  • Inline Form Validation in Django

    - by allanhenderson
    Newbie request that seems difficult to implement. I would like to make an entire inline formset within an admin change form compulsory.. so in my current scenario when I hit save on an Invoice form (in Admin) the inline Order form is blank. I'd like to stop people creating invoices with no orders associated. Anyone know an easy way to do that? Normal validation like (required=True) on the model field doesn't appear to work in this instance. Thanks!!

  • Can this MySQL subquery be optimised?

    - by Dan
    I have two tables, news and news_views. Every time an article is viewed, the news id, IP address and date is recorded in news_views. I'm using a query with a subquery to fetch the most viewed titles from news, by getting the total count of views in the last 24 hours for each one. It works fine except that it takes between 5-10 seconds to run, presumably because there's hundreds of thousands of rows in news_views and it has to go through the entire table before it can finish. The query is as follows, is there any way at all it can be improved? SELECT n.title , nv.views FROM news n LEFT JOIN ( SELECT news_id , count( DISTINCT ip ) AS views FROM news_views WHERE datetime >= SUBDATE(now(), INTERVAL 24 HOUR) GROUP BY news_id ) AS nv ON nv.news_id = n.id ORDER BY views DESC LIMIT 15

  • Core dump utility for .NET

    - by Dave
    In my past life as a COBOL mainframe developer I made extensive use of a tool called Abendaid which, in the event of an exception, would give me a complete memory dump including a formatted list of every variable in memory as well as a complete stack trace of the program with the offending statement highlighted. This made pinpointing the cause of an error much simpler and saved a lot of step-through debugging and/or trace statements. Now I've made the transition to C# and .NET web development I find that the information provided by ASP.NET only tells half the story, giving me a stack trace, but not any of the variable or class information. This makes debugging more difficult as you then have to run the process again with the debugger to try and reproduce the error, not easy with intermittent errors or with assemblies that run under the likes of SQL Server or CRM. I've looked around quite a lot for something that does this but I can't find anything obvious. Does anyone have any idea if there is one, or if not, what I'd need to start with in order to write one?

  • How to find a duplicate element in an array of shuffled consecutive integers?

    - by SysAdmin
    I recently came across a question somewhere Suppose you have an array of 1001 integers. The integers are in random order, but you know each of the integers is between 1 and 1000 (inclusive). In addition, each number appears only once in the array, except for one number, which occurs twice. Assume that you can access each element of the array only once. Describe an algorithm to find the repeated number. If you used auxiliary storage in your algorithm, can you find an algorithm that does not require it? what i am interested to know is the second part. i.e without using auxiliary storage . do you have any idea?

  • How would you start automating my job? - Part 2

    - by Jurily
    (Followup to this question) After surviving the first wave of incoming shipments (9 hours of copy/paste), I now believe I have all the requirements. Here is the updated workflow: Monkey collects email attachments (4 Excel spreadsheets, 1 PDF) Monkey creates central database, does complex calculations (right now this is also an Excel spreadsheet) Monkey sends data to two bosses, who set the retail prices independently; first one to reply wins Monkey sends order form to our other warehouses, also Excel Monkey sends spreadsheets to VIP customers, carefully sanitized and formatted (4 different discount categories) Jurily enters the data into the accounting system. I've given up on automating this part, there's too much business logic involved, and the database is a pile of sh^W legacy My question: What technologies would you use for a quick and dirty solution? I'm mostly sold on C#, but coming from a Linux/C++ background, I'm horribly confused about my choices in Microsoft-land. For bonus points: How would you redesign the whole system from the ground up? P.S. in case you were wondering, my job title is System Administrator.

  • How to save bytes to an image and access it from Bottle

    - by Graham Smith
    I'm working on an API wrapper for Snapchat using Python and Bottle, but in order to return the file (retrieved by the Python script) I have to save the bytes (returned by Snapchat) to a .jpg file. I'm not quite sure how I will do this and still be able to access the file so that it can be returned. Here's what I have so far, but it returns a 404. @route('/image') def image(): username = request.query.username token = request.query.auth_token img_id = request.query.id return get_blob(username, token, img_id) def get_blob(usr, token, img_id): # Form URL and download encrypted "blob" blob_url = "https://feelinsonice.appspot.com/ph/blob?id={}".format(img_id) blob_url += "&username=" + usr + "&timestamp=" + str(timestamp()) + "&req_token=" + req_token(token) enc_blob = requests.get(blob_url).content # Save decrypted image FileUpload.save('/images/' + img_id + '.jpg') img = open('images/' + img_id + '.jpg', 'wb') img.write(decrypt(enc_blob)) img.close() return static_file(img_id + '.jpg', root='/images/')

  • Redis version on Cloudbees is out of date?

    - by Alan Krueger
    I'm setting up an OSS build in Cloudbees with /usr/sbin/redis-server being started as one of the build tasks: + /usr/sbin/redis-server [204] 04 Nov 03:52:58 # Warning: no config file specified, using the default config. In order to specify a config file use 'redis-server /path/to/redis.conf' [204] 04 Nov 03:52:58 * Server started, Redis version 2.0.3 The (Redis site)[http://redis.io/download] shows 2.6.2 to be the current version and 2.4.17 as "legacy". On the extended downloads page, version 2.0.3 is deprecated. Am I launching it the wrong server executable, or are there plans to support a more recent version of Redis?

  • SocketAsyncEventArgs and buffering while messages are in parts

    - by Rob
    C# socket server, which has roughly 200 - 500 active connections, each one constantly sending messages to our server. About 70% of the time the messages are handled fine (in the correct order etc), however in the other 30% of cases we have jumbled up messages and things get screwed up. We should note that some clients send data in unicode and others in ASCII, so that's handled as well. Messages sent to the server are a variable length string which end in a char3, it's the char3 that we break on, other than that we keep receiving data. Could anyone shed any light on our ProcessReceive code and see what could possibly be causing us issues and how we can solve this small issue (here's hoping it's a small issue!) Code below:

  • What would make offsetParent null?

    - by Brian Ramsay
    I am trying to do positioning in JavaScript. I am using a cumulative position function based on the classic quirksmode function that sums offsetTop and offsetLeft for each offsetParent until the top node. However, I am running into an issue where the element I'm interested in has no offsetParent in Firefox. In IE offsetParent exists, but offsetTop and offsetLeft all sum up to 0, so it has the same problem in effect as in Firefox. What would cause an element that is clearly visible and usable on the screen to not have an offsetParent? Or, more practically, how can I find the position of this element in order to place a drop-down beneath it?

  • How do I filter one of the columns in a SQL Server SQL Query

    - by Kent S. Clarkson
    I have a table (that relates to a number of other tables) where I would like to filter ONE of the columns (RequesterID) - that column will be a combobox where only people that are not sales people should be selectable. Here is the "unfiltered" query, lets call it QUERY 1: SELECT RequestsID, RequesterID, ProductsID FROM dbo.Requests If using a separate query, lets call it QUERY 2, to filter RequesterID (which is a People related column, connected to People.PeopleID), it would look like this: SELECT People.PeopleID FROM People INNER JOIN Roles ON People.RolesID = Roles.RolesID INNER JOIN Requests ON People.PeopleID = Requests.RequesterID WHERE (Roles.Role <> N'SalesGuy') ORDER BY Requests.RequestsID Now, is there a way of "merging" the QUERY 2 into QUERY 1? (dbo.Requests in QUERY 1 has RequesterID populated as a Foreign Key from dbo.People, so no problem there... The connections are all right, just not know how to write the SQL query!)

  • Web-based document merge solution?

    - by rugcutter
    We are looking for a web-based document merge solution. Our application is a web-based project management tool built using Xataface - PHP on Windows IIS + mySQL. We have a function that allows the user to generate a status report in Microsoft Word format based on data in the tool. Currently this function is implemented using LiveDocX. We have a status report template, and LiveDocX performs the merge into the template using data from our project management tool. The main drawback is LiveDocx is web-service based. We are looking to replace LiveDocX in order to reduce our dependence on the up-time of a third-party web-service that we cannot control. Does anyone have any suggestions on a web based document merge solution that I can install on my IIS or PHP based server?

  • How to correctly load 32-bit DLL dependencies when running a program from a batch file

    - by neilwhitaker1
    I have written a tool that references Microsoft.TeamFoundation.VersionControl.Client.dll, which is a 32-bit DLL. When I build my tool on 64-bit Windows, I set Visual Studio to specifically target X86 in order to force it to a 32-bit build. Targetting X86 instead of All-CPU's prevents me from getting a BadImageFormatException, as long as I invoke the tool directly (e.g. by typing "myTool.exe" on the command line). However, if I run a batch file that invokes the tool, I still get the exception. This happens even if the batch file runs in a 32-bit command prompt (%WINDIR%\SysWOW64\cmd.exe). What else can I do to make this work?

  • Application leaking Strings?

    - by Jörg B.
    My .net application does some heavy string loading/manipulation and unfortunately the memory consumption keeps rising and rising and when looking at it with a profiler I see alot of unreleased string instances. Now at one point of time or another I do need all objects t hat do have these string fields, but once done, I could get rid of e.g. the half of it and I Dispose() and set the instances to null, but the Garbage Collector does not to pick that up.. they remain in memory (even after half an hour after disposing etc). Now how do I get properly rid of unneeded strings/object instances in order to release them? They are nowhere referenced anymore (afaik) but e.g. aspose's memory profiler says their distance to the gc's root is '3'?

  • Hos to group the complex list objects by using Linq

    - by Daoming Yang
    I want to select and group the products, and rank them by the number of times they occur. For example, I have an OrderList each of order object has a OrderProductVariantList(OrderLineList), and each of OrderProductVariant object has ProductVariant, and then the ProductVariant object will have a Product object which contains product information. A friend helped me with the following code. It could be compiled, but it did not return any value/result. I used the watch window for the query and it gave me "The name 'query' does not exist in the current context". Can anyone help me? Many thanks. var query = orderList.SelectMany( o => o.OrderLineList ) // results in IEnumerable<OrderProductVariant> .Select( opv => opv.ProductVariant ) .Select( pv => p.Product ) .GroupBy( p => p ) .Select( g => new { Product = g.Key, Count = g.Count() });

  • Fullscreen HTML Element using window.innerHeight/Width different with DOCTYPE

    - by CryptoQuick
    I'm trying to make an HTML5 canvas element fullscreen with the window.innerHeight and innerWidth properties. Unfortunately, on Chrome 10, when I set use the following doctype: <!DOCTYPE HTML> ...there is some extra scrolling space indicated by scroll bars which shouldn't appear. Without a doctype, everything is fine. The element is an HTML5 canvas, so styling with 100% will only stretch the content. Is it worth using a doctype which breaks my functionality (without which might be bad?), or should I subtract, say, 15px from the values in order to keep scroll bars from appearing? (which is kludgy)

  • What should be done first: Code reviews or Unit tests?

    - by goldenmean
    Hello, If a developer implements code for some module and wants to get it reviewed. What should be the order : *First unit test the module after designing test cases for the module, debugging and fixing the bugs and then give the modified code for peer code review (Pros- Code to be reviewed is 'clean' to a good extent. Reduces some avoidable review comments and rework. Cons- Developer might spend large time debugging/fixing a bug which could have pointed/anticipated in peer code reviews) Or *First do the code review with peers and then go for unit testing. What are your thoughts/experience on this? I believe this approach for unit testing, code reviewing should be programming language agnostic, but it would be interesting to know otherwise(if applicable) with specific examples. -AD

  • How do I create a downscaled copy of an FBO in OpenGL?

    - by Jasper Bekkers
    Hi, In order to speed up some post-processing shaders I'm using, I need to perform these operations on a framebuffer that is smaller in size than the actual window (about 1/4th or more). Most of the effects I want to optimize are simple blurring operations that could be replaced (for a large part) by smaller kernel and bilinear filtering. Thus, I need to create a copy of the current FBO into another one. However, I couldn't find anything, that works, on how to do this. I've tried using glBlitframebufferEXT and rendering a fullscreen quad into the other framebuffer, but both paths result in a black texture as output. How do I go about solving this problem?

  • help with exception handling in linq

    I have the following code to retrieve customer name, total (orders ), sum (order details) for reach customer in Northwind database. The problem with below code is that it raises an exception since a few customers dont have any entry in orders table. I know using the query syntax (join) the exception can be avoided. I want to know if the same can be handled with the extension method syntax. CustomerOrderDataContext db = new CustomerOrderDataContext(); var customerOrders = db.Customers.Select(c => new { CompanyName = c.CompanyName, TotalOrders = c.Orders.Count(), TotalQuantity = c.Orders.SelectMany(o => o.Order_Details).Sum(o=>o.Quantity) });

  • Cloning a private Github repo

    - by Solomon
    Hi, I have a private repository on Github for a project I'm working on. Until now I had only worked on my home desktop, but I just bought a laptop, and am trying to set it up so that I can work on the project from either computer, and push / pull changes. I added a new SSH key to my Github account for the laptop, and was successful in cloning and making changes to a public test repo that I set up. However, I couldn't clone the private repo. Is there anything special I need to do in the command line in order to clone a private repo? Do I need to set up a new GitHub account for my laptop and set myself up as a collaborator? Thanks for the help!

  • Is it possible to partition more than one way at a time in SQL Server?

    - by meeting_overload
    I'm considering various ways to partition my data in SQL Server. One approach I'm looking at is to partition a particular huge table into 8 partitions, then within each of these partitions to partition on a different partition column. Is this even possible in SQL Server, or am I limited to definining one parition column+function+scheme per table? I'm interested in the more general answer, but this strategy is one I'm considering for Distributed Partitioned View, where I'd partition the data under the first scheme using DPV to distribute the huge amount of data over 8 machines, and then on each machine partition that portion of the full table on another parition key in order to be able to drop (for example) sub-paritions as required.

  • Can you automatically create a mysqldump file that doesn't enforce foreign key constraints?

    - by Tai Squared
    When I run a mysqldump command on my database and then try to import it, it fails as it attempts to create the tables alphabetically, even though they may have a foreign key that references a table later in the file. There doesn't appear to be anything in the documentation and I've found answers like this that say to update the file after it's created to include: set FOREIGN_KEY_CHECKS = 0; ...original mysqldump file contents... set FOREIGN_KEY_CHECKS = 1; Is there no way to automatically set those lines or export the tables in the necessary order (without having to manually specify all table names as that can be tedious and error prone)? I could wrap those lines in a script, but was wondering if there is an easy way to ensure I can dump a file and then import it without manually updating it.
