问题 I have a Recipe, Item, and Units table/model. I have a HABTM relationship with Recipe and Item, and I get the default multiple-select box when adding/editing Recipe. (am using Bake for everything for the most part). The problem is I need to associate quantities and units with each Item. Sample of UI I'm hoping for: A big component of it is the ability to add/delete/edit the individual items. I imagine looking at the submitted form data, and using some jquery and clone would work. But I was

问题 No matter what git clone url I use, git always clones one of my old projects from bitbucket. For example when I do something like this: git clone https://github.com/heroku/php-getting-started.git instead of cloning from heroku, I get one of my projects (always the same project) from my bitbucket repository.

问题 This might be a dumb question, but I don't get it: I have a class called Card. I want to do a shallow clone using MemberWiseClone(). In Theory Card inherits from Object. So it should be able to use MemberWiseClone(), even if MWC() is protected ?? Am I missing/forgetting something? 回答1: Card can use it. class Card { public Card Clone() { return (Card)MemberwiseClone(); } } 回答2: You can only call a protected method on an object of the (compile-time) type of the class that your code is in.

问题 I just installed the Gerrit code review system release 2.12.2. I'm managing the authentication to the web interface via LDAP. Once I logged in as the Administrator, I created a project called "testProject". I'm unable to see the SSH/Anonymous HTTP/HTTP clone URLs on the project page in the GUI (see below). The documentation says that if download.scheme is left unspecified in the config, SSH/Anonymous HTTP/HTTP download methods will be the default schemes. Also, I'm unable to clone projects

问题 Hello wizards of the internet, I want to show a hidden element ( "hold1" ) from a cloned object when it is is dropped into a certain container, called "plug1" . But what it does right now is it shows the hidden element on the main object and not on the cloned object. It's also not supposed to jump back to its original position. See this gif for an example. I believe it has something to do with the sym.getSymbol("cup1").$("hold1").show(); line, but I can't put my finger on it. Does anyone have

问题 I have a group of images within a <div> . All these images are served through a 302 instead of a 200 for security purposes (servlet serving image based on authentication). I would like to clone that <div> and append it to another container. When doing so in all browsers except Firefox, the images are not reloaded.
