rails post parameters show but not inserted - ruby-on-rails-3

Question

I'm creating a small app in Rails 3.2.13, using bootstrap-sass gem.
I have the following situation:
My 'sign_up' controller has and 'index' action that creates a user like this:
#sign_up controller
def index
#user = User.new
end
Now, in my index.html.erb i have the form:
# sign_up controller => index.html.erb
<%= form_for #user, :html => {:class => 'form-horizontal'} do |f| %>
<div class = 'control-group'>
<%= f.label :username, :html => {:class => 'control-label'} %>
<%= text_field_tag :username, nil, :placeholder => 'Username' %>
</div>
<div class = 'control-group'>
<%= f.label :email, :html => {:class => 'control-label'} %>
<%= email_field_tag :email, nil, :placeholder => 'Email' %>
</div>
<div class = 'control-group'>
<%= f.label :password, :html => {:class => 'control-label'} %>
<%= password_field_tag :password, nil, :placeholder => 'Password' %>
</div>
<div class = 'control-group'>
<%= f.label :confirm_password, :html => {:class => 'control-label'} %>
<%= password_field_tag :confirm_password, nil, :placeholder => 'Confirm' %>
</div>
<%= f.submit 'Create', :class => 'btn btn-primary'%>
This will POST to users_controller, calling the create action:
# users controller
def create
#user = User.new(params[:user])
respond_to do |format|
if #user.save
format.html { redirect_to #user, notice: 'User was successfully created.' }
format.json { render json: #user, status: :created, location: #user }
else
format.html { render action: "new" }
format.json { render json: #user.errors, status: :unprocessable_entity }
end
end
end
The problem is: the #user is saved, but the parameters are lost!
In the console log:
Started POST "/users" for 127.0.0.1 at 2013-05-29 12:14:47 -0300
Processing by UsersController#create as HTML
Parameters: {"utf8"=>"✓", "authenticity_token"=>"wI5sNQV/lkn8GtYv5YkRLZ6HzxPg5MtoVXuarLulv30=", "username"=>"nonickname", "email"=>"no#bar.com", "password"=>"[FILTERED]", "confirm_password"=>"[FILTERED]", "commit"=>"Create"}

SQL (0.9ms) INSERT INTO "users" ("admin", "created_at", "email", "password_hash", "password_salt", "updated_at", "username") VALUES (?, ?, ?, ?, ?, ?, ?) [["admin", nil], ["created_at", Wed, 29 May 2013 15:14:47 UTC +00:00], ["email", nil], ["password_hash", nil], ["password_salt", nil], ["updated_at", Wed, 29 May 2013 15:14:47 UTC +00:00], ["username", nil]]
(148.9ms) commit transaction...
Why that happens, and how can i fix this? I know the form should be a users_controller domain(i plan to fix that), but it doesn't seem to be the problem!
Thanks for any help!

Answer 1

I'll try to help you here as much as I can. Have a look at the console when I create a comment:
Started POST "/companies/1/comments" for 127.0.0.1 at 2013-05-29 20:06:02 +0300
Processing by CommentsController#create as JS
Parameters: {"utf8"=>"✓", "authenticity_token"=>"+J+ewToARuBybidK79V/3cFdX6=", "comment"=>{"content"=>"Lorem ipsum..."}, "commit"=>"Add Comments", "company_id"=>"1"}
(0.1ms) BEGIN
SQL (0.2ms) INSERT INTO `comments` (`commentable_id`, `commentable_type`, `content`, `created_at`, `updated_at`, `user_id`) VALUES (1, 'Company', 'Lorem ipsum...', '2013-05-29 17:06:02', '2013-05-29 17:06:02', 2)
(42.7ms) COMMIT
now when I say on conrtoller #comment = Comment.new(params[:comment]) means it will look for this line "comment"=>{"content"=>"Lorem ipsum dolor sit amet, ..."}
that means params[:comment] in my case is content, parameters are being sent as a hash and in your case you must have something like:
"user"=>{authenticity_token"=>"wI5sNQV/lkn8GtYv5YkRLZ6Hzx=", "username"=>"nonickname", "email"=>"no#bar.com", "password"=>"[FILTERED]", "confirm_password"=>"[FILTERED]"}`
in your console logs. I've looked a few times in your console logs and didn't see the user there and you can't call #user = User.new(params[:user]) as long as it is missing.
about the form, if you are using:
<%= form_for #user, :html => {:class => 'form-horizontal'} do |f| %>
you could use f to build your fields and write less this way
<%= form_for #user, :html => {:class => 'form-horizontal'} do |f| %>
<div class = 'control-group'>
<%= f.label :username, :html => {:class => 'control-label'} %>
<%= f.text_field :username, :placeholder => 'Username' %>
</div>
<div class = 'control-group'>
<%= f.label :email, :html => {:class => 'control-label'} %>
<%= f.email_field :email, :placeholder => 'Email' %>
</div>
<div class = 'control-group'>
<%= f.label :password, :html => {:class => 'control-label'} %>
<%= f.password_field :passwor, :placeholder => 'Password' %>
</div>
<div class = 'control-group'>
<%= f.label :confirm_password, :html => {:class => 'control-label'} %>
<%= f.password_field :confirm_password, :placeholder => 'Confirm' %>
</div>
<%= f.submit 'Create', :class => 'btn btn-primary'%>

Ok, it's solved!
The problem was the bootstrap form, i need to set the name attribute:
...
<div class = 'control-group'>
<%= f.label :email, :html => {:class => 'control-label'} %>
<%= email_field_tag :email, nil, :name => 'user[email]', :placeholder => 'Email' %>
</div>
...
Thanks!
