flask_whooshalchemyplus 搜索

• 搞了半天没搞好, 不过最后还是搞好了,嘿嘿嘿, 美滋滋,来首 Good Time
• 好了好了, 进入正题

1. 删库跑路, 哈哈哈 假的, 我是直接把database删了, 然后再创
2. 直接跑的话会报错, 比如像db, 还有manage.py啥的懒得写了

3. models.py

   import flask_whooshalchemyplus
   from jieba.analyse import ChineseAnalyzer
   
   class Student(db.Model):
       __tablename__ = 'student'
       __searchable__ = ['name', 'uuid']
       __analyzer__ = ChineseAnalyzer()
       id = db.Column(db.Integer, primary_key=True)
       uuid = db.Column(db.String(255), unique=True)
       name = db.Column(db.String(100))      
   
   
   flask_whooshalchemyplus.init_app(app)
   
   if __name__ == '__main__':
       db.create_all()

4. 运行models.py

5. forms.py

   from flask_wtf import FlaskForm
   from wtforms import StringField, SubmitField
   from wtforms.validators import DataRequired
   
   
   class SearchForm(FlaskForm):
       key = StringField(
           label='关键词',
           description='关键词',
           validators=[
               DataRequired('请输入关键词!')
           ],
           render_kw={
               'placeholder': '请输入关键词'
           }
       )
   
       submit = SubmitField(
           label='查询'
       )

6. views.py

   
   @app.route('/search/', methods=['POST', 'GET'])
   def search():
       form = SearchForm()
       if form.validate_on_submit():
           data = form.data
           return redirect(url_for('home.search_results', key=data['key']))
       return render_template('home/search.html', form=form)
   
   
   @home.route('/search_results/<string:key>')
   def search_results(key):
       results = Student.query.whoosh_search(key).all()
       return render_template('home/search_results.html', key=key, results=results, count=count)

7. search.html

   <form method="post">
       {{ form.key }}
       {{ form.csrf_token }}
       {{ form.submit }}
   </form>

8. search_results.html

   "{{ key }}"共有{{ count }}条
   <br>
   {% for i in results %}
       {{ i.name }}
       {{ i.uuid }}
       <br>
   {% endfor %}
