  • Rails - column not found for defined 'has_many' relationship

    - by Guanlun
    I define a Post class which can link or be linked to multiple posts. To do this I added a PostLink class which specifies post_to and post_from. I generated the PostLink class by rails g model post_link from_post:integer to_post:integer and of course rake db:migrate, and added belongs_to :from_post, :class_name => 'Post' belongs_to :to_post, :class_name => 'Post' to the class. And I also have has_many :post_links in my Post class. I ran rails console and Post.new.post_links and got nil printed out, which is expected. However after I save a Post using p = Post.new p.save and then run p.post_links, it prints out the following error message: SQLite3::SQLException: no such column: post_links.post_id: SELECT "post_links".* FROM "post_links" WHERE "post_links"."post_id" = 1 So anybody know why after saving it to the database post_link can not be accessed?

  • Rails Devise: How to access sign up page after signed in?

    - by Junior rails programmer
    hi All, I am new with rails and i am using "devise" gem for authentication purposes. At first i add a new user through default sign up page (E.g./users/sign_up) Then, i made "sign_up" page only available to signed_in users by following instructions from Devise before filter that prevents access to "new_user_registration_path" unless user is signed-in Now, after sign in process when i try open sign up page it always directs me to root_path! How can i access sign up page? My "roots.rb" file as follows: Example::Application.routes.draw do devise_for :users, :controllers => { :registrations => 'registrations'} resources :companies resources :orders resources :customers root :to => "welcome#index" end Thank you all!

  • SharePoint 2010 – Central Admin tooling to create host header site collections

    - by eJugnoo
    Just like SharePoint 2007, you can create host-header based site collections in SharePoint 2010 as well. It means, that you do not necessarily need to create a site-collection under a managed path like /sites/, you can create multiple root-level site collections on same web-application/port by using host-header site collections. All you need to do is point your domain or sub-domain to your web-application and create a matching site-collection that you want. But, just like in 2007, it is something that you do by using STSADM, and is not available on Central Admin UI in 2010 as well. Yeah, though you can now also use PowerShell to create one: C:\PS>$w = Get-SPWebApplication http://sitename   C:\PS>New-SPSite http://www.contoso.com -OwnerAlias "DOMAIN\jdoe" -HostHeaderWebApplication $w -Title "Contoso" -Template "STS#0"   This example creates a host header site collection. Because the template is provided, the root Web of this site collection will be created. .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } I’ve been playing with WCM in SharePoint 2010 more and more, and for that I preferred creating hosts file entries for desired domains and create site-collections by those headers – in my dev environment. I used PowerShell initially, but then got interested to build my own UI on Central Admin instead. Developed with Visual Studio 2010 So I used new Visual Studio 2010 tooling to create an empty SharePoint 2010 project. Added an application page (there is no option to add _Admin page item in VS 2010 RC), that got created in Layouts “mapped” folder. Created a new Admin mapped folder for 14-“hive”, and moved my new page there instead. Yes, I didn’t change the base class for page, its just that it runs under _admin, but it is indeed a LayoutsPageBase inherited page. To introduce a action-link in Central Admin console, I created following element: 1: <Elements xmlns="http://schemas.microsoft.com/sharepoint/"> 2: <CustomAction 3: Id="CreateSiteByHeader" 4: Location="Microsoft.SharePoint.Administration.Applications" 5: Title="Create site collections by host header" 6: GroupId="SiteCollections" 7: Sequence="15" 8: RequiredAdmin="Delegated" 9: Description="Create a new top-level web site, by host header" > 10: <UrlAction Url="/_admin/OfficeToolbox/CreateSiteByHeader.aspx" /> 11: </CustomAction> 12: </Elements> .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Used Reflector to understand any special code behind createpage.aspx, and created a new for our purpose – CreateSiteByHeader.aspx. From there I quickly created a similar code behind, without all the fancy of Farm Config Wizard handling and dealt with alternate implementations of sealed classes! Goal was to create a professional looking and OOB-type experience. I also added Regex validation to ensure user types a valid domain name as header value. Below is the result…   Release @ Codeplex I’ve released to WSP on OfficeToolbox @ Codeplex, and you can download from here. Hope you find it useful… -- Sharad

  • No more admin users?

    - by Kevin
    I am trying to install 12.04 on a Windows 7 machine. I used the Windows installer because I can't get the USB to work. When using the Windows installer it uses the user name on Windows 7. I wanted to change the admin name and set up some standard users. For some reason the admin password would not work and it changed all the users to 'standard.' Now I cannot add any users. Should I just reinstall?

  • Admin form that generates an email confirmation ends up in SPAM [duplicate]

    - by PJD Creative
    This question already has an answer here: How can I prevent my mail from being classified as spam? 10 answers I have an admin form that I have setup for a client, that generates an email confirmation from a template I have designer... It works really well but it ends up in spam some of the time, and this is real frustrating as it is just confirming some details for the customer of what they have just booked, not at all spam, and is accessed via a page where the admin requires login. Any suggestions as to why this may end up in spam. It does have dollar signs ($$) as it is confirming a price, im assuming this is one problem, the rest of it is just general dates and info about the confirmation. Is there any suggestions on how to get this out of spam? thanks in advance

  • How can I create a facebook style message system in Rails 3?

    - by Angela
    I am trying to create a basic message system that allows users to send messages to each other and display it in a simple "Inbox" that shows both messages received and sent, as well as the status of read or unread. Ideally I could reuse existing code. But if not, can someone provide a framework to help me do it? I started to use a single Message record that has UserMessage - one for the sender, one for the receiver. That way I could have separate status. But I'm not sure I'm quite doing it right and would like some guidance. Thanks.

  • Why does tomcat-admin install require adding admin and manager to tomcat-users.xml manually?

    - by J G
    I installed tomcat6 on lucid using apt-get. All working. I installed tomcat-admin. Not working. I amended the /etc/tomcat6/tomcat-users.xml file to uncomment the users and roles (from the default) to be like the following: <role rolename="tomcat"/> <role rolename="role1"/> <user username="tomcat" password="password" roles="tomcat"/> <user username="both" password="password" roles="tomcat,role1"/> <user username="role1" password="password" roles="role1"/> This still didn't work. Then from the following page I added. <role rolename="manager"/> <user username="admin" password="secret" roles="manager"/> then it worked. Why doesn't this occur as part of the install? (Why isn't this in the Ubuntu Manual on Tomcat ?)

  • Is Ruby on Rails' Active Record an example of Aspect-Oriented Programming?

    - by B Seven
    From Clean Code, about Cross-Cutting Concerns: Note that concerns like persistence tend to cut across the natural object boundaries of a domain. You want to persist all your objects using generally the same strategy, for example, using a particular DBMS... Is Active Record an example of aspect-oriented programming? In AOP, modular constructs called aspects specify which points in the system should have their behavior modified in some consistent way to support a particular concern. This specification is done using a succinct declarative or programmatic mechanism. If Active Record is an example of AOP, what is the "aspect"? Is it the class declaration that inherits from Active Record? class Foo < ActiveRecord::Base

  • Ruby on rails not popular in big international IT companies?

    - by maro
    I would like to ask you for advice more experienced ROR developers. I am new in programming and like to idea of ROR and I am before the decision on which programing language to specialize Java vs ROR. In the future I wish to learn for bigger international IT companies (IBM, Accenture etc.) but as I am reading their job openings, most of them are hiring Java, C++, .NET... Is the ROR used only in startups or also in bigger companies as well? What should be the reasons of their preference of Java over ROR?

  • How to do custom display and auto-select in django admin multi-select field?

    - by rsp
    I'm new to django, so please feel free to tell me if I'm doing this incorrectly. I am trying to create a django ordering system. My order model: class Order(models.Model): ordered_by = models.ForeignKey(User, limit_choices_to = {'groups__name': "Managers", 'is_active': 1}) in my admin ANY user can enter an order, but ordered_by must be someone in the group "managers" (this is the behavior I want). Now, if the logged in user happens to be a manager I want it to automatically fill in the field with that logged in user. I have accomplished this by: class OrderAdmin(admin.ModelAdmin): def formfield_for_foreignkey(self, db_field, request, **kwargs): if db_field.name == "ordered_by": if request.user in User.objects.filter(groups__name='Managers', is_active=1): kwargs["initial"] = request.user.id kwargs["empty_label"] = "-------------" return db_field.formfield(**kwargs) return super(OrderAdmin, self).formfield_for_foreignkey(db_field, request, **kwargs) This also works, but the admin puts the username as the display for the select box by default. It would be nice to have the user's real name listed. I was able to do it with this: class UserModelMultipleChoiceField(forms.ModelMultipleChoiceField): def label_from_instance(self, obj): return obj.first_name + " " + obj.last_name class OrderForm(forms.ModelForm): ordered_by = UserModelChoiceField(queryset=User.objects.all().filter(groups__name='Managers', is_active=1)) class OrderAdmin(admin.ModelAdmin): form = OrderForm My problem: I can't to both of these. If I put in the formfield_for_foreignkey function and add form = OrderForm to use my custom "UserModelChoiceField", it puts the nice name display but it won't select the currently logged in user. I'm new to this, but my guess is that when I use UserModelChoiceField it "erases" the info passed in via formfield_for_foreignkey. Do I need to use the super() function somehow to pass on this info? or something completely different?

  • When working with gems in Rails, what does 'cannot remove Object::ClassMethods' stem from?

    Frequently I have run into a problem when installing gems that provides a problem like: Does anyone know what this stems from?

  • Ruby on rails model and controllers inside of different namespaces

    - by Nelson LaQuet
    OK. This is insane. I'm new to RoR and I really want to get into it as everything about it that I have seen so far makes it more appealing to the type of work that I do. However, I can't seem to accomplish a very simple thing with RoR. I want these controlers: /admin/blog/entries (index/show/edit/delete) /admin/blog/categories (index/show/edit/delete) /admin/blog/comments (index/show/edit/delete) ... and so on And these models: Blog::Entry (table: blog_entries) Blog::Category (table: blog_categories) Blog::Comments (table: blog_comments) ... and so on Now, I have already gone though quite a bit of misery to make this work. My first attempt was with generating scaffolding (I'm using 2.2.2). I generated my scaffolding, but had to move my model, then fix the references to the model in my controller (see http://stackoverflow.com/questions/903258/ruby-on-rails-model-inside-namespace-cant-be-found-in-controller). That is already a big of a pain, but hey, I got it to work. Now though form_for won't work and I cannot figure out how to use the url helpers (I have no idea what these are called... they are the automatically generated methods that return URLs to controllers associated with a model). I cannot figure out what their name is. My model is Blog::Entries. I have tried to mess with the route.rb's map's resource method, but no luck. When I attempt to use form_for with my model, I get this error undefined method `blog_entries_path' for #<ActionView::Base:0xb6848080> Now. This is really quite frustrating. I am not going to completely destroy my code's organization in order to use this framework, and if I cannot figure out how to accomplish this simple task (I have been researching this for at least 5 hours) then I simply cannot continue. Are there any ideas on how to accomplish this? Thanks EDIT Here are my routes: admin_blog_entries GET /admin_blog_entries {:controller=>"admin_blog_entries", :action=>"index"} formatted_admin_blog_entries GET /admin_blog_entries.:format {:controller=>"admin_blog_entries", :action=>"index"} POST /admin_blog_entries {:controller=>"admin_blog_entries", :action=>"create"} POST /admin_blog_entries.:format {:controller=>"admin_blog_entries", :action=>"create"} new_admin_blog_entry GET /admin_blog_entries/new {:controller=>"admin_blog_entries", :action=>"new"} formatted_new_admin_blog_entry GET /admin_blog_entries/new.:format {:controller=>"admin_blog_entries", :action=>"new"} edit_admin_blog_entry GET /admin_blog_entries/:id/edit {:controller=>"admin_blog_entries", :action=>"edit"} formatted_edit_admin_blog_entry GET /admin_blog_entries/:id/edit.:format {:controller=>"admin_blog_entries", :action=>"edit"} admin_blog_entry GET /admin_blog_entries/:id {:controller=>"admin_blog_entries", :action=>"show"} formatted_admin_blog_entry GET /admin_blog_entries/:id.:format {:controller=>"admin_blog_entries", :action=>"show"} PUT /admin_blog_entries/:id {:controller=>"admin_blog_entries", :action=>"update"} PUT /admin_blog_entries/:id.:format {:controller=>"admin_blog_entries", :action=>"update"} DELETE /admin_blog_entries/:id {:controller=>"admin_blog_entries", :action=>"destroy"} DELE

I can provide additional info from the out file if necessary. I've read that some people use SQLite for dev and test then MySQL in prod but that sounds like a pretty horrible idea.

  • Rails destroy confirm with Jquery AJAX

    - by Mike
    I have got this working for the most part. My rails link is: <%= link_to(image_tag('/images/bin.png', :alt => 'Remove'), @business, :class => 'delete', :confirm => 'Are you sure?', :id => 'trash') %> :class = "delete" is calling an ajax function so that it is deleted and the page isn't refreshed that works great. But because the page doesn't refresh, it is still there. So my id trash is calling this jquery function: $('[id^=trash]').click(function(){ var row = $(this).closest("tr").get(0); $(row).hide(); return false; }); Which is hiding the row of whatever trash icon i clicked on. This also works great. I thought I had it all worked out and then I hit this problem. When you click on my trash can I have this confirm box pop up to ask you if you are sure. Regardless of whether you choose cancel or accept, the jquery fires and it hides the row. It isn't deleted, only hidden till you refresh the page. I tried changing it so that the prompt is done through jquery, but then rails was deleteing the row regardless of what i choose in my prompt because the .destroy function was being called when the prompt was being called. My question really is how can i get the value to cancel or accept from the rails confirm pop up so that in my jquery I can have an if statement that hides if they click accept and does nothing if they click cancel. EDIT: Answering Question below. That did not work. I tried changing my link to: <%= link_to(image_tag('/images/bin.png', :alt => 'Remove'), @business, :class => "delete", :onclick => "trash") %> and putting this in my jquery function trash(){ if(confirm("Are you sure?")){ var row = $(this).closest("tr").get(0); $(row).hide(); return false; } else { //they clicked no. } } But the function was never called. It just deletes it with no prompt and doesn't hide it. But that gave me an idea. I took the delete function that ajax was calling $('a.delete').click (function(){ $.post(this.href, {_method:'delete'}, null, "script"); $(row).hide(); }); And modified it implementing your code: remove :confirm = 'Are you sure?' $('a.delete').click (function(){ if(confirm("Are you sure?")){ var row = $(this).closest("tr").get(0); $.post(this.href, {_method:'delete'}, null, "script"); $(row).hide(); return false; } else { //they clicked no. return false; } }); Which does the trick.

    - by fenec
    I am implemeting a facebook application in rails using facebooker plugin, therefore it is very important to use this architecture if i want to update multiple DOM in my page. if my code works in a regular rails application it would work in my facebook application. i am trying to use ajax to let the user know that the comment was sent, and update the comments bloc. migration: class CreateComments < ActiveRecord::Migration def self.up create_table :comments do |t| t.string :body t.timestamps end end def self.down drop_table :comments end end controller: class CommentsController < ApplicationController def index @comments=Comment.all end def create @comment=Comment.create(params[:comment]) if request.xhr? @comments=Comment.all render :json=>{:ids_to_update=>[:all_comments,:form_message], :all_comments=>render_to_string(:partial=>"comments" ), :form_message=>"Your comment has been added." } else redirect_to comments_url end end end view: <script> function update_count(str,message_id) { len=str.length; if (len < 200) { $(message_id).innerHTML="<span style='color: green'>"+ (200-len)+" remaining</span>"; } else { $(message_id).innerHTML="<span style='color: red'>"+ "Comment too long.

  • Rails: (Devise) Two different methods for new users?

    - by neezer
    I have a Rails 3 app with authentication setup using Devise with the registerable module enabled. I want to have new users who sign up using our outside register form to use the full Devise registerable module, which is happening now. However, I also want the admin user to be able to create new users directly, bypassing (I think) Devise's registerable module. With registerable disabled, my standard UsersController works as I want it to for the admin user, just like any other Rail scaffold. However, now new users can't register on their own. With registerable enabled, my standard UsersController is never called for the new user action (calling Devise::RegistrationsController instead), and my CRUD actions don't seem to work at all (I get dumped back onto my root page with no new user created and no flash message). Here's the log from the request: Started POST "/users" for 127.0.0.1 at 2010-12-20 11:49:31 -0500 Processing by Devise::RegistrationsController#create as HTML Parameters: {"utf8"=>"?", "authenticity_token"=>"18697r4syNNWHfMTkDCwcDYphjos+68rPFsaYKVjo8Y=", "user"=>{"email"=>"[email protected]", "password"=>"[FILTERED]", "password_confirmation"=>"[FILTERED]", "role"=>"manager"}, "commit"=>"Create User"} SQL (0.9ms) ... User Load (0.6ms) SELECT "users".* FROM "users" WHERE ("users"."id" = 2) LIMIT 1 SQL (0.9ms) ... Redirected to http://test-app.local/ Completed 302 Found in 192ms ... but I am able to register new users through the outside form. How can I get both of these methods to work together, such that my admin user can manually create new users and guest users can register on their own? I have my Users controller setup for standard CRUD: class UsersController < ApplicationController load_and_authorize_resource def index @users = User.where("id NOT IN (?)", current_user.id) # don't display the current user in the users list; go to account management to edit current user details end def new @user = User.new end def create @user = User.new(params[:user]) if @user.save flash[:notice] = "#{ @user.email } created." redirect_to users_path else render :action => 'new' end end def edit end def update params[:user].delete(:password) if params[:user][:password].blank? params[:user].delete(:password_confirmation) if params[:user][:password].blank? and params[:user][:password_confirmation].blank? if @user.update_attributes(params[:user]) flash[:notice] = "Successfully updated User." redirect_to users_path else render :action => 'edit' end end def delete end def destroy redirect_to users_path and return if params[:cancel] if @user.destroy flash[:notice] = "#{ @user.email } deleted." redirect_to users_path end end end And my routes setup as follows: TestApp::Application.routes.draw do devise_for :users devise_scope :user do get "/login", :to => "devise/sessions#new", :as => :new_user_session get "/logout", :to => "devise/sessions#destroy", :as => :destroy_user_session end resources :users do get :delete, :on => :member end authenticate :user do root :to => "application#index" end root :to => "devise/session#new" end
