如何修改rails控制器中的参数

Question

Controller has to modify the session_id before saving the information.

user.rb
    has_one :room

class Room < ApplicationRecord
    belongs_to :user, optional: true
end

Rooms_controller.rb

n_room = room_params
    n_room[:room][:session_id] = session.session_id
    respond_to do |format|
      binding.pry
      if current_user.create_room(params[:n_room])
        format.html { redirect_to '/rooms/#{@new_room.id}'}

But this is not working, the session_id is not stored in the rooms row.

Question 1: How to modify 'rooms_params'? Question 2: How to pass it to rooms model in the line 'current_user.create_room'? Thank you

Answer 1

Define in this way

def create
  params[:room][:session_id] = 1
  respond_to do |format|
    if current_user.create_room(room_params)
      format.html { redirect_to '/rooms/', notice: 'Room was successfully created.' }
   else
     format.html { render :new }
   end
end

def room_params
  params.require(:room).permit(:name, :type, :session_id)
end
