Required fields(show * before the label) is not the default about simple_form HOT 5 CLOSED

SimpleForm uses the validators API to see if the attribute is required or not, you just need to add a presence validation tor your model.
There is also a config which lets you define if all fields are required by default or not, that is used only if the model does not have validations included (which, btw, is true by default): http://github.com/plataformatec/simple_form/blob/master/lib/generators/simple_form/templates/simple_form.rb#L33

Does this depend on Rails version you are using?
On Rails 2.3 you need to install "validations_reflection" plugin in order to get "*" marks prepended automatically on attribute's label which is required (validates_presence_of :attribute).
On Rails 3 you only have to set required in the model - :presence => true
Correct me if I am mistaken.

Yup, the validators API exists only in Rails 3.
SimpleForm for Rails 2.x does not rely on validations_reflection plugin, which means it does not reflect the validations from your model to your forms. By default all attributes will be required unless you say no.

Thanks to all repliers. I am using rails 3 and it works as tundrax say. However I disagree with Carlos because if I do not use validators all attributes on the form come without the start(*). So I believe the default is "not required". This is not a big issue for me because now I use the validators and love the way it works.

Yes you're right, I meant to say that in SimpleForm for Rails 2.x, all attributes are considered required unless you say they are not. SimpleForm for Rails 3 relies on the validators, so if no validator exist for an attribute, it's not required. It'll just consider all attributes required in a form, if that form has an object that doesn't have the validators.
I'm closing this issue so.
