  • Capistrano 3, Rails 4, database configuration does not specify adapter

    - by Kazmin
    When I start cap production deploy it fails like this: DEBUG [4ee8fa7a] Command: cd /home/deploy/myapp/releases/releases/20131025212110 && (RVM_BIN_PATH=~/.rvm/bin RAILS_ENV= ~/.rvm/bin/myapp_rake assets:precompile ) DEBUG [4ee8fa7a] rake aborted! DEBUG [4ee8fa7a] database configuration does not specify adapter You can see that "RAILS_ENV=" is actually empty and I'm wondering why that might be happening? I assume that this is the reason for the latter error that I don't have a database configuration. The deploy.rb file is below: set :application, 'myapp' set :repo_url, '[email protected]:developer/myapp.git' set :branch, :master set :deploy_to, '/home/deploy/myapp/releases' set :scm, :git set :devpath, "/home/deploy/myapp_development" set :user, "deploy" set :use_sudo, false set :default_env, { rvm_bin_path: '~/.rvm/bin' } set :keep_releases, 5 namespace :deploy do desc 'Restart application' task :restart do on roles(:app), in: :sequence, wait: 5 do # Your restart mechanism here, for example: within release_path do execute " bundle exec thin restart -O -C config/thin/production.yml" end end end after :restart, :clear_cache do on roles(:web), in: :groups, limit: 3, wait: 10 do within release_path do end end end after :finishing, 'deploy:cleanup' end?

  • Bind Data after TCP receive.

    - by gtas
    I have this strange problem all day now. I dunno if you handled something similar. I used two different serializers and now i know its not this problem. Im sending some data over TCP Sockets. Serialize - Send - Deserialize, everything works ok, i can get my objects search through them, use they're properties! But, if e.g receive a BusinessObject[] and convert into List<BusinessObject>, then bind the list in a Control.DataSource = businessObjectList; BOOM! NotSupportedException. Tried it with 3 different controls. Same behaviour. My head is empty of ideas right now!! The Send TCP happens on Desktop Framework, Receive on Compact Framework. But i dont think this has to do with anything. I wish for an explanation on this!

  • How do I impliment a hidden field in a post form so users can't accidentally double post? (PHP/Mysql

    - by ggfan
    When users submit a form, they will sometimes click refresh or backspace then resubmit which causes multiple entries in mysql. How can i prevent mysql from allowing more than 1 of the same entry? People suggested a hidden field with a value, but how do I use that? <label for="state" class="styled">State:</label> <input type="text" id="state" name="state" value="<?php if (!empty($state)) echo $state; ?>" size="30" /><br /> //a hidden field of a certain value? ________________________________________ <input type="submit" value="Post Ad!" name="submit" /> //php to insert to mysql $query4 = "INSERT INTO posting (state) VALUES ('$state')"; mysqli_query($dbc, $query4);

  • How can I safely raise events in an AsyncCallback?

    - by cyclotis04
    I'm writing a wrapper class around a TcpClient which raises an event when data arrives. I'm using BeginRead and EndRead, but when the parent form handles the event, it's not running on the UI thread. I do I need to use delegates and pass the context into the callback? I thought that callbacks were a way to avoid this... void ReadCallback(IAsyncResult ar) { int length = _tcpClient.GetStream().EndRead(ar); _stringBuilder.Append(ByteArrayToString(_buffer, length)); BeginRead(); OnStringArrival(EventArgs.Empty); }

  • How do I find out if the variable is declared in Python?

    - by golergka
    I want to use a module as a singleton referenced in other modules. It looks something like this (that's not actually a code I'm working on, but I simplified it to throw away all unrelated stuff): main.py import singleton import printer def main(): singleton.Init(1,2) printer.Print() if __name__ == '__main__': pass singleton.py variable1 = '' variable2 = '' def Init(var1, var2) variable1 = var1 variable2 = var2 printer.py import singleton def Print() print singleton.variable1 print singleton.variable2 I expect to get output 1/2, but instead get empty space. I understand that after I imported singleton to the print.py module the variables got initialized again. So I think that I must check if they were intialized before in singleton.py: if not (variable1): variable1 = '' if not (variable2) variable2 = '' But I don't know how to do that. Or there is a better way to use singleton modules in python that I'm not aware of :)

    - by Fordnox
    I have a response from remote server like this: /home/computer/Downloads |-- /home/computer/Downloads/Apple | `-- /home/computer/Downloads/Apple/Pad |-- /home/computer/Downloads/Empty_Folder `-- /home/computer/Downloads/Subfolder |-- /home/computer/Downloads/Subfolder/Empty `-- /home/computer/Downloads/Subfolder/SubSubFolder `-- /home/computer/Downloads/Subfolder/SubSubFolder/Test this is the output for command computer@athome:$ tree -df --noreport -L 5 /home/computer/Downloads/ I would like to parse this string to recursive php array or object, something like this.

Can someone help me write this function. Please note that this is response from remote server and php functions can not scan any remote dir.

  • Invoke a cleanup method for java user thread, when JVM stops the thread

    - by user309281
    Hi All I have J2SE application running in linux. I have stop application script in which i am doing kill of the J2SE pid. This J2SE application has 6 infinitely running user threads,which will be polling for some specific records in backend DB. When this java pid is killed, I need to perform some cleanup operations for each of the long running thread, like connecting to DB and set status of some transactions which are in-progress to empty. Is there a way to write a method in each of the thread, which will be called when the thread is going to be stopped, by JVM.

  • Find products that have a list of attributes.

    - by bellesebastien
    I'm stuck trying to solve a problem that's proving to be more difficult than it seems. Consider there is a table that associates products with attributes, it looks like this: Products_id | Attribute_id 21 | 456 21 | 231 21 | 26 22 | 456 22 | 26 22 | 116 23 | 116 23 | 231 Next, I have a list of attribute_ids which I want to use in order to get the products that have all the attributes in that list. For example if I search in the table above using this list (456, 26) I should get these product_ids 21 and 22. Another example, if I search for (116, 231) I should get an empty response since there are no products that have both these attributes. How can I achieve this using one query? I hope I made my question clear. Thanks.

  • How to get elements from an object in C#?

    - by Drew
    I am using the AutoCompleteBox in WPF, I populate the suggestions with a List that consists of four fields. When the user selects an item and I reach my eventHandler, i can see that MyAutoCompleteBox.SelectedItem is an object that has my four values, if i hover this text in the debugger i can see the four values listed, however i don't know how to access these values in the code. I tried List<Codes> selected = MyAutoCompleteBox.SelectedItem as List<Codes>; where Codes is my List. selected returns as null and empty every time. Is there a way to get to these values? Thanks!

    Hi Guys, I am using C#. I am having below code in C#: protected override void OnInit(EventArgs e) { try { if (Session["boolSignOn"].ToString() == "true".ToString()) { lblPanelOpen.Text = Session["panelOpen"].ToString(); } else { lblPanelOpen.Text = Session["panelOpen"].ToString(); } } catch (Exception ex) { Logger.Error("Error processing request:" + ex.Message); } } protected override void OnLoad(EventArgs e) { try { if (!string.IsNullOrEmpty(Session["panelOpen"].ToString())) { lblPanelOpen.Text = string.Empty; Session.Remove("panelOpen"); } } catch (Exception ex) { Logger.Error("Unable to remove the session variable:" + ex.Message); } } In above code I am having a Session["panelOpen"] variable which is created from another user control and once my page is trying to render, I am storing Session["panelOpen"] in my hidden lblPanelOpen.Text on page OnInit() method, however when page is loaded completely then I am trying to remove the session variable.

  • Pure HTML + JavaScript client side templating

    - by Dev er dev
    I want to have achieve something similar to Java Tiles framework using only client side technologies (no server side includes). I would like to have one page, eg layout.html which will contain layout definition. Content placeholder in that page would be empty #content div tag. I would like to have different content injected on that page based on url. Something like layout.html?content=main or layout.html?content=edit will display page with content replaced with main.html or edit.html. The goal is to avoid duplicating code, even for layout, and to compose pages without server-side templating. What approach would you suggest? EDIT: I don't need a full templating library, just a way to compose a pages, similar for what tiles do.

  • The Definition of Regular Languages

    - by AraK
    Good Day, I have tried, and burned my brain to understand the definition of Regular Languages in Discrete Mathematics and its Applications(Rosen) without reaching the goal of understanding why the definition is like that in this book. On page(789), I am rephrasing the definition: Type 3 grammars are defined as: w1 --> w2 Where w1 is a non-terminal, and w2 is of the form: w2 = aB w2 = a Where B is a non-terminal, and a is a terminal. A special case is when w1 is the starting symbol and w2 is lambda(the empty string): w1 = S S --> lambda Two questions I couldn't find an answer for. First, Why can't w2 be of the form Ba. Second, Why lambda is only allowed for the starting symbol only. The book states that, regular languages are equivalent to Finite State Automaton, and we can easily see that a we can build FSA for both cases. I took a look at other resources, and these restrictions don't exist in these resources. Thanks,

  • Visual Studio 2008. MFC event wizard broken

    - by G Forty
    OK, so it's almost a programming question - The VS2008 dialog event wizard has stopped working. Double-clicking on a button in an MFC dialog project does not fire the wizard as usual and a right-click to get to the 'Add Event Handler...' shows a dialog with no message types. Further to this the MFC message mapping and virtual class listing that generally appears in the properties window (Alt + Enter) is now empty. Has anyone elese seen this and if so, how'd they fix it? I have 'repaired' my VS08 installation ... Thx++ Jerry

  • Facebook Graph API: Feed publishing showing up as link type instead of status?

    - by Redth
    So I'm publishing to a Facebook Group's Feed in my app, using the Graph API. It works fine, except facebook keeps treating the published info as a 'link' feed item type instead of 'status' like it does when I enter the same from facebook's site. eg: string url = "https://graph.facebook.com/<id-of-group/feed?access_token=<access-token>"; string data = "message=hello"; webClient.UploadString(url, "POST", data); Now when I pull the feed items, the json that is returned has "item":"link", with "link":"http://www.facebook.com", whereas I'd expect it to be "item":"status" and no or an empty "link" property. Any ideas?

  • Ajax Fancy Capture in CakPHP

    - by Constantin.FF
    I have found a nice ajax capture which i would like to use in a CakePHP framework website. The plugin can be found here: http://www.webdesignbeach.com/beachbar/ajax-fancy-captcha-jquery-plugin What I have tried: in the controller: public function index($slug = null, $capture = false) { if($capture AND $capture =="get_capture"){ $rand = rand(0,4); $_SESSION['captcha'] = $rand; echo $rand; die; } if (!empty($this->data) && $_POST['captcha'] == $_SESSION['captcha']) { .... save the post } } in the view: $selectURL = " $(function() { $('.ajax-fc-container').captcha({ borderColor: 'silver', captchaDir: 'http://localhost/img/capture', url: 'http://localhost/contacts/index/contacts/get_capture', formId: 'MessageIndexForm', }); });"; $this->Html->scriptBlock($selectURL, array('inline' => false)); also I have tried with url: 'http://localhost/js/capture.php' which is the original file coming with the plugin but still not working.

  • Loop over a file and write the next line if a condition is met

    - by 111078384259264152964
    Having a hard time fixing this or finding any good hints about it. I'm trying to loop over one file, modify each line slightly, and then loop over a different file. If the line in the second file starts with the line from the first then the following line in the second file should be written to a third file. !/usr/bin/env python with open('ids.txt', 'rU') as f: with open('seqres.txt', 'rU') as g: for id in f: id=id.lower()[0:4]+'_'+id[4] with open(id + '.fasta', 'w') as h: for line in g: if line.startswith(''+ id): h.write(g.next()) All the correct files appear, but they are empty. Yes, I am sure the if has true cases. :-) "seqres.txt" has lines with an ID number in a certain format, each followed by a line with data. The "ids.txt" has lines with the ID numbers of interest in a different format. I want each line of data with an interesting ID number in its own file. Thanks a million to anyone with a little advice!

  • Are there any good videos out there on Java Design Patterns?

    - by Becky Reamy
    My team would like to spend some time at lunch learning design patterns. Previously, we watched some videos on Javascript which we found very useful as a way to start discussions. We would like to do the same thing with design patterns so that we don't have to spend a lot of time (outside of work) researching individual patterns in order to give a presentation. I did a little searching and came up fairly empty handed. Any help would be appreciated. It doesn't even have to be a video, even something that we can listen to (maybe a book on tape even).

  • Reporting services genius only: a fast way to get Reporting Services local site working?

    - by Junior Mayhé
    Hello I was here trying to figure out why my Reports manager is empty, there's no tabs at all. I installed SQL Server 2008 complete, but didn't not configure Reporting Services. When installing SQL Server 2008, this Windows 7 version didn't have yet IIS installed, I installed it later. I don't see where is this localhost/Reports physically on my Hard Drive, where is the physic folder? I don't see on IIS where is Report folder, would it exist? The site settings people talk about, I can't find it. The "Reporting Services" service is running on automatic at SQL Server Configuration Manager. How can I get Reporting Services this working without struggling? (I can't see why is necessary to customize all these user permissions)

  • Looking for an elegant way to store one-to-many relationship in coredata when order is important

    - by Eric Schweichler
    I've been trying to come up with a way to solve my problem, but every solution I can think of is messy and makes me want to retch. I have a one-to-many relationship, consisting of a Team object that can have many Member objects. When I built my data model using Xcode, I was given the default NSSet in which to store the member objects, Unfortunately Sets are not ordered and I need to preserve the order of the Member objects and I need to know if there are empty spaces between Members. I thought of Using an NSArray in place of the NSSet and creating a dummy Member object in my data store that I could use to mark vacant a spot between to Member objects, but that solution really feels like too much of a hack to me. Since I'll always have to filter out this dummy Member from any queries. An NSDictionary would be perfect as I could store the Member object references and their positions as Object-Key pairs, (taking care of both order and vacancies) but apparently CoreData does not support NSDictionary. Has anyone had a similar need, and devised a simple solution?

  • facebook iframe application gives null GET/POST

    - by misterjinx
    hey everybody, I came up to something really strange with a facebook iframe application. I don't know why but my global supervariables $_GET and $_POST are empty (nulls actually)! As far as i know, when using iframe for doing applications all the specific facebook variables are kept inside the $_GET variable. But for some reason now I don't have anything. I don't know what might be the problem. And as this wouldn't be enough, when i submit a form using POST as method, my $_POST variable is also null! What you guys think might be the problem? I've spent half a day trying to figure this out, but i didn't get any result.

  • Assembly.CodeBase: when is it no file-URI?

    - by Marc Wittke
    Assembly.Location gives a plain path to the assembly. Unfortunately this is empty when running in a shadowed environment, such as unit test or ASP.NET. Hovever, the Codebase property is available and provides a URI that can be used instead. In which cases it returns no URI starting with file:///? Or in other words: what are the cases in which this won't work or will return unusable results? Assembly assembly = GetType().Assembly; Uri codeBaseUri = new Uri(assembly.CodeBase); string path = codeBaseUri.LocalPath;
