小编Tam*_*mpa的帖子

我正在使用upstart为生成的nginx python fastcgi脚本创建一个守护进程.如果我使用下面的工作:

sudo start myserver

什么不起作用是:

sudo stop myserver
stop: Unknown instance:

下面是我的conf文件,其中包含停止进程的命令.我假设杀死hte proccess的命令是在停止前脚本？

#!upstart
description "myserver"
author      "Test"

start on startup
stop on shutdown
respawn
#instance

script
    export HOME="/root"

    echo $$ > /var/run/myerver.pid
    exec spawn-fcgi -d /home/ubuntu/workspace/rtbopsConfig/myserver/ -f /home/ubuntu/workspace/rtbopsConfig/myserver/index.py -a 127.0.0.1 -p 9001 >> /var/log/myserver.sys.log 2>&1
end script

pre-start script
    # Date format same as (new Date()).toISOString() for consistency
    echo "[`date -u +%Y-%m-%dT%T.%3NZ`] (sys) Starting" >> /var/log/myserver.sys.log

这是我如何转储文件

with open('es_hosts.json', 'w') as fp:
  json.dump(','.join(host_list.keys()), fp)

结果是

 "a,b,c"

我想要:

 a,b,c

谢谢

我将此代码转换为最新的Angular 2. authentication.service.ts

代码应该是什么样的？

app/auth/auth.service.ts(30,40): error TS7006: Parameter 'u' implicitly has an 'any' type.

// services/auth.service.ts
import {Injectable} from '@angular/core';
import {Router} from '@angular/router';

export class User {
  constructor(
    public email: string,
    public password: string) { }
}

var users:any = [
  new User('admin@admin.com','adm9'),
  new User('user1@gmail.com','a23')
];

@Injectable()
export class AuthenticationService {

  constructor(
    private _router: Router){}

  logout() {
    localStorage.removeItem("user");
    this._router.navigate(['Login']);
  }

  login(user:any){
    var authenticatedUser = users.find(u => u.email === user.email);
    if (authenticatedUser){
      localStorage.setItem("user", authenticatedUser);
      this._router.navigate(['Home']);      
      return true;
    } …

我有一个基于以下输入框:

如果更改收音机,我会看到该值对于false更改为true:

<pre> {{model_parameters_general.estimationmethod=='ew'}} </pre>

那么哇为什么输入框会因为false而被禁用？

<input [disabled]="model_parameters_general.estimationmethod=='ew'" [(ngModel)]="model_parameters_general.lambda" 
                           formControlName="lambda" type="text" class="form-control">

编辑:

在日志中,我得到了这个:

It looks like you're using the disabled attribute with a reactive form directive. If you set disabled to true
      when you set up this control in your component class, the disabled attribute will actually be set in the DOM for
      you. We recommend using this approach to avoid 'changed after checked' errors.

  Example: 
  form = new FormGroup({
    first: new FormControl({value: 'Nancy', disabled: true}, Validators.required),
    last: new …

我正在使用angular-cli with angular2 v4.0 with angular material.

伙计......所有的错误都是什么？我正在努力学习业力,如果我运行npm测试,我会得到34个与材料相关的失败...例如

Can't bind to 'routerLinkActive' since it isn't a known property of 'a'
Can't bind to 'md-menu-trigger-for' since it isn't a known property of 'button'
Can't bind to 'md-menu-trigger-for' since it isn't a known property of 'button'

If 'md-menu' is an Angular component, then verify that it is part of this module.

等等

如何使角度物质与业力相得益彰？

我的应用程序工作正常,但如果达到业力......将是一场彻底的灾难.

谢谢

我有很多!app.module.ts文件中的@NgModule中的声明,entryComponents,导入和提供程序.看来我必须在我的dashboard.component.spec.ts文件中添加每一个.我一个接一个地添加,并没有变得愚蠢.我真的不想添加不相关的组件.我怎样才能导入app.module.ts文件？我有50多个要导入...

这是我得到的错误类型:

这是我的canDeactivate防护装置，它有效。但是，当我使用“提交”按钮时，我不想叫守卫。仅当我通过任何其他方式导航时。怎么样？

import { Injectable } from '@angular/core';
import { Router, CanDeactivate } from '@angular/router';
import { FormGroup } from '@angular/forms';

export interface FormComponent {
    myForm: FormGroup;
}

@Injectable()
export class DirtyGuard implements CanDeactivate<FormComponent>  {
  constructor(private router: Router) {}

  canDeactivate(component: FormComponent) {
      console.log(component.myForm)
        if (component.myForm.dirty ){
            return confirm('You have unsaved changes. Are you sure you want to navigate away?');
        }
        return true;
  }
}
