Question

How do I create a column in my table that is an input field?

i cant find it anywhere,

I’m looking to have the column for a price that is set at nil/empty, whatever.

Then the user inputs a price which is validated against a reserver price column, if successful it is added to cart.

It’s the first part I’m having bad trouble with as my cart is set up already

You’ll need a migration that adds a string field do your database. Check out the Rails guide for information on migrations, but it’s essentially this:

add_column :my_table, :my_field, :string

Then it will automatically be cast to a string when retrieved from the database. Once you have that field, you can use the form helpers:

<%= form_for @my_model do |f| %>
  <%= f.text_field :my_field %>
  <%= f.submit %>
<% end %>
