You should know how to write custom template tags in Django. For example, the following tag lets me JSONify Django variables in the template. 

<pre><code>@register.filter
def jsonify(o):
 return mark_safe(simplejson.dumps(o))
</code></pre>

This is useful because my website is all Javascript, so I use the Django templates to make a no-script version of the site as well. This is mostly useful so Google can crawl my site. For example, look at the following page with Javascript on and off: <a href="http://www.trailbehind.com/Yosemite%20National%20Park/" rel="nofollow noreferrer">http://www.trailbehind.com/Yosemite%20National%20Park/</a>

Here's some other useful tags I have:

<pre><code>@register.filter
def attr_name(id):
 return util.get_attribute(id).name


@register.filter
def dashes(name):
 return name.replace(' ', '-')
</code></pre>

And doesn't Python's decorator syntax make these short and sweet?

<a href="http://www.springsource.org/webflow" rel="nofollow noreferrer">Spring Web Flow</a> - Serialized conversations / great browser back button support

Supporting the browser back button and history is a headache with most web apps out there, simply because it's too easy for the client's perceived state / page to get out of sync with what's on the server.

SWF solves this by creating snapshots of the entire conversation state each time a view is rendered. Most stateful data is stored in one of SWF's additional scopes (conversation, flow, view), and is thus serialized with the conversation snapshot.

SWF's URLs don't identify a resource like a page or an action. Instead, they identify a flow and a conversation. Since SWF implements POST-REDIRECT-GET implicitly, each time a page is rendered the URL contains the flowExecutionId, which uniquely identifies the conversation and the serialized conversation snapshot. Thus, as the user uses the browser back button or history, each URL actually restores the entire conversation state at that point in time. 

This results in ideal back button handling: client state is never out of sync with conversation state, and the user can freely continue from any previous state.

Developers can also discard or invalidate history (saved snapshots) when users perform certain actions. This is good for user actions which modify something in the database, since the user should not have the ability to go back to a state which doesn't represent what's in the database. 

The developer can restrict exactly how many snapshots to save. Since hard drive capacity is plentiful, especially in comparison to memory, it's a fairly neat solution.

One major restriction, however, is that any attribute placed in conversation, flow, or view scope must be Serializable.

<a href="http://www.springsource.org/webflow" rel="nofollow noreferrer">Spring Web Flow</a> - Flow and view scope

Most web apps are content to use the Servlet defined scopes of request, session, and context. However, much of the stateful data used in a web app doesn't quite fit into any of these scopes. Typically, such data lasts longer than a single request, but shorter than a session. Session scope is usually used in this case. This forces the developer to essentially perform manual memory management to place things into session scope, and then explicitly remove them when they are no longer needed for that portion of the application. This can be troublesome, as there are usually multiple places where attributes must be removed, as there are often several actions that the user can invoke to take them out of the use case where the attributes are needed. 

In large or growing applications, attribute cleanup code becomes a necessary and pervasive clutter throughout the code. Forgetting to clean up attributes, or cleaning up the wrong ones by mistake, can introduce bugs. 

SWF solves this by providing some additional scopes which better fit the life cycle of application attributes.

SWF introduces the concepts of flows, which are reusable modular groupings of behavior represented as a state machine consisting of states and transitions between them. A flow may include action-states for invoking server-side behavior, view-states for rendering pages to the user, and others. Flows often represent use cases. Flow-scoped attributes persist for the duration of the flow, and are cleaned up automatically when the flow ends. This results in attributes which only persist for the duration of the use case where they are needed.

ViewStates within a flow render a view to the user. Transitions from a viewState may navigate to a different state or can remain in the same viewState, rerendering the view (with or without AJAX) after performing some actions. Attributes in viewScope persist while control remains in the viewState. ViewScoped attributes survive browser refreshes, and are useful for data that is relevant only for the view being rendered, such as data which is used in AJAX requests, or for flags which influence the markup in some way. When a transition is invoked which leaves the viewState, viewScoped attributes are cleaned up.

In summary, SWF's additional scopes better fit the lifecycle of application attributes, and using these additional scopes removes the need to manually manage your attributes, resulting in less attribute-juggling plumbing code throughout your app and less potential for bugs.

There are a lot of web application frameworks out there, based in Java/Ruby/Python/PHP amongst others. I'm keen to discover, compare and contrast features that are unique to individual frameworks.

Which framework feature do you think is useful and why is it important to know about?

e.g.

<ul>
<li>Stripes: FlashScope - Flash scope is useful since it allows for temporary use of the session to store information between two requests. An alternative to putting information in as a URL parameter or implementing custom logic to remove a parameter after use. 
<a href="http://stripes.sourceforge.net/docs/current/javadoc/net/sourceforge/stripes/controller/FlashScope.html" rel="nofollow noreferrer">http://stripes.sourceforge.net/docs/current/javadoc/net/sourceforge/stripes/controller/FlashScope.html</a></li>
</ul>

Can you please limit to one feature per post.

Summary:

<ul>
<li>Stripes - Flash Scope</li>
<li>Django - JSONified variables in templates</li>
<li>Symfony - model generation. Backend administration generation</li>
<li>Grails - Powerful ORM in the form of GORM</li>
<li>Seaside - no relational database, just code OO</li>
<li>Sinatra - Minimalism</li>
<li>Spring Web Flow - Flow and view scope</li>
</ul>

有很多web应用程序框架()都是基于/Ruby/PHP等。我热衷于发现、比较和对比各个框架特有的特性。您认为哪个框架特性是有用的，为什么了解它很重要？例如：条纹: FlashScope - Flash作用域非常有用，因为它允许临时使用会话在两个请求之间存储信息。将信息作为URL参数或实现自定义逻辑以在使用后删除参数的替代方法。你能不能把每个帖子的功能限制在一个.上摘要：条纹-闪光范围Django
