Using this.store.filter with the ID of the belongs_to model
Ember Data works with all its IDs as strings. Changing your check to === '1' should get this going for you. import Ember from 'ember'; export default Ember.Route.extend({ model: function() { return Ember.RSVP.hash({ layouts: this.store.filter('layout', { account_id: 1 }, function(layout) { console.log(layout.get('account').content.id); return layout.get('account').content.id === '1'; }) }); } });...
Custom foreign_key in model gives PG::Error column does not exist - Rails
ruby-on-rails,postgresql,foreign-keys,belongs-to
I don't really use has_many and belongs_to with different foreign keys than the standard, but according to the docs I would do this: class VideoCollection < Collection has_many :video_works, foreign_key: "folder_id" end class VideoWork < Work belongs_to :folder, class_name: "VideoCollection", foreign_key: "folder_id" end Your Pg error says that the association...

Rails select_tag will not access belongs_to relation
ruby-on-rails,ruby,model,html-select,belongs-to
Either you add a method to your employee that you can call, like: class Employee < ActiveRecord::Base ... def entity_name self.entity.name end end and then: select_tag "employee_compensation_benefits_selection", options_from_collection_for_select(@employees, "id", "entity_name", "1") or you can use a lambda instead of adding a method: select_tag "employee_compensation_benefits_selection", options_from_collection_for_select(@employees, "id", lambda { |employee| employee.entity.name...
Input new record into database using a form with the association belongs_to
ruby-on-rails,controller,associations,belongs-to,button-to
You are on the right track, you have created an association, now you just need to reference the project in the create method like this : def new @project = Project.find params[:project_id] @issue = @project.issues.build end def create @project = Project.find(params[:project_id]) @issue = @project.issues.build(issue_params) ## rest of code end then...
Understanding Rails Model Associations
ruby-on-rails,rails-activerecord,belongs-to,has-one
Rails Guides provides an explanation as to why you're experiencing the problem. Essentially, when you declare a belongs_to relationship, the foreign key appears on the table for the class declaring it. When you declare a has_one relationship, the foreign key is on the table for the class in the declaration....
Laravel belongsTo throwing undefined function App/BelongsTo() exception
php,sql,laravel,eloquent,belongs-to
Well, this error occurred because I had '.' in place of '->'. I couldn't figure out why it was always throwing the exact same error regardless if I did $this.belongsTo('App\User'); or $this.hasMany('App\User'); or even $this.thecakeisalie('App\User'); until I sat staring at the text between my many models yet again. Then, lo...
Ruby on Rails: Child Class Gives Parent Class values when child class is created
ruby-on-rails,ruby,parent-child,belongs-to
I discovered the answer to this a few days ago, but forgot to wrap this up. I was thinking about the whole architecture of this wrong. Upon talking to the senior devs around my office we came to the conclusion that in most standard cases, you will want to create...
optional belongs_to for renamed active_admin resources
ruby-on-rails,ruby,activeadmin,belongs-to
ActiveAdmin allows you to use nested resources with a belongs_to method, as you clearly already know: ActiveAdmin.register Project do end ActiveAdmin.register Ticket do belongs_to :project end ActiveAdmin.register Milestone do belongs_to :project end Because Inherited Resources' firepower can't be aware of every custom implementation in the book, you may have to...
belong_to not working ruby and rails
If you want to get the user who has the micropost, you should use micropost.user. For example: @microposts.first.user will return the user of @microposts's first record.
one model belongs to two models
ruby-on-rails,ruby,activerecord,belongs-to
The Reception model definitely doesn't belong_to the Attendee model. The relationship between Receptions and Attendees will be either a has_many, or a 'has_many through' relationship. It's worth reading through the full doco on assocations. You mention: The idea is that a user will be able to go to the wedding's...

How should I set up a Rails app so that some Objects are linked to others (belong_to) but not all Objects have this relationship?
ruby-on-rails,associations,has-many,belongs-to
If I am reading this right, then all you need to do is add another has_many :key_contacts relation to your SalesOpportunity model (and belongs_to :sales_opportunity in your KeyContacts model). Then relate all contacts belonging to a specific sales opportunity.

Rails belongs_to returning nil
ruby-on-rails,json,belongs-to,rails-api
I am pretty sure your problem is, that the database field for the foreign key and the associated model are having the same name. The database field is made available as a member method called 'tourn' in the model by ActiveRecord and this obviously collides with your belongs_to definition which...
Creating relationship between 2 tables in CakePHP using models to write less code
php,cakephp,model,has-many,belongs-to
The problem is that you are fetching only id field in: $cs=$this->CkMmUsersKta->find("all",array('fields'=>array('CkMmUsersKta.id'))); You should specify the name field also. $cs=$this->CkMmUsersKta->find("all",array('fields'=>array('CkMmUsersKta.id','CkSetupUser.user_name')));...
CakePHP3 - Parent BelongsTo - Database Error PDOException

Grails belongsTo multiple classes
Well this is very much doable, its just that your approach is wrong here. belongsTo is used in a way when an entity must and must be mapped with some other entity. There is nothing like either of them. What you can do is 1. create an Abstract Domain `Book`...
belongs_to with foreign_key not working in one direction
ruby-on-rails,foreign-keys,belongs-to
The SQL generated is using products.id instead of products.symbol because you didn't tell it that the association should use symbol as the primary key instead of the default of id. So, in your Position class just add primary_key: :symbol to the belongs_to and I think that'll do it.
Ruby on Rails If a user has already added data for one product stop them from doing so again relationship
ruby-on-rails,ruby,relationship,models,belongs-to
I would do a model relation like this: user.rb has_many :reviews product.rb has_many :reviews reviews.rb belongs_to :user belongs_to :product # This does the magic for the multiple validation validates_uniqueness_of :user_id, :scope => :product_id, :message=>"You can't review a product more than once", on: 'create' As you can see, i will let...
Laravel / Eloquent - custom relation method
laravel,eloquent,relation,belongs-to
The idea here is to write a function which would check if a relationship is loaded and return that relationship, otherwise it will return the belongsToMany. This would go in your Report class. This is also for Laravel 5. If you have 4, just remove the namespaces from the model...

You might want to use find('threaded'). You can also look into the tree behavior.
Rails 4 Override belongs_to setter
ruby-on-rails,override,setter,belongs-to
This would be better written as a callback. You can use a before_save callback to check for a parent_task and if it is set, clear groups_belonging_to: class Task < ActiveRecord::Base belongs_to :parent_task, class_name: 'Task', foreign_key: 'parent_task_id' before_save :clear_groups if: :parent_task def clear_groups self.groups_belonging_to = [] end end ...
laravel two identical belongsTo() relations, one returns an array another string
mysql,database,laravel,relational-database,belongs-to
You can't name the relationship the same as the name of your foreign key column! Changing either one should work, however I suggest you change the foreign key columns to author_id. Then you also don't need to specify the foreign key column in your relation since you're using the conventional...
rails multiple belogs_to assignments with nested attributes
ruby-on-rails,nested-attributes,belongs-to
As I wrote in the comments, there's two ways of doing this. The first way is to add a hidden field in your subform to set the current user: = simple_nested_form_for(@issue) do |f| = f.input :title = f.fields_for(:comments) do |cf| = cf.input(:content) = cf.hidden(:user, current_user) = f.submit If you do...
ActionView::Template::Error (undefined method `city' for nil:NilClass):
ruby-on-rails,ruby,associations,has-many,belongs-to
You are getting undefined method 'city' for nil:NilClass in below code: <% @sportists.each do |s| %> <%= s.name %> <%= s.surname %> <%= s.trainer.city %> <% end %> which means that there is a sportists record which doesn't have trainer associated to it. So, for that particular sportlist record s.trainer...
Issue with belongs_to and user (devise)
ruby-on-rails,devise,user,belongs-to
It will stay null because you are not using it in the timesheetsController, your create action should be like this : def create @timesheet = current_user.timesheets.build(timesheet_params) redirect_to new_timesheet_path end You have to use that build method to reference the current_user, so the timesheet will have the current_user in the user_id...
Rails JSON Rest API: Getting Child Class from Parent via API Call

You are creating an intermediate table when you're using the OneToMany relationship. You only have to do so when creating a ManyToMany relationship.

Rails 4 - setting belongs_to relationship not working
ruby-on-rails,ruby,stripe-payments,belongs-to
Try adding the inverse relationships: #Plan has_many :teams, inverse_of: :plan #Team belongs_to :plan, inverse_of: teams The inverse relationships help ensure that save works when you save subobjects. Try looking at the id of each item before and after save: p "team_plan.id:#{team_plan.id}, team.plan.id: #{team.plan.id}" team.plan = team_plan p "team_plan.id:#{team_plan.id}, team.plan.id:#{team.plan.id}" team.save!...
