curl script for create new flashcard not working

[nriser]

When I run the curl script for creating a new flashcard, I get a '422 Unprocessable Entity' error in rails server. I signed up and signed in with curl and passed in the token into my curl command for create, but it tells me the error, '{"user":["must exist"]}'.

{"user":["must exist"]}

flashcard controller snippet:

class FlashcardsController < ApplicationController
  before_action :set_flashcard, only: [:show, :update, :destroy]

...

  # POST /flashcards
  def create
    @flashcard = Flashcard.new(flashcard_params)

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

...

  private
    # Use callbacks to share common setup or constraints between actions.
    def set_flashcard
      @flashcard = Flashcard.find(params[:id])
    end

    # Only allow a trusted parameter "white list" through.
    def flashcard_params
      params.require(:flashcard).permit(:word, :definition)
    end
end

flashcard model

class Flashcard < ApplicationRecord
  belongs_to :user

  validates :word, presence: true
  validates :definition, presence: true
end

{"user":["must exist"]} message makes me the the database (schema) has a rule that a user_id must be present to create a new Flashcard. Are you passing a user_id when you create it? Add a binding.pry and test out the params to find out.

  def create
    binding.pry # what is params?  what is flashcard_params?
    @flashcard = Flashcard.new(flashcard_params)

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

Also, the next issue you are going to have is related to this https://github.com/ga-wdi-boston/full-stack-project/issues/814. Read that issue. You will want to consider changing your Controller to inherit from OpenReadController or ProtectedController not ApplicationController so you can access current_user.

@MicFin Thank you for your reply. binding.pry was useful. I followed the example in https://github.com/ga-wdi-boston/full-stack-project/issues/814 and now the curl script for create works.
