如何在Ruby中将Ruby参数传递给表单

Question

I have next form:

.well
  = form_for @message, data: { chanell: @chanell }, remote: true do |f|
    .form-group
      = f.label :body, "Enter your message:"
      = f.text_area :body, rows: 3, class: 'form-control', required: true, maxlength: 2000
      %small.label.label-warning Cannot be blank or contain more than 2000 symbols.
      = hidden_field_tag 'chanell', @chanell

    = f.submit 'Send', class: 'btn btn-primary btn-lg'

How do i pass chanell to method client.publish in file /messages/create.js.rb

publisher = client.publish("<% params[:chanell] %>", {
  message: "<%= escape_javascript( render(:partial => @message, :layout => false))%>"
});

publisher.callback(function() {
  $('#message_body').val('');
  $('#new_message').find("input[type='submit']").val('Submit').prop('disabled', false)
});

publisher.errback(function() {
  alert('There was an error while posting your message.');

});

Answer 1

try this

publisher = client.publish("<%= params[:chanell] %>", {
  message: "<%= escape_javascript( render(:partial => @message, :layout => false))%>"
});
