大家好，我是天空之城，今天給大家?guī)?lái)小福利，django搭建個(gè)人網(wǎng)站的源碼公開（一）
**django框架的原理：**它采用的是MVT架構(gòu)，m就是model數(shù)據(jù)模型，就是數(shù)據(jù)的結(jié)構(gòu)和字段，比如是個(gè)人博客數(shù)據(jù)，就需要定義title和content數(shù)據(jù)類型，其他的表格之類的也需要定義相應(yīng)的數(shù)據(jù)類型；v就是views就是視圖也就是控制中心，所有網(wǎng)頁(yè)顯示的內(nèi)容都需要在這里用函數(shù)來(lái)定義，包括從數(shù)據(jù)庫(kù)中調(diào)用數(shù)據(jù)；t就是template模塊，就是你要展示的具體網(wǎng)頁(yè)內(nèi)容html語(yǔ)言和css語(yǔ)言，這就是大體的框架，另外還要放一些static靜態(tài)文件，比如圖片，js文件之類。
當(dāng)你拿到一個(gè)django文件首先需要看一下數(shù)據(jù)庫(kù)配置，你先啟動(dòng)mysql數(shù)據(jù)庫(kù)并建立相應(yīng)的數(shù)據(jù)庫(kù)名稱，再進(jìn)行數(shù)據(jù)庫(kù)文件的遷移

python manage.py makemigrations python manage.py migrate創(chuàng)建網(wǎng)站后臺(tái)用戶名和密碼 python manage.py createsuperuser

首先是項(xiàng)目目錄截圖

其次是視圖views文件

這里每定義的一個(gè)函數(shù)就代表返回一個(gè)網(wǎng)頁(yè) from django.shortcuts import render# Create your views here.from django.http import HttpResponsedef zhuye(request):return HttpResponse("天空之城是帥哥")def indexfunc(request):return render(request,'myapp/index2.html')from .models import Students def students(request):studentsList= Students.stuObj2.all()return render(request,'myapp/students.html',{'students':studentsList})from .models import Grades def grades(request):gradesList=Grades.graObj2.all()return render(request,'myapp/grades.html',{'grades':gradesList})def addstudent(request):grade=Grades.graObj2.get(pk=1)stu=Students.createStudent("霍燕",18,True,"我叫霍燕",grade,"2020/07/20","2020/07/21")stu.save()return HttpResponse("我是釹")def addstudent2(request):grade=Grades.graObj2.get(pk=1)stu=Students.stuObj2.createStudent("黃奕",20,True,"我叫劉詩(shī)",grade,"2020/07/20","2020/07/21")stu.save()return HttpResponse("我是澀")def student3(request):studentsList=Students.stuObj2.all()[0:5]return render(request,'myapp/students.html',{'students':studentsList})def stupage(request,page):page=int(page)studentsList = Students.stuObj2.all()[(page-1)*5:page*5]return render(request, 'myapp/students.html', {'students': studentsList})from django.db.models import Max,Mindef studentsearch(request):# studentsList = Students. stu0bj2. filter(sname__ .contains= “孫")# studentsList = Students. stu0bj2. filter(sname_ startswith= "孫")# studentsList = Students. stuobj2. filter(pk_ in=[2, 4, 6, 8, 10])# studentsList = Students. stu0bj2. filter(sage_ gt=30)# studentsList = Students. stuobj2. filter(lastTime__ year=2017)studentsList = Students.stuObj2.filter(sname__contains="劉")maxAge=Students.stuObj2.aggregate(Max('sage'))print(maxAge)return render(request,'myApp/students.html',{'students': studentsList})from django.db.models import F,Qdef grades1(request):g=Grades.graObj2.filter(ggirlnum__gt=F('gboynum'))print(g)return HttpResponse("你牛")def get1(request):a=request.GET.get('a')b = request.GET['b']c = request.GET.get('c')return HttpResponse(a+" "+ b +" "+c)def get2(request):a = request.GET.getlist('a')a1=a[0]a2=a[1]c = request.GET.get('c')return HttpResponse(a1 + " " + a2 + " " + c)def showregist(request):return render(request, 'myapp/regist.html', )def regist(request):name = request.POST.get("name")gender = request.POST.get("gender")age = request.POST.get("age")hobby = request.POST.getlist("hobby")print(name)print(gender)print(age)print(hobby)return HttpResponse("regist")from django.http import HttpResponseRedirect from django.shortcuts import redirect def redirect1(request):# return HttpResponseRedirect('/redirect2')return redirect('/redirect2') def redirect2(request):return HttpResponse("我是重定向后的視圖")def main(request):# 取sessionusername = request.session.get('name', '游客')print(username)return render(request, 'myapp/main.html', {'username': username})def login(request):return render(request, 'myapp/login.html')def showmain(request):print("*****************")username = request.POST.get('username')# 存儲(chǔ)sessionrequest.session['name'] = usernamereturn redirect('/main/')from django.contrib.auth import logout def quit(request):# 清除sessionlogout(request) #

然后是model數(shù)據(jù)模型文件

from django.db import models# Create your models here.from django.db import modelsclass GradesManager(models.Manager):def get_querset(self):return super(GradesManager,self).get_queryset().filter(isDelete=False)class Grades(models.Model):#graObj=models.Manager()graObj2=GradesManager()gname = models.CharField(max_length=20)gdate = models.DateTimeField()ggirlnum = models.IntegerField()gboynum = models.IntegerField()isDelete = models.BooleanField(default=False)def __str__(self):return self.gnameclass Meta:db_table='grades'class StudentsManager(models.Manager):def get_querset(self):return super(StudentsManager,self).get_queryset().filter(isDelete=False)def createStudent(self, name, age, gender, contend,grade, lastT, createT, isD=False):stu=self.model()# print(type(grade))stu.sname=namestu.sage=agestu.sgender=genderstu.scontend=contendstu.sgrade=gradestu.lastTime=lastTstu.createTime=createTreturn stuclass Students(models.Model):#stuObj=models.Manager()stuObj2=StudentsManager()sname = models.CharField(max_length=20)sgender = models.BooleanField(default=True)sage = models.IntegerField()scontend = models.CharField(max_length=20)lastTime = models.DateTimeField(auto_now=True)createTime = models.DateTimeField(auto_now_add=True)isDelete = models.BooleanField(default=False)sgrade = models.ForeignKey("Grades", on_delete=models.CASCADE, )def __str__(self):return self.snameclass Meta:db_table='students'ordering=["id"]@classmethoddef createStudent(cls, name, age, gender, contend,grade, lastT, createT, isD=False):stu = cls(sname=name,sage=age,sgender=gender,scontend=contend,sgrade=grade,lastTime=lastT,createTime=createT,isDelete=isD)return stufrom tinymce.models import HTMLField class Text(models.Model):str = HTMLField()from django.db import models from mdeditor.fields import MDTextField class Blog(models.Model):title = models.CharField(max_length=100)content = MDTextField()# class TempTables(models.Model): # a=models.BooleanField(default=True)

然后是admin里面的文件，要注冊(cè)你定義的類

from django.contrib import admin# Register your models here. from .models import Text admin.site.register(Text)from django.contrib import admin from .models import Blog# Register your models here.@admin.register(Blog) class BlogAdmin(admin.ModelAdmin):list_display = ['title','content']

接下來(lái)是項(xiàng)目下面的主目錄project/urls路由文件，和app下面的app/urls路由文件，這個(gè)是控制你的網(wǎng)頁(yè)URL地址的

"""project URL ConfigurationThe `urlpatterns` list routes URLs to views. For more information please see:https://docs.djangoproject.com/en/3.0/topics/http/urls/ Examples: Function views1. Add an import: from my_app import views2. Add a URL to urlpatterns: path('', views.home, name='home') Class-based views1. Add an import: from other_app.views import Home2.

最后是settings文件

""" Django settings for project project.Generated by 'django-admin startproject' using Django 3.0.4.For more information on this file, see https://docs.djangoproject.com/en/3.0/topics/settings/For the full list of settings and their values, see https://docs.djangoproject.com/en/3.0/ref/settings/ """import os# Build paths inside the project like this: os.path.join(BASE_DIR, ...)

還有project/__init__文件，需要定義一下數(shù)據(jù)庫(kù)

blog網(wǎng)頁(yè)簡(jiǎn)單代碼

好了以上就是整個(gè)django項(xiàng)目的源碼
