  • Monkeypatch a model in a rake task to use a method provided by a plugin?

    - by gduquesnay.mp
    During some recent refactoring we changed how our user avatars are stored not realizing that once deployed it would affect all the existing users. So now I'm trying to write a rake task to fix this by doing something like this. namespace :fix do desc "Create associated ImageAttachment using data in the Users photo fields" task :user_avatars => :environment do class User # Paperclip has_attached_file :photo ... <paperclip stuff, styles etc> end User.all.each do |user| i = ImageAttachment.new i.photo_url = user.photo.url user.image_attachments << i end end end When I try running that though I'm getting undefined method `has_attached_file' for User:Class I'm able to do this in script/console but it seems like it can't find the paperclip plugin's methods from a rake task.

  • Lua : Dynamically calling a function with arguments.

    - by Tipx
    Using Lua, I'm trying to dynamically call a function with parameters. I want to send a string to be parsed in a way that: 1st argument is a class instance "Handle" 2nd is the function to be called All that is left are arguments "modules" is a a table like { string=<instance of a class> } split() is a simple parser that returns a table with indexed strings. function Dynamic(msg) local args = split(msg, " ") module = args[1] table.remove(args, 1) if module then module = modules[module] command = args[1] table.remove(args, 1) if command then if not args then module[command]() else module[command](unpack(args)) -- Reference 1 end else -- Function doesnt exist end else -- Module doesnt exist end end When I try this with "ignore remove bob", by "Reference 1", it tries to call "remove" on the instance associated with "ignore" in modules, and gives the argument "bob", contained in a table (with a single value). However, on the other side of the call, the remove function does not receive the argument. I even tried to replace the "Reference 1" line with module[command]("bob") but I get the same result.

  • LINQ to SQL - Why can't you use a WHERE after an ORDER BY?

    - by MCS
    The following code: // select all orders var orders = from o in FoodOrders where o.STATUS = 1 order by o.ORDER_DATE descending select o; // if customer id is specified, only select orders from specific customer if (customerID!=null) { orders = orders.Where(o => customerID.Equals(o.CUSTOMER_ID)); } gives me the following error: Cannot implicitly convert type 'System.Linq.IQueryable' to 'System.Linq.IOrderedQueryable'. An explicit conversion exists (are you missing a cast?) I fixed the error by doing the sorting at the end: // select all orders var orders = from o in FoodOrders where o.STATUS = 1 select o; // if customer id is specified, only select orders from specific customer if (customerID!=null) { orders = orders.Where(o => customerID.Equals(o.CUSTOMER_ID)); } // I'm forced to do the ordering here orders = orders.OrderBy(o => o.ORDER_DATE).Reverse(); But I'm wondering why is this limitation in place? What's the reason the API was designed in such a way that you can't add a where constraint after using an order by operator?

  • Is looping through the entityreference the correct way?

    - by Jova
    I want to get all users that have a specific role to a list of usernames. Is using .Include to include all the users, and going through the UsersReference the best way to loop through all the users that are associated with the role? I noticed I could not do a foreach(User user in role.Users) but UsersReference seem to work, but is that how it's supposed to be done? Going through the reference? using (var context = new MyEntities()) { List<string> users = new List<string>(); Role role = (from r in context.Roles.Include("Users") where r.RoleName == roleName select r).FirstOrDefault(); foreach (User user in role.UsersReference) users.Add(user.UserName); return users.ToArray(); }

  • Recommended way to remove events on destroy with jQuery UI Widget Factory

    - by user1031947
    I'm using the jQuery UI Widget Factory to build a jQuery plugin. My plugin binds custom events to the window... _subscribe: function() { $(window).on("dragger.started", function() { ... }); } I am wondering how to go about removing these events, when a particular instance of the plugin is destroyed. If I use... destroy: function() { $(window).off("dragger.started"); } ...then that will mess up any other instances of the plugin on the page, as it will remove all "dragger.started" events. What is the recommended way to go about destroying only those events that are associated with an instance of the plugin? Thanks (in advance) for your help.

    - by Billy Logan
    Hello everyone, I have a linq query that populates a list of designers. since i am using the filters below my sorting is not functioning properly. My question is with the given code below how can i best sort this List after the fact or sort while querying? I have tried to sort the list after the fact using the following script but i receive a compiler error: List<TBLDESIGNER> designers = new List<TBLDESIGNER>(); designers = 'calls my procedure below and comes back with an unsorted list of designers' designers.Sort((x, y) => string.Compare(x.FIRST_NAME, y.LAST_NAME)); Query goes as follows: List<TBLDESIGNER> designer = null; using (SOAE strikeOffContext = new SOAE()) { //Invoke the query designer = AdminDelegates.selectDesignerDesigns.Invoke(strikeOffContext).ByActive(active).ByAdmin(admin).ToList(); } Delegate: public static Func<SOAE, IQueryable<TBLDESIGNER>> selectDesignerDesigns = CompiledQuery.Compile<SOAE, IQueryable<TBLDESIGNER>>( (designer) => from c in designer.TBLDESIGNER.Include("TBLDESIGN") orderby c.FIRST_NAME ascending select c); Filter ByActive: public static IQueryable<TBLDESIGNER> ByActive(this IQueryable<TBLDESIGNER> qry, bool active) { //Return the filtered IQueryable object return from c in qry where c.ACTIVE == active select c; } Filter ByAdmin: public static IQueryable<TBLDESIGNER> ByAdmin(this IQueryable<TBLDESIGNER> qry, bool admin) { //Return the filtered IQueryable object return from c in qry where c.SITE_ADMIN == admin select c; } Thanks in advance, Billy

  • Iphone contact photo

    - by Kiran
    I tried to search an answer for this but couldn't find one. My iPhone application needs to access the Photo associated with the contact in the phonebook. However, it also needs to make sure that every time application is launched, it verifies that the photo is the same. So, in essence, I am trying to access the photo used by contacts database for a person's phone number or email address. - Is there a way for me to do this? Any help is appreciated.

  • 2 Column Array in SAP ABAP A = 1, B = 2... ZZZ = ?

    - by Techboy
    I need to create a 2 column array in ABAP so that a program can look up a record item (defined by the letters A - ZZZ) and then return the number associated with it. For example: A = 1 B = 2 C = 3 ... Z = 26 AA = 27 AB = 28 ... AZ = BA = ... BZ = CA = ... ... ZZZ = Please can you suggest how I can code this. Is there a better option than writing an array? Thanks.

  • Equivalent of describeType for Flex Component EVENTS

    - by Joshua
    Using "introspection" In Flex I can say: var classInfo:XML=describeType(SomeObject); Which will list for me the Accessors, Methods And Variables. (http://livedocs.adobe.com/flex/3/html/help.html?content=usingas_8.html) But what is the equivalent to programmatically inspect all of an object's possible EVENTS? (NOT JUST the events for which event listeners have been set, but to somehow step through a list of all VALID EVENTS for which event listeners may POTENTIALLY be set -- I realize that such lists are readily available online, and that's great for cases when I know the object's type at design type, but I require some way to inspect any given displayobject programmatically at runtime, and determine what events, if any, are or may be associated with it.)

  • Convert jpg Byte[] to Texture2D

    - by Damien Sawyer
    I need to import jpeg images into a WP7/XNA app with associated metadata. The program which manages these images exports to an XML file with an encoded byte[] of the jpg files. I've written a custom importer/processor which successfully imports the reserialized objects into my XNA project. My question is, given the byte[] of the jpg, what is the best way to convert it back to Texture2D. // 'Standard' method for importing image Texture2D texture1 = Content.Load<Texture2D>("artwork"); // Uses the standard Content processor "Texture - XNA Framework" to import an image. // 'Custom' method var myCustomObject = Content.Load<CompiledBNBImage>("gamedata"); // Uses my custom content Processor to return POCO "CompiledBNBImage" byte[] myJPEGByteArray = myCustomObject.Image; // byte[] of jpeg Texture2D texture2 = ???? // What is the best way to convert myJPEGByteArray to a Texture2D? Thanks very much for your help. :-) DS

  • How to color HTML elements based on a user command string

    - by Anonymous the Great
    When you type something like "red:Hi:" it will type "Hi" in red. The following script does not work and I do not know why, (The one who made the sorting PHP function is Graphain, thanks again!) <?php function getit($raw) { # If the value was posted $raw = isset($raw) ? $raw : ""; # Split it based on ':' $parsed = explode(':', $raw); $colorClass = ""; $text = ""; if (count($parsed) >= 2) { $colorClass = $parsed[0]; $text = $parsed[1]; $text = "~~~" . $text . "~~~" . $colorClass; return $text; } } ?> <script type="text/javascript"> function postit() { var preview = document.getElementById("preview").value; var submit = document.getElementById("post").value; var text = <?php getit(submit); ?> var t = text[0]; preview = t; } </script> <textarea id="preview" cols=70 rows=5 readonly>Preview box</textarea> <p> <textarea id="post" cols=70 rows=5/>Submit box</textarea> <p> <input type="button" onclick="postit();" value="Submit"/>

  • How can I create a new email account in Java?

    - by Jeremy Goodell
    I am able to send and receive emails from my JSPs and associated Java code using the Java Mail API (javax.mail.*). Now I would like to create a new POP3 email account programmatically when a user registers for my site. I've found surprisingly little information about this with web searches. I would think it would be a somewhat common problem. It appears that the Java Mail API does not provide any assistance in this area. I have many email accounts available under my godaddy account, and to manually create an account, I just go to the godaddy email control panel, click Add, and specify the email address and password. This is exactly what I would like to do via a Java program. Any ideas?

  • Changing the config file in a Visual Studio Package

    - by Andrei
    Hello everybody. I'm building a Visual Studio Package and associated with it, I have an app.config file (which contains some information about connecting to a WCF service). As far as I can tell, this package is actually connecting to the devnev.exe.config configuration file (if I use AppDomain.CurrentDomain.SetupInformation.ConfigurationFile), it will retrieve the path to the devnev.exe.config Firstly, is this correct? Shouldn't the package automatically pick up the app.config file? If this is the case, then how can I make the project use the app.config file? I'm running VS2010 Ultimate, programming in C#. Thanks!

  • Setting a Forms Authentication cookie from a .NET client application

    - by Jon DellOro
    We currently have a .NET 2.0 web app that uses forms authentication via cookies. Associated with this web app is an old VB6 client application that has its own login system. Currently, the users have to login to the VB6 app, and then when they click on a link, need to authenticate themselves again with the .NET forms authentication system. I'm wondering if it's possible to create a client side .NET application, give it the username and password, and set the forms authentication cookie (without the browser being opened). Is that possible??

  • Database: storing data from user registration form

    - by teggy
    Let's say I have an user registration form. In this form, I have the option for the user to upload a photo. I have an User table and Photo table. My User table has a "PathToPhoto" column. My question is how do I fill in the "PathToPhoto" column if the photo is uploaded and inserted into Photo table before the user is created? Another way to phrase my question is how to get the newly uploaded photo to be associated to the user that may or may not be created next. I'm using python and postgresql.

  • Single HTML Table from multiple MySQL tables

    - by David Chouinard
    Hi! I've been struggling for a while with this one; I'll try to explain it here as simply as possible. Consider this MySQL table: +----------+-----------+---------+--------+ |status_id |session_id |pilot_id |present | +----------+-----------+---------+--------+ |1 |61 |901 |1 | |2 |63 |901 |1 | |3 |62 |901 |0 | |4 |62 |902 |1 | |5 |63 |903 |1 | +----------+-----------+---------+--------+ Both session_id and pilot_id are foreign keys making reference to a primary key in another table. The same pilot_id can be associated with different session_id, but every pilot_id-session_id combination is unique. I need to make an HTML table (in PHP) that would display the data like this: +----------+---------+---------+---------+ | |61 |62 |63 | +----------+---------+---------+---------+ |901 |X | |X | |902 | |X | | |903 | | |X | +----------+---------+---------+---------+ Hence, rows are pilot_id and columns are session_id. When a pilot_id-session_id combination has a present value of 1, the corresponding cell should be checked. (ie. when the row-combination is zero or the combination does not exist in the MySQL table, nothing should appear in the HTML table) Phew. Any ideas? Thanks!

  • load animationImage from a table view Controller

    - by ackoverflow
    I use a UITableViewController to display a list of items, and one of the items selection must lead to a photo gallery created with animationImages. I usually declare the controllers associated to the first level selection with something like : MyController *myController = [[MyController alloc] initWithStyle:UITableViewStylePlain]; myController.title = @"title 1"; myController.rowImage = [UIImage imageNamed:@"myControllerIcon.png"]; .. But I believe a UIViewController is needed to use animationImages.. How can I display a image animation directly from a table view ?

  • What 'best practices' exist for handing enum heirarchies?

    - by FerretallicA
    I'm curious as to any solutions out there for addressing enum heirarchies. I'm working through some docs on Entity Framework 4 and trying to apply it to a simple inventory tracking program. The possible types for inventory to fall into are as follows: INVENTORY ITEM TYPES: Hardware PC Desktop Server Laptop Accessory Input (keyboards, scanners etc) Output (monitors, printers etc) Storage (USB sticks, tape drives etc) Communication (network cards, routers etc) Software What recommendations are there for handling enums in a situation like this? Are enums even the solution? I don't really want to have a ridiculously normalised database for such a relatively simple experiment (eg tables for InventoryType, InventorySubtype, InventoryTypeToSubtype etc). I don't really want to over-complicate my data model with each subtype being inherited even though no additional properties or methods are included (except PC types which would ideally have associated accessories and software but that's probably out of scope here). It feels like there should be a really simple, elegant solution to this but I can't put my finger on it. Any assistance or input appreciated!

  • Intellij-Idea: Marking all files of unknown type be type: text (so that they are searchable)

    - by sixtyfootersdude
    Many of my scripts etc in intellij are marked with a question mark. Then when I click on them them it prompts me: The file "bla" cannot be associated with a registered file type. Please choose one: <insert table of file choices> This would not matter except the files are not searchable (with ctrl-shift-n) until they are marked as text. This is a major problem for me. I have an enormous code base and I don't want to mark all of the unknown files as text. Is there anyway that I can do that? *(Note: I have cross posted this to the intellij form

  • Clickonce program will not start when launched from shell_execute

    - by Brandon
    I have a very old program that I have no control over. It launches a filetype with its default application like this(I cannot modify this code): LET Err (SHELL_EXECUTE 'open' (FIX_MESG '"{1}"' File_name) '' '') ^^The above code works, so long as that filetype isn't associated with ClickOnce. The old program is 32 bit, the OS is Windows 7 64 bit. I can compile my clickonce program as anything, but none seem to work. (I've tried x84, x64 and anyCPU) How can I make a 32 bit program use shell execute to launch a ClickOnce program on a 64bit OS?

  • How can I get Dashcode to open JSP files?

    - by user332000
    A simple tools question but it's driving me nuts. I have some .jsp files on my computer that I associated with Dashcode, figuring it would be a suitable editor. But when I try to open the files, all I get is a dialog box that says, "Dashcode cannot open files of this type". I thought there'd be an easy way to fix this but I can't find it. Nowhere in Dashcode's preferences can I find any list of valid file extensions. I poked around its resources folder for a while and couldn't find it there either. The Dashcode menubar is visible when the error is up, so I'm guessing that this is Dashcode itself complaining that it cannot open this file rather than the OS preventing it from trying. How exactly does this work? Is Dashcode really just hard-coded to recognize only files of certain types by their file extension? Isn't there a way to change it? Thanks, Frank

  • Unreachable breakpoint at execut(able/ing) code

    - by shadeMe
    I've got two DLLs, one in written in native C++ and the other in C++/CLI. The former is injected into a process, and at a later point in time, loads the latter. While debugging, I noticed that the native DLL's breakpoints were functioning correctly while the other's weren't, even though its code was being executed. The breakpoints showed this message: This breakpoint will not be hit. No executable code associated with this line. Possible causes include: preprocessor directives or compiler/linker optimizations. The modules window tells me that the plugin's symbols are loaded. I'm running with its DEBUG build. Any ideas on why this is so and perhaps a fix ?

  • How do I generate different yyparse functions from lex/yacc for use in the same program?

    - by th
    Hi, I want to generate two separate parsing functions from lex/yacc. Normally yacc gives you a function yyparse() that you can call when you need to do some parsing, but I need to have several different yyparses each associated with different lexers and grammars. The man page seems to suggest the -p (prefix) flag, but this didn't work for me. I got errors from gcc that indicated that yylval was not properly being relabeled (i.e. it claims that several different tokens are not defined). Does anyone know the general rpocedure for generating these separate functions? thanks
