Ruby on Rails check_box始终呈现选中状态

Question

my rails checkbox is always checked in the dom. How can I make it so when the page loads it's checked if the object is true or not?

= f.check_box :split_funding, {class: "split_funding", :disabled => @survey.completed?, id: "split_funding_#{school.id}", "data-attribute" => "split_funding", "data-id" => school.id}

Answer 1

Pass it the checked attribute like so:

= f.check_box :split_funding, {checked: @survey.split_funding, class: "split_funding", :disabled => @survey.completed?, id: "split_funding_#{school.id}", "data-attribute" => "split_funding", "data-id" => school.id}

I'm not sure what you mean by 'if the object is true', so I am assuming that :split_funding will return true/false. If it's a relation, you can chain :present? on the end to check for presence of the relation.
