While implementing the comment function Now it's jammed.

"=> {" content_id "=>" 468 "," comment "=>" Ah "},

why? And looking at the parameters, the values are being sent. .. .. Next, check the destination controller.

def comment_params
  params.require(:comment).permit(:comment, :content_id)

permit is fine. Hmm? There is no key to be in pramas.require, right?

This → "" => {"content_id" => "468", "comment" => "Ah"},

Actually, I got stuck in the same place before and forgot to make the same mistake.

The answer is simple, just instantiate with the controller on the current page I'm a big fool (laughs)

This time I was working on the show page of the timeline function, so


  def show
    @content = Content.find(params[:id])
    @user = User.find(@content.user_id)
    @comment = Comment.new #I added this.

Add the above and try again!

"comment" => {"content_id" => "468", "comment" => "Ah"},

I got a parameter key! !!


Don't forget to create an instance on the current page even after creating a new model! that's all.

Thank you very much.
