Rails: How to disable asterisk on form's required fields?

由 邮差的信 提交于 2019-11-27 05:35:31
问题 When I add the 'Required' attribute to html input fields, Rails pre-pends an asterisk (*) before the label. Does anyone know how to prevent this?

问题 How can I create an after confirmation redirect in devise? Before I added the confirmation module the custom after_sign_up_path worked fine for the first time login/signup but now when I click the confirmation link in the email it redirects to the path i set for the after login path (user profile).

问题 I'm starting a new project in Rails, and it looks like the application.js manifest file is doing something funny with the javascripts that I reference - does it cache those files as part of the asset pipeline? Here's what happened. I added a javascript file named jquery.autoresize.js to the vendor/assets/javascripts folder, and then referenced the file in the application.js manifest like this: //= require jquery.autoresize.js Then I started up the rails server. But after navigating around in

由 試著忘記壹切 提交于 2019-11-27 05:06:07
问题 I started making a Rails 3.1 engine, and I'm having a hard time testing it using rspec. First of all, if I run rails g integration_test whatever it creates a regular integration test in tests/integration instead of spec/requests (the rspec-rails gem is installed and required as a development dependency in the gemspec file) Also, when I run a spec test I get an error saying the table corresponding to the model I'm testing has not been created. I tried rake engine_name:install:migrations and

由 自闭症网瘾萝莉.ら 提交于 2019-11-27 04:22:05
问题 I have found a few articles addressing the issue of helpers within an engine not being accessible to the consuming (parent) application. To make sure we are all on the same page, let's say we have this: module MyEngine module ImportantHelper def some_important_helper ...do something important... end end end If you look at the rails engine documentation in the "Isolated engine's helpers" (L293), it says: # Sometimes you may want to isolate engine, but use helpers that are defined for it. # If
