Rails - Paperclip - How to Check the Image Dimensions before saving
Yep! Here's a custom validation I wrote for my app, it should work verbatim in yours, just set the pixels to whatever you want. def file_dimensions dimensions = Paperclip::Geometry.from_file(file.queued_for_write[:original].path) self.width = dimensions.width self.height = dimensions.height if dimensions.width < 50 && dimensions.height < 50 errors.add(:file,'Width or height must be at least 50px')
Devise "Confirmation token is invalid" when user signs up
Using Rails 4 and Devise 3.1.0 on my web app. I wrote a Cucumber test to test user sign up; it fails when the "confirm my account" link is clicked from the e-mail. Scenario: User signs up with valid data # features/users/sign_up.feature:9 When I sign up with valid user data # features/step_definitions/user_steps.rb:87 Then I should receive an email # features/step_definitions/email_steps.rb:51 Whe
Rails: Missing host to link to! Please provide :host parameter or set default_url_options[:host]
I have been googling for about 90 minutes now and still don't have an answer to this. Where do I set default_url_options? I've already set it for config.action_mailer.default_url_options to solve this same bug elsewhere, but now I'm getting this error when trying to use a URL helper inside an RSpec spec.

Override devise registrations controller
I have added a field to the sign-up form that is based on a different model, see How do I use nested attributes with the devise model for the gory details. This part is working fine.

Rails Paperclip how to delete attachment?

The method declaration looks like this: def check_box(method, options = {}, checked_value = "1", unchecked_value = "0") Which shows that you can assign other values if you want to, but that is of course optional. Secondly, th
asset_sync gem error: rake assets:precompile fails : does not match the server certificate (OpenSSL::SSL::SSLError)
asset_sync gem error :( The first error I started out with was related to the unf gem, so I added gem "unf", "~> 0.1.3" to my gemfile and tried things again. No luck :( After more research I may have an issue with another setting related to my aws bucket. My dns is hosted via route53 and I wanted to use a custom domain to serve my assets.
