How do I create a duplicate with associations included?
I'm fairly new to Rails and still learning. I recently stumbled upon a problem that I'm sure there is an easy way to fix it, but I haven't figured it out yet.
In the application I'm trying to create there are projects. Each project has multiple tasks. Once one project is set up with all tasks I want to use this as a template for creating new projects (with the same set of tasks). Some of the code contains snippets from episodes here on GoRails (the tasks are sortable etc). Cocoon is used for nested forms.
I have been trying to create duplicates of the template with and without deep_clonable and amoeba, but they are not picking up the associated tasks in the forms.
I'm pretty much at a stand still atm.

class Project < ApplicationRecord
belongs_to :user
has_many :tasks, inverse_of: :project, dependent: :destroy
accepts_nested_attributes_for :tasks, reject_if: :all_blank, allow_destroy: true
amoeba do
enable
prepend :title => "Copy of "
end
end(The amoeba part is not present when not in use in the controller.)
class Task < ApplicationRecord belongs_to :project, touch: true end
Try 1
from projects_conroller.rb - An online answer which seem to work for some.
def clone
@project = Project.find(params[:id])
@project = Project.new(@project.attributes)
render 'new'
endTasks show up, but throws an error on save.
Completed 401 Unauthorized in 19ms (ActiveRecord: 3.7ms) ActiveRecord::RecordNotFound (Couldn't find Task with ID=1 for Project with ID=): app/controllers/projects_controller.rb:32:in `create'
Try 2 - deep_clonable
def clone
@project = Project.find(params[:id]).deep_clone include: :tasks, except: [ { task: [:status ] } ], only: :title
render 'new'
endTasks are not showing up in form. Even when used in its simplest form with only include:
Try 3 - amoeba
Try 3 - amoeba
def clone
@project = Project.find(params[:id]).amoeba_dup
render 'new'
endTasks are not showing up in form.
I'm guessing this may be solved with a single line of code by more experienced programmers.
Any help is greatly appreciated.

Hey shesso,
At first glance, it looks like you need to add the association to your amoeba block:

amoeba do enable include_association :tasks prepend :title => "Copy of " end
With this done, re-try your 3rd attempt
Sorry. I've been adding and removing parts in the amoeba code to see if anything changes.
Added the include association back in, but the tasks still do not show up.

Oh, and on your clone method, you need to call save:
def clone @project = Project.find(params[:id]).amoeba_dup.save render 'new' end
That's probably your real issue - I just pulled up one of my projects where I used amoeba and noticed I had to call save on it. Sorry, I should have done that first =\
Adding .save creates the project and connects copies of the tasks!
but I get a new error stopping the form view being loaded

ActionView::Template::Error (undefined method `model_name' for true:TrueClass):
Error seems to be fixed by changing the code to
def clone
@project = Project.find(params[:id]).amoeba_dup
@project.save
render 'new'
endThanks for your help, Jacob!
