I am trying to search with a column on a connected table using with. According to laravel the following should work.
$lineItems = Invoice::with(['invoiceHeader' => function ($query) {
$query->where('community_id', '=', 1);
}, 'invoiceLineItems'])
->limit(10)
->get()
->toArray();
However, I don't get anything from the invoiceHeader table and I get all the invoices available. If I take out the function I get the same but with invoiceHeader's table values showing up.
$lineItems = Invoice::with(['invoiceHeader', 'invoiceLineItems'])
->limit(10)
->get()
->toArray();
It seems I might be doing something of a right join where I get all the Invoices but then only the invoiceHeader values when applicable to the foreign key.
Edit:
I put ->toSql(); after the limit() and it shows I only get the following.
"select * from `invoice` limit 10"
You should use whereHas mixing with with:
$lineItems = Invoice::with(['invoiceHeader', 'invoiceLineItems'])
->whereHas('invoiceHeader', function ($query) {
return $query->where('community_id', 1);
})
->limit(10)
->get()
->toArray();

I want to retrieve a collection of data, which is ordered by the start_date of the relation
Basically I want to achieve this, with Laravel Models (the code below works perfectly)
$posts = DB::table('posts')
->leftJoin(
'threads',
'posts.id',
'=',
'threads.postable_id'
)
->where('threads.postable_type', '=', 'App\Post')
->orderBy('threads.start_date')
->paginate($request->input('limit', 2));
So in this case, I'm fetching ALL Posts and those are ordered by the start_date of the thread relation.
Those are not my actual tables but this works perfectly!
Because I'm using https://laravel.com/docs/8.x/eloquent-resources this is not the ideal solution to retrieve sorted data.
So instead I want to use the orderBy clause somewhere here
$posts = Post::whereHas('thread', function ($query) {
$query->where('end_date', '>=', Carbon::now());
});
But I just cannot make this work. I've tried this
$posts = Post::whereHas('thread', function ($query) {
$query->where('end_date', '>=', Carbon::now())
->orderBy('start_date');
});
and I also appended this to the actual relation:
public function thread(): MorphOne
{
return $this->morphOne('App\Thread', 'postable')->orderBy('start_date');
}
If you look at your code:
$posts = Post::whereHas('thread', function ($query) {
$query->where('end_date', '>=', Carbon::now())
->orderBy('start_date');
});
the whereHas will only return Post associate with a thread which the function return true.
Try this:
$posts = Post::with('thread')->has('thread')->orderBy('thread.start_date')->get();
This will fetch all Post with Thread only if they have at least one Thread and then orderBy the start_date of the Thread.
You don't have to do the whereHas function because when you call ->with('thread') it'll use you this :
public function thread(): MorphOne
{
return $this->morphOne('App\Thread', 'postable')->orderBy('start_date');
}
whereHas doesnt retrieve the relationship.
If you need even more power, you may use the whereHas and orWhereHas methods to define additional query constraints on your has queries, such as inspecting the content of a comment: Laravel whereHas
Don't do :
$posts = Post::with('thread')->orderBy('thread.start_date');
If there is no thread on some post, post without thread will be fetch with value null for their key thread and you will have an unexpected result when you try to orderBy.
First of all I want to thank Elie Morin for his help but I found out that I definitely need to use joins for that task.
In my example, I wanted to order the main query (posts) by the relation's start_date
Doing what you suggested
$posts = Post::with('thread')->has('thread')->orderBy('thread.start_date')->get();
Would only order the thread by start_date and not the ENTIRE query.
Which is why I came up with something like this:
$posts = Post::has('thread')
->select('posts.id')
->leftJoin(
'thread',
'posts.id',
'=',
'thread.postable_id'
)
->where('thread.postable_type', '=', 'App\Post')
->where('thread.end_date', '>=', Carbon::now())
->orderBy('thread.start_date')
->with('thread');
return PostResource::collection($posts->paginate(2));
Trying to get this query to work in eloquent
A user can be in multiple teams however I want to generate a list of users NOT in a specific team. The following SQL query works if executed directly but would like to make it cleaner by converting it to eloquent
SELECT * FROM users LEFT JOIN team_members ON team_members.member_id = users.id WHERE NOT EXISTS ( SELECT * FROM team_members WHERE team_members.member_id = users.id AND team_members.team_id = $team_id )
This should provide a list of all the users that are not members of team $team_id
This is a guess ad you do not give much info on your Eloqent models but here is a hint of where to go:
User::doesnthave('teamMembers', function($builder) use($team_id){
return $builder->where('team_members.team_id');
});
That is assuming you have a "User" model with a "teamMembers" relationship setup on it
You may have a closer look in the Laravel docs for doesntHave
Laravel 5.8
Let's assume you have model name "User.php"
& there is method name "teamMembers" in it.
Basic
$users = User::doesntHave('teamMembers')->get();
Advance
use Illuminate\Database\Eloquent\Builder;
$users = User::whereDoesntHave('teamMembers', function (Builder $query) {
$query->where('id', '=', {your_value});
})->get();
You can find details description in this link >>
https://laravel.com/docs/5.8/eloquent-relationships#querying-relationship-absence
Laravel 5.2
Example:
DB::table('users')
->whereExists(function ($query) {
$query->select(DB::raw(1))
->from('orders')
->whereRaw('orders.user_id = users.id');
})
->get();
Check this link for advance where clause:
https://laravel.com/docs/5.2/queries#advanced-where-clauses
You can use below example
$list = User::leftJoin('users', 'users.id', '=', 'team_members.member_id')
->whereNotExists(function ($query) use ($team_id) {
$query->from('team_members')
->whereRaw('team_members.member_id = users.id')
->where('team_members.team_id', '=', $team_id);
})
->get();
I have a function to get a pass a language number to get language categories record for API purpose. I use a database query statement to select categories table and join the category language table to get category id, parent_id and name (specified language). When execute return error and select the underlying SQL converted the language value to string (e.g. languages_id = 1). I google a lot and no ideas what's wrong. Can anyone advise how to resolve. Thanks a lot.
I tried to copy the underlying SQL to MySQL Workbench and remove the languages_id = 1 --> languages_id = 1 can working properly. I guess the 1 caused error.
Code Sample:
private function getCategories($language) {
$categories = DB::table('categories')
->select(DB::raw('categories.id, categories.parent_id, categories_translation.name'))
->join('categories_translation', function($join) use ($language) {
$join->on('categories_translation.categories_id', '=', 'categories.id');
$join->on('categories_translation.languages_id', '=', $language);
})
->where([
['parent_id' ,'=', '0'],
['categories.id', '=', $id]
])
->get();
return $categories;
}
Error return the converted SQL:
"SQLSTATE[42S22]: Column not found: 1054 Unknown column '1' in 'on
clause' (SQL: select categories.id, categories.parent_id,
categories_translation.name from categories inner join
categories_translation on categories_translation.categories_id =
categories.id and categories_translation.languages_id = 1
where (parent_id = 0 and categories.id = 1))"
You are trying to join using a comparison to an scalar value, instead of a column. I think you actually want to put that comparison as a "where" condition, rather than a "join on"
->where([
['parent_id' ,'=', '0'],
['categories.id', '=', $id],
['categories_translation.languages_id', '=', $language]
])
there is another thing i just discover with your code. when joining table, you are suppose to be joining 'categories_translation.languages_id' with another table id field. in your case, it is not so. you are not joining 'categories_translation.languages_id' with any table field. so ideally, what you are going to do is this
private function getCategories($language) {
$categories = DB::table('categories')
->select(DB::raw('categories.id, categories.parent_id, categories_translation.name'))
->join('categories_translation', function($join) use ($language) {
$join->on('categories_translation.categories_id', '=', 'categories.id');
})
->where([
['parent_id' ,'=', '0'],
['categories.id', '=', $id]
['categories_translation.languages_id', '=', $language]
])
->get();
return $categories;
}
hope this helps
I am using two tables and a pivot table
Table 1 named calendars.
Table 2 named calendar_groups.
Pivot table calendar_calendar_group.
I'm trying to get data from Table 1 based on a where value in the pivot table. Where calendar_groups_id = 1 then use calendar_id to get data from table 1. I can't get it to work.
$event = new Calendar();
$event->orderBy('start', 'asc')
->whereHas('calendar_groups', function ($q) {
$q->wherePivot('calendar_groups_id', '=', '1');
})->with('calendar_groups')
->first();
This gives me the following error:
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'pivot' in
'where clause'
This is the relationship:
public function calendar_groups()
{
return $this->belongsToMany(CalendarGroup::class);
}
Your help is very much appreciated.
I think #Tpojka is right here. If you're trying to get Calendar instances that belong to desired CalendarGroup then replace the code should look like this:
$event = new Calendar();
$group = 1;
$event->orderBy('start', 'asc')
->whereHas('calendar_groups', function ($q) use ($group) {
//$q->wherePivot('calendar_groups_id', '=', $group);
$q->where('id', '=', $group);
})->with('calendar_groups')
->first();
If I'm reading the documentation correctly wherePivot() should be used like this:
$event = new Calendar();
$event->calendar_groups()->wherePivot('some_pivot_column',1)->get();
But this would return you the CalendarGroup instances.
If you'd want to do it through Eloquent but without going all the way to the CalendarGroup then you'd probably need to create a Model (let's call it CalendarCalendarGroupPivot) for the pivot table and add another relation (hasMany('CalendarCalendarGroupPivot')) to your Calendar model.
Ok finally got it working.
I used your suggestions but still don't understand a little part of it.
When I use the suggestions made:
$event = new Calendar;
$event->orderBy('start', 'asc')
->whereHas('calendar_groups', function($q) {
$q->where('calendar_group_id', '=', '1');
})->with('calendar_groups')
->first();
I get an empty collection.
But if I run this:
$event = Calendar::orderBy('start', 'asc')
->whereHas('calendar_groups', function($q) {
$q->where('calendar_group_id', '=', '1');
})->with('calendar_groups')
->first();
I get the desired results
Can anybody tell me the difference between so I can learn from it?
I have the following which returns a collection of objects;
$cwGames = Schedule::where('date', '<', Carbon::now()->addDays(7))
->where('date', '>', Carbon::now()->addDays(1))->get();
Now I want to select from this collection only the object where $id is in col A or $id is in col B.
What's the best way to do this? Thanks.
Thanks to ExoticChimp for direction on the answer below. I added the use ($id) to get it to work. See edit here...
$cwGames = Schedule::where('date', '<', Carbon::now()->addDays(7))
->where('date', '>', Carbon::now()->addDays(1))
->where(function ($query) use ($id) {
// Replace col_A and col_B with your column names
$query->where('home_team_id', $id)
->orWhere('away_team_id', $id);
})->get();
The question is slightly ambiguous what you mean by col A and col B. However, if what you want is to add in an additional where clause which is effectively if colA or colB = $id, then the following should work (from the Laravel docs)
$cwGames = Schedule::where('date', '<', Carbon::now()->addDays(7))
->where('date', '>', Carbon::now()->addDays(1))
->where('name', '=', 'John')
->where(function ($query) {
// Replace col_A and col_B with your column names
$query->where('col_A', $id)
->orWhere('col_B', $id);
})
->get();

Laravel Collections has a lot of cool features that I think you should check on the official docs. In your case, the "filter" method is the best way to process the elements of your collection.
According to the official docs:
The filter method filters the collection by a given callback, keeping only those items that pass a given truth test
In your case:
$cwGames->filter(function($value, $key) {
// If your check returns true, the element will be kept in the collection
}
Check the docs here (filter method explained)
