Question

ive generated a scaffolding for my application. The DB has a date and time field that I want to set tu current date and time that the form is submitted.

I created at _form.html.erb

<div class="field">
    <%= f.label :t_date %><br />
    <%= f.date_select :t_date %>
  </div>

   <div class="field">
    <%= f.label :t_time %><br />
    <%= f.time_select :t_time %>
  </div>

But I dont want the user to set them, but the have to pass as a form argument.
I tought about hidden fields for them, but even if I set them as hidden, you could send a bad form trought json or a POST request am i right?
What would be the right way to pass the current date and time, save them to the db and showing them without the user notice?

Answer 1

If the form is used to create or update a model, you would just use the timestamping facility that Activerecord provides.

From the docs:

Active Record automatically timestamps create and update operations if
the table has fields named created_at/created_on or
updated_at/updated_on.
