用户使用表单django在登录页面上选择语言 [英] User selects language on login page using form django

问题描述

我有一个具有以下表单的登录页面：

 < form class =login-formname = LoginFormaction ={％url'login'％}method =post> 
 {％csrf_token％} 
< p> 
< table> 
< tr> 
< td> {{form.username.label_tag}}< / td> 
< td> {{form.username}}< / td> 
< / tr> 
< tr> 
< td> {{form.password.label_tag}}< / td> 
< td> {{form.password}}< / td> 
< / tr> 
< / table> 
< / p> 
< input class =button button-smalltype =submitvalue =Login/> 
< input type =hiddenname =nextvalue ={{next}}/> 
< / form> 
< a>英文< / a> 
< a>法语< / a> 
  

我有一个如下的forms.py：

$来自django.contrib.auth.forms导入的
$ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $


$ b username = forms.CharField（label =Username，max_length = 30，
widget = forms.TextInput（attrs = {'class'：'form-control'，'name'：'username'}）
password = forms.CharField（label =Password，max_length = 30，
widget = forms.TextInput（attrs = {'type'：'password'，'name'：'password' class'：'form-control'}））

和urls.py看起来像这样：来自django.contrib的url
从django导入admin

 从django.conf.urls导入包含。 contrib.auth导入视图作为auth_views 
从stellar.forms import LoginForm 
从stellar.views import index2 
 from django.conf .urls.i18n import i18n_patterns 
 urlpatterns = [
 url（r'^ admin /'，admin.site.urls），
 url（r'^'，include（'example.urls '）），
 url（r'^ login / $'，auth_views.login，{'template_name'：'login.html'，'authentication_form'：LoginForm}，name ='login'），
 url（r'^ logout / $'，auth_views.logout，{'next_page'：'/ login'}），
 url（r'^ i18n /'，include（'django.conf.urls.i18n '）），
] 
  

基本上，如果用户点击英语或法语，的页面应该改变。如何执行此操作？

解决方案

您应该在认证方式之下创建另一个表单，如这个。

  {％load i18n％} 
 
< form action ={％url'set_language'％}method =post > {％csrf_token％} 
 
 ... 
  

按照说明从那里，你会很好！

让我知道如果这样工作。

I have a login page with the following form:

  <form class="login-form" name="LoginForm" action="{% url 'login' %}" method="post">
  {% csrf_token %}
    <p>
        <table>
            <tr>
                <td>{{ form.username.label_tag }} </td>
                <td>{{ form.username }}</td>
            </tr>
            <tr>
                <td>{{ form.password.label_tag }}</td>
                <td>{{ form.password }}</td>
            </tr>
        </table>
    </p>
    <input class="button button-small" type="submit" value="Login" />
    <input type="hidden" name="next" value="{{ next }}" />
  </form>
  <a>English</a>
  <a>French</a>

and I have a forms.py that looks like this:

from django.contrib.auth.forms import AuthenticationForm 
from django import forms

class LoginForm(AuthenticationForm):
    username = forms.CharField(label="Username", max_length=30, 
                               widget=forms.TextInput(attrs={'class': 'form-control', 'name': 'username'}))
    password = forms.CharField(label="Password", max_length=30, 
                               widget=forms.TextInput(attrs={'type': 'password', 'name': 'password', 'class': 'form-control'}))

and urls.py that looks like this:

from django.conf.urls import include, url
from django.contrib import admin
from django.contrib.auth import views as auth_views
from stellar.forms import LoginForm
from stellar.views import index2
from django.conf.urls.i18n import i18n_patterns
urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^', include('example.urls')),
    url(r'^login/$', auth_views.login, {'template_name': 'login.html', 'authentication_form': LoginForm}, name = 'login'),
    url(r'^logout/$', auth_views.logout, {'next_page': '/login'}),
    url(r'^i18n/', include('django.conf.urls.i18n')),
]

Basically, if the user clicks on English or French the language of the page should change. How do I go about doing this?

解决方案

You should make another form below the authenticated one like this.

{% load i18n %}

<form action="{% url 'set_language' %}" method="post">{% csrf_token %}

...

Follow the instructions from there and you'll be fine!

Let me know if that worked.
