tastypie posting and full example
- by Justin M
Is there a full tastypie django example site and setup available for download? I have been wrestling with wrapping my head around it all day. I have the following code. Basically, I have a POST form that is handled with ajax. When I click "submit" on my form and the ajax request runs, the call returns "POST http://192.168.1.110:8000/api/private/client_basic_info/ 404 (NOT FOUND)" I have the URL configured alright, I think. I can access http://192.168.1.110:8000/api/private/client_basic_info/?format=json just fine. Am I missing some settings or making some fundamental errors in my methods? My intent is that each user can fill out/modify one and only one "client basic information" form/model.
a page:
{% extends "layout-column-100.html" %}
{% load uni_form_tags sekizai_tags %}
{% block title %}Basic Information{% endblock %}
{% block main_content %}
{% addtoblock "js" %}
<script language="JavaScript">
$(document).ready( function() {
$('#client_basic_info_form').submit(function (e) {
form = $(this)
form.find('span.error-message, span.success-message').remove()
form.find('.invalid').removeClass('invalid')
form.find('input[type="submit"]').attr('disabled', 'disabled')
e.preventDefault();
var values = {}
$.each($(this).serializeArray(), function(i, field) {
values[field.name] = field.value;
})
$.ajax({
type: 'POST',
contentType: 'application/json',
data: JSON.stringify(values),
dataType: 'json',
processData: false,
url: '/api/private/client_basic_info/',
success: function(data, status, jqXHR) {
form.find('input[type="submit"]')
.after('<span class="success-message">Saved successfully!</span>')
.removeAttr('disabled')
},
error: function(jqXHR, textStatus, errorThrown) {
console.log(jqXHR)
console.log(textStatus)
console.log(errorThrown)
var errors = JSON.parse(jqXHR.responseText)
for (field in errors) {
var field_error = errors[field][0]
$('#id_' + field).addClass('invalid')
.after('<span class="error-message">'+ field_error +'</span>')
}
form.find('input[type="submit"]').removeAttr('disabled')
}
}) // end $.ajax()
}) // end $('#client_basic_info_form').submit()
}) // end $(document).ready()
</script>
{% endaddtoblock %}
{% uni_form form form.helper %}
{% endblock %}

I made the user field of the ClientBasicInfo nullable and the POST seems to work. I want to try updating the entry now. Would that just be appending the pk to the ajax url? For example /api/private/client_basic_info/21/? When I submit that form I get a 501 NOT IMPLEMENTED message. What exactly haven't I implemented? I am subclassing ModelResource, which should have all the ORM-related functions implemented according to the docs.
