我想访问state.session的instance.js距离records_view.js.这是如何完成的？

存储/模块/ instance.js

const state = {
  // This is what I want to access in records_view.js
  session: {}
};

const getters = {
  sessionGetter: state => state.session
};

存储/模块/ records_view.js

const actions = {
  getSettingsAction (context, props) {
    // This is how I'm trying to access session, which doesn't work
    let session = context.state.instance.session;

    Api(
      context,
      {
        noun: props.noun,
        verb: 'GetRecordsViewSettings',
        orgUnitKey: _.has(session, 'orgunit.key') ? session.orgunit.key : '',
        data: {}
      },
      props.callback
    ); …

我有以下Sass片段,我想让它<thead>在桌子滚动时浮动.这适用于Safari,但不适用于Chrome Version 58.0.3029.110 (64-bit).

我知道Chrome已经再次获得支持sticky,目前支持它,但它是最终的吗？这是Chrome错误还是我需要不同的解决方案？(我更喜欢CSS方法而不是Javascript,因为它更高效.)

.table {
  thead {
    background: white;
    position: sticky;
    top: 0;
    z-index: 10;
  }
}

我有一个自定义查询,它从旧系统中获取数据并将其映射到新系统中的模型.查询如下所示:

$companies = DB::connection('legacy')->select("...");

由于它是大量数据,我想使用Eloquent的块功能(只是从他们的文档中复制的示例代码):

User::chunk(200, function($users)
{
    foreach ($users as $user)
    {
        //
    }
});

我该如何实现？

编辑:我的代码现在看起来像这样,导致没有响应:

DB::connection('legacy')->select("SELECT * FROM companies")->chunk(200, function($companies) {
    foreach ($companies as $company) {
        // dd($company);
        $entity       = Entity::firstOrNew(['external_id' => $company->companyKey]);
        $entity->name = $company->companyName;
        $entity->save();
    }
});

在不失去理智的情况下使路由工作.

错误

Error: Can't resolve all parameters for Router: (?, ?, ?, ?, ?, ?, ?, ?)

app.routing.ts

import { ModuleWithProviders } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';

import { NavbarComponent } from './navbar/navbar.component';

export const appRoutes: Routes = [
    { path: '', redirectTo: 'customers', pathMatch: 'full' },
    { path: 'customers', component: CustomerComponent },

我正在发出POST请求，但除422响应外无法获取其他任何内容。

Vue.js客户端代码：

new Vue({
  el: '#app',

  data: {
    form: {
      companyName: '',
      street: '',
      city: '',
      state: '',
      zip: '',
      contactName: '',
      phone: '',
      email: '',
      numberOfOffices: 0,
      numberOfEmployees: 0,
    }
  },

  methods: {
    register: function() {
      this.$http.post('/office-depot-register', this.form).then(function (response) {

        // success callback
        console.log(response);

      }, function (response) {

        // error callback
        console.log(response);

      });
    }
  }
});

Laravel路线：

Route::post('/office-depot-register', ['uses' => 'OfficeDepotController@register', 'as' => 'office-depot-register']);

Laravel控制器：

public function register(Request $request)
{
    $this->validate($request, [
        'companyName' => 'required',
        // ...
    ]);

    // …

我正在尝试在我的HTTP响应中发回一个JSON编码的MongoDB对象.我跟着其他几个类似的问题,但我仍然遗漏了一些东西.没有异常被抛出,但我<api.views.MongoEncoder object at 0x80a0c02c>在浏览器中得到了一个神秘的回应.我相信这很简单,但任何帮助都会受到赞赏.

     def _iterencode( self, o, markers = None ):
          if isinstance( o, ObjectId ):
               return """ObjectId("%s")""" % str(o)
          else:
               return JSONEncoder._iterencode(self, o, markers)

错误:413请求实体太大

我试图增加upload_max_filesize对20M使用Edit PHP FPM Configuration和Edit PHP CLI Configuration在Laravel锻造工具.它成功保存了我的设置,但更改似乎没有生效.我试过重启nginx和服务器.

环境:

• AWS EC2
• nginx的

我在这个查询中使用了多个运算符.我没有语法错误,但我没有得到任何数据(应该是),所以我很确定我正在查看逻辑错误.问题是,我没有看到它.

查询:

db.questions.find(
    {'$and': [
        {'answers.s_user_id': {'$ne': s_user_id}},
        {'$or': [
                {'s_text': re.compile(s_term, re.IGNORECASE)},
