ruby - How to read checkbox in rails I get to many argument to send emails -

i trying create select list of users on submit form send email. such has welcome these people website. problem can't seem iterate through list of checkbox able send email each single email. here form

<%= form_tag(invites_path) %>   <% @contacts.each |c|%>     <div>     <%= label_tag 'accept', c[:email] %>     <%= check_box_tag 'accept[]', c[:email], checked = true %>   <% end %>   <%= submit_tag "send invitations" %> <% end %> 

now invites_path controller is, c[:email] email of each users desired. here controller , having issues.

# if there more 1 checkbox selected if not params[':accept'].nil?   params[':accept'].split.each |u|   invitesmailer.invite_confirm(current_customer, u).deliver end else # 1 checkbox selected   invitesmailer.invite_confirm(current_customer,params[':accept']).deliver end 

why can't read it

if select 1 checkbox or multiple following error wrong number of arguments (2 1) line

invitesmailer.invite_confirm(current_customer,params[':accept']).deliver 

the parameters follow

{"utf8"=>"✓", "authenticity_token"=>"dnqpngrosw6bxrwayxjnrc8qoqr+a228ysmtfyucc3y=", "accept"=>["example@gmail.com", "example2@gmail.com"],"commit"=>"send invitations"} 

i note try follow tutorial check box send email ruby on rails, bit confused on checkbox

update: mailer controller

def invite_confirm(curuser,usemail)     @greeting = "hi"     @user = curuser      mail to: usemail, subject: "whereyouwhere invitation" end 

can read through following , let me know if solves issue.

first name of params

i'm pretty sure there's hackish way param named ':accept' may valid param name in case, it's not want. change instances of params[':accept'] params[:accept] or params['accept'].

second if block

change if block following code. since params[:accept] array. don't need call split on , else block not needed.

if params[:accept].present?   params[:accept].each |email|     invitesmailer.invite_confirm(current_customer, email).deliver   end end
