Hi…
i have a auto complete field for my authority_id field.authority_id
field is not mandatory.if the user not fills it will take the default
authority id as value.
but i want to validate if the user enters invalid authority name into
the auto complete text box…
i can do this in my controller…
but how can i implementd as modal validation.
pls help on this
below is my controller side implementation
#if autority text box is empty?
if params[:user_info][:login].empty?
@user = UserInfo.find_by_login(‘admin’)
@company.authority_id = @user.id
else
authority = UserInfo.find_by_login(params[:user_info][:login])
if authority.nil?
flash[ :error ] = “*Please Enter valid Authority name”
else
@company.authority_id = authority.id

Hi newb!

There’s a validation called validates_associated which checks if an
assosciated object is also valid.

So in company, you could add

validates_associated :authority :unless => lambda { |comp|
comp.authority_id.nil? }

This will check if the associated authority is a valid one provided the
company’s authority_id is not nil
