  • Modelling deterministic and nondeterministic data separately

    - by Superstringcheese
    I'm working with the Microsoft ADO.NET Entity Framework for a game project. Following the advice of other posters on SO, I'm considering modelling deterministic and nondeterministic data separately. The idea for this came from a discussion on multiplayer games, but it seemed to make sense in a single-player scenario as well. Deterministic (things that aren't going to change during gameplay) Attributes (Strength, Agility, etc.) and their descriptions Skills and their descriptions and requirements Races, Factions, Equipment, etc. Base Attribute/Skill/Equipment loadouts for monsters Nondeterministic (things that will change a lot during gameplay) Beings' current AttributeModifers (Potion of Might = +10 Strength), current health and mana, etc. Player inventory, cash, experience, level Player quests states Player FactionRelationships ...and so on. My deterministic model would serve as a set of constants. My nondeterministic model would provide my on-the-fly operable data and would be serialized to a savegame file to maintain game state between play sessions. The data store will be an embedded SQL Compact database. So I might want to create relations between my Attributes table (deterministic model) and my BeingAttributeModifiers table (nondeterministic model), but how do I set that up across models? Det model/db Nondet model/db ____________ ________________________ |Attributes | |PlayerAttributeModifiers| |------------| |------------------------| |Id | |Id | |Name | |AttributeId | |Description | |SourceId | ------------ |Value | ------------------------ Should I use two separate models (edmx) that transact with a single database containing both deterministic-type and nondeterministic-type tables? Or should/can I use two separate databases in one model? Or two models each with their own database? With distinct models/dbs it seems like this will get really complicated and I'll end up fighting EF a lot, rolling my own transaction code, and generally losing out on a lot of the advantages of the framework. I know these are vague questions, I'm just looking for a sanity check before I forge ahead any further.

  • SQL Query to duplicate records based on If statement

    - by user328371
    Hi, I'm trying to write an SQL query that will duplicate records depending on a field in another table. I am running mySQL 5. (I know duplicating records shows that the database structure is bad, but I did not design the database and am not in a position to redo it all - it's a shopp ecommerce database running on wordpress.) Each product with a particular attribute needs a link to the same few images, so the product will need a row per image in a table - the database doesn't actually contain the image, just its filename. (the images are of clipart for a customer to select from) Based on these records... SELECT * FROM `wp_shopp_spec` WHERE name='Can Be Personalised' and content='Yes' I want to do something like this.. For each record that matches that query, copy records 5134 - 5139 from wp_shopp_asset but change the id so it's unique and set the cell in column 'parent' to have the value of 'product' from the table wp_shopp_spec. This will mean 6 new records are created for each record matching the above query, all with the same value in 'parent' but with unique ids and every other column copied from the original (ie. records 5134-5139) Hope that's clear enough - any help greatly appreciated.

  • C# How can I return my base class in a webservice

    - by HenriM
    I have a class Car and a derived SportsCar: Car Something like this: public class Car { public int TopSpeed{ get; set; } } public class SportsCar : Car { public string GirlFriend { get; set; } } I have a webservice with methods returning Cars i.e: [WebMethod] public Car GetCar() { return new Car() { TopSpeed = 100 }; } It returns: <Car> <TopSpeed>100</TopSpeed> </Car> I have another method that also returns cars like this: [WebMethod] public Car GetMyCar() { Car mycar = new SportsCar() { GirlFriend = "JLo", TopSpeed = 300 }; return mycar; } It compiles fine and everything, but when invoking it I get: System.InvalidOperationException: There was an error generating the XML document. --- System.InvalidOperationException: The type wsBaseDerived.SportsCar was not expected. Use the XmlInclude or SoapInclude attribute to specify types that are not known statically. I find it strange that it can't serialize this as a straight car, as mycar is a car. Adding XmlInclude on the WebMethod of ourse removes the error: [WebMethod] [XmlInclude(typeof(SportsCar))] public Car GetMyCar() { Car mycar = new SportsCar() { GirlFriend = "JLo", TopSpeed = 300 }; return mycar; } and it now returns: <Car xsi:type="SportsCar"> <TopSpeed>300</TopSpeed> <GirlFriend>JLo</GirlFriend> </Car> But I really want the base class returned, without the extra properties etc from the derived class. Is that at all possible without creating mappers etc? Please say yes ;)

  • Is there a way to parse XML via SAX/DOM with line numbers available per node.

    - by Chris
    I already have written a DOM parser for a large XML document format that contains a number of items that can be used to automatically generate Java code. This is limited to small expressions that are then merged into a dynamically generated Java source file. So far - so good. Everything works. BUT - I wish to be able to embed the line number of the XML node where the Java code was included from (so that if the configuration contains uncompilable code, each method will have a pointer to the source XML document and the line number for ease of debugging). I don't require the line number at parse-time and I don't need to validate the XML Source Document and throw an error at a particular line number. I need to be able to access the line number for each node and attribute in my DOM or per SAX event. Any suggestions on how I might be able to achieve this? P.S. Also, I read the StAX has a method to obtain line number whilst parsing, but ideally I would like to achieve the same result with regular SAX/DOM processing in Java 4/5 rather than become a Java 6+ application or take on extra .jar files.

  • Grails g:paginate tag and custom URL

    - by aboxy
    Hello, I am trying to use g:paginate in a shared template where depending on the controller, url changes e.g. For my homepage url should be : mydomain[DOT]com/news/recent/(1..n) For search Page: www[DOT]mydomain[DOT]com/search/query/"ipad apps"/filter/this month and my g:paginate looks like this: g:paginate controller=${customeController} action=${customAction} total:${total} For the first case, I was able to provide controller as 'news' and action as 'recent' and mapped url /news/recent/$offset to my controller. But for the search page, I am not able to achieve what I want to do. I have a URL mapping defined as /search/$filter**(controller:"search",action:"fetch") $filter can be /query/"ipad apps"/filter/thismonth/filter/something/filter/somethingelse. I want to be able to show the url as above rather than ?query="ipad apps"&filter=thismonth&filter=something&filter=somethingelse. I believe I can pass all the parameters in params attribute of g:paginate but that will not give me pretty URL. What would be the best way to achieve this? Please feel free to ask questions If i missed anything.Thanks in advance.

  • Is it possible to order by a composite key with JPA and CriteriaBuilder

    - by Kjir
    I would like to create a query using the JPA CriteriaBuilder and I would like to add an ORDER BY clause. This is my entity: @Entity @Table(name = "brands") public class Brand implements Serializable { public enum OwnModeType { OWNER, LICENCED } @EmbeddedId private IdBrand id; private String code; //bunch of other properties } Embedded class is: @Embeddable public class IdBrand implements Serializable { @ManyToOne private Edition edition; private String name; } And the way I am building my query is like this: CriteriaBuilder cb = em.getCriteriaBuilder(); CriteriaQuery<Brand> q = cb.createQuery(Brand.class).distinct(true); Root<Brand> root = q.from(Brand.class); if (f != null) { f.addCriteria(cb, q, root); f.addOrder(cb, q, root, sortCol, ascending); } return em.createQuery(q).getResultList(); And here are the functions called: public void addCriteria(CriteriaBuilder cb, CriteriaQuery<?> q, Root<Brand> r) { } public void addOrder(CriteriaBuilder cb, CriteriaQuery<?> q, Root<Brand> r, String sortCol, boolean ascending) { if (ascending) { q.orderBy(cb.asc(r.get(sortCol))); } else { q.orderBy(cb.desc(r.get(sortCol))); } } If I try to set sortCol to something like "id.edition.number" I get the following error: javax.ejb.EJBException: java.lang.IllegalArgumentException: Unable to resolve attribute [id.name] against path Any idea how I could accomplish that? I tried searching online, but I couldn't find a hint about this... Also would be great if I could do a similar ORDER BY when I have a @ManyToOne relationship (for instance, "id.edition.number")

  • Change with jQuery a cell of a table created with JSF

    - by perissf
    From within a xhtml page created with JSF, I need to use JavaScript / jQuery for changing the content of a cell of a table. I know how to assign a unique id to the div containing the table, and to the tbody. I can also assign unique class names to the div itself and to the target column. The target row is identified by the data-rk attribute. <div id="tabForm:centerTabView:personsTable" class="ui-datatable ui-widget personsTable"> <table role="grid"> <tbody id="tabForm:centerTabView:personsTable_data" > <tr data-rk="2" > <td ... /> <td class="lastNameCol" role="gridcell"> <div> To Be Edited </div> </td> <td ... /> </tr> <tr ... /> </tbody> </table> </div> I have tried with many combinations of different jQuery selectors, but I am really lost. I need to search my target row and my target column inside that particular div or inside that particular table, because the xhtml page may contain other tables with different unique ids (and accidentally with the same row and column ids).

  • PHP: Post ASPX form that uses 'WebForm_DoPostBackWithOptions' with cUrl

    - by Oliver Cooper
    I am trying to post an ASPX form which uses SharePoint with PHP. Posting data works with standard forms, I just can't seem to get this form working. I did notice an onclick attribute on the submit button: onclick="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("ctl00$PlaceHolderMain$btnSaveTask", "", true, "", "", false, false))" I have never used ASPX and have no idea what this is. It is not an authentication problem or something wrong with the url as it returns the webpage (which contains the form) fine. Here is my PHP code: function add($username, $password){ $data = array( 'ctl00$PlaceHolderSearchArea$ctl01$ctl00' => 'https://keystone.stpeters.sa.edu.au', 'ctl00$PlaceHolderSearchArea$ctl01$ctl04' => '0', 'ctl00$PlaceHolderMain$DateStart$DateStartDate' => '9/05/2012', 'ctl00$PlaceHolderMain$DateDue$DateDueDate' => '10/05/2012', 'ctl00$PlaceHolderMain$Title' => 'test again', 'ctl00$PlaceHolderMain$btnSaveTask' => 'OK', '__spText1' => '', '__spText2' => '' ); $curl_handle = curl_init(); $fullurl = "https://keystone.stpeters.sa.edu.au/_layouts/StPeters.Keystone/MyTasks/MyTaskDetail.aspx?id=0&IsDlg=1"; // $ch = curl_init(); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_VERBOSE, 1); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, $data); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); curl_setopt($ch, CURLOPT_FAILONERROR, 0); curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY); curl_setopt($ch, CURLOPT_USERPWD, "$username:$password"); curl_setopt($ch, CURLOPT_URL, $fullurl); $returned = curl_exec($ch); curl_close ($ch); return $returned; }

  • EJB and JPA and @OneToMany - Transaction too long?

    - by marioErr
    Hello. I'm using EJB and JPA, and when I try to access PhoneNumber objects in phoneNumbers attribute of Contact contact, it sometimes take several minutes for it to actually return data. It just returns no phoneNumbers, not even null, and then, after some time, when i call it again, it magically appears. This is how I access data: for (Contact c : contactFacade.findAll()) { System.out.print(c.getName()+" "+c.getSurname()+" : "); for (PhoneNumber pn : c.getPhoneNumbers()) { System.out.print(pn.getNumber()+" ("+pn.getDescription()+"); "); } } I'm using facade session ejb generated by netbeans (basic CRUD methods). It always prints correct name and surname, phonenumbers and description are only printed after some time (it varies) from creating it via facade. I'm guessing it has something to do with transactions. How to solve this? These are my JPA entities: contact @Entity public class Contact implements Serializable { private static final long serialVersionUID = 1L; @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id; private String name; private String surname; @OneToMany(cascade = CascadeType.REMOVE, mappedBy = "contact") private Collection<PhoneNumber> phoneNumbers = new ArrayList<PhoneNumber>(); phonenumber @Entity public class PhoneNumber implements Serializable { private static final long serialVersionUID = 1L; @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id; private String number; private String description; @ManyToOne() @JoinColumn(name="CONTACT_ID") private Contact contact;

  • Styling individual radio buttons in drupal form

    - by Andrew
    I have this group of radio buttons in which each of individual button has of its own position set through style attribute. I would like to how can I archive the same by using drupal form api. I found how to style as whole but, not as individual control within group. Here's how my html code look like - <input type="radio" name="base_location" checked="checked" value="0" style="margin-left:70px;float:left;"/><span style="float:left;">District</span> <input type="radio" name="base_location" value="1" style="margin-left:50px;float:left;"/><span style="float:left;">MRT</span> <input type="radio" name="base_location" value="2" style="margin-left:60px;float:left;"/><span style="float:left;">Address</span> And this is the drupal code I'm stuck at - $form['base_location'] = array( '#type' => 'radios', '#title' => t('base location'), '#default_value' => variable_get('search_type', 0), '#options' => array( '0'=>t('District'), '1'=>t('MRT'), '2'=>t('Address')), '#description' => t('base location'), I'm aware of #type=radio existence. However, I do not know how to group all my radio buttons together in this regard. If I use same array key for all of them, they would collide each other. If I don't, they aren't seen as part of the same group. I thank you in advance.

  • Why is Core Data not persisting these changes to disk?

    - by scott
    I added a new entity to my model and it loads fine but no changes made in memory get persisted to disk. My values set on the car object work fine in memory but aren't getting persisted to disk on hitting the home button (in simulator). I am using almost exactly the same code on another entity in my application and its values persist to disk fine (core data - sqlite3); Does anyone have a clue what I'm overlooking here? Car is the managed object, cars in an NSMutableArray of car objects and Car is the entity and Visible is the attribute on the entity which I am trying to set. Thanks for you assistance.

  • How do I serialize an enum value as an int?

    - by Espo
    I want to serialize my enum-value as an int, but i only get the name. Here is my (sample) class and enum: public class Request { public RequestType request; } public enum RequestType { Booking = 1, Confirmation = 2, PreBooking = 4, PreBookingConfirmation = 5, BookingStatus = 6 } And the code (just to be sure i'm not doing it wrong) Request req = new Request(); req.request = RequestType.Confirmation; XmlSerializer xml = new XmlSerializer(req.GetType()); StringWriter writer = new StringWriter(); xml.Serialize(writer, req); textBox1.Text = writer.ToString(); This answer (to another question) seems to indicate that enums should serialize to ints as default, but it doesn't seem to do that. Here is my output: <?xml version="1.0" encoding="utf-16"?> <Request xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <request>Confirmation</request> </Request> I have been able to serialize as the value by putting an "[XmlEnum("X")]" attribute on every value, but this just seems wrong.

  • Using JQuery to traverse DOM structure, finding a specific <table> element located after HTML 'comme

    - by Shadow
    I currently have a website source code (no control over the source) which contains certain content that needs to be manipulated. This would be simple on the surface, however there is no unique ID attribute on the tag in question that can uniquely identify it, and therefore allow for further traversal. Here is a snippet of the source code, surrounding the tag in question. ... <td width="100%"> <!--This table snaps the content columns(one or two)--> <table border="0" width="100%"> ... Essentially, the HTML comment stuck out as an easy way to gain access to that element. Using the JQuery comment add-on from this question, and some help from snowlord comment below, I have been able to identify the comment and retrieve the following output using the 'dump' extension. $('td').comments().filter(":contains('This table snaps the content columns(one or two)')").dump(); returns; jQuery Object { 0 = DOMElement [ nodeName: DIV nodeValue: null innerHTML: [ 0 = String: This table snaps the content columns(one or two) ] ] } However I am not sure how to traverse to the sibling element in the DOM. This should be simple, but I haven't had much selector experience with JQuery. Any suggestions are appreciated.

  • Stack Overflow problem transforming with a custom xslt

    - by Flynn1179
    I've got a system that allows the user the option of providing their own XSLT to apply to some data that's been retrieved, as a means of specifying how that data should be presented. However, if the user includes code in the XSLT equivalent to: <xsl:template match="/"> <xsl:element name="data"> <xsl:apply-templates select="." /> </xsl:element> </xsl:template> this causes .NET to infinitely recurse trying to process it, and produces a stack overflow error. I need to be able to trap this before it crashes the app, as the data that's been retrieved is occasionally quite time-consuming to obtain, and the data is lost when this happens. Is there any way of doing this? I know it's theoretically possible to identify any occurrences of xsl:apply-templates with "." in the select attribute, but this isn't the only way an infinite recursion could happen, I need a way of generically trapping it.

  • Dynamically setting the queryset of a ModelMultipleChoiceField to a custom recordset

    - by Daniel Quinn
    I've seen all the howtos about how you can set a ModelMultipleChoiceField to use a custom queryset and I've tried them and they work. However, they all use the same paradigm: the queryset is just a filtered list of the same objects. In my case, I'm trying to get the admin to draw a multiselect form that instead of using usernames as the text portion of the , I'd like to use the name field from my account class. Here's a breakdown of what I've got: # models.py class Account(models.Model): name = models.CharField(max_length=128,help_text="A display name that people understand") user = models.ForeignKey(User, unique=True) # Tied to the User class in settings.py class Organisation(models.Model): administrators = models.ManyToManyField(User) # admin.py from django.forms import ModelMultipleChoiceField from django.contrib.auth.models import User class OrganisationAdminForm(forms.ModelForm): def __init__(self, *args, **kwargs): from ethico.accounts.models import Account self.base_fields["administrators"] = ModelMultipleChoiceField( queryset=User.objects.all(), required=False ) super(OrganisationAdminForm, self).__init__(*args, **kwargs) class Meta: model = Organisation This works, however, I want queryset above to draw a selectbox with the Account.name property and the User.id property. This didn't work: queryset=Account.objects.all().order_by("name").values_list("user","name") It failed with this error: 'tuple' object has no attribute 'pk' I figured that this would be easy, but it's turned into hours of dead-ends. Anyone care to shed some light?

  • FindWindowEx from user32.dll is returning a handle of Zero and error code of 127 using dllimport

    - by puretechy
    I need to handle another windows application programatically, searching google I found a sample which handles windows calculator using DLLImport Attribute and importing the user32.dll functions into managed ones in C#. The application is running, I am getting the handle for the main window i.e. Calculator itself, but the afterwards code is not working. The FindWindowEx method is not returning the handles of the children of the Calculator like buttons and textbox. I have tried using the SetLastError=True on DLLImport and found that I am getting an error code of 127 which is "Procedure not found". This is the link from where I got sample application: http://www.codeproject.com/script/Articles/ArticleVersion.aspx?aid=14519&av=34503 Please help if anyone knows how to solve it. UPDATE: The DLLImport is: [DllImport("user32.dll", SetLastError = true)] public static extern IntPtr FindWindowEx(IntPtr parentHandle, IntPtr childAfter, string className, string windowTitle); The Code that is not working is: hwnd=FindWindow(null,"Calculator"); // This is working, I am getting handle of Calculator // The following is not working, I am getting hwndChild=0 and err = 127 hwndChild = FindWindowEx((IntPtr)hwnd,IntPtr.Zero,"Button","1"); Int32 err = Marshal.GetLastWin32Error();

  • How do I get jQuery's Uploadify plugin to work with ASP.NET MVC?

    - by KingNestor
    I'm in the process of trying to get the jQuery plugin, Uploadify, to work with ASP.NET MVC. I've got the plugin showing up fine: With the following javascript snippet: <script type="text/javascript"> $(document).ready(function() { $('#fileUpload').fileUpload({ 'uploader': '/Content/Flash/uploader.swf', 'script': '/Placement/Upload', 'folder': '/uploads', 'multi': 'true', 'buttonText': 'Browse', 'displayData': 'speed', 'simUploadLimit': 2, 'cancelImg': '/Content/Images/cancel.png' }); }); </script> Which seems like all is well in good. If you notice, the "script" attribute is set to my /Placement/Upload, which is my Placement Controller and my Upload Action. The main problem is, I'm having difficulty getting this action to fire to receive the file. I've set a breakpoint on that action and when I select a file to upload, it isn't getting executed. I've tried changing the method signature based off this article: public string Upload(HttpPostedFileBase FileData) { /* * * Do something with the FileData * */ return "Upload OK!"; } But this still doesn't fire. Can anyone help me write and get the Upload controller action's signature correctly so it will actually fire? I can then handle dealing with the file data myself. I just need some help getting the method action to fire.

  • asp.net master page/content page interaction with style sheet

    - by Matt
    Learning how to do a master page in asp.net. Trying to figure out how my style sheet interacts with respects to the master page and content page. I can get HTML tags like body and the style sheet to react. But when I call the ID attribute of a label no styling takes place. What am I missing here as far as interaction? BTW I'm using VS2008 CSS sample: body { height:1200px; width:920px; border-style:solid; border-color:blue; padding:10px 10px 10px 10px; } #toptext1 { position:relative; top:-225px; right:-500px; font-size:22px; font-weight:bold; } From the master page: <body> <form id="form1" runat="server"> <asp:image id="cookNookLogo" ImageUrl="images/Logo.gif" runat="server" AlternateText="CookNook" Width="449px"></asp:image> <p> <asp:Label ID="toptext1" runat="server" Text="Quality Recipes, Hints and Supplies"></asp:Label> </p> From the content page: <%@ Page Language="C#" MasterPageFile="~/CNMasterPage.master" AutoEventWireup="true" CodeFile="Home.aspx.cs" Inherits="Home" Title="Untitled Page" %> <asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server"> <link href="App_Themes/cn/cn.css" rel="stylesheet" type="text/css" /> </asp:Content> When I was doing this without a master page it worked so where am I going wrong with the attributes?

  • RichFaces a4j:support parameter passing

    - by Mark Lewis
    Hello I have a number of rich:inplaceInput tags in RichFaces which represent numbers in an array. The validator allows integers only. When a user clicks in an input and changes a value, how can I get the bean to sort the array given the new number and reRender the list of rich:inplaceInput tags so that they're in numerical order? EG <a4j:region> <rich:dataTable value="#{MyBacking.config}" var="feed" cellpadding="0" cellspacing="0" width="100%" border="0" columns="5" id="Admin"> ... <a4j:repeat... <a4j:region id="MsgCon"> <rich:inplaceInput value="#{h.id}" validator="#{MyBacking.validateID}" id="andID" showControls="true"> <a4j:support event="onviewactivated" action="#{MyBacking.sort}" reRender="Admin" /> </rich:inplaceInput> </a4j:region> </a4j:repeat> </data:Table> </a4j:region> Note I do NOT want to use dataTable sort functions. The table is complicated and I've specified id="Admin" (ie the whole table) to reRender as I've not found a way to send more localised values to the backing bean through the inplaceInput. This question is about how to use a4j:support action attribute to call the sort method so that when the reRender rerenders the component, it outputs the list in sorted order. I have the sort method working ok when I click a button to sort, but I want to have the list sorted automatically as soon as a new valid value is entered into the inplaceInput component. Thanks

  • pure/const functions in C++

    - by Albert
    Hi, I'm thinking of using pure/const functions more heavily in my C++ code. (pure/const attribute in GCC) However, I am curious how strict I should be about it and what could possibly break. The most obvious case are debug outputs (in whatever form, could be on cout, in some file or in some custom debug class). I probably will have a lot of functions, which don't have any side effects despite this sort of debug output. No matter if the debug output is made or not, this will absolutely have no effect on the rest of my application. Or another case I'm thinking of is the use of my own SmartPointer class. In debug mode, my SmartPointer class has some global register where it does some extra checks. If I use such an object in a pure/const function, it does have some slight side effects (in the sense that some memory probably will be different) which should not have any real side effects though (in the sense that the behaviour is in any way different). Similar also for mutexes and other stuff. I can think of many complex cases where it has some side effects (in the sense of that some memory will be different, maybe even some threads are created, some filesystem manipulation is made, etc) but has no computational difference (all those side effects could very well be left out and I would even prefer that). How does it work out in practice? If I mark such functions as pure/const, could it break anything (considering that the code is all correct)?

  • Rails: creating a custom data type, to use with generator classes and a bunch of questions related t

    - by Shyam
    Hi, After being productive with Rails for some weeks, I learned some tricks and got some experience with the framework. About 10 days ago, I figured out it is possible to build a custom data type for migrations by adding some code in the Table definition. Also, after learning a bit about floating points (and how evil they are) vs integers, the money gem and other possible solutions, I decided I didn't WANT to use the money gem, but instead try to learn more about programming and finding a solution myself. Some suggestions said that I should be using integers, one for the whole numbers and one for the cents. When playing in script/console, I discovered how easy it is to work with calculations and arrays. But, I am talking to much (and the reason I am, is to give some sufficient background). Right now, while playing with the scaffold generator (yes, I use it, because I like they way I can quickly set up a prototype while I am still researching my objectives), I like to use a DRY method. In my opinion, I should build a custom "object", that can hold two variables (Fixnum), one for the whole, one for the cents. In my big dream, I would be able to do the following: script/generate scaffold Cake name:string description:text cost:mycustom Where mycustom should create two integer columns (one for wholes, one for cents). Right now I could do this by doing: script/generate scaffold Cake name:string description:text cost_w:integer cost_c:integer I had also had an idea that would be creating a "cost model", which would hold two columns of integers and create a cost_id column to my scaffold. But wouldn't that be an extra table that would cause some kind of performance penalty? And wouldn't that be defy the purpose of the Cake model in the first place, because the costs are an attribute of individual Cake entries? The reason why I would want to have such a functionality because I am thinking of having multiple "costs" inside my rails application. Thank you for your feedback, comments and answers! I hope my message got through as understandable, my apologies for incorrect grammar or weird sentences as English is not my native language.

  • Problem: writing parameter values to data driven MSTEST output

    - by Shubh
    Hi, I am trying to extract some information about the parameter variants used in an MSTEST data driven test case from trx file. Currently, For data driven tests, I get the output of same testcase with different inputs as a sequence of tags , but there is no info about the value of the variants. Example: Suppose we have a [data driven]TestMethod1() and the data rows contain variations a and b. There are two variations a=1,b=2 for which the test passes and a=3,b=4 for which the test fails. If we can output the info that it was a=1,b=2 which passed and a=3 b=4 which failed in the trx file; the output will be meaningful. Better information about test case runs from the output file alone(without any dependencies). Investigating the test failure without rerunning the whole set If the data rows change in data source(now a=1,b=2 pass and a=5,b=6 fail) , easy to decipher that the errors are different; although the fail sequence is still the same(row 0 pass row 1 fail but now row1 is different) Has any of you gone through a similar problem? What did you follow? I tried to put the parameter value information in the Description attribute of TestMethod, it didnt work. Any other methods you think can work too? thanks, Shubhankar

  • Conditional operator in Mako using Pylons

    - by Antoine Leclair
    In PHP, I often use the conditional operator to add an attribute to an html element if it applies to the element in question. For example: <select name="blah"> <option value="1"<?= $blah == 1 ? ' selected="selected"' : '' ?>> One </option> <option value="2"<?= $blah == 2 ? ' selected="selected"' : '' ?>> Two </option> </select> I'm starting a project with Pylons using Mako for the templating. How can I achieve something similar? Right now, I see two possibilities that are not ideal. Solution 1: <select name="blah"> % if blah == 1: <option value="1" selected="selected">One</option> % else: <option value="1">One</option> % endif % if blah == 2: <option value="2" selected="selected">Two</option> % else: <option value="2">Two</option> % endif </select> Solution 2: <select name="blah"> <option value="1" % if blah == 1: selected="selected" % endif >One</option> <option value="2" % if blah == 2: selected="selected" % endif >Two</option> </select> In this particular case, the value is equal to the variable tested (value="1" = blah == 1), but I use the same pattern in other situations, like <?= isset($variable) ? ' value="$variable" : '' ?>. I am looking for a clean way to achieve this using Mako.
