ruby on rails - Get checked status of checkbox in controller -

i have form in index-view create multiple checkboxes. 1 checkbox every entry. looks this:

index.html.erb

<%= form_for :user, url: usersupdate_path() |f| %>     <%= render @users %>     <%= f.submit 'test', :class => 'btn btn-primary' %> <% end %>

_user.html.erb

<%= check_box_tag "checked[#{user.id}]","#{user.id}",true %>

description: form want allow admin uncheck users - users want send controller , update attributes.

there 2 problems:

1) have refresh site until can send form controller - don't know why

2) when print array looks this:

{"1"=>"1", "2"=>"2", "4"=>"4"}

user 3 unchecked me.

what want this:

{"1"=>"true", "2"=>"true", "3"=>"false", "4"=>"true"}

but how can send checked value of checkbox controller?

in controller @ moment:

def update     flash[:success] = params[:checked]     redirect_to root_path end

thanks

the browser not serialize unchecked checkbox when sending form data, if not checked, never gets sent.

you can fix 2 ways. make action smart enough see "missing" values "unchecked", or add hidden field before each checkbox:

 <%= hidden_field_tag "checked[#{user.id}]", "false" %>  <%= check_box_tag "checked[#{user.id}]","#{user.id}", true %>

as true-values, second parameter check_box_tag value want checkbox have, can change this:

 <%= hidden_field_tag "checked[#{user.id}]", "false" %>  <%= check_box_tag "checked[#{user.id}]","true", true %>

and should want.

note if use formbuilders handle nuance you.
