Set checkbox default to true on rails

I'm trying to set the default value of a check bo开发者_开发问答x to be true by default using check_box helper in Rails. I couldn't find the solutions in the Rails api documentation

This seems to be real easy with check_box_tag, but I need to use the above helper as I require it for a model object.

Is it possible to use check_box_tag for a model object..? Doesn't look to be so from the documentation.

Could you please suggest any javascript, jquery work arounds if I can't directly implement this in Rails.

I'm on Rails 2.0.2 for project specific purposes.

Any guidance on this would be really handy..

Thank you very much..

Since the checkbox is tied to one of your model's fields, all you need to do is set the value to true on your model:

In your controller:

def new
  @model = Model.new
  @model.my_value = true
end

In your view:

<%= f.check_box :my_value %>

I made use of check_box_tag, as I was able to find an efficient workaround to suit my requirement with help..

This is how one could use the same:-

<%=check_box_tag "model[local_variable]",1,true %>

This probably shows how more versatile is check_box_tag ..
