I am trying to make a form and submit a skill and description into a database. I am almost done however I am getting this error after submitting my info:
NameError in SkillsController#create
uninitialized constant Skill::Description
and it points to this action in my controller:
def create
#skills = Skill.new(skill_params)
if #skills.save
redirect_to :action => 'index'
else
#skills = Skill.find(:all)
render :action => 'new'
end
end
I have a private method at the bottom defining params which states:
private
def skill_params
params.require(:skill).permit(:description)
end
I hope this is enough info to find the issue and I will post my form and skill.rb if anyone thinks that will help. Thanks stackers and good luck! I will keep looking into the error and really appreciate any help on the matter.

and this is my schema:
create_table "skills", force: true do |t|
t.datetime "created_at"
end
I am guessing I need to do "rails generate" and I will look into doing that next to add description into the schema. Thanks everyone again, I know I am close to solving this.
I ran "rails generate migration AddDescriptionToSkills description:string" and "rake db:migrate" and I got the schema.rb updated:
create_table "skills", force: true do |t|
t.datetime "created_at"
t.string "description"
end
but I am still getting the same error. Once again thanks everyone and I will keep you updated.

I resolved using ruby 2.1.2.
Thanks to all!
It's actually a bug with rails, the fix is to update Rails as you can see in this commit
https://github.com/rails/rails/commit/e88da370f190cabd1e9750c5b3531735950ab415
I just started rails, every things was working fine and suddenly I got below error.
undefined method `title' for #< Comment:0xbe9aba0>
I tried other posts and did not figure out what is wrong.
Extracted source (around line #6):
#article = Article.find(params[:article_id])//line 4
#comment = #article.comments.new(comment_params)//line 5
**#comment.save** //line 6
redirect_to article_path(#article) //line 7
end

Comment class:

def create
#article = Article.find(params[:article_id])
#comment = #article.comments.new(comment_params)
#comment.save
redirect_to article_path(#article)
end
private
def comment_params
params.require(:comment).permit(:name, :msg, :article_id)
end
end
Article class
class ArticlesController < ApplicationController
def index
#articles = Article.all
end
def show
#article = Article.find(params[:id])
end
end
Let me know if you guys need more details
class Comment < ActiveRecord::Base
belongs_to :article
validates :title, presence: true, length: {minimum: 5}
end
One of the following:
you have a show or index view with a call to name i.e comment.title
you have a validation on name in your comments model
but hard to tell from the info you have given. where do you get the error?
I suspect Comment doesn't have a column called title. Try this to check:
$ rails console
> Comment.column_names
and see if the array includes "title"
The main problem is with your Comment Model. Line number 3 validates :title, presence: true, length: {minimum: 5} Your are not having title column in your comment table.
As you below method, Clearly stated that you don't have title column in your Comment model.
def comment_params
params.require(:comment).permit(:name, :msg, :article_id)
end
So remove validates :title, presence: true, length: {minimum: 5} from your Comment model and all would be good.
I have an undefined method error 'apply_finder_options'
_question.html.erb and where the error says it is
def self.unsolved(params)
where(solved: false).paginate(page: params[:page], order: 'created_at DESC', per_page: 3)
end
def self.search(params)
Questions Controller
def show
puts params
#question = Question.find(params[:id])
#answer = Answer.new

Try changing your unsolved method to like this
def self.unsolved(params)
order('created_at DESC').where(solved: false).paginate(page: params[:page],per_page: 3)
end

As explained at http://guides.rubyonrails.org/form_helpers.html#uploading-files there is no need to set form's encoding to "multipart/form-data" when using form_for (as opposed to using form_tag).
What can it be then? I fear that I'm experiencing some incompatibilities issues between ruby and rails version? Any quick fix? Thanks.
You cannot assign a file object to a binary column and save it. If you really want to just save the file's contents to the database, call read on it before assigning it to your model. You probably want to do something more suited for file uploads, though. Take a look at CarrierWave and Paperclip
