I have a rails application in development that is taking a submitted form, sending it via a SOAP call using the SAVON gem, and is then receiving back an error message.
My question is: how do I pass that returned error message received in the model back to the controller where I can flash it?
After hours of work, incredible frustration, and questioning the very foundations of what I know, it ended up being a typo.
For those who find their way here, this is one way to pass an error from your model to your controller, which is subsequently displayed in your view:
# In your model
self.errors.add(:base, "#{error.to_s}")
# In your controller
flash.now[:error] = "#{@user.errors.full_messages.to_sentence}"
# In your view
<%= content_tag(:div, flash[:error], :id => "flash_error") if flash[:error] %>
