It took me a while to figure out that MEAP code examples like Factory(:user... are deprecated.

In looking at working code in my blogee I found 3 different ways FactoryGirl is used:

1. post_1 = FactoryGirl.create(:post, ...)
2. let!(:post) {create(:post, published:true)}
3. @post = FactoryGirl.create(:post)

What are the distinctions between these 3 statements?

I haven't found a link that displays this.

running the editing comments rspec, I am getting

1. Editing comments with invalid attributes
   Failure/Error: click_link "Edit Comment"
   Capybara::ElementNotFound:
   Unable to find link "Edit Comment"

   ./spec/editing_comments_spec.rb:11:in `block (2 levels) in <top (required)>'

2. Editing comments with valid attributes
   Failure/Error: click_link "Edit Comment"
   Capybara::ElementNotFound:
   Unable to find link "Edit Comment"

   ./spec/editing_comments_spec.rb:11:in `block (2 levels) in <top (required)>'

So the rspec has this in it:

visit posts_path
click_link post.title
click_link comment.author
click_link "Edit Comment"

but on the rendered web page after clicking a post title link I see:
/start of web page

my second post
Edit Post Delete Post Example comment

By: Dave

22 Apr 13:20

my second post content

Add Comment

/end of web page

First, I don't see how the 'click_link comment.author' in the rspec is passing, as there is no such link on the page.

Second, there is no Edit Comment on the page.

So what am I missing here?

It seems that the /comments/show..html.erb is not getting rendered?

When I type
'gem install bundler'

I get this:
'ceeblet [ ~ ]$ gem install bundler
ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory.
'
I've done some searching on the net about this error.

Even though I have rbenv installed it looks like the system installation of ruby is always used. I've put shims in the beginning of my path, and I tried to use

rbenv global 2.0.0p247

thinking that would force the use of the shims version but i guess since they are both the same version it isn't working. I've set my path so that shims comes first. I don't know how to force the use of the shims version.

I thought about explicitly setting a GEMS_HOME variable but then thought that might not be good if I am still using the system version of ruby.

Any help would be appreciated.
Thanks.

Here are a few more things for informational purposes:

In order to use Nitrous desktop, I had to copy my website directory from root to /workspace.
From my new /workspace/lpl directory, will git commit work properly?
Will git push to my project on github work properly?

I realized that I had generated my comment model without the reference to post, and was trying to correct that issue. I rolled back the previous migration and applied the change (or so I thought), but I am getting an error when I db:migrate.
The error follows:
== 20140424001456 AddPostRefToComments: migrating =============================
-- add_reference(:comments, :post, {:index=>true})
rake aborted!
StandardError: An error has occurred, this and all later migrations canceled:

PG::DuplicateColumn: ERROR: column "post_id" of relation "comments" already exists

`async_exec'

At this point, I've tried quite a few things and likely have the db in a fairly crazy state. I committed my change and pushed up to my repository as "messed up the db". Can you take a peek and let me know how to proceed to correct my issue?

Thanks!

I was thinking that this might help anyone not yet familiar with using the command line:
The Command Line Crash Course

1)I can't close or save open files in my nitrous ide for the last 2 days.
I click on the x by the file name in the tab, or the star, and nothing happens.
I have restarted my nitrous virtual machine it has not resolved the problem.

What do I need to do to resolve this problem?

2)Are the email ID's of the students in the class posted somewhere in this github?

Version control is a good skill to have for any software development. The tools we use now are more powerful then the days of cvs and visual source safe. Of course, with power come new concepts and added complexity. And I would argue git is probably the most complex and powerful of the new version control system. This book helps. I got what I needed by scanning it, and it makes for a nice reference when unexpected situations arise.

http://git-scm.com/book

But more importantly, over time you will develop habits of dealing with the various situations that arise. Practice makes perfect.

  def test_changing_hashes
    hash = { :one => "uno", :two => "dos" }
    hash[:one] = "eins"

    expected = { :one => __, :two => "dos" } #line 39
    assert_equal __, hash #line 40

    # Bonus Question: Why was "expected" broken out into a variable
    # rather than used as a literal?
  end

I'm assuming that we need to fill in both blanks for this to pass.

• Based on what I see in this method, the value of :one is changed from "uno" to "eins"
• The blank in line 39 should be filled in with "eins" which would require the blank in line 40 to equal { :one => "eins", :two => "dos" }. Is this right? If so, why doesn't the test pass?

I got this error in creating posts spec and found similar but slightly different code in the book (pictured above). Without solving this issue I passed to the next scenario.

Now I have a similar error in viewing posts spec and anticipate I will do this at least twice more so I thought I'd submit an issue and get some feedback please.

When running the spec for viewing comments, I'm running into a "NoMethodError - undefined method `post=' ". If I understand correctly, the "post=" is supposed to indicate this is a comment nested to the parent post, right? I'm stuck getting this factory to work.

Also getting this same error on the editing comments spec that was provided.

This is the start of the factory for the viewing comments spec I wrote:

feature "Viewing comments" do
  before do
    # setup everything you need - in this case, probably a good idea to set up
    # two Posts, each with 1 Comment
    post_1 = FactoryGirl.create(:post, title: "This is a post", content: "This is the content of my post", author: "Karl")
    FactoryGirl.create(:comment, post: post_1, content: "Looks like a good time.", author: "James Bond")

end

and here is the error in detail:

Regarding 'do |t|', what is the value of t in this class?
Is it the last value processed, i.e. the symbol :purchases?
Or what?

Or just use an issue.

I have wasted many hours on this....

Hopefully Jim/Ben you still have access to my Nitrous.

My app is workspace/lpl

My main model is Plates which can have many Translations.

If you goto the home page it will list all the plates in the DB ok.

Click 'New plate' upper left will take you to a form to input a new plate.

At the bottom of the form is a translation text area.

If you fill in all the form fields (except the plate image one) and click Save, currently you will get this error:

ActiveRecord::UnknownAttributeError in PlatesController#create
unknown attribute: translation
Extracted source (around line #24):

 if plate_params[:meaning] then vote = 1 else vote = 0 end
22 puts plate_params
23 @plate = Plate.new(plate_params.merge(user_id: 1, rated_count: 1, rating: 
24 :input_rating, translation_votes: vote, translations_attributes: [ { plate_id: :id, user_id: 1,
25 votes: 1 }]))
26 # @plate = Plate.new(plate_params.merge(user_id: 1, rated_count: 1, rating: 27 :input_rating, #translation_votes: vote, translations_attributes: [ { plate_id: :id }, { user_id: 1 },
# { meaning: :meaning }, { votes: 1 }]))

Parameters:

 "plate"=>{"plate_number"=>"TCB 7",
 "state"=>"OH",
 "input_rating"=>"1",
 "translation"=>{"meaning"=>"Initials"}},
 "save"=>"Save"}

This is just the latest error of a long string of errors which I have resolved or bypassed.

The fundamental problem is I cannot get the 'Translation' form input field into my translation record as the 'meaning' field. No matter what I have tried.

Hoping you can figure this one out for me.

Thanks.
