Question

I’m trying to pass some parameters (count) from a form to a model.

The model basically creates a user X times.

In our form, we have this:

= f.text_field :count

And I can see this is submitted properly in the dev. log:

user"=>{"count"=>"2"}

I’ve tried this in my controller:

@user = User.generate(params[:count])

Generate is then supposed to call this in my user model:

def self.generate(count=10)
  count.times do
  .....
end

I basically need the ’10’ replaced with the count from form.

How can I go about this?

— UPDATE 1 —

I’ve edited as below but get had to change from count to usercount because I think that’s reserved in rails..

I have this in my controller:

@user = User.generate(params[:user][:usercount])

This in my user.rb:

attr_accessor :usercount   

def self.generate
  usercount.times do
  ...
end

When I submit, I get this:

ArgumentError (wrong number of arguments (1 for 0)):
  app/models/user.rb:22:in `generate'
  app/controllers/users_controller.rb:38:in `new_users_create'

Really frustrating…

Answer 1

class User
  attr_accessor :count
end

@user = User.generate(params[:user][:count])

should work fine.
