table structure you will be grateful.
Did you try this?
foreach (User::all() as $user) {
foreach ($user->offers as $offer) {
if ($offer->article->user->isAdmin())
$select[] = $user;
}
}

$users = User::with('departments')
->whereHas('departments', function ($q) use ($departments) {
return $q->whereIn('department_id', $departments);
})->whereNotNull('users.email')
->get();
public function users(){return $this->morphedByMany(User::class, 'departmentable');}
in department model
and
public function departments(){return $this->morphToMany(Department::class, 'departmentable');
}
in user model
in your whereIn statement you use department_id column in departments table, are you sure of this, isn't just 'id' ('departments.id')?
$users = User::with('departments')
->whereHas('departments', function ($q) use ($departments) {
return $q->whereIn('departments.id', $departments);
})->whereNotNull('users.email')
->get();
I have this query filter which works fine to query out the result. For example, if I need to find books which have the Author name something:
Book::with('user', 'author')
->whereHas('author', function ($query) use($filters) {
$query->filter($filters);
})->paginate(30);
But the thing is if I want to order the Books by the author names. I this case nothing happens.
How can I sort books by author name?
QueryFilter looks like this:
public function __construct(Request $request) {
$this->request = $request;
$this->filterService = new FilterService();
}
public function apply(Builder $builder) {
$this->builder = $builder;
foreach ($this->filters() as $name => $value) {
if (method_exists($this, $name)) {
call_user_func_array([$this, $name], array_filter([$value]));
}
}
return $this->builder;
}
public function filters() {
return $this->filterService->removeEmptyFieldsFromRequest($this->request);
}
And the book filter looks like this:
public function date($date) {
return $this->builder->where('date', $date);
}
public function name_sort($order = 'asc') {
return $this->builder->orderBy('name', $order);
}
You can use class join statement :
$books = Book::select('author.name AS author_name, countries.*')
->with('user')
->join('author', 'author.id', '=', 'book.author_id')
->orderBy('author.name', 'ASC')
->paginate(10);
In my app admin users can create articles. Articles table is: ID | user_id | title ...
For every Article other user (which not admin) can post an offer and Offer table is: ID | user_id(not admin) | article_id | price ...
Now I need to get all users for an admin user which post Offer to their Article... I try:
public function userbase()
{
$id = Auth::user()->id;//get admin id
$articles = Article::where('user_id', $id)->get();//select all admin articles
foreach ($articles as $article) {
$users = Offer::where('article_id', $article['id'])->orderBy('created_at', 'desc')->get(); //get all admin users
}
return $users;
}
but I get just: []
also my Model is:
Article:
public function offers() {
return $this->hasMany('App\Offer');
}
Offer:
public function user() {
return $this->belongsTo('App\User');
}
public function article() {
return $this->belongsTo('App\Article');
}
So how I can get all user details which was posted offer to an admin user?
UPDATE
I also try this:
$articles = Article::with([
'offers' => function($query) {
$query->orderBy('created_at', 'desc');
$query->with('user'); // if you want to eager load users for each offer too...
}
])->where('user_id', Auth::id())->get();
and I get this data:http://i.imgur.com/0kBVGrx.png
but how to access user data? I try ->get('user') but dont work...
2. UPDATE:
I also try:
public function userbase()
{
$articles = Auth::user()->articles()->get();
foreach ($articles as $article) {
$offers = Offer::where('article_id', $article['id'])->orderBy('created_at', 'desc')->get();
}
foreach ($offers as $offer) {
$users = User::where('id', $offer['user_id'])->orderBy('created_at', 'desc')->get();
}
return $users;
}
but I get undefined variable users
Try this :
First, you may add an attribute 'isAdmin' in your User model.
public function userbase()
{
return Offer::select('users.*')
->where('users.isAdmin', false)
->join('articles','articles.id','=','offers.article_id')
->join('users','users.id','=','articles.user_id')
->where('articles.user_id', Auth::user()->id)
->orderBy('offers.created_at', 'desc')
->groupBy('users.id')
->get();
}
Updating Your solution :
public function userbase()
{
$articles = Auth::user()->articles;
foreach ($articles as $article) {
$offers = Offer::where('article_id',$article->id)->orderBy('created_at', 'desc')->get();
}
$users = array();
foreach ($offers as $offer) {
$users[] = User::where('id', $offer['user_id'])->orderBy('created_at', 'desc')->get();
}
return $users;
}
I want to get all the books under a certain category. The category has many subjects and books are linked to subjects.
My code:
class BookCategory extends Model {
public function subjects() {
return $this->hasMany('BookSubject', 'category_id', 'id');
}
public function getBooksAttribute() {
return Books::whereHas('subjects', function ($query) {
return $query->join('book_category', 'book_category.id', '=', 'book_subject.subject_id')
->where('book_category.id', $this->id);
})->get();
}
}
and my Books model:
class Books extends Model {
public function subjects() {
return $this->belongsToMany('BookSubject', 'book_by_subject', 'book_id', 'subject_id');
}
}
If I do:
$cats = \App\Models\BookCategory::all();
foreach ($cats as $c) {
echo $c->books->count();
}
It's always returning 0 for all the rows. What I'm I doing wrong?
I believe the problem is in your subquery:
return $query->join('book_category', 'book_category.id', '=', 'book_subject.subject_id')
->where('book_category.id', $this->id);
I'm pretty sure book_subject.subject_id should be book_subject.category_id
Hard to tell without seeing your db schema.
I can get the list of Likes that User 1 did on a Media from Store 1
$medias = User::find(1)->likes()->with('media')->whereHas('media', function($q) {
$q->where('store_id', '=', 1);
})->get();
But i need to retrieve the list of medias, so i tried
$medias = User::find(1)->likes()->with('media')->whereHas('media', function($q) {
$q->where('store_id', '=', 1);
})->get()->media;
But then i get
Undefined property: Illuminate\Database\Eloquent\Collection::$media
class User extends Model
{
public function likes()
{
return $this->hasMany('App\Like');
}
}
class Media extends Model
{
public function store()
{
return $this->belongsTo('App\Store');
}
public function likes()
{
return $this->hasMany('App\Like');
}
}
class Like extends Model
{
public function user()
{
return $this->belongsTo('App\User');
}
public function media()
{
return $this->belongsTo('App\Media');
}
}
This is because you get media separate for each like. You should use:
$likes = User::find(1)->likes()->with('media')->whereHas('media', function($q) {
$q->where('store_id', '=', 1);
})->get();
foreach ($likes as $like) {
$media = $like->media;
// now you can do something with your media
}
EDIT
If you want to get only media, you should add to your User model the following relationship:
public function medias()
{
return $this->hasManyThrough('App\Media','App\Like');
}
Now to get your media, you should do :
$medias = User::find(1)->medias()->where('store_id', '=', 1)->get();
Made it work with
$store->medias()->whereHas('likes', function($q) use($user) {
return $q->where('user_id', '=', $user->id);
});
