I'm stuck on something that doesn't make sense! I'm simply trying to submit a form with "comments" on a blog post.
Here is my form view:
<%= form_for #comment, :remote => true, :url => forumpost_comments_path(forumpost) do |s| %>
<div class="field">
<%= s.label :content, "Write a comment" %>
<%= s.text_area :content, :rows => "3" %>
</div>
<%= s.submit "Reply"%>
<% end %>
Here is my controller:
def create
#forumpost = Forumpost.find_by_id(params[:forumpost_id])
#comment = #forumpost.comments.build(params[:comment])
#comment.user_id = current_user.id
if #comment.save
redirect_to search_static_pages_path
else
redirect_to search_static_pages_path
end
end
Here is my model:
class Comment < ActiveRecord::Base
attr_accessible :content
belongs_to :user
belongs_to :forumpost
validates :user_id, presence: true
validates :forumpost_id, presence: true
end
And here are my logs:

As you can see, the content portion is nil even though I have filled out the content field and submitted it.
I would really appreciate any guidance on the matter! Thanks!

I've followed Railscast episode #262 tutorial on ancestry. But when I submit my form, the rails server log says that parent_id is empty:

I guess somethings wrong with my create method in the CommentsController, but I can't figure out what's missing. So, I got this working. I was submitting the form from my posts/show view, so I had to call #comment = Comment.new(:parent_id => params[:parent_id]) in the show action of the post-controller as well.
If you are using Rails >3.0.0 try this in your comments controller:
#comment = Comment.new
#comment.parent_id=params[:parent_id]
instead of
#comment = Comment.new(:parent_id => params[:parent_id])
Add :parent_id to comment_params in the comments controller.
Currently implementing Threaded Messaging. via RailsCast
I've installed the Ancestry gem, however all messages that I create are parents. ie.) Ancestry = nil
Even after passing my parent:id to new action
Message Controller
def index
#message = Message.new
#user = current_user
#sent_messages = current_user.sent_messages
#received_messages = current_user.received_messages
end
def new
#message = Message.new
#message.parent_id = params[:parent_id]
end
Index.html
<% for incoming in #received_messages %>
<%= render partial: "message", locals: {incoming: incoming} %>
_message.html.erb
</div>
<%= link_to "Reply", new_message_path(:parent_id => incoming) ,class: "regular" %>
</div>
new.html.erb
<%= form_for #message do |f| %>
<p>
To:<br />
<%= f.hidden_field :parent_id %>
<%= f.hidden_field :recipient, :value => (#message.parent.sender.name) %>
</p>
<p>

<%= submit_tag "Send Threaded Reply" %>
</p>
<% end %>
Message.rb
class Message < ActiveRecord::Base
attr_accessible :recipient, :subject, :body, :parent_id

end
My console after creating a message:

After Bigxiang's comment, I decided to take a look at my create function.
I have been passing my params individually, So using
#message.parent_id = params[:message][:parent_id] worked for me
Cheers
My problem is that a tag wont be created which is nested in posts.
I have Post which have tags nested in them. Like this
resources :posts do
resources :tags, :only => [:new, :create, :destroy]
end
In my tags controller i have this
class TagsController < ApplicationController
before_filter :authenticate_user!
def new
#post = Post.find(params[:post_id])
#tag = Tag.new
end
def create
#post = Post.find(params[:post_id])
#tag = #post.tags.build(params[:tags])
if #tag.save
flash[:notice] = "Tag created"
redirect_to #tag.post
else
flash[:error] = "Could not add tag at this time"
redirect_to #tag.post
end
end
end
new.html.erb
<%= form_for [#post, #tag] do |f| %>
<% if #tag.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#tag.errors.count, "error") %> prohibited this tag from being saved:</h2>
<ul>
<% #tag.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.text_field :tagable_type, :placeholder => "Type" %>
</div>
<div class="field">
<%= f.text_field :tagable_id, :placeholder => "Id" %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
Tag model
class Tag < ActiveRecord::Base
attr_accessible :post_id, :user_id, :tagable_type, :tagable_id
validates :post_id, presence: true
belongs_to :tagable, :polymorphic => true
belongs_to :post
belongs_to :user
end
Post model
class Post < ActiveRecord::Base

has_many :comments, :as => :commentable, :dependent => :destroy

end
UPDATE:
Now i can create a tag but the tagable_type and tagable_id fields are not being created for some reaseon

There is a typo in the create() action of your TagsController:
#tag = #post.tags.build(params[:tags])
The hash used to create the tag should be params[:tag], not params[:tags].
So I have a deeply nested association among Polls, Questions, and Answers:
class Poll < ActiveRecord::Base
attr_accessible :description, :end_time, :start_time, :title, :user_id, :questions_attributes, :is_live
belongs_to :user
has_many :questions, :dependent => :destroy
# This is the plularized form of sms, it's not smss
has_many :sms, :through => :questions
has_many :feedbacks
accepts_nested_attributes_for :questions, :reject_if => lambda { |a| a[:content].blank?}, :allow_destroy => true
end
class Question < ActiveRecord::Base
attr_accessible :poll_id, :title, :answer_attributes
belongs_to :poll
has_many :answers, :dependent => :destroy
# THis is the plularized form of sms, it's not smss
has_many :sms
#If someone creates a form with a blank question field at the end, this will prevent it from being rendered on teh show page
accepts_nested_attributes_for :answers, :reject_if => lambda { |a| a[:content].blank?}, :allow_destroy => true
end
class Answer < ActiveRecord::Base
attr_accessible :is_correct, :question_id, :title
belongs_to :question
end
And am trying to save all objects in a single fields_for form like so.
= form_for #poll, :class=>'create-poll-form' do |f|
= f.text_field :title, :autofocus => true, :placeholder => "Poll Title"
= f.text_field :description, :placeholder => 'Description'
= f.fields_for :questions do |builder|
= render "questions/question_fields", :f => builder
= f.submit "Create Poll", :class => 'btn btn-danger'
Questions Partials
%p
= f.label :title, "Question"
= f.text_field :title
= f.check_box :_destroy
= f.label :_destroy, "Remove Question"
%p
= f.fields_for :answers do |builder|
= render "answers/answer_fields", :f => builder
Answers Partial
%p
= f.label :title, "Answer"
= f.text_field :title
= f.check_box :_destroy
= f.label :_destroy, "Remove Answer"
Yet the PollsController isn't persisting the data:
def create
binding.pry
#poll = current_user.polls.new(params[:poll])
# #poll = Poll.create(params[:poll])
binding.pry
#poll.save!
redirect_to root_path
end
def new
#poll = Poll.new
1.times do
question = #poll.questions.build
2.times {question.answers.build}
end
end
Any tips here would be amazing, I've been working on this for a bit and it's stumping me! Thanks in advance!

I'm not sure if this is the problem but in your
class Question < ActiveRecord::Base
attr_accessible :poll_id, :title, :answer_attributes
but in your log file it has
Parameters: {"utf8"=>"✓", "authenticity_token"=>"hk+KuNsTLx3sH9pE7Mf8XETGsmxTsRN4/tWUBn3CIVE=", "poll"=>{"title"=>"Testing 1-2-1-2", "description"=>"Up on the mic", "questions_attributes"=>{"0"=>{"title"=>"Cake or Death?", "_destroy"=>"0", "answers_attributes"=>{"0"=>{"title"=>"Cake", "_destroy"=>"0"}, "1"=>{"title"=>"Death", "_destroy"=>"0"}}}}}, "commit"=>"Create Poll"}
The difference being :answers_attributes, rather than :answer_attributes i.e. answer vs answer*s
This may be causing the data to be thrown away.
Noob question, I'm sure, but I can't seem to find my mistake. SymptomSets are saving w/ the proper user_id, but the nested symptoms disappear. Note that the user model structure is identical to that in the Rails Tutorial (save that it has_many :symptom_sets)
Models:
class SymptomSet < ActiveRecord::Base
attr_accessible :symptoms, :symptoms_attributes
belongs_to :user
has_many :symptoms, :dependent => :destroy
accepts_nested_attributes_for :symptoms, allow_destroy: true
end
class Symptom < ActiveRecord::Base
attr_accessible :name, :duration, :symptom_set_id
belongs_to :symptom_set
end
Controller:
class SymptomSetsController < ApplicationController
before_filter :signed_in_user, only: [:create, :new]
def new
#symptom_set = SymptomSet.new
3.times do
symptom = #symptom_set.symptoms.build
end
end
def create
#symptom_set = current_user.symptom_sets.build(params[:symptom_sets])
if #symptom_set.save
flash[:success] = "Symptoms submitted!"
redirect_to root_url
else
render 'static_pages/home'
end
end
And the View:
<%= simple_form_for #symptom_set, :html => { :class => 'form-inline' } do |f| %>
<%= f.fields_for :symptoms do |builder| %>
<%= render 'symptom_fields', f: builder %>
<% end %>
<div class="actions"><%= f.submit %></div>
<% end %>
And the partial:
<%= f.input :name,
:collection=> ["Cough", "Fever", "Headache", "Lethargy"],
label: "Symptom",
prompt: "Select a symptom",
:input_html => { :class => "span3" }%>
<%= f.input :duration,
:collection => 1..14,
label: "Duration",
prompt: "How many days?" %>
finally, the rails server console outputs the following:

I'd try changing:
#symptom_set = current_user.symptom_sets.build(params[:symptom_sets])
to:
#symptom_set = current_user.symptom_sets.new(params[:symptom_sets])
I don't know if build would work there.
And also checking the params on the terminal log if it is called symptom_sets and if it's sending the parameters of nested form attributes.
EDIT:
I Really think your param's name would be symptom_set in singular. check that.
