Thank you for your response.
There is no direct releationship between customers and course tables.
Then in order to have such a relationship (or the inverse – a lack of
relationship) between any given Course and any given Customer, you will
need to store that graph somewhere. I would make a new Enrollment model,
and give it the following attributes:
You could add other decorations to it if you like, certainly the default
timestamps could be useful, but you could also add a column for how much
the customer paid, any other details about this transaction you need to
store and retrieve later.
Then, in the model file, you would add
And in your Course and Customer models, you would add the same
declaration in each:
And the specific declaration for each:
has_many :courses, :through => :enrollment
has_many :customers, :through => :enrollment
Could you please be more specific in regard to:
One way might be to have a form_for @course on your Customers#index
page, and a submission of that to the CoursesController would build a
new Enrollment for each submitted Customer on that Course.
I just want to display all customers for a selection (checkbox style).
The rest is pretty easy. If you have a form for a course, you can gather
all of the possible attendees for that course using
@customers = Customer.all
in your CoursesController. The relationship will take care of everything
In your enrollment form view, you would then iterate over those, and
build your checkboxes (I’ve left out all the html and erb tags for
form_for @course do |f|
@customers.each do |customer|
f.check_box [:customers, customer],
f.label customer.name, [:customers, customer]
That’s off the top of my head, but it should point you in a working
