Form not showing error messages (Rails 3 project)

Question

My submit form is not showing error messages...when I fill it out incorrectly and submit, it just refreshes. It should show error messages - see attached code -- but for some reason it isn't. Not sure why this is happening.

Any advice would be much appreciated!

Thanks,

Faisal

Answer 1

As your form show all errors, there might be another problem prevent saving models. Make sure you can save models in rails console.

Answer 2

Are you using Devise or another authentication library.

You might need to put an authenticity token in your forms (although that would log you out rather just redirect, but it might be the behavior if you don't have an auth library)

You should also use form_for @post so that your inputs get named correctly for your new function (that would put in the auth token for you).

You problem might also be in your model, you might have to whitelist the attributes sent by your form.
