blocks|key|2003936|text|save的第一个参数是要保存在模型上的属性：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2003937|this.model.save(+{att1+:+"value"},+{success+:handler1,+error:+handler2});|code-block|syntax|javascript|2003938|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

The first argument of save is the attributes to save on the model:

<pre><code>this.model.save( {att1 : "value"}, {success :handler1, error: handler2});
</code></pre>

blocks|key|383566|text|所以我有点困惑--我仍然需要传入所有属性才能调用一个save事件吗？如果我的模型很大..我不希望手动设置每个属性|type|unstyled|depth|inlineStyleRanges|entityRanges|data|383567|我正在调用model.save并尝试执行以下操作：|383568|this.model.save(
++++{

++++++++++++console.log('model+saved');

++++});|code-block|syntax|javascript|383569|好吧，为了回答我自己的问题，以防有人发现这篇文章，我做了以下工作：|383570|this.model.save({+id:+this.model.get('id')+},

so im a little confused - do i still need to pass in all attributes in order for me to call a save event? what if my model is large.. i dont wish to set every property manually

im calling model.save and attempting to do the following:

<pre><code>this.model.save(
 {
 success: function (model, response) {
 console.log('model saved');
 }
 });
</code></pre>

ok just to answer my own question incase anyone finds this post, i did the following which works:

<pre><code>this.model.save({ id: this.model.get('id') },
 {
 success: function (model, response) {
 console.log("success");
 },
 error: function (model, response) {
 console.log("error");
 }
 });
</code></pre>

EDIT: I couldn't reply to you for some reason, but I can edit

but you don't have to set id: <code>this.model.get('id')</code> you can just pass a blank object because a blank attribute just won't extend attributes, does nothing:

<pre><code>this.model.save({}, {
 success: function (model, response) {
 console.log("success");
 },
 error: function (model, response) {
 console.log("error");
 }
});
</code></pre>

blocks|key|2003986|text|您可以使用下划线lib，如下所示，因为backbone已经依赖于此。记住，save的第一个参数必须具有属性，或者您可以只传递{}，以防您想要保存模型本身。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2003987|this.model.save({},+_.bind(function(model,+response){
++//Do+whatever+you+want+e.g.
++this.collection.add(model)
},+this))|code-block|syntax|javascript|2003988|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

You may use underscore lib as follows as backbone already depends upon this. Remember first argument of save must either have attributes or you may just pass {} in case you want to save model itself.

<pre><code>this.model.save({}, _.bind(function(model, response){
 //Do whatever you want e.g.
 this.collection.add(model)
}, this))
</code></pre>

blocks|key|2004031|text|出于某些未知的原因，上面的方法对我都不起作用。在我的例子中，只是api没有被击中。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2004032|但后来在搜索时，我遇到了this+link，在那里有人尝试了null而不是{}作为第一个参数。|offset|length|style|CODE|2004033|this.model.save(null,+{

});|code-block|syntax|javascript|2004034|所以，这对我很有效。希望这对你也有帮助。|2004035|entityMap|0|LINK|mutability|MUTABLE|url|https://github.com/dhruvaray/backbone-associations/issues/1^0|0|U|4|11|2|C|9|0|0|0|0^^$0|@$1|2|3|4|5|6|7|W|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|X|8|@$D|Y|E|Z|F|G]|$D|10|E|11|F|G]]|9|@$D|12|E|13|1|14]]|A|$]]|$1|H|3|I|5|J|7|15|8|@]|9|@]|A|$K|L]]|$1|M|3|N|5|6|7|16|8|@]|9|@]|A|$]]|$1|O|3|-4|5|6|7|17|8|@]|9|@]|A|$]]]|P|$Q|$5|R|S|T|A|$U|V]]]]

For some unknown reason, none of the above method worked for me. The api only was not hit in my case.

But later while searching on this, I bumped into <a href="https://github.com/dhruvaray/backbone-associations/issues/1">this link</a>, where some one had tried <code>null</code> instead of <code>{}</code> as the first parameter.

<pre><code>this.model.save(null, {
 success: function (model, response) {
 console.log("success");
 },
 error: function (model, response) {
 console.log("error");
 }
});
</code></pre>

so, this worked for me. Hope this helps you too.

blocks|key|2004089|text|您的服务器必须返回一个JSON对象。如果响应不是JSON对象，则不会触发回调。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2004090|如果您的服务器没有成功返回JSON对象，请使用dataType:"text"选项执行保存，如下所示：|offset|length|style|BOLD|2004091|this.model.save([],{
+dataType:"text",
+success:function()+{},
+error:function()+{}
});|code-block|syntax|javascript|2004092|使用此选项，它将不会等待JSON响应，而是等待文本，因此将启动回调。|2004093|entityMap^0|0|N|F|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|R|8|@$D|S|E|T|F|G]]|9|@]|A|$]]|$1|H|3|I|5|J|7|U|8|@]|9|@]|A|$K|L]]|$1|M|3|N|5|6|7|V|8|@]|9|@]|A|$]]|$1|O|3|-4|5|6|7|W|8|@]|9|@]|A|$]]]|P|$]]

Your server must return a JSON object. If the response is not a JSON object, the callbacks will not fire.

If for success your server doesn't return a JSON object, perform a save with dataType:"text" option, like this:

<pre><code>this.model.save([],{
 dataType:"text",
 success:function() {},
 error:function() {}
});
</code></pre>

With this option it will not be waiting for a JSON in response, but a text, and thus the callback will be launched.

blocks|key|383736|text|对于那些希望在不更新属性的情况下保存模型的用户，可以执行以下操作：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|383737|model.once("sync",+function(model,+response,+options){
++++//
});
model.once("error",+function(model,+response,+options){
++++//
});
model.save();|code-block|syntax|javascript|383738|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

For those that want to save a model, without updating the attributes, you can do the following:

<pre><code>model.once("sync", function(model, response, options){
 //
});
model.once("error", function(model, response, options){
 //
});
model.save();
</code></pre>

blocks|key|383763|text|在初始化函数中，将同步方法绑定到您定义的方法(onSaveSuccess)|type|unstyled|depth|inlineStyleRanges|entityRanges|data|383764|++++++++++++initialize:+function+(options)+{
++++++++++++++++++++this.model.on('sync',+_.bind(this.onSaveSuccess,+this));
},
++++++++++++onSaveSuccess:+function()+{
++++++++++++++++console.log('saved');
++++++++++++++++this.render();
++++++++++++},|code-block|syntax|javascript|383765|这样，无论何时运行this.model.save()，如果同步成功，它都会将onSaveSuccess函数作为回调函数运行|383766|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

In you initialize function, bind the sync method to a method you define (onSaveSuccess)

<pre><code> initialize: function (options) {
 this.model.on('sync', _.bind(this.onSaveSuccess, this));
},
 onSaveSuccess: function() {
 console.log('saved');
 this.render();
 },
</code></pre>

This way, any time you run this.model.save(), it will run the onSaveSuccess function as a callback if your sync is successful

<pre><code>this.model.save({
 success: function(model, response){
 console.log('success');
 },
 error: function(){
 console.log('error');
 }
})
</code></pre>

The model is correctly posted to the server which handles the save, but the success callback is not fired. Do I need to send something back from the server ?

How do I trigger the success callback on a model.save()?
