  • scope equivalent in rails 2.3.x?

    - by Jacob Relkin
    Is there a way to generate a group of routes under an admin scope without having to create a new physical directory (like namespace requires you to). I know that in Rails 3 there is a scope method on the route mapper, and this appears to do what I want, but apparently it doesn't exist in Rails 2.3.x My goal is to have a route like this: "/admin/products" map to "app/controllers/products_controller, not "app/controllers/admin/products_controller". Is there any way to accomplish this in Rails 2.3.x?

  • rails - named scoped help

    - by sameera207
    Hi All, I want to write a named scoped to get a record from its id. Ex: I have a model called Event and its same as doing Event.find(id) (I dont want to use find inside my controller and I want my controller to use a named scoped (for future flexibility)) So I have written a named scoped named_scope :from_id, lambda { |id| {:conditions = ['id= ?', id] } } and I'm calling it from my controller like Event.from_id(id) But my problems is it returns Event object array not only one object Ex: if I want to get event name I have to write event = Event.from_id(id) event[0].name instead I want to write event = Event.from_id(id) event.name Am I doing something wrong here.. thanks in advance cheers sameera

  • Scala regex Named Capturing Groups

    - by Brent
    In scala.util.matching.Regex trait MatchData I see that there support for groupnames (Named Capturing Groups) But since Java does not support groupnames until version 7 as I understand it, Scala version 2.8.0.RC4 (Java HotSpot(TM) 64-Bit Server VM, Java 1.6. gives me this exception: scala> val pattern = """(?<login>\w+) (?<id>\d+)""".r java.util.regex.PatternSyntaxException: Look-behind group does not have an obvio us maximum length near index 11 (?<login>\w+) (?<id>\d+) ^ at java.util.regex.Pattern.error(Pattern.java:1713) at java.util.regex.Pattern.group0(Pattern.java:2488) at java.util.regex.Pattern.sequence(Pattern.java:1806) at java.util.regex.Pattern.expr(Pattern.java:1752) at java.util.regex.Pattern.compile(Pattern.java:1460) So the question is Named Capturing Groups supported in Scala? If so any examples out there? If not I might look into the Named-Regexp lib from clement.denis.

  • using ‘using’ and scope. Not try finally!

    - by Edward Boyle
    An object that implements IDisposable has, you guessed it, a Dispose() method. In the code you write you should both declare and instantiate any object that implements IDisposable with the using statement. The using statement allows you to set the scope of an object and when your code exits that scope, the object will be disposed of. Note that when an exception occurs, this will pull your code out of scope, so it still forces a Dispose() using (mObject o = new mObject()) { // do stuff } //<- out of Scope, object is disposed. // Note that you can also use multiple objects using // the using statement if of the same type: using (mObject o = new mObject(), o2 = new mObject(), o3 = new mObject()) { // do stuff } //<- out of Scope, objects are disposed. What about try{ }finally{}? It is not needed when you use the using statement. Additionally, using is preferred, Microsoft’s own documents put it this way: As a rule, when you use an IDisposable object, you should declare and instantiate it in a using statement. When I started out in .NET I had a very bad habit of not using the using statement. As a result I ran into what many developers do: #region BAD CODE - DO NOT DO try { mObject o = new mObject(); //do stuff } finally { o.Dispose(); // error - o is out of scope, no such object. } // and here is what I find on blogs all over the place as a solution // pox upon them for creating bad habits. mObject o = new mObject(); try { //do stuff } finally { o.Dispose(); } #endregion So when should I use the using statement? Very simple rule, if an object implements IDisposable, use it. This of course does not apply if the object is going to be used as a global object outside of a method. If that is the case, don’t forget to dispose of the object in code somewhere. It should be made clear that using the try{}finally{} code block is not going to break your code, nor cause memory leaks. It is perfectly acceptable coding practice, just not best coding practice in C#. This is how VB.NET developers must code, as there is no using equivalent for them to use.

  • named-checkzone reports 'ns.example.com.ns' has no address records (A or AAAA)

    - by hydroparadise
    The first thing I see wrong is that its a recursion problem. But I'm not sure where the problems lie in my reverse lookup file. ns should report back as ns.example.com but instead getting ns.example.com.ns. Of course it wouldn't find any entries for that name because there isn't one, nor is it supposed to. Here's my reverse file: $TTL 86400 @ IN SOA ns.example.com root.example.com. ( 16071990 ; Serial 3600 ; Refresh 1800 ; Retry 604800 ; Expire 86400 ; Minimum TTL ) @ IN NS ns.example.com It's not extraordinarily complicated. What my question is, what other files affect the output for named-checkzone when checking a name against the revers file?

  • Can't connect to sql server 2008 named instance

    - by hcsrpm
    I have sql server 2005 and 2008 running on a server on my local (and very straightforward) network. Using sql management studio 2008 and visual studio 2008, I can connect over the network to the 2005 instance which is the default instance. I can't connect to the 08 instance (named MC08). I can connect to both when logged in to the server. Remote connections have been enabled for MC08 and dynamic ports is turned off (assigned to port 1045). The sql browser service is running as well. This used to work so I'm not sure what has changed. I can't connect using the IP address either. Nothing unusual in the event log either. Any ideas?

  • Need help using a super scope

    - by Vdub
    I have a windows server 2008 r2 standard running our DCHP, DNS, and AD. also I have (3) HP Pro Curve 2510-G switches (J9280A). Right now our LAN is set up 192.168.50.2-192.168.50.254 on our sub-net (A) and another scope with 192.168.51.2-192.168.51.254 sub-net (B) both have sub-net mask of 255.255.255.0. The same server is our DNS which is 192.168.50.242 and our firewall (watchguard) is the gateway at 192.168.50.1. Right now the sub-net (B) does not have DHCP active so only sub-net (A) is giving a pool. My problem is that we are trying to have open WiFi on our network and i am assuming that i can use the sub-net (B) for that if i activate it and use sub-net (A) for our staff only. I have noticed that when i set up a static on a client pc and set it to 192.168.51.x i cannot use the DNS of 192.168.50.242 however i can use 8.8.8.8 and it works fine, i am guessing that because it is on a different sub-net? Forgive me as i am very new at this and dont know a lot. Is there easy way with the equipment i have to a accommodate wifi for hundreds of people without causing problems for our staff? (multiple same IP address assigns) I appreciate any and all info!

  • DNS Zone file and virtual host question (repost because my question got moved and now I can't comment on the original for some reason)

    - by Jake
    Sorry this is a repost, the original question got moved to here form stack overflow and for some reason I can't comment or respond to answers on that one anymore. Hi all, I'm trying to set up a virtual host for redmine.SITENAME.com. I've edited the httpd.conf file and now I'm trying to edit my DNS settings. However, I'm not sure exactly what to do. Here's an snippet of what's already in the named.conf file (the file was made by someone else who is unreachable): zone "SITENAME.com" { type master; file "SITENAME.com"; allow-transfer { ip.address.here.00; common-allow-transfer; }; }; I figure if I want to get redmine.SITENAME.com working, I need to copy that entry and just replace SITENAME.com with redmine.SITENAME.com but will that work? I was under the impression I needed a .db file but I don't see any reference to one in the current named.conf file. I also don't see any .db files or files named SITENAME in named.conf's directory. Any ideas where these illusive pre-existing db files could be?

  • Windows Not Honoring DHCP Scope

    - by jerhinesmith
    Please bear with me as I'm not a networking person by trade. Our current configuration at work includes two Windows Servers serving as DHCP/Active Directory servers (if that makes sense) -- one replicating from the other. On both machines, the DNS resolution is set up as: Main Windows Box (10...* address) Public IP Address (for Verizon) Public IP Address (secondary Verizon) Secondary Windows Box (10...* address) Assuming our domain is foo.com, we maintain the foo.com website on a hosted VPS with it's own IP address. The problem is that even though bar.foo.com is an internal server and is defined in DNS on the Primary Windows machine, when I ping bar or even bar.foo.com it resolves to the hosted IP address instead of the 10.* address. I tried taking both of the Public IP addresses out of the DHCP scope, and that seemed to work, but it completely slowed down access to any external sites, so that wasn't acceptable. I also tried adding the two Windows machine as the DNS servers on my desktop. That too worked, but I'd rather not have everything enter their DNS servers, as the above setup should theoretically be working. Is there anything I could check to see why pinging bar.foo.com isn't resolving to the DNS entry on the Windows machines? Here's a summary of the ping results, if they help: Pinging from servers with static IP bar.foo.com resolves with correct IP address Pinging from linux machines not joined to the domain bar.foo.com resolves with correct IP address Pinging from user's desktop machines, joined to the domain, but dynamic IP bar.foo.com resolves with incorrect IP address This is driving me crazy!

  • PHP Preserve scope when calling a function

    - by Joshua
    I have a function that includes a file based on the string that gets passed to it i.e. the action variable from the query string. I use this for filtering purposes etc so people can't include files they shouldn't be able to and if the file doesn't exist a default file is loaded instead. The problem is that when the function runs and includes the file scope, is lost because the include ran inside a function. This becomes a problem because I use a global configuration file, then I use specific configuration files for each module on the site. The way I'm doing it at the moment is defining the variables I want to be able to use as global and then adding them into the top of the filtering function. Is there any easier way to do this, i.e. by preserving scope when a function call is made or is there such a thing as PHP macros? Edit: Would it be better to use extract($_GLOBALS); inside my function call instead? Edit 2: For anyone that cared. I realised I was over thinking the problem altogether and that instead of using a function I should just use an include, duh! That way I can keep my scope and have my cake too.

  • Yii 'limit' on related model's scope

    - by pethee
    I have a model called Guesses that has_many Comments. I'm making eager queries to this to then pass on as JSON as response to an API call. The relations are obviously set between the two models and they are correct(one2many <= belongs2) I added a scope to Comments called 'api' like this: public function scopes() { return array( 'api' => array( 'select' => 'id, comment, date', 'limit'=>3, 'order'=>'date DESC', 'together'=>true, ), ); } And I'm running the following one-liner query: $data = Guesses::model()->with('comments:api')->findAll(); The issue here is that when calling the 'api' scope using a with('relation'), the limit property simply doesn't apply. I added the 'together'=true there for another type of scope, plus I hear it might help. It doesn't make a difference. I don't need all the comments of all Guesses. I want the top 3 (or 5). I am also trying to keep the one-liner call intact and simple, manage everything through scopes, relations and parameterized functions so that the API call itself is clean and simple. Any advice?

  • Fedora 13 - No module named yum

    - by drozzy
    This is driving me bananas! After a recent update in Fedora 13 64bit, my yum is gone: $> yum update There was a problem importing one of the Python modules required to run yum. The error leading to this problem was: No module named yum Please install a package which provides this module, or verify that the module is installed correctly. I tried looking for an RPM yum package - to install yum. I went to the Fedora site: http://fedoraproject.org/wiki/Tools/yum Call me blind but I cannot find it anywhere on that page! Most of the solutions suggest repairing yum... with yum! But I don't have yum? Yum yum yum? :< Any help? Here are some outputs for rpm commands: $> rpm -ql python | grep "site-packages$" /usr/lib/python2.6/site-packages /usr/lib64/python2.6/site-packages $> rpm -ql yum | grep "site-packages/yum$" /usr/lib/python2.6/site-packages/yum

  • Using bind (named) as a public proxy server

    - by TrentDavis
    We have a Python DNS server that does a bunch of stuff to figure out values it should return for various DNS records. This works nicely, however as it is Python, the performance under high load won't be great. What I would like to do is have a "proxy" bind server sit in front of it to return results to the public internet. This will cache the results (typically 15 minutes, some records are a few seconds), so the load on the Python server will be greatly reduced as it will only see one look up per domain (only about 100 domains) every 15 minutes. The data in these domains changes a lot, so using a master won't work as it will constantly be changing. I have something setup that looked like it would work great (using a forwarder for the zone), and tested it with dig etc, all going great. However when we went to go live with it, things weren't working, and we figured out that named is not setting the "Authoritative" bit (fair enough, it is a forwarder). So my question is, can we tell bind to set the Authoritative bit for forwarded domains? I have looked at all the doco I can find, and can't find anything about doing things this way. Most of the doco about using it as a proxy if for a LAN to the internet. Ideally I would like to use bind as it is there and installed (CentOS 5 servers). But at a pinch we could look at a different name server to do the work if it just can't be done with bind. Thanks.

  • "ImportError: No module named flask" - Trouble with nginx + uWSGI + Flask in a virtualenv setup

  • Excel 2007: Named ranges problems when linking workbooks

    - by Mike
    I've 30+ workbooks each with 5 specific worksheets (formated the same). Each worksheet's data needs to be linked to a master workbook, so that I end up with 5 master workbooks and all the specific data in one long table format $A$2:$I$750. (Are you still with me? ;)) I don't have access to a database, so I'm having to link the sheets to their master workbook directly. I've highlighted the data I need; named the range; and then tried referencing this from my master workbook. I get the #Value error symbol when I try to link (=[WorkbookName]!MyNamedRange) to a cell that doesn't match the top left cell of my range. Example: MyNamedrange is always =$A$2:$I43$ on one specific sheet. On my master workbook it works if it's referenced at A2 but I get #Value if it's referenced A1, or A44. Any ideas? I'm trying to link my data in one continous table so I can run a pivot on it, and other things. Can it be done like this, or should I just copy and paste? I'm trying to keep things 'linked'so I do not need to spend time C&Ping all day. Many thanks Mike.

  • Apache Named Virtual Hosts and HTTPS

    - by Freddie Witherden
    I have an SSL certificate which is valid for multiple (sub-) domains. In Apache I have configured this as follows: In /etc/apache2/apache2.conf NameVirtualHost <my ip>:443 Then for one named virtual host I have <VirtualHost <my ip>:443> ServerName ... SSLEngine on SSLCertificateFile ... SSLCertificateKeyFile ... SSLCertificateChainFile ... SSLCACertificateFile ... </VirtualHost> Finally, for every other site I want to be accessible over HTTPS I just have a <VirtualHost <my ip>:443> ServerName ... </VirtualHost> The good news is that it works. However, when I start Apache I get warning messages [warn] Init: SSL server IP/port conflict: Domain A:443 (...) vs. Domain B:443 (...) [warn] Init: SSL server IP/port conflict: Domain C:443 (...) vs. Domain B:443 (...) [warn] Init: You should not use name-based virtual hosts in conjunction with SSL!! So, my question is: how should I be configuring this? Clearly from the warning messages I am doing something wrong (although it does work!), however, the above configuration was the only one I could get to work. It is somewhat annoying as the configuration files have an explicit dependence on my IP address.
