Rails4 Form with remote - handling error message - ruby-on-rails

Question

I have a simple remote form like this:
= form_for :question, :url => question_path, :remote => true, :html =>{:class => 'question-form'} do |form|
and in my controller I check if in the form the EULA is accepted:
def create
if (params[:question][:eula] != 1)
puts "ERROR!"
respond_to do |format|
return format.json {render :json => {:error_message => "FOOOO", :success => false } }
end
end
#question = Question.new(question_params)
respond_to do |format|
if #question.save
format.html { redirect_to #question, notice: 'question was successfully created.' }
format.json { render :show, status: :created, location: #question }
else
format.html { render :new }
format.json { render json: #question.errors, status: :unprocessable_entity }
end
end
end
How can I access :error_message or :success in my create.js.erb file?

Answer 1

You can do Ajax request
add id to form :id => "question-form"
= form_for :question, :url => question_path, :remote => true,
:html =>{:class => 'question-form', :id => "question-form"} do |form|
and anywhere in javascript file
$("#question-form").on("submit", function(e){
e.preventDefault();
var form = $(this);
var request = $.ajax({
method: "POST",
beforeSend: function(xhr) {xhr.setRequestHeader('X-CSRF-Token', $('meta[name="csrf-token"]').attr('content'))},
url: "/questions",
dataType: "json",
data: form.serialize()
})
request.done(function(res){
console.log(res.success);
})
request.catch(function(jqXHR){
console.log(jqXHR.responseJSON)
})
})
