    <p><strong>Does anyone know how to specify the ContentType of the Post to json/application?</strong> I thought I was, and backbone did it by default, but judging by the fact it's saying it's getting plain text (see comments), I guess I need to figure out another way to specify it.</p> <p>I am using Backbone.js and I am trying to POST to the TastyPie API that is no longer read only and I am receiving a 500 error when I try to make a model and .save() it. This is a code snippet I am using for my sync that i found here: <a href="http://documentcloud.github.com/backbone/docs/backbone.html#section-124" rel="nofollow">http://documentcloud.github.com/backbone/docs/backbone.html#section-124</a></p> <pre><code> Backbone.sync = function(method, model, options){ var type = methodMap[method]; var params = _.extend({ type: type, dataType: 'json' }, options); if (!params.url){ params.url = getUrl(model) || urlError(); } if (Backbone.emulateJSON){ params.contentType = 'application/json'; params.data = params.data ? {model: params.data} : {}; } if (Backbone.emulateHTTP){ if(type === 'PUT' || type === 'DELETE'){ if (Backbone.emulateJSON) params.data._method = type; params.type = 'POST'; params.beforeSend = function (xhr){ xhr.setRequestHeader('X-HTTP-Method-Override', type); }; } } if (params.type !== 'GET' &amp;&amp; ! Backbone.emulateJSON){ params.prorcessData = false; } return $.ajax(params); }; $.fn.serializeObject = function() { var o = {}; var a = this.serializeArray(); $.each(a, function() { if (o[this.name] !== undefined) { if (!o[this.name].push) { o[this.name] = [o[this.name]]; } o[this.name].push(this.value || ''); } else { o[this.name] = this.value || ''; } }); return o; }; $(function() { $('form').submit(function() { var dict = $('form').serializeObject(); var new_task = new Backbone.Model({ date: toString(dict.date), name: toString(dict.name), priority: toString(dict.priority)}); console.log("new_task =" + new_task); new_task.save(); console.log(dict); return false; }); }); }); </code></pre>

    1. COthat's the "regular" backbone.sync right? what 500 response do you get? i recently made an app combining tastypie with backbone. you can check it out here: https://github.com/c4urself/ratebeer maybe it'll give you some ideas.

    3. COOne obstacle here is that, though Paul's solution is correct, Tastypie does not yet support X-HTTP-Method-Override headers. You could use something like this to add, or directly extend the Resource class you're using with the overridden method: https://gist.github.com/2161338

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
