在函数参数中包含字典的同时将数据发送到python烧瓶中的html仪表板 [英] send data to html dashboard in python flask while having dictionary in a function parameter

问题描述

我想在flask框架中将数据发送到html，我有一个接收字典作为参数的函数，然后在字典上应用了几个函数.在最终结果之后，我想渲染到html页面.我已经从不同的博客尝试了48小时，但没有得到精确的解决方案.

I want to send data to html in flask framework, i have a function which receives dictionary as a parameter, then there are several functions applied on dictionary. after that final result i want to render in to html page. Its been 48 hours i am trying from different blogs but didn't get precise solution.

imports ...
from other file import other_functions
from other file import other_functions_2
from other file import other_functions_3

app = Flask(__name__, template_folder='templates/')

@app.route("/dashboard")
def calculate_full_eva_web(input:dict):

   calculate_gap = other_functions(input)
   calculate_matrix = other_functions_2(input)
   average = other_functions_3(input)
   data = dict{'calculate_gap':calculate_gap, 'calculate_matrix':calculate_matrix,'average':average}

   return render_template('pages/dashboard.html', data = data) 

if __name__ == "__main__":
    app.run(debug=True)

推荐答案

Flask可以路由到的方法不要将字典作为输入，并且它们接受的参数必须通过路由中的模式进行匹配.(请参见 https://flask.palletsprojects.com/en/1.1.x/api/#url-route-registrations )

Methods that Flask can route to don't take dictionaries as inputs, and the arguments they do take need to be matches by a pattern in the route. (See https://flask.palletsprojects.com/en/1.1.x/api/#url-route-registrations)

如果您进行更改，将会收到相同的错误

You'd get the same error if you changed

@app.route("/dashboard")
def calculate_full_eva_web(input:dict):

到

@app.route("/dashboard")
def calculate_full_eva_web(input):

您的前进路径取决于发出请求时如何传递数据.您可以通过URL参数传递键/值对，并通过 request.args 对象检索它们.那可能已经足够接近您想要的了.(您需要从 calculate_full_eva_web()中删除参数声明)

Your path forward depends on how you want to pass data when you make the request. You can pass key/value pairs via URL parameters and retrieve them via the request.args object. That might be close enough to what you want. (You'll need to remove the argument declaration from calculate_full_eva_web())

类似

from flask import request

@app.route('/dashboard')
def calculate_full_eva_web():
    input = request.args
