未找到Laravel Base表或视图

I'm very confused, i try to find what's wrong but i don't find it..

My migration file:

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;

class CreateClientProjectTable extends Migration {

    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('client_project', function(Blueprint $table)
        {
            $table->increments('id');
            $table->integer('client_id');
            $table->integer('project_id');
            $table->timestamps();
        });
    }


    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::drop('client_project');
    }

}

First of all, i check table is created, and it is.

Then, the route who calls to the controller is this: (is prefixed by admin)

Route::post('projectsclients/postUpload', ['uses' => 'AdminController@storeProjectsClients', 'as' => 'admin.projectsclients.store']); 

The functions looks like here:

$client_project = new Client_Project();
$client_project->client_id = DB::table('clients')->orderby('id','DESC')->take(1)->get();
$client_project->project_id = DB::table('projects')->orderby('id','DESC')->take(1)->get();
$client_project->save();

And the error:

Base table or view not found: 1146 Table 'web.client__projects' doesn't exist

The problem is my table is client_project not client__projects.

Where i have to fix this?

Thanks a lot, any help will be appreciated.
