创建新记录时如何传递current_user？

Question

I need to pass current_user for user_id when creating entity . Its not working the way i'm doing it.

def create
    @entity = Entity.new(entity_params, :user_id = current_user)
    ...
end

In Schema I have :user_id as integer for Entity table. I also have belongs_to :user association in models/entity.rb

Answer 1

new accepts a parameters hash, so it should work with:

@entity = Entity.new(entity_params.merge(user: current_user))

Another way would be

@entity = Entity.new(entity_params).tap do |entity|
  entity.user = current_user
end

Answer 2

A better way:

#app/controllers/entities_controller.rb
class EntitiesController < ApplicationController
   def create
     @entity = current_user.entities.new entity_params
     @entity.save
   end
end

Answer 3

You can also try:

def create
  @entity = current_user.entities.create(entity_params)
end
