Question

I have an app where the user can build a project which will have up to 12 volunteer time slots where other users can sign up to work on the project.

When a project is created, the user is asked for the default (beginning) time. This default time (Project_Times model) should be written to the begin_time in the Projects table.its own table in the database, using the project_id parameter to identify which project it belongs to.

The user can then add up to 11 more time slots if they want/need to after the @project is created.

I am having a hard time getting the project to create the default time. This is what I have:

++ Projtime (projtime.rb) Model ++

class Projtime < ActiveRecord::Base
  attr_accessible :start_time, ...
  belongs_to :project
  default_scope :order => 'times.amount ASC'
end

++ Project (project.rb) Model ++

class Project < ActiveRecord::Base
  attr_accessible :title
  belongs_to :user
  has_one :project_category
  has_many :projtimes, :dependent => :destroy
    accepts_nested_attributes_for :projtimes

  def projtimes
    Projtimes.where('project_id=?', id)
  end
end

++ Projects Controller ++

class ProjectsController < ApplicationController
  ...
  def create
    @user = current_user
    @project = current_user.build_project(params[:project])
    @project.save
    @render 'edit'
  end

where the project is automatically assigned to the user using the syntax above. I have tried to copy the same concept (factoring in the fact that there are multiple times for each project) and come up with this for the ProjtimesController:

class ProjtimesController < ApplicationController
  ...
  def create
    @project.projtimes.build
  end
end

However, I’m getting a NameError in ProjectsController#new

with uninitialized constant Project::Projtimes

I would think that with setting the belongs_to and has_many associations, this should work.

Help anyone?

Answer 1

projtime.rb should start with class Projtime not class Projime.

A second set of eyes 🙂
