Question

这是我的迁移代码.....或您可以说的架构

        // create the svg
        let svgSquare = document.createElementNS('http://http://www.w3.org/2000/svg', 'svg');

        const clickClass = clickAnimationName.length ? `shape-${shapeLayerNum}-click-${clickAnimationName}` : '';
        const mouseEnterClass = mouseEnterAnimationName.length ? `shape-${shapeLayerNum}-mouse-enter-${mouseEnterAnimationName}` : '';
        const mouseLeaveClass = mouseLeaveAnimationName.length ? `shape-${shapeLayerNum}-mouse-leave-${mouseLeaveAnimationName}` : '';

        const svgSquareClasses = `${clickClass} ${mouseEnterClass} ${mouseLeaveClass}`;

        // add svg classes
        // svgSquare.setAttribute('class', svgSquareClasses);

        // set svg attributes
        svgSquare.setAttributeNS("http://www.w3.org/2000/xmlns/", "xmlns:xlink", "http://www.w3.org/1999/xlink");

        svgSquare.setAttribute('viewBox', `0 0 ${shapeScale/2} ${shapeScale/2}`);
        svgSquare.setAttribute('fill', shapeConfig[`shape-${shapeLayerNum}-background`]);
        svgSquare.setAttribute('stroke', 'black');
        svgSquare.setAttribute('stroke-width', `${shapeScale/100}px`);

        // sizing/centering
        svgSquare.setAttribute('z-index', shapeConfig[`shape-${shapeLayerNum}-zIndex`]);
        svgSquare.setAttribute('width', `${(shapeScale) + (shapeSpacing*2)}px`);
        svgSquare.setAttribute('height', `${(shapeScale) + (shapeSpacing*2)}px`);

        svgSquare.setAttribute('style', `margin-left: ${shapeMarginLeft}px; margin-top: ${shapeMarginTop}px;`);

        // create the square rect
        let polySquare = document.createElementNS('http://www.w3.org/2000/svg', 'rect');
        polySquare.setAttribute('width', `${(shapeWidth/2 - (shapeSpacing*2))}`);
        polySquare.setAttribute('height', `${(shapeHeight/2) - (shapeSpacing*2)}`);
        polySquare.setAttribute('x', `${shapeSpacing/2}`);
        polySquare.setAttribute('y', `${shapeSpacing/2}`);

        // rect polygon to svg
        svgSquare.appendChild(polySquare);

当我在laravel上运行时出现错误：

Answer 1

<?php

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

class CreateUsersTable extends Migration
{
  public function up()
{
   Schema::create('users', function (Blueprint $table) {
    $table->increments('id');
    $table->string('to');
    $table->string('from');
    $table->string('mobile')->nullable();
    $table->rememberToken();
    $table->timestamps();
  });
}

 public function down()
 {
  Schema::drop('users');
 }
}

尝试使用此代码，还要检查env文件和database.php中相关数据库的设置

Connection.php中的查询异常
