  • Mongoose Not Creating Indexes

    - by wintzer
    I have been trying all afternoon to get my node.js application to create MongoDB indexes properly. I am using the Mongoose ODM and in my schema definition below I have the username field set to a unique index. The collection and document all get created properly, it's just the indexes that aren't working. All the documentation says that the ensureIndex command should be run at startup to create any indexes, but none are being made. I'm using MongoLab for hosting if that matters. I have also repeatedly dropped the collection. Please tell me what I'm doing wrong. var schemaUser = new mongoose.Schema({ username: {type: String, index: { unique: true }, required: true}, hash: String, created: {type: Date, default: Date.now} }, { collection:'Users' }); var User = mongoose.model('Users', schemaUser); var newUser = new Users({username:'wintzer'}) newUser.save(function(err) { if (err) console.log(err); });

    - by niaher
    Is it possible to pass array of models from view to controller? How? Suppose my model is public class Car { public string Name { get; set; } public int Price { get; set; } } And I have a <form> where user can dynamically add new cars. When he submits, I want to catch it in the action method public ActionResult CreateCars(Car[] cars) Is it possible?

  • Data-binding taking to long to update

    - by Justin
    In my application I have this code in my view model: hiddenTextContainer.PreHideVerticalOffset = VerticalOffset; hiddenTextContainer.HiddenText = Text.Remove(SelectionStart, SelectionLength); hiddenTextContainer.HasHiddenText = true; hiddenTextContainer.NonHiddenTextStart = SelectionStart; Text = Text.Substring(SelectionStart, SelectionLength); SelectionStart = Text.Length; hiddenTextContainer.ImmediatePostHideVerticalOffset = VerticalOffset; This code is used to hide selected text in a textbox. Text is a string property data bound to the text property of a textbox and VerticalOffset is a double property data bound to the VerticalOffset property of that same textbox. I need to save the VerticalOffset before and after the hiding of selected text takes place, but with my code below both hiddenTextContainer.PreHideVerticalOffset and hiddenTextContainer.ImmediatePostHideVerticalOffset are always set to the same value no matter what. I have figured out that this is because the text of the textbox has not been updated by the time the code reaches: hiddenTextContainer.ImmediatePostHideVerticalOffset = VerticalOffset; Is there any way I can fix this?

  • Disable Foreign Key Exposure in Entity Framework?

    - by davemackey
    When I originally created a Dynamic Data project I told it to expose the foreign keys, but now I can't make mappings between two entities b/c of the foreign keys. When I click on mapping details while focused on my association I receive the message: Mappings are not allow for an association over exposed foreign keys. So I'd like to disable the exposure of the foreign keys but am unsure how to do this without creating a new Entity Model from scratch. I'm not far along - so that wouldn't be hard, but I imagine there must be a programmatic switch for this?

  • Does TCP actually define 'TCP server' and 'TCP clients'? [closed]

    - by mjn
    In the Wikipedia article, TCP communication is explained using the terms 'client' and 'server'. It also uses the word 'peers'. But TCP actually does not define "TCP clients" and "TCP servers" - In the RFC 675 document (SPECIFICATION OF INTERNET TRANSMISSION CONTROL PROGRAM), the word "client" never appears. The RFC explains that TCP is used to connect processes over ports (sockets), and that 'A pair of sockets form a CONNECTION which can be used to carry data in either direction [i.e. full duplex]. Calling the originating party the "client" seems to be common practice. But this client/server communication model is not always applicable to TCP communication. For example take peer-to-peer networks. Calling all processes which open a socket (and wait for incoming connections from peers) "TCP servers", sounds wrong to me. I would not call my uncle's telephone device a "Telephony server" if I dial his phone number and he picks up.

  • Multiple databases support in Symfony

    - by Ngu Soon Hui
    I am using Propel as my DAL for my Symfony project. I can't seem to get my application to work across two or more databases. Here's my schema.yml: db1: lkp_User: pk_User: { type: integer, required: true, primaryKey: true, autoIncrement: true } UserName: { type: varchar(45), required: true } Password: longvarchar _uniques: Unique: [ UserName ] db2: tesco: Id: { type: integer, required: true, primaryKey: true, autoIncrement: true } Name: { type: varchar(45), required: true } Description: longvarchar And here's the databases.yml: dev: db1: param: classname: DebugPDO test: db1: param: classname: DebugPDO all: db1: class: sfPropelDatabase param: classname: PropelPDO dsn: 'mysql:dbname=bpodb;host=localhost' #where the db is located username: root password: #pass encoding: utf8 persistent: true pooling: true db2: class: sfPropelDatabase param: classname: PropelPDO dsn: 'mysql:dbname=mystore2;host=localhost' #where the db is located username: root password: #pass encoding: utf8 persistent: true pooling: true When I call php symfony propel-build-model, only db1 is generated, db2 is not. Any idea how to fix this problem?

  • ORM Against a Service-Wrapped Data Source

    - by blaster
    We are tasked with migrating an existing set of entities (currently POCOs persisted with NHibernate against an MSSQL database) to now persist to some kind of web service (yet to be built, either RESTful or SOAP-based, and that we control). I like how NHibernate encapsulates the persistence concerns and lets us maintain a logic-rich, persistence-agnostic domain model. Is there any way to make NHibernate talk to a web service at the back end instead of a SQL database directly? In other words, can "service instead of SQL database" be treated as a persistence implementation detail and allow us to continue to use NHibernate? Am I asking the right question? :)

  • Using xval with fields containing periods

    - by JP
    Hello, I have been using xVal with success for a while but this evening ran into an issue where a field containing a period would not be validated (client or server-side). I am using ASP.NET MVC2 and need to use the period syntax in cases where I am model binding to a list. In the below example I am using a textbox for the sake of simplicity: xVal.AttachValidator(null, { "Fields": [{ "FieldName": "entry[622592].Value", "FieldRules": [{ "RuleName": "Required", "RuleParameters": {}}]}] }, {}) <input type="text" class="text" name="entry[622592].Value"/> If I replace both instances of "entry[622592].Value" to something trivial like "test" then the validation works successfully, but if i leave it this way the validation never appears to fire... Has anyone run into this issue? Thanks in advance!

  • Visualizing branch topology in git

    - by Benjol
    I'm playing with git in isolation on my own machine, and even like that I find it difficult to maintain a mental model of all my branches and commits. I know I can do a git log to see the commit history from where I am, but is there a way to see the entire branch topography, something like these ascii maps that seem to be used everywhere for explaining branches? .-A---M---N---O---P / / / / / I B C D E \ / / / / `-------------' It just feels like someone coming along and trying to pick up my repository would have difficulty working out exactly what was going on. I guess I'm influenced by AccuRev's stream browser...

  • Non-auto-increment rails/postgresql column

    - by Redian
    I'm trying to have a model/table with duplicate information in it. The reason for this is so that the same data can be written to the table under different users and found for each user. However, I want a quick easy way to identify which information is a duplicate of other information. I think the best way to do this would be to have an item_id of sorts that increments with each "set" of entries to the table. Is there a way to do this without including another table that stores the information without attributing it to users?

  • How Many HABTM relationships in cakephp is too many?

    - by user559540
    Hi all, I'm struggling with deciding how many HABTM relationships I really need in my cakephp app. I guess I don't quite get what "has" truly means. I don't want to have more HABTM tables than necessary. Here's what I have in my database: Users Properties Leases Payments Repairs user HABTM properties, user HABTM leases, user HABTM users, user HABTM repairs, property hasMany repairs, property hasMany leases, lease hasMany repairs. Also, I have two aliases for my users model (manager and tenant). This is one of the reasons I ended up with so many HABTM relationships, but I'm not sure it's necessary. Do I have too many user HABTM relationships? Would it be better to just have cake recurse through my models? Thanks!

  • How to use separat block caches for secure and unsecure shop access in Magento?

    - by Uwe Mesecke
    I use the Magento block cache for the top navigation block. The problem is the block has to generate some urls for files in the skin directory that cannot be put into css files as the file names depend on category model data. Now when I open magento using a secure connection (https://) the navigation block is fetched from the cache and is sent to the browser but with the http:// urls resulting in a warning in most browsers about unsecure elements on the page. I'd like the have separat caches for secure and unsecure connections. The navigation block extends the class Mage_Catalog_Block_Navigation and therefore has the following cache configuration: $this->addData(array( 'cache_lifetime' => false, 'cache_tags' => array(Mage_Catalog_Model_Category::CACHE_TAG, Mage_Core_Model_Store_Group::CACHE_TAG), ));

  • Validating primitive types in ASP.NET MVC

    - by Alex
    I've implemented the following classes to validate data public abstract class Validated { public bool IsValid { get { return (GetRuleViolations().Count() == 0); } } public abstract IEnumerable<RuleViolation> GetRuleViolations(); } public partial class User: Validated { public override IEnumerable<RuleViolation> GetRuleViolations() { if (this.Age < 1) yield return new RuleViolation("Age can't be less than 1"); } } It works great! When the form is submitted I just do if (user.IsValid == false) blah... But I still need to validate that the Age is an integer int a = 0; if (!int.TryParse(age, out a)) { error = "Not integer"; // ... } How can I move this to my model?

  • Specify fields in a recursive find with cakephp

    - by Razor Storm
    Suppose I have a table Recipe that hasmany ingredients. I do a recursive find to grab recipes with their associated ingredients: $this->Recipe->find('all', array('fields' => array('id','title','description'))); Here I can use the 'fields' attribute to specify that I only want it to return id, title, and description. However, despite this, cakephp still returns ALL columns from the ingredients table. How do I tell cakephp that I only want ingredient table's id and name fields? btw ingredient model is "Ingredient" and the table is ingredients, and the aggregation table is recipes_ingredients.

  • How can I remove a duplicate object from a MongoDB array?

    - by andrewrk
    My data looks like this: foo_list: [ { id: '98aa4987-d812-4aba-ac20-92d1079f87b2', name: 'Foo 1', slug: 'foo-1' }, { id: '98aa4987-d812-4aba-ac20-92d1079f87b2', name: 'Foo 1', slug: 'foo-1' } { id: '157569ec-abab-4bfb-b732-55e9c8f4a57d', name: 'Foo 3', slug: 'foo-3' } ] Where foo_list is a field in a model called Bar. Notice that the first and second objects in the array are complete duplicates. Aside from the obvious solution of switching to PostgresSQL, what MongoDB query can I run to remove duplicate entries from foo_list? Similar answers that do not quite cut it: http://stackoverflow.com/a/16907596/432 http://stackoverflow.com/a/18804460/432 These questions answer the question if the array had bare strings in it. However in my situation the array is filled with objects. I hope it is clear that I am not interested in a query; I want the duplicates to be gone from the database forever.

  • LINQ query for tag system: Matching any of several tags?

    - by David Veeneman
    I am just getting started with LINQ. I am creating an Entity Framework app that uses the canonical Post and Tag model. A Post contains an ID, Text, and Tags, and a Tag contains an ID, a Name, and Posts. A previous thread on StackOverflow showed me how to query for a Post that matches all Tag objects (A and B and C) in a search list. But how would I query for a Post that matches any Tag (A or B or C) in the list? Thanks for your help.

  • Error 1005 when adding a foreign key constraint on mysql table

    - by luc
    Hello, I have a problem when upgrading a django and mysql app with south. I've tried to make a sql-based upgrade with the code generated by the django sqlall command and I have a similar problem. Here is the sql code: CREATE TABLE `programmations_basissupport` ( `id` integer AUTO_INCREMENT NOT NULL PRIMARY KEY, `value` numeric(6, 0) NOT NULL ) ALTER TABLE `programmations_concert` ADD `basis_support_id` integer AFTER program_status_id; ALTER TABLE `programmations_concert` ADD CONSTRAINT `basis_support_id_refs_id_1e4ed8d7` FOREIGN KEY (`basis_support_id`) REFERENCES `programmations_basissupport` (`id`); An error is raised when adding the FK constraint: ERROR 1005 (HY000): Can't create table 'apidev_mnl.#sql-106e_632b00a' (errno: 150) Does anybody have an idea? Update: DEFAULT values where missing but even if I add the default='' in the django model, the creation of foreign keys fails. Thanks for your help

  • Creating attribute sets and attributes programatically magento

    - by digital_paki
    I am using the code listed on the following link =: http://www.magentocommerce.com/wiki/5_-_modules_and_development/catalog/programmatically_adding_attributes_and_attribute_sets Everything works until the point: // Just add a default group. else { $this->logInfo("Creating default group [{$this->groupName}] for set."); $modelGroup = Mage::getModel('eav/entity_attribute_group'); $modelGroup->setAttributeGroupName($this->groupName); $modelGroup->setAttributeSetId($id); // This is optional, and just a sorting index in the case of // multiple groups. // $modelGroup->setSortOrder(1); $model->setGroups(array($modelGroup)); } I am unsure where the object reference would need to be set from - I am attempting to have this as a separate file that can be automated - I am running this file by doing a require_once 'app/Mage.php'; Mage::app(); Any help in this would be greatly appreciated Thanks

  • Searching and comparing ActiveRecord attributes to find largest value

    - by NS
    I have a model that would look something like: my_diet = Diet.new my_diet.food_type_1 = "beef" my_diet.food_type_1_percentage = 40 my_diet.food_type_2 = "carrots" my_diet.food_type_2_percentage = 50 my_diet.food_type_3 = "beans" my_diet.food_type_3_percentage = 5 my_diet.food_type_4 = "chicken" my_diet.food_type_4_percentage = 5 I need to find which food_type has the highest percentage. So far I've tried creating a hash out of the attibutes and percentages then sorting the hash (see below) but it feels like there must be a cleaner way to do it. food_type_percentages = { :food_type_1 => my_diet.foo_type_percentage_1_percentage.nil? ? 0 : my_dient.food_type_1_percentage, :food_type_2 => my_diet.foo_type_percentage_2_percentage.nil? ? 0 : my_dient.food_type_2_percentage, :food_type_3 => my_diet.foo_type_percentage_3_percentage.nil? ? 0 : my_dient.food_type_3_percentage, :food_type_4 => my_diet.foo_type_percentage_4_percentage.nil? ? 0 : my_dient.food_type_4_percentage } food_type_percentages.sort {|a,b| a[1]<=>b[1]}.last Any ideas? Thanks!

  • Symfony form's i18n and add_empty

    - by David
    I have this widget: $this->setWidget('slug', new sfWidgetFormDoctrineChoice(array('model' => 'MyTable', 'method' => 'myMethod', 'key_method' => 'myMethod', 'add_empty' => 'Select option'))); Ok, what should I do to translate the "Select option"? I can't use the __() helper inside the form, and adding that string into my XLIFF file doesn't translate it automatically. If it can't be done, what workaround should I implement? I can't find any way, and neither can't find any tip in the official documentation. Thanks!

  • What can't the NDK be used for?

    - by Android Eve
    From the official NDK site: The Android NDK... provides headers and libraries that allow you to build activities, handle user input, use hardware sensors, access application resources, and more, when programming in C or C++. If you write native code, your applications are still packaged into an .apk file and they still run inside of a virtual machine on the device. The fundamental Android application model does not change. Yet, it is always described as a companion tool to the Android SDK and as a toolset that allows to "implement parts of your applications using native-code languages such as C and C++". My understanding from this is that, unlike the Java based SDK, the NDK is not designed to implement certain parts of an Android application. Is this correct? If so, what parts doesn't the NDK allow implementing?

  • Wpf button click when application window is not active

    - by byte
    I have a WPF application window with a button (ButtonA) which has a command binding to a View Model property. When another application is launched the focus is lost and application window is deactivated. Clicking ButtonA now doesn’t execute the command but instead only activates the window and sets the focus to the button. 2nd click is required to fire the command. The desired functionality is on click of ButtonA while the application window is not active, the application window activates and command associated with ButtonA is executed. I have also tried removing the command and adding a click handler for test purpose but this displays same behaviour. I appreciate any help with this issue.
