Is there a way to take user input from HTML, and use python to run the input through to a SQL database? Does the input need to be parsed? I want the the user to be able to type in a store name, and for it to return relevant rows
def search():store_search = request.form.get("store")if request.method == "POST":if not store_search:return "please type in a store!"else:c = conn.cursor()c.execute("SELECT * FROM stores WHERE store_name= 'store_search'")rows = c.fetchall()for eachRow in rows:return rowelse:
return render_template("search.html")
HTML:
{% extends "main_page.html" %}
{% block title %}
Search
{% endblock %}{% block main %}<form action="{{ url_for('search') }}" method="post"><fieldset><div class="form-group"><input autocomplete="off" autofocus class="form-control" name="store" placeholder="store" type="text"/></div><div class="form-group"><button class="btn btn-default" type="submit">search</button></div><div class="page-header"><h1>{{ store }}</h1></div></fieldset></form>
{% endblock %}
You can create a simple app in flask that receives user input and scans the items returned from a SELECT query in sqlite3:
First, create the user form. You can use ajax with jquery for a dynamic response:
In search.html:
<html><head><script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script></head><body> <input type='text' name='query' id='query'><button type='button' id='search'>Search</button><div id='results'></div></body><script> $(document).ready(function() {$('#search').click(function() {var text = $('#query').val();$.ajax({url: "/search",type: "get",data: {query: text},success: function(response) {$("#results").html(response.html);},error: function(xhr) {//Do Something to handle error}});});});</script>
</html>
In app.py
import flask
import sqlite3
app = flask.Flask(__name__)@app.route('/')
def home():return "<a href='/search'>Search</a>"@app.route('/search')
def search():term = flask.request.args.get('query')possibilities = [i for [i] in sqlite3.connect('filename.db').cursor().execute("SELECT * FROM stores") if term.lower() in i.lower()]return flask.jsonify({'html':'<p>No results found</p>' if not possibilities else '<ul>\n{}</ul>'.format('\n'.join('<li>{}</li>'.format(i) for i in possibilities))})
