Lab 7 - Issues & Observations

[t-siddharth]

Thanks for the comparison examples and the exercises. Here are some observations that might help others:

Observation 1 - Use IRB

For part 3 of the README.md, there should be an instruction/tip to use IRB right before this statement:

require '~/devrampup/week7/example_ruby_scripts.rb'

A possible replacement:

Type IRB at the command prompt to launch the Interactive Ruby Shell. Then enter the following command, though replace the command path with the absolute path to the directory where the example ruby scripts file lives:
require '~/devrampup/week7/example_ruby_scripts.rb'

---

Observation 2

Not sure if these commands were meant to be tried out - they give the following error messages:

1.9.3p327 :017 > name = params['name']

1.9.3p327 :017 > name = params['name']
NameError: undefined local variable or method params' for main:Object from (irb):17 from /usr/local/bin/irb:12:in

'

1.9.3p327 :018 > Blog.posts.where(‘author.name = ?’, name)

1.9.3p327 :018 > Blog.posts.where(‘author.name = ?’, name)
NameError: uninitialized constant Blog
from (irb):18
from /usr/local/bin/irb:12:in `

Bonus section

Observation 3

Start getting error messages from the git fetch master command:
$ git branch
/* feature/cool_feature
master

$ git fetch master
fatal: 'master' does not appear to be a git repository
fatal: Could not read from remote repository.

$ git status
"# On branch feature/cool_feature"
"nothing to commit, working directory clean"

Observation 3b

Error messages continue from that fetch command point in the bonus file:
$ git checkout master
Switched to branch 'master'
$ git pull origin master
shell-init: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory

Hey @siddtewari thanks for the comments; I've updated a few things.

1. You're right that you have to open the ruby interpreter with irb before you can run the 'require' command. I've updated the readme.

2. Those commands should not work--they were just hypothetical; consider them a sneak-peek of some magic to come...

3a) It should be git fetch origin...my bad. Sorry about that.

3b) I need to see your origin...can you post the output of your 'git remote -v'?

Thanks!

Yes, though it's probably more correct to think of it as array is assigned the 'value' [3,1,2], rather than overwritten, since the variable 'array' is actually the same object after the sort!

Thanks, Dean! That's good to know.
