问题 How to call jar file (a java archive file) from ruby class. And access the functions/methods from it. I am refering the following link But I am getting the following error: 'require': cannot load such file -- /tmp/Test.jar (LoadError) How can I resolve this issue. 回答1: You can use a system call.

问题 I'm sure I miss some basic thing. I had a correctly working app in dev environment. Than I had some modifications that I cant correctly explain (with the migrations and tried to insert seed_dump gem). Now every rake command drops an error: C:\Programozas\Rails Apps\sorsveto>rake about rake aborted! undefined method `active_record' for #<Rails::Application::Configuration:0x3e482 98> Tasks: TOP => about => environment (See full trace by running task with --trace) or C:\Programozas\Rails Apps

But after successful deployment I get error: ThinkingSphinx::SphinxError (unknown local index 'user_core' in search request): I try rebuild, restart, and other things, but it doesn't

In gmaps4rails, how do I move the map so the marker is in view?

由 拟墨画扇 提交于 2020-01-15 10:42:55
问题 I have a set of locations that I want to bring up, individually through ajax calls, and some of them aren't within the current bounds of the map. Is there a way to move the map so the marker is in view? I don't need it to be in the center, just as long as it's in view. 回答1: I figured it out after some research. I'd still be curious to know how to NOT have to center if the marker is visible on the map. var centerpoint = new google.maps.LatLng(lat_value, long_value); Gmaps4Rails.map.setCenter

由 此生再无相见时 提交于 2020-01-15 08:38:32
问题 I have an angular app <html ng-app='sampApp'> </html> I have an anchor link inside the app. <a href='/user/profile'>Redirect here</a> But the page is not getting reloaded on clicking the anchor tag. It just makes an ajax call to render the page. 回答1: Standard url used in angular start with #, unless you are using html5 model, so the anchor should be <a href='#/user/profile'>Redirect here</a> If you want to do full page refresh or page redirect, then you need to stop Angular from intercepting
