  • How do I pass object values with render :action => 'new'

    - by PlanetMaster
    Hi, In an app I have the following: def new @property = Property.new(:country_id => 1, :user_id => current_user.id, :status_id => 'draft') end def create @property = Property.new(params[:property]) if @property.save flash[:success] = t('The_property_is_successfully_created') redirect_to myimmonatie_url else flash.now[:error]=t("The_property_could_not_be_created") render :action => 'new' end end When an error accors, the line render :action = 'new' gets executed, but the my form gives an error: user blank country blank These cannot be blank (defined in model), meaning this code: @property = Property.new(:country_id => 1, :user_id => current_user.id, :status_id => 'draft') is not executed anymore. What is the reason and solution? Thanks!

  • Transfer values from one selection box to another

    - by Tonya Cash
    I need to populate the first box with the items from a db table. Users would choose from the first box, and either drag value(items) to the second for selection, or would select items, and then click a button to move them over to the 2nd box. After that I need to update the db with the selected values/items.

  • How do i create multiple URLs with /controller/action/ format?

    - by Angela
    I have several controller/actions where no :id needs to be passed. what I did with the first two was make a custom route defining the controller and action. I thought that the default would allow me to create controller/action.xml by using respond_to in the controller, but that doesn't appear to be the right way. How can I create controller/action URL's (some are .xml) without creating a special route with map.connect?

  • Skipping authorization for certain methods

    - by mathee
    Per the Agile Development book, I have an Admin MVC that controls how users log in. In ApplicationController, I have a before_filter that checks for authorization. So, this will check that the user has logged in for every page. The problem is that I want everyone to be able to access the new method, for example, in Users (that is, anyone should be able to create a new user -- naturally! Only admin users should have access to the other methods in UsersController such as edit, etc.). What's the best way to do that?

  • has_many :through default values

    - by David Lyod
    I have a need to design a system to track users memberships to groups with varying roles (currently three). class Group < ActiveRecord::Base has_many :memberships has_many :users, :through => :memberships end class Role < ActiveRecord::Base has_many :memberships has_many :users, :through => :memberships end class Membership < ActiveRecord::Base belongs_to :user belongs_to :role belongs_to :group end class User < ActiveRecord::Base has_many :memberships has_many :groups, :through => :memberships end Ideally what I want is to simply set @group.users << @user and have the membership have the correct role. I can use :conditions to select data that has been manually inserted as such : :conditions => ["memberships.grouprole_id= ? ", Grouprole.find_by_name('user')] But when creating the membership to the group the grouprole_id is not being set. Is there a way to do this as at present I have a somewhat repetitive piece of code for each user role in my Group model.

  • How to customize the to_json method in rails3?

    - by lashleigh
    I want to convert an array of Place objects to json, I've been doing it like this: var places = <%= @places.to_json.html_safe %>; The only problem is that every place in the @places array has an associated tag list that doesn't get included. I'm using the acts_as_taggable_on gem to handle tags, so to get the tag list for a place I need to say place.tag_list. What do I have to do to get the tag_list included for each place in the javascript array? I think I'll need to write my own to_json method but I don't know how. Thanks

  • Is this the correct way to set up has many with multiple associations?

    - by user323763
    I'm trying to set up a new project for a music site. I'm learning ROR and am a bit confused about how to make join models/tables. Does this look right? I have users, playlists, songs, and comments. Users can have multiple playlists. Users can have multiple comments on their profile. Playlists can have multiple songs. Playlists can have comments. Songs can have comments. class CreateTables < ActiveRecord::Migration def self.up create_table :users do |t| t.string :login t.string :email t.string :firstname t.string :lastname t.timestamps end create_table :playlists do |t| t.string :title t.text :description t.timestamps end create_table :songs do |t| t.string :title t.string :artist t.string :album t.integer :duration t.string :image t.string :source t.timestamps end create_table :comments do |t| t.string :title t.text :body t.timestamps end create_table :users_playlists do |t| t.integer :user_id t.integer :playlist_id t.timestamps end create_table :playlists_songs do |t| t.integer :playlist_id t.integer :song_id t.integer :position t.timestamps end create_table :users_comments do |t| t.integer :user_id t.integer :comment_id t.timestamps end create_table :playlists_comments do |t| t.integer :playlist_id t.integer :comment_id t.timestamps end create_table :songs_comments do |t| t.integer :song_id t.integer :comment_id t.timestamps end end def self.down drop_table :playlists drop_table :comments drop_table :songs_comments drop_table :users_comments drop_table :users_playlists drop_table :users drop_table :playlists drop_table :songs drop_table :playlists end end

  • How do you pass self to class_eval in ruby?

    - by klochner
    I'm working on a metaprogramming task, where I'm trying to use a single method to define a polymorphic association in the calling class, while also defining the association in the target class. I need to pass in the name of the calling class to get the association right. Here's a snippet that should get the idea across: class SomeClass < ActiveRecord::Base has_many :join_models, :dependent=:destroy end class JoinModel < ActiveRecord::Base belongs_to :some_class belongs_to :entity, :polymorphic=true end module Foo module ClassMethods def acts_as_entity has_many :join_models, :as=:entity, :dependent=:destroy has_many :some_classes, :through=:join_models klass = self.name.tableize SomeClass.class_eval "has_many :#{klass}, :through=:join_models" end end end I'd like to eliminate the klass= line, but don't know how else to pass a reference to self from the calling class into class_eval. any suggestions?

  • link_to syntax with rails3 (link_to_remote) and basic javascript not working in a rails3 app?

    - by z3cko
    i am wondering if the basic link_to syntax is completely broken in current rails3 master or if i am doing some wrong syntax here. = link_to "name", nil, :onlick => "alert('Hello world!');" should actually produce an alert on click. very simple. does not work on my rails3 project! (also no error output!) any ideas? for the general link_to syntax i could not find an example where i could combine a link_to_remote with a confirmation, remote and html class (see my try below) = link_to "delete", {:action => "destroy", :remote => true, :method => :delete, :confirm => "#{a.title} wirklich L&ouml;schen?" }, :class => "trash" even the rails3 api does not help me here: http://rails3api.s3.amazonaws.com/index.html help!

  • exactly what does rake db:migrate do?

    - by happythenewsad
    Does rake db:migrate only add new migrations, or does it drop all migrations/changes and build everything new? I think rake is throwing an error because it is trying to access a table attribute in migration 040 that was deleted in migration 042. somehow my DB and rake are out of synch and I want to fix them. for you experts out there - is it common for rake to get out of synch with migrations? how can I avoid this (no, I do not hand-edit my schema or rake files).

  • Scope of Constants in Ruby Modules

    - by user204078
    I'm having a little problem with constant scope in mixin modules. Let's say I have something like this module Auth USER_KEY = "user" unless defined? USER_KEY def authorize user_id = session[USER_KEY] def end The USER_KEY constant should default to "user" unless it's already defined. Now I might mix this into a couple of places, but in one of those places the USER_KEY needs to be different, so we might have something like this class ApplicationController < ActionController::Base USER_KEY = "my_user" include Auth def test_auth authorize end end I would expect that USER_KEY would be "my_user" when used in authorize, since it's already defined, but it's still "user", taken from the modules definition of USER_KEY. Anyone have any idea how to get authorize to use the classes version of USER_KEY?

  • How to turn off SSL on heroku

    - by rockyroadster555
    I'm redirecting a domain to Heroku using a cname. Currently Its working but is giving me an ssl error. Is there a way to turn off ssl on heroku? Heres the SSL Error This is probably not the site you are looking for! You attempted to reach app.grewpr.com, but instead you actually reached a server i identifying itself as *.herokuapp.com. This may be caused by a misconfiguration on the server or by something more serious. An attacker on your network could be trying to get you to visit a fake (and potentially harmful) version of app.grewpr.com. You should not proceed, especially if you have never seen this warning before for this site. When I try to go to http://pure-chamber-1979.herokuapp.com/ it automatically redirects me to the ssl version. Is there a way to turn this off?
