Question

I have two models

class Project < ActiveRecord::Base

  attr_accessible :created_at, :name, :status, :company_id
  has_many :phases, :dependent => :destroy

end


class Phase < ActiveRecord::Base

  attr_accessible :created_at, :date_due, :name, :project_id, :status
  belongs_to :project

end

When a new phase is created, I would like to forward the user to the show project page for the project that the new phase belongs to.

I’ve tried this, as well as a few variations, but am not quite sure of the best way to write it:

def create
    @phase = Phase.new(params[:phase])

    respond_to do |format|
      if @phase.save
        redirect_to @phase.project
      else
        format.html { render action: "new" }
        format.json { render json: @phase.errors, status: :unprocessable_entity }
      end
    end
  end

Thanks!

Updated Controller – now working. Needed to remove the respond_to block (could probably just include the different format options around the redirect, as well)

  def create
    @phase = Phase.new(params[:phase])

    if @phase.save
      redirect_to project_url(@phase.project)
    else
      render action: "new"
    end

  end

Answer 1

Try the following:

redirect_to project_path(@phase.project)

Note: This will only work if you have your routes set up correctly.

See the Using redirect_to section in Rails Guides for more information.

Edit:

The problem is probably that we aren’t passing an id to project_path(:id).

redirect_to project_path(@phase.project.id)
