我正在使用Angular 6和scraperjs.

在我的组件文件中,使用了示例中给出的代码

import { Component, OnInit } from '@angular/core';

import scraperjs from 'scraperjs';

@Component({
  selector: 'app-express',
  templateUrl: './express.component.html',
  styleUrls: ['./express.component.css']
})
export class ExpressComponent implements OnInit {

  constructor() { }

  ngOnInit() {
    this.aliExpress();
  }

  aliExpress() {
    console.log('loaded ali express');

    scrapperjs.StaticScraper.create('https://news.ycombinator.com')
      .scrape(function ($) {
        return $('.title a').map(function () {
          return $(this).text();
        }).get();
      }).then(function (news) {
      console.log(news);
    });
  }

}

但它给出了错误

Failed to compile.

我正在使用Angular 6.

我通过扩展NbgPopover声明了一个指令StickyPopover并添加了*app.module.ts**declaration

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppRoutingModule } from './app-routing.module';

我正在设置Docker来运行我的CakePHP应用程序，我的Dockerfile就像

我正在使用Angular 7

我有一个嵌套的反应形式

this.salonProfileForm = this.fb.group({
  salonName: new FormControl('', [Validators.required]),
  address: this.fb.group({
    city: new FormControl('', [Validators.required])
  })
});

get f() {
    return this.salonProfileForm.controls;
}

我有这样的 HTML 表单

<input type="text" formControlName="salonName" required />
<ng-container *ngIf="submitted && f.salonName.invalid && (f.salonName.dirty || f.salonName.touched)">
   <small *ngIf="f.salonName.errors.required">
      Salon name is required
   </small>
</ng-container>

<div formGroupName="address">
  <input type="text" formControlName="city" />
  <ng-container *ngIf="submitted && f.city.invalid && (f.city.dirty || f.city.touched)">
    <small *ngIf="f.city.errors.required">
        city is required
    </small>
  </ng-container>
</div>

但这会在城市输入ng-container字段上产生错误，如下所示

我正在使用 sphinx 来记录我的 Django 应用程序。

我有以下文档目录结构

docs
|- build

   |- _static
   |- _templates
   |- conf.py
   |- index.rst
   |- upgrade.rst
|- upgrade_changes
   |- migration
      |- index.rst
   |- index.rst
   |- library_changes.rst

和内容docs/source/index.rst是

My App's documentation!
=============================================
App Description

Revamp Upgrade Changes

   upgrade

该source/upgrade.rst文件包含来自upgrade_changes

.. include:: ../upgrade_changes/index.rst

并且/upgrade_changes/index.rst有

Following is the list of all revamp related documentation.

我想为与.oslibrary_changes.rst文件处于同一级别的文件包含一个目录树index.rst。 …

我用nginx的是代理服务器。我的应用程序有一个功能，用户可以使用自己的域而不是我的域。为此，他们需要将其 CNAME 指向我的域。

这是我的 Nginx 配置

server {
  server_name                   scan.mydomain.com anonymous.mydomain.com "";
  access_log                    /etc/nginx/log/local-wc.access.log;
  error_log                     /etc/nginx/log/local-wc.error.log;

  location / {
    root                      /var/www/html/qcg-scanning-frontend/dist/webapp/;

我正在Django 1.11中编写应用程序。

myapp/urls.py 图案看起来像

from django.conf.urls import url, include
from django.contrib import admin
from django.contrib.auth.views import LoginView

urlpatterns = [
    url(r'^login/$', LoginView.as_view(), {'redirect_authenticated_user': True}),
    url('^', include('django.contrib.auth.urls')),
    url('^', include('pages.urls')),
    url(r'^pages/', include('pages.urls')),
    url(r'^search/', include('search.urls')),
    url(r'^admin/', admin.site.urls),
]

我想在尝试访问/login页面时重定向登录用户。为此，我已经按照此处的文档中的设置redirect_authenticated_user进行了设置True

但是，/login成功登录后访问时，它不会重定向。

我正在使用Django 2.x

我有一个像

class MyModel(models.Model):
    name = models.CharField()
    balance = models.IntegerField()

我想更改 GET 请求中的 balance 值而不更改数据库中的值。

就像它可能是@Property字段一样，模型看起来像

class MyModel(models.Model):
    name = models.CharField()
    balance = models.IntegerField()

    @property
    def balance(self):
        if balance:
           return balance
        return 0.15 * 50

但不允许重新声明。我该如何解决这个问题？

注意：字段应与ModelAdmin和DRF Serializer兼容
