headcount's Issues

Parser Class

Takes in csv file - future needs data directory input. Create instance inside of parser inside DistrictRepo

Output - properly formatted data for DR class

This is functionally the DISTRICT Parser. Needs to be renamend

statwidetest_objects_remaining_tests

Need a few more tests showing extra data on the objects

it2_statewide_objects

WIP
Created initial StatewideTest object and StatewideTestRepository objects. Initial tests started.

Going to store data on Statewide tests as @DaTa = hash.

Need to determine structure of data hash on the object before continuing.

sdsa

sdfsd

duplicate methods in enrollment and statewide parsers

def truncate(float)
(float * 1000).floor / 1000.to_f
end

def convert_na(value)
if value == "0" || value == "1"
return value.to_f
end
float = value.to_f
value == float.to_s ? truncate(value.to_f) : nil
end

EnrollmentRepository Cleanup

file assignment needs to be modified to accept full hash

Instance of parser may change depending on final parse

Tests look ok

statey_parser_b

New statewide parser.
Should be able to be adjusted to handle all 5 file types. Look at hashyhash method.
Includes truncated float values! - Move forward with this.
Deals with oddball values for data. Converts anything not a float to N/A. Will throw errors that we will need to deal with in future methods.

integrate_dr_with_swtest_objects

Create relationship layer between District Repo and Statewide Objects. Loading data to the DR will trigger the creation of a SWTRepo, SWTobjects, tie them with district objects

final_file_cleanup

Clean up files
Remove bindings
Remove comments
Remove running code at the bottom of files

it2_analyst

change_to_require_relatives

All requires in lib folder needs to be changed to relatives

EnrollmentParser Class

Need to complete Parsing code to provide next hash with combined enrollment data

statewidetest_methods

Enrollment Parser

The parser needs to be finished/completed
Use headers to grab data instead of splitting on strings

Tests need to be written

Move Parser from ER to DR

This may make it easier to test a few methods

Modify Parser Class

1. Rename as DistrictParser Class
2. Rename ParserTest to DistrictParserTest
3. Change "split" method to use headers to access data => line[:Location], line[:Data], etc

Round test number to 3 digits

Data is rounded in parser.

district_rep_tests

Needs new tests to cover refactored methods and methods for statewide test repo objects

Enrollment Repository Class

Input - csv file (for now)
Methods -> find_by_name - case insensitive search
Creates instances of enrollments for each district name.

it0_tests

District could use more tests. High_school_grad data

District_rep - tests showing adding high school data

Enrollment parser - Needs 1 test for file_converter.
Rename NA method to nil. Needs test for convert_na - Nil functionality. and additional functionality - floats to strings

Enrollment - Test names need to be adjusted for not rounding
Kindergarten changed to Kgt_participation
Needs tests showing High school grad data

statewide_parser_tests

Need testing for parser

Create Relationship layer

1. Creation of DR initiates creation of ER.
2. ER automatically creates Enrollmnts
3. Enrollments are placed in District objects when Districts are instantiated. Stored as instance variables inside each District as @enrollment

remove_na_from_enrollment_repo

Also need to exclude bad data from being added to enrollment objects

statewidetest_repository_tests

Need more tests

Headcount Analyst It0

WIP

Need tests and all functions

Cleanup District Repo Class

redefine file variable to accept full hash

create district call needs to change - this should be created from Enrollment collection. only need name.
After Districts are created....add enrollment instance varable to each district instance

Test class should be ok?

District Repository

Function - Collection Districs
Input - through dr.load_data(:key_value => csv file)
Creates Parser instance
sends file to parser - output
receives parsed data from Parser - format?
Iterates through collection creates new instance of district for each District name

find_by_name
find_all_matching

Enrollment Parser Tests

enrollment_parser_send_meth

adjust create to use send method instead of hardcoding keys

sanitation_line_length

Sanitation for IT 0 and 1

state_wide_data_parser_delete

Can we delete this file?

Enrollment class

An Enrollment instance holds the enrollment data for a single district

init like so:
e = Enrollment.new({:name => "ACADEMY 20", :kindergarten_participation => {2010 => 0.3915, 2011 => 0.35356, 2012 => 0.2677})

def kindergarten_participation_by_year
returns a hash of key: years and values: percentage

def kindergarten_participation_in_year(year)
returns percentage (fixnum)

final_rake_sanitation_cleanup

rake sanitation:all

add comment to any long lines that are due to required method calls

District Class

district instantiates:
d = District.new({:name => "ACADEMY 20"})
def name

returns upcased string name of district

instances generated my district repo

District Class Cleanup

Remove @year and @enrollment variables
Tests - Remove enrollment and year tests

enrollment_parser_truncate

Change enrollment parser to deal with truncation instead of rounding.

All tests will need to be adjusted as well in multiple files.
