繼續(xù)django學習之旅，之前我們所做的Django練習前端都非常丑。這節(jié)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推出的一個用于前端開發(fā)的開源工具包。它由Twitter的設計師Mark?Otto和Jacob?Thornton合作開發(fā)，是一個CSS/HTML框架。Bootstrap提供了優(yōu)雅的HTML和CSS規(guī)范，它即是由動態(tài)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(xiàn)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(jié)構(gòu)吧！

通過前面多個django項目練習，我們已經(jīng)對這個目錄結(jié)構(gòu)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 TemplateViewurlpatterns = 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, EmptyPagefrom bootstrap_toolkit.widgets import BootstrapUneditableInputfrom .forms import TestForm, TestModelForm, TestInlineForm, WidgetsForm, FormSetInlineFormdef 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(xiàn)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(wǎng)站”。

　　在后面的學習中，我們將以此為基礎進行。
