Question

I have a CustomInput < SimpleForm::Inputs::Base that I would like to avoid rendering if the attribute value is blank. IOW, I want to avoid rendering all the wrappers and components. Can I do this within the control to avoid writing if model.attribute.blank? for each control in my template?

Answer 1

Just subclass the FormBuilder and override the input method

class MyFormBuilder < SimpleForm::FormBuilder

  def input(attribute_name, options = {}, &block)
    if @template.my_action_show?
      return if @object.send(attribute_name).blank?
    end 
    super
  end

my_action_show? is just custom ApplicationHelper method that checks if

params[:action]=='show'
