Missing will_paginate

[THEBIGO]

I’m not sure why i am having this problem but when i execute a call to
the calls controller from a link

<%= link_to_unless_current 'My Call Book', { :controller => "calls", :action => "index" } %>

::

I get the following error

NoMethodError in CallsController#index

undefined method `_of’ for #Class:0x2517c1c

part of my CallsController is

class CallsController < ApplicationController
before_filter :login_required, :only => [ :index, :new, :edit]

def index
@calls = Call.find(:all)
@recent_calls = @current_user.calls.find(:all)
@recent_calls = @current_user.calls.search(params[:search],
params[:page])
end

def list
@calls = @current_user.calls.find(:all)
end

def show
@call = Call.find(params[:id])
end

And my call model is

class Call < ActiveRecord::Base
belongs_to :user
has_many:visits, :dependent => :destroy
has_many:visits do
def latest
find :all, :order => ‘id DESC’, :limit => 3
end

def all_latest
  find :all, :order => 'id DESC'
end

end

def self.search(search, page)
paginate :per_page => 4, :page => page,
:conditions => [‘name like ?’, “%#{search}%”],
:order => ‘name’
end

end

It says in the error message `method_missing_without_paginate’

I have will_paginate installed in rails as a gem and it shows up in my
gem list. Any help to a beginner working on first real app after may
books would be appreciated

Thanks Owen

The problem is in your controller action

def index
@calls = Call.find(:all)
@recent_calls = @current_user.calls.find(:all)
@recent_calls = @current_user.calls.search(params[:search],
params[:page])
end

first, you are declaring @recent_calls twice, the first one
(@recent_calls = @current_user.calls.find(:all)) will never work when
the second is there.

next, when you declare a method self.search in the class Call, you
call it in the class!! so Call.search(params[:search], params[:page])
willl return an array of calls. (Note: it will return them for ALL
users, not just the current.

Third, you are calling a method on class Array (which is what
@current_user.calls returns) when you defined that method in the class
Call.

If you want to get a list of call objects from a user (i assume user
has_many :calls, and call belongs_to :user) with a name like something
and paginated. id do it like such:

def index
@recent_calls = @current_user.calls.paginate :per_page => 4, :page
=> params[:page],
:conditions => [‘name like ? AND user_id = ?’, “%#{params[:search]}
%”, @current_user.id],
:order => ‘name’
end

if you use the method more than twice, then put it in the class, but
you would also need to pass the user id.

good luck

Thank you so much Wolas for your reply and your suggestion got rid of
my undefined mehod error And I coppied and pasted your suggestion but
I now get the following error - I am not sure where to correct it

looks the email line wrapped it in a bad way:

@recent_calls = @current_user.calls.paginate :per_page => 4, :page
=> params[:page],

should be all on one line. (if you do put in line breaks put them
after a ,)

Thank you again Fred and Wolas but now I am back to my undefined
method and the following error

NoMethodError in CallsController#index

undefined method `_of’ for #Class:0x2355ca8

/Library/Ruby/Gems/1.8/gems/activesupport-2.0.2/lib/active_support/

My index action is now
def index
@recent_calls = @current_user.calls.paginate :per_page =>
4, :page => params[:page],
:conditions => [‘name like ? AND user_id = ?’,
“%#{params[:search]}
%”, @current_user.id],
:order => ‘name’

end

Notice the method-missing-without_paginate. Originally I have the
pagination in my model as post one shows per Ryan B. and it worked
in another version of
this app so that is why it wasn’t in my original index action. I had
moved it to the model.

I don’t understand why the method_missing_without_paginate is there as
my gem list shows I have the latest will_paginate and I am using rails
2.0.2

Any other suggestions?? Thanks in advance

Still havn’t figured out where the NoMethodError is from. Says
wiil_paginate is missing
and then the log file shows something about rb:23 in my call model.
Does that mean line 23
in the model? Any help please for a person in first year rails
programing?

Thanks in advance - Owen

[THEBIGO]

look in line 23 of the model Call yes

[THEBIGO]

Thanks for the reply. My model is
class Call < ActiveRecord::Base
belongs_to :user
has_many:visits, :dependent => :destroy
has_many:visits do
def latest
find :all, :order => ‘id DESC’, :limit => 3
end

    def all_latest
        find :all, :order => 'id DESC'
    end

    #def self.search(search, page)
    #    paginate :per_page => 4, :page => page,
    #    :conditions => ['name like ?', "%#{search}%"],
    #    :order => 'name'
    #end
end

20 def self.search(search, page)
21 paginate :per_page => 4, :page => page,
22 :conditions => [‘name like ?’, “%#{search}%”],
23 :order => ‘name’
end

ALL_FIELDS = %w(name address age area sex notes)
VALID_SEX = ["Male", "Female"]
validates_presence_of :name, :address, :age, :area
validates_inclusion_of :sex,
                        :in => VALID_SEX,
                        :message => "must be male or female"

end

And line 23 is in the def for self.search conditions where I have

:order => ‘name’ so I am not sure what is wron there

[THEBIGO]

thanks all for your help but I found my error and it involved an extra
space in a rails method
and the fact that when I changed some of the deffinitions in the model
when I refrenced them I refrenced the old terms. thanks again - Owen
