tastypie posting and full example

Question

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',

                    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>')

                    }
                }) // end $.ajax()

            }) // end $('#client_basic_info_form').submit()

Edit:

My resources file is now:

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.

Answer 1

Okay, I figured it out. I wasn't being careful. The AJAX request type should have been "PUT" to handle the 501 not implemented error (I was performing an update). I have also set up a custom authentication class to handle 403 errors.
