  • django 'urlize' strings form tect just like twitter

    - by dana
    heyy there i want to parse a text,let's name it 'post', and 'urlize' some strings if they contain a particular character, in a particular position. my 'pseudocode' trial would look like that: def urlize(post) for string in post if string icontains ('#') url=(r'^searchn/$', searchn, name='news_searchn'), then apply url to the string return urlize(post) i want the function to return to me the post with the urlized strings, where necessary (just like twitter does). i don't understand: how can i parse a text, and search for certain strings? is there ok to make a function especially for 'urlizing' some strings? The function should return the entire post, no matter if it has such kind of strings. is there another way Django offers? Thank you

    - by kapil.israni
    I am trying to convert java object to JSON object in Tomcat/jersey using Jackson. And want to suppress serialization(write) of certain properties dynamically. I can use JsonIgnore, but I want to make the ignore decision at runtime. Any ideas?? So as an example below, I want to suppress "id" field when i serialize the User object to JSON.. new ObjectMapper.writeValueAsString(user); class User { private String id = null; private String firstName = null; private String lastName = null; //getters //setters }//end class

  • UrlHelper and ViewContext inside an Authorization Attribute

    - by DM
    I have a scenario that I haven't been able to solve: I'm toying around with creating my own custom authorization attribute for mvc. The main bit of functionality I would like to add is to have the ability to change where the user gets redirected if they are not in a certain role. I don't mind that the system sends them back to the login page if they're not authenticated, but I would like to choose where to send them if they are authenticated but not allowed to access that action method. Here's is what I would like to do: public class CustomAuthorizeAttribute : AuthorizeAttribute { public string Action; public string Controller; protected override bool AuthorizeCore(System.Web.HttpContextBase httpContext) { // if User is authenticated but not in the correct role string url = Url.Action(this.Action, this.Controller); httpContext.Response.Redirect(url); } } And as an added bonus I would like to have access to ViewContext and TempData before I do the redirect. Any thoughts on how I could get instantiate a UrlHelper and ViewContext in the attribute?

  • WCF issues with KnownType for Dictionary

    - by Tom Frey
    Hi, I have a service that implements the following DataMember: [DataMember] public Dictionary<string, List<IOptionQueryResult>> QueryResultItems { get; set; } I have the class "OptionQuerySingleResult" which inherits from IOptionQueryResult. Now, I understand that I need to make the OptionQueryResult type "known" to the Service and thus tried to add the KnownType in various ways: [KnownType(typeof(Dictionary<string, OptionQuerySingleResult[]>))] [KnownType(typeof(Dictionary<string, List<OptionQuerySingleResult>>))] [KnownType(typeof(OptionQuerySingleResult)] However, none of those approaches worked and on the client side I'm either getting that deserialization failed or the server simply aborted the request, causing a connection aborted error. Does anyone have an idea on what's the proper way to get this to work? I'd like to add, the if I change the QueryResultItems definition to use the concrete type, instead of the interface, everything works just fine. Thanks, Tom

  • [Java] Form data transition into entity beans to persist them by the server side ORM

    - by cscsaba242
    Hello guys, Is there any good explanation or tutorial which describes the common way how can we create entity beans from the received data of the form ? The main reason of my question the treating the received ids (e.g id of country,city and so forth) which is the way from the id to entity ? Example: ................Client side form username:String countryid:Integer (could be a drop down) ................Server side entities public class UserBean { String username; CountryBean Country; } public class CountryBean { String cityname; Integer id; } ............................................ Maybe the question is dependent of the used technology, but I guess there is a very common way. I would like to comprehend the conventional approach of this problem. (For the sake of the completeness I would like to save the form data (received by Stripes) by JPA) Thanks advance. cscsaba242

  • How to parse strings representing xml.dom.minidom nodes in python?

    - by Francis Davey
    I have a collection of nodes xml.dom.Node objects created using xml.dom.minidom. I store them (individually) in a database by converting them to a string using the toxml() method of a the Node object. The problem is that I'd sometimes like to be able to convert them back to the appropriate Node object using a parser of some kind. As far as I can see the various libraries shipped with python use Expat which won't parse a string like '' or indeed anything which is not a correct xml string. So, does anyone have any ideas? I realise I could pickle the nodes in some way and then unpickle them, but that feels unpleasant and I'd much rather be storing in a form I can read for maintenance purposes. Surely there is something that will do this?

  • Problem with istringstream in C++

    - by helixed
    Hello, I'm sure I'm just doing something stupid here, but I can't quite figure out what it is. When I try to run this code: #include <iostream> #include <string> #include <sstream> using namespace std; int main(int argc, char *argv[]) { string s("hello"); istringstream input(s, istringstream::in); string s2; input >> s2; cout << s; } I get this error: malloc: *** error for object 0x100016200: pointer being freed was not allocated *** set a breakpoint in malloc_error_break to debug The only thing I can think of is that I allocated s2 on the stack, but I thought strings manage their own content on the heap. Any help here would be appreciated. Thanks, helixed

  • compare previous ENCRYPT() call with new ENCRYPT() call mysql

    - by contagious
    I'm storing a string in mysql with the ENCRYPT() function. I want to fetch a row where that string is matched, but the new ENCRYPT() call gives me a different value, so they never match. This is expected as i'm not (and can't) give it a consistent salt: http://dev.mysql.com/doc/refman/5.0/en/encryption-functions.html#function_encrypt If no salt argument is given, a random value is used. This is the query i'm running that returns empty: SELECT * FROM `table` WHERE ENCRYPT('string') = `enc_string` I know this is possible because this is used by a 3rd party app, but I can't find their query where they do this. Is there a way to force ENCRYPT to use the previous salt, or predict it?

  • Printing elements out of list

    - by chavanak
    Hi, I have a certain check to be done and if the check satisfies, I want the result to be printed. Below is the code: import string import codecs import sys y=sys.argv[1] list_1=[] f=1.0 x=0.05 write_in = open ("new_file.txt", "w") write_in_1 = open ("new_file_1.txt", "w") ligand_file=open( y, "r" ) #Open the receptor.txt file ligand_lines=ligand_file.readlines() # Read all the lines into the array ligand_lines=map( string.strip, ligand_lines ) #Remove the newline character from all the pdb file names ligand_file.close() ligand_file=open( "unique_count_c_from_ac.txt", "r" ) #Open the receptor.txt file ligand_lines_1=ligand_file.readlines() # Read all the lines into the array ligand_lines_1=map( string.strip, ligand_lines_1 ) #Remove the newline character from all the pdb file names ligand_file.close() s=[] for i in ligand_lines: for j in ligand_lines_1: j = j.split() if i == j[1]: print j The above code works great but when I print j, it prints like ['351', '342'] but I am expecting to get 351 342 (with one space in between). Since it is more of a python question, I have not included the input files (basically they are just numbers). Can anyone help me? Cheers, Chavanak

  • A question in java.lang.Integer internal code

    - by Daziplqa
    Hi folks, While looking in the code of the method: Integer.toHexString I found the following code : public static String toHexString(int i) { return toUnsignedString(i, 4); } private static String toUnsignedString(int i, int shift) { char[] buf = new char[32]; int charPos = 32; int radix = 1 << shift; int mask = radix - 1; do { buf[--charPos] = digits[i & mask]; i >>>= shift; } while (i != 0); return new String(buf, charPos, (32 - charPos)); } The question is, in toUnsignedString, why we create a char arr of 32 chars?

  • LINQ To SQL Wildcards

    - by mcass20
    How can I build in wildcards to my LINQ To SQL lambda expression? This is what I have currently: var query = from log in context.Logs select log; foreach (string filter in CustomReport.ExtColsToFilter) { string tempFilter = filter; query = query.Where(Log => Log.FormattedMessage.Contains(tempFilter)); } This works fine up until I try and pass wildcards in the filter string. I'm experimenting with SqlMethods.Like() but to no avail. The filters above look like this: "<key>NID</key><value>mcass</value>". I'd like to be able to pass filters like this: "<key>NID</key><value>%m%</value>"

  • Abstract Factory Using Generics: Is Explicitly Converting a Specified Type to Generic a Bad Practice

    - by Merritt
    The question's title says it all. I like how it fits into the rest of my code, but does it smell? public interface IFoo<T> { T Bar { get; set; } } public class StringFoo : IFoo<string> { public string Bar { get; set; } } public static class FooFactory { public static IFoo<T> CreateFoo<T>() { if (typeof(T) == typeof(string)) { return new StringFoo() as IFoo<T>; } throw new NotImplementedException(); } } UPDATE: this is sort of a duplicate of Is the StaticFactory in codecampserver a well known pattern?

  • NSString within a link

    - by MN
    Hi, I have a UIWebView that loads a link, http://www.google.com/a/datacommsales.net. But I want to have the datacommsales.net part interchangable. What I would like it to be is http://www.google.com/a/stringOne, stringOne being the NSString, so I can set the value of the string and change the link without editing the code. But the link is inside quotes, @"http://www.google.com/a/datacommsales.net", so it doesn't recognize the string. How could I include the string's value as part of the link? Any help is appreciated.

  • sql exception when transferring project from usb to c:\

    - by jello
    I'm working on a C# windows program with Visual Studio 2008. Usually, I work from school, directly on my usb drive. But when I copy the folder on my hard drive at home, an sql exception is unhandled whenever I try to write to the database. it is unhandled at the conn.Open(); line. here's the exception unhandled Database 'L:\system\project\the_project\the_project\bin\Debug\PatientMonitoringDatabase.mdf' already exists. Choose a different database name. Cannot attach the file 'C:\Documents and Settings\Administrator\My Documents\system\project\the_project\the_project\bin\Debug\PatientMonitoringDatabase.mdf' as database 'PatientMonitoringDatabase'. it's weird, because my connection string says |DataDirectory|, so it should work on any drive... here's my connection string: string connStr = "Data Source=.\\SQLEXPRESS;AttachDbFilename=|DataDirectory|\\PatientMonitoringDatabase.mdf; " + "Initial Catalog=PatientMonitoringDatabase; " + "Integrated Security=True";

  • How can I render a Batik SVG Java object in the view portion of a Spring MVC application?

    I am creating and manipulating a SVGOMDocument object in a controller method. How can I render this object in a JSP view? I get very close with the following controller method and <object> tag. @RequestMapping(value = "/seal") public ResponseEntity<SVGDocument> createSeal() throws IOException { InputStream file = new ClassPathResource("seal.svg").getInputStream(); String parser = XMLResourceDescriptor.getXMLParserClassName(); SAXSVGDocumentFactory factory = new SAXSVGDocumentFactory(parser); SVGDocument svg = (SVGDocument) factory.createDocument("http://www.w3.org/2000/svg", file); svg.getElementById("name").getFirstChild().setNodeValue("a test name"); return new ResponseEntity<SVGDocument>(svg, HttpStatus.OK); } <object data="/seal" type="image/svg+xml"></object> This displays a string of XML that is a SVG. The string is in quotes with every XML quote escaped.

  • Efficient way to calculate byte length of a character, depending on the encoding

    - by BalusC
    What's the most efficient way to calculate the byte length of a character, taking the character encoding into account? In UTF-8 for example the characters have a variable byte length, so each character needs to be determined individually. As far now I've come up with this: char c = getItSomehow(); String encoding = "UTF-8"; int length = new String(new char[] { c }).getBytes(encoding).length; But this is clumsy and inefficient in a loop since a new String needs to be created everytime. I can't find other and more efficient ways in the Java API. I imagine that this can be done with bitwise operations like bit shifting, but that's my weak point and I'm unsure how to take the encoding into account here :) If you question the need for this, check this topic.
