python - Flask error handler -

i created simple multi-application flask site. moved errors view (404, 501, etc.) application errors. when error occures see default error pages of flask, not own. structure of project is:

/site |-> main.py      flask import flask       app = flask(__name__)      app.config.from_pyfile('config.py')       import errors, account, mysite, blog      errors.views import not_found       @app.route("/")      def index_view():          return "welcome!"       @app.route("/about")      def about_view():          return "about"       if __name__ == "__main__":          app.run(debug=true) |-> templates   |-> errors     |-> 404.html  |->errors   |-> __init__.py      main import app      import errors.views   |-> views      errors import app      flask import render_template       @app.errorhandler(404)      def not_found(error):          return render_template('errors/404.html'), 404 

if returning content of errors/views.py main.py begins work expected , show me error page.

put error templates 404 etc. in main templates folder of project. if project called "myproject", can have like:

myproject/     __init__.py     templates         404.html         503.html         .. , on 

call these in __init__.py file as:

app = flask(__name__)  @app.errorhandler(404) def not_found(error):     return render_template('404.html'), 404
