I have a database table erp_product and database table oc_product, I need them to have the same value in all records. I created a route called atualizador.
Route:
Route::get('/atualizador', 'JoshController#updatetables');
And a function in Controller
public function updatetables()
{
$oc = OCProduct::all();
$erp = Product::all();
return view('admin.atualizasite')->with('message', 'Banco atualizado com sucesso!');
}
Can I create an update with eloquent usage like two tables from different database?
Any suggestion?
It works, I used DB :: statement, Thanks guys.

I am trying to query data from my database and pass the results to a view called events, the problem I have is that one of my queries will always return the same result because in the where condition the $events_id is the same always. Is there a better way to do the querying? A better logic?
This code is from my controller called EventController:
public function index()
{
$firm_id = DB::table('firms')->where('user_id', auth()->id())->value('id');
$events_id = DB::table('events')->where('firm_id', $firm_id)->value('id');
$events = DB::table('events')->where('firm_id', $firm_id)->get()->toArray();
$actual_events = DB::table('actual_events')->where('event_id', $events_id)->get()->toArray();
return view('events',['events' => $events,'actual_events' => $actual_events]);
}
Since the $events_id is the same every time, the $actual_events will only contain the first result.
The image I have uploaded shows the problem, my table's first three columns are fine. Starting from the fourth they contain repeated values:
As I guess, you need something like this:
$event_ids = DB::table('events')->where('firm_id', $firm_id)->pluck('id');
$actual_events = DB::table('actual_events')->whereIn('event_id', $event_ids)->get()->toArray();
or write about your problem in details and I will try to help you.
you just said that your tables have relation together.
in this case it's better you using the eloquent for that,
first you should type the relations in model of each table like this:
class User extends Authenticatable{
public function cities()
{
return $this->hasmany('App\City'); //you should type your relation
}
}
for relations you can use this link: laravel relationships
after that when you compact the $user variable to your view, you can use this syntax for getting the city value relation to this user: $user->cities;.
I'm using Laravel Auditing Package to trace changes on my models.
I want to get a specific column of the foreign key in it's primary table before recording the events (create, update, delete) in the audit table.
There is a way the package helps get all the attribute of the foreign key, it's called Audit Transformation but it generates an error for me when displaying the details in the table i want to know if there's any eloquent model method to get the specific column info i need instead of using getattribute() method which gets the entire row of the item_id.
Audit Transformation Method
public function transformAudit(array $data): array
{
if (Arr::has($data, 'new_values.item_id')) {
$data['old_values']['item_name'] = Item::find($this->getOriginal('item_id'));
$data['new_values']['item_name'] = Item::find($this->getAttribute('item_id'));
}
return $data;
}
This is how it's stores in the database ephasis on the item_name.
{"item_id":"1","qty_received":"2","delivered_by":"John",
"received_by":"Abi","supplier":"Stores","date":"2019-11-26","item_name":{"item_id":1,"item_name":"Toner","colour":"Black","status":"Active",
"created_at":"2018-10-25 17:55:26","updated_at":"2018-10-25 17:55:26"}}
And this is the Item table schema
So in my scenario i'd want to store the item_name as Toner not the entire row of the item_id
Any suggestion will be welcomed, thanks in advance.
Add ->item_name->item_name after the function of Find.
if (Arr::has($data, 'new_values.item_id')) {
$data['old_values']['item_name'] = Item::find($this->getOriginal('item_id'))->item_name->item_name;
$data['new_values']['item_name'] = Item::find($this->getAttribute('item_id'))->item_name->item_name;
}
I have a table content. So when I retrive anything from that table using laravel eloquent, I need to set a global where clause Content::where('is_playlist', 1)->get();, so that every time I retrieve data from that table, I should automatically filtered with that particular where clause.
You can create a scope function in the model to filter that out e.g:
public function scopePlaylist($query)
{
return $query->where('is_playlist', 1);
}
This means you can easily call, Content::playlist()->get() and you'll have only playlist content.
I hope this is useful?
I'm new to Stack Overflow and Laravel.
I try to develop a variable profilesystem in Laravel and I got 3 tables ('User', 'User_Fields', 'Fields').
The structure of the Fields table is following:
The structure of the user_fields table is following:
The User table is the standard table which came with Laravel 5
Now I want to get all fields from user_fields depending on which user is selected or logged in. If the user_field doesn't exists, the model should return null or create a new record for the user_field.
I tried a lot of "solutions" which came with eloquent like (hasManyThrough, belongsToMany) but I don't get the result I wanted.
Is there any solution with relationship methods?
Thanks for your help, and sorry for my bad english :/
You should be using the belongsToMany()->withPivot() to retrieve the intermediate table columns. Your user_fields is your pivot table so on your user model you should have:
class User extends Model
{
public function fields()
{
return $this->belongsToMany(Field::class, 'user_fields')->withPivot('value');
}
}
Then you can access your values for a user by:
$user = User::find($id);
foreach($user->fields as $field) {
$field->pivot->value;
}
I have a model (Client) with a hasMany relationship to another (Client_option).
The two tables are in different databases (so there is a list of clients, and then each client has their own database with an options table within).
In my Client class I want my options() method to return the entire contents of the options table (it knows which client db to look for). As it is I get an error because the column client_id does not exist in the options table. I can of course create that column and populate every row with the client's id, but I'd only be doing it to keep Eloquent happy so would rather avoid that little messiness.
Thanks in advance for any input!

This will allow you to work with it as a relation, call it as dynamic property $user->options, bulk save with push method and so on:
public function options()
{
// it will use the same connection as user model
$options = ClientOption::on($this->getConnectionName())->get();
// if options model has its own, then simply
// $options = ClientOption::get();
$this->setRelation('options', $options);
return $options;
}
public function getOptionsAttribute()
{
return (array_key_exists('options', $this->relations))
// get options from the relation, if already loaded
? $this->getRelation('options')
// otherwise call the method and load the options
: $this->options();
}
