BBS论坛项目

1、项目开发流程

1、互联网项目(产品经理提需求),传统行业项目(客户提需求)
2、项目开发流程
   需求分析(组长，项目经理，产品经理)
   原型设计(产品经理)
   美工UI切图
   设计程序，数据库(上面两个可以跟设计数据库同步操作)
   分任务开发(张三写用户相关，李四写订单相关)，多人协同开发(git，svn)
   假设过了三个月所有任务开发完了
   测试(专门的测试)
   上线
3、项目开发模式
   瀑布模式
   敏捷开发

2、博客项目需求

多人博客
博客首页
登录: 图片验证码
注册: 上传头像
自己有自己的个人站点(根据分类，标签，时间，过滤文章)
自己的后台管理
	发表博客(富文本编辑器，xss攻击处理)
	查看，删除
文章分类
随笔档案
文章标签
文章
文章详情
评论(根评论，子评论)
点赞点踩

3、bbs项目表设计

# 表设计(8张)
1、用户表: UserInfo表
2、博客表: Blog表
3、分类表: Category
4、标签表: Tag
5、文章: Article(文章和详情一个表)
6、评论: Comment
7、点赞点踩表: UpAndDown
8、文章标签中间表
    
# 表中字段
1、用户表: UserInfo表（通过继承auth_user扩展）
	phone
	avatar(头像)
    blog(关联字段)
    
2、博客表: Blog表
	title
    name
    style
    
3、分类表: Category
	name

4、标签表: Tag
	name
	blog
	
5、文章: Article(文章和详情一个表)
	title
    desc
    content
    create_time
    blog
    category
    tag(多对多)

6、评论: Comment
	user
    article
    create_time
    content
    
7、点赞点踩表: UpAndDown
	user
    article
    is_up
    create_time

4、数据库表创建及同步

models.py

from django.db import models

from django.contrib.auth.models import AbstractUser


class UserInfo(AbstractUser):
    phone = models.CharField(max_length=32, verbose_name='手机号')
    # upload_to文件上传以后存放的路径
    # FileField本质是varchar类型
    avator = models.FileField(upload_to='avator/', default='avator/default.png')
    blog = models.OneToOneField(to='Blog', on_delete=models.CASCADE, null=True)


class Blog(models.Model):
    title = models.CharField(max_length=32, verbose_name='博客标题')
    name = models.CharField(max_length=32, verbose_name='博客描述')
    style = models.CharField(max_length=32, verbose_name='博客样式')


class Tag(models.Model):
    name = models.CharField(max_length=32, verbose_name='标签名称')
    blog = models.ForeignKey(to='Blog', on_delete=models.CASCADE)


class Category(models.Model):
    name = models.CharField(max_length=32, verbose_name='分类名称')
    blog = models.ForeignKey(to='Blog', on_delete=models.CASCADE)


class Article(models.Model):
    title = models.CharField(max_length=32, verbose_name='文章标题')
    desc = models.CharField(max_length=128, verbose_name='文章描述')
    content = models.TextField(verbose_name='文章内容')
    create_time = models.DateTimeField(auto_now_add=True, verbose_name='文章创建时间')

    # 关联字段
    blog = models.ForeignKey(to='Blog', on_delete=models.CASCADE)
    category = models.ForeignKey(to='Category', on_delete=models.CASCADE)
    tag = models.ManyToManyField(to='Tag', through='TagToArticle', through_fields=('article', 'tag'))


class TagToArticle(models.Model):
    tag = models.ForeignKey(to='Tag', on_delete=models.CASCADE)
    article = models.ForeignKey(to='Article', on_delete=models.CASCADE)


class UpAndDown(models.Model):
    user = models.ForeignKey(to='UserInfo', on_delete=models.CASCADE)
    article = models.ForeignKey(to='Article', on_delete=models.CASCADE)
    is_up = models.BooleanField(verbose_name='是否是点赞')
    create_time = models.DateTimeField(auto_now_add=True, verbose_name='点赞点踩创建时间')


class Comment(models.Model):
    user = models.ForeignKey(to='UserInfo', on_delete=models.CASCADE)
    article = models.ForeignKey(to='Article', on_delete=models.CASCADE)
    content = models.CharField(max_length=255, verbose_name='评论内容')
    create_time = models.DateTimeField(auto_now_add=True, verbose_name='评论创建时间')
    # 存父评论的id号
    comments = models.ForeignKey(to='self', on_delete=models.CASCADE)

执行迁移文件的两条命令

python manage.py makemigrations
python manage.py migrate

5、注册

5.1、注册form组件

blog_forms.py

from django import forms
from django.forms import widgets

from blog.models import UserInfo


class BlogForm(forms.Form):
    username = forms.CharField(min_length=3, max_length=18, required=True, label='用户名',
                               error_messages={'min_length': '最小为3位', 'max_length': '最大为18位', 'required': '该字段必填'},
                               widget=widgets.TextInput(attrs={'class': 'form-control'}))

    password = forms.CharField(min_length=3, max_length=18, required=True, label='密码',
                               error_messages={'min_length': '最小为3位', 'max_length': '最大为18位', 'required': '该字段必填'},
                               widget=widgets.PasswordInput(attrs={'class': 'form-control'}))

    re_password = forms.CharField(min_length=3, max_length=18, required=True, label='确认密码',
                                  error_messages={'min_length': '最小为3位', 'max_length': '最大为18位', 'required': '该字段必填'},
                                  widget=widgets.PasswordInput(attrs={'class': 'form-control'}))

    email = forms.EmailField(required=True, label='邮箱',
                             error_messages={'min_length': '最小为3位', 'max_length': '最大为18位', 'required': '该字段必填',
                                             'invalid': '邮箱不合法'},
                             widget=widgets.TextInput(attrs={'class': 'form-control'}))

    def clean_username(self):
        username = self.cleaned_data.get('username')
        count = UserInfo.objects.filter(username=username).count()
        if count:
            self.add_error('username', '用户名已存在')
        else:
            return username

    def clean(self):
        pwd = self.cleaned_data.get('password')
        re_pwd = self.cleaned_data.get('re_password')
        if pwd == re_pwd:
            return self.cleaned_data
        else:
            self.add_error('re_password', '两次密码输入不一致')

setting中配置媒体资源

# 由于FileField会自动保存文件，所以默认以MEDIA_ROOT开始往下找，如果没有配，默认以根路径开始
# 以后上传的文件，都是从media路径往下找
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')

    var filereader = new FileReader();
    // 把图片读到filereader对象中
    filereader.readAsDataURL($(this)[0].files[0]);
    // 文件完全读到文件阅读器以后再执行
    filereader.onload = function () {
        $('#img').attr('src', filereader.result);
    }
});

5.4、注册路由配置

总路由

path('blog/', include(('blog.urls','blog'), namespace='blog')),

blog路由

path('register/', views.Register.as_view(), name='register'),
path('login/', views.Login.as_view(), name='login'),

5.5、注册功能视图

from django.shortcuts import render, HttpResponse
from django.http import JsonResponse
from django.views import View
from blog.blog_forms import BlogForm
from blog.models import UserInfo

class Register(View):
    def get(self, request, *args, **kwargs):
        forms = BlogForm()
        return render(request, 'register.html', context={'forms': forms})

    def post(self, request, *args, **kwargs):
        res = {'code': 100, 'msg': 'success'}
        forms = BlogForm(request.POST)
        if forms.is_valid():
            data = forms.cleaned_data
            data.pop('re_password')
            files = request.FILES.get('avator')
            if files:
                data['avator'] = files
            UserInfo.objects.create_user(**data)
            res['url'] = '/blog/login/'
            return JsonResponse(res)
        else:
            res['code'] = 101
            res['msg'] = '数据验证失败'
            res['error'] = forms.errors
            return JsonResponse(res)

5.6、注册功能错误渲染

// 提交数据
$('#id_submit').on('click', function () {
    var formdata = new FormData();
    formdata.append('avator', $('#id_myfile')[0].files[0]);
    res = $('#id_form').serializeArray();
    $.each(res, function (key, value) {
        formdata.append(value['name'], value['value'])
    });

    $.ajax({
        url: '',
        method: 'post',
        data: formdata,
        processData: false,
        contentType: false,
        success: function (data) {
            if (data.code == 100) {
                console.log(data.msg);
                location.href = data.url;
            } else {
                $.each(data.error, function (key, value) {
                    $('#id_' + key).next('span').text(value[0]).parent().addClass('has-error')
                });
				// 过3秒钟，错误信息清除，在匿名函数中执行
                setTimeout(function () {
                    $('.text-danger').text('').parent().removeClass('has-error')
                }, 3000);
            }
        }
    })
});

5.7、用户名变化校验

5.7.1、视图函数

def check_username(request):
    res = {'code': 100, 'msg': None}
    if request.is_ajax():
        username = request.POST.get('username')
        count = UserInfo.objects.filter(username=username).first()
        if count:
            res['code'] = 102
            res['msg'] = '该用户已存在'
    return JsonResponse(res)

5.7.2、用户名变化前端校验

// 检测用户名是否存在
// 当光标不再username控件上就发送ajax请求，去后台查询
$('#id_username').on('blur', function () {
    var _this = $(this);
    $.ajax({
        url: '/blog/check_username/',
        method: 'post',
        data: {
            'username': $('#id_username').val(),
            'csrfmiddlewaretoken': $("[name='csrfmiddlewaretoken']").val()
        },
        success: function (data) {
            if (data !== 100) {
                _this.next('span').html(data.msg);
            }
        }
    })
});

9、admin后台管理

# 路由
path('admin/', admin.site.urls),

# admin.py中注册
from django.contrib import admin
from blog import models
admin.site.register(models.UserInfo)
admin.site.register(models.Article)
admin.site.register(models.Blog)
admin.site.register(models.Category)
admin.site.register(models.UpAndDown)
admin.site.register(models.Comment)
admin.site.register(models.Tag)
admin.site.register(models.TagToArticle)

# setting中配置国际化
LANGUAGE_CODE = 'zh-hans'
TIME_ZONE = 'Asia/Shanghai'
USE_I18N = True
USE_L10N = True
USE_TZ = False

# 表名显示中文
class Meta:
    verbose_name_plural='标签表'
# 数据显示中文
def __str__(self):
   return self.name

10、media及头像显示

1、用户上传的头像能够在浏览器中访问到
2、默认情况下,static下的都能访问
3、media文件夹下的图片不能访问,需要手动打开
4、使用方式
	项目根路径下新建media文件夹
    setting中配置MEDIA_ROOT=os.path.join(BASE_DIR,'media')
    路由中配置:
    from django.urls import re_path
	from django.views.static import serve
	from django.conf import settings
    re_path('^media/(?P.*)$', serve,{'document_root': settings.MEDIA_ROOT}),

11、个人站点文章显示

11.1、路由

# 个人站点 访问tag/category/achive
re_path(r'^my_site/(?P\w+)/(?Ptag|category|achive)/(?P.*).html$', views.my_site,name='my_site'),
re_path(r'^my_site/(?P\w+)/', views.my_site, name='my_site'),

11.2、视图函数

def my_site(request, name, **kwargs):
    obj = UserInfo.objects.filter(username=name).first()
    if obj:

        article_list = models.Article.objects.filter(blog__userinfo__username=name)

        query = kwargs.get('query', None)
        if query == 'category':
            condition = kwargs.get('condition')
            article_list = article_list.filter(category_id=condition)
        elif query == 'tag':
            condition = kwargs.get('condition')
            article_list = article_list.filter(tagtoarticle__tag_id=condition)
        elif query == 'achive':
            year, month = kwargs.get('condition').split('/')
            article_list = article_list.filter(create_time__year=year, create_time__month=month)
