python - How to add a blueprint and a url rule to an extension and not in the flask project -


i trying learn making flask extensions. want after my_extention.init_app(app) in application factory add view in flask-admin. example my_extension.add_view(name='view extension'). create endpoint localhost:5000/myextension/test. again want extension this.

from flask import blueprint, jsonify flask.views import methodview  class flaskmyextension(object):     def __init__(self, app=none):         if app:             self.init_app(app)         self.module = none      def init_app(self, app):         print('[-] extension: registering blueprints')         self.register_blueprint(app)      def register_blueprint(self, app):         self.myextension = blueprint(             "myextension", __name__, template_folder="templates"         )         app.register_blueprint(self.module)         return self.myextension      # def add_view(self):     #     try:     #         self.blueprint.add_url_rule("/test", view_func=test.as_view('test'), methods=['get', 'post', 'put', 'delete'])     #     except exception e:     #         print(e)

the view be

class test(methodview):      def get(self):         return jsonify({"status":"ok"})      def post(self):         return jsonify({"status":"ok"})      def put(self):         return jsonify({"status":"ok"})      def delete(self):         return jsonify({"status":"ok"})

i have templates folder. simple jsonify('you extensions test view') more enough.

thank you

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
