Rails simple form checkbox default to true

Question

How do I make a simple for boolean checkbox default to true?

assign_client is a boolean field.

I tried these:

<%= f.input :assign_client, :label => 'Charge Client?', :true %>
<%= f.input :assign_client, :label => 'Charge Client?', :value => :true %>
<%= f.input :assign_client, :label => 'Charge Client?', :value => 1 %>

Thanks for the help!

Answer 1

I think you should add input_html:

<%= f.input :assign_client, :label => 'Charge Client?', :input_html => { :checked => true }

proof

Answer 2

Your second one will work fine just remove the : so it's a boolean value rather than a symbol.

<%= f.input :assign_client, :label => 'Charge Client?', :value => true %>
