views

问题 I have a Drupal website where I post tournament results. I have created a content-type where i write the result for 1 person in the tournament. So the fields are like: Date of tournament, player name, final position. If 10 people played in the tournament, I create this content for each player. Now, I would like to create a table with views, to list all the players in the tournament, and the various info, like player name/final position. I can do that pretty easy by adding the fields and

问题 I was wondering if there exists a tool for Neo4j that can read an XSD file and use it to enforce a schema on Neo4j. I'm newbie on graph databases but I'm starting to appreciate the schema-less approach. There's a lot of projects out there that have been pumping in a lot of non-sequential data and making sense of it all which is really cool. I've come across some requirements that call for control on what properties a node or edge can have given a certain label and what labels an edge can have

问题 I would really like to create a comment to a view with a short description of its purpose. Unfortunately it is not possible to create comments to views in oracle. This feature is only for tables, columns and materialized views available. I would like to know how you do describe your database views? 回答1: Try: comment on table <name> is 'text'; The command works on views. For example: CREATE OR REPLACE VIEW MY_VW AS SELECT 1 FROM DUAL; COMMENT ON TABLE MY_VW IS 'Clever comment.'; 回答2: Its

问题 this is a rather basic question (I'm new to Django) but I'm having trouble using a variable set in my view inside my template. If I initialize a string or list inside my view (i.e. h = "hello") and then attempt to call it inside a template: {{ h }} there is neither output nor errors. Similarly, if I try to use a variable inside my template that doesn't exist: {{ asdfdsadf }} there is again no error reported. Is this normal? And how can I use my variables within my templates. Thanks! 回答1: In

问题 I have been using clearcase snapshot views in my current project. so, it requires update to refresh content. does it mean any update I do on view is updated to the servers and any updates others do are updated to my view? . Also, If I try to checkout a file in snapshot view which somebody else has already checked out in his snapshot view but not updated, will I succeed? 回答1: does it mean any update I do on view is updated to the servers? Only if you do a cleartool checkin (commit the new

问题 I want to allow the user to create "custom screens" dynamically by selecting from a existing set of fields at runtime i.e., everything should be done on App on the phone. For example - existing set of fields = {name, location, picture, age} . User A wants to create a new screen with fields name, location and age. and User B wants to have a screen with only name and picture. These screens should be persistent and should be able to save, query and edit information in a local database on the

问题 At which point are Android views created? When the activity starts? When the app is started? When a call to setContentView() is made? Or at some other point? 回答1: You mean when is it safe to get the objects of your view? If you refer to Activities, in the onCreate method, after you call setContentView(...) you can start calling findViewById(...) to refer to the objects of your view. In the case of Fragments, the view is created in the onCreateView(...) method. You can refer to the view in the

问题 On a TabBar-based application on the iPad, is there a way to present a modal on top of it in "FullScreen"? I have a LANDSCAPE ONLY APP (if that makes a difference) and the item I want to currently present modally I would like to present full screen, filling the entire screen just to clarify. I can present it in "PageSheet" fine, and "FormSheet" is all right, after a few button adjustments on the modal view nib, but once I try "FullScreen", the background goes white (TabBar still there, though

问题 I have the answer for the Rails 2.X but not for Rails 3. How can I read the name of a current layout rendered inside a view. My Rails2 question: Rails Layout name inside view Thx. 回答1: Getting this to work in Rails 3.2 is a little more complicated than previously outlined. If your controller explicitly declares a layout, then the result of controller.send(:_layout) is a String, but otherwise it's an ActionView::Template. Try this: module ApplicationHelper def current_layout layout =
