Joomla K2 content sort by number of votes - joomla

I'm using Joomla 2.5 and K2 2.5.7. I have a category with posts with a different number of votes. In the front end, I need to sort the items of this category by number of votes.
I re-configured standard stars rating systems to simple "Give one vote" system.
I need this for a ranking order page, so it will have items with the largest number of votes on the top.
What I have
I have my MVC template for K2 category. I was wondering, if sorting $this->leading in category.php is the right to go for.
If it is, how can I do it? With var_dump there is variable numOfVotes which carry real number of votes. How can I sort this object by this var?
Thank you very much!

This K2 forum post seems to answer your question. You need to use the mod_content k2 module and use the "sort by" parameter and select highest rating.
If you go to 'modules/mod_k2_content/helper.php' in the ftp, you'll see on line 98, that there it says
$query .= ", (r.rating_sum/r.rating_count) AS rating";
This sorts the data by the highest rating. Now generally this would sort it by the number of votes divided by the number of people who have voted giving a result between 1 and 5. However as everyone in your case gets a vote of 5 - then your average result will always be 5 by that calculation!, I think that you'll have to replace that line with:
$query .= ", r.rating_count AS rating";
i.e. just sorting by the number of people who have voted (N.B. This assumes you're not using a vote down system as well! You haven't mentioned it so I'm assuming not)
Then you should just be able to use the module (selecting the parameter that you desire as normal)
For using the component category option etc. Then the same line of code can be found in 'components/com_k2/models/itemlist.php' on Line 39 which again would need to be edited. Then you could just use the built in parameters as usual!

Is there a way to filter and return results for the unique of one column, with conditions of another?

Question
For the data below, is there a way to return results —for each order in col B— either:
If the most recent status [col D] for an order (ex. for order 10021) is closed, then return that row.
If not, return every row since the most recent closed status for that order (ex. for order 10020, rows 4 and 5).
Previous efforts and attempted solutions
Previously, I was only returning one result, the most recent status for each order with the following:
=SORTN(SORT(A2:D,1,FALSE),9^9,2,2,FALSE)
However, I would like if orders can have more than one current status.
I've tried a few things, and was able to achieve what I'm looking for, unfortunately only if there is one order, with the following:
(The linked sheet below explains how I got to this)
=IFERROR(FILTER(A2:D5,A2:A5>INDEX(SORT(FILTER(A2:D5,D2:D5="CLOSED"),1,0),1,1)),FILTER(A2:D5,A2:A5>=INDEX(SORT(FILTER(A2:D5,D2:D5="CLOSED"),1,0),1,1)))
The other alternative I can think of is a script with a loop.
Summary
It was difficult to know how to title this question but came to it since essentially we're trying to filter for the unique of col B, with conditions against col A & D.
Here's a link to a sample Google spreadsheet you can edit, showing all the attempts.
All your help and comments are greatly appreciated!
maybe like this:
=ARRAYFORMULA(UNIQUE(SORT({VLOOKUP(UNIQUE(INDIRECT("B2:B"&COUNTA(B2:B)+1)),
SORT({B2:B, TO_TEXT(A2:D)}, 2, 0), {2, 3, 4, 5}, 0);
FILTER(A2:D, D2:D="RETURN")},1,1)))
Solution
All credit to Matt King who found a complete answer.
=ARRAYFORMULA(QUERY({A:D,(COUNTIFS(C:C,C:C,A:A,">="&A:A)=1)*(D:D="CLOSED")
+NOT(REGEXMATCH(TRIM(TRANSPOSE(QUERY(IF((TRANSPOSE(A:A)<=A:A)*(TRANSPOSE(C:C)=C:C),D:D,)
,,9^99))),"CLOSED"))},"select Col1,Col2,Col3,Col4 where Col5=1"))
Essentially,
First assigning a count to each row for any given order
Transpose and combine statuses
If there is a CLOSED status in there, don't use it
Then filter with query language
Resulting in—
See solution here.
Mod
I added a clause to completely exclude the status NOTE from current records—
=ARRAYFORMULA(QUERY({A:D,(COUNTIFS(B:B,B:B,A:A,">="&A:A)=1)*(D:D="CLOSED")+
(ARRAYFORMULA(IF((ARRAYFORMULA(NOT(REGEXMATCH(TRIM(TRANSPOSE(QUERY
(IF((TRANSPOSE(A:A)<=A:A)*(TRANSPOSE(B:B)=B:B),D:D,),,9^99))),"CLOSED"))))
=TRUE,IF((ARRAYFORMULA(NOT(TRANSPOSE(ARRAYFORMULA(TRANSPOSE(D:D)))="NOTE")))
=FALSE,FALSE,TRUE),FALSE)))},"select Col1,Col2,Col3,Col4 where Col5=1"))
Implementation
This was sample tested against 2500 rows of data, and took over 80 seconds to execute. So although this answers the question, it isn't necessarily a viable solution.

Reporting Multiple Values & Sorting

Having a bit of an issue and unsure if it's actually possible to do.
I'm working on a file that I will enter target progression vs actual target reporting the % outcome.
PAGE 1
¦NAME ¦TAR 1 %¦TAR 2 %¦TAR 3 %¦TAR 4 %¦OVERALL¦SUB 1¦SUB 2¦SUB 3¦
¦NAME1¦ 114%¦ 121%¦ 100%¦ 250%¦ 146%¦ 2¦ 0¦ 0%¦
¦NAME2¦ 88%¦ 100%¦ 90%¦ 50%¦ 82%¦ 0¦ 1¦ 0%¦
¦NAME3¦ 82%¦ 54%¦ 64%¦ 100%¦ 75%¦ 6¦ 6¦ 15%¦
¦NAME4¦ 103%¦ 64%¦ 56%¦ 43%¦ 67%¦ 4¦ 4¦ 24%¦
¦NAME5¦ 87%¦ 63%¦ 89%¦ 0%¦ 60%¦ 3¦ 2¦ 16%¦
Now I already have it sorting all rows by the Overall % column so I can quickly see at a glance but I am creating a second page that I need to reference points.
So on the second page I would like to somehow sort and reference different columns for example
PAGE 2
TOP TAR 1¦Name of top %¦Top %¦
TOP TAR 2¦Name of top %¦Top %¦
Is something like this possible to do?
Essentially I'm creating an Employee of the Month form that automatically works out who has topped what.
I'm willing to drop a paypal donation for whoever can figure this out for me as I've been doing it manually every month and would appreciate the time saved
I don't think a complicated array formula is necessary for this - I am suggesting a fairly standard Index/Match approach.
First set up the row titles - you can just copy and transpose them from Page 1, or use a formula in A2 of Page 2 like
=transpose('Page 1'!B1:E1)
The use them in an index/match to get the data in the corresponding column of the main sheet and find its maximum (in C2)
=max(index('Page 1'!A:E,0,match(A2,'Page 1'!A$1:E$1,0)))
Finally look up the maximum in the main sheet to find the corresponding name:
=index('Page 1'!A:A,match(C2,index('Page 1'!A:E,0,match(A2,'Page 1'!A$1:E$1,0)),0))
If you think there could be a tie for first place with two or more people getting the same score, you could use a filter to get the different names:
So if the max score is in B8 this time (same formula)
=max(index('Page 1'!A:E,0,match(A8,'Page 1'!A$1:E$1,0)))
the different names could be spread across the corresponding row using transpose (in C8)
=ArrayFormula(TRANSPOSE(filter('Page 1'!A:A,index('Page 1'!A:E,0,match(A8,'Page 1'!A$1:E$1,0))=B8)))
I have changed the test data slightly to show these different scenarios

Magento Option Question

This seems simple enough in theory but I haven't found anything on it. I need it for a client. Please see this page as an example: http://www.customsportsteamuniforms.com/index.php/test-shirt.html
On that page, you will find the first option that says "What kind of Screen Printing do you want?" If you select 1 color and you also happen to want more than 1 quantity (let's say 5), you will end up with this formula for the product cost:
$5 (cost) x $25 (option) x 5 quantity = total.
I DO NOT want it to do that. The option should be a one time fee in this case. The formula should read:
$5 (cost) x 5 quantity = sub-total + $25 (option) = total
How do I do this?
Magento's additional fees are all calculated on a per-product basis. If you want to add a fee to the entire order, you'll need to add some custom code to add this as a sort of handling fee for the order. The semantics for this are up to you (for instance, what about 2 different shirts both with 1-color screen printing options).
I found a plugin that does this:
http://www.absolutepricing.com/
Although, in my opinion, this should have been part of the system to begin with, but that's neither here nor there...

mortgage calculator in Shoes but it won't divide?

I am new to Ruby and Shoes, I think I have everything. the program appears to work correctly except when I get to the last step. I, enter the loan amount, interest rate, in to edit_lines, when I press the calculate button, it performs the calculations, stores the calculated numbers to a variable. The last step is dividing the total loan (loan and interest) by the length of the loan in months to ge the monthly payment, so I can make a payment table for the entire loan, but I either get in-corredt results or I get no reeults.
I think I converted the integers to floats, etc. , but... not sure. It appears to add, multiply, subtrct, except it will not divide 2 qbjects. If I enter numbers it works ok.
What am I doing wrong. It does seem like it is that difficult. Example code of dividng the values in a varible by the value of another varible?
It looks like you're using eval(), which you almost never, ever want to use. You can do the exact same thing in normal ruby. I'm just guessing right now since the code I can see in your comment is lacking newlines, but I think this code would work:
#numberbox3.text = #totalinterest + #loadamount
#numberbox5.text = #totalloan / #lengthyears
Hope this helps!

Algorithms or Patterns for reading text

My company has a client that tracks prices for products from different companies at different locations. This information goes into a database.
These companies email the prices to our client each day, and of course the emails are all formatted differently. It is impossible to have any of the companies change their format - they will not do it.
Some look sort of like this:
This is example text that could be many lines long...
Location 1
Product 1 Product 2 Product 3
$20.99 $21.99 $33.79
Location 2
Product 1 Product 2 Product 3
$24.99 $22.88 $35.59
Others look sort of like this:
PRODUCT       PRICE   + / -
------------  -------- -------
Location 1
1             2007.30 +048.20
2             2022.50 +048.20
Maybe some multiline text here about a holiday or something...
Location 2
1             2017.30 +048.20
2             2032.50 +048.20
Currently we have individual parsers written for each company's email format. But these formats change slightly pretty frequently. We can't count on the prices being on the same row or column each time.
It's trivial for us to look at the emails and determine which price goes with which product at which location. But not so much for our code. So I'm trying to find a more flexible solution and would like your suggestions about what approaches to take. I'm open to anything from regex to neural networks - I'll learn what I need to to make this work, I just don't know what I need to learn. Is this a lex/parsing problem? More similar to OCR?
The code doesn't have to figure out the formats all on its own. The emails fall into a few main 'styles' like the ones above. We really need the code to just be flexible enough that a new product line or whitespace or something doesn't make the file unparsable.
Thanks for any suggestions about where to start.
I think this problem would be suitable for proper parser generator. Regular expressions are too difficult to test and debug if they go wrong. However, I would go for a parser generator that is simple to use as if it was part of a language.
For these type of tasks I would go with pyparsing as its got the power of a full lr parser but without a difficult grammer to define and very good helper functions. The code is easy to read too.
from pyparsing import *
aaa =""" This is example text that could be many lines long...
another line
Location 1
Product 1 Product 2 Product 3
$20.99 $21.99 $33.79
stuff in here you want to ignore
Location 2
Product 1 Product 2 Product 3
$24.99 $22.88 $35.59 """
result = SkipTo("Location").suppress() \
# in place of "location" could be any type of match like a re.
+ OneOrMore(Word(alphas) + Word(nums)) \
+ OneOrMore(Word(nums+"$.")) \
all_results = OneOrMore(Group(result))
parsed = all_results.parseString(aaa)
for block in parsed:
print block
This returns a list of lists.
['Location', '1', 'Product', '1', 'Product', '2', 'Product', '3', '$20.99', '$21.99', '$33.79']
['Location', '2', 'Product', '1', 'Product', '2', 'Product', '3', '$24.99', '$22.88', '$35.59']
You can group things as you want but for simplicity I have just returned lists. Whitespace is ignored by default which makes things a lot simpler.
I do not know if there are equivalents in other languages.
You have given two pattern samples for text files.
I think these can be handled with scripting.
Something like: AWK, sed, grep with bash scripting.
One pattern in the first sample,
Section starts with keyword Location [Number]
second line of section has columns describing product names
third line of section has columns with prices for the products
There can be variable number of products per section.
There can be variable number of sections per file.
Products and prices are always on their designated lines of a section.
Whitespace separation identifies the (product,price) column-association.
Number of products in a section matches the number of prices in that section.
The collected data would probably be assimilated in a database.
The one thing I know I would use here is regular expressions. Three or four expressions could drive the parse logic for each e-mail format.
Trying to write the parse engine more generally than that would, I think, be skirting the edge of overprogramming it.
