【Python之路】特别篇--组合搜索功能实现
组合搜索：
根据特定标签内容，返回符合的数据。
效果图:
设计规划：
一、数据库表划分：
1.方向表，（运维自动化，Python开发，。。）
2.分类表，（Python，Java，C#，。）
3.多对多,方向与分类外键表，
4.视频表，（视频1，视频2，。。。）
二、表间关系：
方向表与分类表：为多对多关系，
1个方向可以有多种分类，1个分类可以同时对应多个方向。
分类表与视频表：一对多关系，
1个分类可以有多个视频。
三、表内详细设计：
方向表：
class Direction(models.Model): weight = models.IntegerField(verbose_name='权重（按从大到小排列）', default=0) name = models.CharField(verbose_name='名称', max_length=32) classification = models.ManyToManyField('Classification') class Meta: db_table = 'Direction' verbose_name_plural = u'方向（视频方向）' def __str__(self): return self.name
classfication为方向表（Direction）多对多关系字段；
分类表：
class Classification(models.Model): weight = models.IntegerField(verbose_name='权重（按从大到小排列）', default=0) name = models.CharField(verbose_name='名称', max_length=32) class Meta: db_table = 'Classification' verbose_name_plural = u'分类（视频分类）' def __str__(self): return self.name
视频表：
class Video(models.Model): status_choice = ( (0, u'下线'), (1, u'上线'), ) level_choice = ( (1, u'初级'), (2, u'中级'), (3, u'高级'), ) status = models.IntegerField(verbose_name='状态', choices=status_choice, default=1) level = models.IntegerField(verbose_name='级别', choices=level_choice, default=1) classification = models.ForeignKey('Classification', null=True, blank=True) weight = models.IntegerField(verbose_name='权重（按从大到小排列）', default=0) title = models.CharField(verbose_name='标题', max_length=32) summary = models.CharField(verbose_name='简介', max_length=32) img = models.ImageField(verbose_name='图片', upload_to='./static/images/Video/') href = models.CharField(verbose_name='视频地址', max_length=256) create_date = models.DateTimeField(auto_now_add=True) class Meta: db_table = 'Video' verbose_name_plural = u'视频' def __str__(self): return self.title
level为等级字段,status为视频状态字段；
具体效果：
通过对比其他同类型的搜索示例发现，他们大多数都通过URL地址来向后台传递类别 id 查询数据库，然后返回数据给前端页面。
可以发现：方向对应第一个数字，分类对应第二个数字，等级对应第三个数字。
方向的标签代码为：
当点击分类或等级时，其自身对应的id数字会发生改变，而另外两个数字id不产生变化。
设计步骤：
1.我们先设计出通过输入网页URL地址的方式，动态改变页面标签代码中的值。
设计URL选择器，正则表达式:
url(r'^video-(?P<direction_id>\d+)-(?P<classfication_id>\d+)-(?P<level_id>\d+).html', views.video),
direction_id 为获得方向id，classfication_id为获得分类id，level_id为获得等级id
2.输入url： /video-1-2-1.html 后参数传递给 views.video()函数处理。
def video(request,*args,**kwargs): current_url = request.path #当前输入网页路径 /video-0-0-0.html direction_id = int(kwargs.get('direction_id')) #获得相应的id classfication_id = int(kwargs.get('classfication_id')) level_id = int(kwargs.get('level_id'))
接下来通过获得的id数据查询数据库信息；
此时，我们得知数据库中id字段是从1开始递增，所以我们设计当id=0 时为获得全部数据。
1.当方向为0时，表示直接从数据库获取所有的分类信息：
由于，方向字段在网页上表现为永远显示全部数据。所以设计如下
def video(request,*args,**kwargs): # ...... 省略了部分 # 获得所有方向信息: direction_list = models.Direction.objects.all().values('name','id') if direction_id != 0 : # 分类不等于0 即选择了其中一个分类, /video-1-3-1.html # 取 url相对应的分类信息(根据 方向id 进行查询,连表查询) direction = models.Direction.objects.get(id=direction_id) classfication_list = direction.classification.values('name', 'id') else: classfication_list = models.Classification.objects.all().values('name','id') #分类等于0 为 全部, 直接取全部分类数据 # 获得所有等级信息 # level_list = models.Video.level_choice ret = map(lambda x:{'name':x[1],'id':x[0]},models.Video.level_choice) level_list = list(ret) # 数据返回前端页面 return render(request,'video.html',{'direction_list':direction_list,'class_list':classfication_list,'level_list':level_list,'current_url':current_url})
其中，等级信息，存放在video表中的level字段中，以元组形式存放，为了统一我们将（元组,..）的形式 => [字典,..]，使用了map()函数
向前端页面返回了，方向，分类，等级的数据和当前url地址。 /video-1-3-1.html。
核心：前端接收到当前url地址后，通过模版语言simple_tag，动态的构造a标签的href属性，即可表现为当改变url时，标签href也同时发生改变
前端页面：
<div> {% for item in direction_list %} {% simple_tag函数 current_url item %} {% endfor %} </div>
3.设计simple_tag函数。
需要在项目app下创建 templatetags包， 然后自定义一个文件 xx.py
from django import template from django.utils.safestring import mark_safe register = template.Library() @register.simple_tag def action1(current_url, item): url_part_list = current_url.split('-') # 如果当前url中第一个位置 video-2-0-0.html if str(item['id']) == url_part_list[1]: temp = "<a href='%s' class='active'>%s</a>" else: temp = "<a href='%s'>%s</a>" url_part_list[1] = str(item['id']) ur_str = '-'.join(url_part_list) temp = temp %(ur_str, item['name']) return mark_safe(temp)
得到了一个处理 方向 标签的模板函数，方向、等级标签的处理方式同上，只是url切割的位置稍有不同！
{% load newtag %} <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> <style> a{ display: inline-block; padding: 8px; } .active{ background-color: coral; color: white; } </style> </head> <body> <h3>选择：</h3> <div> {% for item in direction_list %} {% action1 current_url item %} {% endfor %} </div> <div> {% for item in class_list %} {% action2 current_url item %} {% endfor %} </div> <div> {% for item in level_list %} {% action3 current_url item %} {% endfor %} </div> <hr /> <div> </div> <h3>视频：</h3> <hr /> </body> </html>
from django import template from django.utils.safestring import mark_safe register = template.Library() @register.simple_tag def action1(current_url, item): # videos-0-0-1.html # item: id name # video- 2 -0-0.html url_part_list = current_url.split('-') # 如果当前url中第一个位置 video-2-0-0.html if str(item['id']) == url_part_list[1]: temp = "<a href='%s' class='active'>%s</a>" else: temp = "<a href='%s'>%s</a>" url_part_list[1] = str(item['id']) ur_str = '-'.join(url_part_list) temp = temp %(ur_str, item['name']) return mark_safe(temp) @register.simple_tag def action2(current_url, item): # videos-0-0-1.html # item: id name url_part_list = current_url.split('-') # 如果当前url中第一个位置 video-2-0-0.html if str(item['id']) == url_part_list[2]: temp = "<a href='%s' class='active'>%s</a>" else: temp = "<a href='%s'>%s</a>" url_part_list[2] = str(item['id']) ur_str = '-'.join(url_part_list) temp = temp %(ur_str, item['name']) return mark_safe(temp) @register.simple_tag def action3(current_url, item): # videos-0-0-1.html # item: id name url_part_list = current_url.split('-') # 如果当前url中第三个位置 video-2-0-0.html if str(item['id']) == url_part_list[3].split('.')[0]: temp = "<a href='%s' class='active'>%s</a>" else: temp = "<a href='%s'>%s</a>" url_part_list[3] = str(item['id']) + '.html' ur_str = '-'.join(url_part_list) temp = temp %(ur_str, item['name']) return mark_safe(temp)
然后再设计一个在前端同时输出, "全部" 的simple_tag函数
{% load newtag %} <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> <style> a{ display: inline-block; padding: 8px; } .active{ background-color: coral; color: white; } </style> </head> <body> <h3>选择：</h3> <div> {% action_all current_url 1 %} : {% for item in direction_list %} {% action1 current_url item %} {% endfor %} </div> <div> {% action_all current_url 2 %} : {% for item in class_list %} {% action2 current_url item %} {% endfor %} </div> <div> {% action_all current_url 3 %} : {% for item in level_list %} {% action3 current_url item %} {% endfor %} </div> <hr /> <div> </div> <h3>视频：</h3> <hr /> </body> </html>
@register.simple_tag def action_all_1(current_url): """ 获取当前url，video-1-1-2.html :param current_url: :param item: :return: """ url_part_list = current_url.split('-') if url_part_list[1] == "0": temp = "<a href='%s' class='active'>全部</a>" else: temp = "<a href='%s'>全部</a>" url_part_list[1] = "0" # video 0 1 2.html href = '-'.join(url_part_list) temp = temp % (href,) return mark_safe(temp) @register.simple_tag def action_all_2(current_url): """ 获取当前url，video-1-1-2.html :param current_url: :param item: :return: """ url_part_list = current_url.split('-') if url_part_list[2] == "0": temp = "<a href='%s' class='active'>全部</a>" else: temp = "<a href='%s'>全部</a>" url_part_list[2] = "0" # video 0 1 2.html href = '-'.join(url_part_list) temp = temp % (href,) return mark_safe(temp) @register.simple_tag def action_all_3(current_url): """ 获取当前url，video-1-1-2.html :param current_url: :param item: :return: """ url_part_list = current_url.split('-') # video 0 1 2.html if url_part_list[3] == "0.html": temp = "<a href='%s' class='active'>全部</a>" else: temp = "<a href='%s'>全部</a>" url_part_list[3] = "0.html" href = '-'.join(url_part_list) temp = temp % (href,) return mark_safe(temp)
为了降低simple_tag代码过于冗余,我们用if..else统一归类成一个函数:
{% load newtag %} <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> <style> a{ display: inline-block; padding: 8px; color: black; text-decoration: none; } .alt{ color: black; font-weight: bolder; } .active{ background-color: coral; color: white; } .item-list{ margin: 6px; } .video-list{ display: inline-block; margin: 6px; } .video-list img{ height: 160px; width: 250px; border:0 ; overflow: hidden; } </style> </head> <body> <h3>选择:</h3> <div class="item-list"> <a href="javascript:;" class="alt">方向 :</a> {% action_all current_url 1 %} {% for item in direction_list %} {% action current_url item 1 %} {% endfor %} </div> <div class="item-list"> <a href="javascript:;" class="alt">分类 :</a> {% action_all current_url 2 %} {% for item in class_list %} {% action current_url item 2 %} {% endfor %} </div> <div class="item-list"> <a href="javascript:;" class="alt">等级 :</a> {% action_all current_url 3 %} {% for item in level_list %} {% action current_url item 3 %} {% endfor %} </div> <hr> <h3>视频:</h3> <hr> </body> </html>
from django import template from django.utils.safestring import mark_safe register = template.Library() @register.simple_tag def action_all(current_url,index): url_split = current_url.split('-') if index == 3: if url_split[index] == '0.html': TEMP = ''' <a href='%s' class='active'>全部</a> ''' else: TEMP = ''' <a href='%s'>全部</a> ''' url_split[index] = '0.html' else: if url_split[index] == '0': TEMP = ''' <a href='%s' class='active'>全部</a> ''' else: TEMP = ''' <a href='%s'>全部</a> ''' url_split[index] = '0' url_str = '-'.join(url_split) TEMP = TEMP % (url_str) return mark_safe(TEMP) @register.simple_tag def action(current_url,item,index): url_split = current_url.split('-') if index == 3: if url_split[index].split('.')[0] == str(item['id']): TEMP = ''' <a href='%s' class='active'>%s</a> ''' else: TEMP = ''' <a href='%s'>%s</a> ''' url_split[index] = str(item['id']) + '.html' else: if url_split[index] == str(item['id']): TEMP = ''' <a href='%s' class='active'>%s</a> ''' else: TEMP = ''' <a href='%s'>%s</a> ''' url_split[index] = str(item['id']) url_str = '-'.join(url_split) TEMP = TEMP%(url_str,item['name']) return mark_safe(TEMP)
至此,我们已经完成了 页面上输出全部的方向、分类、等级的数据，以及通过url地址改变动态修改了a标签href代码和添加了选中时特效。我们还需要添加限制规则，规定当 方向 改变时，出现不同的分类！
4.进一步考虑添加规则!
当输入的url中,方向id等于0 时, => 显示全部分类， video-0-0-2.html
不等于0 时,=> if 分类id等于0 => 分类根据 方向id 取出数据
不等于0 => 分类根据 方向id 取出数据 当先输入的url中，分类id没有出现在通过查询获得的分类id时，需要把分类id 置为0。
def video(request,*args,**kwargs): current_url = request.path direction_id = int(kwargs.get('direction_id')) classfication_id = int(kwargs.get('classfication_id')) level_id = int(kwargs.get('level_id')) direction_list = models.Direction.objects.all().values('name','id') if direction_id == 0 : # 方向 = 0 # 分类全部显示 classfication_list = models.Classification.objects.all().values('name', 'id') else: # 方向 != 0 , 分类 根据方向,查询 if classfication_id == 0: # 分类为0 ,根据url方向 取全部 direction = models.Direction.objects.get(id=direction_id) classfication_list = direction.classification.values('name', 'id') classfication_id_list = list(map(lambda x: x['id'], classfication_list)) else: # 分类不为0 , 根据具体方向,取具体分类 direction = models.Direction.objects.get(id=direction_id) classfication_list = direction.classification.values('name', 'id') classfication_id_list = list(map(lambda x: x['id'], classfication_list)) if classfication_id in classfication_id_list: pass else: url_list = current_url.split('-') url_list[2] = '0' current_url = '-'.join(url_list) # 等级,统一格式,规范化输出 # level_list = models.Video.level_choice ret = map(lambda x:{'name':x[1],'id':x[0]},models.Video.level_choice) level_list = list(ret) return render(request,'video.html',{'direction_list':direction_list, 'class_list':classfication_list, 'level_list':level_list, 'current_url':current_url, })
5.最后考虑输出视频数据:
当方向、分类、等级id都为0时,输出全部的视频;
当方向=0、分类！=0时，根据分类id查询数据库
当方向！=0、分类=0时，根据分类id查询数据库
当方向！=0、分类!=0时，根据分类id查询数据库
当等级!=0时, 根据分类id,等级id查询数据库
def video(request,*args,**kwargs): current_url = request.path direction_id = int(kwargs.get('direction_id')) classfication_id = int(kwargs.get('classfication_id')) level_id = int(kwargs.get('level_id')) q={} q['status'] = 1 direction_list = models.Direction.objects.all().values('name','id') if direction_id == 0 : # 方向 = 0 # 分类全部显示 classfication_list = models.Classification.objects.all().values('name', 'id') if classfication_id == 0: # 方向全部,分类全部,视频显示全部 pass else: # 方向全部,分类部分,视频属于分类下的 q['classification__in'] = [classfication_id,] else: # 方向 != 0 , 分类 根据方向,查询 if classfication_id == 0: # 分类为0 ,根据url方向 取全部 direction = models.Direction.objects.get(id=direction_id) classfication_list = direction.classification.values('name', 'id') classfication_id_list = list(map(lambda x: x['id'], classfication_list)) q['classification__in'] = classfication_id_list else: # 分类不为0 , 根据具体方向,取具体分类下视频 direction = models.Direction.objects.get(id=direction_id) classfication_list = direction.classification.values('name', 'id') classfication_id_list = list(map(lambda x: x['id'], classfication_list)) # 方向部分,分类部分,视频属于分类下的 q['classification__in'] = [classfication_id,] if classfication_id in classfication_id_list: pass else: url_list = current_url.split('-') url_list[2] = '0' current_url = '-'.join(url_list) # 等级,统一格式,规范化输出 # level_list = models.Video.level_choice ret = map(lambda x:{'name':x[1],'id':x[0]},models.Video.level_choice) level_list = list(ret) # 如果选择了等级 , 获取id , 否则显示全部 if level_id != 0: q['level'] = level_id video_list = models.Video.objects.filter(**q).values('title','summary','img','href') return render(request,'video.html',{'direction_list':direction_list, 'class_list':classfication_list, 'level_list':level_list, 'current_url':current_url, 'video_list':video_list, })
注意: 查询时,可以通过构造一个字典的方式添加查询条件,返回最终结果。
q = {} ret = models.X.objects.filter(**q).values('..,..')
