[Rails] Problème après rechargement de formulaire avec autocomplétion en cas d'erreur

[Sephi-Chan]

En gros :

class MessagesController < ApplicationController

  def new

    @message = Message.new

  end

  

  def create

    receiver_name     = params.delete(:receiver_name)

    @message          = Message.new(params[:message])

    @message.receiver = User.find_by_name(receiver_name)

    

    if @message.save

      redirect_to @message

    else

      render :new

    end

  end

end

Et la vue :

= form_for @message do |f|

  %p

    = label_tag :receiver_name

    = text_field_tag :receiver_name, f.object.receiver.try(:name)

    = errors_for(f.object, :receiver_name)

    

  %p

    = f.label :content

    = f.text_area :content

    = errors_for(f.object, :content)

    

  %p

    = f.submit

En fait je vire l'archive, ces fragments suffisent.
