ruby-on-rails – Capybara Rspec测试可能对AJAX失败 – 测试con

rspec的

describe 'editing contenteditables',js: true do
  before do
    page.find('#artistdescription').set('Pizza')
    page.find('#similarArtists').click #in order to blur out of contenteditable
  end

  it {should have_content('Pizza')}
end

视图

<% if @is_current_artist %>
  <% description_text = (@artist.description.blank? && @is_current_artist) ? "test" : @artist.description %>
  <textarea contenteditable='true' id='artistdescription'>
    <%= description_text %>
  </textarea>
<% else %>
  ...

AJAX

$(document).on('blur','#artistdescription',->
  $.ajax(
    url: "/artists/" + $('#idnumber').html()
    type: "PATCH"
    datatype: "JSON"
    data: {
      artist: {
        description: $('#artistdescription').val().replace(/(<([^>]+)>)/ig,"")
      }
      session_code: getCookie('session_code');
    } 
  )
)

调节器

def update
    @artist = Artist.find(params[:id])
    p 'Hello from update'
    return if !active_session && !is_current_artist
    p 'Logged in!'
    pp artist_params
    @artist.update_attributes(artist_params) #error here

  def artist_params
    #Add more contenteditable stuff here
    p '=====================TASTY TACOS!'
    pp params
    params.require(:artist).permit(:artist_name,:route_name,:password,:email,:background_image,:description,:hometown,:genre) #error here
  end

这是我的错误信息

"Hello from update"
"Logged in!"
"=====================TASTY TACOS!"
{"action"=>"update","controller"=>"artists","id"=>"1"}
