Pass variables between different scripts python

Question

I made a script python app.py and I managed to store data from a javascript form, thanks to a flask app :

app = Flask(__name__)
app.config.from_object('config')
db.init_app(app)

@app.route('/getFormData', methods=['POST'])
def get_javascript_data():
    params = request.form.to_dict()
    sunElevation = params['sunElevation']
    cloudCoverage = params['cloudCoverage']
    thresholdNDVI = params['thresholdNDVI']
    limitScene = params['limitScene']
    city = params['city']
    data_search = passData(sunElevation, cloudCoverage, thresholdNDVI, limitScene, city)
    return jsonify(data_search.data_dict)

if __name__ == '__main__':
    app.run()

Here is the definition of the class passData, in models.py :

class passData:
    def __init__(self, sunElevation, cloudCoverage, thresholdNDVI, limitScene, city):
        self.sunElevation = sunElevation
        self.cloudCoverage = cloudCoverage
        self.thresholdNDVI = thresholdNDVI
        self.limitScene = limitScene
        self.city = city
        self.data_dict = [{'sunElevation':self.sunElevation,'cloudCoverage':self.cloudCoverage, 'thresholdNDVI':self.thresholdNDVI, 'limit':self.limitScene, 'city':self.city}]

I need to use those different parameters (sunElevation...) in an other script, in a other folder, to execute a search of imagery and then run the script associated. My problem is that I don't know how to pass those data, because they seem to only exist in the fonction defined in the get_javascript_data().

If someone has an idea that could help me !

Answer 1

You just have to import the other script, call the function and pass the parameters:

app = Flask(__name__)
app.config.from_object('config')
db.init_app(app)

from path.to.your.file import your_function


@app.route('/getFormData', methods=['POST'])
def get_javascript_data():
    params = request.form.to_dict()
    sunElevation = params['sunElevation']
    cloudCoverage = params['cloudCoverage']
    thresholdNDVI = params['thresholdNDVI']
    limitScene = params['limitScene']
    city = params['city']
    data_search = passData(sunElevation, cloudCoverage, thresholdNDVI, limitScene, city)

    # call the function and pass the parameters
    your_function(sunElevation, cloudCoverage) #...

    return jsonify(data_search.data_dict)

Try adding the following code in your file, then import the script

import os, sys
sys.path.append(os.path.abspath(os.path.join(os.path.dirname(__file__), '..', '..')))
