改了一点上回实现的搜索功能的逻辑。每当搜索文章发现这并不是我所需要的。之前的逻辑是搜索所有的tag, title, body值，即，tag OR title OR body。
tag和title/text本身就不是一个性质，所以不能这样实现。通常搜索，都是先搜索tag，然后在下级继续搜索title或者body。也就是说tag AND (title OR body) 。
哎~ 事先没明确设计，导致出现如此问题。没办法，只能再次改逻辑了。
顺便都改为python的类。虽然我不太懂python的类到底哪里好。（#当作学习#python初学者）
services.py
- 在 services.py 创建类，之后新建account, q_titles, q_texts, q_tags, blogs 类变量。
- 创建 init 函数，定义参数 query 并赋值给类变量
- 添加 search_posts 函数。
当tag为空或者有匹配值时继续检查title或body，并且把匹配值装入另一个list里。 - 另创建 is_keywords_contains 函数，内部检查 title 和 body 值。
- 创建一个 get_tags 函数
import json
from steem import Steem
class Search:
s = Steem()
account = 'june0620'
q_titles = []
q_texts = []
q_tags = []
blogs = []
def __init__(self, query: dict):
self.q_titles = list(filter(None, query['titles']))
self.q_texts = list(filter(None, query['texts']))
self.q_tags = list(filter(None, query['tags']))
self.blogs = self.s.get_blog(self.account, 0, 400)
def search_posts(self):
s_blogs = []
for blog in self.blogs:
blog_data = blog['comment']
title = blog_data['title'].lower()
body = blog_data['body'].lower()
tags = self.get_tags(blog_data['json_metadata'])
if not self.q_tags or set(self.q_tags) & set(tags):
if not self.q_titles and not self.q_texts:
s_blogs.append(blog)
elif self.is_keywords_contains(title, body):
s_blogs.append(blog)
return s_blogs
def is_keywords_contains(self, title: str, body: str) -> bool:
if any(q_title in title for q_title in self.q_titles):
return True
if any(q_text in body for q_text in self.q_texts):
return True
return False
def get_tags(self, json_metadata: str) -> list:
'''
steempython의 get_blog()함수의 json_metadata값이 str이므로 list로 변환
'''
metadata = json.loads(json_metadata)
if metadata:
return metadata['tags']
else:
return []
views.py
继承 django的 ListView，把文章目录装入 queryset 一并映射到 html。
from django.http import HttpResponse
from django.views.generic import ListView
from .services import Search
from steem import Steem
s = Steem()
def main_view(request):
data = s.get_account('june0620')
response = HttpResponse()
response.write(data)
return response
class posts(ListView):
template_name = 'album.html'
context_object_name = 'all_posts'
def get(self, request, *args, **kwargs):
# self.queryset = s.get_blog(kwargs['account'], entry_id=0, limit=100)
query = {
'tags': ['kr'],
'titles': ['python'],
'texts': ['사랑하겠습니다']
}
se = Search(query=query)
self.queryset = se.search_posts()
return super().get(request, *args, **kwargs)
Results
经简单测试，未发现问题。
下回学习 django 的 test 功能，再好好测试一番。
