  • How do I... truncate string in an array

    - by ander163
    In a ruby on rails app, I build an array of Project Names and project id values, but want to truncate the length of the names. Current code is: names = active_projects.collect {|proj| [proj.name, proj.id]} I have tried to add a truncate function to the block, but am getting undefined method for class error. Thanks in advance - I just cannot wrap my head around this yet.

  • How to do a Postgresql subquery in select clause with join in from clause like SQL Server?

    - by Ricardo
    I am trying to write the following query on postgresql: select name, author_id, count(1), (select count(1) from names as n2 where n2.id = n1.id and t2.author_id = t1.author_id ) from names as n1 group by name, author_id This would certainly work on Microsft SQL Server but it does not at all on postegresql. I read its documentation a bit and it seems I could rewrite it as: select name, author_id, count(1), total from names as n1, (select count(1) as total from names as n2 where n2.id = n1.id and n2.author_id = t1.author_id ) as total group by name, author_id But that returns the following error on postegresql: "subquery in FROM cannot refer to other relations of same query level". So I'm stuck. Does anyone know how I can achieve that? Thanks

  • Visual studio ORM designer option

    - by stackoverflowuser
    linq to sql visual studio Object-Relational designer generates C# entity class names same as the table names (except pluralizing it). so if the table name is authors it generates entity class with name "author". If the table name is Customers it generates class with name "Customer". Is there any option that can be set to make the designer generate entity class names as pascal cased. I am using VS 2010 if that makes any difference. Thanks.

  • Aiming Netbeans code snippets

    - by rwallace
    Not quite sure whether I'm using the right terminology here, but Netbeans has a very nice feature where e.g. if you start typing for it will offer to write a code fragment looping over an array or list, basing it on the name and type of an array or list variable actually in scope. If more than one such variable is in scope it will guess, sometimes correctly and sometimes not. Is there a way to aim this feature at the correct array/list variable?

  • Working with Decimal fields in SSIS

    - by CoffeeAddict
    I'm using SQL Server 2008 w/SP2. I've got an incoming decimal(9,2) field incoming through my OLE DB transformation to my recordset destination transformation. It's like it's reading it as something other than a decimal? I don't know..I'm not an SSIS guru. So continuing on...the problem I have starts here with me trying to stuff the value into a variable for this decimal field. In a foreach loop, I have a variable to represent this decimal field so I can work with it. The first problem that I believe is pretty well known is SSIS variables do not have a decimal type. And from my own testing and what I've read out there, people are using type object for the variable to make SSIS "happy" with decimal values? It makes mine happy. But, then in my foreach loop, I have a for loop. And inside that I'm using an E*xecute SQL Task transformation*. In it, I need to create a parameter mapping to my variable so I can work with that decimal field in my T-SQL call in here. So now I see a type decimal for the parameter and use it and set that to point to my variable. When I run SSIS and it hits my SQL call, I get this in my output window.: The type is not supported.DBTYPE_DECIMAL So I am hitting a wall here. All I wanna do is work with a decimal!!!

  • R ggplot barplot; Fill based on two separate variables

    - by user1476968
    A picture says more than a thousand words. As you can see, my fill is based on the variable variable. Within each bar there is however multiple data entities (black borders) since the discrete variable complexity make them unique. What I am trying to find is something that makes each section of the bar more distinguishable than the current look. Preferable would be if it was something like shading. Here's an example (not the same dataset, since the original was imported): dat <- read.table(text = "Complexity Method Sens Spec MMC 1 L Alpha 50 20 10 2 M Alpha 40 30 80 3 H Alpha 10 10 5 4 L Beta 70 50 60 5 M Beta 49 10 80 6 H Beta 90 17 48 7 L Gamma 19 5 93 8 M Gamma 18 39 4 9 H Gamma 10 84 74", sep = "", header=T) library(ggplot2) library(reshape) short.m <- melt(dat) ggplot(short.m, aes(x=Method, y= value/100 , fill=variable)) + geom_bar(stat="identity",position="dodge", colour="black") + coord_flip()

  • Contextual bindings with Ninject 2.0

    - by Przemaas
    In Ninject 1.0 I had following binding definitions: Bind<ITarget>().To<Target1>().Only(When.Context.Variable("variable").EqualTo(true)); Bind<ITarget>().To<Target2>(); Given such bindings I had calls: ITarget target = kernel.Get<ITarget>(With.Parameters.ContextVariable("variable", true)); ITarget target = kernel.Get<ITarget>(With.Parameters.ContextVariable("variable", false)); First call was resolved to instance of Target1, second call was resolved to instance of Target2. How to translate this into Ninject 2.0?

  • jQuery-AJAX to rebind dropdown list to results from stored procedure

    - by webworm
    I have a dropdown list of peoples names that is quite long. As many as 2,000 names. I would like to make it easier to find the name the user is interested in by limiting the dropdown list to a subset of names at a time. I have done this by creating a series of 26 links (A, B, C ... Z) that call a method in the code behind that populates the dropdown list with only those names starting with the letter the user clicked. This all works well but I would like to be able to use AJAX to accomplish this update of the dropdown list without a page refresh. I would like to use jQuery for the AJAX functionality rather than ASP.NET AJAX. My problem is I am not sure how to execute the stored procedure and then "rebind" the dropdown list with the new dataset via jQuery AJAX. Any suggestions or resources that might provide and example or walk-through? Thank you.

  • Multiplying char and int together in C part 2

    - by teehoo
    If I do the following: int c0 = CHAR_MAX; //8 bit int c1 = CHAR_MAX; //8-bit int i = c0*c1; //store in 32-bit variable printf("%d\n", i); //prints 16129 We can see that there is no problem with to 8-bit numbers being multiplied together, and producing a 32-bit output. However, if I do int i0 = INT_MAX; //32-bit int i1 = INT_MAX; //32 bit variable long long int ll = i0*i1; //store in 64-bit variable printf("%lld\n", ll); //prints 1..overflow!! In this case, two 32-bit variables were multiplied together, overflowed, and then were assigned to the 64-bit variable. So why did this overflow happen when multiplying the ints, but not the chars? Is it dependent on the default word-size of my machine? (32-bits)

  • What is an example of MVC in PHP?

    - by waiwai933
    I'm trying to understand the MVC pattern. Here's what I think MV is: Model: <?php if($a == 2){ $variable = 'two'; } else{ $variable = 'not two'; } $this->output->addContent($variable); $this->output->displayContent(); ?> View: <?php class output{ private $content; public function addContent($var){ $this->content = 'The variable is '.$var; } public function displayContent(){ include 'header.php'; echo $content; include 'footer.php'; } } ?> Is this right? If so, what is the controller?

  • Usage of Document() function in XSLT 1.0

    - by infant programmer
    I am triggering the transformation using a .NET code, unless I add "EnableDocumentFunction" property to the XSL-Setting, the program throws error saying .. "Usage of Document() function is prohibited", Actually the program is not editable and a kind of read-only .. is it possible to edit the XSL code itself so that I can use document() function?? The sample XSL and XMLs are Here: Sample XML : <?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl" > <xsl:output method="xml" indent="yes"/> <xsl:template match="@* | node()"> <xsl:copy> <xsl:apply-templates select="@* | node()"/> </xsl:copy> </xsl:template> <xsl:variable name="State_Code_Trn"> <State In="California" Out="CA"/> <State In="CA" Out="CA"/> <State In="Texas" Out="TX"/> <State In="TX" Out="TX"/> </xsl:variable> <xsl:template name="testing" match="test_node"> <xsl:variable name="test_val"> <xsl:value-of select="."/> </xsl:variable> <xsl:element name="{name()}"> <xsl:choose> <xsl:when test="document('')/*/xsl:variable[@name='State_Code_Trn'] /State[@In=$test_val]"> <xsl:value-of select="document('')/*/xsl:variable[@name='State_Code_Trn'] /State[@In=$test_val]/@Out"/> </xsl:when> <xsl:otherwise> <xsl:text>Other</xsl:text> </xsl:otherwise> </xsl:choose> </xsl:element> </xsl:template> </xsl:stylesheet> And the sample XML : <?xml version="1.0" encoding="utf-8"?> <root> <test_node>California</test_node> <test_node>CA</test_node> <test_node> CA</test_node> <test_node>Texas</test_node> <test_node>TX</test_node> <test_node>CAA</test_node> <test_node></test_node> </root>

  • MySQL default value based on view

    - by Jake
    Basically I have a bunch of views based on a simple discriminator column (eg. CREATE VIEW tablename AS SELECT * FROM tablename WHERE discrcolumn = "discriminator value"). Upon inserting a new row into this view, it should insert "discriminator value" into discrcolumn. I tried this, but apparently MySQL doesn't figure this out itself, as it throws an error "Field of view viewname underlying table does not have a default value". The discriminator column is set to NOT NULL of course. How do I mend this? Perhaps a pre-insert trigger? UPDATE: Triggers won't work on views, see below comment. Would it work to create a trigger on the table which uses a variable, and set that variable at establishing the connection? For each connection the value of that variable would be the same, but it could differ from other connections. EDIT: This appears to work... Setup: CREATE TRIGGER insert_[tablename] BEFORE INSERT ON [tablename] FOR EACH ROW SET NEW.[discrcolumn] = @variable Runtime: SET @variable = [descrvalue]; INSERT INTO [viewname] ([columnlist]) VALUES ([values]);

  • How to get methods list in scala

    - by skyde
    In language like python and ruby to ask the language what index-related methods its string class supports (which methods’ names contain the word “index”) you can do “”.methods.sort.grep /index/i And in java List results = new ArrayList(); Method[] methods = String.class.getMethods(); for (int i = 0; i < methods.length; i++) { Method m = methods[i]; if (m.getName().toLowerCase().indexOf(“index”) != -1) { results.add(m.getName()); } } String[] names = (String[]) results.toArray(); Arrays.sort(names); return names; How would you do the same thing in Scala?

  • Turning A Stacked List into workable data

    - by BoSox
    In Excel I have a list of names that in the cell appear stacked, and I want each name in its own column. I was thinking Python may be a good way to do this? Example: Joe Smith John Hawk Mike Green Lauren Smith One cell will look exactly like that, with each name on its line within the cell but all of the names contained in the cell. I have 50 cells each with 1-20 stacked names and I want to put each name in its own cell on a given row. So, in my example all of those names would occupy the same row but each would have their own column. Any ideas?

  • Clean up State field with T-SQL?

    - by Pselus
    The State field in our database is a mess. There was no validation when it was filled so we have everything from two letter abbreviations to full state names to misspelled state names to "test" and "xxxx", etc. I am not going to try to handle everything, but for sure I want to fix the correct state names to abbreviations. I have a list of valid state names and abbreviations, but I don't know how I can do this: UPDATE Table SET State = ('AR','AK') WHERE (SELECT * FROM Table WHERE State IN ('Arkansas','Alaska')) Basically, can I update a field to be something from a list by the location it is in another list?

  • Downloading Images to a specific directory using Automator / Applescript

    - by fighella
    Im trying to use a variable in Automator to save images into a specific folder. Strangely when you create a new folder and you use a variable, it allows you to set the base path... but if you try to "Download URL" it does not allow you to select the base path to add the variable onto and it breaks the transaction. Im sure applescript could do a better job, but I can't seem to figure it out. Example. There is a photo gallery called Cats and Dogs. I am able to grab the Cats and Dogs title and make it my variable... it makes a new folder on my desktop called Cats and Dogs (from the Variable)... I am then able to grab all the images in the gallery as a result from "Get Image URL's from webpage"... This works great... then I try to "Download the URLs" and I want to download them to the new "Cats and Dogs" folder I have created. But I can't seem to make that work, because I can't set the path in the Download the URLs box in automator... This ends up being really useful when I have 100 galleries I need to rip to my desktop... Of course I could move the files in the newly created folder by hand once saved... but then I would have to do this for each gallery... Any suggestions?

  • Basic PHP question for Drupal Views theming

    - by oalo
    My PHP and programming knowledge is extremely basic, so this is probably a dumb question: I am theming a View in Drupal 6, and I want to add an id with a consecutive number to each item in the view (first item would have the id #item1, the second #item2, etc). I am customizing the style output (views-view-unformatted--MYVIEWNAME.tpl.php) and the row style output (views-view-fields--MYVIEWNAME.tpl.php), and I want to add a counter variable in the foreach loop in the style output tpl, and then use that variable in the row style output tpl, but the last one is not recognizing the variable. It does not give me any errors, but doesnt print the number. I understand this has probably something to do with variables visibility, how can I declare the counter variable in the style .tpl so I can the use it in the row style .tpl? Thank you
