ruby on rails - wrong number of arguments (0 for 3..6) -

i using mailboxer gem , looking have questions sent users inbox can view , answer question.

i receiving argument error wrong number of arguments (0 3..6). points line @message = current_user.send_message.new(:subject => "you have question #{@question.sender_id}",

i trying use send message instance since original line of code @message = current_user.messages.new(:subject => "you have question #{@question.sender_id}" submit question notifications table, not connect conversations table.

questions controller:

def create   @question = question.new(params[:question])   if @question.save     #original code @message = message.create     @message = current_user.send_message.new(:subject => "you have question #{@question.sender_id}",                            #original code :sender_id                            :notification_id => @question.sender_id,                            #original code :recipient_id                            :receiver_id => @question.recipient_id,                            :body => @question.question)      @question.message = @message     @question.save     redirect_to questions_path, notice: 'your question saved successfully. thanks!'   else     render :new, alert: 'sorry. there problem saving question.'   end end 

you getting error because send_message method (provided mailboxer gem) requires 3..6 arguments , not sending arguments it.

also, looking @ code, seems trying save message record question. so, @message should set as:

@message = current_user.message.new(:subject => "you have question #{@question.sender_id}",                            #original code :sender_id                            :notification_id => @question.sender_id,                            #original code :recipient_id                            :receiver_id => @question.recipient_id,                            :body => @question.question) @question.message = @message @question.save 

note used current_user.message.new instead of current_user.send_message.new.

edit

for using send_message, @ least need pass 3 arguments:

send_message(recipient, "body", "subject") 

where recipient person receiving message.

i not sure why chaining new method after send_message(as called create new instance of class).

you can call send_message follows:

 @message = current_user.send_message(@question.recipient_id, @question.question, "you have question #{@question.sender_id}")
