How to get current_user in Rails 5 API with Devise

I have an Angular 2 app that is using a Rails 5 API to create projects (think posts). I'm trying to add the current_user id to a new project (see the attempt in the Projects controller) when created but I get NoMethodError (undefined method projects' for nil:NilClass): app/controllers/projects_controller.rb:18:increate'. Line 18 is the line that attempts to use current_user when creating the project. If I remove current user and make it Project.new or if I hard code the user_is on the client side, there are no issues but with many users, this would be a problem. In the end, I want to know how to get the current user id and insert it when creating the project.

Application Controller

class ApplicationController < ActionController::API
  include DeviseTokenAuth::Concerns::SetUserByToken

  def current_user
    @current_user
  end

end

Projects Controller

def create
  @project = current_user.projects.new(project_params)

  if @project.save
    render :show, status: :created, location: @project
  else
    render json: @project.errors, status: :unprocessable_entity
  end
end

Resolved. Issue was than angular2-token wasn't passing correct headers for subsequent requests to non-auth routes such as my projects routes. current_user is good to go now.

Looks like you haven't called the authenticate_user! method that sets the current_user.

Perhaps try making your ApplicationController look something like this...

class ApplicationController < ActionController::API
  include DeviseTokenAuth::Concerns::SetUserByToken

  before_action :authenticate_user!
end

The before_action call here ensures that the current_user method returns a value.
