  • How do I pass objects through a _url based on a routing in rails?

    - by Angela
    I want to pass the attributes associated with two objects into a path created from a route. In this case, the _url is skip_contact_letter_url. contact_letter and letter are passed through a render partial. The clip below resides in the partial. <%= link_to_remote "Skip Letter Remote #{contact_letter}", :url => skip_contact_letter_url(contact_letter, letter), :update => "update-area-#{contact_letter.id}-#{letter.id}" %> <span id='update-area-<%="#{contact_letter.id}-#{letter.id}"%>'> </span> The route I created looks like this: map.resources :contact_letters, :member => {:skip => :post} And the controller looks like this: def skip @contact_letter = ContactLetter.new(params[:all]) @contact_letter.status = "skipped" @contact_letter.date_sent = Date.today #@contact_letter.date_created = Date.today if @contact_letter.save render :text => 'This letter was skipped!' end end When I look at the console, none of the parameters from contact_letter or letter get passed through.

  • POST a form from a .NET Application

    - by Marlon
    I'm not familiar with http stuff, but how would I be able to submit data to a website? There is a submit button that I would like to "press" from a console app. This is not my own website. This is part of the page source, not sure if it has any relevance: <form action="rate.php" method="post"> I looked at the HttpWebRequest class but I am unfamiliar with what properties I need to fill in. Sorry I'm so vague but I'm not familiar with http.

  • Python lxml - returns null list

    - by Chris Finlayson
    I cannot figure out what is wrong with the XPATH when trying to extract a value from a webpage table. The method seems correct as I can extract the page title and other attributes, but I cannot extract the third value, it always returns an empty list? from lxml import html import requests test_url = 'SC312226' page = ('https://www.opencompany.co.uk/company/'+test_url) print 'Now searching URL: '+page data = requests.get(page) tree = html.fromstring(data.text) print tree.xpath('//title/text()') # Get page title print tree.xpath('//a/@href') # Get href attribute of all links print tree.xpath('//*[@id="financial"]/table/tbody/tr/td[1]/table/tbody/tr[2]/td[1]/div[2]/text()') Unless i'm missing something, it would appear the XPATH is correct: Chrome screenshot I checked Chrome console, appears ok! So i'm at a loss $x ('//*[@id="financial"]/table/tbody/tr/td[1]/table/tbody/tr[2]/td[1]/div[2]/text()') [ "£432,272" ]

  • Active MQ showing more than one (ghost) consumer

    - by Shoey
    We have a system that uses ActiveMQ (Queues) - and have exactly one producer and one consumer (implemented as a Windows Service in .NET). Over the weekend, the infrastructure team had a reboot of the servers on the network, and from then on we noticed that there are more than one ghost consumer appearing that listens to the queue and we also suspect reads and deletes the messages. My questions are: is there any way from the Active MQ management console to find out what the consumers are (hostnames, etc). and Are there any scenarios in which inadvertent consumers get 'created'? For instance, there were suggestions about the active MQ journal folders getting corrupted after a reboot, or there is another suggestion that another machine with Active MQ broker automatically makes itself a consumer of all the queues on the main/live active mq server.

  • Worried about spiders repeatedly hitting high-demand page

    - by Matt Thrower
    Due to some rather bizarre architectural considerations I've had to set up something that really ought to run as a console application as a web page. It does the job of writing a large variety of text files and xml feeds from our site data for various other services to pick up so obviously it takes a little while to run and is pretty processor intensive. However, before I deploy it I'm rather worried that it might get hit repeatedly by spiders and the like. It's fine for the data to be re-written but continual hits on this page are going to trigger performance issues for obvious reasons. Is this something I ought to worry about? Or in reality is spider traffic unlikely to be intensive enough to cause problems?

    On load, the script is not un-checking the disabled checkboxes, I have tried everything. I have even tried running this code from Chrome Console, and it is working, but not in normal ways.

    - by ffc
    hi, I have a WCF service that i've been able to communicate with fine while it's hosted locally.

But when I try to run a Get() method on the service reference, it just hangs with no response. How can I begin to debug this? Thanks!

  • how do I download a large file (via HTTP) in .NET

    - by nickcartwright
    I need to download a LARGE file (2GB) over HTTP in a C# console app. Problem is, after about 1.2GB, the app runs out of memory. Here's the code I'm using: WebClient request = new WebClient(); request.Credentials = new NetworkCredential(username, password); byte[] fileData = request.DownloadData(baseURL + fName); As you can see... I'm reading the file directly into memory. I'm pretty sure I could solve this if I were to read the data back from HTTP in chunks and write it to a file on disk. Does anyone know how I could do this?

  • Print the next X number of lines in Scala

    - by soulesschild
    Trying to learn Scala using the Programming in Scala book and they have a very basic example for reading lines from a file. I'm trying to expand on it and read a file line by line, look for a certain phrase, then print the next 6 lines following that line if it finds the line. I can write the script easily enough in something like java or Perl but I have no idea how to do it in Scala (probably because I'm not very familiar with the language yet...) Here's the semi adapted sample code from the Programming in Scala book, import scala.io.Source if(args.length>0) { val lines = Source.fromFile(args(0)).getLines().toList for(line<-lines) { if(line.contains("secretPhrase")) { println(line) //How to get the next lines here? } } } else Console.err.println("Pleaseenterfilename")

  • New records added to DataGridView aren't displayed

    - by Ross
    I have a custom Order class, groups of which are stored in List<Order> and a DataGridView. I think the problem is in my implementation so here's how I'm using it: In the form enclosing DataGridView (as OrdersDataGrid): public partial class MainForm : Form { public static List<Order> Orders; public MainForm() { // code to populate Orders with values, otherwise sets Orders to new List<Order>(); OrdersDataGrid.DataSource = Orders; } Then in another form that adds an Order: // Save event public void Save(object sender, EventArgs e) { Order order = BuildOrder(); // method that constructs an order object from form data MainForm.Orders.Add(order); } From what I can tell from the console this is added successfully. I thought the DataGrid would be updated automatically after this since Orders has changed - is there something I'm missing? The DataGrid accepts the class since it generates columns from the members.

  • Discard unprintable characters returned in server's XML response

    - by Penang
    While trying to use the Bing API to search, I am getting characters that are not printable and do not seem to hold any extra information. The goal is to save the XML (UTF-8) response as a text file to be parsed later. My code currently looks something like this: URL url = new URL(queryURL); BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream())); BufferedWriter out = new BufferedWriter(new FileWriter(query+"-"+saveResultAs)); String str = in.readLine(); out.write(str); in.close(); out.close(); When I send the contents of 'str' to console it looks something like this: and here's a what the newly created local XML file looks like: What should I be doing to convert the UTF-8 text so that str does not have the extra characters?

  • send commands to a backgrounded jobs stdin

    - by dpcd
    I have a java server application that, when its running, you can interact with it sending commands via stdin. I want to write a web interface that can send these commands to it. In order to do that I need some way of getting commands from php to the stdin for this backgrounded job. Is there a way to do this from console? or possibly write some kind of wrapper that controls the server job and can access its stdin ? could this be done in python?

  • Why in the hell is this happening?

    - by user202411
    I just can't understand why is my database (mysql) behaving like this! My console shows that the record is created properly (please, notice the "remote_id" value): Tweet Create (0.3ms) INSERT INTO `tweets` (`remote_id`, `text`, `user_id`, `twitter_account_id`) VALUES (12325438258, 'jamaica', 1, 1) But when I check the record, it shows that the remote_id is 2147483647 intead of the provided value (12325438258 in the example above)... This table has many entries, but this field is always written with 2147483647... It was supposed to fill this space with an unique id (which I guarantee you is being generated properly).

  • Core Data - insertNewObjectForEntityForName debug

    - by Snow Crash
    I'm trying to figure out why insertNewObjectForEntityForName is not working. I assume it's something to do with my data model but can't be sure. Xcode does not report any errors nor does it crash. All I get is the first log statement output to the console. NSLog(@"Get here..."); Task *task = (Task *)[NSEntityDescription insertNewObjectForEntityForName:@"Task" inManagedObjectContext:insertionContext]; NSLog(@"but never get here..."); Any suggestions as to how I can work out what the problem is?

  • Objective-C why doesn't my array of array works?

    - by Quetsche
    This is probably a completely stupid question, but i'm pretty new at objective-C and programing in general. i'm trying to make an array of arrays but can't manage to make it work : @interface ArraysAndDicts : NSObject { NSMutableArray * mySimpleArray; NSMutableArray * myComplicatedArray; } the implementation : -(void)generateValueForArrayOfArrays { [self generateValueForArray]; //this generates an array with 5 elements 'mySimpleArray' [myComplicatedArray addObject:mySimpleArray]; NSMutableArray * mySecondaryArray = [[NSMutableArray alloc] init]; [mySecondaryArray addObject:@"twoone"]; [mySecondaryArray addObject:@"twotwo"]; [myComplicatedArray addObject:mySecondaryArray]; (i edited out all the NSLogs for clarity) When running my app, the console tells me : mySecondaryArray count = 2 mySimpleArray count = 5 myComplicatedArraycount = 0 So, i know there are other ways to make multidimensional arrays, but i'd really like to know why this doesn't work. Thank you.

  • how to view associated click function code

    - by llamerr
    For example, i associate following function with some element $('table#users tbody tr:first #save').click(function(){ $(this).closest('tr').remove(); }); Now, if i don't know where this function is stored, is there a way to view associated with click() code? In above example, i want a way to view that in firebug, or in another way $(this).closest('tr').remove(); If I'm writing in console following, i'm get a link to dom inspector >>> ($('table#users tbody tr:first #save').click) function() but link is for jquery library, not the code i want.

  • Can Silverlight be linked with a C++ static library ?

    - by Niklaos
    Hi, I'm currently doing research to start a new project. This project will be in 2 parts a light Client (probably console) and an heavy one using silverlight. The light client must be cross-platform. However, they will both use the same Core (by the way, the core will need to use the sockets). I'd like to use C++ to build the light client but given that the core is common to both applications, it would be much appreciated if it's could be the same code. So the question is quite simple : Can Silverlight be compilated with a C++ static library ? And if it's possible, what about cross-platform issues (with moonlight) ? If it's not possible. Which language can i use to work with silverlight while being cross-platform ? Because of performance, a compilated language will be better ! Thanks for your expertise :)

  • Accessing current user personal certificate store within windows service

    - by Xeel
    I am working on an application which accesses a x.509 certificate from the current user store. This works fine when the application is run as an executable. However, when I try running the app as a windows service, it fails to find the certificate. I tried changing the LogOn property for the windowsservice console to set the right user, but that did not help. Is there any way I can access the particular user's (Administrator) certificate store? I am bound to use the certificate in the user store - else I can easily use the local machine store. Any help will be appreciated.

  • C# Dataset usage necessary before passing to GridView datasource?

    - by Goober
    Scenario Lets say for example I have a series of events that fire continually every half second presenting me with an object containing some bits of information. There are always between 10 and 15 objects that are being updated constantly. Since these bits of information are changing continually I want to display them in a GridView. When I do so, I want the user to see the data displayed in the gridview and actually be updated as opposed to just a continually extending list being printed and incrementing (like writeline on the console). Question Is the best way to achieve this to map my objects to a dataset and have the dataset mapped to the gridview? Thoughts Will this allow the gridview to just be "UPDATED" as opposed to being added to? Any implementation suggestions would be greatly appreciated. EDIT: it MUST be windows forms (I use DevExpress too)
