  • How can I prevent Rails from "pluralizing" a column name?

    - by Mike
    I'm using dwilkie's foreigner plugin for rails. I have a table creation statement that looks like: create_table "agents_games", :force => true, :id => false do |t| t.references :agents, :column => :agent_id, :foreign_key => true, :null => false t.references :games, :column => :game_id, :foreign_key => true, :null => false end However, this generates the following SQL: [4;35;1mSQL (2.7ms)[0m [0mCREATE TABLE "agents_games" ("agents_id" integer NOT NULL, "games_id" integer NOT NULL) [0m I want the columns to be called agent_id and game_id - not agents_id and agent_id. How can I prevent Rails from pluralizing the columns? I tried the following in my enviornment.rb file, which didn't help: ActiveSupport::Inflector.inflections do |inflect| inflect.uncountable "agent_id", "game_id" end

  • Validating String Characters as Numeric w/ Pascal (FastReport 4)

    - by user2525015
    I'm new to Pascal and FastReport. This question can probably be answered without knowledge of FastReport. Pascal is Delphi. FastReport4. I have a text box accepting an 8 character string as input. Each character should be numeric. I'm attempting to validate each character as numeric. I've tried using the val function... Procedure Val(S : String; var R: Real; Code : Integer); begin end; procedure thisinputOnChange(Sender: TfrxComponent); var S : String; error : Integer; R : Real; begin S := thisinput.lines.text; Val (S, R, error); If error > 0 then Button2.enabled := False; end; I got this code online. The explanation says that the function will return an error with a code greater than zero if the character cannot be converted to an integer. Is that explanation correct? Am I misinterpreting? Right now I am trying to set a button's enabled property to false if the validation fails. I might change that to a message. For now, I would like to get it to work by setting the button property. I'm not sure if I should be using the onChange event or another event. I'm also not sure if I need to send the input to the val function in a loop. Like I said, I'm just learning how to use this function. I am able to validate the length. This code works... procedure thisinputOnChange(Sender: TfrxComponent); begin if length(thisinput.lines.text) = 8 then Button2.enabled := True; end; Any suggestions? Should I use the val function or something else? Let me know if I need to provide more info. I might not be able to check back until later, though. Thanks for any help.

  • Apache 2 with Weblogic Plug-in Redirection, original location still requested to backend

    - by Edo
    We're trying to setup an SSL server in front of a Weblogic server using Apache as the SSL provider. Here's what's inside of our httpd.conf: <Location /original> SetHandler weblogic-handler WebLogicHost 10.11.1.1 WebLogicPort 8700 PathTrim /original PathPrepend /destination ConnectTimeoutSecs 60 </Location> <Location /destination> SetHandler weblogic-handler WebLogicHost 10.11.1.1 WebLogicPort 8700 ConnectTimeoutSecs 60 </Location> This setup works mostly, but in the ssl_error_log file there're these entries: [Wed Aug 11 14:59:00 2010] [error] [client xxx.xxx.xxx.xxx] ap_proxy: trying GET /original at backend host '10.11.1.1/8700; got exception 'CONNECTION_REFUSED [os error=0, line 1739 of ../nsapi/URL.cpp]: Error connecting to host 10.11.1.1:8700' The weird thing is, the redirection still works, but these annoying entries still shows up. Anyone can point out where did we go wrong? Thanks.

  • Twitter Oauth Strategy with Warden + Devise Authentication Gems for Ruby

    - by Michael Waxman
    Devise, the authentication gem for Ruby based on Warden (another auth gem) does not support Twitter Oauth as an authentication strategy, BUT Warden does. There is a way to use the Warden Twitter Oauth strategy within Devise, but I cannot figure it out. I'm using the following block in the devise config file: config.warden do |manager| manager.oauth(:twitter) do |twitter| twitter.consumer_secret = <SECRET> twitter.consumer_key = <KEY> twitter.options :site => 'http://twitter.com' end manager.default_strategies.unshift :twitter_oauth end But I keep on getting all sorts of error messages. Does anyone know how to make this work? I'm assuming there is more to do here (configuring a new link/route to talk to Warden, maybe adding attributes to the Devise User model, etc.), but I can't figure out what they are. Please help.

  • javascript/php - shorten string to fit into a certain # of lines

    - by Mala
    Hi I have a string that must fit into a box, and must be at most 3 lines long. To shorten it, I plan to truncate it and end it with '...'. I could shorten it to a certain # of characters but if i make it look good with "wwwwwwwww [...] wwww" it won't look right with "iiiiiiiiiii [...] iiii". Is there some way I can shorten it by how much space the string would take up, as opposed to how many characters there are in a string without using a fixed-width font? Ideally I'd like to do this server-side (php) but recognize that actual character width stuff is far more likely to be feasible client-side (JS / jQuery) Mala ps. Please no "simply create an image of '...' and overlay it over the end of the line" hacks or similar - I actually want to shorten the string to the appropriate length

  • Rails validation "failing when succeeding"

    - by Fredrik
    I have this in my user.rb: attr_accessor :old_password def validate unless password.nil? errors.add_to_base("Old password entered incorrect") unless self.valid_password? old_password end end I have old_password as a a virtual attribute that has to be validated as matching with the current before updating to a new password. My problem is that upon correct entering ( password == password confirmation and self.valid_password? old_password ) an error will yield and pass me back to the form. The strange part is that the data will actually be updated in the database, and it will not on wrong input; although it will yield the very same error ("Old password entered incorrect"). What on earth am I doing wrong?

  • Best Linux distro for load-balancers?

    - by Vimvq1987
    I wanted to try HAProxy/Linux Virtual Server like front-end load-balancers, but as far I know, they're Linux-based software. I don't have any experiences with Linux yet. so there're quite many questions to ask: What is the best Linux distro(s) for load-balancing? I plan to use VirtualPC to run some virtual machines. How much RAM is the best for each machine run that distro? I want to simulate a load-balancer with can handle about 100 hits/second, is it possible? Thank you very much!

  • ISerializable and backward compatibility

    hello I have to work an an old application that used binaryFormatter to serialize application data into filestream (say in a file named "data.oldformat") without any optimizazion the main class has been marked with attribute <serializable()>public MainClass ....... end class and the serialization code dim b as new binaryformatter b.serialize(mystream,mymainclass) In an attempt to optimize the serialization/deserialization process I simply made the class implement the ISerializable interface and wrote some optimized serialization routines <serializable()>public MainClass implements ISerializable ....... end class The optimization works really well but I MUST find a way to reatrive the data inside the old files for backward compatibility. How can I do that?? Pierluigi

  • spike in my inverse fourier transform

    - by Jon
    I am trying to compare two data sets in MATLAB. To do this I need to filter the data sets by Fourier transforming the data, filtering it and then inverse Fourier transforming it. When I inverse Fourier transform the data however I get a spike at either end of the red data set (picture shows the first spike), it should be close to zero at the start, like the blue line. I am comparing many data sets and this only happens occasionally. I have three questions about this phenomenon. First, what may be causing it, secondly, how can I remedy it, and third, will it affect the data further along the time series or just at the beginning and end of the time series as it appears to from the picture. Any help would be great thanks.

  • Alignment requirements: converting basic disk to dynamic disk in order to set up software RAID?

    - by 0xC0000022L
    On Windows 7 x64 Professional I am struggling to convert a basic disk to a dynamic one. Under Disk Management in the MMC the conversion is supposed to be initiated automatically, but it doesn't. My guess: because of using third-party partitioning tools there isn't enough space in front and after the partitions (system-reserved/boot + system volume) to store the required meta-data. When demoting a dynamic disk to a basic disk manually, I noticed that some space seems to be required before and after the partitions. What are the exact alignment requirements that allow the on-board tools in Windows to do the conversion?

  • debian modem problems !!!

    - by Raafat
    hay there guys ... I'm a new Debian user, it looks like a very good choice 4 me, every thing is stable, free and easy to use. the problem is, I'm using my modem to establish a dial up connection to the internet (ppp) (a very old stupid way I'm forced to use for now), and using the KPPP application to do that, and nothing is working properly for me. it seems like it didn't recognize my modem or something. i already tried to make a few stuff, and now i know my modem is on /dev/tty0, so i made a link for that on /dev/modem, and query the modem using KPPP and it responded with something like: Ati : Ati0: Ati1: ... ... Ati7: with a textBox to fill up in front of each one of thees Atis, and now, when i press connect on kppp, it says modem ready, and that's it. BTW, my modem is MDC AC'97 any suggestions pleas ....

  • radius traffic accounting - what attributes do I use for traffic (and how)

    - by Mark Regensberg
    we are building a web front end for a internet access token management system that uses radius (freeradius) queried from a captive portal. Reason for building this part is the integration into the accounting and billing platform that operates behind the scenes (all other parts are currently available open source software) The structure is fairly standard, and setting up the basic bits were easy enough (authentication, traffic updates from the captive portal, account expiry date/times) - but I seem to have run out of ability when it comes to limiting an account by traffic consumed. So we can: set up usernames / passwords set expiry dates/times for a given user see the traffic for that user being accurately updated in RADACCT But we can't figure out the correct way/attribute to expire a user when they have consumed X octets of traffic. What attributes are used, or - maybe more accurately - what would be the correct way to use these attributes to limit an account to a certain volume of traffic? Any links to documentation appreciated - freeradius documentation doesn't seem to address the issue directly, or I'm looking in the wrong place... --mark

  • Invalid receiver type 'NSUInteger'

    - by CJ
    I have a Core Data entity whose header file looks like this: @interface MyEntity : NSManagedObject { } @property (nonatomic, retain) NSNumber * index; @end And it's implementation file looks like this: @implementation MyEntity @dynamic index; @end Now, I have a piece of code that looks like this: NSArray* selectedObects = [myEntityArrayController selectedObjects]; NSUInteger theIndex = [[[selectedObects objectAtIndex:0] index] unsignedIntegerValue]; The 'myEntityArrayController' object is a NSArrayController which manages all entities of MyEntity. This code executes correctly, however XCode always gives the warning "Invalid receiver type 'NSUInteger'" for the last line of code. For some reason, XCode thinks that the index method returns a NSUInteger. I'm not sure why it thinks this, because 'objectAtIndex' returns an object of type 'id'. I've cleaned the project several times, and these warnings have hung around for a while. Any suggestions are appreciated.

  • Set focus on textbox after postback.

    I have a search page with 3 TextBoxes that users can filter a search with. I have put the focus on the TextBox that contains text. If more than one contains text just focus on last TextBox. private void SetFocusOnTextBox(ControlCollection ctrlCollection) { foreach (Control ctrl in ctrlCollection) { if (ctrl.GetType() == typeof(TextBox)) { if (((TextBox)ctrl).Text != string.Empty) { SetFocus(ctrl); } } } } After the code runs and a user searches, the focus comes to the beginning of the TextBox, not the end where it would be presumed. How to put insert marked at the end of that TextBox?

  • String.IsNullOrEmpty and Datarow.IsXnull

    - by Jon
    How can I improve this code? What has made this long winded is the fact that I can't use string.IsNullOrEmpty on a data row and instead I have to use a dr.IsHOUSENUMBERNull method AND the string.IsNullOrEmpty to check if it is empty. Why is this? The column in the database is sometimes empty and sometimes NULL. I'm sure this can be written better: If Not dr.IsHOUSENUMBERNull Then If Not String.IsNullOrEmpty(dr.HOUSENUMBER) Then sbAddress.AppendLine(dr.HOUSENUMBER + " " + dr.ADDRESS1) Else sbAddress.AppendLine(dr.ADDRESS1) End If Else sbAddress.AppendLine(dr.ADDRESS1) End If

  • Should I use an ssl terminator or just haproxy?

    - by Justin Meltzer
    I'm trying to figure out how to set up my architecture for a socket.io app that will require both https and wss connections. I've found many tutorials on the web suggesting that you use something like stud or stunnel in front of haproxy, which then routes your unencrypted traffic to your app. If I were to go this route, is it suggested that haproxy and the ssl terminator be on separate instances, or is it fine if they are on the same EC2 server instance? If I do not want to use a separate ssl terminator, could I use haproxy to terminate the ssl? Or instead would it be possible to proxy these https and wss connections to my application and have the node app terminate the ssl itself?

  • Integer in MySQL procedure, syntax error

    - by confiq
    I made simple procedure just to demonstrate CREATE PROCEDURE `demo`(demo_int int) BEGIN DECLARE minid INT; SELECT min(id) FROM (SELECT id FROM events LIMIT demo_int,9999999999999999) as hoo INTO minid; END$$ The problem is with demo_int, if i change it to LIMIT 1,9999999999999999 it works but LIMIT demo_int,9999999999999999 Does not... It gives error You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'demo_int,9999999999999999) as hoo INTO minid; END' at line 4 (errno: 1064) Any clues?
