argh @MattChan sometimes I really hate Ruby

user11126

haha

Ivo Flipse

I just have no idea what all the method names are I'm looking for

user11126

the docs can be confusing... especially if you just jump right into rails

user11126

sometimes i still get confused whether something is part of ruby or rails

Ivo Flipse

I have to write a Cucumber test case that 'goes to the edit page' for a certain movie title

but then I have to find the id that goes with this title

I 'think' I've managed to figure out how to get the object of that movie, but then I have to get out the id and interpolate a string that's the path

without using print statements to check what the heck its doing

perhaps I should turn on the debugger and have a peak inside

user11126

5:47 PM

you're debugging a test?

Ivo Flipse

hehe, I have no idea what stuff I have access to

user11126

oh hey there's blood coming out of my nose

user11126

brb

Ivo Flipse

woops...

user11126

okay back

Ivo Flipse

5:51 PM

I somehow managed to get it working :P

user11126

all dried... must be the air and summer weather

Ivo Flipse

hope your nose stopped bleeding by the way :P

user11126

what did you do to get it working?

Ivo Flipse

when /^the edit page for "(.+)"/
  m = Movie.find_by_title($1)
  "/movies/#{m.id}/edit"

but now I want to query my activerecord model to get the director from a certain movie

no clue how to make it search by movie title

user11126

Movie.find_by_director "someone" ?

user11126

5:54 PM

oh, you mean like @movie.director?

Ivo Flipse

ah now I get where that find_by_ ... comes from

yeah, I previously used something silly I saw somewhere, which probably return an array, rather than the object

and that array obviously didn't have an attribute called director

user11126

find_by_attr also returns nil if it can't find the object for you

user11126

whereas find(:id) raises an exception if no records match

Ivo Flipse

expected #<String:103694550> => "Ridley Scott"
got #<String:103688790> => "Ridley Scott"

D'oh!

@movie.director.should be arg2 doesn't work as I expected

user11126

hmm.... different instances?

user11126

5:57 PM

they don't point to the same obj in memory?

Ivo Flipse

well yeah, one is the one I got from the database, the other is arg2

Compared using equal?, which compares object identity,
      but expected and actual are not the same object. Use
      'actual.should == expected' if you don't care about
      object identity in this example.

user11126

i see

Ivo Flipse

now everything passes :)

Feature: search for movies by director

  As a movie buff
  So that I can find movies with my favorite director
  I want to include and serach on director information in movies I enter

Background: movies in database

  Given the following movies exist:
  | title        | rating | director     | release_date |
  | Star Wars    | PG     | George Lucas |   1977-05-25 |
  | Blade Runner | PG     | Ridley Scott |   1982-06-25 |
  | Alien        | R      |              |   1979-05-25 |
  | THX-1138     | R      | George Lucas |   1971-03-11 |

That was my test case

now I have to implement two others, and actually make them work

because I'm rather flabbergasted the update step 'did' something

ah yeah, the update function is pretty generic, so I reckon it should work

user11126

cool

Ivo Flipse

The second lets you click a new link on a movie details page "Find Movies
With Same Director", and shows all movies that share the same director as the
displayed movie. For this you'll have to modify the existing Show Movie view,
and you'll have to add a route, view and controller method for Find With Same
Director.

That's my next assignment

spark-university.s3.amazonaws.com/berkeley-saas/homework/…

pfff, what a way to get these tools shoved down your throat :P

user11126

6:02 PM

heh, it's the best way to learn

user11126

and easily be frustrated

user11126

Ivo Flipse

well, I have to write a 'spec' though I'm not sure how that works :P

@MattChan lol

user11126

ew, specs... i don't like writing stuff....

user11126

rspec? i don't know how that works

Ivo Flipse

6:05 PM

holy smokes, I just updated my view and BAM there's my director column

I like that

@MattChan me neither, so only one way to find out

hi @VPeric

VPeric

Hullo @Ivo

Ivo Flipse

@VPeric I got my ass kicked by the PGM and NLP homework, boy that's a little out of my comfort zone

thank god for Github :P

VPeric

Haven't yet had a chance to look at NLP, I was on the mountains for the weekend.

Ivo Flipse

@VPeric I thought I'd hate it, but the probability stuff they do is pretty related to the other courses

its just the regex that I haven't wrapped my head around yet

VPeric

And actually, the enrollment closed March 18th, so I guess I'm not taking it after all.

So, I have just Algorithms and Game Theory then.

Ivo Flipse

6:09 PM

Well I watched a video of GT, and decided it wasn't for me

VPeric

I have it in school right now, actually, so I figured it'd be useful.

I was really interested in NLP too, but.. ah well.

Ivo Flipse

the same for Crypto

@VPeric I can always send you the material

the assignment was quite interesting

user11126

natural language processing?

VPeric

@MattChan Yep.

@IvoFlipse Perhaps, sure, is it really that interesting?

user11126

@IvoFlipse did you see that flag?

Ivo Flipse

6:12 PM

@MattChan on Fitness? yeah, I wanted to leave it for y'all :P

@VPeric we had to parse random files for email addresses and phone numbers

user11126

and @NathanWheeler just went on vacation

Ivo Flipse

I had no idea how to tackle it, but a github repo gave me the solution, so I studied that instead

there's also Greg

VPeric

@IvoFlipse I once saw a regex for parsing all legal e-mails.. it's huge.

user11126

regex is awesome

VPeric

yep :D

user11126

6:20 PM

@IvoFlipse i should send you my "compressed and obfuscated" perl program

user11126

we had a project in our class where we had to use perl to parse Doom 3 deathmatch log files

user11126

and there were three different contests.... i won the one for shortest perl program

user11126

our lecturer opened it up in class and everyone just flipped out

user11126

i'll dig it up later tonight, gotta head out now for a dentist appointment

Ivo Flipse

@MattChan good luck

@VPeric well this one wasn't really large, but it got a perfect score

VPeric

6:25 PM

@IvoFlipse Nice; it's because the standard is actually so huge, most addresses could probably be caught by a simple regex.

Ivo Flipse

github.com/peterwilliams97/nlp_class

VPeric

Oh, I've got a new homework from an AI class too, it's to write a player playing Gobblet (something like 3-d "connect 4")

Ivo Flipse

how did you end up solving the nonogram?

VPeric

Badly.. as in, I didn't solve it. :)

But my approach was the right one.

Ivo Flipse

awh too bad

the CSP one? well if you didn't solve it, it wasn't entirely ;P

to cheer you up, I haven't solved robotics homework for this week yet

VPeric

6:33 PM

Well, good start, I just should have implemented more checking methods to further restrict the domain.

right, lets move this to Fake Programmers

Ivo Flipse

10:06 PM

What the hell, Cucumber has been working all evening and now it decides to crap out on me?!?

freiheit

@VPeric The simple regex is wrong unless it's REALLY simple. "Is there stuff on both sides of an '@'? yes. good to go!"

if(m/.\@./) { # good } else { # bad or at least old-fashioned enough to be worth rejecting }

Ivo Flipse

10:21 PM

@freiheit notice anything strange in this error message: pastebin.com/7CZJa38A

its about as generic as they can get :S

freiheit

@IvoFlipse that looks pretty typical for a language parsing error to me... I'd look on line 3 of js_dsl.js. Looks like an unbalanced block or quote

Ivo Flipse

Yeah, if only it would mention which file...

Ivo Flipse

10:38 PM

what the hell @freiheit, the problem was in the output, which gets generated

freiheit

@IvoFlipse So, then, not in a file?

Ivo Flipse

well that creates a ton of files, no idea why it started giving problems :(

I blame github :P

Ivo Flipse

11:23 PM

@Sklivvz you tell me if that calculator is any good, if they don't give more information, than how am I supposed to know?

Sklivvz

11:59 PM

@IvoFlipse I don't know - you are the experts on nutrition and fitness, surely you can give me some idea on where the original resources are?

Ivo Flipse

@Sklivvz I was merely mocking you, since its very Skeptical of you to ask it :P
