  • Semicolon in object variable name

    - by milkfilk
    There's a common LDAP attribute called userCertificate;binary. It actually has a semi-colon in the attribute name. In ruby, I turn an LDAP entry into a OpenStruct object called 'struct'. struct.class = OpenStruct But of course ruby thinks it's an end-of-line character. ? struct.userCertificate;binary NameError: undefined local variable or method `binary' for main:Object from (irb):52 from :0 IRB knows that the local variable is there, because it gives me struct.userCertificate;binary from the tab auto-completion. I can also see the class variable when calling struct.methods on it. struct.methods = ... "send", "methods", "userCertificate;binary=", "hash", ... It's definitely there, I can see the contents if I print the whole variable to_s(). But how can I access the local variable when it has a semicolon in it? I have workarounds for this but I thought it was an interesting problem to post.

  • cannot convert to object

    - by Dazz
    if i execute the following code i get a cannot convert to object error; Uncaught exception: TypeError: Cannot convert 'validation.messages.field' to object $.fn.validate = function(validation) { $.each(validation.rules, function(field, fieldRules){ $.each(fieldRules, function(rule, ruleValue){ var fieldValue = $('[name=' + field + ']').val(); if (eval(rule + '(fieldValue, ruleValue)') == false){ alert(validation.rules.field.rule); return false; }else{ return true; }; }); }); } the problem is the alert(validation.messages.field.rule); 'field' = 'persoon_voornaam' and 'rule' = 'required' and validation.messages.persoon_voornaam.required works just fine. What am i doing wrong? validation is a JSON that look like this: { rules: { persoon_voornaam: { required: true, minlength: 5, }, postcode_bestemming: { required: true, minlength: 7, }, }, messages: { persoon_voornaam: { required: 'Dit veld is verplicht', minlengt: 'Dit veld moet minstens 5 lang zijn', }, } }

    - by Benedikt R.
    Hi! Can someone confirm a save process misbehaviour in the AppModel for the method beforeSave( )? This method doesn't seem to be executed before saving a data set. I can remember of reading something about a bug in a current version (btw, I am using 1.3.1). Best regards, Beendikt

  • Call to a member function query() on a non-object

    - by Randy Gonzalez
    Ok, this is so weird!!! I am running PHP Version 5.1.6 when I try and run the code below it gives a fatal error of an object that has not been instantiated. As soon as I un-comment this line of code //$cb_db = new cb_db(USER, PASSWORD, NAME, HOST); everything works. Even though I have declared the $cb_db object as global within in the method. Any help would be greatly appreciated. require_once ( ROOT_CB_CLASSES . 'db.php'); $cb_db = new cb_db(USER, PASSWORD, NAME, HOST); class cb_user { protected function find_by_sql( $sql ) { global $cb_db; //$cb_db = new cb_db(USER, PASSWORD, NAME, HOST); $result_set = $cb_db->query( $sql ); $object_array = array(); while( $row = $cb_db->fetch_array( $result_set ) ) { $object_array[] = self::instantiate( $row ); } return $object_array; } }

  • Ravendb 960 does not honor JsonIgnore with property of Dictionary<string, object>

    - by David Robbins
    Does JsonIgnore not work when a property has data? I have the followin class: public class SomeObject { public string Name { get; set; } public DateTime Created { get; set; } public List<string> ErrorList { get; set; } [JsonIgnore] public Dictionary<string, object> Parameters { get; set; } public SomeObject() { this.ErrorList = new List<string>(); this.Parameters = new Dictionary<string, object>(); } } My expectation was that JsonIgnore would exclude properties from De- / Serialization. My RavenDB document has data. Am I missing something?

  • Rails application and multilingual content, Model dilemma

    - by dakull
    I'm writing in Rails a website that will be multilingual, for the application translation part i will use the simple I18n gem, for messages and everything related. Yet, all the content must be translated, and we're talking about lots of pages, that will be stored into the database ( like articles, news, etc. ) For now, I'm thinking of two approaches: Lets say i have a Pages table, the content in diff. languages, i will be storing it in a different table called PagesContent that will belong_to Pages and also to a Languages table. The problem here, is that I'll essentially duplicate the no. of tables needed. Pros: flexibility, in the box validation To skip that duplication i can serialize a hash into the content column of Pages, containing the translation. The problem here, is validation, arguably more code to write, and less flexibility when adding a new language. Pros: Less tables. Any other idea ?

  • Unable to read values from object returned from ActiveRecord.find

    - by Venki
    I make the following call to the DB. @patientRegistration = PatientRegistration.find(:all, :conditions=["name = '#{patientName}'"]) Search for patient registration based on a given name. I get a valid @patientRegistration object.When I invoke @patientRegistration.inspect it prints correctly all the values for the object in the DB. But when I try to read a particular attribute (Say id or name) by doing the following: @patientRegistration.id or @patientRegistration.name. I get invalid values. Either its blank or some junk values. I dont understand how inspect is able to retrieve all the values correctly but reading individual attributes gives invalid values. Thanks

  • OpenGL index buffer object with additional data

    - by muksie
    I have a large set of lines, which I render from a vertex buffer object using glMultiDrawArrays(GL_LINE_STRIP, ...); This works perfectly well. Now I have lots of vertex pairs which I also have to visualize. Every pair consists of two vertices on two different lines, and the distance between the vertices is small. However, I like to have the ability to draw a line between all vertex pairs with a distance less than a certain value. What I like to have is something like a buffer object with the following structure: i1, j1, r1, i2, j2, r2, i3, j3, r3, ... where the i's and j's are indices pointing to vertices and the r's are the distances between those vertices. Thus every vertex pair is stored as a (i, j, r) tuple. Then I like to have a (vertex) shader which only draws the vertex pairs with r < SOME_VALUE as a line. So my question is, what is the best way to achieve this?

  • WPF tree data binding model & repository

    - by Am
    Hi, I have a well defined tree repository. Where I can rename items, move them up, down, etc. Add new and delete. The data is stored in a table as follows: Index Parent Label Left Right 1 0 root 1 14 2 1 food 2 7 3 2 cake 3 4 4 2 pie 5 6 5 1 flowers 8 13 6 5 roses 9 10 7 5 violets 11 12 Representing the following tree: (1) root (14) (2) food (7) (8) flowers (13) (3) cake (4) (5) pie (6) (9) roeses (10) (11) violets (12) or root food cake pie flowers roses violets Now, my problem is how to represent this in a bindable way, so that a TreeView can handle all the possible data changes? Renaming is easy, all I need is to make the label an updatble field. But what if a user moves flowers above food? I can make the relevant data changes, but they cause a complete data change to all other items in the tree. And all the examples I found of bindable hierarchies are good for non static trees.. So my current (and bad) solution is to reload the displayed tree after relocation change. Any direction will be good. Thanks

  • get and set for class in model - MVC 2 asp.net

    - by bergin
    Hi there, I want to improve the program so it has a proper constructor but also works with the models environment of MVC. I currently have: public void recordDocument(int order_id, string filename, string physical_path, string slug, int bytes) { ArchiveDocument doc = new ArchiveDocument(); doc.order_id = order_id; doc.filename = filename; doc.physical_path = physical_path; doc.slug = slug; doc.bytes = bytes; db.ArchiveDocuments.InsertOnSubmit(doc); } This obviously should be a constructor and should change to the leaner: public void recordDocument(ArchiveDocument doc) { db.ArchiveDocuments.InsertOnSubmit(doc); } with a get & set somewhere else - not sure of the syntax - do I create a partial class? so: creating in the somewhere repository - ArchiveDocument doc = new ArchiveDocument(order_id, idTaggedFilename, physical_path, slug, bytes); and then: namespace ordering.Models { public partial class ArchiveDocument { int order_id, string filename, string physical_path, string slug, int bytes; public archiveDocument(int order_id, string filename, string physical_path, string slug, int bytes){ this.order_id = order_id; etc } } How should I alter the code?

  • C++ containers on classes, returning pointers

    - by otneil
    Hello, I'm having some trouble to find the best way to accomplish what I have in mind due to my inexperience. I have a class where I need to a vector of objects. So my first question will be: is there any problem having this: vector< AnyType container* and then on the constructor initialize it with new (and deleting it on the destructor)? Another question is: if this vector is going to store objects, shouldn't it be more like vector< AnyTipe* so they could be dynamically created? In that case how would I return an object from a method and how to avoid memory leaks (trying to use only STL)?

  • Custom object based on database table

    - by Archangel
    Suppose that I have a database query which looks like below - select name, gender, birthday from person where person_id = 1; When this query is executed, some records from the database are returned. I want to make a custom object which will contain the exact attributes as the column names, with the corresponding values. As an example, suppose that the object is X. So it will have three attributes which are X.name, X.gender and X.birthday, with the corresponding values from the records. Is it doable in PHP? If so, then how?

  • Howto: Access a second related model in a nested attribute builder block

    - by Joe Cairns
    I have a basic has_many through relationship: class Foo < ActiveRecord::Base has_many :bars, :dependent => :destroy has_many :wtfs :through => :bars accepts_nested_attributes_for :bars, :wtfs end On my crud forms I have a builder block for the wtf, but I need the label to come from the bar (an attribute called label for instance). What's the proper method to do this? Here's the most simple scaffold: <h1>New foo</h1> <% form_for(@foo) do |f| %> <%= f.error_messages %> <p> <%= f.label :name %><br /> <%= f.text_field :name %> </p> <h2>Bars</h2> <% f.fields_for :wtfs do |builder| %> <%= builder.hidden_field :bar_id %> <p> <%= builder.text_field :wtf_data_i_need_to_set %> </p> <% end %> <p> <%= f.submit 'Create' %> </p> <% end %> <%= link_to 'Back', foos_path %>

  • JavaScript, transform object into array

    - by Šime Vidas
    I've got an object: var obj = { "Mike": 24, "Peter": 23, "Simon": 33, "Tom": 12, "Frank": 31 }; I want to create an array that holds the values of the object. The keys (key names) can be disregarded: [24, 23, 33, 12, 31] The order of the values is NOT important! One solution (obviously) would be do have a function that takes the values and puts them into an array: var arr = valuesToArray(obj); I will accept such a function as the answer. However, I would be more pleased if there would be an API function (ECMAScript, jQuery, browser-specific, ...) that could do this. Is there such a thing?

  • How to pass object in :with field for a link_to_remote call

    - by mathee
    I have an object elem that I'd like to pass to the remove_tag_from_cart method. Here is my attempt: -elem = @tags[1] #{elem.name}#{link_to_remote image_tag('x.png'), :url => {:controller => 'questions', :action => 'remove_tag_from_cart'}, :with => {:tag_to_remove => :elem}} The :with clause isn't working correctly. The image does not even show up. If I take out the :with clause, then the link properly shows up and calls the method correctly, but I need the elem object in order to remove it from the cart. Suggestions?

  • Android -- Object Creation/Memory Allocation vs. Performance

    - by borg17of20
    Hello all, This is probably an easy one. I have about 20 TextViews/ImageViews in my current project that I access like this: ((TextView)multiLayout.findViewById(R.id.GameBoard_Multi_Answer1_Text)).setText(""); //or ((ImageView)multiLayout.findViewById(R.id.GameBoard_Multi_Answer1_Right)).setVisibility(View.INVISIBLE); My question is this, am I better off, from a performance standpoint, just assigning these object variables? Further, am I losing some performance to the constant "search" process that goes on as a part of the findViewById(...) method? (i.e. Does findsViewById(...) use some sort of hashtable/hashmap for look-ups or does it implement an iterative search over the view hierarchy?) At present, my program never uses more than 2.5MB of RAM, so will assigning 20 or so more object variables drastically affect this? I don't think so, but I figured I'd ask. Thanks.

  • Fetching JSON object from Servlet Java

    - by ChrisA
    I want to create an application that will fetch a JSON object from a servlet to deserialize it, and then use its variables to do other things. My servlet has the following code in the doPost: protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { ObjectOutputStream os; os = new ObjectOutputStream(response.getOutputStream()); String s = new String("A String"); Gson gson = new Gson(); String gsonObject= gson.toJson(s); os.writeObject(gsonObject); os.close(); } Now, while the servlet is running, I can access it via a browser, if I post same code in the doGet method, that would download a servlet file, which is not what I want. What should I use in my second application that would connect to the servlet, fetch the object, so that I can manipulate it later? Thanks in advance.

  • Implementing Transparent Persistence

    - by Jules
    Transparent persistence allows you to use regular objects instead of a database. The objects are automatically read from and written to disk. Examples of such systems are Gemstone and Rucksack (for common lisp). Simplified version of what they do: if you access foo.bar and bar is not in memory, it gets loaded from disk. If you do foo.bar = baz then the foo object gets updated on disk. Most systems also have some form of transactions, and they may have support for sharing objects across programs and even across a network. My question is what are the different techniques for implementing these kind of systems and what are the trade offs between these implementation approaches?

  • SSIS web service task producing "object reference" error

    - by gfrizzle
    Our care management system uses a web service to import data. I've successfully executed one of its methods using soapUI, and now I want to replicate this with an SSIS 2008 web service task, but I'm running into a problem. I've created the "HTTP Connection Manager" successfully, and specified the location of the "WSDLFile", but when I go to the Input tab and select the Service from the dropdown (there is only one), I get an "Object reference not set to an instance of an object" error, and and the Method dropdown is empty. Any idea what this is trying to tell me?

  • Writing out sheet to text file using POI event model

    - by Eduardo Dennis
    I am using XLSX2CSV example to parse large sheets from a workbook. Since I only need to output the data for specific sheets I added an if statement in the process method to test for the specific sheets. When the condition is met I continue with the process. public void process() throws IOException, OpenXML4JException, ParserConfigurationException, SAXException { ReadOnlySharedStringsTable strings = new ReadOnlySharedStringsTable(this.xlsxPackage); XSSFReader xssfReader = new XSSFReader(this.xlsxPackage); StylesTable styles = xssfReader.getStylesTable(); XSSFReader.SheetIterator iter = (XSSFReader.SheetIterator) xssfReader.getSheetsData(); while (iter.hasNext()) { InputStream stream = iter.next(); String sheetName = iter.getSheetName(); if (sheetName.equals("SHEET1")||sheetName.equals("SHEET2")||sheetName.equals("SHEET3")||sheetName.equals("SHEET4")||sheetName.equals("SHEET5")){ processSheet(styles, strings, stream); try { System.setOut(new PrintStream( new FileOutputStream("C:\\Users\\edennis.AD\\Desktop\\test\\"+sheetName+".txt"))); } catch (Exception e) { e.printStackTrace(); } stream.close(); } } } But I need to output text file and not sure how to do it. I tried to use the System.set() method to output everything from system.out to text but that's not working I just get blank files.
