python+django+sql学生信息管理后台开发
一、功能
实现对学生对个人信息的增删查改
实现后台对所有学生信息的操作
二、平台
windows+pycharm（python开发工具）
三、逻辑框图
四、代码展示
此后台采用的是MVC的风格模式进行编码
1.VIEWS部分
def hello(request):#功能选择
# t = loader.get_template("hello.html")
# c = RequestContext(request)
return render_to_response("hello.html",context_instance=RequestContext(request))
def addstu(request):# 添加学生信息
name = request.POST.get("name")
age = request.POST.get("age")
learn = request.POST.get("learn")
newstu = Student(name=name,age=age,learn=learn)
newstu.save()
# c = RequestContext(request)
# t = loader.get_template("check.html")
return render_to_response("done.html",context_instance=RequestContext(request,{"age":age,"learn":learn,"name":name}))
def checkstu(request):#查询学生信息
find = []
stulist = Student.objects.all()
name = request.POST.get("name")
age = request.POST.get("age")
learn = request.POST.get("learn")
if name:
find = Student.objects.filter(name__contains=name)
elif age:
find = Student.objects.filter(age=age)
elif age:
find = Student.objects.filter(learn__contains=learn)
return render_to_response("check.html",context_instance=RequestContext(request,{"stulist":stulist,"find":find}))
def putmessage(request):#信息提交中转
return render_to_response("add.html",context_instance=RequestContext(request))
def deletStu(request):#删除学生信息
alert=""
name = request.POST.get("name")
age = request.POST.get("age")
learn = request.POST.get("learn")
delet = request.POST.get("delet")
find = Student.objects.filter(name__contains =name)
if not find:
alert = u"没有找到名为" + name + u"的学生"
elif not delet:
elert=""
else:
find.delete()
alert = u"成功删除该学生"
return render_to_response("delet.html",context_instance=RequestContext(request,{"alert":alert,"student":find}))
def putmessage2(request):#信息提交中转2
return render_to_response("put2.html",context_instance=RequestContext(request))
def rewrite(request):#学生信息更改
aler=u"提示："
stulist = Student.objects.all()
message = request.POST.get("message")
old = request.POST.get("old")
new = request.POST.get("new")
if old == "name":
student= Student.objects.filter( name__contains = message).update(name = new)
aler+=u"信息修改成功"
elif old== "age":
student= Student.objects.filter( name__contains = message).update(age = new)
aler+=u"信息修改成功"
elif old =="learn":
student= Student.objects.filter( name__contains = message).update(learn = new)
aler+=u"信息修改成功"
else:
aler+=u"请输入正确的需要修改的信息类别（name，age或learn）"
return render_to_response("show.html",context_instance=RequestContext(request,{"id":id,"message":message,"new":new,"stulist":stulist,"aler":aler}))
2.MODELS 部分
class Student(models.Model):#学生模板
name = models.CharField(max_length=20)
age = models.IntegerField()
learn = models.CharField(max_length=20)
def __unicode__(self):
return self.name
class Teacher(models.Model):#老师模板
name = models.CharField(max_length=20)
age = models.IntegerField()
teach = models.CharField(max_length=20)
student = models.ManyToManyField( Student,through = "OneClass")
def __unicode__(self):
return self.name
class OneClass(models.Model):#班级模板
name = models.CharField(max_length=50)
teacher = models.ForeignKey(Teacher)
student = models.ForeignKey(Student)
def __unicode__(self):
return self.name
3.CONTROLLER部分
URL配置
urlpatterns = [url(r'^blog/','blog.views.hello'),
url(r'^adstu/','blog.views.addstu'),
url(r'^add/','blog.views.putmessage'),
url(r'^check/','blog.views.checkstu'),
url(r'^readydel/','blog.views.putmessage2'),
url(r'^delet/','blog.views.deletStu'),
url(r'^show/','blog.views.rewrite'),
url(r'^admin/', include(admin.site.urls)),]
表单的设置
__author__ = 'deven'
from django import forms
class ContentForm(forms.Form):
username = forms.CharField()#max_length = 20)
password = forms.IntegerField()#max_value= 20)
五、功能展示
1.主界面（功能选择）
2.增加学生信息
3.查询学生信息
4.删除学生信息
5.更改学生信息
