  • rake migration aborted: could not find table 'roles'

    - by user464180
    I just inherited code that I'm attempting to run the migrations for but I keep getting a rake aborted error. I've come across others that have what appears to be similar issues, but most involved Heroku and I'm trying to run this locally (to start.) I've tried troubleshooting using both PostgreSQL and SQLite, and both produce the same issue. The table "roles" referenced is the second migration called, so I'm having a hard time figuring out what is causing it to not get built. Any and all assistance is greatly appreciated. Thanks in advance. Here's the roles migration: class CreateRoles < ActiveRecord::Migration def change create_table :roles do |t| t.string :name t.timestamps end end end Here is the trace for SQLite: ** Invoke db:migrate (first_time) ** Invoke environment (first_time) ** Execute environment rake aborted!

  • Why is /usr/bin/env permission denied to rails server?

    - by Eric Hopkins
    I've just set up rails on an apache server running on Ubuntu, and when I try to go to the root page it gives this error: /usr/bin/env: bash: Permission denied env and all the directories in the path all have permissions 755. I tried setting env to have permissions 777 but still got the same error. Rails is running as "nobody". Why is this happening? I don't know what else to try.

  • How can I avoid permission denied errors when attempting to deploy a rails app with capistrano?

    - by joshee
    Total noob here. I'm attempting to deploy an app through Capistrano. I'm getting relentless permission denied errors when I attempt to run cap deploy:update. Seemingly at least some of these errors are due to missing directories that trigger a "Permission Denied" error. (I'm doing setup on root just temporarily.) set :user, 'root' set :domain, 'domainname.com' set :application, 'appname' # adjust if you are using RVM, remove if you are not $:.unshift(File.expand_path('./lib', ENV['rvm_path'])) require "rvm/capistrano" set :rvm_ruby_string, '1.9.2' # file paths set :repository, "ssh://[email protected]/~/git/appname.git" set :deploy_to, "/var/rails/appname" # distribute your applications across servers (the instructions below put them # all on the same server, defined above as 'domain', adjust as necessary) role :app, domain role :web, domain role :db, domain, :primary => true set :deploy_via, :remote_cache set :scm, 'git' set :branch, 'master' set :scm_verbose, true set :use_sudo, false set :rails_env, :production namespace :deploy do desc "cause Passenger to initiate a restart" task :restart do run "touch #{current_path}/tmp/restart.txt" end desc "reload the database with seed data" task :seed do run "cd #{current_path}; rake db:seed RAILS_ENV=#{rails_env}" end end after "deploy:update_code", :bundle_install desc "install the necessary prerequisites" task :bundle_install, :roles => :app do run "cd #{release_path} && bundle install" end Here's my result: ** [domainname.com :: out] Cloning into '/var/rails/appname/shared/cached-copy'... ** [domainname.com :: err] Permission denied, please try again. ** [domainname.com :: err] Permission denied, please try again. ** [domainname.com :: err] Permission denied (publickey,gssapi-with-mic,password). ** [domainname.com :: err] fatal: The remote end hung up unexpectedly I'm able to ssh without a password, so not sure about that publickey error.

  • dublicate display of Posts from controller - conditions and joins problem - Ruby on Rails

    - by bgadoci
    I have built a blog application using Ruby on Rails. In the application I have posts and tags. Post has_many :tags and Tag belongs_to :post. In the /views/posts/index.html view I want to display two things. First is a listing of all posts displayed 'created_at DESC' and then in the side bar I am wanting to reference my Tags table, group records, and display as a link that allows for viewing all posts with that tag. With the code below, I am able to display the tag groups and succesfully display all posts with that tag. There are two problems with it thought. /posts view, the code seems to be referencing the Tag table and displaying the post multiple times, directly correlated to how many tags that post has. (i.e. if the post has 3 tags it will display the post 3 times). /posts view, only displays posts that have Tags. If the post doesn't have a tag, no display at all. /views/posts/index.html.erb <%= render :partial => @posts %> /views/posts/_post.html.erb <% div_for post do %> <h2><%= link_to_unless_current h(post.title), post %></h2> <i>Posted <%= time_ago_in_words(post.created_at) %></i> ago <%= simple_format h truncate(post.body, :length => 300) %> <%= link_to "Read More", post %> | <%= link_to "View & Add Comments (#{post.comments.count})", post %> <hr/> <% end %> /models/post.rb class Post < ActiveRecord::Base validates_presence_of :body, :title has_many :comments, :dependent => :destroy has_many :tags, :dependent => :destroy cattr_reader :per_page @@per_page = 10 end posts_controller.rb def index @tag_counts = Tag.count(:group => :tag_name, :order => 'updated_at DESC', :limit => 10) @posts=Post.all(:joins => :tags,:conditions=>(params[:tag_name] ? { :tags => { :tag_name => params[:tag_name] }} : {} ) ).paginate :page => params[:page], :per_page => 5 respond_to do |format| format.html # index.html.erb format.xml { render :xml => @posts } format.json { render :json => @posts } format.atom end end

  • link_to passing paramater and display problem - tag feature - Ruby on Rails

    - by bgadoci
    I have gotten a great deal of help from KandadaBoggu on my last question and very very thankful for that. As we were getting buried in the comments I wanted to break this part out. I am attempting to create a tag feature on the rails blog I am developing. The relationship is Post has_many :tags and Tag belongs_to :post. Adding and deleting tags to posts are working great. In my /view/posts/index.html.erb I have a section called tags where I am successfully querying the Tags table, grouping them and displaying the count next to the tag_name (as a side note, I mistakenly called the column containing the tag name, 'tag_name' instead of just 'name' as I should have) . In addition the display of these groups are a link that is referencing the index method in the PostsController. That is where the problem is. When you navigate to /posts you get an error because there is no parameter being passed (without clicking the tag group link). I have the .empty? in there so not sure what is going wrong here. Here is the error and code: Error You have a nil object when you didn't expect it! You might have expected an instance of Array. The error occurred while evaluating nil.empty? /views/posts/index.html.erb <% @tag_counts.each do |tag_name, tag_count| %> <tr> <td><%= link_to(tag_name, posts_path(:tag_name => tag_name)) %></td> <td>(<%=tag_count%>)</td> </tr> <% end %> PostsController def index @tag_counts = Tag.count(:group => :tag_name, :order => 'updated_at DESC', :limit => 10) @posts=Post.all(:joins => :tags,:conditions=>(params[:tag_name].empty? ? {}: { :tags => { :tag_name => params[:tag_name] }} ) ) respond_to do |format| format.html # index.html.erb format.xml { render :xml => @posts } format.json { render :json => @posts } format.atom end end

  • Creating a Blog ruby on Rails - Problem Deleting Comments

    - by bgadoci
    As I always type I am new to rails and programming in general so go easy. Thanks in advance. I have successfully followed the initial tutorial from Ryan Bates on how to build a weblog in 15 minutes. If you don't know this tutorial takes you through creating posts and allowing for comments on those post. It even introduces AJAX through the creating and displaying comments on the posts show.html.erb page. All works great. Here's the hiccup, when Ryan takes you though this tutorial he clears out the comments_controller and only shows the code for creating comments. I am trying to add back the ability to edit and destroy comments. Can't see to get it to work, keeps deleting the actual post not the comment (log shows that I keep sending DELETE request to PostsController). Here is my code: class CommentsController < ApplicationController def create @post = Post.find(params[:post_id]) @comment = @post.comments.create!(params[:comment]) respond_to do |format| format.html { redirect_to @post } format.js end end def destroy @comment = Comment.find(params[:id]) @comment.destroy respond_to do |format| format.html { redirect_to(posts_url) } format.xml { head :ok } end end end /views/posts/show.html.erb <%= render :partial => @post %> <p> <%= link_to 'Edit', edit_post_path (@post) %> | <%= link_to 'Destroy', @post, :method => :delete, :confirm => "Are you sure?" %> | <%= link_to 'See All Posts', posts_path %> </p> <h2>Comments</h2> <div id="comments"> <%= render :partial => @post.comments %> </div> <% remote_form_for [@post, Comment.new] do |f| %> <p> <%= f.label :body, "New Comment" %><br/> <%= f.text_area :body %> </p> <p> <%= f.submit "Add Comment" %></p> <% end %> /views/comments/_comment.html.erb <% div_for comment do %> <p> <strong>Posted <%= time_ago_in_words(comment.created_at) %> ago </strong><br/> <%= h(comment.body) %><br/> <%= link_to 'Destroy', @comments, :method => :delete, :confirm => "Are you sure?" %> </p> <% end %>

  • uninitialized constant Active Scaffold rails 2.3.5

    Hi guy, I update my rails application 2.0.2 to 2.3.5. I use active scaffold for the administration part. I change nothing in my code but a problem is coming with the update. I have a controller 'admin/user_controller' to manage users. Here is the code of the controller: class Admin::UserController < ApplicationController layout 'admin' active_scaffold :user do |config| config.columns.exclude :content, :historique_content, :user_has_objet, :user_has_arme, :user_has_entrainement, :user_has_mission, :mp, :pvp, :user_salt, :tchat, :notoriete_by_pvp, :invitation config.list.columns = [:user_login, :user_niveau, :user_mail, :user_bloc, :user_valide, :group_id] #:user_description, :race, :group, :user_lastvisited, :user_nextaction, :user_combats_gagner, :user_combats_perdu, :user_combats_nul, :user_password, :user_salt, :user_combats, :user_experience, :user_mana, :user_vie config.create.link.page = true config.update.link.page = true config.create.columns.add :password, :password_confirmation config.update.columns.add :password, :password_confirmation config.create.columns.exclude :user_password, :user_salt config.update.columns.exclude :user_password, :user_salt config.list.sorting = {:user_login => 'ASC'} config.subform.columns = [] end end This code hasn't change with the update, but when I go in this page, I got this error: uninitialized constant Users /Users/Kiva/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:443:in `load_missing_constant' /Users/Kiva/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:80:in `const_missing' /Users/Kiva/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:92:in `const_missing' /Users/Kiva/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/inflector.rb:361:in `constantize' /Users/Kiva/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/inflector.rb:360:in `each' /Users/Kiva/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/inflector.rb:360:in `constantize' /Users/Kiva/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/core_ext/string/inflections.rb:162:in `constantize' /Users/Kiva/Documents/Projet-rpg/jeu/vendor/plugins/active_scaffold/lib/extensions/reverse_associations.rb:28:in `reverse_matches_for' /Users/Kiva/Documents/Projet-rpg/jeu/vendor/plugins/active_scaffold/lib/extensions/reverse_associations.rb:24:in `each' /Users/Kiva/Documents/Projet-rpg/jeu/vendor/plugins/active_scaffold/lib/extensions/reverse_associations.rb:24:in `reverse_matches_for' /Users/Kiva/Documents/Projet-rpg/jeu/vendor/plugins/active_scaffold/lib/extensions/reverse_associations.rb:11:in `reverse' /Users/Kiva/Documents/Projet-rpg/jeu/vendor/plugins/active_scaffold/lib/active_scaffold/data_structures/column.rb:117:in `autolink?' /Users/Kiva/Documents/Projet-rpg/jeu/vendor/plugins/active_scaffold/lib/active_scaffold.rb:107:in `links_for_associations' /Users/Kiva/Documents/Projet-rpg/jeu/vendor/plugins/active_scaffold/lib/active_scaffold/data_structures/columns.rb:62:in `each' /Users/Kiva/Documents/Projet-rpg/jeu/vendor/plugins/active_scaffold/lib/active_scaffold/data_structures/columns.rb:62:in `each' /Users/Kiva/Documents/Projet-rpg/jeu/vendor/plugins/active_scaffold/lib/active_scaffold.rb:106:in `links_for_associations' /Users/Kiva/Documents/Projet-rpg/jeu/vendor/plugins/active_scaffold/lib/active_scaffold.rb:59:in `active_scaffold' /Users/Kiva/Documents/Projet-rpg/jeu/app/controllers/admin/user_controller.rb:11 I search since 2 days but I don't find the problem, can you help me please.

    Ok so got through my last problem with the difference between Postgresql and SQLite and seems like Heroku is telling me I have another one.

  • Rails: Passing new child object placeholder (build) to parent view

    - by Meltemi
    I've got 2 classes of objects... Magician has_many Rabbits and Rabbit belongs_to Magician. When viewing a Magician (show.html) I'd like to list all the associated Rabbits and then have some blank fields with a submit button to add a new Rabbit. To do so I build a new rabbit (associated to the current magician) in the Magician's show method (below). Edit2: found way to make it work but not sure if it's the "Rails way"? see comments inline (below): If I build the rabbit in Magician's show method then when show is rendered an empty (and invalid) rabbit ends the list before the new rabbit form fields are then shown. If I build it in the view itself then everything works & renders correctly. I was led to believe that we should not be doing this type of stuff in the view...if so, what's the proper way to address this? #/app/controllers/magicians_controller.rb class MagiciansController < ApplicationController respond_to :html, :json def show @magician = Magician.find(params[:id]) @rabbit = @magician.rabbits.build # <=== build here and empty rabbit gets # included in @magician.rabbits when they're rendered... # but is NOT included in @magician.rabbits.count for some reason?!?!? respond_with(@magician) end ... end #view/magicians/show.html.haml %p %b Name: = @magician.name %h2 Rabbits = "There are #{pluralize(@magician.rabbits.count, "rabbit")}" = render @magician.rabbits, :target => @magician %h2 Add a rabbit: - @rabbit = @clown.rabbits.build -# <=== build here and everything SEEMS to work = render :partial =>"rabbits/form", :locals => { :parent => @magician, :foreign_key => :magician_id, :flash => flash } Edit1: Adding generated html from partial as per request: <p> <b>Rabbit:</b> <b>Color:</b> | <b>ID:</b> <a href="/magicians/2/rabbits" data-confirm="Sure? A bunny will die" data-method="delete" rel="nofollow">Kill Rabbit</a> </p> And I suppose you probably want to see the partial that generates this: %p %b Rabbit: = rabbit.name %b Color: = rabbit.color | %b ID: = rabbit.id = link_to("Kill Rabbit", [target, rabbit], :method => :delete, :confirm => "Sure?

    I have a form field in my Rails view like this: <%= f.text_field :date, :class => "datepicker" %> A javascript function converts all input fields of that class to a jQueryUI datepicker. $(".datepicker").datepicker({ dateFormat : "dd MM yy", buttonImageOnly : true, buttonImage : "<%= asset_path('iconDatePicker.gif') %>", showOn : "both", changeMonth : true, changeYear : true, yearRange : "c-20:c+5" }) So far so good. I can edit the record and it persists the date correctly all the way to the DB. My problem is when I want to edit the record again. When the form is pre-populated from the record it displays in 'yyyy-mm-dd' format. The javascript only formats dates which are selected in the datepicker control. Is there any way I can format the date retrieved from the database? At which stage can I do this? Thanks, Dany. Some more details following the discussion below, my form is spread across two files, a view and a partial. Here's the view: <%= form_tag("/shows/update_individual", :method => "put") do %> <% for show in @shows %> <%= fields_for "shows[]", show do |f| %> <%= render "fields", :f => f %> <% end %> <% end %> <%= submit_tag "Submit"%> <% end %> And here's the _fields partial view: <p> <%= f.label :name %> <%= f.text_field :name %> </p> <p> <%= f.date %> <%= f.label :date %> <%= f.text_field :date, :class => "datepicker" %> </p> Controller code: def edit_individual @shows = Show.find(params[:show_ids]) end

  • Rails / ActiveRecord Modeling Help

    - by JM
    I’m trying to model a relationship in ActiveRecord and I think it’s a little beyond my skill level. Here’s the background. This is a horse racing project and I’m trying to model a horses Connections over time. Connections are defined as the Horse’s Current: Owner, Trainer and Jockey. Over time, a horse’s connections can change for a lot of different reasons: The owner sells the horse in a private sale The horse is claimed (purchase in a public sale) The Trainer switches jockeys The owner switches trainers In my first attempt at modeling this, I created the following tables: Horses, Owners, Trainers, Jockeys and Connections. Essentially, the Connections table was the has-many-through join table and was structured as follows: Connections Table 1 Id Horse_id Owner_id Trainer_id Jockey_id Status_Code Status_Date Change_Code The Horse, Owner, Trainer and Jockey foreign keys are self explanatory. The status code is 1 or 0 (1 active, 0 inactive) and the status date is the date the status changed. Change_code is and integer or string value that represent the reason for the change (private sale, claim, jockey change, etc) The key benefit of this approach is that the Connection is represented as one record in the connections table. The downside is that I have to have a table for Owner (1), Trainer (2) and Jockey (3) when one table could due. In my second attempt at modeling this I created the following tables: Horses, Connections, Entities The Entities tables has the following structure Entities Table id First_name Last_name Role where Role represents if the entity is a Owner, Trainer or Jockey. Under this approach, my Connections table has the following structure Connections Table 2 id Horse_id Entity_id Role Status_Code Status_Date Change_Code 1 1 1 1 1 1/1/2010 2 1 4 2 1 1/1/2010 3 1 10 3 1 1/1/2010 This approach has the benefit of eliminating two tables, but on the other hand the Connection is now comprised of three different records as opposed to one in the first approach. What believe I’m looking for is an approach that allows me to capture the Connection in one record, but also uses an Entities table with roles instead of the Owner, Trainer and Jockey tables. I’m new to ActiveRecord and rails so any and all input would be greatly appreciated. Perhaps there are other ways that would even be better. Thanks!

  • uninitialized constant Active Scaffold rails 2.3.5

    - by Kiva
    Hi guy, I update my rails application 2.0.2 to 2.3.5. I use active scaffold for the administration part. I change nothing in my code but a problem is coming with the update. I have a controller 'admin/user_controller' to manage users. Here is the code of the controller: class Admin::UserController < ApplicationController layout 'admin' active_scaffold :user do |config| config.columns.exclude :content, :historique_content, :user_has_objet, :user_has_arme, :user_has_entrainement, :user_has_mission, :mp, :pvp, :user_salt, :tchat, :notoriete_by_pvp, :invitation config.list.columns = [:user_login, :user_niveau, :user_mail, :user_bloc, :user_valide, :group_id] #:user_description, :race, :group, :user_lastvisited, :user_nextaction, :user_combats_gagner, :user_combats_perdu, :user_combats_nul, :user_password, :user_salt, :user_combats, :user_experience, :user_mana, :user_vie config.create.link.page = true config.update.link.page = true config.create.columns.add :password, :password_confirmation config.update.columns.add :password, :password_confirmation config.create.columns.exclude :user_password, :user_salt config.update.columns.exclude :user_password, :user_salt config.list.sorting = {:user_login => 'ASC'} config.subform.columns = [] end end This code hasn't change with the update, but when I go in this page, I got this error: uninitialized constant Users /Users/Kiva/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:443:in `load_missing_constant' /Users/Kiva/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:80:in `const_missing' /Users/Kiva/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:92:in `const_missing' /Users/Kiva/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/inflector.rb:361:in `constantize' /Users/Kiva/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/inflector.rb:360:in `each' /Users/Kiva/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/inflector.rb:360:in `constantize' /Users/Kiva/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/core_ext/string/inflections.rb:162:in `constantize' /Users/Kiva/Documents/Projet-rpg/jeu/vendor/plugins/active_scaffold/lib/extensions/reverse_associations.rb:28:in `reverse_matches_for' /Users/Kiva/Documents/Projet-rpg/jeu/vendor/plugins/active_scaffold/lib/extensions/reverse_associations.rb:24:in `each' /Users/Kiva/Documents/Projet-rpg/jeu/vendor/plugins/active_scaffold/lib/extensions/reverse_associations.rb:24:in `reverse_matches_for' /Users/Kiva/Documents/Projet-rpg/jeu/vendor/plugins/active_scaffold/lib/extensions/reverse_associations.rb:11:in `reverse' /Users/Kiva/Documents/Projet-rpg/jeu/vendor/plugins/active_scaffold/lib/active_scaffold/data_structures/column.rb:117:in `autolink?' /Users/Kiva/Documents/Projet-rpg/jeu/vendor/plugins/active_scaffold/lib/active_scaffold.rb:107:in `links_for_associations' /Users/Kiva/Documents/Projet-rpg/jeu/vendor/plugins/active_scaffold/lib/active_scaffold/data_structures/columns.rb:62:in `each' /Users/Kiva/Documents/Projet-rpg/jeu/vendor/plugins/active_scaffold/lib/active_scaffold/data_structures/columns.rb:62:in `each' /Users/Kiva/Documents/Projet-rpg/jeu/vendor/plugins/active_scaffold/lib/active_scaffold.rb:106:in `links_for_associations' /Users/Kiva/Documents/Projet-rpg/jeu/vendor/plugins/active_scaffold/lib/active_scaffold.rb:59:in `active_scaffold' /Users/Kiva/Documents/Projet-rpg/jeu/app/controllers/admin/user_controller.rb:11 I search since 2 days but I don't find the problem, can you help me please.

  • Basic Ruby On Rails Linking Help

    - by dweebsonduty
    So I am beginning to work with Rails and I get some of the concepts but am stuck on an important one. Let's say I have customers which has many jobs and jobs which belongs to customers. How would I go about creating a new job for a customer? I can create a link that goes to customers/1/jobs/new and I can grab the customer ID but how do I tell it that I am creating a job for customer 1? I know this is the most basic of things but I just need a push in the right direction. This is my form so far: How do I get :customer_id to populate with the customer_id param? <h1>New job</h1> <% form_for(@job) do |f| %> <%= f.error_messages %> <p> <%= f.label :customer_id %><br /> <%= f.text_field :customer_id %> </p> <p> <%= f.label :manufacturer %><br /> <%= f.text_field :manufacturer %> </p> <p> <%= f.label :serial_number %><br /> <%= f.text_field :serial_number %> </p> <p> <%= f.label :problem %><br /> <%= f.text_area :problem %> </p> <p> <%= f.label :notes %><br /> <%= f.text_area :notes %> </p> <p> <%= f.label :status %><br /> <%= f.text_field :status %> </p> <p> <%= f.label :tech_id %><br /> <%= f.text_field :tech_id %> </p> <p> <%= f.submit 'Create' %> </p> <% end %> <%= link_to 'Back', jobs_path %>

  • Associated models in Rails?

    - by dannymcc
    Hi Everyone, In my rails application I have two models called Kases and Notes. They work in the same way comments do with blog posts, I.e. each Kase entry can have multiple notes attached to it. I have got everything working, but for some reason I cannot get the destroy link to work for the Notes. I think I am overlooking something that is different with associated models to standard models. Notes Controller class NotesController < ApplicationController # POST /notes # POST /notes.xml def create @kase = Kase.find(params[:kase_id]) @note = @kase.notes.create!(params[:note]) respond_to do |format| format.html { redirect_to @kase } format.js end end end Kase Model class Kase < ActiveRecord::Base validates_presence_of :jobno has_many :notes Note Model class Note < ActiveRecord::Base belongs_to :kase end In the Kase show view I call a partial within /notes called _notes.html.erb: Kase Show View <div id="notes"> <h2>Notes</h2> <%= render :partial => @kase.notes %> <% form_for [@kase, Note.new] do |f| %> <p> <h3>Add a new note</h3> <%= f.text_field :body %><%= f.submit "Add Note" %> </p> <% end %> </div> /notes/_note.html.erb <% div_for note do %> <div id="sub-notes"> <p> <%= h(note.body) %><br /> <span style="font-size:smaller">Created <%= time_ago_in_words(note.created_at) %> ago on <%= note.created_at %></span> </p> <%= link_to "Remove Note", kase_path(@kase), :confirm => 'Are you sure?', :method => :delete, :class => 'important' %> </div> <% end %> As you can see, I have a Remove Note destroy link, but that destroys the entire Kase the note is associated with. How do I make the destroy link remove only the note? <%= link_to "Remove Note", kase_path(@kase), :confirm => 'Are you sure?', :method => :delete, :class => 'important' %> Any help would, as always, be greatly appreciated! Thanks, Danny

  • Ruby on Rails check box not updating on form submission

    - by user284194
    I have an entries controller that allows users to add contact information the website. The user-submitted information isn't visible to users until the administrator checks a check box and submits the form. So basically my problem is that if I check the check box as an administrator while initially creating an entry (entries#new) the entry will be publicly visible as expected, but if a non-admin user creates an entry (the normal user view doesn't include the 'live' check box, only the admin one does) then that entry is stuck in limbo because the entries#edit view for some reason doesn't update the boolean check box value when logged in as an admin. entries#new view: <% form_for(@entry) do |f| %> <%= f.error_messages %> Name<br /> <%= f.text_field :name %> Mailing Address<br /> <%= f.text_field :address %> #... <%- if current_user -%> <%= f.label :live %><br /> <%= f.check_box :live %> <%- end -%> <%= f.submit 'Create' %> <% end %> entries#edit (only accessible by admin) view: <% form_for(@entry) do |f| %> <%= f.error_messages %> <%= f.label :name %><br /> <%= f.text_field :name %> Mailing Address<br /> <%= f.text_field :address %> <%= f.label :live %><br /> <%= f.check_box :live %> <%= f.submit 'Update' %> <% end %> Any ideas as to why an administrator can't update the :live check box from the edit view? I would greatly appreciate any suggestions. I'm new to rails. I can post more code if it's needed. Thanks for reading my question.

  • Stop output of image if no record - paperclip - Ruby on rails

    I have just installed paperclip into my ruby on rails blog application. Everything is working great...too great. I am trying to figure out how to tell paperclip not to output anything if there is no record in the table so that I don't have broken image links everywhere. How, and where, do I do this?

  • Ruby on Rails: jQuery datepicker - dates between validation

    - by Jazz
    I have an app that allows a user to create new projects, and the search for them later. One of the options they have when creating a project is giving them start and end dates. At the moment all the code works properly for creating and searching on the dates, but I am now wanting to restrict what dates the user can enter. I am needing for an error to flag up when the user tries to enter an end date that is before the start date. It's really more for when the user is creating the project. Here is my code so far = Application.js //= require jquery //= require jquery_ujs //= require jquery-ui //= require jquery.ui.all //= require_tree . $(function() { $("#project_start_date").datepicker({dateFormat: 'dd-mm-yy'}); }); $(function() { $("#project_end_date").datepicker({dateFormat: 'dd-mm-yy'}); }); jQuery(function(){ jQuery('#start_date_A').datepicker({dateFormat: "dd-mm-yy"}); }); jQuery(function(){ jQuery('#start_date_B').datepicker({dateFormat: "dd-mm-yy"}); }); New View: <div class="start_date" STYLE="text-align: left;"> <b>Start Date:</b> <%= f.text_field :start_date, :class => 'datepicker', :style => 'width: 80px;' %> </div> <div class="end_date" STYLE="text-align: left;"> <b>End Date:</b> <%= f.text_field :end_date, :class => 'datepicker', :style => 'width: 80px;' %> </div> Search View: Start dates between <%= text_field_tag :start_date_A, params[:start_date_A], :style => 'width: 80px;' %> - <%= text_field_tag :start_date_B, params[:start_date_B], :style => 'width: 80px;' %></br> I tried following examples online to get this to work by doing this in the application.js file: $(function() { $("#project_start_date,#project_end_date").datepicker({dateFormat: 'dd-mm-yy'}); }); jQuery(function(){ jQuery('#start_date_A,#start_date_B').datepicker({dateFormat: "dd-mm-yy"}); }); But then the script doesn't run. I am new to rails and javascript so any help at all is appreciated. Thanks in advance. UPDATE: Don't know why my question has been voted to be closed. It's quite simple: I need an error to flag up when the user tries to enter an end date that is before the start date. How can I do that??

  • Rails has-and-belongs-to-many form question

    - by swilliams
    Sorry for the semi-generic title, but I'm still pretty new at rails and couldn't think of a succinct way to put the question. I have a basic habtm model setup: a Project has many Resources and a Resource can have many Projects. I have the database and models setup properly, and can do everything I need to via the console, but I'm having trouble translating it all into the view. On the show view for the Project, I want to be able to create a Resource and automatically assign it to the current Project. Here's my basic html: <p> <b>Name:</b> <%=h @project.name %> </p> <h2>Equipment</h2> <ul> <% @project.resources.each do |r| %> <li><%=h r.name %></li> <% end %> </ul> <h2>Add A Resource</h2> <% form_for(@project) do |f| %> <%= f.error_messages %> <p> Resource Name:<br /> <%= f.text_field :resources %> </p> <p> <%= f.submit 'Create' %> </p> <% end %> Obviously, that form won't work, but I'm at a loss for what to do next. I've searched around for various examples, but haven't found one for what I'm trying to do here. One thing I've thought of was to change the form to be form_for(Resource.new) and include a hidden input of the @project.id. And then when the resource_controller handles the form, check for that id and go from there. That seems like an ugly kludge though.

  • Methodology for a Rails app

    - by Aaron Vegh
    I'm undertaking a rather large conversion from a legacy database-driven Windows app to a Rails app. Because of the large number of forms and database tables involved, I want to make sure I've got the right methodology before getting too far. My chief concern is minimizing the amount of code I have to write. There are many models that interact together, and I want to make sure I'm using them correctly. Here's a simplified set of models: class Patient < ActiveRecord::Base has_many :PatientAddresses has_many :PatientFileStatuses end class PatientAddress < ActiveRecord::Base belongs_to :Patient end class PatientFileStatus < ActiveRecord::Base belongs_to :Patient end The controller determines if there's a Patient selected; everything else is based on that. In the view, I will be needing data from each of these models. But it seems like I have to write an instance variable in my controller for every attribute that I want to use. So I start writing code like this: @patient = Patient.find(session[:patient]) @patient_addresses = @patient.PatientAddresses @patient_file_statuses = @patient.PatientFileStatuses @enrollment_received_when = @patient_file_statuses[0].EnrollmentReceivedWhen @consent_received = @patient_file_statuses[0].ConsentReceived @consent_received_when = @patient_file_statuses[0].ConsentReceivedWhen The first three lines grab the Patient model and its relations. The next three lines are examples of my providing values to the view from one of those relations. The view has a combination of text fields and select fields to show the data above. For example: <%= select("patientfilestatus", "ConsentReceived", {"val1"="val1", "val2"="val2", "Written"="Written"}, :include_blank=true )% <%= calendar_date_select_tag "patient_file_statuses[EnrollmentReceivedWhen]", @enrollment_complete_when, :popup=:force % (BTW, the select tag isn't really working; I think I have to use collection_select?) My questions are: Do I have to manually declare the value of every instance variable in the controller, or can/should I do it within the view? What is the proper technique for displaying a select tag for data that's not the primary model? When I go to save changes to this form, will I have to manually pick out the attributes for each model and save them individually? Or is there a way to name the fields such that ActiveRecord does the right thing? Thanks in advance, Aaron.
