访问表单中的数据

Question

我在我的模板中有一个用于搜索的表单。我没有为它创建任何表单类。是否可以在视图中访问表单数据，或者我应该为其创建表单类。

<form class="navbar-form" role="search" action="{% url 'my_url_name' %}" method="get">
 <div class="input-group add-on">
  <input class="form-control" placeholder="search" name="srch-term" id="srch-term" type="text">
  <div class="input-group-btn">
    <button class="btn btn-default" type="submit"><i class="glyphicon glyphicon-search"></i></button>
  </div>
</div>
</form>

我使用此表单作为其样式，我无法使用Form类

创建此样式

Answer 1

您可以在视图中的request.GET（或request.POST，如果它是一个帖子请求）词典中访问表单数据。例如：

srch_term = request.GET.get('srch-term')

Answer 2

您可以使用请求获得的QueryDict对象：

import { NgModule } from '@angular/core';
import { IonicApp, IonicModule } from 'ionic-angular';
import { Camera } from 'ionic-native';
import { Http, XSRFStrategy, CookieXSRFStrategy  } from '@angular/http';
import { Storage  } from '@ionic/storage';
import { FormsModule }   from '@angular/forms';
import { MyApp } from './app.component';
import { AboutPage } from '../pages/about/about';
import { HomePage } from '../pages/home/home';
import { TabsPage } from '../pages/tabs/tabs';
import { LoginPage } from '../pages/login/login';
import { PhotoPage } from '../pages/photo/photo';
import { AboutPage } from '../pages/about/about';
import { GalleryPage } from '../pages/gallery/gallery';
import { SubmittedPage } from '../pages/submitted/submitted';
import { PhotoPage } from '../pages/photo/photo';
import { ResetPasswordPage } from '../pages/reset-password/reset-password';
import { SignupPage } from '../pages/signup/signup';
import { DjangoAuth } from '../providers/djangoAuth';
import { ImageData } from '../providers/imageData';

@NgModule({
  declarations: [
    MyApp,
    AboutPage,
    HomePage,
    TabsPage,
    LoginPage,
    PhotoPage,
    GalleryPage,
    SubmittedPage,
    ResetPasswordPage,
    SignupPage
  ],
  imports: [
    IonicModule.forRoot(MyApp, [
      Http,
      DjangoAuth,
      ImageData,
      FormsModule,
      {provide:XSRFStrategy, useValue: new CookieXSRFStrategy('csrftoken', 'X-CSRFToken')}])
  ],
  bootstrap: [IonicApp],
  entryComponents: [
    MyApp,
    AboutPage,
    HomePage,
    TabsPage,
    LoginPage,
    PhotoPage,
    GalleryPage,
    SubmittedPage,
    ResetPasswordPage,
    SignupPage
  ],
  providers: [
    DjangoAuth,
    ImageData,
    Storage,
    Camera
  ]
})

export class AppModule {}

但请注意：没有验证工具可以确保您收到的数据格式正确。
