In the current version of DataTables (1.10.4) you can simply add destroy:true to the configuration to make sure any table already present is removed before being re-initialised. $(‘#example’).dataTable({ destroy: true, aaData: response.data });
I rewrote your code in a more organized, better-practiced way: import tkinter as tk class Demo1: def __init__(self, master): self.master = master self.frame = tk.Frame(self.master) self.button1 = tk.Button(self.frame, text=”New Window”, width = 25, command = self.new_window) self.button1.pack() self.frame.pack() def new_window(self): self.newWindow = tk.Toplevel(self.master) self.app = Demo2(self.newWindow) class Demo2: def __init__(self, master): self.master = master self.frame … Read more
You can not do exactly what you want to do right now, anyway, the best approach right now is to check when the application it’s running in background/inactive using the AppLifecycleState from the SDK (basically does what your library is trying to do) The library that you are using it’s outdated, since a pull request … Read more
Prior to C++20, objects’ destructors were always called prior to calling their operator delete. With destroying operator delete in C++20, operator delete can instead call the destructor itself. Here’s a very simple toy example of non-destroying vs. destroying operator delete: #include <iostream> #include <new> struct Foo { ~Foo() { std::cout << “In Foo::~Foo()\n”; } void … Read more
It really depends on what you want to do in your onDestroy. This is what super.onDestroy does (in that order): Dismiss any dialogs the activity was managing. Close any cursors the activity was managing. Close any open search dialog If the logic you put inside onDestroy has something to do with those three things that … Read more
You shouldn’t use a postgres command to fully delete your database, as you will not have permissions to create a new one. Instead you should use the heroku command to clear out your database: heroku pg:reset DATABASE_URL
Create a new column in the ci_session table. ALTER TABLE `yourdatabase`.`ci_sessions` ADD COLUMN `userid` VARCHAR(45) NULL AFTER `user_data` ; Then in your login function get the id from your login process and before adding the userdata information to the session do: /* Delete any existing sessions with the current userid session.

class Model def self.dedupe # find all models and group them on keys which should be common grouped = all.group_by{|model| [model.name,model.year,model.trim,model.make_id] } grouped.values.each do |duplicates| # the first one we want to keep right? first_one = duplicates.shift # or pop for last one # if there are any more left, they are duplicates # so … Read more
You could put all of your code under one namespace like this: var namespace = {}; namespace.someClassObj = {}; delete namespace.someClassObj; Using the delete keyword will delete the reference to the property, but on the low level the JavaScript garbage collector (GC) will get more information about which objects to be reclaimed. You could also … Read more
You’re looking for unset(). But take into account that you can’t explicitly destroy an object. It will stay there, however if you unset the object and your script pushes PHP to the memory limits the objects not needed will be garbage collected. I would go with unset() (as opposed to setting it to null) as … Read more
