  • find(:all) and then add data from another table to the object

    - by Koning Baard XIV
    I have two tables: create_table "friendships", :force => true do |t| t.integer "user1_id" t.integer "user2_id" t.boolean "hasaccepted" t.datetime "created_at" t.datetime "updated_at" end and create_table "users", :force => true do |t| t.string "email" t.string "password" t.string "phone" t.boolean "gender" t.datetime "created_at" t.datetime "updated_at" t.string "firstname" t.string "lastname" t.date "birthday" end I need to show the user a list of Friendrequests, so I use this method in my controller: def getfriendrequests respond_to do |format| case params[:id] when "to_me" @friendrequests = Friendship.find(:all, :conditions => { :user2_id => session[:user], :hasaccepted => false }) when "from_me" @friendrequests = Friendship.find(:all, :conditions => { :user1_id => session[:user], :hasaccepted => false }) end format.xml { render :xml => @friendrequests } format.json { render :json => @friendrequests } end end I do nearly everything using AJAX, so to fetch the First and Last name of the user with UID user2_id (the to_me param comes later, don't worry right now), I need a for loop which make multiple AJAX calls. This sucks and costs much bandwidth. So I'd rather like that getfriendrequests also returns the First and Last name of the corresponding users, so, e.g. the JSON response would not be: [ { "friendship": { "created_at": "2010-02-19T13:51:31Z", "user1_id": 2, "updated_at": "2010-02-19T13:51:31Z", "hasaccepted": false, "id": 11, "user2_id": 3 } }, { "friendship": { "created_at": "2010-02-19T16:31:23Z", "user1_id": 2, "updated_at": "2010-02-19T16:31:23Z", "hasaccepted": false, "id": 12, "user2_id": 4 } } ] but rather: [ { "friendship": { "created_at": "2010-02-19T13:51:31Z", "user1_id": 2, "updated_at": "2010-02-19T13:51:31Z", "hasaccepted": false, "id": 11, "user2_id": 3, "firstname": "Jon", "lastname": "Skeet" } }, { "friendship": { "created_at": "2010-02-19T16:31:23Z", "user1_id": 2, "updated_at": "2010-02-19T16:31:23Z", "hasaccepted": false, "id": 12, "user2_id": 4, "firstname": "Mark", "lastname": "Gravell" } } ] I thought of a for loop in the getfriendrequests method, but I don't know how to implement this, and maybe there is an easier way. It must also work for XML. Can anyone help me? Thanks

  • How can I save an entire list of items true or false?

    - by JZ
    I'm following Ryan Bates, Railscast episode 52 and I've translated relevant parts of the code to work with Rails 3.0.0.beta2. In Ryan's case, he simply marks items incomplete and saves a timestamp. If an Item contains a timestamp the model returns the item in the completed list. I'm attempting to save ALL values true or false, depending on whether the check_box_tag is selected or not (using boolean). I am able to save ONLY selected items, true or false. How can I save an entire list of items true or false, depending on whether the checkbox is selected? The following is my attempt: controller logic: def yardsign Add.update_all(["yardsign=?", true], :id => params[:yard_ids]) redirect_to adds_path end html.erb: <%= form_tag yardsign_adds_path, :method => :put do %> <% @adds.each do |add| %> <td><%= check_box_tag "yard_ids[]", add.id %></td> <% end %> <% end %> routes.rb resources :adds do collection do put :yardsign end end Terminal Started POST "/adds/yardsign" for 127.0.0.1 at 2010-04-15 19:22:49 Processing by AddsController#yardsign as HTML Parameters: {"commit"=>"Update", "yardsigntakers"=>["1", "2"], "authenticity_token"=>"3arhsxg/Ky+0W7RNM2T3QditMTJmOnLR5CqmMYWN4Qw="} User Load (0.3ms) SELECT "users".* FROM "users" WHERE ("users"."id" = 1) LIMIT 1 SQL (1.8ms) UPDATE "adds" SET yardsign='t' WHERE ("adds"."id" IN (1, 2)) Redirected to http://localhost:3000/adds

  • What's the compelling reason to upgrade to Visual Studio 2010 from VS2008?

    - by Cheeso
    Are there new features in Visual Studio 2010 that are must-haves? If so, which ones? For me, the big draws for VS2008 as compared to VS2005 were LINQ, .NET Framework multitargeting, WCF (REST + Syndication), and general devenv.exe reliability. Granted, some of these features are framework things, and not tool things. For the purposes of this discussion, I'm willing to combine them into one bucket. What is the list of must-have features for VS2010 versus VS2008? Are there any? I am particularly interested in C#. Update: I know how to google, so I can get the official list from Microsoft. I guess what I really wanted was, the assessment from people using it, as to which things are really notable. Microsoft went on for 3 pages about 2008/3.5 features, and many people sort of boiled it down to LINQ, and a few other things. What is that short list for VS2010? Summary so far, what people think is cool or compelling: Visual Studio engine multi-monitor support new extensibility model based on WPF, prettier and more usable new TFS stuff, incl automated test tools parallel debugging .NET Framework parallel extensions for .NET C# 4.0 generic variance optional and named params easier interop with non-managed environments, like COM or Javascript VB 10.0 collection and array literals / initializers automatic properties anonymous methods / statement lambdas I read up on these at Zander's blog. He described these and other features. Nobody on this list said anything about: Visual Studio engine F# support Javascript code-completion JQuery is now included UML better Sharepoint capabilities C++ moves to msbuild project files

  • 406 Not Acceptable error when using Jquery $.post in Firefox but not in Safari or Chrome

    - by jlfenaux
    I'm using Jquery (1.3.2) $.post command to trigger an ajax call to a rails server. The code works great on Safari and on Google Chrome (mac), but when I tried it on Firefox (3.5.7), I got a weird '406 Not Acceptable' error. When I look at the headers, it Firefox indicated that it accepted only ' text/javascript' responses. And the response Content-Type was 'text/html; charset=utf-8'. In Chrome the accepted types were 'application/json, text/javascript, /, text/javascript' and the response Content-Type was 'application/json; charset=utf-8'. I tried to force the content type in rails to 'text/javascript' format.json do render :json => @races.to_json, :content_type => 'text/javascript' end The content type is indeed changed in Chrome, but not in Firefox where it remains 'text/html'. Here is the code I used to trigger the ajax call. $.post( "/locator", params, function(data){...}, "json" ); Is there something I can do to make this work in Firefox? Thanks

  • Authentication Problem - not recognizing 'else' - Ruby on rails...

    - by bgadoci
    I can't seem to figure out what I am doing wrong here. I have implemented the Super Simple Authentication from Ryan Bates tutorial and while the login portion is functioning correctly, I can't get an error message and redirect to happen correctly for a bad login. Ryan Bates admits in his comments he left this out but can't seem to implement his recommendation. Basically what is happening is that when someone logs in correctly it works. When a bad password is entered it does the same redirect and flashes 'successfully logged in' thought they are not. The admin links do not show (which is correct and are the links protected by the <% if admin? %) but I need it to say 'failed login' and redirect to login path. Here is my code: SessionsController class SessionsController < ApplicationController def create if session[:password] = params[:password] flash[:notice] = 'Successfully logged in' redirect_to posts_path else flash[:notice] = "whoops" redirect_to login_path end end def destroy reset_session flash[:notice] = 'Successfully logged out' redirect_to posts_path end end ApplicationController class ApplicationController < ActionController::Base helper_method :admin? protected def authorize unless admin? flash[:error] = "unauthorized request" redirect_to posts_path false end end def admin? session[:password] == "123456" end helper :all # include all helpers, all the time protect_from_forgery # See ActionController::RequestForgeryProtection for details # end

  • Json HTTP Module stream issue

    - by Justin
    Hey, I have an HTTP Module that I use to clean up the JSON returned by my web service (see http://www.codeproject.com/KB/webservices/ASPNET_JSONP.aspx?msg=3400287#xx3400287xx for an example of this.) Basically it relates to calling cross-domain JSON web services from javascript. There is this JsonHttpModule which uses a JsonResponseFilter Stream class to write out the JSON and the overloaded Write method is supposed to wrap the name of the callback function around the JSON, otherwise the JSON errors out as needing a label. However, if the JSON is really long, the Write method in the Stream class is called multiple times, causing the callback function to incorrectly get inserted midway through the JSON. Is there a way in the Stream class to wrap the callback function around the stream at the end or to specify that it write all of the JSON in 1 Write method instead of in chunks?? Here's where it calls the JsonResponseFilter in the JsonHttpModule: public void OnReleaseRequestState(object sender, EventArgs e) { HttpApplication app = (HttpApplication)sender; if (!_Apply(app.Context.Request)) return; // apply response filter to conform to JSONP app.Context.Response.Filter = new JsonResponseFilter(app.Context.Response.Filter, app.Context); } Here's the Write method in the JsonResponseFilter Stream class that gets called multiple times: public override void Write(byte[] buffer, int offset, int count) { var b1 = Encoding.UTF8.GetBytes(_context.Request.Params["callback"] + "("); _responseStream.Write(b1, 0, b1.Length); _responseStream.Write(buffer, offset, count); var b2 = Encoding.UTF8.GetBytes(");"); _responseStream.Write(b2, 0, b2.Length); } Thanks for any help!

  • Debugging PHP Mail() and/or PHPMailer

    - by Agos
    Hi, I'm quite stuck with a problem sending mail from a PHP script. Some data: Shared hosting, no SSH access, only hosting provider panel PHP version 5.2.5 Last year I built a site which had no problems sending mail with the same hosting Let's say the domain is “domain.com” and my private address is “[email protected]” for anonimity's sake in the following code. Here's the code: <?php error_reporting(E_ALL); ini_set("display_errors", 1); $to = "[email protected]"; $subject = "Hi"; $body = "Test 1\nTest 2\nTest 3"; $headers = 'From: [email protected]' .

  • Ignoring a model with all blank fields in Ruby on Rails

    - by aguynamedloren
    I am trying to create multiple items (each with a name value and a content value) in a single form. The code I have is functioning, but I cannot figure out how to ignore items that are blank. Here's the code: #item.rb class Item < ActiveRecord::Base attr_accessible :name, :content validates_presence_of :name, :content end #items_controller.rb class ItemsController < ApplicationController def new @items = Array.new(3){ Item.new } end def create @items = params[:items].values.collect{|item|Item.new(item)} if @items.each(&:save!) flash[:notice] = "Successfully created item." redirect_to root_url else render :action => 'new' end end #new.html.erb <% form_tag :action => 'create' do %> <%@items.each_with_index do |item, index| %> <% fields_for "items[#{index}]", item do |f| %> <p> Name: <%= f.text_field :name %> Content: <%= f.text_field :content %> </p> <% end %> <% end %> <%= submit_tag %> <% end %> This code works when all fields for all items are filled out in the form, but fails if any fields are left blank (due to validations). The goal is that 1 or 2 items could be saved, even if others are left blank. I'm sure there is a simple solution to this, but I've been tinkering for hours with no avail. Any help is appreciated!

  • SQL Server lock/hang issue

    - by mattwoberts
    Hi, I'm using SQL Server 2008 on Windows Server 2008 R2, all sp'd up. I'm getting occasional issues with SQL Server hanging with the CPU usage on 100% on our live server. It seems all the wait time on SQL Sever when this happens is given to SOS_SCHEDULER_YIELD. Here is the Stored Proc that causes the hang. I've added the "WITH (NOLOCK)" in an attempt to fix what seems to be a locking issue. ALTER PROCEDURE [dbo].[MostPopularRead] AS BEGIN SET NOCOUNT ON; SELECT c.ForeignId , ct.ContentSource as ContentSource , sum(ch.HitCount * hw.Weight) as Popularity , (sum(ch.HitCount * hw.Weight) * 100) / @Total as Percent , @Total as TotalHits from ContentHit ch WITH (NOLOCK) join [Content] c WITH (NOLOCK) on ch.ContentId = c.ContentId join HitWeight hw WITH (NOLOCK) on ch.HitWeightId = hw.HitWeightId join ContentType ct WITH (NOLOCK) on c.ContentTypeId = ct.ContentTypeId where ch.CreatedDate between @Then and @Now group by c.ForeignId , ct.ContentSource order by sum(ch.HitCount * hw.HitWeightMultiplier) desc END The stored proc reads from the table "ContentHit", which is a table that tracks when content on the site is clicked (it gets hit quite frequently - anything from 4 to 20 hits a minute). So its pretty clear that this table is the source of the problem. There is a stored proc that is called to add hit tracks to the ContentHit table, its pretty trivial, it just builds up a string from the params passed in, which involves a few selects from some lookup tables, followed by the main insert: BEGIN TRAN insert into [ContentHit] (ContentId, HitCount, HitWeightId, ContentHitComment) values (@ContentId, isnull(@HitCount,1), isnull(@HitWeightId,1), @ContentHitComment) COMMIT TRAN The ContentHit table has a clustered index on its ID column, and I've added another index on CreatedDate since that is used in the select. When I profile the issue, I see the Stored proc executes for exactly 30 seconds, then the SQL timeout exception occurs. If it makes a difference the web application using it is ASP.NET, and I'm using Subsonic (3) to execute these stored procs. Can someone please advise how best I can solve this problem? I don't care about reading dirty data... Thanks

  • asp.net mvc and portal like functionality

    - by richard-heesbeen
    fHi, I need to build an site with some portal like functionality where an param in the request will indentify the portal. like so http:/domain/controller/action/portal Now my problem is if an portal doesn't exists there must be an redirect to an other site/page and an user can login in to one portal but if the user comes to an other portal the user must be redirected back to the login page for that portal. I have something working now, but i feel like there must be an central place in the pipeline to handle this. My current solution uses an custom action filter which checks the portal param and sees if the portal exists and checks if the user logged on in that portal (the portal the user logged on for is in the authentication cookie). I make my own IIndentiy and IPrincipal in the application_postauthentication event. I have 2 problems with my current approach: 1: It's not really enforced, i have to add the attributes to all controllers and/or actions. 2: The isauthenticated on an user isn't really working, i would like that to work. But for that i need to have access to the params of the route when i create my IPrincipal/IIndenty and i can't seem to find an correct place to do that. Hope someone can give me some pointers, Richard.

  • .NET Hashtable - "Same" key, different hashes

    - by Simon Lindgren
    Is it possible for two .net strings to have different hashes? I have a Hashtable with amongst others the key "path". When I loop through the elements in the table to print it, i can see that the key exists. When trying to looking it up however, there is no matching element. Debugging suggests that the string I'm looking for has a different hash than the one I'm supplying as the key. This code is in a Castle Monorail project, using brail as a view engine. The key I'm looking for is inserted by a brail line like this: UrlHelper.Link(node.CurrentPage.LinkText, {@params: {@path: "/Page1"}}) Then, in this method (in a custom IRoutingRule): public string CreateUrl(System.Collections.IDictionary parameters) { PrintDictionaryToLog(parameters); string url; if (parameters.Contains("path")) { url = (string)parameters["path"]; } else { return null; } } The key is printed to the log, but the function returns null. I didn't know this could even be a problem with .net strings, but I guess this is some kind of encoding issue? Oh, and this is running mono.

  • Why can't I build this Javascript object?

    - by Alex Mcp
    I have an object I'm trying to populate from another object (that is, iterate over a return object to produce an object with only selected values from the original). My code looks like this: var collect = {}; function getHistoricalData(username){ $.getJSON("http://url/" + username + ".json?params", function(data){ for (var i=0; i < data.length; i++) { console.log(i); collect = { i : {text : data[i].text}}; $("#wrap").append("<span>" + data[i].text + "</span><br />"); }; console.log(collect); }); } So I'm using Firebug for debugging, and here's what I know: The JSON object is intact console.log(i); is showing the numbers 1-20 as expected When I log the collect object at the end, it's structure is this: var collect = { i : {text : "the last iteration's text"}}; So the incrementer is "applying" to the data[i].text and returning the text value, but it's not doing what I expected, which is create a new member of the collect object; it's just overwriting collect.i 20 times and leaving me with the last value. Is there a different syntax I need to be using for assigning object members? I tried collect.i.text = and collect[i].text = and the error was that whatever I tried was undefined. I'd love to know what's going on here, so the more in-depth an explanation the better. Thanks!

  • Rails 3 get raw post data and write it to tmp file

    - by Andrew
    I'm working on implementing Ajax-Upload for uploading photos in my Rails 3 app. The documentation says: For IE6-8, Opera, older versions of other browsers you get the file as you normally do with regular form-base uploads. For browsers which upload file with progress bar, you will need to get the raw post data and write it to the file. So, how can I receive the raw post data in my controller and write it to a tmp file so my controller can then process it? (In my case the controller is doing some image manipulation and saving to S3.) Some additional info: As I'm configured right now the post is passing these parameters: Parameters: {"authenticity_token"=>"...", "qqfile"=>"IMG_0064.jpg"} ... and the CREATE action looks like this: def create @attachment = Attachment.new @attachment.user = current_user @attachment.file = params[:qqfile] if @attachment.save! respond_to do |format| format.js { render :text => '{"success":true}' } end end end ... but I get this error: ActiveRecord::RecordInvalid (Validation failed: File file name must be set.): app/controllers/attachments_controller.rb:7:in `create'

  • restrict documents for mapreduce with mongoid

    - by theBernd
    I implemented the pearson product correlation via map / reduce / finalize. The missing part is to restrict the documents (representing users) to be processed via a filter query. For a simple query like mapreduce(mapper, reducer, :finalize => finalizer, :query => { :name => 'Bernd' }) I get this to work. But my filter criteria is a little bit more complicated: I have one set of preferences which need to have at least one common element and another set of preferences which may not have a common element. In a later step I also want to restrict this to documents (users) within a certain geographical distance. Currently I have this code working in my map function, but I would prefer to separate this into either query params as supported by mongoid or a javascript function. All my attempts to solve this failed since the code is either ignored or raises an error. I did a couple of tests. A regular find like User.where(:name.in => ['Arno', 'Bernd', 'Claudia']) works and returns #<Mongoid::Criteria:0x00000101f0ea40 @selector={:name=>{"$in"=>["Arno", "Bernd", "Claudia"]}}, @options={}, @klass=User, @documents=[]> Trying the same with mapreduce User.collection. mapreduce(mapper, reducer, :finalize => finalizer, :query => { :name.in => ['Arno', 'Bernd', 'Claudia'] }) fails with `serialize': keys must be strings or symbols (TypeError) in bson-1.1.5 The intermediate query parameter looks like this :query=>{#<Mongoid::Criterion::Complex:0x00000101a209e8 @key=:name, @operator="in">=>["Arno", "Bernd", "Claudia"]} and at least @operator looks a bit weird to me. I'm also uncertain if the class name can be omitted. BTW - I'm using mongodb 1.6.5-x86_64, and the mongoid 2.0.0.beta.20, mongo 1.1.5 and bson 1.1.5 gems on MacOS. What am I doing wrong? Thanks in advance.

  • i18n redirection breaks my tests ....

    - by Mike
    I have a big application covered by more than a thousand tests via rspec. We just made the choice to redirect any page like : / /foo /foo/4/bar/34 ... TO : /en /en/foo /fr/foo/4/bar/34 .... So I made a before filter in application.rb like so : if params[:locale].blank? headers["Status"] = "301 Moved Permanently" redirect_to request.env['REQUEST_URI'].sub!(%r(^(http.?://[^/]*)?(.*))) { "#{$1}/#{I18n.locale}#{$2}" } end It's working great but ... It's breaking a lot of my tests, ex : it "should return 404" do Video.should_receive(:failed_encodings).and_return([]) get :last_failed_encoding response.status.should == "404 Not Found" end To fix this test, I should do : get :last_failed_encoding, :locale => "en" But ... seriously I don't want to fix all my test one by one ... I tried to make the locale a default parameter like this : class ActionController::TestCase alias_method(:old_get, :get) unless method_defined?(:old_get) def get(path, parameters = {}, headers = nil) parameters.merge({:locale => "fr"}) if parameters[:locale].blank? old_get(path, parameters, headers) end end ... but couldnt make this work ... Any idea ??

  • Receiving client-event on a GtkWindow

    - by fret
    I'm trying to send and receive a client-event using a GtkWindow on the win32 platform. The sending code looks like this: GtkWidget *Wnd; GdkNativeWindow Hnd = #ifdef WIN32 GDK_WINDOW_HWND(Wnd->window); #else GDK_WINDOW_XWINDOW(Wnd->window); #endif GdkEvent *Event = gdk_event_new(GDK_CLIENT_EVENT); // fill out Event params gdk_event_send_client_message(Event, Hnd); Receiving code looks like this: static gboolean MyClientEvent(GtkWidget *widget, GdkEventClient *ev, MyWnd *Wnd) { // breakpoint here... return TRUE; } GtkWidget *Wnd = gtk_window_new(GTK_WINDOW_TOPLEVEL); g_signal_connect( G_OBJECT(Wnd), "client-event", G_CALLBACK(MyClientEvent), this); gtk_widget_add_events(Wnd, GDK_ALL_EVENTS_MASK); I used Spy++ to see the message getting sent, so I know the sending side is ok. The receiving side however doesn't get the client-event. I was expecting my breakpoint in the callback to trigger... but it doesn't. I'm not even sure if a GtkWindow can receive a client-event... from past experience on X11 I thought it was pretty much the same as any other GtkWidget in that respect. Maybe on the win32 platform it's kinda different. But still I'd like to be able to get this working.

  • Does Android XML Layout's 'include' Tag Really Work?

    - by Eric Burke
    I am unable to override attributes when using <include> in my Android layout files. When I searched for bugs, I found Declined Issue 2863: "include tag is broken (overriding layout params never works)" Since Romain indicates this works in the test suites and his examples, I must be doing something wrong. My project is organized like this: res/layout buttons.xml res/layout-land receipt.xml res/layout-port receipt.xml The buttons.xml contains something like this: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="horizontal"> <Button .../> <Button .../> </LinearLayout> And the portrait and landscape receipt.xml files look something like: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical"> ... <!-- Overridden attributes never work. Nor do attributes like the red background, which is specified here. --> <include android:id="@+id/buttons_override" android:background="#ff0000" android:layout_width="fill_parent" layout="@layout/buttons"/> </LinearLayout> What am I missing?

  • How do I reject if exists? for non-nested attributes?

    - by GoodGets
    Currently my controller lets a user submit muliple "links" at a time. It collects them into an array, creates them for that user, but catches any errors for the User to go back and fix. How can I ignore the creation of any links that already exist for that user? I know that I can use validates_uniqueness_of with a scope for that user, but I'd rather just ignore their creation completely. Here's my controller: @links = params[:links].values.collect{ |link| current_user.links.create(link) }.reject { |p| p.errors.empty? } Each link has a url, so I thought about checking if that link.url already exists for that user, but wasn't really sure how, or where, to do that. Should I tack this onto my controller somehow? Or should it be a new method in the model, like as in a before_validation Callback? (Note: these "links" are not nested, but they do belong_to :user.) So, I'd like to just be able to ignore the creation of these links if possible. Like if a user submits 5 links, but 2 of them already exist for him, then I'd just like for those 2 to be ignored, while the other 3 are created. How should I go about doing this?

  • Error when calling SQL SP via LINQ

    - by PaulC
    Newbie problem: I have a SQL SP with ten parameters (eight input, two output) but when I attempt to call it via LINQ from code I get the following error message: "The best overloaded method match for 'DataClassesDataContext.ST_CR_CREATE_CASE_BASIS(string, string, string, string, System.DateTime?, string, string, string, ref int?, ref int?)' has some invalid arguments". The params with ? appear to be unrecognized, but I'm baffled: the data types match the SQL types, the number of parameters match, the other parmeters don't exhibit the same behaviour. Can anyone tell me what's going on? Thanks in advance. -- SQL SP: create procedure ST_CR_CREATE_CASE_BASIS @p_Pers_No nvarchar (50), @p_Subject nvarchar (255), @p_RQ_XML nvarchar(max), @p_RQ_XSL nvarchar(max), @p_Date_Submit smalldatetime, @p_User_ID_Submit nvarchar (255), @p_RQ_Status nvarchar (50), @p_User_ID_OnBehalf nvarchar (255), @p_Case_Number int output, @p_RQ_ID int output as begin -- ... etc.; the SP works fine when called from SSMS The code-behind proc from the aspx page looks like this: protected void cmdSubmit_Click(object sender, EventArgs e) { using (DataClassesDataContext vDataCont = new DataClassesDataContext()) { Int32 vNewCaseNr; Int32 vNewReqNr; DateTime vNow = System.DateTime.Now; vDataCont.ST_CR_CREATE_CASE_BASIS("101", "Test Subject Late Wed", null, null, vNow , "101", "1", "101", ref vNewCaseNr, vNewReqNr); } }

  • Is a "factory" method the right pattern?

    - by jdt141
    Hey all - So I'm working to improve an existing implementation. I have a number of polymorphic classes that are all composed into a higher level container class. The problem I'm dealing with at the moment is that the higher level container class, well, sucks. It looks something like this, which I really don't have a problem with (as the polymorphic classes in the container should be public). My real issue is the constructor... /* * class1 and class 2 derive from the same superclass */ class Container { public: boost::shared_ptr<ComposedClass1> class1; boost::shared_ptr<ComposedClass2> class2; private: ... } /* * Constructor - builds the objects that we need in this container. */ Container::Container(some params) { class1.reset(new ComposedClass1(...)); class2.reset(new ComposedClass2(...)); } What I really need is to make this container class more re-usable. By hard-coding up the member objects and instantiating them, it basically isn't and can only be used once. A factory is one way to build what I need (potentially by supplying a list of objects and their specific types to be created?) Other ways to get around this problem? Seems like someone should have solved it before... Thanks!

  • Have error message show when form is created through AJAX

    - by Railslearner
    I have a page called /add that you can add a Dog on and the form is in its own partial. I'm using Simple Form and Twitter Bootstrap. I added the files for the main Bootstrap but use a gem for simple_form to work with it just so you know. DogsController # new.js.erb (deleted new.html.erb) def new @dog = Dog.new respond_to do |format| format.js end end # create.js.erb def create @dog = current_user.dogs.new(params[:dog]) respond_to do |format| if @dog.save format.html { redirect_to add_url, notice: 'Dog was successfully added.' } format.json { render json: @dog, status: :created, location: @dog} format.js else format.html { render 'pages/add' } format.json { render json: @dog.errors, status: :unprocessable_entity } end end end dogs/_form.html.erb <%= simple_form_for(@dog, :remote => true) do |f| %> <%= render :partial => "shared/error_message", :locals => { :f => f } %> <%= f.input :name %> <%= f.button :submit, 'Done' %> <% end %> This line: <%= render :partial => "shared/error_message", :locals => { :f => f } %> Is for bootstrap so it renders the errors html correctly. PagesController def add respond_to do |format| format.html end end pages/add.html.erb <div id="generate-form"> </div> dogs/new.js.erb $("#generate-form").html("<%= escape_javascript(render(:partial => 'dogs/form', locals: { dog: @dog })) %>"); Now how would I get this to render the error partial as if it was still on my dogs/new.html.erb since its being created through AJAX? I don't need client side validations do I?
