问题 There is possibility to dump DynamoDb via Data Pipeline and also import data in DynamoDb. Import is going well, but all the time data appends to already exists data in DynamoDb. For now I found work examples that scan DynamoDb and delete items one by one or via Batch. But at any rate for big amount of data it is not good variant. Also it is possible to delete table at all and create it. But with that variant indexes will be lost. So, best way would be to override DynamoDb data via import by

问题 I have a listbox that is bound to a database query result. I'm using an item template that shows the subject on one line and I want it to show preview of the body on another line. What I'm wondering is that-- obviously the body is going to be way too long to fit in there, can I somehow set it to only display the first so many characters and append an ellipses after that, like a preview? Or even something close would be fine. So for example: Instead of displaying: Lorem ipsum dolor sit amet,

问题 I've searched around on how to perform this but I can't find any answer. I'd like to know if my NSTextfield is already truncating the text (... at the end) without having to check the length of its stringValue . I need to do this to know if I should set a tooltip on my NSTextfield (acting like a simple label). The reason I don't want to check the length of my textfield's stringValue it's because there are some characters that occupy more space than others, so that's not very accurate Thanks!

问题 I'm trying to make a multi-line label with 2 lines truncate the last line only. But it seems that, if I choose the Layout of that label as Truncates , my multi-line label becomes one-line. Here's what I want (I manually typed "..." for demonstration purposes): Here's what I have when I set my label as Truncates in IB (as you can see it still has 2 lines but acts as if it was only 1): Is this supposed to happen? If not, how can I achieve the truncate style of the first image? Thanks! 回答1: It

问题 I have following ng-repeat <div class="item-post" ng-repeat="item in items"> <div class="item-content" ng-bind-html="item.text"></div> </div> where item.text is multi-line HTML text and it displays correctly, but I need to truncate it to max-height of item-post div (250px). And then append three dots signalizing that text is longer. I wanted to use jquery.autoellipsis which is working for example on div with static content. For AngularJS I have found angular-ellipsis, but is doesn't work with

问题 I'm using Oracle to synchronize events between two nodes of my application server (never mind why/if that's the best way/etc. This is a given). To do so, I'm using an "events" table that one node (the "active") writes new events to and the other node (the "passive") reads from. The table looks like: Event UUID (UUID) || Event ID (long) || Event Data (several columns of different types) The event ID is a number constantly increasing (application controlled, not a sequence) that signifies the

问题 Is there a jquery truncate plugin that doesn't have trouble with HTML in the content? For instance this plugin does not handle HTML well: http://www.reindel.com/truncate/ 回答1: I'm assuming you've got the most recent version. There's a couple more here which might may help.
