问题 I got several .sql files of countries, states and cities of the world from github. How can I run them with Laravel's seed files to populate those tables in my database? 回答1: Add DB::unprepared() to the run method of DatabaseSeeder . Run php artisan db:seed at the command line. class DatabaseSeeder extends Seeder { public function run() { Eloquent::unguard(); $this->call('UserTableSeeder'); $this->command->info('User table seeded!'); $path = 'app/developer_docs/countries.sql'; DB::unprepared

问题 I am trying to filter a paginated eloquent collection, but whenever I use any of the collection methods, I lose the pagination. $models = User::orderBy('first_name','asc')->paginate(20); $models = $models->each(function($model) use ($filters) { if(!is_null($filters['type'])) { if($model->type == $filters['type']) return $model; } if(!is_null($filters['state_id'])) { if($model->profile->state_id == $filters['state_id']) return $model; } if(!is_null($filters['city_id'])) { if($model->profile-

问题 I have two models called Page and User and I've set up the Eloquent relation as follows: public function user() { return $this->belongsTo('User') } When I dd(Page::with('user')->get()) I get the right result. But now I want to have a search filter on this result. I've used a scopeSearch but I'm not sure how to search on the resultset. At the moment I have a scope like this: public function scopeSearch($query, $search) { $query->where('username', 'LIKE', '%'.$search.'%') ->orWhere('name',

问题 I'm doing what I want in a certain way and I'm looking for alternatives or better ways of doing. I'm using Resource Controllers in my application.

The second allows me to

问题 My guess was to use the following syntax: MyModel::all()->delete(); But that did not work. I'm sure it's super simple, but I've searched for documentation on the subject and can't find it! 回答1: The reason MyModel::all()->delete() doesn't work is because all() actually fires off the query and returns a collection of Eloquent objects. You can make use of the truncate method, this works for Laravel 4 and 5: MyModel::truncate(); That drops all rows from the table without logging individual row
