  • Errors when using a Ruby On Rails scaffold with a data type of interger

    - by bublebboy
    I am learning Ruby On Rails. I am on a shared hosting with Ruby version 1.8.1 and Rails version 2.3.10. I am working my way through a tutorial at http://railstutorial.org/chapters/a-demo-app?version=2.3#top and at one point in the tutorial it has me run: script/generate scaffold Micropost content:string user_id:interger The tutorial is using the default database, SQLite3. The command works and I use rake db:migrate to create the database. I can view the page listing the microposts (which is empty), but when I try to add a micropost (microposts/new) I get an error undefined method `user_id' for #<Micropost:0x7f710e4988e8> After doing some testing on my own it seems I experience the problem by using the data type of interger. While I understand that using a scaffold is not the best way of building a ruby on rails, I'm just beginning and would still like to know why I am experiencing this problem to help me better understand how rails works.

  • Cannot Login as root

    - by Josh Moore
    At my work we ship our product on pre-installed servers as a software/hardware package. We are using open SUSE 10.3 for the OS and we setup and we always log in with the root user to do maintenance on the box. Recently we just had box returned to us that the customer said the could not longer connect to the box through the network interface. So when I started to work on the box I run into the this problem: At the command prompt to login i type the user name "root" and hit enter. Then even before it asks me for a password I get "Login incorrect". I have never seen this behavior before and could not find any information about it online. Does anybody know what is going on? Thanks.

  • Want to save data field from form into two columns of two models.

    - by vette982
    I have a Profile model with a hasOne relationship to a Detail model. I have a registration form that saves data into both model's tables, but I want the username field from the profile model to be copied over to the usernamefield in the details model so that each has the same username. function new_account() { if(!empty($this->data)) { $this->Profile->modified = date("Y-m-d H:i:s"); if($this->Profile->save($this->data)) { $this->data['Detail']['profile_id'] = $this->Profile->id; $this->data['Detail']['username'] = $this->Profile->username; $this->Profile->Detail->save($this->data); $this->Session->setFlash('Your registration was successful.'); $this->redirect(array('action'=>'index')); } } } This code in my Profile controller gives me the error: Undefined property: Profile::$username Any ideas?

  • Firewall blocks FTP PASV response

    - by harper
    I have an FTP server that supports passive server mode (using PASV command). This works fine with Windows XP. When I want to access this server from Windows Vista or Windows 7 with firewall enabled I experience an immediate connection shutdown. A reset packet is sent to the server, and the socket is signaled that the server has reset the connection (which is not true). The problem disappears when the firewall is disabled. Connections to other FTP servers work correctly. The difference is that the server's response to PASV does not enclose the address field with parentheses. This is legal as documented in RFC-959 and RFC-1132. How can I configure the firewall to stop this bad behavior?

  • Hyper-v dynamic memory client machines always use maximum memory

    - by Eric P
    When I create a virtual machine in Hyper-V and set it up to use dynamic memory, the virtual machine will always use the maximum memory within the virtualized OS. Hyper-V will show the assigned memory at 514mb, but when I log into the server and pull up task manager, it will show 90% memory used. When I bump the maximum memory up to 4gb, I get the same result: 90% memory usage. Nothing is even running on the virtual machine other than a clean instal of Windows Server 2008 R2. I have also tried it with Windows 7 with the same results. Is this the expected behavior or is something setup wrong

  • Ampersand in JSON/PHP in POST

    - by svenkapudija
    I'm having a text field which is send via JSON and jQuery (wrapped with .toJSON function) to my server via AJAX and POST request. On PHP side I'm doing json_decode . Everything works but if I put ampersand (&) inside it splits up the POST parameter so its incomplete on PHP side (at least what var_dump($_POST) is writing out). Shouldn't the toJSON and json_decode do all the job (escaping)? I tried encodeURIComponent, & to &amp;, & to \u0026 and it's not working. What I'm doing wrong? AJAX call function execute() { this.setupUrl(); return $.ajax({ type: this.requestMethod, data: this.getDataParams(), url: this.url }); } function getDataParams() { if(this.data != undefined) { if(this.requestMethod == 'POST' || this.requestMethod == 'PUT') { return "data=" + $.toJSON(this.data); } else if (this.requestMethod == 'GET') { return this.data; } } else { return null; } }

  • Can Camel Jetty proxy URL share the webapplication context

    - by user1750353
    I am struggling with Camel Jetty Proxy Routes. At times, the routes exhibits inconsistent behavior. My Proxy app deployed with context root "Proxy", however, if give that as the context path for my proxy URL I get service not found error. If change the Proxy to an arbitrary context such as "Dummy" then the route works. Is that how camel jetty component works? From Path: jetty:http://0.0.0.0:6080/Proxy/PurchaseOrder/?matchOnUriPrefix=true&disableStreamCache=true&traceEnabled=true To Path: jetty:http://localhost:7001/Provider/PurchaseOrder/?bridgeEndpoint=true&throwExceptionOnFailure=false Another issue i noticed with jetty is If deploy both Proxy and Provider on the same app container(same listening port), then the route completely stops working saying "Provider/PurchaseOrder/" service not found. The only way the routes work is, both routes have to run different ports and the from route shouldn't share the webcontext path. I have requirement that if required I should be a able run both Proxy and Provider on the same container. Any help appreciated. Thanks,

  • Keep a javascript variable after an ajax call

    - by Guillaume le Floch
    I'm new in javascript and jQuery. I'm using ajax calls to get data from my server. The fact is, I'm losing my javascript variables after the call .. Here is what I did : the variable is define outside any function and treat in an other function. var a = 0; function myfunction(url){ $.ajax({ url: url, timeout: 20000, success: function(data){ // Do some stuff // The a variable is now undefined }, error: function(){ // Do some stuff } }); } Everything is working fine, the only thing is that I need to keep my variables ... but it looks like it's gone .. Does anyone know why? Thanks

  • How do I make control-click in Opera open new tabs?

    - by user21952-is-a-great-name
    Update: As of version 11.50, control-click opens the new tab in background, as desired. Yay! In Opera, as opposed to all other modern browsers I know, control-click does not open a new tab. Moreover, I couldn't find any good way to configure this behavior. The best available option seems to be this. However, it's so hacky that it won't work on HTTPS sites unless you enable user javascript there, which doesn't seem like a good idea. There also seem to be other proposed solutions, but none of them seem to work. I'd like this because my laptop has no middle mouse-button, and I'm a creature of habit. Do people have any ideas (for the latest version, 10.50)? I'd like ctrl-click to open a background tab, but I can do with foreground. Thank you!

  • Pass Success variable to code

    - by João Dias
    How can I pass a variable that has been calculated in the success callback of an ajax function, to the document.ready ?

How can I get this to work? Thank you

  • Multiple connections to a MySQL database in a single PHP script.

    - by st3
    There are multiple times in one page where I need to connect and subsequently query a MySQL database, yet my code won't let me. I think it might be something to do with how my files are nested but it makes no sense. I am opening the SQL connection in the header file. The top of the offending page looks like the following: <?php $page_title = 'Dashboard'; include('templates/header.inc'); // includes a 'require_once('mysqli_connect.php') and a small query to the database; require_once('includes/functions.php'); require_once('includes/dashboard_sql.php'); // Contains functions which connect to database (which are failing.) ?> I get the PHP error Notice: Undefined variable: dbc in /Library/WebServer/Documents/pediatory_site/includes/dashboard_sql.php Where $dbc is the database connection defined in mysqli_connect.php. If anyone could help me out that would be great.

  • Pop current directory until specific file is found

    - by edarroyo
    I'm interested in writing a script with the following behavior: See if a file, build.xml, exists in the current directory, if so run a command supplied through arguments to the script. If not, pop the current directory and look at the parent. Go to 1. The script would end once we find the file or we reach the root. Also, once the script finishes and control comes back to the user I want the current directory to be that one where the script was initially l I'm not very familiar with shell scripting but any help/guidance will be much appreciated.

  • Network-related icons suddenly removed

    - by Velcro
    Hello, On a fresh Windows 7 installation, I created some shortcuts icons to network shares on the Desktop. Without any warning, these icons are sometimes and randomly deleted from Desktop. I totally don't understand what it happens! They are not hidden, they just are simply deleted. This behavior occurs on one computer in my company. Others Windows 7 computers are not affected by that. And also it's the first time I encounter that. Do you have an idea about this problem? Thanks.

  • How can I stop Pages from bolding/italicizing ordered list item numbers/letters?

    - by donut
    I'm writing a long, technical document that uses a lot of ordered lists in Pages '09. Often when I bold or italicize the first bit of text I type for a list item it Pages applies the same styling to the letter or number of that list item. It's been doing this for the first 13 pages I've written and now I've found out that I need to undo that. Is there any place to change this behavior or easily fix existing list item numbers/letters that are styled? The only way I've found is to select the whole list item (all of its content) and removing teh styling (un-bolding and un-italicizing) and then going back in and re-applying my stylings to its content. Definitely not ideal.

  • How do I conditionally assign ruby variables to javascript variables?

    - by Tony
    I have a website where I need a javascript version of the "current user" object along with the ruby version. I have been assigning these variables doing something like this... Application Controller: def get_user begin @current_user = User.find(session[:user_id]) if session[:user_id] @current_user_json = @current_user.to_json rescue session.delete(:user_id) @current_user = nil @current_user_json = {} end end Web Page: var current_user = null; current_user_json = '<%= @current_user_json %>'; if(current_user_json != ''){ current_user = current_user_json.user; } Even when there is a current user, I get the current user is undefined. Probably because I am putting the current_user_json assignment around single quotes. However, if I don't put it around single quotes, I'll always get a javascript error when no user is logged in because the syntax is invalid - current_user_json = ; I think I am just looking at this completely wrong and there must be a better way. Given that this is probably a common thing to do, I wanted to get other people's opinion on how to create an object in javascript that is a duplicate of the ruby object.

    - by kusoksna
    I have Ubuntu 10.04 installation. When I open terminal, tab key works fine e.g. i type "apt-get install mysql" then press tab and see all options. But when I connect via ssh - tab key works only before first space. So it will do nothing in above example. I tried connect with different clients (ssh, putty, etc), and always same behavior. My question is: how to make tab key work properly? Is problem in server or client?

  • Windows 7 System Image Restore to SSD - SSD not detected?

    - by steviey
    I recently bought a new SSD (OCZ Vertex 2 120GB) as a replacement for my laptop HDD . I created a System Image on an external drive using the Win 7 backup and restore tool and then restored this image to the SSD using the Win 7 disk. AHCI is enabled in Win 7 and the BIOS, but it seems that windows is not detecting the disk as an SSD because, in the defragger, the disk is still available for defragging. Prefetch and Superfetch were also still enabled. I have manually disabled scheduled defragging, prefetch and superfetch. I have also checked that TRIM is enabled using: fsutil behavior query DisableDeleteNotify and the result is '0' (it is). Performance seems ok, but not quite as fast as I expected. Was restoring from a win7 generated system image a mistake? Am I getting optimal SSD performance?

  • Configure nagios to alert only when there are no mx servers available

    - by Aseques
    In my company there are two redundant MX servers, I would like to tell nagios to wake me in the night ONLY if both servers are down. The default behavior is to alert whenever one of the MX servers is down. I would like to set a timeperiod i.e. 23:00 to 06:00 when nagios only alerts me by sms in case both servers are down. I am using nagios3 but I couldn't find something like this in the docs. Solution: I've used this check_command in a service called MXservice: check_command check_service_cluster!"MXservice"!2!1!$SERVICESTATEID:mx1:SMTP$,$SERVICESTATEID:mx1:SMTP$ Thanks for all your help

  • How do I sync the Solution Explorer with the current File in Visual Studio?

    - by thepaulpage
    When I have an open code file in Visual Studio that I am editing I would like to keep that same file highlighted inside of the solution Explorer so that I know where I am at. What I'd really like is to change the focus to a different code file and the solution explorer to move to the file that I am editing. Further Explanation and example: I have a project with 2 files. Class1 and Class2. I open both files. The focus is on Class1. I click on the Class2 Tab, thereby changing the file that I am editing to Class2. Desired Behavior The solution explorer will highlight Class2.

  • overflow technique in stack

    - by metashockwave
    int main(void) { problem2(); } void doit2(void) { int overflowme[16]; //overflowme[37] =0; } void problem2(void) { int x = 42; doit2(); printf("x is %d\n", x); printf("the address of x is 0x%x\n", &x); } Would someone help me understand why overflowme[37] =0; from the doit2 function will overwrite the value of x? (please include Program Counter and Frame Pointer of the function doit2 in your explanation) Thank you! It works every time with Project properties-Configuration properties-C/C++ -Code Generation-Basic Runtime Checks set to "Default". so it's not an undefined behavior.

  • get focus only by clicking the title bar of xterm

    - by sandyleo
    ...I've suffered this problem many times and so do my colleagues Sometimes after you stroked some keyboard and mouse combinations this behavior showed up : you have to click a xterm's title bar to focus on that term so that you can input, instead of any places in that window. Whatever you do, minimize, resize don't help. This only thing you can do is logout that session but all the working history will be gone(of course I can save that but it's awkward) I'm eagerly wondering is there any solutions to this? I use ctrix XenApp plugin 11.0. The other platform info: Linux 2.6.9-67.ELsmp x86_64 OS: RedHat Enterprise Linux 4.0 U6 xterm:X.Org 6.8.2(192) THanks!

  • How do I send the ckeditor config using jQuery service?

    - by syn4k
    My service is built and it is sending the config variable to my js file: [['SpellChecker','-','Undo','Redo','-','Bold','Italic','Underline','NumberedList','BulletedList']] The above is assigned to my javascript like so: var config = "<?= stripslashes($_REQUEST['config']) ?>"; I can alert out the config just fine: console.log(config) does send back the correct data... However, I get an error thrown in my console!: v is undefined [Break On This Error] var u=n.toolbox.toolbars,v=n.config.to...aximize','ShowBlocks','-','About']]; If I comment out the config: //CKEDITOR.config.toolbar = config; everything works fine but the configuration doesn't exist, of course...

  • To use package properly, how to arrange directory, file name, unit test file?

    - by Stephen Hsu
    My source files tree is like this: /src /pkg /foo foo.go foo_test.go Inside foo.go: package foo func bar(n int) { ... } inside foo_test.go: package foo func testBar(t *testing.T) { bar(10) ... } My questions are: Does package name relates to directory name, source file name? If there is only one source file for a package, need I put it in a directory? Should I put foo.go and foo_test.go in the same package? In the foo_test.go, as it's in the same package as foo.go, I didn't import foo. But when I compile foo_test.go with 6g, it says bar() is undefined. What should I do?

  • How can I make zsh completion behave like Bash completion?

    - by Nate
    I switched to zsh, but I dislike the completion. If I have 20 files, each with a shared prefix, on pressing tab, zsh will fully complete the first file, then continue going through the list with each press of tab. If I want one near the end, I would have to press tab many times. In bash, this was simple - press tab and I would get the prefix. If I continued typing (and pressing tab), bash would complete as far as it could be certain of. I find this behavior to be much more intuitive but prefer the other features of zsh to bash. Is there a way to get this style of completion? Google suggested setopt bash_autolist, but this had no effect for me (and no error message was printed upon starting my shell). Thanks.

  • How to solve the problem that Chrome doesn't obey "Show Window side by side" on Win7?

    - by Jian Lin
    If I bring out Firefox and Chrome, and right click on the task bar and choose "Show Windows side by side", Chrome will not be arranged side by side. But if it is Firefox and IE, then the 2 windows will in fact be arranged side by side. If it is Chrome showing and we press and hold "Window key" and LEFT ARROW, then in fact it does move to the left as a half size window. So Chrome partially work on Win7 for the expected behavior. Any method to make it work for the first case? thanks.
