  • Error when rendering a partial (RoR) passing the form as a local variable

    - by Dmitriy Likhten
    In my main template I have the following: <%= render :partial => "delivery_date", :collection => @brand.delivery_dates, :locals => {:form => f} %> However when the partial tries to use the form local variable, I get this error Showing app/views/brands/_delivery_date.html.erb where line #2 raised: wrong number of arguments (0 for 1) Extracted source (around line #2): 1: <%= delivery_date.id %> 2: <%= form.text_field :name %> 3: <% new_or_existing = delivery_date.new_record? ? 'new' : 'existing' %> 4: <% prefix = "brand[#{new_or_existing}_delivery_date_attributes][]" %> 5: <% fields_for prefix, delivery_date do |dd_f| %> Does anyone understand what this error means? Actually I want to do <% form.fields_for delivery_date do |dd_f| %> but that fails as well.

  • Store request.headers in a serialized model attribute

    - by Horace Loeb
    Here's my model: class Comment < ActiveRecord::Base serialize :request_headers end But when I try to do @comment.request_headers = request.headers I get a TypeError (can't dump anonymous class Class) exception. Another way to ask my question: how can I convert request.headers into a Hash? It uses a Hash under the covers so this should be easy, no?

  • Rails routes looking for show action

    - by user1334345
    I am pretty new to rails and basically I want to make a user registration form. I am currently using rails 3.2.3 Basically I want to make basic routes like user/register on top of basic REST route for user. Here are my routes.rb resources :user do collection do get 'register' end end And here are my rake routes: register_user_index GET /user/register(.:format) user#register user_index GET /user(.:format) user#index POST /user(.:format) user#create new_user GET /user/new(.:format) user#new edit_user GET /user/:id/edit(.:format) user#edit user GET /user/:id(.:format) user#show PUT /user/:id(.:format) user#update DELETE /user/:id(.:format) user#destroy From my understanding, since register user is on top of show, it should match with register first before going to show. However, when I try to do localhost:3000/user/register, it gives me this error: No route matches {:action="show", :controller="user"} Can somebody help me with this? Thanks!!

  • Mixing has_one and has_and_belongs_to_many associations

    - by Thomas
    I'm trying to build a database of urls(links). I have a Category model that has and belongs to many Links. Here's the migration I ran: class CreateLinksCategories < ActiveRecord::Migration def self.up create_table :links_categories, :id => false do |t| t.references :link t.references :category end end def self.down drop_table :links_categories end end Here's the Link model: class Link < ActiveRecord::Base validates :path, :presence => true, :format => { :with => /^(#{URI::regexp(%w(http https))})$|^$/ } validates :name, :presence => true has_one :category end Here's the category model: class Category < ActiveRecord::Base has_and_belongs_to_many :links end And here's the error the console kicked back when I tried to associate the first link with the first category: >>link = Link.first => #<Link id: 1, path: "http://www.yahoo.com", created_at: "2011-01-10... >>category = Category.first => #<category id : 1, name: "News Site", created_at: "2011-01-11... >>link.category << category => ActiveRecord::StatementInvalid: SQLite3::Exception: no such column : categories.link_id: Are my associations wrong or am I missing something in the database? I expected it to find the links_categories table. Any help is appreciated.

  • Database schema to store AND, OR relation, association

    - by user455387
    Many thanks for your help on this. In order for an entreprise to get a call for tender it must meet certain requirements. For the first example the enterprise must have a minimal class 4, and have qualification 2 in sector 5. Minimal class is always one number. Qualification can be anything (single, or multiple using AND, OR logical operators) I have created tables in order to map each number to it's given name. Now I need to store requirements in the database. minimal class 4 Sector Qualification 5.2 minimal class 2 Sector Qualifications 3.9 and 3.10 minimal class 3 Sector Qualifications 6.1 or 6.3 minimal class 1 Sector Qualifications (3.1 and 3.2) or 5.6 class Domain < ActiveRecord::Base has_many :domain_classes has_many :domain_sectors has_many :sector_qualifications, :through => :domain_sectors end class DomainClass < ActiveRecord::Base belongs_to :domain end class DomainSector < ActiveRecord::Base belongs_to :domain has_many :sector_qualifications end class SectorQualification < ActiveRecord::Base belongs_to :domain_sector end create_table "domains", :force => true do |t| t.string "name" end create_table "domain_classes", :force => true do |t| t.integer "number" t.integer "domain_id" end create_table "domain_sectors", :force => true do |t| t.string "name" t.integer "number" t.integer "domain_id" end create_table "sector_qualifications", :force => true do |t| t.string "name" t.integer "number" t.integer "domain_sector_id" end

  • How do I add values in an array when there is a null entry?

    - by Angela
    I want to create a real time-series array. Currently, I am using the statistics gem to pull out values for each 'day': define_statistic :sent_count, :count => :all, :group => 'DATE(date_sent)', :filter_on => {:email_id => 'email_id > = ?'}, :order => 'DATE(date_sent) ASC' What this does is create an array where there are values for a date, for example [["12-20-2010",1], ["12-24-2010",3]] But I need it to fill in the null values, so it looks more like: [["12-20-2010",1], ["12-21-2010",0], ["12-22-2010",0], ["12-23-2010",0], ["12-24-2010",3]] Notice how the second example has "0" values for the days that were missing from the first array.

  • Rails / omitted from link_to?

    - by dannymcc
    Hi Everyone, I am using a Gem to communicate with FreeagentCentral via their API. I have the following code to display a link to the relevant freeagent project: <%= link_to "#{image_tag('/images/icons/Spinning Beach Ball.png')} Freeagent Project", "#{Freeagent::Base.site.to_s + Freeagent::Project.element_path(@kase.freeagent_id).gsub(/\A\//, '').gsub!(/.xml/,'')}" if @kase.freeagent_id %> The problem - There is a / omitted from the URL which makes the url like this: https://XXXXX.freeagentcentral.comprojects/12345 where it should be: https://XXXXX.freeagentcentral.com/projects/12345 This may be simple, but to me - it's driving me crazy! Thanks, Danny

  • DataMapper save fails but with no errors

    - by Justin Bozonier
    When I try to modify and then save a model using DataMapper I get a SaveFailure exception but no errors. Specifically I see this message: "MonthlyBill#save returned false, MonthlyBill was not saved" This is the code doing the saving: post '/monthly_bills' do with_authenticated_user do |user| description = params[:description] expected_amount = params[:expected_amount] pay_period = params[:pay_period] monthly_bill = MonthlyBill.new(:description=>description, :expected_amount=>expected_amount, :pay_period=>pay_period) user.MonthlyBills << monthly_bill user.save end The User model: class User include DataMapper::Resource property :id, Serial property :email_address, String property :password, String has n, :MonthlyBills has 1, :CurrentPayPeriod end The MonthlyBill model: class MonthlyBill include DataMapper::Resource property :id, Serial property :description, String property :expected_amount,Decimal property :pay_period, Integer belongs_to :user end What is the issue and, more importantly, how can I get DataMapper to tell me more specifically what is wrong?

  • Conditional root_url (index)

    - by vise
    I'd like my application to display different data on the frontpage depending on whether the user has been logged in or not. def index if current_user # render another controllers action else # render another controllers action end end I can achieve this by using render_component. However it has been obsolete for some time. Although I can still use it as a plugin, I'm interested if anyone has a better approach. Just take in mind that rendering another controller's view directly is not an option. Thanks.

  • Rails: creating a model in the new action

    - by Joseph Silvashy
    I have an interesting situation, well it's probably not that unique at all, but I'm not totally sure how to tackle it. I have a model, in this case a recipe and the user navigates to the new path /recipes/new however the situation is that I need to be able to have the user upload images and make associations to that model in the new action, but the model doesn't have an ID yet. So I assume I need to rethink my controller, but I don't want to have redirects and whatnot, how can accomplish this? Here is the basic controller, barebones obviously: ... def new # I should be creating the model first, so it has an ID @recipe = Recipe.new end def create @recipe = Recipe.new(params[:recipe]) if @recipe.save redirect_to @recipe else render 'new' end end ... update Perhaps I can have a column thats like state which could have values like new/incomplete/complete or what-have-you. I'm mostly trying to figure out what would also be most efficient for the DB. It would be nice if I could still have a url that said '/new', instead of it be the edit path with the id, for usability sake, but I'm not sure this can be simply accomplished in the new action of my controller. Thoughts?

  • Rails3 Redirect for javascript/ajax

    - by Tiago
    Hi, I'm using a form with the remote => true. I have a validation that is working correctly. My problem is when the user enters all the correct information and writes the data at this time I do a redirect to the page of the show. Instead of redirecting, it displays the html of the show in my div. How can I make a javascript redirect that will understand? I did not want to use the window.location. Thanks...

  • how do I block my rails app from being hit by bots?

    - by codeman73
    I'm not even sure I'm using the right terminology, whether this is actually bots or not. I didn't want to use the word 'spam' because it's not like I have comments or posts that are being created/spammed. It looks more like something is making the same repeated request to my domain, which is what made me think it was some kind of bot. I've opened my first rails app to the 'public', which is a really a small group of users, <50 currently. That was last Friday. I started having performance issues today, so I looked at the log and I see tons of these RoutingErrors ActionController::RoutingError (No route matches "/portalApp/APF/pages/business/util/whichServer.jsp" with {:method=>:get}): They are filling up the log and I'm assuming this is causing the slowdown. Note the .jsp on the end and this is a rails app, so I've got no urls remotely like this in my app. I mean, the /portalApp I don't even have, so I don't know where this is coming from. This is hosted at Dreamhost and I chatted with one of their support people, and he suggested a couple sites that detail using htaccess to block things. But that looks like you need to know the IP or domain that the requests are coming from, which I don't. How can I block this? How can I find the IP or domain from the request? Any other suggestions?

It seems there is a problem while deleting the records active record is not able to find out the proper path because of multiple joins within the tables.
