Mercury editor not saving edited values in Rails 4.2

Question

I followed Railscast Tutorial to set up mercury editor.

mercuy.js

$(window).bind('mercury:ready', function() {
  var link = $('#mercury_iframe').contents().find('#edit_link');
  Mercury.saveUrl = link.data('save_url');
  link.hide();
});

$(window).bind('mercury:saved', function() {
  window.location = window.location.href.replace(/\/editor\//i, '/');
});

views/quotations/show.html.erb

<p><%= link_to "Edit Page", "/editor" + request.path, id: "edit_link", data: {save_url: mercury_update_quotation_path(@quotation)} %></p>

mercury.html.erb

  new Mercury.PageEditor(saveUrl, {
    saveStyle:  'form', // 'form', or 'json' (default json)
    saveMethod: null, // 'PUT', or 'POST', (create, vs. update -- default PUT)
    visible:    true  // boolean - if the interface should start visible or not
  });

routes.rb

  resources :quotations  do
    member { post :mercury_update}
  end

It shows the following error

Mercury was unable to save to the url: http://localhost:3000/quotations/1

Console output

Started PUT "/quotations/1" for 127.0.0.1 at 2015-03-07 19:20:49 +0530

AbstractController::ActionNotFound (The action 'update' could not be found for QuotationsController):

It worked well for static id's but not like this. Please help me to solve this error.

Answer 1

Your error is telling you

ActionNotFound 

Meaning you are missing the mercury_update in your QuotationsController. Try adding

def mercury_update
  quote = Quotations.find(params[:id])
  quote.FIELD_FROM_YOUR_DB = params[:content][:quotation_content][:value]
  quote.save!
  render text:""#tells mercury of successful save (I think)
end

If that doesn't work, try checking your console for the the parameters mercury is passing around. It should look something like

Started PUT "/quotations/1/mercury_update" for ...
  Parameters:{"content"=>{...}}

Notice that it is a PUT request, that's what Mercury is telling you that it's doing. Thus the route needs to be updated

resources :quotations do
  member do
    put 'mercury_update' #this may change your path to mercury_update_quotation_page_path(@quotation)
  end
end

Also, ensure that resources :quotations is not defined twice in config/routes.rb. I defined it following that tutorial and then ran

rails g scaffold quotations

in order to auto-generate views and such. This command defined quotations again at the top of my config/routes.rb as

resources :quotations
#...
resources :quotations do #... This was my definition

thus ignoring my definition with the member 'mercury_update'.

Finally, let me know if your saved response is working, as mine is not. GL!
