dash within flask app from external folder

I have seen many discussions about running dash within flask but cannot make my own case to work.
I have ~4 pages in dash and now I would like to run them with flask (using an index file works just fine).
In this thread there is some code to tackle the issue
from dash import Dash,html
from werkzeug.middleware.dispatcher import DispatcherMiddleware
import flask
from werkzeug.serving import run_simple
import dash_html_components as html
server = flask.Flask(__name__)
dash_app1 = Dash(__name__, server=server, url_base_pathname='/dashboard')
dash_app2 = Dash(__name__, server=server, url_base_pathname='/reports')
dash_app1.layout = html.Div([html.H1('Hi there, I am app1 for dashboards')])
dash_app2.layout = html.Div([html.H1('Hi there, I am app2 for reports')])
#server.route('/')
#server.route('/hello')
def hello():
return 'hello world!'
#server.route('/dashboard/')
def render_dashboard():
return flask.redirect('/dash1')
#server.route('/reports/')
def render_reports():
return flask.redirect('/dash2')
app = DispatcherMiddleware(server, {
'/dash1': dash_app1.server,
'/dash2': dash_app2.server
})
run_simple('0.0.0.0', 8080, app, use_reloader=True, use_debugger=True)
And works, however when I am trying to import my own app it doesn't due to 404 not found. I can replicate the error easily by doing having the two dash apps in separate files like this
dummy/app1.py
from dash import Dash,html
import flask
server = flask.Flask(__name__)
dash_app1 = Dash(__name__, server=server, url_base_pathname='/dashboard/')
dash_app1.layout = html.Div([html.H1('Hi there, I am app1 for dashboards')])
dummy/app2.py
from dash import Dash,html
import flask
server = flask.Flask(__name__)
dash_app2 = Dash(__name__, server=server, url_base_pathname='/reports/')
dash_app2.layout = html.Div([html.H1('Hi there, I am app2 for reports')])
wsgi.py
from werkzeug.middleware.dispatcher import DispatcherMiddleware
import flask
from werkzeug.serving import run_simple
from dummy.app1 import dash_app1
from dummy.app2 import dash_app2
server = flask.Flask(__name__)
#server.route('/')
#server.route('/hello')
def hello():
return 'hello world!'
#server.route('/dashboard/')
def render_dashboard():
return flask.redirect('/dash1/')
#server.route('/reports/')
def render_reports():
return flask.redirect('/dash2/')
app = DispatcherMiddleware(server, {
'/dash1/': dash_app1.server,
'/dash2/': dash_app2.server
})
run_simple('0.0.0.0', 8080, app, use_reloader=True, use_debugger=True)
I tried moving the server.route within each dash app but without success. what am I missing?

The react end of the application launches fine with no errors, and the database has no issues. I've used this skeleton for the base of a bunch of other projects and i've never had any issues. But for some reason i'm stuck at a brick wall setting this up. I know the issue is within the #app.route('/') part of the code. i've tried hard coding the html file into the url path, but that just causes other errors like missing 1 required positional argument: 'filename' flask. Any help is greatly appreciated

I tested your configuration and it doesn't give me any errors. Nevertheless I offer you an alternative solution.
You can provide the entire react build folder as a static folder. You can then deliver the "index.html" as a single file in the root route. The prerequisite is that the prefix for the static url path is empty.
# ...
app = Flask(__name__,
static_url_path='',
static_folder='./build'
)
# ...
#app.route('/')
def index():
return app.send_static_file('index.html')
# ...

How to configure basepath in flask restful api application?

I want to set a basepath for my flask application. I have mentioned one example below.
basepath = 'http://localhost:3000/api'
i have two api call one is GET and other one is POST .
from flask import Flask
from flask_restful import Api
app = Flask(__name__)
api = Api(app)
api.add_resource(CreateUser, "/v1/user/create/")
api.add_resource(CreateUser, "/v1/user/details")
class CreateUser(Resource):
def post(self):
# Code for creating a user
def get(self):
# Code for get the details of user.
So here, if i want to create the user then my url will be http://localhost:3000/api/v1/user/create/
so same for GET also . So how do i achieve this ?

Initialize your Api with the path prefix:
from flask import Flask
from flask_restful import Api
app = Flask(__name__)
api = Api(app, "/api")
...
You can't change the host and port this way, you'll have to run flask with parameters:
flask run --host=127.0.0.1 --port=3000
Or you could do
from flask import Flask
from flask_restful import Resource, Api
app = Flask(__name__)
api = Api(app, "/api")
...
if __name__ == "__main__":
app.run(host="127.0.0.1", port="3000")
Please keep in mind this is not intended for production environments, only for local testing. Please see https://flask.palletsprojects.com/en/1.1.x/tutorial/deploy/ for using in a production environment.
If you want to get those values from basepath, one option would be purl:
url = purl.URL('http://localhost:3000/api')
url.host() # --> "localhost"
url.port() # --> 3000
url.path() # --> "/api"

How can I run a Flask app hosted on a2hosting?

I have just setup my first Flask project hosted on a server (a2hosting). Now, I want to run on the web application my python script (calculating a few things and then redirects to other url).
But I am not sure how do I set it up on my app server in a2hosting?
# A very simple Flask Hello World app for you to get started with...
from flask import Flask ,redirect
app = Flask(__name__)
#app.route('/set/<hana>')
def hello_world(hana):
import googlemaps
name = hana
return redirect('http://mycamp.co.il/yesh/'+name , code=302)
#app.route('/hello')
def hiii():
import pymongo
def insert(myreq):
dd={
"hihi":"yes1yes"
}
myreq.insert_one(dd)
return True
client = pymongo.MongoClient("mongodb://DETAILES.#routeplan-shard-00-00-d416l.gcp.mongodb.net:27017,routeplan-shard-00-01-d416l.gcp.mongodb.net:27017,routeplan-shard-00-02-d416l.gcp.mongodb.net:27017/test?ssl=true&replicaSet=routeplan-shard-0&authSource=admin&retryWrites=true")
mydb = client['router']
myplan = mydb['planner']
mydis = mydb['distance']
myopt = mydb['optimal']
myreq = mydb['request']
myus = mydb['user']
q=insert(myreq)
return 'helo world %s' + q

Deploying Flask_restplus Api build over Flask App using uwsgi.py on nginx server

All
I have a flask_rest plus api over flask app in python. I want to deploy the same using the uwsgi format on nginx server. I searched for quite a long but didn't found the write solution.Any leads would be helpful..
Thanks in advance.
Below is the code snippet
import datetime
from fileinput import filename
import json
import os
from flask import request
from flask_restplus import Resource, Api
from werkzeug.utils import secure_filename
from APP.Application import app
from ApiConfig.ObjectConfig import Trainer, cData, Tmodal, Amodal, Cmodal
from ApiConfig.SA_utility import sentiment_sorting
from ApiConfig.appFileConfig import UPLOAD_FOLDER
from Classification.Classifier import classify
from DataBase.DB import db
from ExcelParser_DataFrame.Excel_Parser import ExcelDataFrame
from Vectorizer.Data_vector import vectorizer
from Mapper.UI_Map import UI_Map
from werkzeug.contrib.fixers import ProxyFix
api = Api(app)
app.wsgi_app = ProxyFix(app.wsgi_app)
#api.route('/sentiment-analysis/trainer')
class Upload_File(Resource):
def post(self):
..............
if __name__ == '__main__':
db.init_app(app)
db.create_all()
app.run(host='0.0.0.0')
My wsgi.py file looks like this
import sys
sys.path.insert(0, "/home/gulshan/Downloads/SA_PANDAS_SGDC/src")
from APP.Application import app
application = app
i tried using this wsgi file and started the server by firing the below command on my linux machine
uwsgi --http :5000 --wsgi-file wsgi.py --callable app --processes 4 --threads 2 --stats 127.0.0.1:9191
when i tried accessing the url using Postman then i get error as shown below:-
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<title>404 Not Found</title>
<h1>Not Found</h1>
<p>The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again.</p>
My APP.Application file looks like this:-
from flask import Flask
from ApiConfig import Settings as settings
app = Flask(__name__)
#app.config['SERVER_NAME'] = settings.FLASK_SERVER_NAME
app.config['SQLALCHEMY_DATABASE_URI'] = settings.SQLALCHEMY_DATABASE_URI
app.config['SQLALCHEMY_TRACK_MODIFICATIONS'] = settings.SQLALCHEMY_TRACK_MODIFICATIONS
app.config['SWAGGER_UI_DOC_EXPANSION'] = settings.RESTPLUS_SWAGGER_UI_DOC_EXPANSION
app.config['RESTPLUS_VALIDATE'] = settings.RESTPLUS_VALIDATE
app.config['RESTPLUS_MASK_SWAGGER'] = settings.RESTPLUS_MASK_SWAGGER
app.config['ERROR_404_HELP'] = settings.RESTPLUS_ERROR_404_HELP
app.config['SQLALCHEMY_POOL_SIZE'] = settings.SQLALCHEMY_POOL_SIZE
#app.config['SQLALCHEMY_POOL_TIMEOUT'] = settings.SQLALCHEMY_POOL_TIMEOUT
app.config['SQLALCHEMY_POOL_RECYCLE'] = settings.SQLALCHEMY_POOL_RECYCLE
app.config['SQLALCHEMY_MAX_OVERFLOW'] = settings.SQLALCHEMY_MAX_OVERFLOW

Got a solution working for me although it seems to be weird way of doing this:-
Changed my uwsgi.py
import sys
sys.path.insert(0, "/home/gulshan/Downloads/SA_PANDAS_SGDC/src")
from APP.Application import app
from flask import Flask
from SA_APP.SA import appnew
application = app
application = appnew
and added this line in my first code snippet file containing main call
api = Api(app)
appnew = app.
