Re: how i can unlock all the career items

@simvips If I understand correctly what you want, you don't need to cheat.

Go to Manage World view, the map picture. Then enter a lot through Build mode, the little icon with a hammer. It can be any kind of venue, just not a residential with sims living on it.
When you now go into buy mode you can access the items that belong to careers and previous challenges (the unlocked objects), including the green flower pot in your picture.
If you want your particular sims to use them, you can build a house and place the unlocked objects in it, then move your household there later.

If I need to explain differently please ask again.
