Possible to find if attribute is a required attribute?

Currently i have the following and am faced with pasting this to all
forms… yawn

Name
<%= f.text_field :name %>
Description
<%= f.text_area :description%>

If i could find out if the attribute is required then i could create a
form builder and DRy it all up.

eg in test.rb

def required_text
if self.attribute.required_field
return ‘required’
end
‘optional’
end

then in a form builder have

<label etc....

Hi Adam,

I’m not sure what what the nicest solution is, but this line would
tell you if the model allows the field to be null or not:

Model.columns_hash['column_name'].null

If that returns false, then that field cannot be null

So maybe make a helper based on that?

Hope that helps in some way

I’m not sure about getting AR to tell you the required fields, but at
the very least you should be able to wrap those up into a helper to save
the copy and pasting. Or even roll them into a custom form builder,
perhaps.
