I have a json field in my database name is permissions {"read": true, "create": true}. Now, I want to show this in my blade view. I had try this way but it's show an error.
#foreach($users as $user)
<tr>
<td>{{$user->roles->permissions}}</td>
</tr>
#endforeach
show this Error Message.
Property [permissions] does not exist on this collection instance.
User Model
public function roles()
{
return $this->belongsToMany(Role::class,'user_roles');
}
I tested this scenario and was OK . i hope usefull for you :
my route :
Route::get('/test', function (Request $request) {
$users=\App\User::with('roles')->get();
return view('welcome',compact('users'));
});
define roles method inside user model :
public function roles()
{
return $this->belongsToMany(Role::class,'user_roles');;
}
and get permissions in view :
#foreach($users as $user)
#foreach($user->roles as $role)
<tr>
<td>{{$role}}</td>
</tr>
#endforea
#endforeach
I test with these tables
user_roles
user_id | role_id
-----------------
1 | 2
1 | 2
roles:
id | permissions
-----------------
1 | {"read": true, "create": true}
2 | {"read": true, "create": false}
users:
id | name | email | password | remember_token | created_at|updated_at
----------------------------------------------------------------------

How can I update multiple rows at the same time by their report_id? My Inventory table looks like this:
| id | report_id | product_id | shelf_quantity | display_quantity |
|----|-----------|------------|----------------|------------------|
| 1 | 2 | 12 | 1 | 5 |
| 2 | 2 | 13 | 2 | 6 |
| 3 | 2 | 14 | 3 | 23 |
My attempt to solve the problem:
My controller:
function update($id, Request $request) {
$report = Report::find($id);
$inputs = $request->input('display');
$report->user_id = $user_id;
$report->save();
//Updating inventory table
$inventory = Inventory::where('report_id', $report->id)->get();
foreach($inputs as $key => $value) {
$inventory->display = $request->input('display')[$key] ?: 0;
$inventory->storage = $request->input('storage')[$key] ?: 0;
$inventory->save();
}
My web route:
Route::put('/reports/{id}', 'ReportController#update');
The problem here is that it is only saving the last value that I input.
Additional information
I'm also using the same code in storing new rows and it's working fine. Please see code below:
public function store(Request $request) {
//Adding inventory table
$new_inventories = new Inventory();
foreach($inputs as $key => $value) {
$data[] = [
'user_id' => $user_id,
'report_id' => $new_report->id,
'display' => $request->input('display')[$key] ?: 0,
'storage' => $request->input('storage')[$key] ?: 0,
'product_id' => $request->product_id[$key],
'created_at' => $now,
'updated_at' => $now,
// 'remark' => $request->remark[$key] ?? null,
];
}
Inventory::insert($data);
//End of inventory table
}
Any form of help would be appreciated. Thank you!
EDIT:
My form looks like this:
<form action="/reports/{{$report->id}}" method="post">
#csrf
{{method_field('PUT')}}
#foreach($products as $product)
<input type="number" name="product_id[]" value="{{ $product->id}}" hidden>
<input type="number" name="storage[]">
<input type="number" name="display[]">
#endforeach
</form>
You cannot update multiple rows in one shot. In this case the best way is to get one by one the items in inventory and update them. So you loop through $request->input('product_id'), get the Inventory model for that product_id and $report->id, update and save.
for($i=0; $i<count($request->input('product_id');$i++) {
$inventory = Inventory::where('report_id', $report->id)->where('product_id', $request->input('product_id')[$i])->first();
$inventory->display = $inventory->display = $request->input('display')[$i];
$inventory->storage = $inventory->storage = $request->input('storage')[$i];
$inventory->save();
}
I'm working on a project with Laravel and Eloquent/MySQL.
I'd like to know how to handle a many-to-many relationship with three tables (users, merchants, roles).
Any user can have one or more merchant.
Any merchant can be shared between users.
Any user have a specific role for a merchant.
Is there a best practice to follow?
How can I get all the merchants by a user having a specific role?
Thanks for helping
This is my current structure:
Users
-------------------------------
| id | first_name | last_name |
-------------------------------
Merchants
-------------------
| id | trade_name |
-------------------
Roles
-------------------------
| id | name | hierarchy |
-------------------------
merchant_user_role
-----------------------------------
| merchant_id | user_id | role_id |
-----------------------------------
Merchant Model
<?php
class Merchant extends Model
{
public function users()
{
return $this->belongsToMany('App\User', 'merchant_user_role')
->withPivot('role_id')
->withTimestamps()
->orderBy('first_name', 'asc');
}
}
User Model
<?php
class User extends Model
{
public function merchants()
{
return $this->belongsToMany('App\Merchant', 'merchant_user_role')
->withPivot('role_id')
->withTimestamps()
->orderBy('trade_name', 'asc');
}
public function roles()
{
return $this->belongsToMany('App\Role', 'merchant_user_role')
->withTimestamps();
}
}
Role Model
<?php
class Role extends Model
{
public function users()
{
return $this->belongsToMany('App\User')->withTimestamps();
}
}
$merchants = $user->merchants()->where('role_id', $some_role_id)->get();
I have a couple of tables I'm trying to associate in Sequelize -- a jobaids_sections_messages table containing messages a user enters, and a jobaids_sections_messages_levels table which is a static reference used by the messages table. They're set up like so
this.jobaidMessage = sequelize.define('jobaids_sections_messages', {
message: Sequelize.STRING,
attuid: Sequelize.STRING,
level: Sequelize.INTEGER
}, {
paranoid: true
});
this.jobaidMessageLevel = sequelize.define('jobaids_sections_messages_levels', {
name: Sequelize.STRING
}, {
timestamps: false
});
The jobaids_sections_messages_levels table is set up like so:
| id | name |
| --- | -------- |
| 1 | Critical |
| 2 | Major |
| 3 | Warning |
| 4 | Info |
I want to make is so that when I create a new message, I can pass the level in as a key to the jobaids_sections_messages_levels table, and upon retrieving a message, I get the level back as
{
...
level: {
id: 2,
name: 'Major'
}
}
How should I set my associations up here? So far, I have
this.jobaidMessageLevel.belongsTo(this.jobaidMessage, {
foreignKey: 'level'
});
Though I'm not sure about the reversal of this association. Would it be a "many-to-one" relationship of some sorts?
Thank you!
Your message has a single level and technically your levels can have many messages. So simply stating that your message hasOne level will do the association needed. Then when you pull down a message and include the level, it will come back.
this.jobaidMessage.hasOne(this.jobaidMessageLevel, {
foreignKey: 'levelId'
});
I'm using MySQL and i have schema like:
|------------|-------------|------------|--------------|
| cities |category_city| categories| companies |
|------------|-------------|------------|--------------|
| id | city_id | id | id |
| name | category_id | name |subcategory_id|
| | | parent_id | city_id |
| | | |...other cols |
|____________|_____________|____________|______________|
Relationships:
City with Category has ->belongsToMany()
public function categories()
{
return $this->belongsToMany(Category::class);
}
Categories has subcategories:
public function subcategories()
{
return $this->hasMany(Category::class, 'parent_id', 'id');
}
And i'm getting companies from category and filtering by city, because i need the current city companies and for that i have a global scope:
public function getCompanies($city_id)
{
return $this->companies()->whereHas('mainCity', function ($q) use ($city_id) {
$q->where('city_id', $city_id);
});
}
mainCity method:
public function mainCity()
{
return $this->belongsTo(City::class, 'city_id');
}
Here is my method performing the query with AJAX request:
public function getPlaces(City $city, Category $subcategory, $north, $south, $east, $west)
{
$companies = $subcategory->companies()
->withCount('comments')
->companiesByBounds($north, $south, $east, $west)
->paginate(8);
$markers = $subcategory->companies()
->companiesByBounds($north, $south, $east, $west)
->get(['lat', 'lng', 'slug', 'title']);
return response()->json(['companies' => $companies, 'markers' => $markers], 200, [], JSON_NUMERIC_CHECK);
}
and by companiesByBounds scope method:
public function scopeCompaniesByBounds($query, $north, $south, $east, $west)
{
return $query->whereBetween('lat', [$south, $north])
->whereBetween('lng', [$west, $east]);
}
In companies i have ~2m records. The main problem is that the queries taking 3.5 seconds. Help please to improve my queries.
Here is the query:
select count(*) as aggregate from `companies` where `companies`.`category_id` = '40' and `companies`.`category_id` is not null and `lat` between '53.68540097020851' and '53.749703253622705' and `lng` between '91.34262820463869' and '91.51600619536134'
To improve speed you need to add indexes on the columns lat and lng.
CREATE INDEX idx_lat ON companies (lat);
The indexes are used in queries when the columns are added to conditions.
I have one games table and two tables to store their scores, game_scores and thirdparty_game_scores with exactly the same structure, something like that:
-------------------------GAMES-------------------------
slug | title | technology | (other non-relevant fields)
-------------------------------------------------------
----------------------GAME SCORES----------------------
id (PK) | game_slug | user | team | score | timestamp
-------------------------------------------------------
----------------THIRDPARTY GAME SCORES-----------------
id (PK) | game_slug | user | team | score | timestamp
-------------------------------------------------------
And their Models like:
class GameScores extends BaseGamesModel {
public function initialize() {
parent::initialize();
$this->belongsTo( 'game_slug', 'Games', 'slug' );
$this->skipAttributes(array('creation_time', 'last_modified'));
}
}
I'm building a weekly ranking with game scores stored only on game_scores:
$ranking = GameScores::sum(
array(
"column" => "score",
"conditions" => $conditions,
"group" => "team",
"order" => "sumatory DESC"
)
);
Is there any way to create a Model that concatenates all data from game_scores and thirdparty_game_scores to create the same ranking without any extra effort?
Thank you so much!
You can set the source table dynamically in your model. See Can I build a Model for two Tables on PhalconPHP?
You should use the setSource() method and put your condition in there, e.g.:
$source = 'default_table';
if (class_name($this) === 'A') {
$source = 'A_table';
}
return $source;
