I'm creating my forms without the scaffold script, and now, I
needed to add one more column in my table. But how can I update this?
When I type something in this new text field, my database do not
insert this new data.
I’m not totally clear what you mean. Once, you add a field to your
table, you will also need to add a text field for it in your form_tag
or form_for in your view. Can you post the code you’re using in your
view with the form and also the code that performs the action.
