   • What does “state transfer” in Representational State Transfer (REST) refer to?

     Top Answer

     Answered Jan 05, 2011 · 21 votes

     Why? What does state (as I understand it, something like a session) have to do with a representation of a resource?

     An object has attributes (or state) and behaviors (or methods).

     If I want to move an object from my desktop to a server I have to do the following:

     • Create a representation of the state of the object.
     • Transfer that representation from the desktop to the server.

     The methods I don't transfer. I install the same class definition on both machines.

     So, REST is about creating a representation of the object's current state so it can be transferred to another server from which the object can be reconstructed.

     We only send the state -- the attributes -- of the object. And we have to create an external, serialized representation of that state.

   • Define CSS style in Django model field

     Top Answer

     Answered Aug 04, 2013 · 2 votes

     Create a form from the model and define UI attributes there, that is the correct place to do it e.g.

     class MyForm(ModelForm): class Meta: model = MyClass fields = ('my_field') widgets = { 'my_field': TextInput(attrs={'class': 'mycssclass'}), }

     That should set correct class for your field, then in HTML file set the needed css attributes e.g.

     .mycssclass { color: red;}-

     If you are using inlineformset_factory you can still pass a widgets dict to it, where widgets is a dictionary of model field names mapped to a widget, or you can pass a custom form to it, so you can do something like this

     MyClassFormSet = inlineformset_factory(User, MyClass, form=MyForm, can_delete=False, extra=5)-

   • Architectural style for hybrid of client-server and publish-subscribe

     Top Answer

     Answered Dec 07, 2012 · 2 votes

     Blended styles are common in complex systems. The most important thing is to make sure that the quality attributes promoted by the styles used complement one another and do not create tension. Tension created would, obviously, need to be addressed.

     There seems to be a hidden quality attribute, "files on the client-side are not actually changed until the server responds to the command" which indicates why you chose to use a call-return style in addition to publish-subscribe. I do worry about having a blocking call here for performance, but you also need to worry about data integrity issues.

     Thinking about this a little, it seems like you might be able to use a pure publish-subscribe style with the right set of messages.

     In terms of "the right style to use" -- focus on your quality attributes and be specific about what is promoted and inhibited by your design decisions. Based on what you've written here, I think there are some additional scenarios that need to be fleshed out to really make a strong case for one style over another right now.

   • Define abstract class with abstract methods in pattern design style

     Top Answer

     Answered Apr 15, 2012 · 2 votes

     I guess what you want is something like this:

     public abstract class GameCharacter{- protected abstract doAttackTwo();- protected final doAttackOne() { ... implement here ... } ...}

     doAttackTwo() must be implemented by the subclasses, whereas doAttackOne() cannot be overridden.

   • Architectural considerations in designing console applications?

     Top Answer

     Answered May 03, 2009 · 10 votes

     It sounds as if you're building an interface that performs one of several distinct operations with each invocation. I'm not sure if you're referring to a "command-line" application (which does one action, then exits) or a CLI application (which displays a prompt and responds repeatedly to user input). In general, the former will be much simpler to build than the latter; I think it only makes sense to use a CLI if your application requires some persistent state that evolves over multiple commands. If you are tackling something like this, then alphazero is correct -- you should probably learn about REPLs and copy a good one.

     In any case, the operation performed will depend on the arguments passed on the command-line, so I'll brainstorm about that part...

     It's sensible think of the application as a set of distinct "Command" objects, one for each type of operation. The entry-point to the application should thus be a some sort of CommandLineDispatcher object that dispatches requests to the appropriate Command object.

     To be modular, the dispatcher should be configured with an abstracted mapping (eg, a Hashtable) to associate each command token (usually the first word of the command-line string) to the Command object that handles it. The dispatcher may also handle common options-parsing, probably using some off-the-shelf "getopts" library to do the heavy lifting.

     To start simple, each Command object could implement a consistent interface for doing its work; maybe something like this:

     public void execute(List<String> args)-

     This way, the entry-point dispatcher just finds the Command being requested, and executes it.

     Regarding error-handling: the execute() method might just throw an exception to communicate errors... Exception could be caught and processed by the dispatcher, or simply logged to the screen. Alternatively, failing Commands could invoke some shared usage function to combine an error message with general instructions. I don't think the "entry point" should necessarily be made aware of problems as you suggest; if you need robust error-handling (eg, for logging or alerting capabilities), this seems like it belongs in a separate component that could be provided to the Command object.

     In general, a command-line application is no different than any other application that responds to user input -- you'll need a dispatcher to parse and route the input, and handlers (aka "controllers") to execute the supported operations. If you need other services (logging, alerting, database connectivity, etc), you'll do well to create separate components to isolate this logic and expose it with clean interfaces.
