ruby on rails - check_box always submitting as 0 -


the data goes database, it's submitting :location 0. how avoid this? want :location submit checked value.

also, easier use simple_form instead of doing this?

here's partial:

<%= form_for(@offering) |f| %>      <%= render 'common/form_errors', object: @offering %>      <%= f.label :description, "description:" %>       <%= f.text_field :description %>     <%= f.label :location, "where?" %>    <%= check_box("offering", :location, {}, "alphabet city") %>alphabet city   <%= check_box("offering", :location, {}, "battery park") %>battery park   <%= check_box("offering", :location, {}, "chelsea") %>chelsea   <%= check_box("offering", :location, {}, "chinatown") %>chinatown    <%= f.submit "post offering" %>    <% end %>

here's html produces:

    <form accept-charset="utf-8" action="/offerings" class="new_offering" id="new_offering" method="post"><div style="margin:0;padding:0;display:inline"><input name="utf8" type="hidden" value="✓"><input name="authenticity_token" type="hidden" value="l6oao6csqj9tirpekg4bazj3uh6fumr9ymdyxx2hbfg="></div>          <label for="offering_description">description:</label>         <input id="offering_description" name="offering[description]" size="30" type="text">         <label for="offering_location">where?</label>        <input name="offering[location]" type="hidden" value="0">        <input id="offering_location" name="offering[location]" type="checkbox" value="alphabet city">alphabet city        <input name="offering[location]" type="hidden" value="0">        <input id="offering_location" name="offering[location]" type="checkbox" value="battery park">battery park        <input name="offering[location]" type="hidden" value="0">        <input id="offering_location" name="offering[location]" type="checkbox" value="chelsea">chelsea        <input name="offering[location]" type="hidden" value="0">        <input id="offering_location" name="offering[location]" type="checkbox" value="chinatown">chinatown         <input name="commit" type="submit" value="post offering">      </form>

so figured out.

the hidden inputs how on ride checkboxes.

so instead of check_box, i'm using check_box_tag this:

  <%= check_box_tag("offering[location]", "alphabet city") %>alphabet city   <%= check_box_tag("offering[location]", "battery park") %>battery park   <%= check_box_tag("offering[location]", "chelsea") %>chelsea   <%= check_box_tag("offering[location]", "chinatown") %>chinatown

instead of:

  <%= check_box("offering", :location, {}, "alphabet city") %>alphabet city   <%= check_box("offering", :location, {}, "battery park") %>battery park   <%= check_box("offering", :location, {}, "chelsea") %>chelsea   <%= check_box("offering", :location, {}, "chinatown") %>chinatown

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
