Flash no se muestra en la misma vista en Rails

Necesito mostrar flash en la misma vista (: editar) después de actualizar con éxito un objeto. Si redirijo a otra acción, todo funciona correctamente. Pero cuando necesito quedarme en: editar, no funciona. Alguien me puede explicar cual es mi error... Gracias!

Tengo el siguiente fragmento de código en mi controlador:

 def edit @setting = Setting.find_by(slug: current_user) end def update @setting = Setting.find_by(slug: current_user) if @setting.update(settings_params) flash[:success] = I18n.t('admin.settings.edit.success') else flash[:danger] = I18n.t('admin.settings.edit.not_saved') end redirect_to edit_admin_setting_url(user: current_user) end

routes.rb :

 scope ":user/" do namespace :admin do resource :setting, only: [:edit, :update] end end

Y edit.html.erb

 <% if flash[:success].present? %> <div class="<%= classes + "alert-success" %>"> <%= icon("fas", "check") %> <%= flash[:success] %> <button type="button" class="close" data-dismiss="alert" aria-label="Close"> <span aria-hidden="true">&times;</span> </button> </div> <% end %>

También probé:

 flash.now[:success] = I18n.t('admin.settings.edit.success') render :edit

Tampoco funciona.

Ese último bit de código que muestras

 flash.now[:success] = I18n.t('admin.settings.edit.success') render :edit

debería funcionar, no estoy seguro de dónde lo colocó. Con Rails 7, turbo espera que las acciones de actualización/creación se redirijan en caso de éxito y se rendericen con un estado no válido como :unprocessable_entity ; de lo contrario, muestra un error en la consola del navegador.

También debe usar generadores de rieles para obtener un código de inicio rápido y un ejemplo de cómo funciona todo.

 bin/rails generate scaffold Sample name email bin/rails db:migrate

Esta es una forma de configurar una acción de actualización:

 # GET /:user/admin/setting/edit # # renders edit.html.erb def edit @setting = Setting.find_by(slug: current_user) end # PATCH /:user/admin/setting # # redirects to user on success # renders edit.html.erb on failure def update @setting = Setting.find_by(slug: current_user) if @setting.update(settings_params) # when setting updated flash[:success] = 'Success' # set a message to show on the next request; # we have to redirect to another url redirect_to user_url(current_user) # redirect some place else, like user profile # this means we're done with `update` action # and with current request else # when settings didn't update (validation failed) # we cannot redirect, because we'll loose our # invalid object and all validation errors # NOTE: sometimes if redirect is required # errors can be assigned to `flash` flash.now[:danger] = 'Oops' # set a message to show in this request; # we have to render a response # NOTE: this might be unnecessary, because form # will also show validation errors # render edit.html.erb template, # this means we're staying in `update` action # and in current request # NOTE: this has nothing to do with `edit` action at the top render :edit, status: :unprocessable_entity end end
