  • Shedule tasks question

    - by gabac
    Hi everyone I have a though question :) Let's say you get some data which is due at a certain point int the future. You get A saying my task is due in 1h and other which says his task is due in 1.5h. The information is collected on your server. In which programming language or even how would solve that? So task a will be executed in 1h, task B in 1.5h. I read something about java scheduler but I'm not yet sure if this is the right way. What are ur ideas? Cheers

  • Rails 3 many-to-many query on includes or joins

    - by Myat
    I have three models User, Activity and ActivityRecord. class User < ActiveRecord::Base # Include default devise modules. Others available are: # :token_authenticatable, :confirmable, # :lockable, :timeoutable and :omniauthable devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable, :validatable # Setup accessible (or protected) attributes for your model attr_accessible :first_name, :last_name, :email, :gender, :password, :password_confirmation, :remember_me # attr_accessible :title, :body has_many :activities has_many :activity_records , :through=> :activities end class Activity < ActiveRecord::Base attr_accessible :point, :title belongs_to :user has_many :activity_records end class ActivityRecord < ActiveRecord::Base attr_accessible :activity_id belongs_to :activity scope :today, lambda { where("DATE(#{'activity_records'}.created_at) = '#{Date.today.to_s(:db)}'")} end I would like to query all activities for a user together with the count for their respective activity records for today.

  • New to Git. Made a big mistake with git commit and ended up at an older commit

    - by Ramario Depass
    I'm new to Git and I've made a huge mistake. Git kept prompting me with git - rejected master -> master (non-fast-forward). But, I still committed by using: --force This was disastrous, the whole project changed back to the stage it was at about a week ago. I've lost so many changes. I seem to have been pushed back to an earlier commit. Is there anyway I can get back to one of my newer commits? As I have made an enormous amount of changes and need to get them back. Thanks.

    - by Nick
    I was trying to write a simple array flatten method, but it does not work using instance variable. It works only using class variables. Can anyone tell me why? and how to make it work using instance variables. class Array @y = [] def flatten_array self.each do |x| if x.class.to_s != 'Array' @y << x else x.flatten_array end end return @y end end a = [1,2,3,4,5] b = [6,7,8] c = [9,10] a1 = [12,13,a,b,c] puts a1.inspect b1 = a1.flatten_array puts b1.inspect

  • has_many in rails

    - by user363243
    I have a 'users' table which stores all of my websites users, some of which are technicians. The users table has a 'first_name' and 'last_name' field as well as other fields. The other table is called 'service_tickets' which has a foreign key from users called technician_id. This gives me a real problem because when I am looking at the service_tickets table, the related user is actually a technician. That's why the service_tickets table has a technician_id and not a user_id field. I am trying to accomplish something like this: t = service_ticket.find_by_id(7) t.technician.first_name # notice how I don't do t.user.first_name Is this possible in rails? I can't seem to get it to work... Thank you for your help!

  • Wrapping <%= f.check_box %> inside <label>

    - by Ben Scheirman
    I have a list of checkboxes on a form. Due to the way the CSS is structured, the label element is styled directly. This requires me to nest the checkbox inside of the tag. This works in raw HTML, if you click on the label text, the state of the checkbox changes. It doesn't work with the rails <%= f.check_box %> helper, however, because it outputs a hidden input tag first. In summary, <label> <%= f.check_box :foo %> Foo </label> this is the output I want: <label> <input type="checkbox" ... /> <input type="hidden" ... /> Foo </label> ...but this is what rails is giving me: <label> <input type="hidden" ... /> <input type="checkbox" ... /> Foo </label> So the label behavior doesn't actually work :(. Is there any way to get around this?

  • Rails: attribute_changed?

    - by Sam
    I have a model that has an amount and I'm tracking to see if this amount is changed with a Model.amount_changed? with a before_save which works fine but when I check to see amount_was and amount_change? it only returns the updated amount not the previous amount. And all this is happening before it is save. It knows when the attribute is changed but it will not return the old value. Ideas?

  • Complex Forms Generating Error

    - by user1648020
    I am working on an application that allows students to create a catalog of courses they are taking for a semester. I have created models for user; course; subject and category. Users can have many courses. Each course can have many subjects and categories. The tables for courses, subjects and categories include the following: Catalog: user_id; subject_id, category_id and course_id Courses: user_id; coursedetail_id Coursedetail: name; description Subject: name; description Category: name; description The idea is that an Admin can create a list of courses; subjects and categories and that the user can select the courses they want to add to their catalog. I have seperated courses and coursedetails because I envision that the coursedetails will grow overtime and the courses table will allow me to join the user_id and cousres details to rreport on if necessary. I attempted to follow Ryan's railscast on Complex Forms thinking that that I should use a complex form and has many relationship to get things working -- but I get an error in the catalog controller - cannot locate catalog_id which I know is in the table. I am now not sure if complex forms is the way to go or I should be looking at another direction to get the appropriate form in place. Any assistance would be appreciated.

  • nested has_many

    - by dorelal
    I am using Rails 2.3.5. Class User < ActiveRecord::Base has_many :phones end class Phone < ActiveRecord::Base has_many :frequency_bands end I want to get all the frequency_bands for a user. I know I can write a method def freq_bands for User but I would like to know if it is possible to have has_many freq_bands for a User. In this way I can chain the call. What I would like to have is class User < ActiveRecor::Base has_many :frequence_bands, :through => phones end I think it is possible to have nested has_many using this plugin http://github.com/ianwhite/nested_has_many_through However if possible I would like to avoid using another plugin and rely solely on rails.

  • Proper way to use before_create

    - by ruevaughn
    Pretty basic question here, I need to write a before filter on my Category model, to ensure that the depth never reaches more than 2. Here is what I have so far. app/models/category.rb before_create :check_depth def check_depth self.depth = 1 if depth > 2 end I need it instead of setting depth to 1, just to return a error message, but I can't even get this current setup to work, I get the error undefined method `>' for nil:NilClass So, instead of setting the depth to one like I'm trying to do how would I send an error instead? And any help getting the current function working for informational purposes? Thanks in advance

  • Rails form not creating object

    - by user2136807
    I have created a simple form to create an instance of a modle and for some reason it is not calling the create method in the controller. Here is the form code: <% @house.mates.each do |mate| %> <p><%= mate.name %></p> <% end %> <h2>Add a new mate:</h2> <%= form_for @mate do |f| %> <p><%= f.label "Name" %> <%= f.text_field :name %> <%= f.hidden_field :house_id %> </p> <%= f.submit "Submit", :action => :create %> <% end %> Here is the controller code: class MatesController < ApplicationController def new @mate = Mate.new end def create @mate = Mate.new(params[:mate]) @mate.save redirect_to house_path(current_house) end end There is a many to one relationship between the Mate model and the House model... I am fairly new to rails but I have made other apps with similar forms, and I have never had this problem before. I can create and save Mate objects in the console, and I am not getting any errors, so it seem that somehow the controller method is not being called. Any help is much appreciated!
