Thank you guys.

Posted in GoRails Markdown and Preview

Hey Chris,

Just wondering what are you using to preview Markdown in forum posts? I watched the whole Forum series and I saw the other video about html-pipeline gem but you don't mention syntax highlight nor Markdown preview.

Thanks in advance.

Posted in Pundit Policy and has_many through Pt. II

Hey there,

I decided to start another post although I read this one already https://gorails.com/forum/pundit-scope-and-has_many-through but I need to confirm that my query is on point.

Here's my three models:

class Project < ActiveRecord::Base
  has_many :collaborations
  has_many :users, through: :collaborations
end
class Collaboration < ActiveRecord::Base
  belongs_to :project
  belongs_to :user
end
class User < ActiveRecord::Base
 has_many :collaborations
 has_many :projects, through: :collaborations
end

What I need is to allow project.user (in this case the project creator) OR project.collaborators to see their list of projects. What I'm looking is for a way to improve this query: scope.joins(:users).where('collaborations.user_id = ? OR projects.user_id = ?', user, user)

  class Scope < Scope
    def resolve
      return scope.all if user.has_role?(:admin) && user.present?
      scope.joins(:users).where('collaborations.user_id = ? OR projects.user_id = ?', user, user)
    end
  end
  def add_member_to_project
    @project = Project.friendly.find(params[:project_id])

    if @project.update_attributes(project_params)
      user_ids = params[:project][:user_ids]

      user_ids.map do |user_id|
        @project.collaborations.build(user_id: user_id)
      end

      flash[:notice] = "Member added."
      redirect_to @project
    else
      flash[:danger] = "Member couldn't be added"
      render 'show'
    end
  end
<%= form_for @project, :url => add_member_to_project_path  do |f| %>
  <%= f.collection_check_boxes(:user_ids, @members, :id, :name) %>
  <%= f.submit "Save changes", class: "btn btn-primary" %>
<% end %>  

Thank you!

Beautiful Chris! The `presence` method trick was really nice too. Thanks for this amazing contribution.
