I have a route:
http://127.0.0.1:3000/professor?roles=1
Now In my view file I have a checkbox, and I want to check if roles = 1 I want checkbox to be checked, if not, it must be unchecked.
I tried this:
<input type="checkbox" <%= (!@roles.blank? && !@roles.include?(0) ? " checked='checked' " : "") %> />
No errors, but it's not working.
Query parameters are available in the params
hash:
# http://127.0.0.1:3000/professor?roles=1
params[:role] #=> "1"
Note that the values are strings.
There's also a check_box_tag
helper:
<%= check_box_tag nil, nil, params[:role] == "1" %>
You could also set an instance variable in your controller action:
def index
@role = params[:role].to_i
# ...
end
and use that in your view instead:
<%= check_box_tag nil, nil, @role == 1 %>
