Flask

问题 I am trying to check if a value exists inside a list with dictionaries. I use flask 1.0.2. See example below: person_list_dict = [ { "name": "John Doe", "email": "johndoe@mydomain.com", "rol": "admin" }, { "name": "John Smith", "email": "johnsmith@mydomain.com", "rol": "user" } ] I found two ways to solve this problem, can you tell me which is better?: First option: jinja2 built-in template filter "map" <pre>{% if "admin" in person_list_dict|map(attribute="rol") %}YES{% else %}NOPE{% endif %}

问题 I'm more or less using the setup to run Celery tasks using your flask app context from here: http://flask.pocoo.org/docs/0.10/patterns/celery/ I'm getting the same error message as Create, manage and kill background tasks in flask app but, I'm getting it in the actual worker where the Celery task is being executed.

问题 My templates is this: {% for order in orders %} <li><h2>{{ order}}</h2> {% endfor %} and my routing function is this: @app.route('/order_history') def orderhistory(): db = get_db() cur = db.execute('select * from order_items') orders = cur.fetchall() return render_template('order_history.html', orders = orders) Any idea why I am getting row object locations instead of the db contents? 回答1: You need to get the data from the rows: {% for order in orders %} <li><h2>{{ order[0] }}</h2></li> {%

问题 I am building a small application with dash and flask. Where my user can upload his csv/excel file and have a look at the graphs being generated. I assume the size of each excel file could be around hardly 50MB max / week. I have ' ZERO ' knowledge on servers and deployment etc. Can anyone guide or enlighten me on this area. Also this application is just for an internal purpose so we are not allowed to go easy on the budget. My random google searches gave me options like, 1. AWS 2. Heroku

问题 Is there a way to access something in session set with flask.session from angular.js on the client side? I am trying to pass data and store to session in the same call from flask and be able to read it from angular later on in the flow. I am not using the templating system. For the pages, I am only serving up the index file and then using Angular to do the rest. This is my call for the index file: @app.route("/") def index(): return make_response(open('templates/index.html').read()) 回答1: If
