Recordselect form doesn't appear on Rails 3.1 (asset pipeline enabled) and Active Scaffold

[Andrey Novikov]

I'm upgrading from Rails 3.0 to 3.1 (one step in upgrade from Rails 2)

In rails 3.0 I use these versions in Gemfile, and everything works well

gem "active_scaffold", "~> 3.0.0"
gem "recordselect", "~> 3.0.4"

I've upgraded to Rails 3.1 and have enabled asset pipeline, after that recordselect form no longer appears anywhere (e.g.: while editing record of ChargeCard model, which belongs to Discipline model, config.columns[:discipline].form_ui = :record_select is set). Current Gemfile:

gem "active_scaffold", "~> 3.1.0"
gem "recordselect"

I've tried 3.1.9 and 3.2.3 versions of recordselect, latest version from git://github.com/scambra/recordselect.git , tried 3.1 and 3.2 versions of active_scaffold and result was the same: form just doesn't appeared. Asset pupeline have load proper version of recordselect's javascript, on click on the recordselect input the query to the disciplines/browse?escape=false was sent and successfully returned with html and javascript for form. No errors appeared in developer tools javascript console. Can't understand.

Do you know if you're using jquery or prototype? I have recordselect working successfully for me with rails 3.2.2, jquery, latest official active_scaffold, and recordselect from github.com/scambra/recordselect.

In my experience, if the form doesn't appear, its something with the javascript library or javascript not being loaded in the asset pipeline. Sounds like you've already checked that though...

Fixed it!

I found, that on click in recordselect field the is RecordSelect.Abstract.open function is fired (from https://github.com/scambra/recordselect/blob/master/app/assets/javascripts/jquery/record_select.js#L219), that contains ajax call with success callback, but that callback doesn't fire.

I've put the next code into developer tools console:

$.ajaxSetup({

  error: function (XMLHttpRequest, textStatus, errorThrown) { alert("Error!\n"+textStatus); }

});

And got a "parsererror" message.

Server returns answer from browse?escape=false with text/javascript mime-type and HTML-data. It caused jQuery to fail ajax-request with "parser error" reason, but source ajax call from jquery/record_select.js:222 haven't an error callback to catch that situation.

In my app assets javascripts I've found next code (added a long, long time ago for now unknown reason):

// makes Rails to know that jQuery Ajax requests should be processed as .js format

$.ajaxSetup({

    'beforeSend': function(xhr) {xhr.setRequestHeader("Accept", "text/javascript")}

});

After I've removed it and cleared the cache (dammit cache!) form is become to appear (server now returns text/html).

Thanks for attention. Sorry for my English :-)
