我想用Flask实现搜索栏,但是当我输入url/search时,出现了405错误,方法不允许。Flask应用搜索栏
这是我的代码片段。任何帮助,将不胜感激!
forms.py
from wtforms import StringField
from wtforms.validators import DataRequired
class SearchForm(Form):
search = StringField('search', [DataRequired()])
submit = SubmitField('Search',
render_kw={'class': 'btn btn-success btn-block'})
views.py
from flask_login import login_required
from forms import SearchForm
from models import User
@app.route('/')
def index():
if current_user.is_authenticated:
return redirect(url_for('profile'))
return render_template('index.html')
@app.route('/profile', methods=['GET', 'POST'])
@login_required
def profile():
# some code to display user profile page
@app.route('/search', methods=['POST'])
@login_required
def search():
form = SearchForm()
if not form.validate_on_submit():
return redirect(url_for('index'))
return redirect((url_for('search_results', query=form.search.data)))
@app.route('/search_results/<query>')
@login_required
def search_results(query):
results = User.query.whoosh_search(query).all()
return render_template('search_results.html', query=query, results=results)
models.py
from flask_sqlalchemy import SQLAlchemy
from flask_whooshalchemy import whoosh_index
from app import app
db = SQLAlchemy()
class User(db.model):
__searchable__ = ['name']
id = db.Column(db.Integer, primary_key=True)
name = db.Column(db.String(64))
whoosh_index(app, User)
search.html
{% extends 'layouts/base.html' %}
{% set page_title = 'Search' %}
{% block body %}
<div>
{{ render_form(url_for('search'), form) }} # note: render_form is some marco from another .html file
</div>
{% endblock %}
感谢说,但是当我加''GET'',我现在得到302错误。在views.py中看到index()可能会有所帮助,因此我只是添加了它 – PSNR
302不是错误。这是您在“搜索”中发送的重定向。 – dirn
是的,但我得到** ERR_TOO_MANY_REDIRECTS **和搜索栏不会显示在搜索页面 – PSNR
