• Installing and using acts-as-taggable-on

  - by seaneshbaugh

  This is going to be a really dumb question, I just know it, but I'm going to ask anyways because it's driving me crazy. How do I get acts-as-taggable-on to work? I installed it as a gem with gem install acts-as-taggable-on because I can't ever seem to get installing plugins to work, but that's a whole other batch of questions that are all probably really dumb. Anyways, no problems there, it installed correctly. I did ruby script/generate acts_as_taggable_on_migration and rake db:migrate, again no problems. I added acts_as_taggable to the model I want to use tags with, started up the server and then loaded the index for the model just to see if what I've got so far is working and got the following error: undefined local variable or method `acts_as_taggable' for #. I figure that just means I need to do something like require 'acts-as-taggable-on' to my model's file because that's typically what's necessary for gems. So I did that hit refresh and got uninitialized constant ActiveRecord::VERSION. I'm not even going to pretend to begin to know what that means went wrong. Did I go wrong somewhere or there something else I need to do. The installation instructions seem to me like they just assume you generally know what you're doing and don't even begin to explain what to do when things go wrong.

• Database not completely updated in rails migration

  - by Aatish Sai

  I am new to Ruby on Rails. I have a migration called create user class CreateUsers < ActiveRecord::Migration def change create_table :users do |t| t.column :username, :string, :limit => 25, :default => "", :null => false t.column :hashed_password, :string, :limit => 40, :default => "", :null => false t.column :first_name, :string, :limit => 25, :default => "", :null => false t.column :last_name, :string, :limit => 40, :default => "", :null => false t.column :email, :string, :limit => 50, :default => "", :null => false t.column :display_name, :string, :limit => 25, :default => "", :null => false t.column :user_level, :integer, :limit => 3, :default => 0, :null => false end User.create(:username=>'test',:hashed_password=>'test',:first_name=>'test',:last_name=>'test',:email=>'[email protected]',:display_name=> 'test',:user_level=>9) end end When I run rake db:migrate the table is created with the columns as mentioned above but the test data are not there mysql>select * from users; Empty set (0.00 sec) EDIT I just dropped the whole database and restarted the migration and now it is showing the following error. rake aborted! An error has occurred, all later migrations canceled: Can't mass-assign protected attributes: username, hashed_password, first_name, last_name, email, display_name, user_level What am I doing wrong please help? Thank you.

• Pros/Cons of MySQL vs Postgresql for production Ruby on Rails environment?

  - by cakeforcerberus

  I will soon be switching from sqlite3 to either postgres or mysql. What should I consider when making this decision? Is mysql more suited for Rails than postgres in some areas and/or vice versa? Or, as I somewhat suspect, does it not really matter either way? Another factor that might play into my decision is the availability of tools to data pump my test data from the sqlite3 db to my new one. Is there anything that ActiveRecord provides natively to do this or any decent plugins/gems to help with this task? BONUS: How do I pronounce "Postgresql" and sound like I know what I'm talking about? :) Thanks Greg Smith for providing the following link that shows the most common pronunciations: http://www.postgresql.org/community/survey.33 UPDATE: Reference this question for more: http://stackoverflow.com/questions/110927/do-you-recommend-postgresql-over-mysql FYI: I ended up using MySQL. There is a neat plugin called yamldb that really saved me some time with the data transfer from my sqlite db to my new mysql one. Instructions on how to install and use it can be found here: http://accidentaltechnologist.com/ruby/change-databases-in-rails-with-yamldb/ Thanks Tom

• A few questions about a Rails model for a simple addressbook app

  - by user284194

  I have a Rails application that lists information about local services. My objectives for this model are as follows: 1. Require the name and tag_list fields. 2. Require one or more of the tollfreephone, phone, phone2, mobile, fax, email or website fields. 3. If the paddress field has a value, then encode it with the Geokit plugin. Here is my entry.rb model: class Entry < ActiveRecord::Base validates_presence_of :name, :tag_list validates_presence_of :tollfreephone or :phone or :phone2 or :mobile or :fax or :email or :website acts_as_taggable_on :tags acts_as_mappable :auto_geocode=>{:field=>:paddress, :error_message=>'Could not geocode physical address'} before_save :geocode_paddress validate :required_info def required_info unless phone or phone2 or tollfreephone or mobile or fax or email or website errors.add_to_base "Please have at least one form of contact information." end end private def geocode_paddress #if paddress_changed? geo=Geokit::Geocoders::MultiGeocoder.geocode (paddress) errors.add(:paddress, "Could not Geocode address") if ! geo.success self.lat, self.lng = geo.lat,geo.lng if geo.success #end end end Requiring name and tag_list work, but requiring one (or more) of the tollfreephone, phone, phone2, mobile, fax, email or website fields does not. As for encoding with Geokit, in order to save a record with the model I have to enter an address. Which is not the behavior I want. I would like it to not require the paddress field, but if the paddress field does have a value, it should encode the geocode. As it stands, it always tries to geocode the incoming entry. The commented out "if paddress_changed?" was not working and I could not find something like "if paddress_exists?" that would work. Help with any of these issues would be greatly appreciated. I posted three questions pertaining to my model because I'm not sure if they are preventing each other from working. Thank you for reading my questions.

• Autocomplete Error Question - Ruby on Rails

  - by bgadoci

  I have built a very simple blog application using Ruby on Rails. New to both Ruby and Rails so excuse the stupid questions. I currently have two tables that relate to this question. I have a Post table and a Tag table. Basically I set it up such that Post has_many :tags and Tag belongs_to :post. I am using AJAX to process and display the tags in the show view of the post. I installed the auto_complete plugin and I am getting an error when I enter the letters in the text_field_with_auto_complete for tag creation. My suspicion is this is because the form is a remote_form_for or something I am doing wrong in the routes.rb. Here is the error and code: Error Processing PostsController#show (for 127.0.0.1 at 2010-04-13 23:25:46) [GET] Parameters: {"tag"=>{"tag_name"=>"f"}, "id"=>"auto_complete_for_tag_tag_name"} Post Load (0.1ms) SELECT * FROM "posts" WHERE ("posts"."id" = 0) ActiveRecord::RecordNotFound (Couldn't find Post with ID=auto_complete_for_tag_tag_name): app/controllers/posts_controller.rb:22:in `show' Rendered rescues/_trace (26.0ms) Rendered rescues/_request_and_response (0.2ms) Rendering rescues/layout (not_found) remote_form_for located in /views/posts/show.html.erb <% remote_form_for [@post, Tag.new] do |f| %> <p> <%= f.label :tag_name, "Tag" %><br/> <%= text_field_with_auto_complete :tag, :tag_name, {}, {:method => :get} %> </p> <p><%= f.submit "Add Comment" %></p> <% end %> tags_controller.rb (I'll spare you all the actions but added the following here) auto_complete_for :tag, :tag_name routes.rb map.resources :posts, :has_many => :comments map.resources :posts, :has_many => :tags map.resources :tags, :collection => {:auto_complete_for_tag_tag_name => :get }

• environment change in rake task

  - by Mellon

  I am developing Rails v2.3 app with MySQL database and mysql2 gem. I faced a weird situation which is about changing the environment in rake task. (all my setting and configurations for environment and database are correct, no problem for that.) Here is my simple story : I have a rake task like following: namespace :db do task :do_something => :environment do #1. run under 'development' environment my_helper.run_under_development_env #2. change to 'custom' environment RAILS_ENV='custom' Rake::Task['db:create'] Rake::Task['db:migrate'] #3. change back to 'development' environment RAILS_ENV='development' #4. But it still run in 'customer' environment, why? my_helper.run_under_development_env end end The rake task is quite simple, what it does is: 1. Firstly, run a method from my_helper under "development" environment 2. Then, change to "custom" environment and run db:create and db:migrate until now, everything is fine, the environment did change to "custom" 3. Then, change it back again to "development" environment 4. run helper method again under "development" environment But, though I have changed the environment back to "development" in step 3, the last method still run in "custom" environment, why? and how to get rid of it? --- P.S. --- I have also checked a post with the similar situation here, and tried to use the solution there like (in step 2): ActiveRecord::Base.establish_connection('custom') Rake::Task['db:create'] Rake::Task['db:migrate'] to change the database connection instead of changing environment but, the db:create and db:migrate will still run under "development" database, though the linked post said it should run for "custom" database... weird

• unix at command pass variable to shell script?

  - by Andrew

  Hi, I'm trying to setup a simple timer that gets started from a Rails Application. This timer should wait out its duration and then start a shell script that will start up ./script/runner and complete the initial request. I need script/runner because I need access to ActiveRecord. Here's my test lines in Rails output = `at #{(Time.now + 60).strftime("%H:%M")} < #{Rails.root}/lib/parking_timer.sh STRING_VARIABLE` return render :text => output Then my parking_timer.sh looks like this #!/bin/sh ~/PATH_TO_APP/script/runner -e development ~/PATH_TO_APP/lib/ParkingTimer.rb $1 echo "All Done" Finally, ParkingTimer.rb reads the passed variable with ARGV.each do|a| puts "Argument: #{a}" end The problem is that the Unix command "at" doesn't seem to like variables and only wants to deal with filenames. I either get one of two errors depending on how I position "s If I put quotes around the right hand side like so ... "~/PATH_TO_APP/lib/parking_timer.sh STRING_VARIABLE" I get, -bash: ~/PATH_TO_APP/lib/parking_timer.sh STRING_VARIABLE: No such file or directory I I leave the quotes out, I get, at: garbled time This is all happening on a Mac OS 10.6 box running Rails 2.3 & Ruby 1.8.6 I've already messed around w/ BackgrounDrb, and decided its a total PITA. I need to be able to cancel the job at any time before it is due.

• Rails 1.0 - Using composed_of gives me a wrong number of arguments (1 for 5) error

  - by Tristan Havelick

  I am developing a Rails 1.0 application (I can't upgrade, it's a strange situation) for which I am trying to use the :composed_of functionality.

• Multiple forms on a single page

  - by normalocity

  I've got an app that's in invite-only beta right now. Problem is, I can't get the invite system to work. :( On my root page there's a login form (which works just fine), and I'm trying to add a "request invite" form on the same page. I started doing it by putting the form for InviteRequest (ActiveRecord) inside a partial, in the "views" folder for "InviteRequest". The app is definitely calling this partial, but I'm getting the following error: NoMethodError in User_sessions#new Showing app/views/invite_request/_new.html.erb where line #2 raised: undefined method `invite_requests_path' for #<ActionView::Base:0x25b3248> Extracted source (around line #2): 1: <% @invite_request = InviteRequest.new() %> 2: <% form_for @invite_request do |ir| %> 3: <%= ir.label :email %> 4: <%= ir.text_field :email %> 5: <% end %> I also read through the "Multiple Models in a Form" section of my trusty copy of "Agile Web Development with Rails", about maybe doing this with a "fieldset" tag, but not sure if this is the right approach. Thx.

• Saving a record in Authlogic table

  - by denniss

  I am using authlogic to do my authentication. The current model that serves as the authentication model is the user model. I want to add a "belongs to" relationship to user which means that I need a foreign key in the user table. Say the foreign key is called car_id in the user's model. However, for some reason, when I do u = User.find(1) u.car_id = 1 u.save! I get ActiveRecord::RecordInvalid: Validation failed: Password can't be blank My guess is that this has something to do with authlogic. I do not have validation on password on the user's model. This is the migration for the user's table. def self.up create_table :users do |t| t.string :email t.string :first_name t.string :last_name t.string :crypted_password t.string :password_salt t.string :persistence_token t.string :single_access_token t.string :perishable_token t.integer :login_count, :null => false, :default => 0 # optional, see Authlogic::Session::MagicColumns t.integer :failed_login_count, :null => false, :default => 0 # optional, see Authlogic::Session::MagicColumns t.datetime :last_request_at # optional, see Authlogic::Session::MagicColumns t.datetime :current_login_at # optional, see Authlogic::Session::MagicColumns t.datetime :last_login_at # optional, see Authlogic::Session::MagicColumns t.string :current_login_ip # optional, see Authlogic::Session::MagicColumns t.string :last_login_ip # optional, see Authlogic::Session::MagicColumns t.timestamps end end And later I added the car_id column to it. def self.up add_column :users, :user_id, :integer end Is there anyway for me to turn off this validation?

• Avoiding Duplicate Data in DB (for use with Rails)

  - by ants

  I have five tables that I am trying to get to work nicely together but may need some help. I have three main tables: accounts members and roles. With two join tables account_members and account_member_roles. The accounts and members table are joined by account_members (fk account_id and member_id) table. The other 2 tables are the problem (roles and account_member_roles). A member of an account can have more than one role and I have the account_member_roles (fk account_member_id and role_id) table joining the account_members join table and the roles table. That seems logical but can you have a relationship with a join table? What I'd like to be able to do is when creaeting an account, for instance, I would like @account.save to include the roles and update the account_member_roles table neatly ..... but through the account_members join table. I've tried ..... accept_nested_attributes_for :members, :account_member_roles in the account.rb but I get ..... ActiveRecord::HasManyThroughCantAssociateThroughHasManyReflection (Cannot modify association 'Account#account_member_roles' because the source reflection class 'AccountMemberRole' is associated to 'AccountMember' via :has_many.) upon trying to save a record. Any advice on how I should approach this? CIA -ants

• Email Collector / Implementation

  - by Tian

  I am implementing a simple RoR webpage that collect emails from visitors and store them as objects. I'm using it as a mini-project to try RoR and BDD. I can think of 3 features for Cucumber: 1. User submits a valid email address 2. User submits an existing email address 3. User submits an invalid email My question is, for scenarios 2 and 3, is it better to handle this via the controller? or as methods in a class? Perhaps something that throws errors if an instance is instantiated in sceanrio 2 or 3? Implementation is below, love to hear some code reviews in addition to answers to questions above. Thanks! MODEL: class Contact < ActiveRecord::Base attr_accessor :email end VIEW: <h1>Welcome To My Experiment</h1> <p>Find me in app/views/welcome/index.html.erb</p> <%= flash[:notice] %> <% form_for @contact, :url => {:action => "index"} do |f| %> <%= f.label :email %><br /> <%= f.text_field :email %> <%= submit_tag 'Submit' %> <% end %> CONTROLLER: class WelcomeController < ApplicationController def index @contact = Contact.new unless params[:contact].nil? @contact = Contact.create!(params[:contact]) flash[:notice] = "Thank you for your interest, please check your mailbox for confirmation" end end end

• How do I utilize REST to post GPS data from an Android device into a Ruby on Rails application?

  - by joecan

  I am a student in the process a building an Android app that can post a GPS track into a Rails application. I would like to do things the "Rails" way and take advantage of the REST. My rails application basically has 3 models at this point: users, tracks, and points. A user has_many tracks and a track has_many points. A track also has a total distance. Points have a latitude and longitude. I have successfully been able to create an empty track with: curl -i -X POST -H 'Content-Type: application/xml' -d '<track><distance>100</distance></track>' http://localhost:3000/users/1/tracks Whoo hoo! That is pretty cool. I am really impressed that rails do this. Just to see what would happen I tried the following: curl -i -X POST -H 'Content-Type: application/xml -d '<track><distance>100</distance><points><point><lat>3</lat><lng>2</lng></point></points></track>' http://localhost:3000/users/1/tracks Fail! The server spits back: Processing TracksController#create (for 127.0.0.1 at 2010-04-14 00:03:25) [POST] Parameters: {"track"={"points"={"point"={"lng"="2", "lat"="3"}}, "distance"="100"}, "user_id"="1"} User Load (0.6ms) SELECT * FROM "users" WHERE ("users"."id" = 1) ActiveRecord::AssociationTypeMismatch (Point(#-620976268) expected, got Array(#-607740138)): app/controllers/tracks_controller.rb:47:in `create' It seems my tracks_controller doesn't like or understand what it's getting from the params object in my tracks_controller.rb: def create @track = @user.tracks.build(params[:track]) My xml might be wrong, but at least Rails seems to be expecting a Point from it. Is there anyway I can fix TracksController.create so that it will be able to parse xml of a track with nested multiple points? Or is there another way I should be doing this entirely?

• Rails 3 get raw post data and write it to tmp file

  - by Andrew

  I'm working on implementing Ajax-Upload for uploading photos in my Rails 3 app. The documentation says: For IE6-8, Opera, older versions of other browsers you get the file as you normally do with regular form-base uploads. For browsers which upload file with progress bar, you will need to get the raw post data and write it to the file. So, how can I receive the raw post data in my controller and write it to a tmp file so my controller can then process it? (In my case the controller is doing some image manipulation and saving to S3.) Some additional info: As I'm configured right now the post is passing these parameters: Parameters: {"authenticity_token"=>"...", "qqfile"=>"IMG_0064.jpg"} ... and the CREATE action looks like this: def create @attachment = Attachment.new @attachment.user = current_user @attachment.file = params[:qqfile] if @attachment.save! respond_to do |format| format.js { render :text => '{"success":true}' } end end end ... but I get this error: ActiveRecord::RecordInvalid (Validation failed: File file name must be set.): app/controllers/attachments_controller.rb:7:in `create'

• Ignoring a model with all blank fields in Ruby on Rails

  - by aguynamedloren

  I am trying to create multiple items (each with a name value and a content value) in a single form. The code I have is functioning, but I cannot figure out how to ignore items that are blank. Here's the code: #item.rb class Item < ActiveRecord::Base attr_accessible :name, :content validates_presence_of :name, :content end #items_controller.rb class ItemsController < ApplicationController def new @items = Array.new(3){ Item.new } end def create @items = params[:items].values.collect{|item|Item.new(item)} if @items.each(&:save!) flash[:notice] = "Successfully created item." redirect_to root_url else render :action => 'new' end end #new.html.erb <% form_tag :action => 'create' do %> <%@items.each_with_index do |item, index| %> <% fields_for "items[#{index}]", item do |f| %> <p> Name: <%= f.text_field :name %> Content: <%= f.text_field :content %> </p> <% end %> <% end %> <%= submit_tag %> <% end %> This code works when all fields for all items are filled out in the form, but fails if any fields are left blank (due to validations). The goal is that 1 or 2 items could be saved, even if others are left blank. I'm sure there is a simple solution to this, but I've been tinkering for hours with no avail. Any help is appreciated!

• Can a standalone ruby script (windows and mac) reload and restart itself?

  - by user30997

  I have a master-workers architecture where the number of workers is growing on a weekly basis. I can no longer be expected to ssh or remote console into each machine to kill the worker, do a source control sync, and restart. I would like to be able to have the master place a message out on the network that tells each machine to sync and restart. That's where I hit a roadblock. If I were using any sane platform, I could just do: exec('ruby', __FILE__) ...and be done. However, I did the following test: p Process.pid sleep 1 exec('ruby', __FILE__) ...and on Windows, I get one ruby instance for each call to exec. None of them die until I hit ^C on the window in question. On every platform I tried this on, it is executing the new version of the file each time, which I have verified this by making simple edits to the test script while the test marched along. The reason I'm printing the pid is to double-check the behavior I'm seeing. On windows, I am getting a different pid with each execution - which I would expect, considering that I am seeing a new process in the task manager for each run. The mac is behaving correctly: the pid is the same for every system call and I have verified with dtrace that each run is trigging a call to the execve syscall. So, in short, is there a way to get a windows ruby script to restart its execution so it will be running any code - including itself - that has changed during its execution? Please note that this is not a rails application, though it does use activerecord.

• sqlalchemy relation through another (declarative)

  - by clayg

  Is anyone familiar with ActiveRecord's "has_many :through" relations for models? I'm not really a Rails guy, but that's basically what I'm trying to do. As a contrived example consider Projects, Programmers, and Assignments: from sqlalchemy import create_engine from sqlalchemy.orm import sessionmaker from sqlalchemy import Column, ForeignKey from sqlalchemy.types import Integer, String, Text from sqlalchemy.orm import relation from sqlalchemy.ext.declarative import declarative_base Base = declarative_base() class Assignment(Base): __tablename__ = 'assignment' id = Column(Integer, primary_key=True) description = Column(Text) programmer_id = Column(Integer, ForeignKey('programmer.id')) project_id = Column(Integer, ForeignKey('project.id')) def __init__(self, description=description): self.description = description def __repr__(self): return '<Assignment("%s")>' % self.description class Programmer(Base): __tablename__ = 'programmer' id = Column(Integer, primary_key=True) name = Column(String(64)) assignments = relation("Assignment", backref='programmer') def __init__(self, name=name): self.name = name def __repr__(self): return '<Programmer("%s")>' % self.name class Project(Base): __tablename__ = 'project' id = Column(Integer, primary_key=True) name = Column(String(64)) description = Column(Text) assignments = relation("Assignment", backref='project') def __init__(self, name=name, description=description): self.name = name self.description = description def __repr__(self): return '<Project("%s", "%s...")>' % (self.name, self.description[:10]) engine = create_engine('sqlite://') Base.metadata.create_all(engine) Session = sessionmaker(bind=engine) session = Session() Projects have many Assignments. Programmers have many Assignments. (understatement?) But in my office at least, Programmers also have many Projects - I'd like this relationship to be inferred through the Assignments assigned to the Programmer. I'd like the Programmer model to have a attribute "projects" which will return a list of Projects associated to the Programmer through the Assignment model. me = session.query(Programmer).filter_by(name='clay').one() projects = session.query(Project).\ join(Project.assignments).\ join(Assignment.programmer).\ filter(Programmer.id==me.id).all() How can I describe this relationship clearly and simply using the sqlalchemy declarative syntax? Thanks!

• How to validate presence of an uploaded file in rails?

  I'm playing around creating a rails file uploader and have struck a problem that should have an obvious solution. How do I check that a file has been selected in my form and uploaded? Here is my new.html.erb view <h2>Upload File</h2> <% form_for(@upload_file, :url => {:action => 'save'}, :html => {:multipart => true}) do |f| %> <%= f.error_messages %> <p> <%= f.label :file -%> <%= f.file_field :upload -%> </p> <p> <%= f.label :description %> <%= f.text_field :description %> </p> <p> <%= f.label :file_type %> <%= f.select :file_type, ["XML Data"] %> </p> <p><%= f.submit 'Upload File' %></p> <% end %> and here is my upload_file.rb model class UploadFile < ActiveRecord::Base validates_presence_of :description validates_presence_of :file_type validates_presence_of :upload def upload=(upload_file_field) self.name = "#{Time.now.strftime("%Y%m%d%H%M%S")}_#{upload_file_field.original_filename}" File.open("#{RAILS_ROOT}/public/upload/#{self.name}", "wb") { |f| f.write(upload_file_field.read) } end end If I use this as shown here, the validation validates_presence_of :upload always fails and I am returned to my form with an error message. I'd be very grateful if someone could explain how to do this validation correctly, and I'd be even more grateful if they could explain why it works. Thanks.

• Rails - handling global site settings

  - by egarcia

  I'm developing a new rails application which is supposed to be installed several times in order to implement several sites. There are some things, like the "Site Title" or the "Default Number of Items per Page" that clearly belong to a "global settings" table / config file. I've made a list of the things I think I'll need: ActiveRecord model that is capable of: Storing different kinds of data. I suppose this would be accomplished encoding the values on a string on the db, probably with a "type" field. Indexing settings by name Validations based on a "type" attribute (i.e. don't accept invalid dates on "date" settings) Validations based on a allows_nil property. A controller that allows me to change settings via views. I'm pretty sure I could implement this myself, but I'm not willing to reinvent the wheel. I've done some searching, but I could only find rails-settings, which doesn't really serve me: I need a proper model & controller so I can use declarative-authorization, and it does not provide any controller or view facilities. Is there a gem or plugin out there that implements what I want, or any library I should look at? Thanks a lot.

• Find items with belongs_to associations in Rails?

  - by dannymcc

  Hi Everyone, I have a model called Kase each "Case" is assigned to a contact person via the following code: class Kase < ActiveRecord::Base validates_presence_of :jobno has_many :notes, :order => "created_at DESC" belongs_to :company # foreign key: company_id belongs_to :person # foreign key in join table belongs_to :surveyor, :class_name => "Company", :foreign_key => "appointedsurveyor_id" belongs_to :surveyorperson, :class_name => "Person", :foreign_key => "surveyorperson_id" I was wondering if it is possible to list on the contacts page all of the kases that that person is associated with. I assume I need to use the find command within the Person model? Maybe something like the following? def index @kases = Person.Kase.find(:person_id) or am I completely misunderstanding everything again? Thanks, Danny EDIT: If I use: @kases= @person.kases I can successfully do the following: <% if @person.kases.empty? %> No Cases Found <% end %> <% if @person.kases %> This person has a case assigned to them <% end %> but how do I output the "jobref" field from the kase table for each record found?

• Routing problem with calling a new method without an ID

  - by alkaloids

  I'm trying to put together a form_tag that edits several Shift objects. I have the form built properly, and it's passing on the correct parameters. I have verified that the parameters work with updating the objects correctly in the console. However, when I click the submit button, I get the error: ActiveRecord::RecordNotFound in ShiftsController#update_individual Couldn't find Shift without an ID My route for the controller it is calling looks like this looks like this: map.resources :shifts, :collection => { :update_individual => :put } The method in ShiftsController is this: def update_individual Shift.update(params[:shifts].keys, params[:shifts].values) flash[:notice] = "Schedule saved" end The relevant form parts are these: <% form_tag( update_individual_shifts_path ) do %> ... (fields for...) <%= submit_tag "Save" %> <% end %> Why is this not working? If I browse to the url: "http://localhost:3000/shifts/update_individual/5" (or any number that corresponds to an existing shift), I get the proper error about having no parameters set, but when I pass parameters without an ID of some sort, it errors out. How do I make it stop looking for an ID at the end of the URL?

• Re-use of database object in sub-sonic

  - by cantabilesoftware

  Yet another newbie SubSonic/ActiveRecord question. Suppose I want to insert a couple of records, currently I'm doing this: using (var scope = new System.Transactions.TransactionScope()) { // Insert company company c = new company(); c.name = "ACME"; c.Save(); // Insert some options company_option o = new company_option(); o.name = "ColorScheme"; o.value = "Red"; o.company_id = c.company_id; o.Save(); o = new company_option(); o.name = "PreferredMode"; o.value = "Fast"; o.company_id = c.company_id; o.Save(); scope.Complete(); } Stepping through this code however, each of the company/company_option constructors go off and create a new myappDB object which just seems wasteful. Is this the recommended approach or should I be trying to re-use a single DB object - and if so, what's the easiest way to do this?

• Error when compiling a WinForms project that uses SubSonic library

  - by Mike Devenney

  The code generation is working but I get the following errors when I try to build the project: Error 4 Source file '...Project Path...\Structs.cs' could not be opened ('Unspecified error ') PPSGenerator Error 5 Source file '...Project Path...\Context.cs' could not be opened ('Unspecified error ') PPSGenerator Error 6 Source file '...Project Path...\ActiveRecord.cs' could not be opened ('Unspecified error ') PPSGenerator Error 7 Source file '...Project Path...\StoredProcedures.cs' could not be opened ('Unspecified error ') PPSGenerator I'm using VS2010 on a Windows 7 64 bit machine. Project is targeting Framework 3.5... any ideas? Also noticed the following warnings, but not sure that these are as important: Warning 1 The C# 2.0 and C# 3.5 compilers are no longer supported. Templates will always be compiled with the version 4 compiler instead of 'v3.5' as specified. ...ProjectPath...\Structs.tt 1 4 Warning 2 Multiple template directives were found in the template. All but the first one will be ignored. Multiple parameters to the template directive should be specified within one template directive. ...ProjectPath...\Settings.ttinclude 1 4 Warning 3 Compiling transformation: The variable 'parameters' is assigned but its value is never used ...ProjectPath...\SQLServer.ttinclude 92 15 Thanks!

• accepts_nested_attributes with Model.update for multiple models

  - by Ohad

  Hi, I'm trying to follow http://railscasts.com/episodes/198-edit-multiple-individually but I would like to save objects which are nested (accepts_nested_attributes_for). I've added the following in my controller: def edit_multiple @people = Person.find(params[:person_ids], :include => [:parameters]) end def update_multiple keys = params[:people].keys if keys.empty? flash[:error] = "Please select at least one person" redirect_to :back and return end values = keys.map {|k| params[:people][k]} @people = Person.update(keys,values).reject { |h| h.errors.empty? } if @people.empty? flash[:notice] = 'Updated people!' redirect_to person_path else redirect_to edit_multiple_path end end and in the view: <% form_tag update_multiple_people_path, :method => :post do %> <% for person in @people %> <% fields_for "people[]", host do |f| %> <%= f.error_messages :object_name => "person" %> <h3><%= h person.name %></h3> <% for parameter in person.parameters %> <% f.fields_for "person_parameters[]", parameter do |builder| -%> <%= render "common/parameters", :f => builder %> <% end -%> <% end -%> <p><%= link_to_add_fields "Add a parameter", f, :person_parameters, "common/parameters" %></p> <% end %> <% end %> <p><%= submit_tag "Edit these Parameter(s)" %></p> <% end %> but I'm always getting a mistmatch - e.g. ActiveRecord::AssociationTypeMismatch and Parameter(#70341811965140) expected, got Array(#70341874300460) Thanks!
