Hi all !
Is it normal that we have always the same screen on the right side . Shouldn’t we see the different APP element take place ? It was the same in the previous . Did I made something wrong ?
I recommend doing an online search for errors like these. If you do that, you’ll see that you need to run this command in the terminal to fix the first one:
$ bundle exec rake db:migrate
For the second error, it means that a certain item doesn’t have a name column in the database, but you’re trying to access it anyway. See if you can find where you’re accessing something .name, then check if it should be .title or something else instead.
can I write this code bundle exec rake db:migrate at any moment of the process ?
Yes, but most of the time there’s no reason to unless you’ve changed your db/migrate files.
isn’it because there are precise term "first-name " “last_name” and not general term in the database “name” ?
That might be it, but I don’t know what you’re calling .name on. Find that, then figure out which table in the database it belongs to (actors, movies, etc.), then look at what properties it does have that you need to use instead.
That’s correct, there’s no .name method, which is what the error undefined method \name’ for nil:NilClass` means. Go to the terminal for the exercise (black area with blinking white cursor), and run these commands:
$ cd ~/workspace/learn-rails-many-to-many/
$ grep -r "\.name"
@slibre2 The dollar sign ($) only represents the bash prompt, you’re not supposed to actually type it. Could you do it again, and not type the $ this time please?
