  • In Django how display all of the values aftere the for loop is finished instead of displaying them one by one

    - by Igor
    Hello, In my django project in the view I call the last 6 values in the column and send them to the template. I then would like to pass into google charts api those 6 values and have a graph. At the moment for some reason I get 6 different graphs. {% for foodbag in foodbags %} <img src="http://chart.apis.google.com/chart?chxl=0:|0|1|2|3|4|5|6&chxr=2,0,0&chxs=0,1,676767,10.5,1,l,676767|2,676767,5.5,0,l,676767&chxt=x,y&chs=300x170&cht=bvg&chco=76A4FB&chd=t:{{foodbag.12}},0&chma=0,5|5,5&chdlp=t&chtt=Food+Bags"/> {% endfor %} I'm not sure how to replace string chd=t:{{foodbag.12}}, with the 6 values I am trying to extract from foodbags. I would really appreciate the help. Thank you

  • how to pass an xml file to lxml to parse?

    - by BeeBand
    I'm trying to parse an xml file using lxml. xml.etree allowed me to simply pass the file name as a parameter to the parse function, so I attempted to do the same with lxml. My code: from lxml import etree from lxml import objectify file = "C:\Projects\python\cb.xml" tree = etree.parse(file) but I get the error: Traceback (most recent call last): File "cb.py", line 5, in <module> tree = etree.parse(file) File "lxml.etree.pyx", line 2698, in lxml.etree.parse (src/lxml/lxml.etree.c:4 9590) File "parser.pxi", line 1491, in lxml.etree._parseDocument (src/lxml/lxml.etre e.c:71205) File "parser.pxi", line 1520, in lxml.etree._parseDocumentFromURL (src/lxml/lx ml.etree.c:71488) File "parser.pxi", line 1420, in lxml.etree._parseDocFromFile (src/lxml/lxml.e tree.c:70583) File "parser.pxi", line 975, in lxml.etree._BaseParser._parseDocFromFile (src/ lxml/lxml.etree.c:67736) File "parser.pxi", line 539, in lxml.etree._ParserContext._handleParseResultDo c (src/lxml/lxml.etree.c:63820) File "parser.pxi", line 625, in lxml.etree._handleParseResult (src/lxml/lxml.e tree.c:64741) File "parser.pxi", line 565, in lxml.etree._raiseParseError (src/lxml/lxml.etr ee.c:64084) lxml.etree.XMLSyntaxError: AttValue: " or ' expected, line 2, column 26 What am I doing wrong?

  • Is a masters degree overkill?

    - by Chris
    After reading the responses to Is a College/University Degree Still Relevant?, I'd then ask, once you complete a university technology degree, would pursuing a masters in the field be worth it? Or is the experience you would gain working for those two years be more valuable? Or is a masters degree something that is more valuable after one has a few years of real-world experience after their undergrad? And what career doors would a masters open, and which would they possibly close? Keeping in mind this discussion on higher pay for advanced degrees, I'd rate whether a masters is worthwhile by both the pay one would get, but also more importantly, how enjoyable the job would be, and the types available (research only? development? management?).

  • Best ORM, Simple data Structures, Strong Query analysis.

    - by sayth
    What is the best ORM db combination for simple data structures. That is data that contains names as identifiers and locations, but whose main interaction will be numerical data for times(sports durations), and currency related data. I initially want to create a sports data base that will take names and statistics. Secondarily I plan to start into an investment and stock analysis db. Which ORM suits storing many numerical types and have strong query functions? I really am not biased to db engine (most likely use sqlite or mongo) so any suggestions to best network less db server to suit said ORM appreciated.

  • RubyQt Crashing on QTableWidget

    - by gja
    I'm getting some weirdness with QtRuby when using a TableWidget. The table widget loads, but when you click on the elements in the row, the app segfaults and crashes. require 'Qt4' class SimpleModel < Qt::AbstractTableModel def rowCount(parent) return 1 end def columnCount(parent) return 1 end def data(index, role=Qt::DisplayRole) return Qt::Variant.new("Really Long String") if index.row == 0 and index.column == 0 and role == Qt::DisplayRole return Qt::Variant.new end end Qt::Application.new(ARGV) do Qt::TableWidget.new(1, 1) do set_model SimpleModel.new show end exec end The backtrace seems to imply that it is bombing in mousePressEvent #6 0x01624643 in QAbstractItemView::pressed(QModelIndex const&) () from /usr/lib/libQtGui.so.4 #7 0x016306f5 in QAbstractItemView::mousePressEvent(QMouseEvent*) () from /usr/lib/libQtGui.so.4 If I override mousePressEvent and mouseMoveEvent, these kinds of crashes no longer happen. Am I doing something wrong over here, or can I chalk this up as a bug in QtRuby? I'm on fedora11, with the following packages installed: QtRuby-4.4.0-1.fc11.i586 ruby-1.8.6.369-1.fc11.i586 These crashes also happen when running the script on Windows.

  • Why darcs instead of git?

    - by Ctrl Alt D-1337
    Using pure functional languages can have a lot of benefits over using impure imperatives but low level systems languages will generally allow you to achieve much greater performance especially when they are imperative because it allows you to specify the exact steps in how the cpu should compute the result. If there is ever list of tools where high performance is an absolute must then I would put source version controls systems right at the top of that list and git achieves this very well but performance is not it's only advantage over many other other types of version control systems anyway. The git team are handling the unsafe c code very well and I never worry about my type system or any other features of the language it is written in so why is it that there is a lot of haskell developers that must use darcs when they will only be using the finished product?

  • Mysql CASE - WHEN - THEN - returning wrong data type (blob)

    - by Jack
    Hi there. Im creating customizable product attributes in a web store - each attribute can have different type of data, each data type is stored in a separate column using corresponding mysql datatype. I Have a query like: SELECT products.id AS id, products.sku AS sku, products.name AS name, products.url_key AS url_key, attributes.name AS attribute, CASE WHEN `attribute_types`.`type` = 'text' THEN product_attribute_values.value_text WHEN `attribute_types`.`type` = 'float' THEN product_attribute_values.value_float WHEN `attribute_types`.`type` = 'price' THEN product_attribute_values.value_float WHEN `attribute_types`.`type` = 'integer' THEN product_attribute_values.value_integer WHEN `attribute_types`.`type` = 'multiple' THEN product_attribute_values.value_text WHEN `attribute_types`.`type` = 'dropdown' THEN product_attribute_values.value_text WHEN `attribute_types`.`type` = 'date' THEN product_attribute_values.value_date WHEN `attribute_types`.`type` = 'textarea' THEN product_attribute_values.value_textarea END as value from (...) Now, the problem is that when attribute_types.type equals to ?some-type? i want it to return a value as it's stored in product_attribute_values table. Currently I get BLOb every time. Should I use type-casting or there's some behind-the-scene magic that I dont know about, OR maybe there's some better alternative ?

  • PHP - Opening uploaded DOCX files with the correct MIME TYPE

    - by user270797
    I have users uploading DOCX files which I make available for download. The issues we have been experiencing is the unknown mime types of DOCX files which causes IE to open these docs as Zip files. It is running on a Windows/IIS server. Because this is a shared host, I cannot change any server settings. I was thinking that I could just write some code that would handle DOCX files, perhaps custom output: if (extension=docx) { header("Content-Disposition: attachment; etc) header('Content-Type: application/application/vnd.openxmlformats-officedocument.wordprocessingml.document'); Output the file contents etc } Would this be a viable solution?? If so, can someone help fill in the gaps? (PS I know the above syntax is not correct, just a quick example)

  • SharePoint's CAML query the "Created By" field with username

    - by yellowblood
    Hey, I have a form for administrators where they insert a user name ("domain\name") and the code gets and sets some information out of it. It's a huge project and some of the lists contain the username as a string ("domain\name"), but some lists only count on the "Created By" column, which is auto-created. I want to know what's the fastest way to query these lists using the username string. I tried to use the same query as the one I use for the first kind of lists and it obviously didn't work - <Where><Eq><FieldRef Name='UserName'/><Value Type='Text'>domain\\username</Value></Eq></Where> Thank you.

  • "Mem Usage" higher than "VM Size" in WinXP Task Manager

    - by Frederick
    In my Windows XP Task Manager, some processes display a higher value in the Mem Usage column than the VMSize. My Firefox instance, for example shows 111544 K as mem usage and 100576 K as VMSize. According to the help file of Task Manager Mem Usage is the working set of the process and VMSize is the committed memory in the Virtual address space. My question is, if the number of committed pages for a process is A and the number of pages in physical memory for the same process is B, shouldn't it always be B = A? Isn't the number of pages in physical memory per process a subset of the committed pages? Or is this something to do with sharing of memory among processes? Please explain. (Perhaps my definition of 'Working Set' is off the mark). Thanks.

  • How to make a DropDownList control display some items in bold ASP.Net

    - by james lewis
    I'm working with a custom DropDownList control in ASP.Net and there's been a request to display certain items in the list with a bold typeface (NOTE - the control inherits from CompositeDataBoundControl so it can be data bound... not DropDownListBox). The control is bound to a table and there's a column in the table named IsUsed - if this is set to true, the corresponding item in the list should be rendered bold. (It should be noted here that this will only ever be viewed in FireFox.) My experience is all in the middle \ backend tiers so the presentation layer is very new to me - can someone point me in the right direction? My initial thought was that somewhere in the custom control I would have access to all the rows that are returned from the data source which I could cycle through etc but I'm not sure if that's possible... There's also RenderContents which I can override... looks interesting! Any help appreciated - cheers. James

  • How to save the view count of a question in memory?

    - by Freewind
    My website is like stackoverflow, there are many questions. I want to record how many times a question has been visited. I have a column called "view_count" in the question table to save it. If a user visits a question many times, the view_count should be increased only 1. So I have to record which user has visited which question, and I think it is too much expensive to save this information in the database because the records will be huge. So, I would like to keep the information in memory and only persist the number to the database every 10 minutes. I have searched about "cache" in Rails, but I haven't found an example. I would like a simple sample of how to do this, thanks for help~

  • javascript/jquery input fields cleanup

    - by user271619
    I've created a few input fields, that I am cleaning up as the user types. So, I'm using a keystroke detection event, like .keyup() It's all working very well, but I do notice one thing that's rather annoying for the users. While the script is cleaning the data as they type, their cursor is being sent to the end of the input field. So, if you want to edit the middle of the value, you're cursor immediately goes to the end of the box. Does anyone know of a way to maintain the cursor's current position inside the input field? I'm not holding my breath, but I thought I'd ask. Here's the cleanup code I'm using: $(".pricing").keyup(function(){ // clean up anything non-numeric **var itemprice = $("#itemprice").val().replace(/[^0-9\.]+/g, '');** // return the cleaner value back to the input field **$("#itemprice").val(itemprice);** });

  • activemq round robin between queues or topics

    - by forkit
    I'm trying to achieve load balancing between different types of messages. I would not know in advance what the messages coming in might be until they hit the queue. I know I can try resequencing the messages, but I was thinking that maybe if there was a way to have the various consumers round robin between either queues or between topics, this would solve my problem. The main problem i'm trying to solve is that I have many services sending messages to one queue with many consumers feeding off one queue. I do not want one type of service monopolizing the entire worker cluster. Again I don't know in advance what the messages that are going to hit the queue are going to be. To try to clearly repeat my question: Is there a way to tell the consumers to round robin between either existing queues or topics? Thank you in advance.

  • DataTable to Object collection

    - by Kenneth Cochran
    I'm working on a data import feature and I've been able to load an excel sheet into a DataTable using Ado.NET with the MSJet db engine. I created a simple one-to-one mapping dialog, in which the user drags column headings from their spreadsheet to a list of object properties. What's stumping me is how to turn each DataRow into a business object. Is there an easy way to do this? If there is a better way than using a DataTable as a middleman I'm open to suggestion? I use NHibernate extensively through out the rest of my program but I couldn't find any attempts to map to an excel spreadsheet. I went with a DataTable because the technique was well documented.

  • Symfony app - how to add calculated fields to Propel objects?

    - by Thomas Kohl
    What is the best way of working with calculated fields of Propel objects? Say I have an object "Customer" that has a corresponding table "customers" and each column corresponds to an attribute of my object. What I would like to do is: add a calculated attribute "Number of completed orders" to my object when using it on View A but not on Views B and C. The calculated attribute is a COUNT() of "Order" objects linked to my "Customer" object via ID. What I can do now is to first select all Customer objects, then iteratively count Orders for all of them, but I'd think doing it in a single query would improve performance. But I cannot properly "hydrate" my Propel object since it does not contain the definition of the calculated field(s). How would you approach it?

  • How to display images from SD card in a GalleryView

    - by OceanBlue
    I am trying to display all the images stored in SD card in a Gallery View. I have tried using the content provider (android.provider.MediaStore.images.Media class), but seem to be getting stuck at a point. Not sure if this is the way to go about it. Here is my code so far: String[] colsNeeded = new String[]{Media._ID, Media.TITLE}; Uri mMedia = Media.EXTERNAL_CONTENT_URI; //Create a cursor using the URI & column names needd Cursor c = managedQuery(mMedia, colsNeeded, null, null, Media.DATE_TAKEN + " ASC"); //What kind of adapter should I create here //that contains images from the cursor?? SpinnerAdapter sa = null; //This is the point I get stuck //Set the adapter of the gallery view Gallery galleryPetPhotos = (Gallery)findViewById(R.id.GalleryPetPhotos); galleryPetPhotos.setAdapter(sa); Just a nudge in the right direction would be greatly appreciated.

  • How to use ORDER BY, LOWER .. in SQL SERVER 2008 with non-unicode data

    - by hgulyan
    Hi, The question is about Armenian. I'm using sql server 2005, collation SQL_Latin1_General_CP1_CI_AS, data mostly is in Armenian and we can't use unicode. I tested on ms sql 2008 with a windows collation for armenian language ( Cyrillic_General_100_ ), I have found here, ( http://msdn.microsoft.com/en-us/library/ms188046.aspx ) but it didn't help. I have a function, that orders hex values and a lower function, which takes each char in each string and converts it to it's lower form, but it's not acceptable solution, it works really slow, calling that functions on every column of a huge table. Is there any solution for this issue not using unicode and not working with hex values manually?

  • Writing annotataion schemas for Callisto

    - by Ken Bloom
    Does anybody know where I can find documentation on how to write annotation schemas for Callisto? I'm looking to write something a little more complicated than I can generate from a DTD -- that only gives me the ability to tag different kinds of text mentions. I'm looking to create a schema that represents a single type of relationship between five or six different kinds of textual mentions (and some of these types of mentions have attributes that I need to assign values to), and possibly having a second type of relationship between the first two instances of the first type of relationship. (Alternatively, does anybody know of any software that would be better for this kind of schema? I've been looking at WordFreak, but it's a little clumsy, and it doesn't support attributes on its textual mentions.)

  • Storing date and time as epoch vs native datetime format in the database

    - by zakovyrya
    For most of my tasks I find it much easier to work with date and time in the epoch format: it's trivial to calculate timespan or determine if some event happened before or after another, I don't have to deal with time-zone issues if the data comes from different geographical sources, in case of scripting languages what I usually get from database when I request a datetime-typed column is a string that I need to parse in order to work with it. This list can go on, but for me in order to keep my code portable that's enough to ditch database's native datetime format and store date and time as integer. What do you guys think?
