Newbie Question: Lets be straightforward with form building.

Ok guys,

Rails is awesome.  So awesome that while I''m in awe of how easy it is  
to do the PITA CRUD work I normally have to code that I don''t  
understand how to do the basics of working with forms.

Here is my ordeal.  I want to add a password confirmation field to my  
form.  Then I want to validate that the confirmation password does in  
fact match my submitted password.


Here is a snippet code in my add_user controller...

     <label>Username:</label>
     <%= text_field("user", "name") %>

     <label>Password:</label>
     <%= password_field("user", "password") %>

     <label>Confirm:</label>
     <%= password_field("user", "confirm_password") %>

below is the error that I get thrown.  I know I''m not creating the  
field the right way becuase I''m associating it with the User model.   
What should I do?  This field is significant but it won''t need to be  
stored in the database.

Also, how would I access this parameter from the controller or would  
I check it in the User model?

NoMethodError in Login#add_user

Showing /login/add_user.rhtml where line #18 raised:

undefined method `confirm_password'' for #<User:0x24eda38>


Extracted source (around line #18):

15:     <%= password_field("user", "password") %>
16:
17:     <label>Confirm:</label>
18:     <%= password_field("user", "confirm_password")
%>
19:
20:     <div class="clear"></div>
21: </fieldset>

Re: Newbie Question: Lets be straightforward with form building.

An easy way to work around this would be to make ''password''
and
''confirm_password'' non-db attributes of the user model, and
have a
''pass'' field in the database for ActiveRecord to store.

Then have the model validate and compare ''password'' and 
''confirm_password'', store ''pass'' in the db,
and wipe ''password'' and
''confirm_password'' (so they don''t get sent back to
the client).

That''s roughly how we do it on the brainguppy.com signup form.

I hope this is fairly clear. Cheers,

Ben

Re: Newbie Question: Lets be straightforward with form building.

Looks like you can rename the confirmation field password_confirm and
then use the validates_confirmation_od method

Re: Newbie Question: Lets be straightforward with form building.

Wow that''s amazing!!  I''m still having trouble though.. using
this
method brings up no errors... even if the passwords don''t match.  Hmmm.

Re: Newbie Question: Lets be straightforward with form building.

Hi Jim,

I''d suggest two changes:

In your model add the following lines after the class declaration:

class User < ActiveRecord::Base

  attr_accessor :password_confirm
  validates_confirmation_of :password

  [...more stuff here...]
end

and then in the form change ''confirm_password'' to
''password_confirm''.


 From the controller you can then create a new User object via:

u = User.new(params[:user])

and then the validation will run automatically and highlight any form 
entry errors on the page if you do:

if u.save
	#save succeeded
	redirect_to :action => ''login_successful''  #your action
here
	return
else
	#save failed, re-render the original form w/ error messages
	render :action => ''loginpage''  #your action here
	return
end

The ''validates_confirmation_of'' will automatically check to
see if
''password'' and ''password_confirm'' are equal
during User.save.

The ''attr_accessor'' method will create a non DB backed
attribute as part
of the User class.

So that''s the DRY way to do it - but that also means the form fields
and
the model have to line up with each other.

If you want to go the manual route and fill in the user object by 
yourself, change the ''text_field'' and
''password_field'' helper calls to
''text_field_tag'' and ''password_field_tag''
calls.

Then you can simply access the form field names via
''params[:fieldname]''

(e.g. u.password = params[:password])

Re: Re: Newbie Question: Lets be straightforward with form building.

Thanks San!

My inexperience really shows.. I''m just waiting for things to come  
together for me the more  I work with this.  I''m still not at the  
point where I can just think something and code it out like I do in  
PHP but I''m getting there.  And the end result is a lot nicer in  
rails :D
