  • RTTI Delphi Create as TValue an n-dimensional matrix.

    - by user558126
    Good day, I had tried to make recurrent function to return a TValue as a n-dimensional. matrix(2D, 3D, 4D...) for example, this procedure will show a n-dimensional matrix(it will list all elements from a n-dimensional matrix as TValue variable): Procedure Show(X:TValue); var i:integer; begin if x.IsArray then begin for i:=0 to x.GetArrayLength-1 do show(x.GetArrayElement(i)); writeln; end else write(x.ToString,' '); end; I don't understand how to create a function to create from a TValue an n-dimensional matrix. For example i need a Function CreateDynArray(Dimensions:array of integer; Kind:TTypeKind):TValue; and the function will return a TValue which is a dynamic array how contain the dimenssions for example: Return=CreateDynArray([2,3],tkInteger); will return a TValue as tkDynArray and if i will show(Return) will list 0 0 0 0 0 0 Thank you very much, and have a nice day!

  • ListView causing OutOfMemory Error

    - by Michael
    So I am not really given a reason to the right of this error message. I am not exactly sure why this is happening but my guess though is that it has to do with the fact that there are around ~50 good quality drawables. Upon scrolling really fast, the app crashes. I feel as if I am mitigating most common issues with ListView and crashing such as using View Holders as well as only initiating the inflater once. Process: com.example.michael.myandroidappactivity, PID: 20103 java.lang.OutOfMemoryError at android.graphics.BitmapFactory.nativeDecodeAsset(Native Method) Here is the code public class ImageAdapter extends BaseAdapter { private Context context; private ArrayList<Integer> imageIds; private static LayoutInflater inflater; public ImageAdapter(Context _context, ArrayList<Integer> _imageIds) { context = _context; imageIds = _imageIds; } @Override public int getCount() { return imageIds.size(); } @Override public Object getItem(int position) { return null; } @Override public long getItemId(int position) { return 0; } static class ViewHolder{ ImageView img; } @Override public View getView(int position, View convertView, ViewGroup parent) { ViewHolder holder = null; View rowView = null; if(rowView==null) { LayoutInflater inflater = (LayoutInflater) context .getSystemService(Context.LAYOUT_INFLATER_SERVICE); rowView = inflater.inflate(R.layout.listview_layout, parent, false); holder = new ViewHolder(); holder.img = (ImageView) rowView.findViewById(R.id.flag); rowView.setTag(holder); } else { holder = (ViewHolder) rowView.getTag(); } holder.img.setImageResource(imageIds.get(position)); return rowView; } }

  • Need some advice before starting coding my next iPhone app...

    - by Tom
    Hi! I need some advice about how should I start coding something. So here is the context: I've just finished building a CMS that manage a SQLite database. My application will be picking this database and use its content as the application's content. So far it's pretty simple. The application will have a navigation that will browse through various workflows, and once at the end workflow, it'll show contents from the database. A consultation kind a thing, example: Liquids - Juice - Orange Juice - Informations about Orange Juice. For my SQLite transactions, so far I believe I'll be using fmdb. It looks like a great wrapper. Here's a simple schema from one of the database: Workflow: id: { type: integer(3), primary: true, autoincrement: true } workflow_id: { type: integer(1) } name: { type: string(255) } That table's rows will be my navigations. Do you believe I should use a navigation controller? If so, then how could I generate the navigation tree from it? I have a good working knowledge of Objective-C and Foundation framework, but never went too far with it so that is why I'm asking before starting in the wrong direction :) Thanks a lot.

  • Find the number of congruent triangles?

    - by avd
    Say I have a square from (0,0) to (z,z). Given a triangle within this square which has integer coordinates for all its vertices. Find out the number of triangles within this square which are congruent to this triangle and have integer coordinates. My algorithm is as follows-- 1) Find out the minimum bounding rectangle(MBR) for the given triangle. 2) Find out the number of congruent triangles, y within that MBR, obtained after reflection, rotation of the given triangle. y can be either 2,4 or 8. 3) Now find out how many such MBR's can be drawn within the given big square, say x; (This is similar to finding number of squares on a chess board) 4) x*y is the required answer. Am I counting some triangles more than once or I am missing something by this algorithm? It is a problem on online judge? It gives me wrong answer. I have thought a lot about it, but I am not able to figure it out.

  • Randomly sorting an array

    - by Cam
    Does there exist an algorithm which, given an ordered list of symbols {a1, a2, a3, ..., ak}, produces in O(n) time a new list of the same symbols in a random order without bias? "Without bias" means the probability that any symbol s will end up in some position p in the list is 1/k. Assume it is possible to generate a non-biased integer from 1-k inclusive in O(1) time. Also assume that O(1) element access/mutation is possible, and that it is possible to create a new list of size k in O(k) time. In particular, I would be interested in a 'generative' algorithm. That is, I would be interested in an algorithm that has O(1) initial overhead, and then produces a new element for each slot in the list, taking O(1) time per slot. If no solution exists to the problem as described, I would still like to know about solutions that do not meet my constraints in one or more of the following ways (and/or in other ways if necessary): the time complexity is worse than O(n). the algorithm is biased with regards to the final positions of the symbols. the algorithm is not generative. I should add that this problem appears to be the same as the problem of randomly sorting the integers from 1-k, since we can sort the list of integers from 1-k and then for each integer i in the new list, we can produce the symbol ai.

  • Logback: Logging with two loggers

    - by gammay
    I would like to use slf4j+logback for two purposes in my application - log and audit. For logging, I log the normal way: static final Logger logger = LoggerFactory.getLogger(Main.class); logger.debug("-> main()"); For Audit, I create a special named logger and log to it: static final Logger logger = LoggerFactory.getLogger("AUDIT_LOGGER"); Object[] params = { new Integer(1) /* TenantID */, new Integer(10) /* UserID */, msg}; logger.info("{}|{}|{}", params); logback configuration: <logger name="AUDIT_LOGGER" level="info"> <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> <encoder> <pattern>%d{HH:mm:ss.SSS}|%msg%n </pattern> </encoder> </appender> </logger> <root level="all"> <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> <encoder> <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n </pattern> </encoder> </appender> </root> Problem: Messages logged through audit logger appear twice - once under the AUDIT_LOGGER and once under the root logger. 14:41:57.975 [main] DEBUG com.gammay.example.Main - - main() 14:41:57.978|1|10|welcome to main 14:41:57.978 [main] INFO AUDIT_LOGGER - 1|10|welcome to main How can I make sure audit messages appear only once under the audit logger?

  • [Netbeans 6.9] Java MethodOverloading error with double values

  • How to programmatically set the text of a cell of database in VB.Net?

    - by manuel
    I have a Microsoft Access database file connected to VB.NET. In the database table, I have a 'No.' and a 'Status' column. Then I have a textbox where I can input an integer. I also have a button, which will change the data cell in 'Status' where 'No.' = txtTitleNo.Text(), when I click it. Let's say I want the 'Status' cell to be changed to "Reserved". What codes should I put in the BtnReserve_Click? Here is the code: Public Class theForm Dim con As New OleDb.OleDbConnection Dim ds As New DataSet Dim daTitles As OleDb.OleDbDataAdapter Private Sub theForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load con.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=|DataDirectory|\db1.mdb" con.Open() daTitles = New OleDb.OleDbDataAdapter("SELECT * FROM Titles", con) daTitles.Fill(ds, "Titles") DataGridView1.DataSource = ds.Tables("Titles") DataGridView1.AutoResizeColumns() End Sub Private Sub BtnReserve_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnReserve.Click Dim daReserve As OleDb.OleDbCommand For i As Integer = 1 TReservedo DataGridView1.RowCount() If i = Val(txtTitleNo.Text()) Then daReserve = New OleDb.OleDbCommand("UPDATE Titles SET Status = 'Reserved' WHERE No = '" & i & "'", con) daReserve.ExecuteNonQuery() End If Next Dim cb As New OleDb.OleDbCommandBuilder(daTitles) daTitles.Update(ds, "Titles") End Sub This code still does not change the 'Status'. What should I do?

  • Database layout for an application with geocoding features using geokit

    - by vooD
    I'm developing a real estate web catalogue and want to geocode every ad using geokit gem. My question is what would be the best database layout from the performance point if i want to make search by country, city of the selected country, administrative area or nearest metro station of the selected city. Available countries, cities, administrative areas and metro sations should be defined by the administrator of catalogue and must be validated by geocoding. I came up with single table: create_table "geo_locations", :force => true do |t| t.integer "geo_location_id" #parent geo location (ex. country is parent geo location of city t.string "country", :null => false #necessary for any geo location t.string "city", #not null for city geo location and it's children t.string "administrative_area" #not null for administrative_area geo location and it's children t.string "thoroughfare_name" #not null for metro station or street name geo location and it's children t.string "premise_number" #house number t.float "lng", :null => false t.float "lat", :null => false t.float "bound_sw_lat", :null => false t.float "bound_sw_lng", :null => false t.float "bound_ne_lat", :null => false t.float "bound_ne_lng", :null => false t.integer "mappable_id" t.string "mappable_type" t.string "type" #country, city, administrative area, metro station or address end Final geo location is address it contains all neccessary information to put marker of the real estate ad on the map. But i'm still stuck on search functionality. Any help would be highly appreciated.

  • HTML input not working correctly with AJAX update panels used else where on page

    - by Sean P
    I have some update panels on my page that do some asyncpostbacks to keep some dropdownlists correctly populated. My problem is that on my page i have an HTML input that is handling some file uploads. With the AJAX on the page with asyncpostbacks, and while i step through my code behind, the files arent being uploaded. Using a postbacktrigger (non-async) is not possible because of my layout. Here is my code: <div id="divFileInputs" runat="server"> <input id="file1" name="fileInput" type="file" runat="server" size="50" style="width: 50em" onfocus="AddFileInput()" class="textbox" /></div> <select id="selectFileList" name="ListBox1" size="5" style="width: 50em; text-align: left;" class="textbox" /> <input id="RemoveAttachmentButton" type="button" value="Remove" onclick="RemoveFileInput()" class="removebutton " /> </div> Here is my code behind: Protected Sub CopyAttachments(ByVal issueId As String) Dim files As HttpFileCollection = Request.Files Dim myStream As System.IO.Stream Dim service As New SubmitService.Service For i As Integer = 0 To files.Count - 1 Dim postedFile As HttpPostedFile = files(i) Dim fileNameWithoutPath As String = System.IO.Path.GetFileName(postedFile.FileName) If fileNameWithoutPath.Length > 0 And issueId.Length > 0 Then Dim fileLength As Integer = postedFile.ContentLength Dim fileContents(fileLength) As Byte ' Read the file into the byte array. Send it to the web service. myStream = postedFile.InputStream myStream.Read(fileContents, 0, fileLength) service.ClearQuestAttachToIssue(issueId, fileNameWithoutPath, fileContents) End If Next service = Nothing End Sub When I put a breakpoint in at the declaration of service and then check the value of "files", the count is 0. I am expecting it to be 2 when i have one file uploaded. Anyone know how to fix this?

  • how to change type of value in an php array and sorting it..is it possible ?

    - by justjoe
    hi, i got problem with my code and hopefully someone able to figure it out. The main purpose is to sort array based on its value (then reindex its numerical key). i got this sample of filename : $filename = array("index 198.php", "index 192.php", "index 144.php", "index 2.php", "index 1.php", "index 100.php", "index 111.php"); $alloutput = array(); //all of index in array foreach ($filename as $name) { preg_match('#(\d+)#', $name, $output); // take only the numerical from file name array_shift($output); // cleaned. the last code create duplicate numerical in $output, if (is_array($hasilku)) { $alloutput = array_merge($alloutput, $output); } } //try to check the type of every value in array foreach ($alloutput as $output) { if (is_array($hasil)) { echo "array true </br>"; } elseif (is_int($hasil)) { echo "integer true </br>"; } elseif (is_string($hasil)) { //the numerical taken from filename always resuld "string". echo "string true </br>"; } } the output of this code will be : Array ( [0] = 198 [1] = 192 [2] = 144 [3] = 2 [4] = 1 [5] = 100 [6] = 111 ) i have test every output in array. It's all string (and not numerical), So the question is how to change this string to integer, so i can sort it from the lowest into the highest number ? the main purpose of this code is how to output array where it had been sort from lowest to highest ?

  • Loading data from file to Vector structure

    I'm trying to parse through fixed-width formatted file extracting x,y values of points from it, and then storing them in int[] array inside a Vector. Text file looks as follows : 0006 0015 0125 0047 0250 0131 That's the code : Vector<int[]> vc = new Vector<int[]>(); try { BufferedReader file = new BufferedReader(new FileReader("myfile.txt")); String s; int[] vec = new int[2]; while ((s = file.readLine()) != null) { vec[0] = Integer.parseInt(s.substring(0, 4).trim()); vec[1] = Integer.parseInt(s.substring(5, 8).trim()); vc.add(vec); } file.close(); } catch (IOException e) { } for(int i=0; i<vc.size(); i++){ for(int j=0; j<2; j++){ System.out.println(vc.elementAt(i)[j]); } } But the output shows only last line. 250 131 250 131 250 131 Should I somehow use Vector.nextElement() here to get all my data ?

  • Adding up fractions in PHP

    - by Gamemorize
    I would like to create a loop that keeps adding a set fraction, here in my example 1/3, and which later I can check against for matches with integer values. Obviously when php adds 1/3 + 1/3 + 1/3 the result is 0.9999999, so i thought I could use the occasional round to help me, but this isn't working either. The idea that I had would be that .333 + .333 becomes .666 and that if rounded that would become .667, then + .333 and the result is 1. However round only seems to work, for me, if the number of digits actually decreases. so round (0.666, 3) remains 0.666 <?php $denom = 3; $frac = 1/$denom; $frac = round($frac,3); $value = 0; $max =24; for($f = 1; $f <= $max; $f++){ echo "old value is now at ".$value.".<br/>"; $value = $value+$frac; echo "value is now at ".$value.".<br/>"; $value = round($value,3); echo "rounded value is now at ".$value.".<br/>"; $valueArray[$f] = $value; //and here for ease of testing.... if (($value==1)OR ($value==2)OR ($value==3)OR ($value==4)OR ($value==5)OR ($value==6)OR ($value==7)OR ($value==8)){ echo "match!<br/>"; }else{ echo "no match!<br/>"; } } ?> Am I going about this in a totally stupid way? Accuracy when the value is not an integer is not needed, just that it can == with integers.

  • Questions on Juval Lowy's IDesign C# Coding Standard

    - by Jan
    We are trying to use the IDesign C# Coding standard. Unfortunately, I found no comprehensive document to explain all the rules that it gives, and also his book does not always help. Here are the open questions that remain for me (from chapter 2, Coding Practices): No. 26: Avoid providing explicit values for enums unless they are integer powers of 2 No. 34: Always explicitly initialize an array of reference types using a for loop No. 50: Avoid events as interface members No. 52: Expose interfaces on class hierarchies No. 73: Do not define method-specific constraints in interfaces No. 74: Do not define constraints in delegates Here's what I think about those: I thought that providing explicit values would be especially useful when adding new enum members at a later point in time. If these members are added between other already existing members, I would provide explicit values to make sure the integer representation of existing members does not change. No idea why I would want to do this. I'd say this totally depends on the logic of my program. I see that there is alternative option of providing "Sink interfaces" (simply providing already all "OnXxxHappened" methods), but what is the reason to prefer one over the other? Unsure what he means here: Could this mean "When implementing an interface explicitly in a non-sealed class, consider providing the implementation in a protected virtual method that can be overridden"? (see Programming .NET Components 2nd Edition, end of chapter “Interfaces and Class Hierarchies”). I suppose this is about providing a "where" clause when using generics, but why is this bad on an interface? I suppose this is about providing a "where" clause when using generics, but why is this bad on a delegate?

  • How do I insert null fields with Perl's DBD::Pg?

    - by User1
    I have a Perl script inserting data into Postgres according to a pipe delimited text file. Sometimes, a field is null (as expected). However, Perl makes this field into an empty string and the Postgres insert statement fails. Here's a snippet of code: use DBI; #Connect to the database. $dbh=DBI-connect('dbi:Pg:dbname=mydb','mydb','mydb',{AutoCommit=1,RaiseError=1,PrintError=1}); #Prepare an insert. $sth=$dbh-prepare("INSERT INTO mytable (field0,field1) SELECT ?,?"); while (<){ #Remove the whitespace chomp; #Parse the fields. @field=split(/\|/,$_); print "$_\n"; #Do the insert. $sth-execute($field[0],$field[1]); } And if the input is: a|1 b| c|3 EDIT: Use this input instead. a|1|x b||x c|3|x It will fail at b|. DBD::Pg::st execute failed: ERROR: invalid input syntax for integer: "" I just want it to insert a null on field1 instead. Any ideas? EDIT: I simplified the input at the last minute. The old input actually made it work for some reason. So now I changed the input to something that will make the program fail. Also note that field1 is a nullable integer datatype.

    During the qualification round, the following question was asked: You've been given a list of words to study and memorize. Being a diligent student of language and the arts, you've decided to not study them at all and instead make up pointless games based on them. One game you've come up with is to see how you can concatenate the words to generate the lexicographically lowest possible string. Input As input for playing this game you will receive a text file containing an integer N, the number of word sets you need to play your game against. This will be followed by N word sets, each starting with an integer M, the number of words in the set, followed by M words. All tokens in the input will be separated by some whitespace and, aside from N and M, will consist entirely of lowercase letters. Output Your submission should contain the lexicographically shortest strings for each corresponding word set, one per line and in order.

  • How to get attributes values separately for each container present on the webpage in jquery ?

    - by Rachel
    This question is in continuation to How to get attributes of container in jquer, I have different containers on my webpage and all of them have <div id = "some values"> now how can I get attributes values separately for each component ? Is there any way I can know which attribute id belong to which container div ? Currently I am using : var id = $( '.promotion' ).attr( 'id' ); But if I have multiple promotional components on page and all have same div attribute as id than how can I relate that this particular attribute id belonged to this specific container ? Update: I am having a function which is called for each container present on the page and so if I am using above mentioned code than will it not always return me the first match for id in the div and would never go to other divs and so I will always get same value for id which is for the first container ? If so than what is the work around for this ? Hope this question is clear.

  • Getting a "for each" loop in Java to run in different order everytime

    - by R Stokes
    Hi, Basically my problem is that I'm trying to write a method that finds a random path in a graph of strings, which takes as it's parameters a start string, an integer length and a Vector of strings that will store the path. I'm attempting to do this by first adding the starting string to our blank vector, recursing through its neighbors until the vector's length (not including the start node) is the same as the integer length specified in the parameters. I've provided my code so far here: public Vector<String> findRandomPathFrom(String n, int len, Vector<String> randomPath){ randomPath.add(n); if (randomPath.size() == len + 1) return randomPath; for (String m : this.neighbours(n)){ if (!randomPath.contains(m) && findRandomPathFrom(m, len, randomPath) != null) return randomPath; } path.setSize(path.size() - 1); return null; } It seems to be working fine, returning a path with exactly the number of strings specified after the given start string. However, for any given starting string it generates the EXACT same path everytime, which kind of defeats the purpose of it being a random path generator. I'm guessing this problem is related to my "for each" loop, which loops through all the neighbouring strings of your current string. It seems to just be going with the first string in the neighbours vector every single time. Can anyone help me fix this problem so that it will choose a random neighbour instead of going in order? tl;dr - Any way of getting a "for each" loop in java to process a collection in a random order as oppoosed to start-to-finsih? Thanks in advance

  • VS2008 Link Error Using SafeInt3.hpp in 64bit mode.

    - by photo_tom
    I have the below code that links and runs fine in 32bit mode - #include "safeint3.hpp" typedef SafeInt<SIZE_T> SAFE_SIZE_T; SAFE_SIZE_T sizeOfCache; SAFE_SIZE_T _allocateAmt; Where safeint3.hpp is current version that can be found on Codeplex SafeInt. For those who are unaware of it, safeint is a template class that makes working with different integer types and sizes "safe". To quote channel 9 video on software - "it writes the code that you should". Which is my case. I have a class that is managing a large in-memory cache of objects (6gb) and I am very concerned about making sure that I don't have overflow/underflow issues on my pointers/sizes/other integer variables. In this use, it solves many problems. My problem is coming when moving from 32bit dev mode to 64bit production mode. When I build the app in this mode, I'm getting the following linker warnings - 1>cachecontrol.obj : warning LNK4006: "bool __cdecl IntrinsicMultiplyUint64(unsigned __int64 const &,unsigned __int64 const &,unsigned __int64 *)" (?IntrinsicMultiplyUint64@@YA_NAEB_K0PEA_K@Z) already defined in ImageInRamCache.obj; second definition ignored 1>cachecontrol.obj : warning LNK4006: "bool __cdecl IntrinsicMultiplyInt64(__int64 const &,__int64 const &,__int64 *)" (?IntrinsicMultiplyInt64@@YA_NAEB_J0PEA_J@Z) already defined in ImageInRamCache.obj; second definition ignored While I understand I can ignore the error, I would like either (a) prevent the warning from occurring or (b) make it disappear so that my QA department doesn't flag it as a problem. And after spending some time researching it, I cannot find a way to do either.

  • Spring MVC: Where to place validation and how to validation entity references.

    - by arrages
    Let's say I have the following command bean for creating a user: public class CreateUserCommand { private String userName; private String email; private Integer occupationId; pirvate Integer countryId; } occupationId and countryId are drop down selected values on the form. They map to an entity in the database (Occupation, Country). This command object is going to be fed to a service facade like so: userServiceFacade.createUser(CreateUserCommand command); This facade will construct a user entity to be sent to the actual service. So I suppose that in the facade layer I will have to make several dao calls to map all the lookup properties of the User entity. Based on this what is the best strategy to validate that occupationId and countryId map to real entities? Where is the best place to perform this validation? There is the spring validator but I am not sure this is the best place for this, for one I am wary of this method as validation is tied to the web tier, but also that means I would need to make the dao calls in the validator for validation but I would need to call the dao's in the facade layer again when the command - entity translation occurs. Is there anything I can do better? Thanks.

  • Delphi - Clean TListBox Items

    - by Brad
    I want to clean a list box by checking it against two other list boxes. Listbox1 would have the big list of items Listbox2 would have words I want removed from listbox1 Listbox3 would have mandatory words that have to exist for it to remain in listbox1 Below is the code I've got so far for this, it's VERY slow with large lists. // not very efficient Function checknegative ( instring : String; ListBox : TListBox ) : Boolean; Var i : Integer; Begin For I := listbox.Items.Count - 1 Downto 0 Do Begin If ExistWordInString ( instring, listbox.Items.Strings [i], [soWholeWord, soDown] ) = True Then Begin result := True; //True if in list, False if not. break; End Else Begin result := False; End; End; result:=false; End; Function ExistWordInString ( aString, aSearchString : String; aSearchOptions : TStringSearchOptions ) : Boolean; Var Size : Integer; Begin Size := Length ( aString ); If SearchBuf ( Pchar ( aString ), Size, 0, 0, aSearchString, aSearchOptions ) <> Nil Then Begin result := True; End Else Begin result := False; End; End;

  • Grouping arrays with consecutive keys

    - by KPL
    Hello people, I've an array like this - Array ( [16] => 424 [17] => 404 [18] => 416 [21] => 404 [22] => 456 [23] => 879 [28] => 456 [29] => 456 [32] => 123 [35] => 465 ) The output of this array would be Array ( [0] => Array ( ['start'] => 16 ['stop'] => 18 ) [1] => Array ( ['start'] => 21 ['stop'] => 23 ) [2] => Array ( ['start'] => 28 ['stop'] => 29 ) [3] => Array ( ['start'] => 32 ['stop'] => 33 ) [4] => Array ( ['start'] => 35 ['stop'] => 36 ) ) I don't really need the values. Just grouping the keys. And if consecutive integer doesn't exist for a particular key(like for [32] and [35]), 'stop' should be the consecutive integer. Thank you all for help.

  • Grails one-to-many mapping with joinTable

    - by intargc
    I have two domain-classes. One is a "Partner" the other is a "Customer". A customer can be a part of a Partner and a Partner can have 1 or more Customers: class Customer { Integer id String name static hasOne = [partner:Partner] static mapping = { partner joinTable:[name:'PartnerMap',column:'partner_id',key:'customer_id'] } } class Partner { Integer id static hasMany = [customers:Customer] static mapping = { customers joinTable:[name:'PartnerMap',column:'customer_id',key:'partner_id'] } } However, whenever I try to see if a customer is a part of a partner, like this: def customers = Customer.list() customers.each { if (it.partner) { println "Partner!" } } I get the following error: org.springframework.dao.InvalidDataAccessResourceUsageException: could not execute query; SQL [select this_.customer_id as customer1_162_0_, this_.company as company162_0_, this_.display_name as display3_162_0_, this_.parent_customer_id as parent4_162_0_, this_.partner_id as partner5_162_0_, this_.server_id as server6_162_0_, this_.status as status162_0_, this_.vertical_market as vertical8_162_0_ from Customer this_]; nested exception is org.hibernate.exception.SQLGrammarException: could not execute query It looks as if Grails is thinking partner_id is a part of the Customer query, and it's not... It is in the PartnerMap table, which is supposed to find the customer_id, then get the Partner from the corresponding partner_id. Anyone have any clue what I'm doing wrong? Edit: I forgot to mention I'm doing this with legacy database tables. So I have a Partner, Customer and PartnerMap table. PartnerMap has simply a customer_id and partner_id field.

  • symfony + doctrine + inheritance, how to make them work?

    - by imac
    I am beginning to work with Symfony, I've found some documentation about inheritance. But also found this discouraging article, which make me doubt if Doctrine handles inheritance any good at all... Has anyone find a smart solution for inheritance in Symfony+Doctrine? As an example, I have already structured the database something like this: CREATE TABLE `poster` ( `poster_id` int(11) NOT NULL AUTO_INCREMENT, `user_name` varchar(50) NOT NULL, PRIMARY KEY (`poster_id`), UNIQUE KEY `id` (`poster_id`), ) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=latin1; CREATE TABLE `user` ( `user_id` int(11) NOT NULL, `real_name` varchar(50) DEFAULT NULL, PRIMARY KEY (`user_id`), UNIQUE KEY `user_id` (`user_id`), CONSTRAINT `user_fk` FOREIGN KEY (`user_id`) REFERENCES `poster` (`poster_id`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1; From that, Doctrine generated this "schema.yml": Poster: connection: doctrine tableName: poster columns: poster_id: type: integer(4) fixed: false unsigned: false primary: true autoincrement: true user_name: type: string(50) fixed: false unsigned: false primary: false notnull: true autoincrement: false relations: Post: local: poster_id foreign: poster_id type: many User: local: poster_id foreign: user_id type: many Version: local: poster_id foreign: poster_id type: many User: connection: doctrine tableName: user columns: user_id: type: integer(4) fixed: false unsigned: false primary: true autoincrement: false real_name: type: string(50) fixed: false unsigned: false primary: false notnull: false autoincrement: false relations: Poster: local: user_id foreign: poster_id type: one User creation for this structure with Doctrine auto-generated forms does not work. Any clue will be appreciated.
