问题 What is an efficient way to implement a multiple file client upload service? Are there any popular libraries for that? Basically I'm looking at a Web view, served a client, that would allow them to upload files: i.e browse their file system and choose say up to 6 files. Is implementing the above service better than a single file upload-service. i.e allowing only one upload at a time? If so what is an efficient way to implement that or again what popular libraries are there to use. I'm

问题 I would like to wrap a non-Traits model class for use with Python Traits. My goal is to write a Traits-based UI to manipulate an "external" model class. The external model class has been generated by SWIG and so I cannot add enthought.traits.api.HasTraits as an ancestor (I think, though I may be wrong). My current best attempt is from enthought.traits.api import HasStrictTraits, Property, Instance class ExternalModel(): foo = 'foo' class TraitsModel(HasStrictTraits): _e = Instance

问题 In my ZF 1.11 application I'm storing my translator in registry like this: Zend_Registry::set('Zend_Translate', $translator); So in my view scripts I can access the translator this way: $this->translate('abc'); Is there any clever way to be able to use this call instead: $this->_('abc'); Using $this->translate clutters the views, and lot's of people are used to seeing _() anyway. 回答1: Whereas I generally agree with the notion that function/method names should be meaningful, I also agree that

问题 I am and android developer and I have worked on all of these three architecture patterns in my applications. Also I have gone through several post's on stackoverflow about the difference of each. My understanding might not be 100% correct but this is what I know so far in brief. MVC - User input is received by controller. Controller updates the model then tells the view to update itself. MVP - View gets the user input and notify the Presenter. Presenter gets the data from Model and then sends

问题 This is my controller: def addcar @car = Car.new(params[:car]) render :action => "list" end this is my view: <%(@allcars).each do |cell|%> <p><%= link_to cell.to_s, :controller => "car", :action => "addcar", :car => cell.to_s %></p> <%end %> In the link_to statement I want to pass cell.to_s to the controller. How can I do that please? The cell.to_s is just a string but I want it to be the name of the car object ( car.Name ) 回答1: Car.new(params[:car]) expects params[:car] to be a Hash ( {:foo

问题 how can I pull masterpage content from the database and pass that into the masterpage so that my Views inherits from it? This is an example: Clients to the website will have a unique code, lets call it "TargetCode", for example, ABC123, ABC456, etc... This unique code will be entered in the querystring, for example: mysite.com/ABC123. Each of those "TargetCode" will have a different CSS, name, address, phone number, (common to all pages, so these will be placed in the master page) and page
