djngo快速实现--使用Bootstrap
继续django学习之旅，之前我们所做的Django练习前端都非常丑。这节我们使用Bootstrap，顿时使丑陋的页面变成白天鹅。
安装Bootstrap
Bootstrap是什么？
Bootstrap是Twitter推出的一个用于前端开发的开源工具包。它由Twitter的设计师Mark Otto和Jacob Thornton合作开发，是一个CSS/HTML框架。Bootstrap提供了优雅的HTML和CSS规范，它即是由动态CSS语言Less写成。
django-bootstrap-toolkit
django-bootstrap-toolkit应用可以让Django非容易的集成Bootstrap。
安装django-bootstrap-toolkit
>pip install django-bootstrap-toolkit
运行bootstrap例子
克隆django-bootstrap-toolkit 项目
https://github.com/dyve/django-bootstrap-toolkit
$ git clone git://github.com/dyve/django-bootstrap-toolkit.git
克隆下来的django-bootstrap-toolkit 项目自带demo_project，现在我们可以直接运行这个demo了。
进入demo_project 目录运行：
> python manage.py runserver
通过浏览器访问：http://127.0.0.1:8000/
wa o !! cool 比我们之前的djngo例子好看多了。
预览demo_project
来看一下这个项目的结构吧！
通过前面多个django项目练习，我们已经对这个目录结构不陌生了。下面看看这个例子要特别注意的：
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，这里必须加载bootstrap_toolkit ，demo_app则是我们当前的项目。
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写了哪些中间逻辑：
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,}))
剩下的就是模板目录templates 了，里面的html模板页面较多，我就不一一列出了。不过，现在最兴奋的就是去修改上面的文字，让其看起来更像我们自己的“网站”。
在后面的学习中，我们将以此为基础进行。
