nested-forms

This is basically a nested form question, albeit with only one field that belongs to a parent model. My data entry form collects data for a model - however I also need to collect one other a data element/value (UserID) that actually goes into a parent record that will be created with the detail record. AFAIK Rails expects each form field to map to a model and I need to create an unbound data input field that I will use separately. How can I override this default behaviour and create a'free form/unbound field'? TIA, BC Heres something from my own app: Access it by: params[:company] and params[

I have just jumped into has_many :through association. I'm trying to implement the ability to save data for all 3 tables ( Physician , Patient and association table) through a single form. My migrations: class CreatePhysicians < ActiveRecord::Migration def self.up create_table :physicians do |t| t.string :name t.timestamps end end end class CreatePatients < ActiveRecord::Migration def self.up create_table :patients do |t| t.string :name t.timestamps end end end class CreateAppointments < ActiveRecord::Migration def self.up create_table :appointments do |t| t.integer :physician_id t.integer

I have a Project model which accepts nested attributes for Task. class Project < ActiveRecord::Base has_many :tasks accepts_nested_attributes_for :tasks, :allow_destroy => :true end class Task < ActiveRecord::Base validates_uniqueness_of :name end Uniqueness validation in Task model gives problem while updating Project. In edit of project i delete a task T1 and then add a new task with same name T1, uniqueness validation restricts the saving of Project. params hash look something like task_attributes => { {"id" => "1","name" => "T1", "_destroy" => "1"},{"name" => "T1"}} Validation on task is

I'm trying to solve a pretty common (as I thought) task. There're three models: class Product < ActiveRecord::Base validates :name, presence: true has_many :categorizations has_many :categories, :through => :categorizations accepts_nested_attributes_for :categorizations end class Categorization < ActiveRecord::Base belongs_to :product belongs_to :category validates :description, presence: true # note the additional field here end class Category < ActiveRecord::Base validates :name, presence: true end My problems begin when it comes to Product new/edit form. When creating a product I need to
