Skip to EDIT2 which works
- Project (has_many :group_permissions)
- GroupPermission (belongs_to :project)
I have a form where you can create a new project. A project has several attributes like name, status etc. and now important: iit. iit is selectable with radio buttons: yes or no.
What I want:
If someone selects yes on iit in the Project form, there should be a new record in GroupPermission. So in EVERY project where iit= 1 there should be a certain GroupPermisson.
Can I make / check this in the GroupPermission model? Like if
class GroupPermission < ActiveRecord::Base if Project.where(iit: 1) make me a record for each project end
Can I even make database entries in the model like so?
Is this the right way?
In the Project controller I added:
if params[:iit] = 1 record = GroupPermission.new(cn: 'ccc-ml', project_id: params[:id]) record.save end
It then adds a new record in GroupPermissions. But I need the :id of the project. How can I access the id of the project which is about to be saved?
In the Project Controller
after_filter :iit_test, :only => [:create] ... private def iit_test if @trial.iit == 1 record = GroupPermission.new(cn: 'ccc-ml', project_id: @project.id, name: 'CATEGORY_3') record.save end
EDIT2 works fine. I just have to check it with update etc.
Thank you in advance.
EDIT2 will only work for apis hitting the controller and not when you add a project via rails console, use in tests etc.
:iit_test will not correctly work for
update action as you are creating a new GroupPermission everytime. (GroupPermission may already exists for this project)
You should probably add a callback
after_save in the project model and handle adding of a new GroupPermission there.
