ruby on rails - Dont recieve any messages from methods

Question

I dont recieve any messages from controller. Method works, but without showing messages.

def create
      @post = Post.new(post_params)
      @post.user_id = current_user.id if user_signed_in?
        if @post.save
          redirect_to current_user, flash: {success: "Post was created"}
        else
          render :new, flash: {alert: "Some errors"}
        end
  end

And it doesnt matter will it be a happypass or not

Answer 1

To use flash messages in controller when redirecting you need to use:

flash.alert = "Some errors"

or

flash[:alert] = "Some errors"

if you want render:

flash.now[:notice] = "Some errors"
render :new

But remember, use flash.now when rendering and flash when redirecting
