I'm trying
to upload a file using "AJAX", process data in the file and then return some of that data
to the UI so I can dynamically update the screen.
I'm using the JQuery Ajax Form Plugin, jquery.form.js found at http://jquery.malsup.com/form/ for the javascript and using Django on the
back end. The form is being submitted and the processing on the
back end is going through without a problem, but when a response is received from the server, my Firefox browser prompts me
to download/open a file of type "application/json". The file has the json content that I've been trying
to send
to the browser.
I don't believe this is an issue with how I'm sending the json as I have a modularized json_wrapper() function that I'm using in multiple places in this same application.
Here is what my form looks after Django templates are applied:
<form method="POST" enctype="multipart/form-data" action="/test_suites/active/upload_results/805/">
<p>
<label for="id_resultfile">Upload File:</label>
<input type="file" id="id_resultfile" name="resultfile">
</p>
</form>
You won't see any submit buttons because I'm calling submit with a button else where and am using ajaxSubmit() from the jquery.form.js plugin.
Here is the controlling javascript code:
function upload_results($dialog_box){
$form = $dialog_box.find("form");
var options = {
type: "POST",
success: function(data){
alert("Hello!!");
},
dataType: "json",
error: function(){
console.log("errors");
},
beforeSubmit: function(formData, jqForm, options){
console.log(formData, jqForm, options);
},
}
$form.submit(function(){
$(this).ajaxSubmit(options);
return false;
});
$form.ajaxSubmit(options);
}
As you can see, I've gotten desperate
to see the success callback function work and simply have an alert message created on success. However, we never reach that call. Also, the error function is not called and the beforeSubmit function is executed.
The file that I get
back has the following contents:
{"count": 18, "failed": 0, "completed": 18, "success": true, "trasaction_id": "SQEID0.231"}
I use 'success' here
to denote whether or not the server was able
to run the post command adequately. If it failed the result would look something like:
{"success": false, "message":"<error_message>"}
Your time and help is greatly appreciated. I've spent a few days on this now and would love
to move on.
