  • Passing single attributes to associated factories

    - by lambdabutz
    I'm looking for a way to pass fields into the factories of associated models without having to explicitly call the factory itself. For example, lets say I have some factories like so: Factory.define :person do |person| person.name "Default Bob" person.sex "M" person.house {|p| p.association(:house)} end Factory.define :house do |house| house.color "Red" house.has_ac true house.suburb {|h| h.association(:suburb)} end Factory.define :suburb do |suburb| suburb.name "Little boxes" end This is fine and all, but if I want to use factories to create someone in a specific house in a specific suburb I have do this: sub = Factory(:suburb, :name => "Blue town") house = Factory(:house, :color => "Blue", :suburb => sub) person = Factory(:person, :name => "Bill", :house => house) While this isn't bad in this small case, my actual models sometimes have 7 or 8 associations, and when I want to create an object whose associations I only care about a single attribute, the code for this starts to get really heavy. Is there somewhat I can pass attributes to nested Factories without having to recall the Factory itself?

  • sqlite3 date and interval functions

    - by umuthorax
    Hi, I wonder whether sqlite3 supports interval function. The following statement is accepted by PostgreSQL, however sqlite3 failed to parse it; select ... from orders where ... and o_orderdate < date '1995-03-01' + interval '3' month Error: near line 4: near "'1995-03-01'": syntax error Then, I modified the statement a little bit such as; and o_orderdate < date('1995-03-01') + interval '3' month This time the error was; Error: near line 4: near "'3'": syntax error Unfortunately, same trick did not work for the interval function i.e. and o_orderdate < date('1995-03-01') + interval('3' month) or and o_orderdate < date('1995-03-01') + interval('3') month or even and o_orderdate < date('1995-03-01') + interval(3 month) still gave me the syntax error. Maybe sqlite3 does not support interval function or am I missing something in its usage? Thanks a lot

  • Eclipse: How to add an existing source folder?

    - by evilfred
    ARGH Eclipse is SO frustrating I have a directory called c:\RemoteSrc . Under this there are 3 directories which are currently source folders (I think? the icon is an open folder with a little orange grid in it) in my Eclipse project. I have dropped a new directory under c:\RemoteSrc which I also want to add to my project. BUT If I right click on my project and go "Build Path..." - "Link Source" and try to add it it tells me "Folder already exists with a different case". Yes i KNOW that the folder already exists THATS WHY IM TRYING TO ADD IT.

  • CGI, python, and setgid

    - by user331398
    I'm running a compiled python cgi script (using cxfreeze) in Apache. The script, among other things, calls os.setuid(some_uid) os.setgid(some_gid) Obviously some_uid/gid are legal and I set the sticky bit for both user and group, and verified it is indeed set. However on every call i get an error os.setgid(int(self.gid)) OSError: [Errno 1] Operation not permitted As you may notice, setuid() is successful, setgid is not. Which is very weird, at least for me, though I admit I have little experience with permissions in Linux. Any thoughts/ideas are welcome. I'm using apache 2.2.15, python 2.6.5, RHEL 5.4 (kernel 2.6.18) Thank you

  • How can I convert arbitrary strings to CLS-Compliant names?

    - by Brian Hinchey
    Does anyone know of an algorithm (or external library) that I could call to convert an arbitrary string (i.e. outside my control) to be CLS compliant? I am generating a dynamic RDLC (Client Report Definition) for an ASP.Net Report Viewer control and some of the field names need to be based on strings entered by the user. Unfortunately I have little control over the entry of the field names by the client (through a 3rd party CMS). But I am quite flexible around substitutions required to create the compliant string. I have a reactive hack algorithm for now along the lines of: public static string FormatForDynamicRdlc(this string s) { //We need to change this string to be CLS compliant. return s.Replace(Environment.NewLine, string.Empty) .Replace("\t", string.Empty) .Replace(",", string.Empty) .Replace("-", "_") .Replace(" ", "_"); } But I would love something more comprehensive. Any ideas? NOTE: If it is of any help, the algorithm I am using to create the dynamic RDLC is based on the BuildRDLC method found here: http://csharpshooter.blogspot.com/2007/08/revised-dynamic-rdlc-generation.html

  • JavaScript: 2 window.opener.location.href statements with alert() in between not functioning

    - by vastbeyond
    I need to make a little JS app to scroll automatically through a list of URLs. I've chosen to have the functionality in a pop-up, for various reasons. The syntax to change the opening window's URL is: window.opener.location.href = "http://www.example.com"; This works fine with one URL, but if two statements are called, only one is executed. I experimented with an alert statement between two of the above statements, and the alert event made the second statement function properly: window.opener.location.href = "http://www.example1.com"; alert("hello world"); window.opener.location.href = "http://www.example2.com"; Question is: does anyone know how to get the first and second window.opener statements to work, without the intervening alert();? Also, how can I add a pause between the two statements, so that the second executes a couple of seconds after the first? Thanks so much!

  • Which Javascript history back implementation is the best?

    - by Malcolm Frexner
    There are implementations for history.back in Micrososft AJAX and jQuery (http://www.asual.com/jquery/address/). I already have jQuery and asp.net ajax included in my project but I am not sure which implementation of history.back is better. Better for me is: Already used by some large projects Wide browser support Easy to implement Little footprint Does anybody know which one is better? EDIT: Another jquery plugin is http://plugins.jquery.com/project/history It is recommmended in the book JQuery Cookbook. This one worked well so far.

  • How can I integrate graphs and JPEG images with RAVE Reports?

    - by JonDave of the Philippines
    I really love RAVE Reports in creating multiple reports especially with formulas and accounting systems... but recently I am having problems with integrating JPEG Pictures and Graphs with my newly Delphi Language developed Little ERP System. I bought some JPEG Components but it seems problematic. I also experienced some irregularities with my RAVE Reports now. When I run my program then try to preview some reports, it seems to be running fine, but when I close the program, the EXE file is still in the taskbar. I need to ctrl-alt-delete first for me to use Report Previews normally. If I don't, RAVE REPORT ERROR message will appear everytime I click the PRINT button; it says "STREAM READ ERROR" even though I used to "FreeAndNil" to free the memory stream when Report Preview Form closes. When I tried to run the My Applications without previewing RAVE reports, the program closes perfectly. Any suggestions and recommendations will be an enormous help. Thank you.

  • What are your Common Magento Configuration Mistakes?

    - by Alan Storm
    If there's something that everybody hates about Magento it's endlessly configuring your modules before being able to write some code. I'm trying to collect a list of common Magento configuration errors for a future project that's I'm close to launching. I'm looking for specific examples of things like using the wrong naming convention on classnames, forgetting the <class /> wrapper when setting up grouped class names. Little things like that that drive you batty for hours until you realize your error. The more details the better!

  • Guidelines for good webcrawler 'Etiquette'

    - by Harry
    I'm building a search engine (for fun) and it has just struck me that potentially my little project might wreak havok by clicking on ads and all sorts of problems. So what are the guidelines for good webcrawler 'Etiquette'? Things that spring to mind: Observe Robot.txt instructions Limit the number of simultaneous requests to the same domain Don't follow ad links? Stopping the crawler from clicking on ads - This one is particularly on my mind at the moment... how do i stop my bot from 'clicking' on ads? if it is going straight to the url in the ad is it counted as a click?

  • Java: how to name boolean properties

    - by NoozNooz42
    I just had a little surprise in a Webapp, where I'm using EL in .jsp pages. I added a boolean property and scratched my head because I had named a boolean "isDynamic", so I could write this: <c:if test="${page.isDynamic}"> ... </c:if> Which I find easier to read than: <c:if test="${page.dynamic}"> ... </c:if> However the .jsp failed to compile, with the error: javax.el.PropertyNotFoundException: Property 'isDynamic' not found on type com... I turns out my IDE (and it took me some time to notice it), when generating the getter, had generated a method called: isDynamic() instead of: getIsDynamic() Once I manually replaced isDynamic() by getIsDynamic() everything was working fine. So I've got really two questions here: is it bad to start a boolean property's name with "is"? wether it is bad or not, didn't IntelliJ made a mistake here by auto-generating a method named isDynamic instead of getIsDynamic?

  • Django: accessing session variables from within a template?

    - by AP257
    Hi all If I set a session variable in Django, like: request.session["name"] = "name" Is there a way I can access it from within a template, or do I have to retrieve it from within a view, and then pass it to a template? Asking because I have around 10 little session variables that I'd like to access within a template, and passing all 10 from the view to the template could get a bit messy. (I have to use session variables because it's a HttpResponseRedirect, but storing the variables in a database is overkill for my purposes.) So - any way to grab session variables directly within a template?

  • Can a client determine whether the server has accept()'d a unix socket?

    - by Havoc P
    I'm dealing with a buggy server that will sometimes fail to accept() connections (but leaves its listening socket open). This is on Linux with unix domain sockets. Currently the only way to detect this is that after sending a bunch of data, the buffer fills up and blocks, and the server isn't sending any replies. This long-after-the-fact failure mode is hard to distinguish from other bugs - the server could be unresponsive for other reasons. Especially for unix domain sockets it seems the kernel should know whether accept() has occurred; is there any way to find this out? Can the client block until accept() happens somehow, or at least check whether it has? This is just for debugging purposes so it can be a little ugly.

  • How does jQuery store data with .data()?

    - by TK
    I am a little confused how jQuery stores data with .data() functions. Is this something called expando? Or is this using HTML5 Web Storage although I think this is very unlikely? The documentation says: The .data() method allows us to attach data of any type to DOM elements in a way that is safe from circular references and therefore from memory leaks. As I read about expando, it seems to have a rick of memory leak. Unfortunately my skills are not enough to read and understand jQuery code itself, but I want to know how jQuery stores such data by using data(). http://api.jquery.com/data/

  • How do people handle working with Code Names for their projects?

    - by Mark
    Hi All, Recently we started using some code names for several different types of prototype applications all following a theme. This made things a little more fun and was a great idea. The problem is that Im not too sure how people deal with migrating a codebase from "codename" state into version 1.0 state which may have a proper name... not something that a client really shouldnt see :) We are using Visual Studio at the moment, and I can see that you can change the assembly name, but there are references to the namespaces, etc... that would really be a large change to make. Do people both changing things like namespaces before the v1.0 release?

  • What Data structure for Reputation Rules in C# (like stackoverflow)

    - by optician
    I am currently building a system which will have entities that will have scores like reputation etc.. I will have a service that will check for certain rules having been triggered, and will perform certain logic if they are triggered. Previously I have used say an Enum for doing this when I have only had to store an id and a description. public enum ShoppingCratCalculation { PartialCalculation = 1, CompleteCalculation =2 } But in this situation I want to carry more information, such as the modification to reputation, all in one place. I'm essentially asking what data structure would be best suited to storing this information, for each rule in the system. 1. Description = string ("User forgot to write a review") 2. DB id = int (23) 3. Rep score modification = int (-5) Maybe a little class (Rule) with these as properties , and then just a list? Does anyone have any best practice suggestions for this kind of struct?

  • Linq to Entities performance within ASP.NET Development Server

    - by tster
    I've been evaluating linq to entities and linq to SQL for a project. Obviously each has its own advantages and disadvantages which have been discussed plenty of times here. However, One thing I am seeing with L2E is kind of odd. Using L2S, when using the ASP.NET Development Server, the performance is a little slower for my web service calls. I'm looking at 300ms vs. 250 ms. However, when using L2E, when using ASP.NET Dev Server, the performance is awful. I'm talking 1,250 ms vs. 220 ms. I know I should probably just use local IIS for development, but I'm curious if anyone else has seen this, or knows what is causing it.

  • Packaging an application that uses the ImageMagick C API

    - by John Gardeniers
    I've created a little Windows app that uses the ImageMagick C API but have run into a bit of a brick wall. The app works fine and I'm ready to share it with a few others in our organisation but I can't find documentation on distributing such an app without installing ImageMagick on the target machine. Does anyone here have information, or a link to information, that details how to package this up for distribution? What DLLs are required and which one(s) need to registered with Windows? The target users will be on a mix of XP and Win7.

  • Version control for Adobe Flash projects

    - by Guss
    I'm working with a very complex Flash project which is part of a full range of services that we deploy for the use of our clients. For most of our software sources (Java, PHP, Javascript, HTML and a some supporting scripts in other languages) we use subversion for version control and management, so we do the same for our Flash projects, even though we gain little benefits from version controlling that (except being able revert to previous versions) as FLA files are stored as just binaries which we cannot get meaningful diffs from. We're putting as much code as we can into AS files which we can properly manage using subversion, but due to the requirements of our architecture and our deployment strategy (both we cannot change because of our clients needs), we still maintain a large collection of FLA files that we need to manage. I've looked at Adobe Version Cue and while I do not really understand what it does in terms of version control, will moving our Flash projects to hosting on Version Cue will give me better control then I currently get from Subversion? Also - if people can share their experience and suggestions regarding version control of Flash projects, it will be very helpful.

  • IIS url rewrite rewriting all .asp to .html

    - by user335711
    I need to create rules for web.config that will rewrite all requests for files with extension .html to .asp and redirect all .asp requests to .html Example: file_xyz.asp rewrites to file_xyz.html directory1/file_xyz.asp rewrites to directory1/file_xyz.html and file_xyz.html redirects to file_xyz.asp directory1/file_xyz.html redirects to directory1/file_xyz.asp What is the syntax for the rule Is this too broad a rule? If I should need for what ever reason to have a physical file such as file_abc.html how do I exclude it from the redirect rule? I am thinking I should just use ISAPI_Rewrite http://www.isapirewrite.com/ there seems to be a ton of resources out there for rewriting with htaccess and very little online help for using IIS 7 URL rewrite. Any thoughts and/or advice Thanks in advance

  • How to apply images conditionally using entries and categories?

    - by Sergio Acosta
    Using version 2.5.3 of ExpressionEngine, I have a list of products displayed by category, but I need the premium products among this list being featured with a small star image. How do you call conditionally this little stars besides the {title}? At the moment this code shows stars for all products and that is not ideal. <ol class="voices-list"> {exp:channel:entries channel="product" orderby="title" sort="asc" category="2&6" dynamic="no"} <li><a href="{page_url}">{title}<img class="feature_icon medium" src="{root_url}img/audio/smallstar.png" alt="star"></a></li> {/exp:channel:entries} </ol> I need your help, please.

  • Correctly Applying an Open Source License

    - by Johannes Rudolph
    My question consists of multiple points that are inherently related, I apologize for that. I tried splitting it up a little more, but I would keep repeating myself. What exactly is required to apply an open source license to a code base that is my Intellectual Property? A lot of Open Source projects include a full copy of the license somewhere in a root directory but do also have some sort of file header including a license description, disclaimer and a copyright notice. Is that really necessary or does it depend on the license type? If someone else contributes changes to this file, does he need to be named in the copyright notice too?

  • Pull image of rendered HTML from a specific browser

    - by Geo Ego
    I am working on an app that will be able to pull an image of rendered HTML from a specific browser. I would like the user to be able to select a specific browser to render an HTML file in, and capture the rendered output in an image file. I am starting with IE8, and I'm not sure where to begin to get the actual rendered output. I can easily open the file in that browser with Process.Start(), but I don't know how to return the rendered output. I have looked a little bit at sinking events, but I don't understand how that works or if that's the right way to go. I would just like some direction, and perhaps some resources to send me on the right path.

  • Why did Steve Sanderson in his "Pro ASP.NET MVC 2 Framework" book change an example IoC container?

    - by rem
    I like Steve Sanderson's "Pro ASP.NET MVC Framework" book. It helped me a lot. I have been waiting for its new edition and it is ready now, as we can see in this Steve's blog post It is updated a lot taking into account all new features of ASP.NET MVC 2, .NET 4 and Visual Studio 2010. In addition, "SportsStore" tutorial of this edition uses Ninject instead of first edition's Castle Windsor for DI. I wonder, why? Does it mean that Castle Windsor became a little outdated?

  • How does bundler work (in general)?

    - by MAP
    Hello, I'm pretty new to Ruby/Rails but I was taking a look at bundler and was wondering how it works exactly. Do you install a full set of gems like normal gem install XYZand then use the Gemfile to pull a certain subset of those gems for use with a specific application? Or do you not install gems normally anymore and just include them in the Gemfile and then do a bundle install to include them all in a bundle that is then used with your application? Thank you so much for taking the time to answer this, I'm just a little confused on what bundler's functionality is exactly. -- MAP
