Rails: Why use form_for helper instead of writing html?

What are the benefits of using form_for over just writing the form html yourself?

It often seems a lot more complicated if you are using the rails helper tags to write html output.

Form helpers are especially helpful when dealing with resources, and when staying close to rails conventions. They populate a form with a resource's data, abstract away information that would otherwise be hardcoded into the markup (E.G. urls, ids, etc.), and save lots of boilerplate code.

  • form_for writes the correct method attribute based on the object used: post for create, patch for update.
  • form_for generates a hidden field to prevent forgery.
  • form_for allows to fill input values without setting it manually.
  • form_for allows to use different styles for inputs with errors without setting it manually.
