Form fields

Rails
1

Hi,

Background:
I have customer’s details in the customers table (for example email,
address…)

Whenthat customer proceeds to checkout (which is controlled by the
cart_controller not the customer-controller), the checkout form fields
display empty. For example:

Address

<%= text_field :order, :ship_to_address %>

How can I show the customer’s details in the form fields? but still
use the form input to process the order?

TIA,
Elle

Take a look at form_for.

The relationships are already in place. I’m just not sure how the
checkout form can display custotmer’s details (if they exist), so the
customer doesn’t have to re-type them all the time.

I think what you’re looking for is text_field_tag:

text_field is tied to a model attribute and uses only its actual value.
text_field_tag lets you set up your own field and load your own value.
For example:

<%= text_field_tag ‘order[ship_to_address]’,
@order.ship_to_address || @customer.address %>

This will preload the field with the given value from @customer. The ||
expression is for loading it from an existing order instance if the
customer has already filled this out.

I’m not sure what you mean. I had a look at form_for and it looks the
same, besides the way to lay out your fields. It still sends me to the
same action.

I’m probably missing something. Can form_for do that?
