Question

我收到这样的错误，请帮忙解决，如果将其删除（“ published”，“ created_by”，“ modified_by”），则一切正常。如何清除此错误？我会先感谢您的帮助类别php

class category extends Model
{
     protected $fillable = ['title','slug','parent_id','published', 'created_by', 'modified_by'];


    public function setSlugAttribute($value){
        $this->attributes['slug'] = Str::slug( mb_substr($this->title, 0, 40) . "-" . \Carbon\Carbon::now()->format('dmyHi'), '-');
    }   
    public function children(){
        return $this->hasMany(self::class, 'parent_id');
    }
}

create_categories_table

Schema::create('categories', function (Blueprint $table) {
            $table->increments('id');
            $table->string('title');
            $table->string('slug');
            $table->integer('parent_id')->nulltable();
              $table->tinyinteger('published',0)->nulltable();
              $table->integer('created_by')->nulltable();
             $table->integer('modified_by')->nulltable();
             $table->timestamps();
        });

Answer 1

在create_categories_table中替换为以下代码：

$table->integer('parent_id')->nullable();
$table->tinyinteger('published')->default(0)->nullable();
$table->integer('created_by')->nullable();
$table->integer('modified_by')->nullable();

虽然您在表中保存了一些记录，但是您没有传递一些字段，所以它应该具有默认值，否则为空

当您通过nulltable时，我在这里看到错误，应该是nullable。

Schema::create('categories', function (Blueprint $table) {
            $table->increments('id');
            $table->string('title');
            $table->string('slug');
            $table->integer('parent_id')->nullable();
            $table->tinyinteger('published',0)->nullable();
            $table->integer('created_by')->nullable();
            $table->integer('modified_by')->nullable();
            $table->timestamps();
        });

常规错误：1364“发布”字段没有默认值
