Flask-Admin page not found on production

Question

I have built a Flask app and deployed it to production using Vercel (formerly ZEIT). Everything works except the Flask administration.

It returns URL Not Found when accessing example.com/admin. Some have suggested to move the admin.Admin() initialization block away from the main function. But I don't know what that means. Can somebody help me?

Everything works perfect on my local machine.

Answer 1

I found the answer.

I fixed it by defining admin interface outside if name == '__main__' .

This caused the error:

if __name__ == '__main__':
     admin = Admin(application, 'AnyGeeks: Dashboard',index_view=MyIndexView())
     # Add views
     admin.add_view(UserView(Users))
     admin.add_view(ModelView(Tag))
     admin.add_view(PostView(Blog_posts))
     admin.add_view(PostView(Comments))                                                                             
     application.run(debug=True)

This what I did to fix it:

admin = Admin(application, 'AnyGeeks: Dashboard',index_view=MyIndexView())
# Add views
admin.add_view(UserView(Users))
admin.add_view(ModelView(Tag))
admin.add_view(PostView(Blog_posts))
admin.add_view(PostView(Comments))


if __name__ == '__main__':                                                                                    

   application.run(debug=True)

Now it works perfectly. I have a full website made on flask running on vercel without any issues.
