烧瓶应用搜索栏

Question

我试图使用烧瓶实现一个搜索栏，但是当我输入url/search时，我得到了一个405错误，方法不允许。

下面是我的代码片段。任何帮助都将不胜感激！

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 %}

Answer 1

因为当您手动加载页面时，您使用GET方法，但search控制器只允许使用POST。你需要改变

@app.route('/search', methods=['POST'])

至

@app.route('/search', methods=['GET', 'POST'])

更新

因此，基本上最好是改变您的search控制器。因为它没有使用search.html，而且工作错误。

@app.route('/search', methods=['GET', 'POST'])
@login_required
def search():
    form = SearchForm()
    if request.method == 'POST' and form.validate_on_submit():
        return redirect((url_for('search_results', query=form.search.data)))  # or what you want
    return render_template('search.html', form=form)

也要做缩进4个空格，就像它在佩普-8中说的

Answer 2

@app.route('/products/',methods=['GET'])
def search():    
    search = request.args.get("search")
    search="%{}%".format(search)
    products = Product.query.filter(Product.name.like(search)).all()
    return render_template("abc.html",search=search, products=products)
