problem: if i upload promotions photo showing correct. But same photo display promotion_menus also. what is the wrong? can you help me?
You have the same attachment path for both models:
:path => ":attachment/:id/:style.:extension"
In both models attachment name is photo.
Change attachment name or path in one of models.

Ok, this is a triple table query, and I am very very confused in how to go about this, let along construct it.
I'm trying to find all the tutoring session tied to a specific email address.
The tables information is listed down beneath.
User, TutorSession, & SessionUser.
TutorSession belongs to User
Users has many SessionUser
Here are the attributes of each table:

add_index "session_users", ["tutor_session_id"], :name => "index_session_users_on_session_id"
add_index "session_users", ["user_id"], :name => "index_session_users_on_user_id"
EDIT
I made a mistaking in stating how the tables were related to each other. Sorry, my head is somewhere else.
SessionUser belongs to both user and tutor_session
TutorSession has many session_users
User has many session_users
Not sure what your model looks like, but should be as easy as:
User.find_by_email('someone#example.com').tutor_sessions
For this to work your models should look something like this:
class User < ActiveRecord::Base
has_many :sessions, :class_name => SessionUser
has_many :tutor_sessions, :through => :sessions
end
Basically, this query:
SELECT s.*
FROM users u
JOIN session_user su ON u.id = su.user_id
JOIN tutor_session s ON s.id = su.tutor_session_id
WHERE u.email = 'foo#bar'
My sign up page has login. email, password, password_confirm and company fields . All of them are supposed to be mandatory but when i click on sign up it is not checking if any fields except password and password_confirm are blank!!

The problem is that you pass an if option to your validation which also applies to the presence validation. Take for example the following
validates :login,
:presence => true,
:length => { :within => 3..40},
:uniqueness => { :case_sensitive => false },
:format => { :with => /^([a-z_0-9\.]+)$/i },
:on => :create,
:if => :is_login_entered?
is_login_entered? is called when validating the presence of login which conflicts with the validation which is why the validation is skipped. Change your validation to
validates :login, :presence => true, :on => :create
validates :login,
:length => { :within => 3..40},
:uniqueness => { :case_sensitive => false },
:format => { :with => /^([a-z_0-9\.]+)$/i },
:on => :create,
:if => :is_login_entered?
This way, the other validations will only run if a login is present.
On rails console i am trying to call

which returns me some object like

but when i tried to loop over the object like
#invoice.each { |t| p t.number }
i got nil,but database contains data for invoice.

Can anyone please help me with this?
Thanks in advance.
I'm not exactly sure of how to do this with Ruby On Rails, but if your Invoice objects (nodes) are in a lucene full text index, you could use a Cypher query to return all Invoices.
Something like:
START invoices=node:Invoices('name: *') RETURN invoices;
Paperclip gem 3.0.4
When I use flat Paperclip definition in Model (UserDetail has an avatar):
has_attached_file :avatar, :styles => {:medium => "300x300>", : :thumb => "64x64#" }
All images are created in correct proportions.
When I use a custom processor through lambda ( http://www.matthuggins.com/articles/rotating-paperclip-image-attachments-in-rails ):
has_attached_file :avatar, :processors => [:rotator], :styles => lambda { |a| {
:thumb => { :geometry => '64x64#', :rotation => a.instance.rotation, },
:medium => { :geometry => '300x300>', :rotation => a.instance.rotation, }, } }
The image is rotated by the specified amount but all images stay at the same size and proportions as the :original.
Is :geometry the right parameter? Has this changed in later version of Paperclip (I'm unsure of the version of Paperclip used in the web example)?
Any pointers gratefully received
Regards
Peter
one proc per style:
has_attached_file :avatar,
:processors => [:rotator],
:styles => {
:thumb => Proc.new { |a| { :geometry => '64x64#', :rotation => a.instance.rotation } },
:medium => Proc.new { |a| { :geometry => '300x300>', :rotation => a.instance.rotation } }
}
I want to validate the email only if the email has been entered.
I tried the following:
validates :email, :presence => {:message => "Your email is used to save your greeting."},
:email => true,
:if => Proc.new {|c| not c.email.blank?},
:uniqueness => { :case_sensitive => false }
However this does not work as it stops error messages from showing when the email is left blank.
How can I validate the presence of the email when it is missing and ONLY validate the format when it has been entered?
This should do the trick.
validates :email,:presence => {:message => "Your email is used to save your greeting."}, :allow_blank => true,:uniqueness => { :case_sensitive => false }
Use:allow_blank => true or :allow_nil => true, :if => :email?
edit: fix typo.
You can write custom validation function:
class Model < ActiveRecord::Base
validate :check_email
protected
def check_email
if email.blank?
validates :email, :presence => {:message => "Your email is used to save your greeting."}
else
validates :email,
:email => true,
:uniqueness => { :case_sensitive => false }
end
end
end
or divide your validator into 2 separate validators with conditions:
validates :email,
:presence => {:message => "Your email is used to save your greeting."},
:if => Proc.new {|c| c.email.blank?}
validates :email,
:email => true,
:uniqueness => { :case_sensitive => false }
:unless => Proc.new {|c| c.email.blank?}
you can validate format if no precense required
:allow_nil => true
