Question

我尝试在laravel中实现默认的身份验证登录系统

PropertyName

在运行上述命令时，仅创建迁移文件，而不是创建表。此外，我试图重新安装作曲家，但它没有工作

long result = Utilities.ConvertTo<Student>(dt ,out listStudent);

// Generic Method
public class Utilities
{
    public static long ConvertTo<T>(DataTable table, out List<T> entity)
    {
        long returnCode = -1;
        entity = null;

        if (table == null)
        {
            return -1;
        }

        try
        {
            entity = ConvertTo<T>(table.Rows);
            returnCode = 0;
        }

        catch (Exception ex)
        {
            returnCode = 1000;
        }

        return returnCode;
    }

    static List<T> ConvertTo<T>(DataRowCollection rows)
    {
        List<T> list = null;
        if (rows != null)
        {
            list = new List<T>();

            foreach (DataRow row in rows)
            {
                T item = CreateItem<T>(row);
                list.Add(item);
            }
        }

        return list;
    }

    static T CreateItem<T>(DataRow row)
    {
        string str = string.Empty;
        string strObj = string.Empty;

        T obj = default(T);

        if (row != null)
        {
            obj = Activator.CreateInstance<T>();
            strObj = obj.ToString();
            NameValueCollection objDictionary = new NameValueCollection();

            foreach (DataColumn column in row.Table.Columns)
            {
                PropertyInfo prop = obj.GetType().GetProperty(column.ColumnName);

                if (prop != null)
                {
                    str = column.ColumnName;

                    try
                    {
                        objDictionary.Add(str, row[str].ToString());
                        object value = row[column.ColumnName];
                        Type vType = obj.GetType();

                        if (value == DBNull.Value)
                        {
                            if (vType == typeof(int) || vType == typeof(Int16)
                                                     || vType == typeof(Int32)
                                                     || vType == typeof(Int64)
                                                     || vType == typeof(decimal)
                                                     || vType == typeof(float)
                                                     || vType == typeof(double))
                            {
                                value = 0;
                            }

                            else if (vType == typeof(bool))
                            {
                                value = false;
                            }

                            else if (vType == typeof(DateTime))
                            {
                                value = DateTime.MaxValue;
                            }

                            else
                            {
                                value = null;
                            }

                            prop.SetValue(obj, value, null);
                        }

                        else
                        {
                            prop.SetValue(obj, value, null);
                        }
                    }

                    catch(Exception ex)
                    {

                    }
                }
            }

            PropertyInfo ActionProp = obj.GetType().GetProperty("ActionTemplateValue");

            if (ActionProp != null)
            {
                object ActionValue = objDictionary;
                ActionProp.SetValue(obj, ActionValue, null);
            }
        }

        return obj;
    }
}

正在运行

      php artisan make:migration create_users_table
      Created Migration: 2016_03_10_115611_create_users_table

花了一些时间并返回

//In 2016_03_10_115611_create_users_table file
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateUsersTable extends Migration
{
 /**
 * Run the migrations.
 *
 * @return void
 */
 public function up()
 {
    Schema::create('users', function (Blueprint $table) {
        $table->increments('id');
        $table->string('name');
        $table->string('email')->unique();
        $table->string('password');
        $table->rememberToken();
        $table->timestamps();
    });
 }

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

感谢大家，我没有正确配置.env文件，因此无法正常工作

Answer 1

你的MySQL版本是什么？或者你尚未修改.env

尝试SQLite并将设置数据库更改为sqlite。我认为这个问题在php扩展。

首先，您已运行此命令以安装迁移

php artisan migrate:install

注意： - 如果查看数据库/迁移，则会有两个迁移文件

2014_10_12_000000_create_users_table.php
2014_10_12_100000_create_password_resets_table.php

php artisan migrate

Laravel迁移不起作用
