I’m in the process of creating a sign up form for an online application.  
The form collects account info, company info, and then info for an  
administrative user.

The method looks like this:

def create  
@account = Account.create!(params[:account])  
@company = @account.companies.create!(params[:company])  
@user = @company.users.create!(params[:user])  
end

However, this inevitably fails on validation and ActionController comes  
back  
saying that “Validation failed: Username can’t be blank, First name  
can’t be  
blank, Last name can’t be blank, Email address can’t be blank”

However, values for user are present in the request parameters:

_Parameters_: {“company”=\>{“name”=\>“poop”, “account\_id”=\>29},  
“user”=\>{“password\_confirmation”=\>“poop”, “username”=\>“poop”,  
“company\_id”=\>29, “time\_zone”=\>“International Date Line West”,  
“first\_name”=\>“poop”, “password”=\>“poop”, “last\_name”=\>“poop”,  
“email\_address”=\>“poop”}, “account”=\>{“name”=\>“poop”, “url”=\>“poop”}}

I’ve tried using User.new(params[:user]) with the same results. The  
only  
thing that has given me something different is to loop through the  
key/values from params[:user]. I’m a bit stumped here, and any help is  
appreciated.

Thanks,

Jeremiah

Curiously enough, when I run this same sequence of code through  
script\console, I get the same error.

account = Account.create!(:name =\> “poop”, :url =\> “poop”)  
company = account.companies.create!(:name =\> “poop”)  
user = company.users.create!(:first\_name =\> “poop”, :last\_name =\>  
“poop”,  
:username =\> “poop”, :email\_address =\> “poop”, :password =\> “poop”,  
:password\_confirmation =\> “poop”)

produces

Here’s the code from the user model

cattr\_accessor :current\_user

attr\_accessor :password, :password\_confirmation  
attr\_accessible :password, :password\_confirmation

def hashed\_password=(pass)  
salt = [Array.new(6){rand(256).chr}.join].pack(“m”).chomp  
self.password\_salt, self.password\_hash = salt,  
Digest::SHA256.hexdigest(pass

- salt)  
end

Guess I didn’t read my own code close enough. I was blocking myself  
with  
attr\_accessible.
