  • Devise and cancan gems: has_many association

    - by tiktak
    I use devise and cancan gems and have simple model association: user has_many subscriptions, subscription belongs_to :user. Have following SubscriptionsController: class SubscriptionsController < ApplicationController load_and_authorize_resource :user load_and_authorize_resource :subscription, through: :user before_filter :authenticate_user! def index @subscriptions = @user.subscriptions.paginate(:page => params[:page]).order(:created_at) end #other actions end And Cancan Ability.rb: class Ability include CanCan::Ability def initialize(user) user ||=User.new can [:index, :show], [Edition, Kind] if user.admin? can :manage, :all elsif user.id can [:read, :create, :destroy, :pay], Subscription, user_id: user.id can [:delete_from_cart, :add_to_cart, :cart], User, id: user.id end end end The problem is that i cannot use subscriptions actions as a user but can as a admin. And have no problems with UsersController. When i delete following lines from SubscriptionsController: load_and_authorize_resource :user load_and_authorize_resource :subscription, through: :user before_filter :authenticate_user! Have no problems at all. So the issue in these lines or in Ability.rb. Any suggestions?

  • OpenAL device, buffer and context relationship

    - by Markus
    I'm trying to create an object oriented model to wrap OpenAL and have a little problem understanding the devices, buffers and contexts. From what I can see in the Programmer's Guide, there are multiple devices, each of which can have multiple contexts as well as multiple buffers. Each context has a listener, and the alListener*() functions all operate on the listener of the active context. (Meaning that I have to make another context active first if I wanted to change it's listener, if I got that right.) So far, so good. What irritates me though is that I need to pass a device to the alcCreateContext() function, but none to alGenBuffers(). How does this work then? When I open multiple devices, on which device are the buffers created? Are the buffers shared between all devices? What happens to the buffers if I close all open devices? (Or is there something I missed?)

  • Symfony2 Setting a default choice field selection

    - by Mat
    I am creating a form in the following manner: $form = $this->createFormBuilder($breed) ->add('species', 'entity', array( 'class' => 'BFPEduBundle:Item', 'property' => 'name', 'query_builder' => function(ItemRepository $er){ return $er->createQueryBuilder('i') ->where("i.type = 'species'") ->orderBy('i.name', 'ASC'); })) ->add('breed', 'text', array('required'=>true)) ->add('size', 'textarea', array('required' => false)) ->getForm() How can I set a default value for the species listbox? Thank you for your response, I apologise, I think I should rephrase my question. Once I have a value that I retrieve from the model, how do I set that value as SELECTED="yes" for the corresponding value in the species choice list? So, that select option output from the TWIG view would appear like so: <option value="174" selected="yes">Dog</option>

  • Best Ruby ORM for Wrapping around Legacy SQL Server Database?

    - by Technocrat
    Hi. I found this answer and it sounds like almost exactly what I'm doing. I have heard mixed answers about whether or not datamapper can support SQL Server through dataobjects. Basically, we have an app that uses a consistently structured database, consistently named tables, etc in SQL Server. We're making all kinds of tools and stuff that have to interact with it, some of them remotely and so I decided that we need to create some common, simple access point to do read/write operations on the SQL Server app since it's API is all C# and other things I despise. Now my question is if anyone has any examples or projects they know of where a ruby ORM can essentially create models for another application's legacy database by defining the conventions of each model's pkeys, fkeys, table names, etc. Sequel is the only ORM I've used with SQL Server but never to do anything quite like this. Any suggestions?

  • Implementing Qt File Dialog with a Different File System Library (boost)

    - by knight
    Hi, I am writing an application which requires me to use another file system and file engine handlers and not the qt's default ones. Basically what I want to be able to do is to use qt's file dialog but have an underlying file system handler (for example built using boost file system library) of mine handling all the operations with regards to file and directory operations within that dialog. I have already written a custom file engine which handles some of the operations but I am now stuck with Qt's file system model and the file system watcher engine, as I need to have the signals transmitted for this custom file engine. Seems like I have a daunting task ahead. Am I heading in the right direction? Is there any other simpler way that I could implement this? Can anyone give me any idea on how to proceed. I was thinking of looking into proxy models but not sure if that would work. Thanks in advance for any help.

  • validate constructor arguments or method parameters with annotations, and let them throw an exceptio

    - by marius
    I am validating constructor and method arguments, as I want to the software, especially the model part of it, to fail fast. As a result, constructor code often looks like this public MyModelClass(String arg1, String arg2, OtherModelClass otherModelInstance) { if(arg1 == null) { throw new IllegalArgumentsException("arg1 must not be null"); } // further validation of constraints... // actual constructor code... } Is there a way to do that with an annotation driven approach? Something like: public MyModelClass(@NotNull(raise=IllegalArgumentException.class, message="arg1 must not be null") String arg1, @NotNull(raise=IllegalArgumentException.class) String arg2, OtherModelClass otherModelInstance) { // actual constructor code... } In my eyes this would make the actual code a lot more readable. In understand that there are annotations in order to support IDE validation (like the existing @NotNull annotation). Thank you very much for your help.

  • jQuery featured content slider

    - by azz0r
    Hello, I have a content area that loops through divs and shows there content. I'm having trouble making it display the initial content, unfortunately it waits 5000 milliseconds before triggering the very first content area to display. Anyone spot an easy way to make it display the initial area, then slide to the next area and do them at 5000 milliseconds.

  • iphone: Accessing Code for Elements Created in Interface Builder

    - by user362685
    I am attempting to create a basic tab-bar application using interface builder. I create a new project in Xcode selecting tab bar application. My question is how can I access the code that instantiates and pushes each of the views when the tab bar buttons are pressed? I would imagine that would be done by the tab bar controller, however when I write the class file from interface builder (filewrite class files), it just creates a blank generic TabBarController.h/TabBarController.m without the methods for pushing each of the views associated with the tab bar elements. I ask this because I would like to pass each view controller a reference to the data model when they are instantiated. Any help would be greatly appreciated, thanks.

  • Invoicing vs Quoting or Estimating

    - by FreshCode
    If invoices can be voided, should they be used as quotations? I have an Invoices tables that is created from inventory associated with a Job or Order. I could have a Quotes table as a halfway-house between inventory and invoices, but it feels like I would have duplicate data structures and logic just to handle an "Is this a quote?" bit. From a business perspective, quotes are different from invoices: a quote is sent prior to an undertaking and an invoice is sent once it is complete and payment is due, but how to represent this in my repository and model. What is an elegant way to store and manage quotes & invoices in a database? Edit: indicated Job === Order for this particular instance.

  • Difficulty to start up with basic unit test (Sample from my book -- SportsStore)

    - by Richard77
    Hello, I'm really new in TDD and, actually, I'm trying to follow the sample from my book (SportsStore -- Pro ASP.NET MVC Framework/Steve Sanderson/APRESS). I'm on pages 103-105. Although there are more on this, as new to all of this, I'm concerned with the following statements. ProductsController controller = new ProductsController(repository); var result = controller.List(2); //... regarding the above statements, when I write this (as in the book), var products = result.ViewData.Model as IList<Product>; I get a compiler error "System.Web.MVC.ActionResult" does not contain a definition for ViewData ..." But, when I remove the List() from the statement, then the compiler error disapear. var result = controller.List(2);//Doesn't work var result = controller;//It works Is something wrong there? I checked Apress website for that book, but there is nothing listed as Errata or issue. So I'm really lost. Thanks for helping

  • How to deserialize from json to ActiveRecord objects with associations?

    - by Carmine Paolino
    In my Rails application there is a model that has some has_one associations (this is a fabricated example): class Person::Admin < ActiveRecord::Base has_one :person_monthly_revenue has_one :dude_monthly_niceness accepts_nested_attributes_for :person_monthly_revenue, :dude_monthly_niceness end class Person::MonthlyRevenue < ActiveRecord::Base belongs_to :person_admin end class Dude::MonthlyNiceness < ActiveRecord::Base belongs_to :person_admin end The application talks to a backend that computes some data and returns a piece of JSON like this: { "dude_monthly_niceness": { "february": 1.1153232569518972, "october": 1.1250217200558268, "march": 1.3965786869658541, "august": 1.6293418014601631, "september": 1.4062771500697835, "may": 1.7166279693955291, "january": 1.0086401628086725, "june": 1.5711510228365859, "april": 1.5614525597326563, "december": 0.99894169970474289, "july": 1.7263264324994585, "november": 0.95044938418509506 }, "person_monthly_revenue": { "february": 10.585596551505297, "october": 10.574823016656749, "march": 9.9125274764852787, "august": 9.2111604702328922, "september": 9.7905249446675153, "may": 9.1329712474607962, "january": 10.479614016604238, "june": 9.3710235926961936, "april": 9.5897372624830304, "december": 10.052587677671438, "july": 8.9508877843925561, "november": 10.925339756096172 }, } To deserialize it, I use ActiveRecord's from_json, but instead of a Person::Admin object with all the associations in place, I get this error: >> Person::Admin.new.from_json(json) NameError: uninitialized constant Person::Admin::DudeMonthlyNiceness Am I doing something wrong? Is there a better way to deserialize data? (I can modify the backend easily)

  • Assigning a material in Blender with a script

    - by Narcolapser
    Question: How do you assign a material with a script to an object in blender? Info: I have this script to import a proprietary model type of mine that is basically a star map with object consisting of a single vertex. in order to make them look like stars and be visible they are all going to have a halo material assigned to them. I'm figuring out how to make this material and give it the values just fine, but I can't seem to get it to assign. I tried the most obvious thing which was: objectName.setMaterial(materialName) but that did nothing. and when i would take an object that had a material and call the getMaterial function on it, it would return nothing. there is something I'm missing here, can some one shed some light on it? Thanks. ~TA

  • Inlines in Django Admin

    - by Oli
    I have two models, Order and UserProfile. Each Order has a ForeignKey to UserProfile, to associate it with that user. On the django admin page for each Order, I'd like to display the UserProfile associated with it, for easy processing of information. I have tried inlines: class UserInline(admin.TabularInline): model = UserProfile class ValuationRequestAdmin(admin.ModelAdmin): list_display = ('address1', 'address2', 'town', 'date_added') list_filter = ('town', 'date_added') ordering = ('-date_updated',) inlines = [ UserInline, ] But it complains that UserProfile "has no ForeignKey to" Order - which it doesn't, it's the other way around. Is there a way to do what I want?

  • Range validation not working properly in MVC3

    - by Colin Desmond
    I am generating data validation javascript in an Asp.Net MVC 3 application with the following code [DisplayName("Latitude Degrees")] [Range(0, 90, ErrorMessage = "Latitude degrees must be between {1} and {2}")] public Int32? LatitudeDegrees { get; set; } on a view model. When it was MVC2 this worked just fine, if I entered a value outside of 0-90 in the textbox I got the validation warnings. Since I moved the application to MVC 3, whenever I put any value into the texbox, legal or illegal I get the validation error appear next to it. I have EnableClientValidation set to true and UseUnobtrusiveJavascript is off (nothing in web.config or the views to turn it on).

  • How do I create multiple submit buttons for the same form in Rails?

    - by Angela
    I need to have multiple submit buttons. I have a form which creates an instance of Contact_Call. One button creates it as normal. The other button creates it but needs to have a different :attribute value from the default, and it also needs to set the attribute on a different, but related model used in the controller. How do I do that? I can't change the route, so is there a way to send a different variable that gets picked up by [:params]? And if I do then, what do I do in the controller, set up a case statement?

  • Rails 3 query in multiple date ranges

    - by NeoRiddle
    Suppose we have some date ranges, for example: ranges = [ [(12.months.ago)..(8.months.ago)], [(7.months.ago)..(6.months.ago)], [(5.months.ago)..(4.months.ago)], [(3.months.ago)..(2.months.ago)], [(1.month.ago)..(15.days.ago)] ] and a Post model with :created_at attribute. I want to find posts where created_at value is in this range, so the goal is to create a query like: SELECT * FROM posts WHERE created_at BETWEEN '2011-04-06' AND '2011-08-06' OR BETWEEN '2011-09-06' AND '2011-10-06' OR BETWEEN '2011-11-06' AND '2011-12-06' OR BETWEEN '2012-01-06' AND '2012-02-06' OR BETWEEN '2012-02-06' AND '2012-03-23'; If you have only one range like this: range = (12.months.ago)..(8.months.ago) we can do this query: Post.where(:created_at => range) and query should be: SELECT * FROM posts WHERE created_at BETWEEN '2011-04-06' AND '2011-08-06'; Is there a way to make this query using a notation like this Post.where(:created_at => range)? And what is the correct way to build this query? Thank you

  • Nested Select in Rails

    - by James
    I am working on a Rails application which uses categories for items. My category model is self-joined so that categories can be nested: class Category < ActiveRecord::Base has_many :items # Self Join (categories can have subcategories) has_many :subcategories, :class_name => "Category", :foreign_key => "parent_id" belongs_to :parent, :class_name => "Category" ... end I have a form which allows a user to create an item which currently lists all categories in a select, but they are all listed together: <%= f.label :category_id %> <%= select :item, :category_id, Category.all.collect {|c| [ c.title, c.id ]} %> So the select looks something like this: Category1 Category2 Category3BelongsTo2 Category4BelongsTo1 But what I want is: Category1 - Category4BelongsTo1 Category2 - Category3BelongsTo2 Is there a helper for this (which would be awesome!)? If not, how could I accomplish this? Thanks!

  • Hibernate Criteria: Return different entity type than rooted entity?

    - by Gilean
    I have entities similar to: ProductLine: id, name ProductLineContents: content_id, product_line_id Content: id, text, updated_time What I'd like to do is: for each product line, get the latest content (so if theres two content entries associated to one product line, the latest updated_time is rturned, and if one content item is associated to two product lines, it is returned twice). Something similar to: select content.* from productline inner join productlinecontents inner join content; However I can't seem to figure out how to have Hibernate Criteria return a different entity than the original one it was created with. So if I wanted to start the criteria at the product line with createCriteria(ProductLine.class) along with the proper joins, then it only returns ProductLine objects, but I need Content objects. What's the best way to accomplish this? The actual data model is much more complex and can't be modified

  • How do I query/filter a to-many relationship in Core Data

    - by Kris Bixler
    I have Customer, Event and Address objects in my data model. Both Customer and Address have a one-to-many relationship to Event. I can get the distinct list of addresses for a customer's events for by doing this: NSSet *addressSet = [customer valueForKeyPath:@"events.address"]; For the part of the UI I'm working on now, I need to display the address from the most recent event prior to now that has an address. I'm starting to go down the path of creating a NSFetchRequest, setting it's entity, sort descriptors, predicate and then looping through the results, but it seems like a lot of code. Am I missing some obvious way of filtering/sorting on the "events" relationship of the Customer object or is creating the NSFetchRequest the best solution?

  • Plastic SCM vs. Mercurial? Need Source Control for Visual Studio 2005 on Windows 7

    1) Has anyone used Plastic SCM? Is it reliable? 2) How does it compare with Mercurial? (It seems like this is a good candidate for DVCS on Windows. I tried Git and really didn't like it.) 3) I really like TortoiseSVN. I like a central model because of the piece of mind that if it's in the respository it's "safe" and tracked. Here is the question: Is the excitement over distributed version control (DVCS) worth the hype? My environment: Windows 7 Windows development (Dev.
