如何為 Django 項目添加多語言支持

Django 提供開箱即用的多語言支持。事實上,Django 被翻譯成 100 多種語言。本教程著眼於如何為您的 Django 項目添加多語言支持。

目標

在本教程結束時,您應該能夠:

  1. 解釋國際化和本地化的區別
  2. 為 URL 添加語言前綴
  3. 翻譯模板
  4. 允許用戶在語言之間切換
  5. 翻譯模型
  6. 添加語言環境支持

項目設置

下面是您將要構建的應用程序的快速瀏覽:

示例應用

它可能看起來很簡單,但它會讓您對向 Django 添加國際化感到滿意。

首先,從django-lang存儲庫中克隆基礎分支:

$ git clone https://github.com/Samuel-2626/django-lang --branch base --single-branch
$ cd django-lang

接下來,創建並激活一個虛擬環境,安裝項目的依賴項,應用遷移,並創建一個超級用戶:

$ python3.9 -m venv env
$ source env/bin/activate

(env)$ pip install -r requirements.txt
(env)$ python manage.py makemigrations
(env)$ python manage.py migrate
(env)$ python manage.py createsuperuser

隨意將 virtualenv 和 Pip 換成PoetryPipenv。有關更多信息,請查看現代 Python 環境

記下course/models.pyCourse中的模型:

from django.db import models

class Course(models.Model):
    title = models.CharField(max_length=90)
    description = models.TextField()
    date = models.DateField()
    price = models.DecimalField(max_digits=10, decimal_places=2)

    def __str__(self):
        return self.title

運行以下管理命令將一些數據添加到您的數據庫中:

$ python manage.py add_courses

在下一節中,我們將簡要介紹國際化和本地化。

國際化與本地化

國際化和本地化代表同一枚硬幣的兩個方面。它們一起允許您將 Web 應用程序的內容交付到不同的語言環境。

  • 國際化,由 i18n 表示(18 是 i 和 n 之間的字母數),是開發應用程序的過程,以便它可以被不同的語言環境使用。此過程通常由開發人員處理。
  • 另一方面,由 l10n 表示的本地化(10 是 l 和 n 之間的字母數)是將應用程序翻譯成特定語言和區域設置的過程這通常由翻譯人員處理。

有關更多信息,請查看W3C 的本地化與國際化。

回想一下,Django 通過其國際化框架已被翻譯成100多種語言:

通過國際化框架,我們可以輕鬆地在 Python 代碼和模板中標記要翻譯的字符串。它利用 GNU gettext工具包來生成和管理一個純文本文件,該文件代表一種稱為消息文件的語言。消息文件以.po作為其擴展名結尾。翻譯完成後會為每種語言生成另一個文件,該文件以.mo擴展名結尾。這稱為編譯翻譯。

讓我們從安裝gettext工具包開始。

在 macOS 上,建議使用Homebrew

$ brew install gettext
$ brew link --force gettext

對於大多數 Linux 發行版,它是預先安裝的。最後,對於 Windows,可以在此處找到安裝步驟。

在下一節中,我們將為國際化和本地化準備 Django 項目。

Django 的國際化框架

Django 在settings.py文件中帶有一些默認的國際化設置:

# Internationalization
# https://docs.djangoproject.com/en/3.1/topics/i18n/

LANGUAGE_CODE = 'en-us'

TIME_ZONE = 'UTC'

USE_I18N = True

USE_L10N = True

USE_TZ = True

第一個設置是LANGUAGE_CODE. 默認情況下,它設置為美國英語 (en-us)。這是特定於語言環境的名稱。讓我們將其更新為通用名稱 English (en)。

LANGUAGE_CODE = 'en'

有關更多信息,請參閱語言標識符列表

要使LANGUAGE_CODE生效,USE_I18N必須是True,這會啟用 Django 的翻譯系統。

記下其餘設置:

TIME_ZONE = 'UTC'

USE_L10N = True

USE_TZ = True

筆記:

  1. 'UTC' 是默認的TIME_ZONE
  2. 由於USE_L10N設置為True,Django 將使用當前語言環境的格式顯示數字和日期。
  3. 最後,當USE_TZ為時True,日期時間將是時區感知的。

讓我們添加一些額外的設置來補充現有的設置:

from django.utils.translation import gettext_lazy as _

LANGUAGES = (
    ('en', _('English')),
    ('fr', _('French')),
    ('es', _('Spanish')),
)

這裡發生了什麼事?

  1. 我們指定了我們希望我們的項目可用的語言。如果沒有指定,Django 將假定我們的項目應該在其所有支持的語言中可用。
  2. LANGUAGE設置由語言代碼和語言名稱組成。回想一下,語言代碼可以是特定於語言環境的,例如“en-gb”,也可以是通用的,例如“en”。
  3. 此外,gettext_lazy用於翻譯語言名稱而不是gettext防止循環導入。當您在全局範圍內時,您幾乎應該總是使用gettext_lazy 。

添加django.middleware.locale.LocaleMiddlewareMIDDLEWARE設置列表。這個中間件應該放在後面,SessionMiddleware因為LocaleMiddleware需要使用會話數據。它也應該放在前面,CommonMiddleware因為CommonMiddleware需要活動語言來解析被請求的 URL。因此,順序非常重要。

MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.locale.LocaleMiddleware', # new
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
]

該中間件用於根據請求數據確定當前語言。

為您的應用程序添加一個區域設置路徑目錄,其中將駐留消息文件:

LOCALE_PATHS = [
    BASE_DIR / 'locale/',
]

Django 查看翻譯文件的LOCALE_PATHS設置。請記住,首先出現的語言環境路徑具有最高優先級。

您需要在根項目中創建“locale”目錄並為每種語言添加一個新文件夾:

locale
├── en
├── es
└── fr

打開 shell 並從項目目錄運行以下命令,為每種語言創建一個.po消息文件:

(env)$ django-admin makemessages --all --ignore=env

你現在應該有:

locale
├── en
│   └── LC_MESSAGES
│       └── django.po
├── es
│   └── LC_MESSAGES
│       └── django.po
└── fr
    └── LC_MESSAGES
        └── django.po

記下.po消息文件之一:

  1. msgid: 表示出現在源代碼中的翻譯字符串。
  2. msgstr: 表示語言翻譯,默認為空。您必須提供任何給定字符串的實際翻譯。

目前,只有LANGUAGES來自我們的settings.py文件已被標記為翻譯。因此,對於msgstr“fr”和“es”目錄下的每個,分別手動輸入該單詞的法語或西班牙語等效項。您可以從常規代碼編輯器編輯.po文件;但是,建議使用專門為.po設計的編輯器,例如Poedit

對於本教程,進行以下更改:

# locale/fr/LC_MESSAGES/django.po

msgid "English"
msgstr "Anglais"

msgid "French"
msgstr "Français"

msgid "Spanish"
msgstr "Espagnol"


# locale/es/LC_MESSAGES/django.po

msgid "English"
msgstr "Inglés"

msgid "French"
msgstr "Francés"

msgid "Spanish"
msgstr "Español"

Poedit 示例:

Poedit 示例

接下來,讓我們通過運行以下命令來編譯消息:

(env)$ django-admin compilemessages --ignore=env

已為每種語言生成了一個.mo編譯的消息文件:

locale
├── en
│   └── LC_MESSAGES
│       ├── django.mo
│       └── django.po
├── es
│   └── LC_MESSAGES
│       ├── django.mo
│       └── django.po
└── fr
    └── LC_MESSAGES
        ├── django.mo
        └── django.po

--

這就是本節的內容!

到目前為止,您已經介紹了很多內容,讓我們先回顧一下,然後再討論其他概念。回想一下,本教程的目標是教您如何為 Django 項目添加多語言支持。在第一部分中,您設置了項目並查看了您將要構建的內容。然後,您了解了國際化和本地化之間的區別以及 Django 國際化框架如何在幕後工作。最後,我們將項目配置為允許多語言支持並看到它的實際效果:

  1. 為我們的 Django 項目添加了國際化
  2. 設置我們希望項目可用的語言
  3. 通過生成消息文件gettext_lazy
  4. 手動添加翻譯
  5. 編譯了翻譯

翻譯模板、模型和表格

您可以通過使用gettextorgettext_lazy函數將模型字段名稱和表單標記為要翻譯來翻譯它們:

像這樣編輯course/models.py文件:

from django.db import models
from django.utils.translation import gettext_lazy as _

class Course(models.Model):
    title = models.CharField(_('title'), max_length=90)
    description = models.TextField(_('description'))
    date = models.DateField(_('date'))
    price = models.DecimalField(_('price'), max_digits=10, decimal_places=2)

    def __str__(self):
        return self.title
(env)$ django-admin makemessages --all --ignore=env

隨意msgstr手動或使用 Poedit 界面更新法語和西班牙語的翻譯,然後編譯消息

(env)$ django-admin compilemessages --ignore=env

我們也可以通過添加標籤來為表單執行此操作。

例如:

from django import forms
from django.utils.translation import gettext_lazy as _

class ExampleForm(forms.Form):
    first_name = forms.CharField(label=_('first name'))

為了翻譯我們的模板,Django 提供了{% trans %}{% blocktrans %}模板標籤來翻譯字符串。您必須{% load i18n %}在 HTML 文件的頂部添加才能使用翻譯模板標籤。

模板標籤允許您標記要翻譯的{% trans %}文字。Django 只是在內部對給定文本執行gettext函數。

{% trans %}標記對於簡單的翻譯字符串很有用,但它不能處理包含變量的翻譯內容。

{% blocktrans %}另一方面,模板標籤允許您標記包含文字和變量的內容。

更新course/templates/index.html文件中的以下元素以查看其實際效果:

<h1>{% trans "TestDriven.io Courses" %}</h1>

不要忘記添加{% load i18n %}到文件的頂部。

(env)$ django-admin makemessages --all --ignore=env

更新以下msgstr翻譯:

# locale/fr/LC_MESSAGES/django.po

msgid "TestDriven.io Courses"
msgstr "Cours TestDriven.io"


# locale/es/LC_MESSAGES/django.po

msgid "TestDriven.io Courses"
msgstr "Cursos de TestDriven.io"

編譯消息:

(env)$ django-admin compilemessages --ignore=env

使用 Rosetta 翻譯接口

我們將使用一個名為Rosetta的第三方庫來編輯翻譯,使用與 Django 管理站點相同的界面。它使編輯.po文件變得容易,並為您自動更新編譯的翻譯文件。

Rosetta 已作為依賴項的一部分安裝;因此,您需要做的就是將其添加到已安裝的應用程序中:

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'course.apps.CourseConfig',
    'rosetta',  # NEW
]

您還需要將 Rosetta 的 URL 添加到django_lang/urls.py中的主 URL 配置中:

urlpatterns = [
    path('admin/', admin.site.urls),
    path('rosetta/', include('rosetta.urls')),  # NEW
    path('', include('course.urls')),
]

創建並應用遷移,然後運行服務器:

(env)$ python manage.py makemigrations
(env)$ python manage.py migrate
(env)$ python manage.py runserver

確保您以管理員身份登錄,然後在瀏覽器中導航到http://127.0.0.1:8000/rosetta/ :

羅塞塔主頁

在項目下,單擊每個應用程序以編輯翻譯。

羅塞塔法語

完成編輯翻譯後,單擊“保存並翻譯下一個塊”按鈕將翻譯保存到各自的.po文件中。Rosetta 隨後將編譯消息文件,因此無需手動運行該django-admin compilemessages --ignore=env命令。

請注意,在生產環境中添加新翻譯後,您必須在運行django-admin compilemessages --ignore=env命令後或使用 Rosetta 保存翻譯後重新加載服務器,才能使更改生效。

為 URL 添加語言前綴

使用 Django 的國際化框架,您可以在不同的 URL 擴展名下為每個語言版本提供服務。例如,您的網站的英文版本可以在 下提供/en/,法語版本可以在 下提供/fr/,等等。這種方法使網站針對搜索引擎進行了優化,因為每個 URL 都將為每種語言編制索引,這反過來又會為每種語言提供更好的排名。為此,Django 國際化框架需要從請求的 URL 中識別當前語言;因此,LocalMiddleware需要在MIDDLEWARE您的項目設置中添加,我們已經完成了。

接下來,將i18n_patterns函數添加到django_lang/urls.py

from django.conf.urls.i18n import i18n_patterns
from django.contrib import admin
from django.urls import path, include
from django.utils.translation import gettext_lazy as _

urlpatterns = i18n_patterns(
    path(_('admin/'), admin.site.urls),
    path('rosetta/', include('rosetta.urls')),
    path('', include('course.urls')),
)

再次運行開發服務器,並在瀏覽器中導航到http://127.0.0.1:8000/ 。您將被重定向到請求的 URL,並帶有適當的語言前綴。查看瀏覽器中的 URL;它現在應該看起來像http://127.0.0.1:8000/en/

將請求的 URL 從 更改enfres。標題應該改變。

使用 django-parler 翻譯模型

Django 的國際化框架不支持開箱即用地翻譯模型,因此我們將使用一個名為django-parler的第三方庫。有許多插件可以執行此功能;但是,這是最受歡迎的之一。

它是如何工作的?

django-parler 將為每個包含翻譯的模型創建一個單獨的數據庫表。此表包括所有已翻譯的字段。它還具有鏈接到原始對象的外鍵。

django-parler 已作為依賴項的一部分安裝,因此只需將其添加到已安裝的應用程序中:

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'course.apps.CourseConfig',
    'rosetta',
    'parler',  # NEW
]

此外,將以下代碼添加到您的設置中:

PARLER_LANGUAGES = {
    None: (
        {'code': 'en',}, # English
        {'code': 'fr',}, # French
        {'code': 'es',}, # Spanish
    ),
    'default': {
        'fallbacks': ['en'],
        'hide_untranslated': False,
    }
}

在這裡,您為 django-parler 定義了可用的語言(英語、法語、西班牙語)。您還將英語指定為默認語言,並指出 django-parler 不應隱藏未翻譯的內容

要知道什麼?

  1. django-parler 提供了一個TranslatableModel模型類和一個TranslatedFields包裝器來翻譯模型字段。
  2. django-parler 通過為每個可翻譯模型生成另一個模型來管理翻譯。

請注意,因為 Django 使用單獨的表進行翻譯,所以會有一些 Django 功能是您無法使用的。此外,此遷移將刪除數據庫中以前的記錄。

再次更新course/models.py看起來像這樣:

from django.db import models
from parler.models import TranslatableModel, TranslatedFields


class Course(TranslatableModel):
    translations = TranslatedFields(
        title=models.CharField(max_length=90),
        description=models.TextField(),
        date=models.DateField(),
        price=models.DecimalField(max_digits=10, decimal_places=2),
    )

    def __str__(self):
        return self.title

接下來,創建遷移:

(env)$ python manage.py makemigrations

在繼續之前,請在新創建的遷移文件中替換以下行:

bases=(parler.models.TranslatedFieldsModelMixin, models.Model),

與以下一個:

bases = (parler.models.TranslatableModel, models.Model)

恰好在 django-parler 中發現了一個我們剛剛解決的小問題。如果不這樣做,將阻止應用遷移。

接下來,應用遷移:

(env)$ python manage.py migrate

django_parler 的一個很棒的特性是它可以與 Django 管理站點順利集成。它包括一個TranslatableAdmin覆蓋ModelAdminDjango 提供的類來管理翻譯的類。

像這樣編輯course/admin.py

from django.contrib import admin
from parler.admin import TranslatableAdmin

from .models import Course

admin.site.register(Course, TranslatableAdmin)

運行以下管理命令將一些數據再次添加到您的數據庫中:

(env)$ python manage.py add_courses

運行服務器,然後在瀏覽器中導航到http://127.0.0.1:8000/admin/ 。選擇其中一門課程。對於每門課程,現在可以使用每種語言的單獨字段。

Django 談話示例

請注意,我們幾乎沒有觸及 django-parler 可以為我們實現的功能。請參閱文檔以了解更多信息。

允許用戶切換語言

在本節中,我們將展示如何讓用戶能夠從我們的主頁切換語言。

像這樣更新index.html文件:

{% load i18n %}

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta http-equiv="X-UA-Compatible" content="IE=edge" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <link
      href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/css/bootstrap.min.css"
      rel="stylesheet"
      integrity="sha384-EVSTQN3/azprG1Anm3QDgpJLIm9Nao0Yz1ztcQTwFspd3yD65VohhpuuCOmLASjC"
      crossorigin="anonymous"
    />
    <title>TestDriven.io</title>
      <style>
        h1, h3 {
          color: #266150;
        }
        li {
          display: inline;
          text-decoration: none;
          padding: 5px;
        }
        a {
          text-decoration: none;
          color: #DDAF94;
        }
        a:hover {
          color: #4F4846;
        }
        .active {
          background-color: #266150;
          padding: 5px;
          text-align: right;
          border-radius: 7px;
        }
      </style>
  </head>
  <body>
    <div class="container">
      <h1>{% trans "TestDriven.io Courses" %}</h1>

      {% get_current_language as CURRENT_LANGUAGE %}
      {% get_available_languages as AVAILABLE_LANGUAGES %}
      {% get_language_info_list for AVAILABLE_LANGUAGES as languages %}
      <div class="languages">
        <p>{% trans "Language" %}:</p>
        <ul class="languages">
          {% for language in languages %}
            <li>
              <a href="/{{ language.code }}/"
                {% if language.code == CURRENT_LANGUAGE %} class="active"{% endif %}>
                {{ language.name_local }}
              </a>
            </li>
          {% endfor %}
        </ul>
      </div>

      {% for course in courses %}
        <div class="card p-4">
          <h3>
            {{ course.title }}
            <em style="font-size: small">{{ course.date }}</em>
          </h3>
          <p>{{ course.description }}</p>
          <strong>Price: $ {{ course.price }}</strong>
        </div>
        <hr />
      {% empty %}
        <p>Database is empty</p>
      {% endfor %}

    </div>
  </body>
</html>

這裡發生了什麼事?

我們:

  1. 使用 . 加載國際化標籤{% load i18n %}
  2. {% get_current_language %}使用標籤檢索當前語言。
  3. 還通過模板標籤獲得了LANGUAGES設置中定義的可用語言。{% get_available_languages %}
  4. 然後使用{% get_language_info_list %}標籤啟用語言屬性。
  5. 構建了一個 HTML 列表來顯示所有可用的語言,並為當前活動的語言添加了一個活動類屬性以突出顯示活動的語言。

在瀏覽器中導航到http://127.0.0.1:8000/以查看更改。在多種語言之間切換,並註意每種語言的 URL 前綴如何變化。

添加語言環境支持

還記得我們是如何設置USE_L10NTrue嗎?這樣,只要在模板中輸出值,Django 就會嘗試使用特定於語言環境的格式。因此,日期、時間和數字將根據用戶的語言環境採用不同的格式。

在瀏覽器中導航回http://127.0.0.1:8000/以查看更改,您會注意到日期格式發生了變化。您網站的英文版本中的小數位數以小數點分隔符顯示,而在西班牙文和法文版本中,它們使用逗號顯示。這是由於每種語言之間的區域設置格式不同。

示例應用

結論

在本教程中,您了解了國際化和本地化以及如何通過 Django 的國際化框架配置 Django 項目以進行國際化。我們還使用 Rosetta 來簡化消息文件的更新和編譯,並使用 django-parler 來翻譯我們的模型。

How model queries work in Django

How model queries work in Django

Welcome to my blog, hey everyone in this article we are going to be working with queries in Django so for any web app that you build your going to want to write a query so you can retrieve information from your database so in this article I’ll be showing you all the different ways that you can write queries and it should cover about 90% of the cases that you’ll have when you’re writing your code the other 10% depend on your specific use case you may have to get more complicated but for the most part what I cover in this article should be able to help you so let’s start with the model that I have I’ve already created it.

**Read More : **How to make Chatbot in Python.

Read More : Django Admin Full Customization step by step

let’s just get into this diagram that I made so in here:

django queries aboutDescribe each parameter in Django querset

we’re making a simple query for the myModel table so we want to pull out all the information in the database so we have this variable which is gonna hold a return value and we have our myModel models so this is simply the myModel model name so whatever you named your model just make sure you specify that and we’re gonna access the objects attribute once we get that object’s attribute we can simply use the all method and this will return all the information in the database so we’re gonna start with all and then we will go into getting single items filtering that data and go to our command prompt.

Here and we’ll actually start making our queries from here to do this let’s just go ahead and run** Python manage.py shell** and I am in my project file so make sure you’re in there when you start and what this does is it gives us an interactive shell to actually start working with our data so this is a lot like the Python shell but because we did manage.py it allows us to do things a Django way and actually query our database now open up the command prompt and let’s go ahead and start making our first queries.

Main Pros and Cons of Django As A Web Framework for Python Developers

Django depicts itself as “the web system for fussbudgets with cutoff times”. It was intended to help Python engineers take applications from idea to consummation as fast as could be expected under the circumstances.

It permits fast turn of events on the off chance that you need to make a CRUD application with batteries included. With Django, you won’t need to rehash an already solved problem. It just works and lets you center around your business rationale and making something clients can utilize.

Pros of Django

“Batteries included” theory

The standard behind batteries-included methods normal usefulness for building web applications accompanies the system, not as isolated libraries.

Django incorporates much usefulness you can use to deal with normal web advancement undertakings. Here are some significant level functionalities that Django gives you, which else you need to stay together if you somehow happened to utilize a small scale structure:

ORM

Database relocations

Client validation

Administrator board

Structures

Normalized structure

Django as a system proposes the right structure of an undertaking. That structure helps designers in making sense of how and where to execute any new component.

With a generally acknowledged venture structure that is like numerous tasks, it is a lot simpler to discover online good arrangements or approach the network for help. There are numerous energetic Python designers who will assist you with comprehending any issue you may experience.

Django applications

Django applications (or applications for short) permit designers to separate a task into numerous applications. An application is whatever is introduced by putting in settings.INSTALLED_APPS. This makes it simpler for engineers to add usefulness to the web application by coordinating outer Django applications into the venture.

There are many reusable modules and applications to accelerate your turn of events learn through Online Django Class and Check the Django website.

Secure of course

Django gives great security assurance out of the crate and incorporates avoidance components for basic assaults like SQL Injection (XSS) and Cross-site Request Forgery (CSRF). You can discover more subtleties in the official security diagram control.

REST structure for building APIs

Django REST Framework, commonly condensed “DRF”, is a Python library for building APIs. It has secluded and adaptable engineering that functions admirably for both straightforward and complex web APIs.

DRF gives a lot of verification and authorization strategies out of the case. It is an adaptable, full-included library with measured and adjustable engineering. It accompanies nonexclusive classes for CRUD tasks and an implicit API program for testing API endpoints.

GraphQL structure for building APIs

Huge REST APIs regularly require a lot of solicitations to various endpoints to recover every single required datum. GraphQL it’s a question language that permits us to share related information in a lot simpler design. For a prologue to GraphQL and an outline of its ideas, if it’s not too much trouble allude to the authority GraphQL documentation.

Graphene-Django gives reflections that make it simple to add GraphQL usefulness to your Django venture. Ordinary Django models, structures, validation, consent arrangements, and different functionalities can be reused to manufacture GraphQL blueprint. It additionally gives an implicit API program for testing API endpoints.

Cons of Django

Django ORM
