Jason, glad you've got things working! :)
No, you don't want to try showing that many records on screen all at
once. Well at least not if you're letting web2py format it
automatically, in experimenting with my own good sized datasets I've
found that if you code out the table yourself in a view it
Cool! That seemed to be importing properly. I have to be careful with
displaying that much data in my browser. Actually filled my 2gb of ram!
One more small thing to note here is that it doesn't account for old
paint names in the database. So running the same file twice dupplicates,
what seems t
Jason, put your csv file in the private subfolder of your application
and call it "paint.csv" and then add the following code to your
controller and it should work. (Well at least it imported the few
records you provided, I haven't taken the time to totally check that
everything lines up.

Your requested some more data...

"10 JORASDUN",C,DD1,56,fS1,42,So1,110,AA1,8,,
"10 SVFGH",W,To1,180
1002-DG5R,R,Co2,30,la1,4,To1,5
1008-Y24R,A,DD2,88,la1,17,Fo1,
Using only what I know I have implemented this...
def rebuild_database:
import sys
data = open("/home/jason/Desktop/colorant_tints.txt")
parsed_data = []
for line in data.readlines():
parsed_data.append(line.rsplit(","))
sys.stdout.write(".")
for line in parsed_d
It seems to give me the error:
type error '_csv.reader' object is unsubscriptable

paint_formulas is supposed to get the contents of the csv file. (See
http://docs.python.org/library/csv.html) It should be populated by the
line:
paint_formulas = csv.reader(csvfile)
where csv file should be the path to your csv file.
Actually, I think that line should read like this instead:
It is much more understandable. But it seems that the name
paint_formulas is not defined. What is supposed to be populated there?

Jason,
What's the syntax error?
Try this, it's untested but should be verbose enough to get you there.
If you have trouble perhaps provide a sample file (few dozen records)
that we can test against.
import csv
paint_formulas = csv.reader(csvfile)
header = None
#variable to store the paints we've
I tried the script but couldn't get through the syntax error. Sorry,
lots of commands I don't know there. :/

I have been working on using web2py to import csv files and find that
in general it works very well. You will need to be careful with
pulling in the colorant and amount fields - if you use the
csv.DictReader() to refer to columns in the CSV file by name instead
of index you'll find that you only ge
Something like this?
import csv
reader = csv.reader(csvfile)
header = None
paints = {}
colorants = {}
for line in reader:
if not header: header = line
else:
row = dict([header[i],item) for i,item in enumerate(line)])
name = row['Color Name']
colorant = row['Colorant
