• How to add a has_many association on all models

  - by joshsz

  Right now I have an initializer that does this: ActiveRecord::Base.send :has_many, :notes, :as => :notable ActiveRecord::Base.send :accepts_nested_attributes_for, :notes It builds the association just fine, except when I load a view that uses it, the second load gives me: can't dup NilClass from: /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:2184:in `dup' /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:2184:in `scoped_methods' /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:2188:in `current_scoped_methods' /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:2171:in `scoped?' /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:2439:in `send' /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:2439:in `initialize' /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/reflection.rb:162:in `new' /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/reflection.rb:162:in `build_association' /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/associations/association_collection.rb:423:in `build_record' /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/associations/association_collection.rb:102:in `build' (my app)/controllers/manifests_controller.rb:21:in `show' Any ideas? Am I doing this the wrong way? Interestingly if I move the association onto just the model I'm working with at the moment, I don't get this error. I figure I must be building the global association incorrectly.

• Serialization of generic types - GWT

  - by sarav

  I have an interface like this public interface IField<T> extends IsSerializable { public String getKey(); public void setKey(String name); public T getValue(); public void setValue(T role); } And a class like this public class FieldImpl<T> implements IField<T> { private String key; public String getKey() { return key; } public void setKey(String key) { this.key = key; } public T getValue() { return value; } public void setValue(T value) { this.value = value; } private T value; public FieldImpl() { } public FieldImpl(String key, T value) { super(); this.key = key; this.value = value; } } When I try to compile I'm getting [ERROR] In order to produce smaller client-side code, 'Object' is not allowed; please use a more specific type (reached via server.sdk.model.IField) What is the cause for this? Is there any place I can read about GWT's generics support?

• Ultra-grand super acts_as_tree rails query

  - by Bloudermilk

  Right now I'm dealing with an issue regarding an intense acts_as_tree MySQL query via rails. The model I am querying is Foo. A Foo can belong to any one City, State or Country. My goal is to query Foos based on their location. My locations table is set up like so: I have a table in my database called locations I use a combination of acts_as_tree and polymorphic associations to store each individual location as either a City, State or Country. (This means that my table consists of the rows id, name, parent_id, type) Let's say for instance, I want to query Foos in the state "California". Beside Foos that directly belong to "California", I should get all Foos that belong every City in "California" like Foos in "Los Angeles" and "San Francisco". Not only that, but I should get any Foos that belong to the Country that "California" is in, "United States". I've tried a few things with associations to no avail. I feel like I'm missing some super-helpful Rails-fu here. Any advice?

• How to create a reference tables for collection classes using fluent nhibernate

  - by Akk

  How can i create a 3 table schema from the following model classes. public class Product { public int Id {get; set;} public string Name {get; set;} public IList<Photo> Photos {get; set;} } public class Photo { public int Id {get; set;} public string Path {get; set;} } I want to create the following table structure in the database: Product ------- Id Name ProductPhotos ------------- ProductId (FK Products.Id) PhotoId (FK Photos.Id) Photos ------ Id Path How i can express the above Database Schema using Fluent NHibernate? I could only manage the following the Mapping but this does not get me the 3rd Photo ref table. public class ProductMap : ClassMap<Product> { public CityMap() { Id(x => x.Id); Map(x => x.Name); Table("Products"); HasMany(x => x.Photos).Table("ProductPhotos").KeyColumn("ProductId"); } }

• Where should my "filtering" logic reside with Linq-2-SQL and ASP.NET-MVC in View or Controller?

  - by Nate Bross

  I have a main Table, with several "child" tables. TableA and TableAChild1 and TableAChild2. I have a view which shows the information in TableA, and then has two columns of all items in TableAChild1 and TableAChild2 respectivly, they are rendered with Partial views. Both child tables have a bit field for VisibleToAll, and depending on user role, I'd like to either display all related rows, or related rows where VisibleToAll = true. This code, feels like it should be in the controller, but I'm not sure how it would look, because as it stands, the controller (limmited version) looks like this: return View("TableADetailView", repos.GetTableA(id)); Would something like this be even work, and would it be bad what if my DataContext gets submitted, would that delete all the rows that have VisibleToAll == false? var tblA = repos.GetTableA(id); tblA.TableAChild1 = tblA.TableAChild1.Where(tmp => tmp.VisibleToAll == true); tblA.TableAChild2 = tblA.TableAChild2.Where(tmp => tmp.VisibleToAll == true); return View("TableADetailView", tblA); It would also be simple to add that logic to the RendarPartial call from the main view: <% Html.RenderPartial("TableAChild1", Model.TableAChild1.Where(tmp => tmp.VisibleToAll == true); %>

• Obfuscating ids in Rails app

  - by fphilipe

  I'm trying to obfuscate all the ids that leave the server, i.e., ids appearing in URLs and in the HTML output. I've written a simple Base62 lib that has the methods encode and decode. Defining—or better—overwriting the id method of an ActiveRecord to return the encoded version of the id and adjusting the controller to load the resource with the decoded params[:id] gives me the desired result. The ids now are base62 encoded in the urls and the response displays the correct resource. Now I started to notice that subresources defined through has_many relationships aren't loading. e.g. I have a record called User that has_many Posts. Now User.find(1).posts is empty although there are posts with user_id = 1. My explanation is that ActiveRecord must be comparing the user_id of Post with the method id of User—which I've overwritten—instead of comparing with self[:id]. So basically this renders my approach useless. What I would like to have is something like defining obfuscates_id in the model and that the rest would be taken care of, i.e., doing all the encoding/decoding at the appropriate locations and preventing ids to be returned by the server. Is there any gem available or does somebody have a hint how to accomplish this? I bet I'm not the first trying this.

• load data from grid row into (pop up) form for editing

  - by user1495457

  I read in Ext JS in Action ( by J. Garcia) that if we have an instance of Ext.data.Record, we can use the form's loadRecord method to set the form's values. However, he does not give a working example of this (in the example that he uses data is loaded into a form through a file called data.php). I have searched many forums and found the following entry helpful as it gave me an idea on how to solve my problem by using form's loadRecord method: load data from grid to form Now the code for my store and grid is as follows: var userstore = Ext.create('Ext.data.Store', { storeId: 'viewUsersStore', model: 'Configs', autoLoad: true, proxy: { type: 'ajax', url: '/user/getuserviewdata.castle', reader: { type: 'json', root: 'users' }, listeners: { exception: function (proxy, response, operation, eOpts) { Ext.MessageBox.alert("Error", "Session has timed-out. Please re-login and try again."); } } } }); var grid = Ext.create('Ext.grid.Panel', { id: 'viewUsersGrid', title: 'List of all users', store: Ext.data.StoreManager.lookup('viewUsersStore'), columns: [ { header: 'Username', dataIndex: 'username' }, { header: 'Full Name', dataIndex: 'fullName' }, { header: 'Company', dataIndex: 'companyName' }, { header: 'Latest Time Login', dataIndex: 'lastLogin' }, { header: 'Current Status', dataIndex: 'status' }, { header: 'Edit', menuDisabled: true, sortable: false, xtype: 'actioncolumn', width: 50, items: [{ icon: '../../../Content/ext/img/icons/fam/user_edit.png', tooltip: 'Edit user', handler: function (grid, rowIndex, colIndex) { var rec = userstore.getAt(rowIndex); alert("Edit " + rec.get('username')+ "?"); EditUser(rec.get('id')); } }] }, ] }); function EditUser(id) { //I think I need to have this code here - I don't think it's complete/correct though var formpanel = Ext.getCmp('CreateUserForm'); formpanel.getForm().loadRecord(rec); } 'CreateUserForm' is the ID of a form that already exists and which should appear when user clicks on Edit icon. That pop-up form should then automatically be populated with the correct data from the grid row. However my code is not working. I get an error at the line 'formpanel.getForm().loadRecord(rec)' - it says 'Microsoft JScript runtime error: 'undefined' is null or not an object'. Any tips on how to solve this?

• Preloading data without messing up association when data is loaded the 2nd time.

  - by denniss

  This is how my model looks like User belongs_to :computer Computer has_many :user Users are created when people register for an account on the web site but computers are pre-loaded data that I create in seeds.rb/some .rake file. All is fine and good when the app is first launched and people start registering and get associated with the right computer_id. However, suppose I want to add another computer to the list Computer.destroy_all Computer.create({:name => "Akane"}) Computer.create({:name => "Yoda"}) Computer.create({:name => "Mojito"}) #newly added running the rakefile the second time around will mess up the associations because computer_id in the User table refer to the old id in Computer table. Since I have run the script above, the id keeps incrementing without any regard to the association that user has to it. Question: Is there a better way for me to pre-load data without screwing up my association? I want to be able to add new Computer without having to destroy the user's table. Destroying the computer table is fine with me and rebuilding it again but the old association that the existing users have must stay intact.

• how to fetch more than 1000 entities NON keybased?

  - by user291071

  If I should be approaching this problem through a different method, please suggest so. I am creating an item based collaborative filter. I populate the db with the LinkRating2 class and for each link there are more than a 1000 users that I need to call and collect their ratings to perform calculations which I then use to create another table. So I need to call more than 1000 entities for a given link. For instance lets say there are over a 1000 users rated 'link1' there will be over a 1000 instances of this class for the given link property that I need to call. How would I complete this example? class LinkRating2(db.Model): user = db.StringProperty() link = db.StringProperty() rating2 = db.FloatProperty() query =LinkRating2.all() link1 = 'link string name' a = query.filter('link = ', link1) aa = a.fetch(1000)##how would i get more than 1000 for a given link1 as shown? ##keybased over 1000 in other post example i need method for a subset though not key class MyModel(db.Expando): @classmethod def count_all(cls): """ Count *all* of the rows (without maxing out at 1000) """ count = 0 query = cls.all().order('__key__') while count % 1000 == 0: current_count = query.count() if current_count == 0: break count += current_count if current_count == 1000: last_key = query.fetch(1, 999)[0].key() query = query.filter('__key__ > ', last_key) return count

• Are there any less costly alternatives to Amazon's Relational Database Services (RDS)?

  - by swapnonil

  Hi All, I have the following requirement. I have with me a database containing the contact and address details of at least 2000 members of my school alumni organization. We want to store all that information in a relation model so that This data can be created and edited on demand. This data is always backed up and should be simple to restore in case the master copy becomes unusable. All sensitive personal information residing in this database is guaranteed to be available only to authorized users. This database won't be online in the first 6 months. It will become online only after a website is built on top of it. I am not a DBA and I don't want to spend time doing things like backups. I thought Amazon's RDS with it's automatic backup facility was the perfect solution for our needs. The only problem is that being a voluntary organization we cannot spare the monthly $100 to $150 fees this service demands. So my question is, are there any less costlier alternatives to Amazon's RDS?

• Ruby on Rails - pass variable to nested form

  - by Krule

  I am trying to build a multilingual site using Rails, but I can't figure out how to pass variable to nested form. Right now I am creating nested form like this. @languages.each do @article.article_locale.build(:language_id => language.id) end But i would like to pass value of language to it so i can distinguish fields. Something like this. @languages.each do |language| @language = language @article.article_locale.build(:language_id => language.id) end However, I always end up with language of the last loop iteration. Any way to pass this variable? -- edit -- In the end, since I've got no answer I have solved this problem so it, at least, works as it should. Following code is my partial solution. In model: def self.languages Language.all end def self.language_name language = [] self.languages.each_with_index do |lang, i| language[i] = lang.longname end return language end In Controller: def new @article = Article.new Article.languages.each do |language| @article.article_locale.build(:language_id => language.id) end end In HAML View: -count = 0 -f.fields_for :article_locale do |al| %h3= Article.language_name[count] -count+=1 -field_set_tag do %p =al.label :name, t(:name) =al.text_field :name %p =al.label :description, t(:description) =al.text_area :description =al.hidden_field :language_id It's not the most elegant solution I suppose, but it works. I would really love if I could get rid of counter in view for instance.

• NotApplicable marker with display pattern

  - by Jeff Barger

  Ok, so I'm pretty new to Cocoa, especially Bindings, but here's what I'm trying to do. I've got a Core Data model consisting of two entities: Category and Item. Category has a to-many relationship to Item called children, and Item has a relationship to Category called parent. Item has two attributes that Category does not have: quantity and desiredQuantity. What I'd like to do is display the tree in an NSOutlineView with two columns. One column is bound to the name of either the Category or the Item. I want to the second column to display something along the lines of 2 of 5 for the Item rows and nothing at all for the Category rows. When I use a display pattern, the Category rows end up showing of I noticed that if I don't use a display pattern for the second column, and instead just bind its Value to either the quantity or the desiredQuantity, the Category rows show nothing; its only if I try to use the display pattern. How can I make it display nothing for the Category rows and still use the display pattern? Or can I? Edit: I guess I didn't explain what the NotApplicable marker has to do with anything - Category does have properties for quantity and desiredQuantity, but they just return NSNotApplicableMarker.

• How to change image on locale base in magento?

  - by Nil

  I want to change search image in magento. On search in magento the image name is btn_search.gif. Right now it take image from skin/frontend/default/default/images. And the file is /app/design/frontend/default/default/template/catalogsearch/form.mini.phtml where mention this tag as <input id="search-button" type="image" src="<?php echo $this->getSkinUrl('images/btn_search.gif') ?>" alt="<?php echo $this->__('Search') ?>" /> I check the code and i found that we can pass locale as _type in this as <input id="search-button" type="image" src="<?php echo $this->getSkinUrl('images/btn_search.gif', array('_type'=>'local')) ?>" alt="<?php echo $this->__('Search') ?>" /> But when i check the code this will just check in locale directory that this file exist in that locale or not. If this exist then it will take skin image. I want to use that locale image instead of that skin image. So when i click on french store i get the image which is i set in /app/design/frontend/default/default/locale/fr_FR/images/btn_search.gif I check the code for getSkinUrl in /app/code/core/Mage/Core/Model/Design/Package.php. And i found that he check locale for file but it return skin url. Is there any method which return locale url ?

• Connecting a django application to a drupal database?

  - by Hans

  I have a 3 - 4000 nodes in a drupal 6 installation on mysql and want to access these data through my django application. I have used manage.py inspectdb to get a skeleton of a model structure. I guess that there are good/historical reasons for drupal's database schemes, but find that there are some hard to understand structure and that there are some challenges in applying django models on the database. Some experiences this far are: node and node revision are intertwined and I solved this by using a OneToOneField (don't need the versions). This meens that the node's body gets accessible through node.vid.body, but it works. Foreign keys need to define the proper db_column to sort out the primary keys. Terms need to use an intermediary table with ManyToManyField.through. Drupal stores both the original and the thumbnailed/resized versions of any image as files in the files table. Does anyone have experiences in accessing drupal data in django? Are there better solution to for example the node <- node revision relationship? Drupal stores time/dates as unix-style timestamps in integerfields. Any recommendations? How about time zones?

• formatting mysql data for ouptut into a table

  - by bsandrabr

  Following on from a question earlier today this answer was given to read the data into an array and separate it to print vehicle type and then some data for each vehicle. <?php $sql = "SELECT * FROM apparatus ORDER BY vehicleType"; $getSQL = mysql_query($sql); // transform the result set: $data = array(); while ($row = mysql_fetch_assoc($getSQL)) { $data[$row['vehicleType']][] = $row; } ?> <?php foreach ($data as $type => $rows): ?> <h2><?php echo $type?></h2> <ul> <?php foreach ($rows as $vehicleData):?> <li><?php echo $vehicleData['name'];?></li> <?php endforeach ?> </ul> <?php endforeach ?> This is almost perfect for what I want to do but I need to print out two columns from the database ie ford and mondeo before going into the second foreach loop. I've tried print $rows['model'] and all the other combinations I can think of but that doesn't work. Any help much appreciated

• Configure nHibernate for multiple-project solution

  Hello, Im doing a project with C# winforms. This project is composed by: Client project: Windows Forms where user will do CRUD operations on the models; Server project; Common Project: This project will hold the models (in the image only have the model Item); ListSingleton: Remote Object that will do the operations on the models; I already have all the communication working, but now I need to work on the persistence of the data in a mysql database. I was trying to use nHibernate but I’m having some troubles. My main problem is how to organize my hibernate configuration. In which project do I keep the mapping? Common project? In which project do I keep the hibernate configuration file (App.config)? ListSingleton project? In which project do I do this: Configuration cfg = new Configuration(); cfg.AddXmlFile("Item.hbm.xml"); ISessionFactory factory = cfg.BuildSessionFactory(); ISession session = factory.OpenSession(); ITransaction transaction = session.BeginTransaction(); Item newItem = new Item("BLAA"); // Tell NHibernate that this object should be saved session.Save(newItem); // commit all of the changes to the DB and close the ISession transaction.Commit(); session.Close(); In the ListSingleton project?

• iPhone SDK Programming - Working with a variable across 2 views

  - by SD

  I have what I hope is a fairly simple question about using the value from a variable across 2 views. I’m new to the iPhone SDK platform and the Model/View/Controller methodology. I’ve got background in VB.Net, some Php, but mostly SQL, so this is new ground for me. I’m building an app that has 3 views. For simplicity’s sake, I’ll call them View1, View2, View3. On View1 I have an NSString variable that I’ve declared in View1.h, and synthesized in View1.m. I’ll call it String1. View1.m uses a UITextField to ask the user for their name and then sets the value of String1 to that name (i.e. "Bill"). I would now like to use the value of String1 in View2. I'm not doing anything other than displaying the value ("Bill"), in a UILabel object in View2. Can someone tell me what the easiest way to accomplish that is? Many thanks in advance….

• How to check if an entityset is populated

  - by TheQ

  How can i check if an entityset of a linq-object is populated or not? Example code below. My model have two methods, one joins data, and the other does not: public static Member GetMemberWithSettings(Guid memberId) { using (DataContext db = new DataContext()) { DataLoadOptions dataLoadOptions = new DataLoadOptions(); dataLoadOptions.LoadWith<Member>(x => x.Settings); db.LoadOptions = dataLoadOptions; var query = from x in db.Members where x.MemberId == memberId select x; return query.FirstOrDefault(); } } public static Member GetMember(Guid memberId) { using (DataContext db = new DataContext()) { var query = from x in db.Members where x.MemberId == memberId select x; return query.FirstOrDefault(); } } Then my control have the following code: Member member1 = Member.GetMemberWithSettings(memberId); Member member2 = Member.GetMember(memberId); Debug.WriteLine(member1.Settings.Count); Debug.WriteLine(member2.Settings.Count); The last line will generate a "Cannot access a disposed object" exception. I know that i can get rid of that exception just by not disposing the datacontext, but then the last line will generate a new query to the database, and i don't want that. What i would like is something like: Debug.WriteLine((member1.Settings.IsPopulated()) ? member1.Settings.Count : -1); Debug.WriteLine((member2.Settings.IsPopulated()) ? member2.Settings.Count : -1); Is it possible?

  Hi all im having provlem with this jquery function, the protion of the function that renames the id, class and name of the dropdown only works for the first dropdown, susequest ones do not work , any ideas, i suspect it may have something to do with naming convention as in cat.parent_id but it is required for asp.net mvc model binding. $(document).ready(function () { $("table select").live("change", function () { var id = $(this).attr('id'); if ($(this).attr('classname') != "selected") { var rowIndex = $(this).closest('tr').prevAll().length; $.getJSON("/Category/GetSubCategories/" + $(this).val(), function (data) { if (data.length > 0) { //problematic portion $("#" + id).attr('classname', 'selected'); $("#" + id).attr('name', 'sel' + rowIndex); $("#" + id).attr('id', 'sel' + rowIndex); var position = ($('table').get(0)); var tr = position.insertRow(rowIndex + 1); var td1 = tr.insertCell(-1); var td2 = tr.insertCell(-1); td1.appendChild(document.createTextNode('SubCategory')); var sel = document.createElement("select"); sel.name = 'parent_id'; sel.id = 'parent_id'; sel.setAttribute('class', 'unselected'); td2.appendChild(sel); $('#parent_id').append($("<option></option>").attr("value", "-1").text("-please select item-")); $.each(data, function (GetSubCatergories, Category) { $('#parent_id').append($("<option></option>"). attr("value", Category.category_id). text(Category.name)); }); sel.name = 'cat.parent_id'; sel.id = 'cat.parent_id'; } }); } }); });

• CakePHP – 2 controllers, 1 form

  - by user1327

  I need to create a review form. I have 2 models and 2 controllers – Products and Reviews with 'Products' hasMany 'Reviews' relationship, the review form will be displayed on the current product page (Products controller, 'view' action), and this form will be use another controller (Reviews). Also I need validation with validation errors being displayed for this form. In my Products controller view.ctp I have: // product page stuff... echo $this->Form->create($model = 'Review', array('url' => '/reviews/add')); echo $this->Form->input('name', array('label' => 'Your name:')); echo $this->Form->input('email', array('label' => 'Your e-mail:')); echo $this->Form->input('message', array('rows' => '6', 'label' => 'Your message:')); echo $this->Form->end('Send'); echo $this->Session->flash(); ReviewsController - add: public function add() { if ($this->request->is('post')) { $this->Review->save($this->request->data); $this->redirect(array('controller' => 'products', 'action' => 'view', $this->request->data['Review']['product_id'], '#' => 'reviews')); } } Somehow this horrible code works.. in part. Review saves, but I don't get validation errors, and I can't add 'if ($this->Review->save($this->request->data);) { //... } because it will break this action (missed view error). My question is how to properly deal with this situation to achieve functionality that I need? Should I use elements with request action or I should move adding reviews to the ProductsController?

• looking for advise on importing excel into mysql with php

  - by Ole Media

  Alright, see if I can pick your brains from you all. I'm currently working on a project where all the information comes from different clients, the only thing in common is that the received data is done with excel. The excel spread sheet that they present is just a bunch of references and codes, and the problem than I'm facing is that I need the references and codes to be entered in certain format in order for the website to work. The perfect situation will be to go to each client and teach how I would need the data, but I can't do that because of the large number of clients, and more importantly I will be interrupting their work flow. Each client has its own codes and reference model and they are not willing to change their process The good news is that there is a standard pattern for the codes, but I'm talking close to 200 thousand codes with a bunch of combination. They way that we are currently solving the problem is that we have a person who checks each excel sheet received, runs a few macros, and manually fixes those codes in which the macro was not able to fix. The person that is doing this, is already burn out and frustrated and I would like to automatize this process with php. Suggestions?
