py型：
1 2 3 4 5 6 7 8 9 10 11 12 13 | @staticmethod def find_users(query): search_job = str(query) sql ="""SELECT first_name,last_name, email, phone, image, diplome, latitude, longitude, description FROM users, jobs WHERE users.id_job = jobs.id AND jobs.description = %s """, [search_job] cursor = db.session.execute(sql ) # Returns a list of product tuples return cursor.fetchall() |
视图.py：
1 2 3 4 5 6 7 8 | @auth.route('/search' ) def search_user(): search_query = request.args.get('query') users = User.find_users(search_query) return render_template("home/search_results.html", query=search_query, users=users) |

主页.html：
1 2 3 4 5 6 7 | <form class="navbar-form navbar-left" action="{{url_for('auth.search_user') }}"> <input type="text" class="form-control" name="query" placeholder="Search"> <input type="hidden" name="index" value="All"> <button type="submit" class="btn btn-default">Search</button> </form> |
这是我用来执行这个请求的所有代码，你知道吗？谢谢您。
注意：当我在我的模型中给出一个值时，它是有效的。
jobs.description = %s -with-> jobs.description ="value"

thas是我在models.py中的解决方案，它起作用：)
1 2 3 4 5 6 7 8 9 | @staticmethod def find_handymans(query): search_job = str(query) sql_query =text("SELECT first_name,last_name, email, user_type, phone, image, diplome, latitude, longitude, description FROM users, jobs WHERE users.id_job = jobs.id AND jobs.description = :x") cursor = db.session.execute(sql_query,{'x' : search_job}) # Returns a list of product tuples return cursor.fetchall() |
