Model validations failed..(as there are two model used)

i have used two model club and user in one form but validation doesn’t
call for child model even i have written validates_associated :user in
parent model…when i fill information for user and don’t fill for club
then validations are called for club but user is saved which i don’t
want…so please help me…

Thanks,
Preksha.

Hi Preksha,

Are you using ‘.build’ parameters.

(e.g. @club = Club.new
@user = @club.users.build(params[:user]) for one(club) to many(users)
relations)

and in view page

specify <%= error_messages_for :club, :user%>

Hope this might help.

hi Saurabh

there is one-to-one relationship between club and user…
and in club model i have used both
validates_associated :user
validates_presence_of :user_id, :message => nil
then also it is not working…

and in view page i already specified error_messages_for…

Ok,

Try this,

def create
@club = Club.new(params[:club])
@user = @club.build_user(params[:user])

if @club.valid?
@club.save
end

end

hi Saurabh

but i don’t need to write @user.save any where?

This will check if both are valid or not and save them at same time, if
any one of them is invalid nothing gets saved.

Please let me know which controller are you trying to use? (Uses or
Clubs)

user controller

user controller

i wrote that code in users_controoler.rb file but now validations don’t
call for any one of them.

Then try this,

in users_controllers.rb

def create
@user = User.new(params[:user])
@club = @user.build_club(params[:club])

if @user.valid?
@user.save
end

end

Note: it is not required to specify @club.save because ‘.build’ will
automatically do that for you.

in model/user.rb
validates_associated :club

but user_id is foreign key in club table…so will it ok to write
validates_associated :club in user model?

i tried for that code but now following error occurs:
NoMethodError in UsersController#create

undefined method `build_club’ for #User:0xb5c97e70

Can you share your model?

yeah sure…

club.rb file:

#PHONE_NO_MAX_LEN = 15

validates_associated :user
#validates_presence_of :user_id, :message => nil

prevents a user from submitting a crafted form that bypasses

activation

anything else you want your user to change should be added here.

#validates_associated :club

Authenticates a user by their login name and unencrypted password.

Returns the user or nil.
def self.authenticate(login, password)
u = find_in_state :first, :active, :conditions => {:login => login}

need to get the salt

u && u.authenticated?(password) ? u : nil

end

Encrypts some data with the salt.

def self.encrypt(password, salt)
Digest::SHA1.hexdigest("–#{salt}–#{password}–")
end

Encrypts the password with the user salt

def encrypt(password)
self.class.encrypt(password, salt)
end

def authenticated?(password)
crypted_password == encrypt(password)
end

def remember_token?
remember_token_expires_at && Time.now.utc <
remember_token_expires_at
end

These create and unset the fields required for remembering users

between browser closes
def remember_me
remember_me_for 2.weeks
end

def remember_me_for(time)
remember_me_until time.from_now.utc
end

def remember_me_until(time)

self.remember_token_expires_at = nil

Returns true if the user has just been activated.

now i wrote this code in users_controller:

@user = User.new(params[:user])
@club = @user.build_club(params[:club])

if @user.valid?
@user.save
end

and in user model this code:

has_one :club
validates_associated :club

then also validations didnt called…

Have you commented the line

in club.rb
validates_associated :user
