How do I save an array of obects into the database? For now I am doing for a in array a.save end. I am sure there must be an easy way to do this. -- Posted via http://www.ruby-forum.com/.

I want to programmatically under certain conditions return a 404 (page not found) error to the browser. How can I do this from my controller? I''m assuming I need to set a header on the reponse obect. However I can''t figure out what the header name is. thanks, scott. -- Posted via http://www.ruby-forum.com/.

I''ve been trying to use the prototype.js Ajax obect''s event handlers (onCreate, onComplete) inside the options tags as below: function updateCalendar(today, id){ new Ajax.Updater("calendars", "calendar.inc.php", {asynchronous: true, onCreate: function(){ showBusy }, onComplete: function(){ hideBusy }...

...oro/ > read only = no > include = /etc/samba/cestino.conf > > cestino.conf > vfs objects = recycle I have removed most of the lines from your fileservers smb.conf, leaving only what I believe to be the relevant lines. You initial use vfs_acl_xattr in global, but your 'vfs obects' line in your 'include' file seems to turn it off again, try: vfs objects = recycle acl_xattr in your 'include' file. Rowland

...using not a single time series, but several of them: each time series should be seen as one "independent" realisation of the mAr process; for instance this happens when you have a time series with lacking data (holes) : if I have two time series and a hiatus in the middle, I would like my obective function in the calibration to be the sum of the two classical objective function, one for each continuous time series. Is there a function in R that could do this type of estimation? Or is there a nice way to do that by modifying the objective function within the mAr.est function (I tried but t...

Hi I've set up a domain with 2 dc (samba 4.16.10 - debian 11) a fileserver ( 4.15.13 ubuntu 22) , and 50 windows client. fileserver has a few share with win ACL ( I follow [ https://wiki.samba.org/index.php/Setting_up_a_Share_Using_Windows_ACLs | https://wiki.samba.org/index.php/Setting_up_a_Share_Using_Windows_ACLs ] ) . Everythings works fine and I can setup security access for that

I am trying to create a null object in my application. I would like to assigned a null user object for anonymous/ mot-logged-in user, i.e. if session variable has nil data. In my User model, I have created a subclass like this: class UnassignedUser < User def save false end def update false end def username "Unassigned" end def county_id

hi, I recently attended one of the ruby meetings that we have in my city. There one of the speaker said that google,amazon .. are working on RoR but still the performance of RoR is not at par with J2EE others.... he meant that though google,amazon working o it they will not bring it as front applications only parts the reason ruby is slow in comparison to other languages.... and in real time
