我希望为我的"Candidate"Eloquent模型添加一个geolocation属性.我想根据他们的位置找到候选人.例如,找到距离旧金山20英里范围内的所有候选人.我的Eloquent模型应该如何将候选人的位置存储在数据库中？

如何根据候选人的位置查询候选人？我正在使用Laravel 5.3.

我正在尝试将 Postgres 和 Laravel 6.x 上的列从类型字符串更改为整数。我试图通过这样的迁移来做到这一点：

    public function up()
    {
        Schema::table('job_listings', function (Blueprint $table) {
            $table->integer('company_id')->change();
        });
    }

当我运行此迁移时，我收到一个错误，该列无法自动转换为整数：

In Connection.php line 664:

  SQLSTATE[42804]: Datatype mismatch: 7 ERROR:  column "company_id" cannot be cast automatically to type integer
  HINT:  You might need to specify "USING company_id::integer". (SQL: ALTER TABLE job_listings ALTER company_id TYPE INT)


In PDOStatement.php line 123:

  SQLSTATE[42804]: Datatype mismatch: 7 ERROR:  column "company_id" cannot be cast automatically to type integer
  HINT:  You might need to specify "USING company_id::integer".

我正在尝试安装一个软件包 bower install restangular --save

然后Bower要我选择一个Angular版本:

所以我创建了一个新的Sails.js项目,然后运行

$ sails generate api user

喜欢加载页面建议.但是现在当我启动服务器时sails lift出现错误:

-----------------------------------------------------------------

 Excuse my interruption, but it looks like this app
 does not have a project-wide "migrate" setting configured yet.
 (perhaps this is the first time you're lifting it with models?)

 In short, this setting controls whether/how Sails will attempt to automatically
 rebuild the tables/collections/sets/etc. in your database schema.
 You can read more about the "migrate" setting here:

从我的控制器我想选择所有具有"客户端"角色的用户.

我有一个用户模型和一个角色模型.角色属于许多用户,用户属于许多角色.

我已经建立了我的模型,并在模型实例级别有一些辅助函数来获取角色和用户

以下是用户和角色数据库模型:

应用程序/ user.php的

class User extends Authenticatable
{
    use Notifiable;

    protected $fillable = [
        'name', 'email', 'password',
    ];

    protected $hidden = [
        'password', 'remember_token',
    ];

    // User belongs to many roles
    public function roles()
    {
        return $this->belongsToMany('App\Role')->withTimestamps();
    }

    // whitelist specific roles
    // reject if user does not have given roles
    public function authorizeRoles($roles)
    {
        if ($this->hasAnyRole($roles)) {
            return true;
        }

        abort(401, 'This action is unauthorized.');
    }

我正在尝试按照Michael Hartl的rails教程添加身份验证步骤7.29(http://ruby.railstutorial.org/chapters/sign-up#top).我的项目在本地工作,但当我尝试部署到heroku时,我得到"应用程序中发生错误,并且无法提供页面".这些是我的日志错误:

我使用查询字符串参数成功发出请求：

// Works
var Promise = require("bluebird");
var request = Promise.promisifyAll(require("request"));

request.get({
    url: 'https://api.angel.co/1/tags/' + encodeURIComponent(friscoLocationTag) + '/startups', 
    qs: {
        access_token: myToken,
        order: 'popularity'
    },
    method: 'GET'
}, function(error, response, body){
    // request success
    console.log(body);
});

然而，当我尝试答应我的请求时，我失败了：

// Does Not Work
var Promise = require("bluebird");
var request = Promise.promisifyAll(require("request"));

request.get({
    url: 'https://api.angel.co/1/tags/' + encodeURIComponent(friscoLocationTag) + '/startups', 
    qs: {

        order: 'popularity'
    },
    method: 'GET'
}).then(function(error, response, body){
    console.log(body);

这给出了错误：

我在使用 Codeception 在 PhpStorm 中为我的应用程序运行测试时出错。我的代码正在通过 Vagrant 运行。

在我的用于 Codeception 测试的index.php的第一行是：

ini_set('xdebug.max_nesting_level', 200);

我通过自制软件安装了 xdebug，这在我的 php 版本输出中：

当我运行测试时，虽然我在 PhpStorm 事件日志中收到错误：

在我的 PhpStorm 设置中，我将其设置为接受外部连接：

我有一个简单的package.json,我正在尝试将grunt添加到我的项目中.我已经多次这样做但从未遇到过这个问题

我的package.json:

  "main": "server.js",
  "dependencies": {
    "body-parser": "^1.0.2",
    "express": "^4.1.1",

    "mongoose": "^3.8.8",
    "nodemon": "^1.0.17",
    "request": "^2.34.0"
  }
}

然后从命令行我得到错误:

我的本地计算机上有一个普通的文件网站，并希望使用Sass。在<head>索引页面的中，我有：

<link rel="stylesheet" type="text/css" href="stylesheets/style.scss" />

虽然当我在Chrome中运行此命令时，控制台出现错误：

Resource interpreted as Stylesheet but transferred with MIME type text/plain 来自索引中的链接标记。

如何更改模因类型，以便Chrome呈现我的Sass样式？

我正在尝试开始使用PHPunit。我使用composer init命令创建了一个新的composer.json文件。看起来像这样：

{
    "name": "connor11528/stitch-labs-woo-shipment-sync",
    "authors": [
        {
            "name": "Connor Leech",
            "email": "connor@stitchlabs.com"
        }
    ],
    "require": {}
}

当我尝试安装PHPunit软件包时，出现错误：

[UnexpectedValueException]                                                        
  Could not parse version constraint README.md: Invalid version string "README.md" 

我正在按照PHPunit入门（此处）中概述的说明安装软件包：

$ php -v
$ PHP 7.1.13 (cli) (built: Jan  5 2018 15:31:15) ( NTS )
$ composer self-update
$ composer require --dev phpunit/phpunit ^7

我的文件结构是：

- my-file.php
- composer.json
- README.md

如何克服此错误并安装PHPunit软件包？
