  • Rails find all with association

    - by aaronrussell
    I have what I think is a very simple problem (famous last words)... I have a Category model that has_and_belongs_to_many Events. I want to construct a simple and efficient query that finds all categories that have 1 or more events. (using Rails 3) I'm sure I'm having a dumb moment here - any help appreciated :)

  • Create Rails model with argument of associated model?

    - by Kyle Carlson
    I have two models, User and PushupReminder, and a method create_a_reminder in my PushupReminder controller (is that the best place to put it?) that I want to have create a new instance of a PushupReminder for a given user when I pass it a user ID. I have the association via the user_id column working correctly in my PushupReminder table and I've tested that I can both create reminders & send the reminder email correctly via the Rails console. Here is a snippet of the model code: class User < ActiveRecord::Base has_many :pushup_reminders end class PushupReminder < ActiveRecord::Base belongs_to :user end And the create_a_reminder method: def create_a_reminder(user) @user = User.find(user) @reminder = PushupReminder.create(:user_id => @user.id, :completed => false, :num_pushups => @user.pushups_per_reminder, :when_sent => Time.now) PushupReminderMailer.reminder_email(@user).deliver end I'm at a loss for how to run that create_a_reminder method in my code for a given user (eventually will be in a cron job for all my users). If someone could help me get my thinking on the right track, I'd really appreciate it. Thanks!

  • Javascript not executing (I included format.js)

    - by Brandon
    I added format.js to my controller, yet I still cannot get the js in index.js.erb to execute when I view my index page. The only thing I can figure out is that it must be because of the model name. I had to add ActiveSupport::Inflector.inflections do |inflect| inflect.irregular 'business', 'businesses' end to my inflections.rb file...because my model is called Business. my views/js are located at views/businesses/* Please help before I pull my hair out! All I have in the index.js.erb file is: alert(1); Obviously the goal is that I will get an alert when I finally get the issue fixed, letting me know it is working.

  • What is the best place to store globals in Rails app?

    - by Nick Gorbikoff
    Hello. I was wondering if there is the best practice on where to store global settings in a rails app. What I mean by that is i.e: I have a few globals defined that may change, but not likely and it seems inappropriate to store them in DB since they are used so much. For instance I have SYSTEM_EMAIL & SYSTEM_EMAIL_SIGNATURE & SYSTEM_STORAGE_ROOT. Right now I keep them in environment.rb, but I'm not sure if this is the right palce to store them. Thank you

  • RSpec "undefined local variable or method `user'"

    - by Justin
    I have the following test written in RSpec: describe '#create' do ... it 'redirects users to profile page' do response.should redirect_to user_path(user) end ... ... And the following in my UsersController: def create @user = User.new(params[:user]) if @user.save redirect_to user_path(@user) end end Does anyone know why this is returning the following error: NameError: undefined local variable or method 'user' I also tried changing this to be root_url in both cases instead of user_path(user) and it gave a different error saying: Expected response to be a <:redirect>, but was <200> Does anyone know what the issue might be? I have double-checked my code and have seen similar questions posted online, but haven't been able to find a solution. Thanks in advance for any help!

  • what is the wrong with this spec and controller code?

    - by user1609468
    I'm trying to test an existing rails project with rspec. And I want to test a controller but getting an error which I can't solve :S Here is the my spec code ; require 'spec_helper' describe BriefNotesController do before(:all) do @customer=Factory(:customer) @project=Factory(:project_started, :owner => @customer) end context 'get :new' do it 'should redirect to login page for not signed in users' do get :new, :project_id => @project.id response.should redirect_to("/kullanici-girisi") end it 'should be success and render new brief note page for project owner' do sign_in @customer get :new, :project_id => @project.id response.should be_success end end end Here is the my controller code ; class BriefNotesController < ApplicationController before_filter :authenticate_user! before_filter :find_project def new @brief_note = @project.brief_notes.new end def create @brief_note = @project.brief_notes.build(params[:brief_note]) if @brief_note.save redirect_to brief_project_path(@project) else render :action => :new end end private def find_project @project = current_user.projects.find_by_cached_slug([params[:project_id]]) end end I think current_user.projects.find_by_cached_slug method don't work. So this is the error; Failures: 1) BriefNotesController get :new should be success and render new brief note page for project owner Failure/Error: get :new, :project_id => @project.id NoMethodError: undefined method `brief_notes' for nil:NilClass # ./app/controllers/brief_notes_controller.rb:6:in `new' # ./spec/controllers/brief_notes_controller_spec.rb:19:in `block (3 levels) in <top (required)>'

  • Accessing global variables in a flash[:notice]

    - by Trip
    This is deals_controller.rb. And it works like this, except two things. Not sure how to call Deal.count to add in my flash[:notice] . I get the hunch that its not calling something global. I need that contional statement back, as I'm pretty sure its responsible for actually adding the new @deal . So I assume my syntax is off. Do note, I added an extra 'end' when I uncomment this block. def create -# This will use the disclaimer_ids submitted from the check boxes in the view -# to add/delete deal.disclaimers entries to matched the list of checked boxes. @deal = Deal.new(params[:deal]) -# <------I Need this commented out IF statement back ------- -#if @deal.valid? && @organization.deals << @deal flash[:notice] = 'Your promotion is published! You may find it in the number 1 position of our #{deal.count} previously posted promotions. To see your promotion, click here."' respond_to do |format| format.html { redirect_to organization_deals_path(@organization) } format.js -# I Need this IF Statement Back! -#else -#@disclaimers = Disclaimer.all -#render :action = 'new' end end Thanks!

  • How do you deal with breaking changes in a Rails migration?

    - by Adam Lassek
    Let's say I'm starting out with this model: class Location < ActiveRecord::Base attr_accessible :company_name, :location_name end Now I want to refactor one of the values into an associated model. class CreateCompanies < ActiveRecord::Migration def self.up create_table :companies do |t| t.string :name, :null => false t.timestamps end add_column :locations, :company_id, :integer, :null => false end def self.down drop_table :companies remove_column :locations, :company_id end end class Location < ActiveRecord::Base attr_accessible :location_name belongs_to :company end class Company < ActiveRecord::Base has_many :locations end This all works fine during development, since I'm doing everything a step at a time; but if I try deploying this to my staging environment, I run into trouble. The problem is that since my code has already changed to reflect the migration, it causes the environment to crash when it attempts to run the migration. Has anyone else dealt with this problem? Am I resigned to splitting my deployment up into multiple steps?

  • Cannot translate date formats from rails form to mysql db

    - by Steve
    I have a simple search form in rails 3 that has two date fields. I'm having a problem getting these dates into my mysql db. I've tried using the american_date gem, specifying date formats in my initializers, in the config/locales/en.yml file, and directly on the date on the date fields themselves. Currently, I'm setting the rails-approved date format in the view - <%= f.text_field :depart_date, :value=> Date.today.strftime('%Y-%m-%d') %> The dateformat in my DB is also YYYY-mm-dd, so things should be going smoothly. The console tells me that the two date fields are both class = "Date" I think I've found the disconnect. From the logs - Started POST "/searches" for 127.0.0.1 at 2013-10-30 17:43:26 -0400 Processing by SearchesController#create as HTML Parameters: {"utf8"=>"v","search"=>{"depart_date"=>"2013-10-30", "return_date"=>"2013-11-09"} ?[1m?[35m (0.0ms)?[0m BEGIN ?[1m?[36mSQL (0.0ms)?[0m ?[1mINSERT INTO `searches` (`depart_date`,`return_date`) VALUES ('2013-30-10','2013-09-11')?[0m ?[1m?[35m (2.0ms)?[0m COMMIT Note that the month and day values are switched in the insert statement. How can I prevent this from happenening?

  • Removing "duplicate objects"

    - by keruilin
    Let's say I have an array of objects from the same class, with two attributes of concern here: name and created_at. How do I find objects with the same name (considered dups) in the array, and then delete the duplicate record in the database. The object with the most-recent created_at date, however, is the one that must be deleted.

  • Rails 2.3.8 Compound condition

    - by Michael Guantonio
    I have a rails query that I would like to run. The only problem that I am having is the query structure. Essentially the query looks like this queryList = model.find(:all, :conditions => [id = "id"]) #returns a query list #here is the issue compound = otherModel.find(:first, :select => "an_id", :conditions => ["some_other_id=? and an_id=?, some_other_id, an_id]) Where an_id is actually a list of ids in the query list. How can I write that in rails to basically associate a single id to a list that may contain ids...

  • How can I load a div in rails in response to clicks on another div?

    - by mmr
    I'm very new to Rails (and web) programming, so I'm not even sure what technology I should be looking for for this. I've downloaded and run through the first five chapters of the Rails tutorial, but now have a very simple request. On the left hand side of a web page, I will have a table. If the user clicks on an element in that table, I want to have the right hand side of the page show something new. I already have a page to display the table, viz: <div class="center hero-unit"> <div class="container"> <h2>2012 Yearly Report</h2> <div class="row-fluid"> <div class="span12"> <div class="span4"> <table border="1"> </table> </div> <div class="span6"> <!-- load stuff here based on what someone clicks on in the table --> </div> </div> </div> </div> </div> And I'm using bootstrap layouts to display everything. I just don't understand how to change the contents of the 'span6' div based on user behavior in 'span4'.

  • Should I split this model and table?

    - by regedarek
    I would like to create simple ResumeBank app. Issue: As user I would like to add only two Resumes. Forms for this both Resumes are different with only two fields. Resumes have 12 the same attributes but 2 are diferent. Question: Should I split that Resume model and tables to ex: PolishResume and EnglishResume, polish_remsumes and english_remsumes? Or maybe should I use STI and create PolishResume < Resume and use one table. What are disadvantages of splitting option?

    I've found an old plugin called acts_as_habtm_list - but it's for Rails 1.0.0. Is this functionality built in acts_as_list now? I can't seem to find any information on it. Basically, I have an artists_events table - no model. The relationship is handled through those two models specifying :has_and_belongs_to_many How can I specify order in this situation?

    I want to change my layout based on whether or not the current user is an admin. So I made a simple method to check if current user is admin, I then call that method in application controller. I keep getting the following error: undefined method `is_admin?' for ApplicationController:Class My code looks like this: class ApplicationController < ActionController::Base protect_from_forgery helper_method :current_user, :is_admin? if is_admin? layout 'admin' end ..... protected ..... def is_admin? if current_user.user_role == 'admin' return true end end end How should I be doing this?

  • Information not getting into the controller from the view. (authologic model)

    - by Gotjosh
    Right now I'm building a project management app in rails, here is some background info: Right now i have 2 models, one is User and the other one is Client. Clients and Users have a one-to-one relationship (client - has_one and user - belongs_to which means that the foreign key it's in the users table) So what I'm trying to do it's once you add a client you can actually add credentials (add an user) to that client, in order to do so all the clients are being displayed with a link next to that client's name meaning that you can actually create credentials for that client. So in order to do that I'm using a helper the link to helper like this. <%= link_to "Credentials", {:controller => 'user', :action => 'new', :client_id => client.id} %> Meaning that he url will be constructed like this: http://localhost:3000/clients/2/user/new By creating the user for the client with he ID of 2. And then capturing the info into the controller like this: @user = User.new(:client_id => params[:client_id]) The weird thing is that EVERY other information BUT the client id it's getting passed and the client ID should be passed with the params[:client_id]. Any ideas? Perhaps it may have something to do with the fact that model User has "acts_as_authentic" because I'm using authologic for it? Model: class User < ActiveRecord::Base acts_as_authentic belongs_to :client end Controller: def create @user = User.new(:client_id => params[:client_id]) if @user.save flash[:notice] = "Credentials created" else flash[:error] = "Credentials failed" end end View: <% form_for @user do |f| % <p> <%= f.label :login, "Username" %> <%= f.text_field :login %> </p> <p> <%= f.label :password, "Password" %> <%= f.password_field :password %> </p> <p> <%= f.label :password_confirmation, "Password Confirmation" %> <%= f.password_field :password_confirmation %> </p> Let me know if this is sufficient or need more. <%= f.submit "Create", :disable_with => 'Please Wait...' %> <% end %>

  • Camping: Return user to recent entries, but keep errors

    - by echoback
    Users can view a specific entry in my webapp with a URL. /entry/8, for example. If an entry doesn't exist, "Entry not found" gets appended to @messages and I render an error page. I'd like to redirect the user to /recent, but I can't figure out a good way to keep the error message around to be displayed. There are other actions that need to take place in the Recent controller, so I can't just duplicate the query and render :posts.

  • Rails date format in form field

    Hello I'd like my dates in the mm/dd/year format in text fields. However, they currently displays as 2010-03-26. Is there a global setting I can set to change this? I tried the following, which seems to update the .to_s method, but form fields stay the same. ActiveSupport::CoreExtensions::Date::Conversions::DATE_FORMATS.merge!(:default => '%m/%d/%Y') Thanks
