  • Rails: Routing to a different controller based on request format

    - by Jimmy Cuadra
    I'm writing an app where I want all requests for HTML to be handled by the same controller action. I have some other routes that are JSON-specific. Here's what my routes look like: Blog::Application.routes.draw do constraints format: :json do resources :posts end match "(*path)" => "web#index" end The problem is that constraints is being interpreted as "this route only works with the specified format" rather than "skip this route and try the next one if the request is not in the specified format." In other words, navigating to /posts in the browser gives me a 406 Not Acceptable because the URL is constrained to the JSON format. Instead, I want it to fall through to web#index if the request is for HTML, and hit the resourceful route if the request is for JSON. How can this be achieved? (Using Rails 3.2.9.)

  • Merge a hash with the key/values of a string in ruby

    - by LazyJason
    Hi there, I'm trying to merge a hash with the key/values of string in ruby. i.e. h = {:day => 4, :month => 8, :year => 2010} s = "/my/crazy/url/:day/:month/:year" puts s.interpolate(h) All I've found is to iterate the keys and replace the values. But I'm not sure if there's a better way doing this? :) class String  def interpolate(e)    self if e.each{|k, v| self.gsub!(":#{k}", "#{v}")}  end end Thanks

  • Anonymous functions in C#

    - by Maxim Gershkovich
    The following syntax is valid VB.NET code Dim myCollection As New List(Of Stock) myCollection.Add(New Stock(Guid.NewGuid, "Item1")) myCollection.Add(New Stock(Guid.NewGuid, "Item2")) Dim res As List(Of Stock) = myCollection.FindAll(Function(stock As Stock) As Boolean If stock.Description = "Item2" Then Return True End If Return False End Function) How can I accomplish the same thing in C#? I have tried... myCollection.FindAll(bool delegate(Stock stock) { if (blah blah) { } }); But it appears I have somehow structured it incorrectly as I get the following error. "Error 1 Invalid expression term 'bool'"

  • Linq to SQL Strange SQL Translation

    - by Master Morality
    I have a simple query that is generating some odd SQL translations, which is blowing up my code when the object is saturated. from x in DataContext.MyEntities select new { IsTypeCDA = x.EntityType == "CDA" //x.EntityType is a string and EntityType.CDA is a const string... } I would expect this query should translate to: SELECT (CASE WHEN [t0].[EntityType] = @p1 THEN 1 ELSE 0 END) as [IsTypeCDA] ... Instead I get this : SELECT (CASE WHEN @p1 = [t0].[EntityType] THEN 1 WHEN NOT (@p1 = [t0].[EntityType]) THEN 0 ELSE NULL END) AS [IsTypeCDA] ... Since I'm saturating a POCO where IsTypeCDA is a bool, it blows up stating I can't assign null to bool. Any thoughts? Edit: fixed the property names so they make sense...

  • How to prevent UI from freezing during lengthy process?

    - by OverTheRainbow
    Hello, I need to write a VB.Net 2008 applet to go through all the fixed-drives looking for some files. If I put the code in ButtonClick(), the UI freezes until the code is done: Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click 'TODO Find way to avoid freezing UI while scanning fixed drives Dim drive As DriveInfo Dim filelist As Collections.ObjectModel.ReadOnlyCollection(Of String) Dim filepath As String For Each drive In DriveInfo.GetDrives() If drive.DriveType = DriveType.Fixed Then filelist = My.Computer.FileSystem.GetFiles(drive.ToString, FileIO.SearchOption.SearchAllSubDirectories, "MyFiles.*") For Each filepath In filelist 'Do stuff Next filepath End If Next drive End Sub Google returned information on a BackGroundWorker control: Is this the right/way to solve this issue? If not, what solution would you recommend, possibly with a really simple example? FWIW, I read that Application.DoEvents() is a left-over from VBClassic and should be avoided. Thank you.

  • Rails streaming file download

    - by Leonard Teo
    I'm trying to implement a file download with Rails. I want to eventually migrate this code to using S3 to serve the file. I've copied the Rails send_file code almost verbatim and I cannot seem to get it to stream a file to the user. What happens is that it sends 'a' file to the user, but the downloaded file itself simply contains the text.inspect of the Proc: # What am I doing wrong here? options = {} options[:length] = File.size(file.path) options[:filename] = File.basename(file.path) send_file_headers! options render :status => 200, :text => Proc.new { |response, output| len = 4096 File.open(file.path, 'rb') do |fh| while buf = fh.read(len) output.write(buf) end end } Ps: I've read in a number of other posts that it's not advisable to send files through the Rails stack, and if possible serve using the web server, or in the case of S3 use the hashed URL it can provide. Yes, we really do want to serve the file through the Rails stack.

  • Ruby on Rails: restrict file type with Paperclip using a flash uploader

    - by aperture
    I have a pretty basic Paperclip Upload model that is attached to a User model through has_many, and am using Uploadify to do the actual uploading. Flash sends all files with the content type of "application/octet-stream" so using validates_attachment_content_type rejects all files. In my create action, I am able to get the mime-type from the original file name, but only after it's been saved, with: def coerce(params) h = Hash.new h[:upload] = Hash.new h[:upload][:attachment].content_type = MIME::Types.type_for(h[:upload][:attachment].original_filename).to_s ... end and def create diff_params = coerce(params) @upload = Upload.new(diff_params[:upload]) ... end What would be the best way of white listing file types? I am thinking a before_validation method, but I'm not sure how that would work. Any ideas would be welcome.

  • Interacting With Class Objects in Ruby

    - by michaelmichael
    How can I interact with objects I've created based on their given attributes in Ruby? To give some context, I'm parsing a text file that might have several hundred entries like the following: ASIN: B00137RNIQ -------------------------Status Info------------------------- Upload created: 2010-04-09 09:33:45 Upload state: Imported Upload state id: 3 I can parse the above with regular expressions and use the data to create new objects in a "Product" class: class Product attr_reader :asin, :creation_date, :upload_state, :upload_state_id def initialize(asin, creation_date, upload_state, upload_state_id) @asin = asin @creation_date = creation_date @upload_state = upload_state @upload_state_id = upload_state_id end end After parsing, the raw text from above will be stored in an object that look like this: [#<Product:0x00000101006ef8 @asin="B00137RNIQ", @creation_date="2010-04-09 09:33:45 ", @upload_state="Imported ", @upload_state_id="3">] How can I then interact with the newly created class objects? For example, how might I pull all the creation dates for objects with an upload_state_id of 3? I get the feeling I'm going to have to write class methods, but I'm a bit stuck on where to start.

  • Ruby/Rails - Add records to an object with each loop iteration / Object vs Arrays

    - by ChrisWesAllen
    I'm trying to figure out how to add records to an existing object for each iteration of a loop. I'm having a hard time discovering the difference between an object and an array. I have this @events = Event.find(1) @loops = Choices.find(:all, :limit => 5) #so loop for 5 instances of choice model for loop in @loops @events = Event.find(:all,:conditions => ["event.id = ?", loop.event_id ]) end I'm trying to add a new events to the existing @events object based on the id of whatever the loop variable is. But the ( = ) operator just creates a new instance of the @events object. I tried ( += ) and ( << ) as operators but got the error "You have a nil object when you didn't expect it! You might have expected an instance of Array. The error occurred while evaluating nil" I tried created an array events = [] events << Event.find(1) @loops = Choices.find(:all, :limit => 5) #so loop for 5 instances of choice model for loop in @loops events << Event.find(:all,:conditions => ["event.id = ?", loop.event_id ]) end But I dont know how to call that arrays attributes within the view With objects I was able do create a loop within the view and call all the attributes of that object as well... <table> <% for event in @events %> <tr> <td><%= link_to event.title, event %></td> <td><%= event.start_date %></td> <td><%= event.price %></td> </tr> <% end %> </table> How could i do this with an array set? So the questions are 1) Whats the difference between arrays and objects? 2) Is there a way to add into the existing object for each iteration? 3) If I use an array, is there a way to call the attributes for each array record within the view?

  • In Vim, what is the best way to select, delete, or comment out large portions of multi-screen text?

    - by Edward Tanguay
    Selecting a large amount of text that extends over many screens in an IDE like Eclipse is fairly easy since you can use the mouse, but what is the best way to e.g. select and delete multiscreen blocks of text or write e.g. three large methods out to another file and then delete them for testing purposes in Vim when using it via putty/ssh where you cannot use the mouse? I can easily yank-to-the-end-of-line or yank-to-the-end-of-code-block but if the text extends over many screens, or has lots of blank lines in it, I feel like my hands are tied in Vim. Any solutions? And a related question: is there a way to somehow select 40 lines, and then comment them all out (with "#" or "//"), as is common in most IDEs?

  • Anonymous method as function result

    - by iamjoosy
    What I want to do is to assign an anonymous method which I get as a function result to a variable of the same type. Delphi complains about not beeing able to do the assignement. Obviously Delphi things I want to assign the "GetListener" function instead of the result of that same function. Any help with this is very much appreciated. type TPropertyChangedListener = reference to procedure (Sender: TStimulus); TMyClass = class function GetListener:TPropertyChangedListener end; .... var MyClass: TMyClass; Listener: TPropertyChangedListener; begin MyClass:= TMyClass.create; Listener:= MyClass.GetListener; // Delphi compile error: E2010 Incompatible types: TPropertyChangedListener' and 'Procedure of object' end;

  • Empty Structures compile in VB 10+

    - by Mark Hurd
    This is at least a documentation error, if not a bug. In VB.NET prior to .NET 4.0 (i.e. VB.NET 7 through 9) an empty Structure declaration fails at compile-time with error BC30281: Structure 'MySimpleEmpty' must contain at least one instance member variable or Event declaration. E.g. The following two structures compile successfully in VB10, and not prior: Structure MySimpleEmpty End Structure Public Structure AnotherEmpty Public Const StillEmpty As Boolean = True End Structure I note the documentation for the Error BC30281 stops at VB9, but the documentation for the Structure statement still has the datamemberdeclarations as required even as of VB11 (.NET 4.5 VS2012). These two Structures compile in VB11 (VS2012) as well. (Thanks John Woo.) Is there some blog entry or documentation confirming this is an intended change or a bug in VB10 and later?

  • Perl, deleting an .xml file created and open with IO::File and XML::Writer?

    - by Sho Minamimoto
    So I'm running through a list of things and have code that creates an .xml file with IO::File called $doc, then I make a new writer with XML::Writer(OUTPUT = $doc). More code runs and I build a big xml file with XML::Writer. Then, near the end of the file, I find out if I need this file at all. If I do need it, I just $writer-end(); $doc-close(); but if I don't need it, what should I enter to just delete all data I've stored/saved and move onto the next file? I tried unlink($docpath) (before and after $doc-close()), the file was not deleted.

  • What are some useful SQL statements / usage patterns that should be known by all developers who may

    - by Jian Lin
    What are some useful SQL statements that should be known by all developers who may touch the Back end side of the project? (Update: just like in algorithm, we know there are sorting problems, shuffling problems, and we know some solutions to them. This question is aiming at the same thing). For example, ones I can think of are: Get a list of Employees and their boss. Or one with the employee's salary greater than the boss. (Self-join) Get a list of the most popular Classes registered by students, from the greatest number to the smallest. (Count, group by, order by) Get a list of Classes that are not registered by any students. (Outer join and check whether the match is NULL, or by Get from Classes table, all ClassIDs which are NOT IN (a subquery to get all ClassIDs from the Registrations table)) Are there some SQL statements that should be under the sleeve of all developers that might touch back end data?

  • Better product to develop for, iPad or Android based tablet in a purely business related application

    - by Caylem
    Hey guys Just wondering what you'd suggest as the best platform for developing a business application for a tablet device. The application needs to be multitouch, have access to a maps API, a database on the device. It will not be going on sale in the app store or Androids market, it is purely for specific business task and not for the general consumer. Obviously the options seem to be iPhone OS and the iPad or Android and an Android tablet device. The form factor for the end product requires something in the region of 8 inch+ screen and enough processing power to provide a good experience for the end user. Any help would be much appreciated. Thanks

  • Rails 3 ActiveModel Nested Class I18n

    - by Dave
    Given the following class definition in ruby: class Conversation class Message include ActiveModel::Validations attr_accessor :quantity validates :quantity, :presence => true end end How can you use i18n to customize to error message. For example the correct lookup for the class Conversation would be activemodel: errors: models: conversation: attributes: quantity: blank: "Some custom message" But what is it for the Message class? I tried: activemodel: errors: models: conversation: message: attributes: quantity: blank: "Some custom message" activemodel: errors: models: message: attributes: quantity: blank: "Some custom message" activemodel: errors: models: conversation::message: attributes: quantity: blank: "Some custom message" None of them work Any ideas or is this a bug with ActiveModel or I18n?

  • oracle display for every stored procedure the execution time

    - by CC
    Hi all. I'm working on a stored procedure. Inside this one, there are many call to the other stored procedures. There are a bunch of them. I was wondering if there is a option to be able to have the execution time of every stored procedure involved, every function (with a start and end time, ior something like that). The idea is that I need to optimise it and I should touch every part, and since I not sure where is the longest execution time, is a bit difficult. And after a modification I would like the see the hole process if it's shorter or not. If I call the procedure from unix, using sql plus, I have no log. If I call it from TOAD, it's blocked until the end. Any idea? I'm not a dba, so I don't have many rights on the database, I'm just a regular user. Thanks for any advice. C.C.

  • How do I find the user that has both a cat and a dog?

    - by brad
    I want to do a search across 2 tables that have a many-to-one relationship, eg class User << ActiveRecord::Base has_many :pets end class Pet << ActiveRecord::Base belongs_to :users end Now let's say I have some data like so users id name 1 Bob 2 Joe 3 Brian pets id user_id animal 1 1 cat 2 1 dog 3 2 cat 4 3 dog What I want to do is create an active record query that will return a user that has both a cat and a dog (i.e. user 1 - Bob). My attempt at this so far is User.joins(:pets).where('pets.animal = ? AND pets.animal = ?','dog','cat') Now I understand why this doesn't work - it's looking for a pet that is both a dog and a cat so returns nothing. I don't know how to modify this to give me the answer I want however. Does anyone have any suggestions? This seems like it should be easy - it doesn't seem like an especially unusual situation.

  • Separating an Array into a comma seperated string with quotes

    - by user548744
    I'm manually building an SQL query where I'm using an Array in the params hash for an SQL IN statement, like: ("WHERE my_field IN('blue','green','red')"). So I need to take the contents of the array and output them into a string where each element is single quoted and comma seperated (and with no ending comma). So if the array was: my_array = ['blue','green','red'] I'd need a string that looked like: "'blue','green','red'" I'm pretty new to Ruby/Rails but came up with something that worked: if !params[:colors].nil? @categories_array = params[:colors][:categories] @categories_string ="" for x in @categories_array @categories_string += "'" + x + "'," end @categories_string.chop! #remove the last comma end So, I'm good but curious as to what a proper and more consise way of doing this would look like? Thanks
