django-groundwork
本文也是看了网络上的一些django文章后弄出，加上自己个人的一点心得和想法。
django-groundwork可以为一个app里面的model的添加 增删 的功能，以下是在django1.7的版本下部署，网络上也有一些是一些过去1.4之类的部署。
django1.7的部署，在github上下载后，把该文件夹放在项目下，和app，manage.py同级。然后在setting.py上的INSTALLED_APPS添加进去，很简单。
之后可以python manage.py help查看是否加入了新的命令 groundwork。
确定后运行python manage.py app modelname
其中modelname 就是你在app里面的需要添加功能的models名字。
运行命令后输出Y确定执行。会在app里面生成新的views，urls，forms文件，template会生成界面。
url.py里面会显示错误，记得加入from django.conf.urls import patterns。
app/urls.py
from django.conf.urls import patterns
from models import *
from views import *
urlpatterns = patterns('',
(r'product/create/$', create_product),
(r'product/list/$', list_product ),
(r'product/edit/(?P<id>[^/]+)/$', edit_product),
(r'product/view/(?P<id>[^/]+)/$', view_product),
)
最后两个url的里面后部分是正则表达式，意思是会接受id的，他会get来自网页的参数，参数会赋给id，之后会传递给views里面的对应的def，经过对应的函数后return回去给网页。
在setting.py的文件夹里面的url可以在里面加入app文件夹的url。
记得在setting里面加入
TEMPLATE_DIRS = (
'templates',
)
不然会显示读取不到template。
from django.conf.urls import patterns, include, url
from django.contrib import admin
urlpatterns = patterns('',
# Examples:
# url(r'^$', 'depot.views.home', name='home'),
# url(r'^blog/', include('blog.urls')),
url(r'^admin/', include(admin.site.urls)),
url(r'^prodect/',include('depotapp.urls')),
)
app/views.py
def create_product(request):
form = ProductForm(request.POST or None)
if form.is_valid():
form.save()
form = ProductForm()
t = get_template('depotapp/create_product.html')
c = RequestContext(request,locals())
return HttpResponse(t.render(c))
def list_product(request):
list_items = Product.objects.all()
paginator = Paginator(list_items ,10)
try:
page = int(request.GET.get('page', '1'))
except ValueError:
page = 1
try:
list_items = paginator.page(page)
except :
list_items = paginator.page(paginator.num_pages)
t = get_template('depotapp/list_product.html')
c = RequestContext(request,locals())
return HttpResponse(t.render(c))
def view_product(request, id):
product_instance = Product.objects.get(id = id)
t=get_template('depotapp/view_product.html')
c=RequestContext(request,locals())
return HttpResponse(t.render(c))
def edit_product(request, id):
product_instance = Product.objects.get(id=id)
form = ProductForm(request.POST or None, instance = product_instance)
if form.is_valid():
form.save()
t=get_template('depotapp/edit_product.html')
c=RequestContext(request,locals())
return HttpResponse(t.render(c))
app/forms.py
class ProductForm(forms.ModelForm): class Meta: model = Product # exclude = [] # uncomment this line and specify any field to exclude it from the form def __init__(self, *args, **kwargs): super(ProductForm, self).__init__(*args, **kwargs)
django-groundwork帮我们生成这么多打码，逻辑不难看懂，我是一个django入门级别的，可以学到很多。
