  • Improve Efficiency in Array comparison in Ruby

    - by user2985025
    Hi I am working on Ruby /cucumber and have an requirement to develop a comparison module/program to compare two files. Below are the requirements The project is a migration project . Data from one application is moved to another Need to compare the data from the existing application against the new ones. Solution : I have developed a comparison engine in Ruby for the above requirement. a) Get the data, de duplicated and sorted from both the DB's b) Put the data in a text file with "||" as delimiter c) Use the key columns (number) that provides a unique record in the db to compare the two files For ex File1 has 1,2,3,4,5,6 and file2 has 1,2,3,4,5,7 and the columns 1,2,3,4,5 are key columns. I use these key columns and compare 6 and 7 which results in a fail. Issue : The major issue we are facing here is if the mismatches are more than 70% for 100,000 records or more the comparison time is large. If the mismatches are less than 40% then comparison time is ok. Diff and Diff -LCS will not work in this case because we need key columns to arrive at accurate data comparison between two applications. Is there any other method to efficiently reduce the time if the mismatches are more thatn 70% for 100,000 records or more. Thanks

  • what is the best way to optimize my json on an asp.net-mvc site

    - by ooo
    i am currently using jqgrid on an asp.net mvc site and we have a pretty slow network (internal application) and it seems to be taking the grid a long time to load (the issue is both network as well as parsing, rendering) I am trying to determine how to minimized what i send over to the client to make it as fast as possible. Here is a simplified view of my controller action to load data into the grid: [AcceptVerbs(HttpVerbs.Get)] public ActionResult GridData1(GridData args) { var paginatedData = applications.GridPaginate(args.page ?? 1, args.rows ?? 10, i => new { i.Id, Name = "<div class='showDescription' id= '" + i.id+ "'>" + i.Name + "</div>", MyValue = GetImageUrl(_map, i.value, "star"), ExternalId = string.Format("<a href=\"{0}\" target=\"_blank\">{1}</a>", Url.Action("Link", "Order", new { id = i.id }), i.Id), i.Target, i.Owner, EndDate = i.EndDate, Updated = "<div class='showView' aitId= '" + i.AitId + "'>" + GetImage(i.EndDateColumn, "star") + "</div>", }) return Json(paginatedData); } So i am building up a json data (i have about 200 records of the above) and sending it back to the GUI to put in the jqgrid. The one thing i can thihk of is Repeated data. In some of the json fields i am appending HTML on top of the raw "data". This is the same HTML on every record. It seems like it would be more efficient if i could just send the data and "append" the HTML around it on the client side. Is this possible? Then i would just be sending the actual data over the wire and have the client side add on the rest of the HTML tags (the divs, etc) be put together. Also, if there are any other suggestions on how i can minimize the size of my messages, that would be great. I guess at some point these solution will increase the client side load but it may be worth it to cut down on network traffic.

  • Nhibernate Fluent domain Object with Id(x => x.id).GeneratedBy.Assigned not saveable

    - by urpcor
    Hi there, I am using for some legacy db the corresponding domainclasses with mappings. Now the Ids of the entities are calculated by some stored Procedure in the DB which gives back the Id for the new row.(Its legacy, I cant change this) Now I create the new entity , set the Id and Call Save. But nothing happens. no exeption. Even NH Profiler does not say a bit. its as the Save call does nothing. I expect that NH thinks that the record is already in the db because its got an Id already. But I am using Id(x = x.id).GeneratedBy.Assigned() and intetionally the Session.Save(object) method. I am confused. I saw so many samples there it worked. does any body have any ideas about it? public class Appendix { public virtual int id { get; set; } public virtual AppendixHierarchy AppendixHierachy { get; set; } public virtual byte[] appendix { get; set; } } public class AppendixMap : ClassMap<Appendix> { public AppendixMap () { WithTable("appendix"); Id(x => x.id).GeneratedBy.Assigned(); References(x => x.AppendixHierachy).ColumnName("appendixHierarchyId"); Map(x => x.appendix); } }

  • Incrementing value by one over a lot of rows

    - by Andy Gee
    Edit: I think the answer to my question lies in the ability to set user defined variables in MySQL through PHP - the answer by Multifarious has pointed me in this direction Currently I have a script to cycle over 10M records, it's very slow and it goes like this: I first get a block of 1000 results in an array similar to this: $matches[] = array('quality_rank'=>46732, 'db_id'=>5532); $matches[] = array('quality_rank'=>12324, 'db_id'=>1234); $matches[] = array('quality_rank'=>45235, 'db_id'=>8345); $matches[] = array('quality_rank'=>75543, 'db_id'=>2562); I then cycle through them one by one and update the record $mult = count($matches)*2; foreach($matches as $m) { $rank++; $score = (($m[quality_rank] + $rank)/($mult))*100; $s = "UPDATE `packages_sorted` SET `price_rank` = '".$rank."', `deal_score` = '".$score."' WHERE `db_id` = '".$m[db_id]."' LIMIT 1"; } It seems like this is a very slow way of doing it but I can't find another way to increment the field price_rank by one each time. Can anyone suggest a better method. Note: Although I wouldn't usually store this kind of value in a database I really do need on this occasion for comparison search queries later on in the project. Any help would be kindly appreciated :)

  • SQL trigger to delete rows from database

    - by wpearse
    I have an industrial system that logs alarms to a remotely hosted MySQL database. The industrial system inserts a new row whenever a property of the alarm changes (such as the time the alarm was activated, acknowledged or switched off) into a table named 'alarms'. I don't want multiple records for each alarm, so I have set up two database triggers. The first trigger mirrors each new record to a second table, creating/updating rows as required: CREATE TRIGGER `mirror_alarms` BEFORE INSERT ON `alarms` FOR EACH ROW INSERT INTO `alarm_display` (Tag,...,OffTime) VALUES (new.Tag,...,new.OffTime) ON DUPLICATE KEY UPDATE OnDate=new.OnDate,...,OffTime=new.OffTime The second trigger should execute after the first and (ideally) delete all rows from the alarms table. (I used the Tag property of the alarm because the Tag property never changes, although I suspect I could just use a 'DELETE FROM alarms WHERE 1' statement to the same effect). CREATE TRIGGER `remove_alarms` AFTER INSERT ON `alarms` FOR EACH ROW DELETE FROM alarms WHERE Tag=new.Tag My problem is that the second trigger doesn't appear to run, or if it does, the second trigger doesn't delete any rows from the database. So here's the question: why does my second trigger not do what I expect it to do?

  • An Erroneous SQL Query makes browser hang until script timeout exceeded

    - by Jimbo
    I have an admin page in a Classic ASP web application that allows the admin user to run queries against the database (SQL Server 2000) Whats really strange is that if the query you send has an error in it (an invalid table join, a column you've forgotten to group by etc) the BROWSER hangs (CPU usage goes to maximum) until the SERVER script timeout is exceeded and then spits out a timeout exceeded error (server and browser are on different machines, so not sure how this happens!) I have tried this in IE 8 and FF 3 with the same result. If you run that same query (with errors) directly from SQL Enterprise Manager, it returns the real error immediately. Is this a security feature? Does anyone know how to turn it off? It even happens when the connection to the database is using 'sa' credentials so I dont think its a security setting :( Dim oRS Set oRS = Server.CreateObject("ADODB.Recordset") oRS.ActiveConnection = sConnectionString // run the query - this is for the admin only so doesnt check for sql safe commands etc. oRS.Open Request.Form("txtSQL") If Not oRS.EOF Then // list the field names from the recordset For i = 0 to oRS.Fields.Count - 1 Response.Write oRS.Fields(i).name & "&nbsp;" Next // show the data for each record in the recordset While Not oRS.EOF For i = 0 to oRS.Fields.Count - 1 Response.Write oRS.Fields(i).value & "&nbsp;" Next Response.Write "<br />" oRS.Movenext() Wend End If

  • AWK: compare apache dates without using regular expression

    - by smallmeans
    I'm writing a loganalysis application and wanted to grab apache log records between two certain dates. Assume that a date is formated as such: 22/Dec/2009:00:19 (day/month/year:hour:minute) Currently, I'm using a regular expression to replace the month name with its numeric value, remove the separators, so the above date is converted to: 221220090019 making a date comparison trivial.. but.. Running a regex on each record for large files, say, one containing a quarter million records, is extremely costly.. is there any other method not involving regex substitution? Thanks in advance Edit: here's the function doing the convertion/comparison function dateInRange(t, from, to) { sub(/[[]/, "", t); split(t, a, "[/:]"); match("JanFebMarAprMayJunJulAugSepOctNovDec", a[2]); a[2] = sprintf("%02d", (RSTART + 2) / 3); s = a[3] a[2] a[1] a[4] a[5]; return s >= from && s <= to; } "from" and "to" are the intervals in the aforementioned format, and "t" is the raw apache log date/time field (e.g [22/Dec/2009:00:19:36)

  • Unable to save data in database manually and get latest auto increment id, cakePHP

    - by shabby
    I have checked this question as well and this one as well. I am trying to implement the model described in this question. What I want to do is, on the add function of message controller, create a record in thread table(this table only has 1 field which is primary key and auto increment), then take its id and insert it in the message table along with the user id which i already have, and then save it in message_read_state and thread_participant table. This is what I am trying to do in Thread Model: function saveThreadAndGetId(){ //$data= array('Thread' => array()); $data= array('id' => ' '); //Debugger::dump(print_r($data)); $this->save($data); debug('id: '.$this->id); $threadId = $this->getInsertID(); debug($threadId); $threadId = $this->getLastInsertId(); debug($threadId); die(); return $threadId; } $data= array('id' => ' '); This line from the above function adds a row in the thread table, but i am unable to retrieve the id. Is there any way I can get the id, or am I saving it wrongly? Initially I was doing the query thing in the message controller: $this->Thread->query('INSERT INTO threads VALUES();'); but then i found out that lastId function doesnt work on manual queries so i reverted.

  • MySQL to SQL Server ODBC Connector?

    - by Scott C.
    My boss wants to have data in MySQL DBs used for our website to be "linked and synced" with a Financial Server that has its DB in SQL Server. Sooooo...even though I have no idea how to accomplish this, this just sounds like an absolute nightmare especially since the MySQL DB is most likely going to be hosted in the cloud and not on a machine next to the Financial Server. Any ideas how to accomplish this? (within reason?) Also, his big thing is he wants to basically pull up the data from any record a user enters and using data pulled from that do all sorts of calculations using ANOTHER program that stores its data (apparently) in SQL Server. Thinking of all the data I might have to convert makes me very uneasy. Please tell a ODBC eliminates complicated junk like this. :/ I'm trying to talk him into just having MySQL do a nightly dump into a CSV file or something and using that (rather than connector) to update the SQL Server DBs. I guess I'm just not that comfortable with a server and/or programming I have no say over being connected DIRECTLY to my MySQL DB for the website. If there's no good answer for this, can anyone offer a suggestion as to what I can say to talk him out of this? (I'm a low-level IT guy w/ a decent grasp on programming...but I'm no expert - should I try to push this off to a seasoned IT pro?) Thanks in advance.

  • Designing a chain of states

    - by devoured elysium
    I want to model a kind of FSM(Finite State Machine). I have a sequence of states (let's say, from StateA to StateZ). This sequence is called a Chain and is implemented internally as a List. I will add states by the order I want them to run. My purpose is to be able to make a sequence of actions in my computer (for example, mouse clicks). (I know this has been done a zillion times). So a state is defined as a: boolean Precondition() <- Checks to see if for this state, some condition is true. For example, if I want to click in the Record button of a program, in this method I would check if the program's process is running or not. If it is, go to the next state in the chain list, otherwise, go to what was defined as the fail state (generally is the first state of them all). IState GetNextState() <- Returns the next state to evaluate. If Precondition() was sucessful, it should yield the next state in the chain otherwise it should yield the fail state. Run() Simply checks the Precondition() and sets the internal data so GetNextState() works as expected. So, a naive approach to this would be something like this: Chain chain = new Chain(); //chain.AddState(new State(Precondition, FailState, NextState) <- Method structure chain.AddState(new State(new WinampIsOpenCondition(), null, new <problem here, I want to referr to a state that still wasn't defined!>); The big problem is that I want to make a reference to a State that at this point still wasn't defined. I could circumvent the problem by using strings when refrering to states and using an internal hashtable, but isn't there a clearer alternative? I could just pass only the pre-condition and failure states in the constructor, having the chain just before execution put in each state the correct next state in a public property but that seems kind of awkward.

  • Database locking: ActiveRecord + Heroku

    - by JP
    I'm building a Sinatra based app for deployment on Heroku. You can imagine it like a standard URL shortener but where old shortcodes expire and become available for new URLs (I realise this is a silly concept but its easier to explain this way). I'm representing the shortcode in my database as an integer and redefining its reader to give a nice short and unique string from the integer. As some rows will be deleted, I've written code that goes thru all the shortcode integers and picks the first free one to use just before_save. Unfortunately I can make my code create two rows with identical shortcode integers if I run two instances very quickly one after another, which is obviously no good! How should I implement a locking system so that I can quickly save my record with a unique shortcode integer? Here's what I have so far: Chars = ('a'..'z').to_a + ('A'..'Z').to_a + ('0'..'9').to_a CharLength = Chars.length class Shorts < ActiveRecord::Base before_save :gen_shortcode after_save :done_shortcode def shortcode i = read_attribute(:shortcode).to_i return '0' if i == 0 s = '' while i > 0 s << Chars[i.modulo(CharLength)] i /= 62 end s end private def gen_shortcode shortcode = 0 self.class.find(:all,:order=>"shortcode ASC").each do |s| if s.read_attribute(:shortcode).to_i != shortcode # Begin locking? break end shortcode += 1 end write_attribute(:shortcode,shortcode) end def done_shortcode # End Locking? end end

  • Converting rows to Columns in SQL

    - by Ram
    I have a table (actually a view, but simplified my example to a table) which gives me some data like this id CompanyName website 1 Google google.com 2 Google google.net 3 Google google.org 4 Google google.in 5 Google google.de 6 Microsoft Microsoft.com 7 Microsoft live.com 8 Microsoft bing.com 9 Microsoft hotmail.com I am looking to convert it to get a result like this CompanyName website1 website2 website3 website 4 website5 website6 ----------- ------------- ---------- ---------- ----------- --------- -------- Google google.com google.net google.org google.in google.de NULL Microsoft Microsoft.com live.com bing.com hotmail.com NULL NULL I have looked into pivot but looks like the record(row values) cannot be dynamic (i.e can only be certain predefined values). Also, if there are more than 6 websites, I want to limit it to the first 6 Dynamic pivot makes sense, but I would have to incorporate it into my view ?? Is there a simpler solution for this ? Here are the SQL scripts CREATE TABLE [dbo].[Company]( [id] [int] NULL, [CompanyName] [varchar](50) NULL, [website] [varchar](50) NULL ) ON [PRIMARY] GO insert into company values (1,'Google','google.com') insert into company values (2,'Google','google.net') insert into company values (3,'Google','google.org') insert into company values (4,'Google','google.in') insert into company values (5,'Google','google.de') insert into company values (6,'Microsoft','Microsoft.com') insert into company values (7,'Microsoft','live.com') insert into company values (8,'Microsoft','bing.com') insert into company values (9,'Microsoft','hotmail.com')

  • How To Join Tables from Two Different Contexts with LINQ2SQL?

    - by RSolberg
    I have 2 data contexts in my application (different databases) and need to be able to query a table in context A with a right join on a table in context B. How do I go about doing this in LINQ2SQL? Why?: We are using a SaaS product for tracking our time, projects, etc. and would like to send new service requests to this product to prevent our team from duplicating data entry. Context A: This db stores service request information. It is a third party DB and we are not able to make changes to the structure of this DB as it could have unintended non-supportable consequences downstream. Context B: This data stores the "log" data of service requests that have been processed. My team and I have full control over this DB's structure, etc. Unprocessed service requests should find their way into this DB and another process will identify it as not being processed and send the record to the SaaS product. This is the query that I am looking to modify. I was able to do a !list.Contains(c.swHDCaseId) initially, but this cannot handle more than 2100 items. Is there a way to add a join to the other context? var query = (from c in contextA.Cases where monitoredInboxList.Contains(c.INBOXES.inboxName) select new { //setup fields here... });

  • MySQL - What is wrong with this query or my database? Terrible performance.

    - by Moss
    SELECT * from `employees` a LEFT JOIN (SELECT phone1 p1, count(*) c, FROM `employees` GROUP BY phone1) b ON a.phone1 = b.p1; I'm not sure if it is this query in particular that has the problem. I have been getting terrible performance in general with this database. The table in question has 120,000 rows. I have tried this particular query remotely and locally with the MyISAM and InnoDB engines, with different types of joins, and with and without an index on phone1. I can get this to complete in about 4 minutes on a 10,000 row table successfully but performance drops exponentially with larger tables. Remotely it will lose connection to the server and locally it brings my system to its knees and seems to go on forever. This query is only a smaller step I was trying to do when a larger query couldn't complete. Maybe I should explain the whole scenario. I have one big flat ugly table that lists a bunch of people and their contact info and the info of the companies they work for. I'm trying to normalize the database and intelligently determine which phone numbers apply to individual people and which apply to an office location. My reasoning is that if a phone number occurs multiple times and the number of occurrence equals the number of times that the street address it is attached to occurs then it must be an office number. So the first step is to count each phone number grouping by phone number. Normally if you just use COUNT()...GROUP BY it will only list the first record it finds in that group so I figured I have to join the full table to the count table where the phone number matches. This does work but as I said I can't successfully complete it on any table much larger than 10,000 rows. This seems pathetic and this doesn't seem like a crazy query to do. Is there a better way to achieve what I want or do I have to break my large table into 12 pieces or is there something wrong with the table or db?

  • codeigniter mulitple LIKE db query using associative array- but all from the same column name...?

    - by Inigo
    Hi, I'm trying to query my database using codeigniter's active record class. I have a number of blog posts stored in a table. The query is for a search function, which will pull out all the posts that have certain categories assigned to them. So the 'category' column of the table will have a list of all the categories for that post in no particular order, separated by commas, like so: Politics,History,Sociology.. etc. If a user selects, say, Politics and History, The titles of all the posts that have BOTH these categories should be returned. Right? So, the list of categories queried will be the array $cats. I thought this would work- foreach ($cats as $cat){ $this->db->like('categories',$cat); } By Producing this- $this-db-like('categories','Politics'); $this-db-like('categories','History'); (Which would produce- 'WHERE categories LIKE '%Politics%' AND categories LIKE '%History%') But it doesn't work, it seems to only produce the first statement. The problem I guess is that the column name is the same for each of the chained queries. There doesn't seem to be anything in the CI user guide about this (http://codeigniter.com/user_guide/database/active_record.html) as they seem to assume that each chained statement is going to be for a different column name. Does anyone know how I could do this? Thanks! edit- Of course it is not possible to use an associative array in one statement as it would have to contain duplicate keys- in this case every key would have to be 'categories'...

  • Android: How to periodically send location to a server

    - by Mark
    Hi, I am running a Web service that allows users to record their trips (kind of like Google's MyTracks) as part of a larger app. The thing is that it is easy to pass data, including coords and other items, to the server when a user starts a trip or ends it. Being a newbie, I am not sure how to set up a background service that sends the location updates once every (pre-determined) period (min 3 minutes, max 1 hr) until the user flags the end of the trip, or until a preset amount of time elapses. Once the trip is started from the phone, the server responds with a polling period for the phone to use as the interval between updates. This part works, in that I can display the response on the phone, and my server registers the user's action. Similarly, the trip is closed server-side upon the close trip request. However, when I tried starting a periodic tracking method from inside the StartTrack Activity, using requestLocationUpdates(String provider, long minTime, float minDistance, LocationListener listener) where minTime is the poll period from the server, it just did not work, and I'm not getting any errors. So it means I'm clueless at this point, never having used Android before. I have seen many posts here on using background services with handlers, pending intents, and other things to do similar stuff, but I really don't understand how to do it. I would like the user to do other stuff on the phone while the updates are going on, so if you guys could point me to a tutorial that shows how to actually write background services (maybe these run as separate classes?) or other ways of doing this, that would be great. Thanks!

  • Should I be using Expression Blend to design really dynamic UIs?

    - by Robert Rossney
    My company's product is, at its core, a framework for developing metadata-driven UIs. I don't know how to characterize it less succinctly than that, and hope I won't need to for purposes of this question, but we'll see. I've been trying to come up to speed on WPF, and have been building UI prototypes here and there, and recently I decided to see if I could use Expression Blend to help with the design of these UIs. And I'm pretty mystified at this point. It appears to me as though Expresssion Blend is designed with the expectation that you already know all of the objects that are going to be present in the UI at design time. But our program generates these object dynamically at runtime. For instance, a data row might be presented in a horizontal StackPanel containing alternating TextBlocks (for captions) and TextBoxes (for data fields). The number of these objects depends on metadata about the number of columns in the data row. I can, pretty readily, write code that runs through a metadata record and populates a StackPanel dynamically, setting up the binding of all of the controls to properties in either the data or metadata. (A TextBox's Width might be bound to metadata, while its Text is bound to data.) But I can't even begin to figure out how to do something like this in Expression Blend. I can manually create all these controls, so that I have a set of controls that I can apply styles to and work out the visual design of the app, but it's really a pain to do this. I can write code that goes through my data model and emits XAML for all these controls, I suppose, and then copy and paste it. But I'm going to feel really stupid if it turns out there a way to do this sort of thing in Expression Blend and I've dropped back and punted because I'm too dim to figure out the right way to think of it. Is this enough information for someone to try formulating an answer?

  • C#/.NET: FInd out whether a server exists, Query DNS for SVC records.

    - by TomTom
    Writing a cleint/Server tool I am tasked trying to find a server to connect to. I would love to make things as easy as possible for the user. As such, my idea is to: CHeck whether specific servers (coded by name) exist (like "mail.xxx" for a mail server, for example - my exampüle is not a mail server;) Query otherwise for DNS SVC records, allowing the admin to configure a server location for a specific serivce (that the client connects to). The result is that the user may have to enter only a domain name, possibly even not even that (using the registered standard domain of the computer in a LAN environment). Anyone ideas how: To find out whether a server exists and answers (i.e. is online) in the fastest way? TCP can take a long time if the server is not there. A UDP style ping sounds like a good idea to me. PING itself may be unavailable. Anyonw knows how to ask from withint .NET best for a SVC record in a specific (the default) domain?

  • Need advanced mod_rewrite assistance

    - by user1647719
    This is driving me bananas. I have tried multiple fixes, and have even found a generator (generateit.net/mod-rewrite/) to create my .htaccess files, but I cannot get this to work. The .htaccess file is being read - if I put garbage characters in, I get a 500 server error. Also, mod rewrite was working in a simpler format, but the client wants even more SEO, so here I am. My intention: Take the url of brinkofdesign.com/portfolio/123/456/some_seo_text.html and send it to brinkofdesign.com/brink_portfolio.php?catid=123&locationid=456. The full contents of my .htaccess file are: Options +FollowSymlinks RewriteEngine on RewriteBase / RewriteRule ^portfolio([^/]*)/([^/]*)/([^/]*)\.html$ /portfolio_brink.php?catid=$1&locationid=$2&page=$3 [NC,L] RewriteRule ^(.*)blog(.+)([0-9+])(.+).html$ blog.php?blogid=$3 [NC,L] RewriteRule ^blog.xml$ blogfeed.php The blog and blogfeed parts work fine. If it matters, I do have an actual portfolio.php page - could this be breaking it? There is no actual /portfolio/ folder - this is just part of the SEO nme. Also, the host is 1and1.com. Real life tests: brinkofdesign.com/portfolio/1/1/birmingham_al_corporate_branding.html loads my actual portfolio.php page - which is supposed to be a landing page for the portfolio, as opposed to the brink_portfolio.php page, which is my detail record page. No variables are passed (echoing out the contents of the $_GET array gives an empty array). Typing in an non SEO link like brinkofdesign.com/brink_portfolio.php?catid=1&locationid=1 does work correctly. Gurus, please help me!

  • Square Brackets in Python Regular Expressions (re.sub)

    - by user1479984
    I'm migrating wiki pages from the FlexWiki engine to the FOSwiki engine using Python regular expressions to handle the differences between the two engines' markup languages. The FlexWiki markup and the FOSwiki markup, for reference. Most of the conversion works very well, except when I try to convert the renamed links. Both wikis support renamed links in their markup. For example, Flexwiki uses: "Link To Wikipedia":[http://www.wikipedia.org/] FOSwiki uses: [[http://www.wikipedia.org/][Link To Wikipedia]] both of which produce something that looks like I'm using the regular expression renameLink = re.compile ("\"(?P<linkName>[^\"]+)\":\[(?P<linkTarget>[^\[\]]+)\]") to parse out the link elements from the FlexWiki markup, which after running through something like "Link Name":[LinkTarget] is reliably producing groups <linkName> = Link Name <linkTarget = LinkTarget My issue occurs when I try to use re.sub to insert the parsed content into the FOSwiki markup. My experience with regular expressions isn't anything to write home about, but I'm under the impression that, given the groups <linkName> = Link Name <linkTarget = LinkTarget a line like line = renameLink.sub ( "[[\g<linkTarget>][\g<linkName>]]" , line ) should produce [[LinkTarget][Link Name]] However, in the output to the text files I'm getting [[LinkTarget [[Link Name]] which breaks the renamed links. After a little bit of fiddling I managed a workaround, where line = renameLink.sub ( "[[\g<linkTarget>][ [\g<linkName>]]" , line ) produces [[LinkTarget][ [[Link Name]] which, when displayed in FOSwiki looks like <[[Link Name> <--- Which WORKS, but isn't very pretty. I've also tried line = renameLink.sub ( "[[\g<linkTarget>]" + "[\g<linkName>]]" , line ) which is producing [[linkTarget [[linkName]] There are probably thousands of instances of these renamed links in the pages I'm trying to convert, so fixing it by hand isn't any good. For the record I've run the script under Python 2.5.4 and Python 2.7.3, and gotten the same results. Am I missing something really obvious with the syntax? Or is there an easy workaround?

  • Select rows from table1 and all the children from table2 into an object

    - by Patrick
    I want to pull data from table "Province_Notifiers" and also fetch all corresponding items from table "Province_Notifier_Datas". The table "Province_Notifier" has a guid to identify it (PK), table "Province_Notifier_Datas" has a column called BelongsToProvinceID witch is a foreign key to the "Province_Notifier" tables guid. I tried something like this: var records = from data in ctx.Province_Notifiers where DateTime.Now >= data.SendTime && data.Sent == false join data2 in ctx.Province_Notifier_Datas on data.Province_ID equals data2.BelongsToProvince_ID select new Province_Notifier { Email = data.Email, Province_ID = data.Province_ID, ProvinceName = data.ProvinceName, Sent = data.Sent, UserName = data.UserName, User_ID = data.User_ID, Province_Notifier_Datas = (new List<Province_Notifier_Data>().AddRange(data2)) }; This line is not working and i am trying to figure out how topull the data from table2 into that Province_Notifier_Datas variable. Province_Notifier_Datas = (new List<Province_Notifier_Data>().AddRange(data2)) I can add a record easily by adding the second table row into the Province_Notifier_Datas but i can't fetch it back. Province_Notifier dbNotifier = new Province_Notifier(); // set some values for dbNotifier dbNotifier.Province_Notifier_Datas.Add( new Province_Notifier_Data { BelongsToProvince_ID = userInput.Value.ProvinceId, EventText = GenerateNotificationDetail(notifierDetail) }); This works and inserts the data correctly into both tables. Edit: These error messages is thrown: Cannot convert from 'Province_Notifier_Data' to 'System.Collections.Generic.IEnumerable' If i look in Visual Studio, the variable "Province_Notifier_Datas" is of type System.Data.Linq.EntitySet The best overloaded method match for 'System.Collections.Generic.List.AddRange(System.Collections.Generic.IEnumerable)' has some invalid arguments Edit: var records = from data in ctx.Province_Notifiers where DateTime.Now >= data.SendTime && data.Sent == false join data2 in ctx.Province_Notifier_Datas on data.Province_ID equals data2.BelongsToProvince_ID into data2list select new Province_Notifier { Email = data.Email, Province_ID = data.Province_ID, ProvinceName = data.ProvinceName, Sent = data.Sent, UserName = data.UserName, User_ID = data.User_ID, Province_Notifier_Datas = new EntitySet<Province_Notifier_Data>().AddRange(data2List) }; Error 3 The name 'data2List' does not exist in the current context.

  • How to get a debug flow of execution in C++

    - by Rich
    Hi, I work on a global trading system which supports many users. Each user can book,amend,edit,delete trades. The system is regulated by a central deal capture service. The deal capture service informs all the user of any updates that occur. The problem comes when we have crashes, as the production environment is impossible to re-create on a test system, I have to rely on crash dumps and log files. However this doesn't tell me what the user has been doing. I'd like a system that would (at the time of crashing) dump out a history of what the user has been doing. Anything that I add has to go into the live environment so it can't impact performance too much. Ideas wise I was thinking of a MACRO at the top of each function which acted like a stack trace (only I could supply additional user information, like trade id's, user dialog choices, etc ..) The system would record stack traces (on a per thread basis) and keep a history in a cyclic buffer (varying in size, depending on how much history you wanted to capture). Then on crash, I could dump this history stack. I'd really like to hear if anyone has a better solution, or if anyone knows of an existing framework? Thanks Rich

  • CodeIgniter: Where should a particular functionality go ?

    - by Samnan
    I have an application in codeigniter and a page needs to perform the following tasks 1 - controller decides which model to use based of the url and parameters 2 - controller loads the model and get the data from it 3 - controller formats the data in a particular format, depending on the items in it 4 - controller loads a common view, which will display the data (formatted data contains simple display fields) now there is a search page, which needs to do a text query against all of the possible text fields in database in all tables. It needs to show each type of data in its own formatted output on a single page as a list. The problem: The search controller can do the search, dynamically load model for each record type, and get the data from model. Problem comes when the data needs to be formatted. It looks that ideally the search controller should load another controller which will provide formatted data ... There is where it gets out of control ... My question is: What am I doing wrong? Is there any better way to do this? How would you do the same to solve the problem?
