    - by Claudiu
    I often have a command that processes one file, and I want to run it on every file in a directory. Is there any built-in way to do this?

  • How to apply query to model if field not filtered

    - by jdog
    I have a range of modules running on generator.yml. In some of those I would like to hide records by default of Status: CLOSED (being the last of a range of Statuses). OF course if the user filters for CLOSED i want to show these records. I thought it would make sense to apply andWhere('status_id=?',Status::CLOSED) in a specific table_method , but how do I access the filters of the module from within the model? Is there a better way to do this?

  • how to make sub-muens line up below their parents in horizontal navbars?

    - by Joel
    Hi folks. I'm just putting together a simple nav bar using something similar to this tutorial: http://www.cssnewbie.com/horizontal-dropdown-menus/ The thing is, that I'd like to have the children lists first item to line up directly below the parent. Right now, they just go wherever I float them. Is there a way to do this without absolute positioning? I'd like to achieve something similar to what these guys have in their top nav bar: http://michaelfranti.com/

  • Twitter api and retweets

    - by Juan Manuel
    I'm trying to get the last tweet from the people I follow using the twitter api (http://api.twitter.com/1/statuses/friends.json&screen_name=[username]), but I noticed that if the user's last tweet is a retweet, the json data does not contain a "status" element. Using the "user timeline" api does not work either, the last tweet is the last non retweeted tweet. Is there a way to get the real last status, even if it's a RT, through the twitter API?

    - by SARAVAN
    Hi, I am working in an ASP.NET mvc application. With regards to URL's I could see the Controller and action names in the address bar when user navigates between pages. Is there a way to hide them, such that the address bar always displays http://mywebsite.com without any action names or controller names suffixing them, or is there any other standard practices? Or is it ok to leave the URL as such which can contain action and controller suffixes?

  • Can I update window.location.hash without having the web page scroll?

    - by Jonathon Watney
    Using JavaScript, is there a way to update window.location.hash without scrolling the web page? I have clickable title elements that toggle the visibility of a div directly beneath them. I want the /foo#bar in the history when clicking titles but don't want the page scrolling about. So when navigating away from /foo#bar I'll be able to use the back button and have the div whose ID is in window.location.hash be visible upon return. Is this behavior possible?
