This isnt a lab, more like a read along, but i found myself trying to decode this error message with the help of students and instructor Dylan. It seems as though we could not find a solution to what's going on with this error. I can not use learn or rspec or it will raise this error. If someone can help explain why this is going on, that would be helpful since all I did was fork and copy and ran rspec. I did not change any code except the one line in the model class.

All of the tests pass without modifying any files.

Maybe remove some code and at least make it a somewhat active, copy-and-paste code-along?

The before_validation statement is already put in for you, but it's not supposed to be there until you get further down in the lab. You're actually supposed to write it in yourself.

Because of this, the Post.create doesn't behave as described in the lab. (It works when it "shouldn't" work.)

On line 36 of post_spec.rb ,it says:
expect(page).to have_content("My edit")

It should expect "My Edit", with a capitalized "Edit", since it is being automatically capitalized before being validated.

when you click on it as though you are finished reading and then go on to the next lesson the website will not persist the fact that it is completed (ie the green light will not stay green after a refresh).

I went ahead and forked the lab down to my computer and made the changes and then did a pull request. Then I clicked the button as though I was finished reading and it did persist this time (ie the light stayed green even after a page refresh).

basically the page is requiring that you fork - pass - pull the lab to get credit for it but the page only shows the "finished reading" button (as though you don't need to fork - pass -pull on this lab.

trivial but confusing nonetheless. It would be best to either get the page to reflect that it actually a fork - pass - pull lab and not just a read lab.

thanks,

The tests were failing because no code for routes was included. Since this felt like a walk-through lab, maybe this was an oversight?

line#180

Currently:
[callbacks]: http://guides.rubyonrails.org/active_record_callbacks.html**.**

Should be:
[callbacks]: http://guides.rubyonrails.org/active_record_callbacks.html

Current code:

def update
	  @post = Post.find(params[:id])
	  @post.update(params.require(:post))
	  redirect_to post_path(@post)
	end

It gives me this error:

 1) form shows an update form that submits content and redirects and prints out params
     Failure/Error: @post.update(params.require(:post))
     
     ActiveModel::ForbiddenAttributesError:
       ActiveModel::ForbiddenAttributesError

What worked for me:

	def update
	  @post = Post.find(params[:id])
	  @post.update(params.require(:post).permit!)
	  redirect_to post_path(@post)
	end

I also don't understand why the routes aren't written in this ReadMe. If it's a ReadMe and it's not teaching routes, they should be written so we can focus on the material being taught. It's distracting.

Specify that rake db:migrate is needed

Hi there! I received this error when trying to follow along with the instructions for this code-along while inside rails c running this command:

p = Post.create(title: "testing")

Error below:

It wasn't the output that was described in the lesson.

Hope this helps! Thanks again :-)

This was a readme. upon running learn i got this error

Failures:

1. form shows an update form that submits content and redirects and prints out params
   Failure/Error: expect(page).to have_content("My Edit")
   expected to find text "My Edit" in "My Post\nMy post desc"

in the spec it has:

describe 'form' do

it 'shows an update form that submits content and redirects and prints out params' do
@post = Post.create(title: "My Post", description: "My post desc")

visit edit_post_path(@post)

fill_in 'post[title]', with: "My edit"
fill_in 'post[description]', with: "My post description"

click_on "Update Post"

expect(page).to have_content("My Edit")

end
end

the fill in for "My edit" has lowercase e. i had to alter the test to uppercase to get it to pass

line 36 spec/features/post_spec.rb

we must should note that

Should or must, not must should :D
