One Request but Double Processing

Rails
1

Hi,

one request from the browser results in double processing. If I debug,
the corresponding controller action will be called twice. So that
behavior isn’t a log mistake.
Any ideas?

Here is the log file output.

Not until you provide the controller code.

I found the problem. It was a beginners mistake.
I work with JQuery. There were the following lines in the application.js
(I put it with the copy and paste and don’t think:))
$.ajax({
beforeSend: function(){
$(“#ajax_flash”).html(“Wird geladen…”);
},
complete: function(){
$(“#ajax_flash”).html(“”);
},
error: function(){
$(“#ajax_flash”).html(“Verbindungsfehler mit dem Server.”);
}
});
This lines causes an additional ajax request on every “normal” http
request.
Maybe I can help someone else with this fact.
