Hide and show model field

How to hide and show model field based on the value of the other field of model in django?

It depends.

Are you talking about a display of a model, or a form based on a model?

Are you building your views yourself, or are you using one of the generic class based views?

If it’s a form, are you looking to do this dynamically on the browser-side? (In which case the solution will involve some javascript.)

All of these factors will affect the selection of the appropriate solution.

It would be most helpful if you would post a minimum sample of the code you’re working from (models, forms, views, template) along with a more detailed explanation of what you’re trying to accomplish.
