  • How to force reload all vendor/plugins in rails 2.3 (development mode)

    - by tsdbrown
    We have an application with a app/model that references another model stored in a plugin. When the app/model level is reloaded on the second and further requests and that relies on our model in vendor/plugins/... (which stays loaded) it fails (can't dup nil class). We've tried setting config.reload_plugins = true in the development.rb but this doesn't seem to do it. Does anybody know a way to handle this?

  • Using MongoDB with Ruby On Rails and the Mongomapper plugin

    - by Micke
    Hello, i am currently trying to learn Ruby On Rails as i am a long-time PHP developer so i am building my own community like page. I have came pritty far and have made the user models and suchs using MySQL. But then i heard of MongoDB and looked in to it a little bit more and i find it kinda nice. So i have set it up and i am using mongomapper for the connection between rails and MongoDB. And i am now using it for the News page on the site. I also have a profile page for every User which includes their own guestbook so other users can come to their profile and write a little message to them. My thought now is to change the User models from using MySQL to start using MongoDB. I can start by showing how the models for each User is set up. The user model: class User < ActiveRecord::Base has_one :guestbook, :class_name => "User::Guestbook" The Guestbook model model: class User::Guestbook < ActiveRecord::Base belongs_to :user has_many :posts, :class_name => "User::Guestbook::Posts", :foreign_key => "user_id" And then the Guestbook posts model: class User::Guestbook::Posts < ActiveRecord::Base belongs_to :guestbook, :class_name => "User::Guestbook" I have divided it like this for my own convenience but now when i am going to try to migrate to MongoDB i dont know how to make the tables. I would like to have one table for each user and in that table a "column" for all the guestbook entries since MongoDB can have a EmbeddedDocument. I would like to do this so i just have one Table for each user and not like now when i have three tables just to be able to have a guestbook. So my thought is to have it like this: The user model: class User include MongoMapper::Document one :guestbook, :class_name => "User::Guestbook" The Guestbook model model: class User::Guestbook include MongoMapper::EmbeddedDocument belongs_to :user many :posts, :class_name => "User::Guestbook::Posts", :foreign_key => "user_id" And then the Guestbook posts model: class User::Guestbook::Posts include MongoMapper::EmbeddedDocument belongs_to :guestbook, :class_name => "User::Guestbook" But then i can think of one problem.. That when i just want to fetch the user information like a nickname and a birthdate then it will have to fetch all the users guestbook posts. And if each user has like a thousand posts in the guestbook it will get really much to fetch for the system. Or am i wrong? Do you think i should do it any other way? Thanks in advance and sorry if i am hard to understand but i am not so educated in the english language :)

  • Do you have ideas for a workaround for this Known bug in Visual Studio 2010's addIn model ?

    - by Jesper
    When developing AddIns for Visual Studio 2010 the following line fails: CommandBarEvents handler = (EnvDTE.CommandBarEvents)m_VSStudio.DTE.Events.get_CommandBarEvents(popup); Update: Forgot to tell that m_VSStudio is of the type DTE2 Where popup is of the type CommandBarPopup (for the type CommandBarControl it works though) The line fails with this Exception: System.Runtime.InteropServices.COMException (0x80020003): Member not found. (Exception from HRESULT: 0x80020003 (DISP_E_MEMBERNOTFOUND)) The exact same line worked in Visual Studio 2008. The purpose of the line is to get a handler which handles clickevents, when one clicks the Popup. After som searching I found this link: http://connect.microsoft.com/VisualStudio/feedback/details/524335/events-get-commandbarevents-exception-on-submenus-reproducible-bug-addin Which basicly states that it is a known bug, which will not be fixed, because there is a workaround. But unfortunately it does not state the workaround :( I would be extremely pleased if anybody has a great idea for a workaround ? The reason why I want to listen to the click events is because I want to show or hide the submenuitems (CommandBarControl) given some condition, when one clicks a menu (CommandBarPopup). So a workaround that uses something else than the click event would also be appreciated.

  • How can I create a graph of Nginx responses by HTTP status code?

    - by rmh
    I'm looking to create a graph somewhat similar to this: But instead of graphing requests, graph responses, with a line for each HTTP response code (200 OK, 404 Not Found, 500 Server Error, etc). Creating the graph isn't the issue (use RRDtool, Server Density or something similar), but how can I best retrieve this information from Nginx? Unfortunately, this data isn't available on the page generated by NginxHttpStubStatusModule. If it was, this would be pretty easy.

  • ant compile problem

    - by senzacionale
    If I start ant compile in JDeveloper all classes are compiled successfully and copied to the classes folder. But if I run ant compile from console then no classes are copied to the classes folder. Does anyone know why? Maybe the problem is with: build.compiler=oracle.ojc.ant.taskdefs.OjcAdapter? build.properties: javac.debug=on oracle.home=C:/Oracle/jdevstudio10133 build.compiler=oracle.ojc.ant.taskdefs.OjcAdapter output.dir=classes javac.deprecation=on javac.nowarn=off package.name=KIS dest.dir=C:/Projekti/Projekt ANT/CVS src.dir=src view.dir=View model.dir=Model modelirc2000.dir=ModelIRC2000 build.xml for compile <target name="compile" description="Compile Java source files" depends="init"> <javac destdir="${dest.dir}/${package.name}/${model.dir}/${output.dir}" classpathref="classpath" debug="${javac.debug}" nowarn="${javac.nowarn}" deprecation="${javac.deprecation}" encoding="Cp1250" source="1.5" target="1.5"> <src path="${dest.dir}/${package.name}/${model.dir}/${src.dir}"/> <exclude name="irc/kis/model/dm/entity/common/ZnanjeImplMsgBundle.java/"/> <exclude name="META-INF/"/> <exclude name="irc/kis/view/"/> <exclude name="irc/kis/model/zap/view/vp/"/> </javac> </target> <target name="copy" description="Copy files to output directory" depends="init"> <patternset id="copy.patterns"> <include name="**/*.gif"/> <include name="**/*.jpg"/> <include name="**/*.jpeg"/> <include name="**/*.png"/> <include name="**/*.properties"/> <include name="**/*.xml"/> <include name="**/*-apf.xml"/> <include name="**/*.ejx"/> <include name="**/*.xcfg"/> <include name="**/*.cpx"/> <include name="**/*.dcx"/> <include name="**/*.wsdl"/> <include name="**/*.ini"/> <include name="**/*.tld"/> <include name="**/*.tag"/> <include name="**/*.jpx"/> </patternset> <copy todir="${dest.dir}/${package.name}/${model.dir}/${output.dir}"> <fileset dir="${dest.dir}/${package.name}/${model.dir}/${src.dir}"> <patternset refid="copy.patterns"/> </fileset> </copy> </target>

  • Can I use the TFS Object Model to interact with TFS via F#?

    - by Russell
    I am looking for some quick ways to do some (more) complex queries across who has what checked out and things like that (eg. which files have 1 person checked out). I have been learning F# over the last year or so and saw the potential to use both the functional aspects of F# to quickly create some useful and more complex TFS commands. I was wondering if anyone else has done this, or have any ideas on how I would go about doing this. PS: I am using TFS 2005. Thanks Russell

  • Call task more than once in Rails 3 generator

    - by balexand
    I'm writing a Rails 3 generator that creates two different models. Here's a very simplified example of what I'm trying to do: def my_generator_task invoke "model", ["foo"] invoke "model", ["bar"] end The problem is that the Thor invoke method only invokes a task once, so the second call to the "model" task never happens and the "bar" model is never created. Does anyone know an elegant way to accomplish this, preferably in a way that doesn't break the ability to run "rails destroy" with the generator?

  • git, egit, submodules, and symlinks -- how should shared sub-projects be handled in eclipse?

    - by Autophil
    Question: what's the best way to handle sub-projects in eclipse when using git for SCM? Here's the situation. I have a few git projects with a directory structure layed out more or less like this: simpleproj app www admin demo lib model orm view model user blah ... storeproj app www about mobile fbapp lib model orm view model user message cart product merchant Each directory in "lib" contains a separate project, either created in-house or forked, all of which use git for source control. So I figured I should make them submodules of my projects, right? Well, we've been moving toward eclipse + egit, because some of our windows guys not used to a CLI need something they can use without being scared of screwing things up. Anyway, the problem is, egit doesn't support submodules. So, my solution has been a rather crude one involving symlinks... lets say my directory structure on my dev box is generally layed out like this: ~/projects/ bigproj .git app lib model (- ~/lib/model/src/) orm (- ~/lib/orm/src/) neatproj .git app lib view (- ~/lib/view/src/) oldproj .git app lib orm (- ~/lib/orm/src/) ~/lib/ model .git src README.md orm .git src COPYING view .git src ...the symlinks link to a subdirectory of the directory containing the git repo, so eclipse doesn't get confused, and everything sort of works. On my machine, I can update the libs from anywhere and all projects will be updated (needing to be committed again of course). Each project stores a separate copy of the contents of the symlinked directories within "lib" -- but only when staged from within eclipse. After committing from eclipse and moving back to the CLI, git sees that a bunch of files have been removed and a few symlinks have been created. Of course this is acceptable also, probably more so than keeping a separate history of the libs for each project... but eclipse and CLI git obviously need to be on the same page so tons of files aren't vanishing and reappearing. So this brings me to my question. I'd like to know how to either: get eclipse+egit to see the symlinks as symlinks if git will somehow handle them properly*, or get the CLI git to treat them as non-symlinks. Or, if there's a better way to do this, I'm all ears. Hope this all made sense! :D Note: tried to tag this as git-submodules, but was not allowed :( * should I make them relative or absolute? Either way it's a mess. Also will symlinks will work on windows? i know there's something similar but you need a 3rd party tool to manage them AFAIK, i doubt these would translate well.

  • How do I add a condition to all ActiveRecords Queries for a particular model?

    - by Kyle West
    I am using the sentient_user gem to have access to the current_user object in my application. I want to override the default ActiveRecordBase queries to scope them to the current user. For instance, I don't want my users looking at, deleting, modifying other user's orders. I feel like I should be able to override a single (or couple) ActiveRecordBase methods to accomplish this, but I don't know which or how. Thanks in advance.

  • C++ (And other languages) - Learning from source code examples.

    - by Gabe
    I found that the most effective way for me to learn html and css was to simply find a site, right click, view the source code, and see how it worked. I'm in the process of learning c++ and I think examples/source code to look through would help me a good deal. So, how can I do this? Are there online sites that serve this purpose? Any other recommendations on learning would be great, too.

  • How do you handle the deletion of your model working with ViewModels and keeping them in sync ?

    - by Lisa
    Hello, these could be my entity relations: 1 Pupil has 1 Chair 1 Pupil has N Documents 1 Pupil has N Marks 1 Pupil has N IncidentReports etc... So with that sample I get 4 IEnumerable from my database put each into an ObservableCollection. Now I have 4 different Views each bound to one of those 4 collections. Lets assume I delete a single PupilViewModel in the AdministrationController which is the only View where I can delete a PupilViewModel. Now I have to inform 3 other Controller and their ObservableCollections about the one deleted PupilViewModel to keep the whole application synchronized... thats stupid somehow. Do you have any good advice on that scenario? AND it gets even worse. If I delete a schoolclass I have to sync the pupils everywhere AND the documents or incidentreports or marks... gush... o_O

  • How to tell if two exe's are the same code-wise?

    - by yumcious
    Is there a way to detect whether two EXE's (compiled from VS.Net 2008 for C++/MFC) do not have any code-level changes between them i.e. for purposes of knowing that there have been no statement changes. This is for compliance purposes when my vendor ships me an exe, ostensibly with no changes made to the code since the last time we tested it. Is there a tool to check that this is so? Cheers
