组合搜索的实现
验证码与验证
需要安装Pillow模块
pip stall pillow
1、首先需要借助pillow模块用来画一个验证码图形，这里单独封装了一个py文件，调用一个方法就好了
1 #!/user/bin/env python 2 # -*-coding: utf-8-*- 3 import random 4 from PIL import ImageDraw,ImageFont,Image,ImageFilter 5 6 7 def random_check_code(width=120, height=30, char_length=5, font_file=‘wryh.ttf‘, font_size=28): 8 code = [] 9 img = Image.new(mode=‘RGB‘, size=(width, height), color=(255, 255, 255)) 10 draw = ImageDraw.Draw(img, mode=‘RGB‘) 11 12 def rndChar(): 13 """ 14 生成随机字母 15 :return: 16 """ 17 return chr(random.randint(65, 90)) 18 19 def rndColor(): 20 """ 21 生成随机颜色 22 :return: 23 """ 24 return (random.randint(0, 255), random.randint(10, 255), random.randint(64, 255)) 25 26 # 写文字 27 font = ImageFont.truetype(font_file, font_size) 28 for i in range(char_length): 29 char = rndChar() 30 code.append(char) 31 h = random.randint(0, 4) 32 draw.text([i * width / char_length, h], char, font=font, fill=rndColor()) 33 34 # 写干扰点 35 for i in range(40): 36 draw.point([random.randint(0, width), random.randint(0, height)], fill=rndColor()) 37 38 # 写干扰圆圈 39 for i in range(40): 40 draw.point([random.randint(0, width), random.randint(0, height)], fill=rndColor()) 41 x = random.randint(0, width) 42 y = random.randint(0, height) 43 draw.arc((x, y, x + 4, y + 4), 0, 90, fill=rndColor()) 44 45 # 画干扰线 46 for i in range(5): 47 x1 = random.randint(0, width) 48 y1 = random.randint(0, height) 49 x2 = random.randint(0, width) 50 y2 = random.randint(0, height) 51 draw.line((x1, y1, x2, y2), fill=rndColor()) 52 53 img = img.filter(ImageFilter.EDGE_ENHANCE_MORE) #加滤镜，可以增加颜色的不同 54 return img, ‘‘.join(code)
函数的参数都已在调用的时候修改。
2、登陆界面设计
假设验证码跟登录页面在同一函数一起生成，那么每次刷新验证码都需要整个页面一起重新加载；显然，这是不合理的。所以可以确定验证码跟登录界面是2个视图函数控制的。
1 <!DOCTYPE html> 2 <html lang="en"> 3 <head> 4 <meta charset="UTF-8"> 5 <title>Title</title> 6 </head> 7 <body style="margin: 0 auto;"> 8 <div id="main"> 9 <form method="post" action="/login/"> 10 {% csrf_token %} 11 <p><label>用户名：</label><input type="text" name="user" /></p> 12 <p><label>密码：</label><input type="password" name="pwd" /></p> 13 <p><label>验证码：</label><input type="text" name="checkcode" /><img src="/check_code.html" /></p> 14 <p><input type="submit" /></p> 15 </form> 16 </div> 17 </body> 18 </html>
1 def login(request): 2 if request.method == ‘GET‘: 3 return render(request, ‘login.html‘)
3、验证码
将验证码图片对象返回到模板
1 def check_code(request): 2 stream = BytesIO() # 申请一段内存 3 img, code = random_check_code() # 获取随机码跟随机码图片对象 4 img.save(stream, ‘PNG‘) # 将随机码对象保存到内存对象中 5 request.session[‘CheckCode‘] = code # 将随机字符串保存到session 6 return HttpResponse(stream.getvalue()) # 返回内存中的随机码图片对象
4、如何刷新验证码呢
直接将原路由系统通过点击事件赋值给src，浏览器默认是不会进行刷新的；所以这里有一个小技巧，我们可以获取src的值，在末尾加上一个？，这样就可以实现点击刷新了。
1 <!DOCTYPE html> 2 <html lang="en"> 3 <head> 4 <meta charset="UTF-8"> 5 <title>Title</title> 6 </head> 7 <body style="margin: 0 auto;"> 8 <div id="main"> 9 <form method="post" action="/login/"> 10 {% csrf_token %} 11 <p><label>用户名：</label><input type="text" name="user" /></p> 12 <p><label>密码：</label><input type="password" name="pwd" /></p> 13 <p><label>验证码：</label><input type="text" name="checkcode" /><img src="/check_code.html" onclick="ImgChange(this);"/></p> 14 <p><input type="submit" /></p> 15 </form> 16 </div> 17 </body> 18 <script> 19 function ImgChange(ths) { 20 ths.src = ths.src + ‘?‘ 21 } 22 </script> 23 </html>
开启验证码验证功能
1 def login(request): 2 if request.method == ‘GET‘: 3 return render(request, ‘login.html‘) 4 elif request.method == ‘POST‘: 5 checkcode = request.POST.get(‘checkcode‘) 6 code_session = request.session[‘CheckCode‘] 7 print(checkcode) 8 print(code_session) 9 if checkcode.upper() == request.session[‘CheckCode‘].upper(): 10 return HttpResponse(‘验证成功‘) 11 else: 12 return render(request, ‘login.html‘)
KindEditor
1、官网下载
http://kindeditor.net/demo.php
2、文件夹解压文件说明
├── asp asp示例 ├── asp.net asp.net示例 ├── attached 空文件夹，放置关联文件attached ├── examples HTML示例 ├── jsp java示例 ├── kindeditor-all-min.js 全部JS（压缩） ├── kindeditor-all.js 全部JS（未压缩） ├── kindeditor-min.js 仅KindEditor JS（压缩） ├── kindeditor.js 仅KindEditor JS（未压缩） ├── lang 支持语言 ├── license.txt License ├── php PHP示例 ├── plugins KindEditor内部使用的插件 └── themes KindEditor主题
3、基本使用
1 <!DOCTYPE html> 2 <html lang="en"> 3 <head> 4 <meta charset="UTF-8"> 5 <title>Title</title> 6 </head> 7 <body> 8 <div style="margin: 0 auto; width: 500px;height: 300px;"> 9 <textarea id="content"></textarea> 10 </div> 11 12 <script src="/static/jquery-3.2.1.js"></script> 13 <script src="/static/kindeditor/kindeditor-all-min.js"></script> 14 <script> 15 $(function() { 16 KindEditor.create("#content", { 17 width: ‘400px‘, 18 height: ‘200px‘ 19 20 }) 21 }) 22 </script> 23 </body> 24 </html>
4、详细参数
http://kindeditor.net/docs/option.html
5、上传文件示例
1 <!DOCTYPE html> 2 <html lang="en"> 3 <head> 4 <meta charset="UTF-8"> 5 <title>Title</title> 6 </head> 7 <body> 8 <form action="/upload_kind/" method="post"> 9 10 <div style="margin: 0 auto; width: 500px;height: 300px;"> 11 <textarea id="content"></textarea> 12 </div> 13 </form> 14 <script src="/static/jquery-3.2.1.js"></script> 15 <script src="/static/kindeditor/kindeditor-all-min.js"></script> 16 <script> 17 $(function() { 18 KindEditor.create("#content", { 19 width: ‘400px‘, 20 height: ‘200px‘, 21 extraFileUploadParams:{‘csrfmiddlewaretoken‘:"{{ csrf_token }}"}, 22 uploadJson:‘/upload_img/‘, 23 fileManagerJson: ‘/upload_file_manage/‘, 24 allowImageUpload: true, 25 allowFileManager:true 26 }) 27 }) 28 </script> 29 </body> 30 </html>
1 def upload_img(request): 2 f = request.FILES.get(‘imgFile‘) 3 import os 4 path = os.path.join("static/images", f.name) 5 with open(path, ‘wb‘) as file_obj: 6 for chunck in f.chunks(): 7 file_obj.write(chunck) 8 import json 9 dic = { 10 ‘error‘: 0, 11 ‘url‘: ‘/‘ + path, 12 ‘message‘: ‘错误了...‘ 13 } 14 return HttpResponse(json.dumps(dic)) 15 16 def upload_file_manage(request): 17 import os,time,json 18 dic = {} 19 root_path = ‘C:/Users/Administrator/Desktop/DownTimeAnalysis/static/‘ 20 static_root_path = ‘/static/‘ 21 request_path = request.GET.get(‘path‘) 22 if request_path: 23 abs_current_dir_path = os.path.join(root_path, request_path) 24 move_up_dir_path = os.path.dirname(request_path.rstrip(‘/‘)) 25 dic[‘moveup_dir_path‘] = move_up_dir_path + ‘/‘ if move_up_dir_path else move_up_dir_path 26 27 else: 28 abs_current_dir_path = root_path 29 dic[‘moveup_dir_path‘] = ‘‘ 30 31 dic[‘current_dir_path‘] = request_path 32 dic[‘current_url‘] = os.path.join(static_root_path, request_path) 33 34 file_list = [] 35 for item in os.listdir(abs_current_dir_path): 36 abs_item_path = os.path.join(abs_current_dir_path, item) 37 a, exts = os.path.splitext(item) 38 is_dir = os.path.isdir(abs_item_path) 39 if is_dir: 40 temp = { 41 ‘is_dir‘: True, 42 ‘has_file‘: True, 43 ‘filesize‘: 0, 44 ‘dir_path‘: ‘‘, 45 ‘is_photo‘: False, 46 ‘filetype‘: ‘‘, 47 ‘filename‘: item, 48 ‘datetime‘: time.strftime(‘%Y-%m-%d %H:%M:%S‘, time.gmtime(os.path.getctime(abs_item_path))) 49 } 50 else: 51 temp = { 52 ‘is_dir‘: False, 53 ‘has_file‘: False, 54 ‘filesize‘: os.stat(abs_item_path).st_size, 55 ‘dir_path‘: ‘‘, 56 ‘is_photo‘: True if exts.lower() in [‘.jpg‘, ‘.png‘, ‘.jpeg‘] else False, 57 ‘filetype‘: exts.lower().strip(‘.‘), 58 ‘filename‘: item, 59 ‘datetime‘: time.strftime(‘%Y-%m-%d %H:%M:%S‘, time.gmtime(os.path.getctime(abs_item_path))) 60 } 61 62 file_list.append(temp) 63 dic[‘file_list‘] = file_list 64 return HttpResponse(json.dumps(dic))
路由系统
url(r‘^kind/$‘, views.kind),
url(r‘^upload_img/‘, views.upload_img), # 前面有一个kind，视图函数可以获取参数dir来区分是文件还是其他。
url(r‘^upload_file_manage/‘, views.upload_file_manage),
6、XSS过滤特殊标签
处理依赖
pip3 install beautifulsoup4
1 #!/usr/bin/env python 2 # -*- coding:utf-8 -*- 3 from bs4 import BeautifulSoup 4 5 6 class XSSFilter(object): 7 __instance = None 8 9 def __init__(self): 10 # XSS白名单 11 self.valid_tags = { 12 "font": [‘color‘, ‘size‘, ‘face‘, ‘style‘], 13 ‘b‘: [], 14 ‘div‘: [], 15 "span": [], 16 "table": [ 17 ‘border‘, ‘cellspacing‘, ‘cellpadding‘ 18 ], 19 ‘th‘: [ 20 ‘colspan‘, ‘rowspan‘ 21 ], 22 ‘td‘: [ 23 ‘colspan‘, ‘rowspan‘ 24 ], 25 "a": [‘href‘, ‘target‘, ‘name‘], 26 "img": [‘src‘, ‘alt‘, ‘title‘], 27 ‘p‘: [ 28 ‘align‘ 29 ], 30 "pre": [‘class‘], 31 "hr": [‘class‘], 32 ‘strong‘: [] 33 } 34 35 @classmethod 36 def instance(cls): 37 if not cls.__instance: 38 obj = cls() 39 cls.__instance = obj 40 return cls.__instance 41 42 def process(self, content): 43 soup = BeautifulSoup(content, ‘lxml‘) 44 # 遍历所有HTML标签 45 for tag in soup.find_all(recursive=True): 46 # 判断标签名是否在白名单中 47 if tag.name not in self.valid_tags: 48 tag.hidden = True 49 if tag.name not in [‘html‘, ‘body‘]: 50 tag.hidden = True 51 tag.clear() 52 continue 53 # 当前标签的所有属性白名单 54 attr_rules = self.valid_tags[tag.name] 55 keys = list(tag.attrs.keys()) 56 for key in keys: 57 if key not in attr_rules: 58 del tag[key] 59 60 return soup.renderContents() 61 62 63 if __name__ == ‘__main__‘: 64 html = """<p class="title"> 65 <b>The Dormouse‘s story</b> 66 </p> 67 <p class="story"> 68 <div name=‘root‘> 69 Once upon a time there were three little sisters; and their names were 70 <a href="http://example.com/elsie" class="sister c1" style=‘color:red;background-color:green;‘ id="link1"><!-- Elsie --></a> 71 <a href="http://example.com/lacie" class="sister" id="link2">Lacie</a> and 72 <a href="http://example.com/tillie" class="sister" id="link3">Tilffffffffffffflie</a>; 73 and they lived at the bottom of a well. 74 <script>alert(123)</script> 75 </div> 76 </p> 77 <p class="story">...</p>""" 78 79 v = XSSFilter.instance().process(html) 80 print(v)
1 #!/usr/bin/env python 2 # -*- coding:utf-8 -*- 3 from bs4 import BeautifulSoup 4 5 6 class XSSFilter(object): 7 __instance = None 8 9 def __init__(self): 10 # XSS白名单 11 self.valid_tags = { 12 "font": [‘color‘, ‘size‘, ‘face‘, ‘style‘], 13 ‘b‘: [], 14 ‘div‘: [], 15 "span": [], 16 "table": [ 17 ‘border‘, ‘cellspacing‘, ‘cellpadding‘ 18 ], 19 ‘th‘: [ 20 ‘colspan‘, ‘rowspan‘ 21 ], 22 ‘td‘: [ 23 ‘colspan‘, ‘rowspan‘ 24 ], 25 "a": [‘href‘, ‘target‘, ‘name‘], 26 "img": [‘src‘, ‘alt‘, ‘title‘], 27 ‘p‘: [ 28 ‘align‘ 29 ], 30 "pre": [‘class‘], 31 "hr": [‘class‘], 32 ‘strong‘: [] 33 } 34 35 def __new__(cls, *args, **kwargs): 36 """ 37 单例模式 38 :param cls: 39 :param args: 40 :param kwargs: 41 :return: 42 """ 43 if not cls.__instance: 44 obj = object.__new__(cls, *args, **kwargs) 45 cls.__instance = obj 46 return cls.__instance 47 48 def process(self, content): 49 soup = BeautifulSoup(content, ‘lxml‘) 50 # 遍历所有HTML标签 51 for tag in soup.find_all(recursive=True): 52 # 判断标签名是否在白名单中 53 if tag.name not in self.valid_tags: 54 tag.hidden = True 55 if tag.name not in [‘html‘, ‘body‘]: 56 tag.hidden = True 57 tag.clear() 58 continue 59 # 当前标签的所有属性白名单 60 attr_rules = self.valid_tags[tag.name] 61 keys = list(tag.attrs.keys()) 62 for key in keys: 63 if key not in attr_rules: 64 del tag[key] 65 66 return soup.renderContents() 67 68 69 if __name__ == ‘__main__‘: 70 html = """<p class="title"> 71 <b>The Dormouse‘s story</b> 72 </p> 73 <p class="story"> 74 <div name=‘root‘> 75 Once upon a time there were three little sisters; and their names were 76 <a href="http://example.com/elsie" class="sister c1" style=‘color:red;background-color:green;‘ id="link1"><!-- Elsie --></a> 77 <a href="http://example.com/lacie" class="sister" id="link2">Lacie</a> and 78 <a href="http://example.com/tillie" class="sister" id="link3">Tilffffffffffffflie</a>; 79 and they lived at the bottom of a well. 80 <script>alert(123)</script> 81 </div> 82 </p> 83 <p class="story">...</p>""" 84 85 obj = XSSFilter() 86 v = obj.process(html) 87 print(v)
7、保存
直接form提交，视图函数接收对应的textarea的name就好了。
1 def upload_kind(request): 2 print(request.POST.get(‘content‘)) 3 return HttpResponse(‘ok‘)
组合搜索
大家一定对上面这张图不陌生，这就是一个很经典的组合搜索。
下面我们来做一个简单的搜索。
1 class ArticleType(models.Model): 2 caption = models.CharField(max_length=32) 3 4 5 class Category(models.Model): 6 name = models.CharField(max_length=32) 7 8 9 class Article(models.Model): 10 title = models.CharField(max_length=32) 11 content = models.CharField(max_length=255) 12 category = models.ForeignKey(to=‘Category‘) 13 article_type = models.ForeignKey(to=‘ArticleType‘)
HTML
1 def article(request, *args, **kwargs): 2 result = models.Article.objects.all() 3 return render(request, ‘article.html‘, {‘result‘:result})
去数据库补充点数据，然后就可以运行了。
先把所有的选择项列出来。
1 <h1>过滤条件</h1> 2 <div class="condition-div"> 3 <div><a>全部</a> 4 {% for row in article_type %}#} 5 <a>{{ row.caption }}</a> 6 {% endfor %}#} 7 </div> 8 <div><a>全部</a> 9 {% for row in category%}#} 10 <a>{{ row.name}}</a> 11 {% endfor %}#} 12 </div> 13 </div>
1 def article(request, *args, **kwargs): 2 article_type_list = models.ArticleType.objects.all() 3 category = models.Category.objects.all() 4 result = models.Article.objects.all() 5 return render( 6 request, 7 "article.html", 8 { 9 "result": result, 10 "article_type": article_type_list, 11 "category": category 12 } 13 )
这时候再来好好研究一下网页的逻辑
点完SUV，跳到了SUV的页面，对SUV进行删选，但是后面还有一串字符，-0-1-1等等，不难发现这是用正则做的路由参数，加上p可以固定不同的类型对应不同的位置参数。
url(r‘^article-(?P<article_type_id>\d+)-(?P<category_id>\d+).html‘, views.article),
但是，还有一个问题，比如选择了能源为汽油，又要选择座位来组合怎么做呢？
首先，需要先记录下当前的筛选参数，当然，url已经做到了，所以我们修改下URL
url(r‘^article-(?P<article_type_id>\d+)-(?P<category_id>\d+).html‘, views.article, name=‘article‘),
看到name，大家一定记起来了，这里运用到了反转，记录动态URL。先记录下url里面的参数，再把参数传递给前台，告诉前台，那么做能源筛选的时候，是不是可以直接生成一个url，记录下所有其他选择的标签的参数，再加入自身的id。上代码：
1 def article(request, *args, **kwargs): 2 # from django.urls import reverse 3 # url = reverse(‘article‘, kwargs=kwargs) 4 # print(url) # 强行带了波url的节奏，其实并不需要用到，因为url传过来的id已经被处理成字典形式了，可以区分开的。我们拿到**kwargs 5 condition = {} 6 for k, v in kwargs.items(): 7 kwargs[k] = int(v) 8 if v == ‘0‘: 9 pass 10 else: 11 condition[k] = v #这里的逻辑是因为全部这个标签，数据库的类别ID是自增的，所以设置0是最保险的。在后台把所有为0的全部过滤掉，不然会查询不到数据的。 12 article_type_list = models.ArticleType.objects.all() 13 category = models.Category.objects.all() 14 # result = models.Article.objects.filter(article_type_id=1, category_id=2) 15 result = models.Article.objects.filter(**condition) 16 return render( 17 request, 18 "article.html", 19 { 20 "result": result, 21 "article_type": article_type_list, 22 "category": category, 23 "arg_dict": kwargs, 24 } 25 )
1 <!DOCTYPE html> 2 <html lang="en"> 3 <head> 4 <meta charset="UTF-8"> 5 <title>Title</title> 6 <style> 7 .condition-div a{ 8 display: inline-block; 9 padding: 2px 3px; 10 margin: 3px 5px; 11 border: 1px solid slategrey; 12 } 13 .condition-div a.active{ 14 background-color: lightslategrey; 15 } 16 </style> 17 </head> 18 <body> 19 <h1>过滤条件</h1> 20 <div class="condition-div"> 21 <div> 22 {% if arg_dict.article_type_id == 0 %} 23 <a class="active" href="/app01/article-0-{{ arg_dict.category_id }}.html">全部</a> 24 {% else %} 25 <a href="/app01/article-0-{{ arg_dict.category_id }}.html">全部</a> 26 {% endif %} 27 {% for row in article_type %} 28 {% if row.id == arg_dict.article_type_id %} 29 <a class="active" href="/app01/article-{{ row.id }}-{{ arg_dict.category_id }}.html">{{ row.caption }}</a> 30 {% else %} 31 <a href="/app01/article-{{ row.id }}-{{ arg_dict.category_id }}.html">{{ row.caption }}</a> 32 {% endif %} 33 {% endfor %} 34 {# {% filter_article_type article_type arg_dict %}#} 35 </div> 36 <div> 37 38 {% if arg_dict.category_id == 0 %} 39 <a class="active" href="/app01/article-{{ arg_dict.article_type_id }}-0.html">全部</a> 40 {% else %} 41 <a href="/app01/article-{{ arg_dict.article_type_id }}-0.html">全部</a> 42 {% endif %} 43 {% for row in category %} 44 {% if row.id == arg_dict.category_id %} 45 <a class="active" href="/app01/article-{{ arg_dict.article_type_id }}-{{ row.id }}.html">{{ row.name }}</a> 46 {% else %} 47 <a href="/app01/article-{{ arg_dict.article_type_id }}-{{ row.id }}.html">{{ row.name }}</a> 48 {% endif %} 49 {% endfor %} 50 </div> 51 </div> 52 53 <h1>查询结果</h1> 54 <ul> 55 {% for row in result %} 56 <li>{{ row.od }} - {{ row.title }}</li> 57 {% endfor %} 58 </ul> 59 60 </body> 61 </html>
这时候基本上就已经做好了，前台html里面的if else就不具体说了，主要就是加一个active class.
现在这个前台看着太乱了，就是要强行少代码，怎么办？大家一定觉得很夸张。。。怎么减代码？？一脸懵逼，二脸懵逼，三脸懵逼。。。。。。
给大家体个醒，simple_tag，你一定会激动地叫起来，喔~~
刚好复习一下simple_tag 的制作思路，首先项目里面建一个templatetags文件夹，里面新建任意一个py文件。
1 #!/user/bin/env python 2 # -*-coding: utf-8-*- 3 from django import template 4 from django.utils.safestring import mark_safe 5 register = template.Library() 6 7 8 9 @register.simple_tag 10 def filter_all(arg_dict, k): 11 if k == ‘article_type_id‘: 12 n1 = arg_dict[‘article_type_id‘] 13 n2 = arg_dict[‘category_id‘] 14 if n1 == 0: 15 ret = ‘<a class="active" href="/app01/article-0-%s.html">全部</a>‘ % n2 16 else: 17 ret = ‘<a href="/app01/article-0-%s.html">全部</a>‘ % n2 18 else: 19 n1 = arg_dict[‘category_id‘] 20 n2 = arg_dict[‘article_type_id‘] 21 if n1 == 0: 22 ret = ‘<a class="active" href="/app01/article-%s-0.html">全部</a>‘ % n2 23 else: 24 ret = ‘<a href="/app01/article-%s-0.html">全部</a>‘ % n2 25 return mark_safe(ret) 26 27 @register.simple_tag 28 def filter_article_type(article_type, arg_dict): 29 ‘‘‘ 30 {% for row in article_type %} 31 {% if row.id == arg_dict.article_type_id %} 32 <a class="active" href="/app01/article-{{ row.id }}-{{ arg_dict.category_id }}.html">{{ row.caption }}</a> 33 {% else %} 34 <a href="/app01/article-{{ row.id }}-{{ arg_dict.category_id }}.html">{{ row.caption }}</a> 35 {% endif %} 36 {% endfor %} 37 :return: 38 ‘‘‘ 39 ret = [] 40 for row in article_type: 41 if row.id == arg_dict[‘article_type_id‘]: 42 temp = ‘<a class="active" href="/app01/article-%s-%s.html">%s</a>‘ % 43 (row.id, arg_dict[‘category_id‘], row.caption) 44 else: 45 temp = ‘<a href="/app01/article-%s-%s.html">%s</a>‘ % (row.id, arg_dict[‘category_id‘], row.caption) 46 ret.append(temp) 47 return mark_safe(‘‘.join(ret)) 48 49 50 @register.simple_tag 51 def filter_category(category, arg_dict): 52 ‘‘‘ 53 {% for row in category %} 54 {% if row.id == arg_dict.category_id %} 55 <a class="active" href="/app01/article-{{ arg_dict.article_type_id }}-{{ row.id }}.html">{{ row.name }}</a> 56 {% else %} 57 <a href="/app01/article-{{ arg_dict.article_type_id }}-{{ row.id }}.html">{{ row.name }}</a> 58 {% endif %} 59 {% endfor %} 60 :return: 61 ‘‘‘ 62 ret = [] 63 for row in category: 64 if row.id == arg_dict[‘category_id‘]: 65 temp = ‘<a class="active" href="/app01/article-%s-%s.html">%s</a>‘ % 66 (arg_dict[‘article_type_id‘], row.id, row.name) 67 else: 68 temp = ‘<a href="/app01/article-%s-%s.html">%s</a>‘ % 69 (arg_dict[‘article_type_id‘], row.id, row.name) 70 ret.append(temp) 71 return mark_safe(‘‘.join(ret))

这样才看着高端嘛。。。给一个不会Django的看到这个模板，直接疯了，什么鬼。。。我还是回家种田吧。。。
