• capybara selenium and JavaScript Destroy

  - by dorelal

  I am using rails 2.3.5 and this is what I did. I have latest cucumber, cucumber-rails and capybara installed. rails demo cd demo ruby script/generate cucumber --rspec --capybara ruby script/generate feature post title:string body:text published:boolean ruby script/generate scaffold post title:string body:text published:boolean rake db:migrate rake cucumber All the tests are passing. Now I want to test using Javascript. At this time this is how scenario looks like Scenario: Delete post Given the following posts: |title|body|published| |title 1|body 1|false| |title 2|body 2|true| |title 3|body 3|false| |title 4|body 4|true| When I delete the 3rd post Then I should see the following posts: |Title|Body|Published| |title 1|body 1|false| |title 2|body 2|true| |title 4|body 4|true| I added @javascript at the top. Now when I run rake cucumber then I see a confirmation page. But nothing happens until I click. What do I need to do so that OK is clicked automatically and test proceeds ahead.

• HttpWebRequest.GetResponse() - what specific status codes cause an exception to be thrown?

  - by H. Morrow

  I've hunted around for some definitive documentation on this but haven't had much luck finding any. Basically - the question is - for which HTTP Status codes coming back from the server will HttpWebRequest.GetResponse() generate a WebException after doing something like say, a POST? Specifically - will it generate a WebException for anything other than status 200 OK? Or will it only generate a WebException for say, 400, 404, and 500 (for the sake of argument). I want to know since, the server I'm communicating with defines anything other than HTTP 200 OK coming back as an error condition - and the key is, can I rely on a WebException being generated for anything other than 200? (I've currently written my code so that it'll actually check the return status code everytime to ensure it's 200 OK and if it's not, take appropriate action - but it's alot of duplication between that, and the catch block for a WebException, and I'm hoping to clean it up...) Any relevant links to documentation would be most appreciated. Thanks!

• Create pdf from inDesign at runtime...

  - by Lieven Cardoen

  For a project I need to automate creation of business cards. Now, they have a InDesign file for each business card template. They insert the info of alle the people in the indesign file and then generate a pdf of it. Now, entering the information of customers in a web application is no problem, but how will I generate a pdf and how will I alter the indesign file at runtime? I think that altering the indesign file will be not possible programmatically? Could I generate a pdf from the indesign with one card template in it. At runtime I would copy the card in the pdf x number of times. Then I would need to inject the information of the people (name, address, ...)? What's possible here? The final pdf is used by a machine that automatically creates the business cards, cuts them, ...

  - by loviji

  Hello, I would like your advice about how best to solve my problem. In a Web server is running. NET Framework 4.0. Whatever the methods and technologies you would advise me. applications built on the basis Asp.NET MVC 2. I have a database table in MS SQL Server.

• Erlang list comprehension, traversing two lists and excluding values

  - by ErJab

  I need to generate a set of coordinates in Erlang. Given one coordinate, say (x,y) I need to generate (x-1, y-1), (x-1, y), (x-1, y+1), (x, y-1), (x, y+1), (x+1, y-1), (x+1, y), (x+1, y+1). Basically all surrounding coordinates EXCEPT the middle coordinate (x,y). To generate all the nine coordinates, I do this currently: [{X,Y} || X<-lists:seq(X-1,X+1), Y<-lists:seq(Y-1,Y+1)] But this generates all the values, including (X,Y). How do I exclude (X,Y) from the list using filters in the list comprehension?

• Creating a web-service client directly from the source

  - by ben

  Hi, I am trying to generate the WS client jar directly from the @Webservice class(es). Let's take this example : package com.example.maven.jaxws.helloservice; import javax.jws.WebService; @WebService public class Hello { public String sayHello(String param) { ; return "Hello " + param; } } I can generate a war file and use glassfish to serve this webservice, and from there I can use the glassfish WSDL URL to generate the client sources. What I am trying to do is to skip the glassfish part. From my maven project defining the webservice, I would like to use the jaxws-maven-plugin to create the client classes but I cannot find any way to specify the actual URL of the webservice. It should be possible right? @see also http://stackoverflow.com/questions/2097789/creating-a-web-service-client-with-a-known-but-inaccessible-wsdl

• Problem with Apache Commons Id UUID Version 1 generation

  - by Pekka Mattila

  My problem is to generate version 1 UUIDs. We use Jetty 6.x, Maven (to start Jetty among other things) and Apache Commons ID (to generate UUID version 1 from the current time). Apache Commons ID requires a configuration file that is told to the JVM, using a parameter, e.g. 'org.apache.commons.id.uuid.config.resource.filename=commons-id-uuid.xml'. I checked the Apache Commons ID code and it tries to find the file from the classpath. Jetty's documentation states that WEB-INF/lib and WEB-INF/classes are in the classpath. The 'commons-id-uuid.xml' can be found from the deployed war file from the root of WEB-INF/classes directory but Jetty cannot load it: Message: java.lang.RuntimeException: java.lang.IllegalStateException: commons-id-uuid.xml loaded as system resource is null Jetty was started using the following command: mvn jetty:run -Dorg.apache.commons.id.uuid.config.resource.filename=commons-id-uuid.xml Any idea what is going wrong? We just need to generate UUID version 1 identifiers. Any suggestions?

• What is a good Visio Enterprise Architect replacement?

  - by MattValerio

  I've been using Visio 2002/2003 Enterprise Architect to do my database schema design visually and then forward-generate the DDL to create the database. I wanted to switch to Visio 2007, but while it does have database diagramming support, it doesn't have the ability to generate DDL. Bummer. I am really disappointed because it seems like Microsoft has completely abandoned this feature. You can't do it in Visual Studio (that I've found). You can sorta do it with SQL Server Management Studio if you insert database diagrams into your database, but any edits to the schema immediately take effect. Has anyone found a good program to do this? I'm hoping to find one that is free and can generate DDL/SQL for SQL Server.

• url template tag in django template

  guys: I was trying to use the url template tag in django, but no lucky, I defined my urls.py like this urlpatterns = patterns('', url(r'^analyse/$', views.home, name="home"), url(r'^analyse/index.html', views.index, name="index"), url(r'^analyse/setup.html', views.setup, name="setup"), url(r'^analyse/show.html', views.show, name="show"), url(r'^analyse/generate.html', views.generate, name="generate"), I defined the url pattern in my view like this {% url 'show'%} then I got this error message Caught an exception while rendering: Reverse for ''show'' with arguments '()' and keyword arguments '{}' not found.

• Setting up gcov in Xcode 3.1

  - by Algorithmic

  I'm trying to setup my Xcode project to be instrumented with gcov so I can determine the code coverage of my unit tests. All of the documentation I find online talks about settings that I don't find in Xcode 3.1, though. An example: To work with Coverstory, first you need to set up your target to work with gcov. This requires turning on "Instrument Program Flow", "Generate Test Coverage Files" and linking with the gcov library. (Using Coverstory) The closest thing I can find to "Instrument Program Flow" and "Generate Test Coverage Files" in my build settings is "Generate Profiling Code", which doesn't appear to do what I want it to do. Am I looking in the wrong place for these settings or are all of the examples I'm finding online stale?

  I am trying to make my own Labeller plugin for Cruise Control .Net 1.4.3.

• Using hash functions with Bloom filters

  - by dangerstat

  Hi, A bloom filter uses a hash function (or many) to generate a value between 0 and m given an input string X. My question is how to you use a hash function to generate a value in this way, for example an MD5 hash is typically represented by a 32 length hex string, how would I use an MD5 hashing algorithm to generate a value between 0 and m where I can specify m? I'm using Java at the moment so an example of to do this with the MessageDigest functionality it offers would be great, though just a generic description of how to do about it would be fine too. Thanks

• How to organize asp.net mvc project (using entity framework) and a corresponding database project?

  - by Bernie

  I recently switched to vs2010 and am experimenting with asp.net MVC2. I am building a simple website and use the entity framework to design the data model. From the .edmx file, I generate the database tables. After a few iterations, I decided that it would be nice to have version control of the database schema as well, and therefore I added a database project into which I imported the script that is generated from the datamodel. As a result, I have to generate the sql every time that I change the model and redo the import. The database project automatically updates the database. Although the manual steps to generate the sql and the import are annoying, this works pretty well, until I wanted to add the standard tables for user accounts/authorization etc. I can use the framework tools to add the necessary tables, views etc. to the database, but as I do not want to have them in the .edmx model I end up with a third manual step. Is anybody facing similar issues?

• How to set response header in JAX-RS so that user sees download popup for Excel?

  - by masato-san

  I wrote code that generate Excel file using REST JAX-RS and I confirmed that the generated Excel file is in GlassFish server directory. But my goal is when user click on the button (which generate Excel .xls), I want download popup to show up asking user whether to save or open the .xls file just like any other web services doing for downloading any type of files. According to my search, the step is: generate Excel .xls (DONE) write the excel to stream in JAX-RS file, set response header to something like, String fileName = "Blah_Report.xls"; response.setHeader("Content-Disposition", "attachment; filename=" + fileName); My question is I'm doing all of this in JAX-RS file and I don't have HttpServletResponse object available. According to the answer from Add Response Header to JAX-RS Webservice He says: You can inject a reference to the actual HttpServletResponse via the @Context annotation in your webservice and use addHeader() etc. to add your header. I can't really figure what exactly that means without sample code..

• Xcode Tips for Eclipse users?

  - by willcodejavaforfood

  Hi, I've been slowly working my way through the examples in Beginning iPhone Development and there are a few things that I have not been able to figure out, but I'm sure you guys can help me with it. In Eclipse there is a Source-Generate Getters/Setters, can you do something similar to synthesize properties in Xcode I also cannot seem to find a Refactor menu I'm also struggling to find the equivalent to Source-Override/Implement Methods --Edit-- I failed to describe my problem it seems. I do know that synthesizing properties will generate getters/setters for me, but I am looking for a way to generate the @property/@synthesize code, by selecting the variables. Short list to start with, but I will probably have more as my confusion grows in might. :)

• Vb.exe performance time

  - by vinodacharyabva

  Hi I am running a vb.exe through automation. In exe I have return a code which takes a data from database and saves that data into file. I ran that .exe for the first time. It took 1 mins. For testing baseline I called same .exe 5 times one after the other. But it took nearly 10 mins to generate. My question is if it takes 1 min for 1 report to generate then it should take 5 mins to generate 5 report but why it is taking 10 mins (more than the double). Is there any problem while calling a exe one after the other?

• Using Ruby on Rails, can a polymorphic database be created in a few steps (with polymorphic associat

  - by Jian Lin

  I thought it could be created in a few steps but it can't yet: rails poly cd poly ruby script/generate scaffold animal name:string obj_type:string obj_id:integer rake:migrate ruby script/generate scaffold human name:string passportNumber:string rake:migrate ruby script/generate scaffold dog name:string registrationNumber:string rake:migrate and now change app/models/animal.rb to: class Animal < ActiveRecord::Base belongs_to :obj, :polymorphic => true end and run ruby script/server and go to http://localhost:3000 I thought on the server then if I create an Michael, Human, J123456 and then Woofie, Dog, L23456 then the database will have entries in the Dogs table and "Humen" or "Humans" table as well as in the Animals table? But only the Animals table has records, Dogs and "Humen" do not for some reason. Is there some steps missing?

• Repeating a List in Scala

  - by Ralph

  I am a Scala noob. I have decided to write a spider solitaire solver as a first exercise to learn the language and functional programming in general. I would like to generate a randomly shuffled deck of cards containing 1, 2, or 4 suits. Here is what I came up with: val numberOfSuits = 1 (List["clubs", "diamonds", "hearts", "spades"].take(numberOfSuits) * 4).take(4) which should return List["clubs", "clubs", "clubs", "clubs"] List["clubs", "diamonds", "clubs", "diamonds"] List["clubs", "diamonds", "hearts", "spades"] depending on the value of numberOfSuits, except there is no List "multiply" operation that I can find. Did I miss it? Is there a better way to generate the complete deck before shuffling? BTW, I plan on using an Enumeration for the suits, but it was easier to type my question with strings. I will take the List generated above and using a for comprehension, iterate over the suits and a similar List of card "ranks" to generate a complete deck.

• Oracle sequence but then in MS SQL Server

  - by Raymond

  In Oracle there is a mechanism to generate sequence numbers e.g.; CREATE SEQUENCE supplier_seq MINVALUE 1 MAXVALUE 999999999999999999999999999 START WITH 1 INCREMENT BY 1 CACHE 20; And then execute the statement supplier_seq.nextval to retrieve the next sequence number. How would you create the same functionality in MS SQL Server ? Edit: I'm not looking for ways to automaticly generate keys for table records. I need to generate a unique value that I can use as an (logical) ID for a process. So I need the exact functionality that Oracle provides.

• Seam-gen isn't working properly.. log4j acuses an error

  Hello Seam Users, I'm having a couple problems with my Seam start up. I did the ./seam generate to reverse my current postgres db, which contains 4 tables, first I though everything was okay, just a warning message, but when I imported the project into eclipse, I saw that none of my packages had any class. This is the error that seam generate, got me.

• EF 4.x generated entity classes (POCO) and Map files

  - by JBeckton

  I have an MVC 4 app that I am working on and using the code first implementation except I cheated a bit and created my database first then generated my entity classes (poco) from my database using the EF power tools (reverse engineer). I guess you can say I did database first method but I have no edmx file just the context class and my entity classes (poco) I have a few projects in the works using MVC and EF with pocos but just the one project I used the tool to generate my pocos from the database. My question is about the mapping files that get created when I generate my pocos using the tool. What is the purpose of these Map files? I figured the map files are needed when generating the db from the model like with the true code first method, in my case where I am using a tool to generate my model from the database do the map files have any influence on how my app uses the entity classes?
