djngo快速實現--使用Bootstrap

繼續django學習之旅，之前我們所做的Django練習前端都非常丑。這節我們使用Bootstrap，頓時使丑陋的頁面變成白天鵝。

 

 

安裝Bootstrap                                      

 

Bootstrap是什么？

Bootstrap是Twitter推出的一個用於前端開發的開源工具包。它由Twitter的設計師Mark Otto和Jacob Thornton合作開發，是一個CSS/HTML框架。Bootstrap提供了優雅的HTML和CSS規范，它即是由動態CSS語言Less寫成。

 

django-bootstrap-toolkit

django-bootstrap-toolkit應用可以讓Django非容易的集成Bootstrap。

 

 

安裝django-bootstrap-toolkit

 

>pip install django-bootstrap-toolkit

 

 

 

 

運行bootstrap例子                                   

 

 

克隆django-bootstrap-toolkit 項目

https://github.com/dyve/django-bootstrap-toolkit

 

$ git clone git://github.com/dyve/django-bootstrap-toolkit.git

  

克隆下來的django-bootstrap-toolkit 項目自帶demo_project，現在我們可以直接運行這個demo了。

進入demo_project 目錄運行：

> python manage.py runserver

 

通過瀏覽器訪問：http://127.0.0.1:8000/

wa o !! cool 比我們之前的djngo例子好看多了。

 

 

 

 

預覽demo_project                                                                       

 

來看一下這個項目的結構吧！

通過前面多個django項目練習，我們已經對這個目錄結構不陌生了。下面看看這個例子要特別注意的：

 

settings.py

 

……
INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    # Uncomment the next line to enable the admin:
    # 'django.contrib.admin',
    # Uncomment the next line to enable admin documentation:
    # 'django.contrib.admindocs',
    'bootstrap_toolkit', 'demo_app', )
……

 

要想使用bootstrap，這里必須加載bootstrap_toolkit ，demo_app則是我們當前的項目。

 

urls.py

from django.conf.urls import patterns, url

# Uncomment the next two lines to enable the admin:
# from django.contrib import admin
# admin.autodiscover()
from django.views.generic import TemplateView

urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'demo_project.views.home', name='home'),
    # url(r'^demo_project/', include('demo_project.foo.urls')),

    # Uncomment the admin/doc line below to enable admin documentation:
    # url(r'^admin/doc/', include('django.contrib.admindocs.urls')),

    # Uncomment the next line to enable the admin:
    # url(r'^admin/', include(admin.site.urls)),

    url(r'^$', TemplateView.as_view(template_name='index.html'), name="home"),
    url(r'^contact$', TemplateView.as_view(template_name='contact.html'), name="contact"),
    url(r'^form$', 'demo_app.views.demo_form'),
    url(r'^form_template$', 'demo_app.views.demo_form_with_template'),
    url(r'^form_inline$', 'demo_app.views.demo_form_inline'),
    url(r'^formset$', 'demo_app.views.demo_formset', {}, "formset"),
    url(r'^tabs$', 'demo_app.views.demo_tabs', {}, "tabs"),
    url(r'^pagination$', 'demo_app.views.demo_pagination', {}, "pagination"),
    url(r'^widgets$', 'demo_app.views.demo_widgets', {}, "widgets"),
    url(r'^buttons$', TemplateView.as_view(template_name='buttons.html'), name="buttons"),
)

 

 

下面再看看views.py寫了哪些中間邏輯：

from django.contrib import messages
from django.forms.formsets import formset_factory
from django.shortcuts import render_to_response
from django.template.context import RequestContext
from django.core.paginator import Paginator, PageNotAnInteger, EmptyPage

from bootstrap_toolkit.widgets import BootstrapUneditableInput

from .forms import TestForm, TestModelForm, TestInlineForm, WidgetsForm, FormSetInlineForm


def demo_form_with_template(request):
    layout = request.GET.get('layout')
    if not layout:
        layout = 'vertical'
    if request.method == 'POST':
        form = TestForm(request.POST)
        form.is_valid()
    else:
        form = TestForm()
    modelform = TestModelForm()
    return render_to_response('form_using_template.html', RequestContext(request, {
        'form': form,
        'layout': layout,
    }))

def demo_form(request):
    messages.success(request, 'I am a success message.')
    layout = request.GET.get('layout')
    if not layout:
        layout = 'vertical'
    if request.method == 'POST':
        form = TestForm(request.POST)
        form.is_valid()
    else:
        form = TestForm()
    form.fields['title'].widget = BootstrapUneditableInput()
    return render_to_response('form.html', RequestContext(request, {
        'form': form,
        'layout': layout,
    }))

def demo_form_inline(request):
    layout = request.GET.get('layout', '')
    if layout != 'search':
        layout = 'inline'
    form = TestInlineForm()
    return render_to_response('form_inline.html', RequestContext(request, {
        'form': form,
        'layout': layout,
    }))


def demo_formset(request):
    layout = request.GET.get('layout')
    if not layout:
        layout = 'inline'
    DemoFormSet = formset_factory(FormSetInlineForm)
    if request.method == 'POST':
        formset = DemoFormSet(request.POST, request.FILES)
        formset.is_valid()
    else:
        formset = DemoFormSet()
    return render_to_response('formset.html', RequestContext(request, {
        'formset': formset,
        'layout': layout,
    }))


def demo_tabs(request):
    layout = request.GET.get('layout')
    if not layout:
        layout = 'tabs'
    tabs = [
        {
            'link': "#",
            'title': 'Tab 1',
            },
        {
            'link': "#",
            'title': 'Tab 2',
            }
    ]
    return render_to_response('tabs.html', RequestContext(request, {
        'tabs': tabs,
        'layout': layout,
    }))


def demo_pagination(request):
    lines = []
    for i in range(10000):
        lines.append(u'Line %s' % (i + 1))
    paginator = Paginator(lines, 10)
    page = request.GET.get('page')
    try:
        show_lines = paginator.page(page)
    except PageNotAnInteger:
        # If page is not an integer, deliver first page.
        show_lines = paginator.page(1)
    except EmptyPage:
        # If page is out of range (e.g. 9999), deliver last page of results.
        show_lines = paginator.page(paginator.num_pages)
    return render_to_response('pagination.html', RequestContext(request, {
        'lines': show_lines,
    }))


def demo_widgets(request):
    layout = request.GET.get('layout', 'vertical')
    form = WidgetsForm()
    return render_to_response('form.html', RequestContext(request, {
        'form': form,
        'layout': layout,
    }))

 

剩下的就是模板目錄templates 了，里面的html模板頁面較多，我就不一一列出了。不過，現在最興奮的就是去修改上面的文字，讓其看起來更像我們自己的“網站”。

　　在后面的學習中，我們將以此為基礎進行。
