Show flash message after form submit with ajax
I am creating my first app using rails and also im trying to add some ajax functionality to it. I have a registration form in my root url to create users, but I cannot find a way to show my success message after the user has been created. I can see the json response correctly, but not the flash message. Is there something missing in my code?
# Controller
def create
@user = User.new(user_params(CREATE_PARAMS))
respond_to do |format|
if @user.save
@user.send_activation_email
format.html { flash[:info] = "Success!!"
redirect_to root_url
}
format.json { render json: @user, status: :created, location: @user }
else
format.html { render "new" }
format.json { render json: @user.errors, status: :unprocessable_entity }
end
end
end
# application.html.erb
<body>
<div class="container">
<div class="message-notification">
<%= render 'shared/alert_messages' %>
</div>
<%= yield %>
</div>
</body>
# shared/_alert_messages.html.erb
<% flash.each do |message_type, message| %>
<%= content_tag(:div, message, class: "alert-message alert-message-# {message_type}") %>
<% end %>
# Handling errors users.coffee
$(document).on "ajax:error", "form#new_user", (event, data, status, xhr) ->
$("form#new_user").render_form_errors "user", data.responseJSON
$.fn.render_form_errors = (model_name, errors) ->
form = this
this.clear_form_errors()
$.each errors, (field, messages) ->
input = $('input[name="' + model_name + '[' + field + ']"]');
input.closest(".form-group").addClass("has-error")
input.parents(".form-group").append('<span class="help-block">' +
$.map(messages, (m) -> m.charAt(0).toUpperCase() +
m.slice(1)).join("<br />") + "</span>")
$.fn.clear_form_errors = () ->
this.find(".form-group").removeClass("has-error")
this.find("span.help-block").remove()
