Hi ActionView::Helpers::FormHelper methods (e.g. #text_field, #check_box...) take object_name as an argument. From this argument they infer a name that is supposed to contains the reference to the relevant object. I can''t see why the FormHelper methods were designed that way. Compared to simply passing them a reference, the current way seems too complicated and an invitation to problems

Hello, I don''t understand how formhelper works (In a Framework point of view) ... For example if I use the chek_box formhelper 1/ check_box("puppy", "gooddog", {}, "yes", "no") will call @puppy.gooddog BUT, how it is possible since the check_box has only a string parameters not instance object ? 2/ if you create your own helper which generate

Hello, I have the following: My Controller: def new . . @teammembers.each do |teammember| request = @request_thread.requests.build(:recipient_id => teammember.user_id, :full_name => ''Billy Bob T'') end My View: . . <%= f.fields_for :requests do |builder| %> <div class="field"> <%= builder.label

Hi all, After many days of struggling, I have a multi-model form with ajax elements more or less working, but I''m hitting a wall with a few bugs that I can''t figure out. Guidance would be very much appreciated. I''m using the Ryan Bates technique from Advanced Rails recipes to dynamically add and remove elements on a multi-model form.

I have a User model and an Address model. A user has_many addresses, and an address belongs_to a user. An address object for a user could be a billing, shipping or marketing address. The way I''m tracking this is via the user attributes: billing_adress_id, marketing_address_id and shipping_address_id in the user table, which holds the relevant address id. But in my form that allows a

I have the following models: class Order < ActiveRecord::Base belongs_to :billing_address belongs_to :shipping_address accepts_nested_attributes_for :billing_address accepts_nested_attributes_for :shipping_address, :reject_if => proc { |attributes| attributes[''has_shipping_address''] != ''1'' } def after_initialize self.build_billing_address

I''m trying to get a multi level nested form model working but have hit a problem. In one of my models, I have a habtm association and it''s throwing an error on a nested form and these are check boxes with a method of ''time_unit_ids[]''. The nested forms work without the habtm (time_unit_ids[]) so things are pretty much set up okay. Here''s the set up

I have a User ActiveRecord model that has email and password properties. I want to build a login for that has a "remember me" option. My view looks like this: <% @page_title = "Login" -%> <%= error_messages_for ''user'' %> <%= form_tag %> <table> <tr> <td align="right" width="1%"

Hi, I''m using the new nested forms functionality and I having problems with new created elements. I have an invoice with lines. I would like to be able to create a new invoice, in the same form insert new lines dinamically and saving the invoice and the lines when everything is validated, not before. The problem is that when I add a line dinamically to the form, the new line created

I have two models, links and tags, associated through a 3rd model, link_tags. I added the following to my link model, has_many :tags, :through => :link_tags has_many :link_tags accepts_nested_attributes_for :tags, :allow_destroy => :false, :reject_if => proc { |attrs| attrs.all? { |k, v| v.blank? } } and put this in a partial called by the new and edit forms for links,

Hey all, Chronic will parse a date range in console: Chronic.parse(1/1/2011 - 1/1/2012, :guess => false) => 2012-01-01 12:00:00 -0500..2012-01-01 12:00:01 -0500 However, when I use logger to check if it''s parsing in application, it is not: logger.info "The value of history date is #{history_date}" => The value of history date is 1/1/2011 - 1/1/2012

I''m tring to write a little function to indicate if a user is able to pay an invoice, I have my invoice model with: def canPay? if session[:user].id == self.consumer_id return true; else return false; end end as a method, but it gives the error: "undefined local variable or method `session'' for #<Invoice: 0xb7670928>" Right before

Hi, it probably is a noob question but I''m confused by this error message: active_support/dependencies.rb:478:in `const_missing'': uninitialized constant Invoice::ApplicationController Situation: I have an InvoicesController with a create method that in turn calls upon a MiddleMan.worker(:billing_worker), which in turn finds an Invoice and calls upon @invoice.print_invoice

I have a spec that''s not behaving as I''m thinking it should. Here''s the code: http://pastie.caboo.se/117931 it''s failing with: ActionView::TemplateError in ''customers/new should receive fields_for'' Mock ''ActionView::Base'' expected :form_for with ("address", #<Address id: nil, address1: "123 Main St.",

I''ve tried this (in a new method/template -- so @type doesn''t actually exist yet): check_box ''type'', ''notify_on_create'', {:checked=>''true''} But :checked seems to get swallowed. I''ve also tried setting notify_on_create to true in the Type model, but that doesn''t work either. Any way to get the

Hey all, I get error like this: ActionView::TemplateError (`@content_for_details_view_builder__-626960428'' is not allowed as an instance variable name) in app/views/shared/_details_view.haml: searchlogic (2.4.27) lib/searchlogic/rails_helpers.rb:75:in `fields_for'' searchlogic (2.4.27) lib/searchlogic/rails_helpers.rb:64:in `form_for''

I had posted earlier about ''silent failure of a controller'', what seemed to be an intractable problem where I was getting failure of a particular action in a controller while others worked. What was irritating was that there were no useful messages. Nothing to the browser, nothing in logs, and even the breakpoints wouldn''t hit. Finally by a process of elemination I found

Hi, Is it possible to use the ActionView::Helpers::FormHelper.text_field with an instance variable instead of a model. e.g. In the controller: def meth @value = ''hi there'' end In view: <%= text_field ''value'', nil %> It doesn''t work with what is above (doesn''t like the nil) and produces very strange results replacing nil with

In console, I run the following and any? returns true: drivers = Driver.select("drivers.*, drivers.id").joins([:reports, :driving_habits]).where("extract(MONTH FROM reports.time) = ? AND extract(YEAR FROM reports.time) = ?", 3, 2013).uniq.order("drivers.id asc").page(2).per(1) drivers.any? => true This correctly evaluates to true because the relation contains one
