  • Using AJAX to display error message Ruby on Rails

    - by bgadoci
    I have built a blog using Ruby on Rails. New to both. I am implementing AJAX pretty effectively until I get to the error handling portion. I allow for comments on posts and do this by rendering a comment partial and remote form in the /views/posts/show.html.erb page. Upon successful save of a comment the show page is updated using views/comments/create.js.rjs and displays a flash notice. I am simply trying to flash a notice when it doesn't save. Searched around and worked this a bit on my own. Can't get it to fly. Here is my code: /views/posts/show.html.erb <div id="comments"> <%= render :partial => @post.comments %> <div id="notice"><%= flash[:notice] %></div> </div> <% remote_form_for [@post, Comment.new] do |f| %> <p> <%= f.label :body, "New Comment" %><br/> <%= f.text_area (:body, :class => "textarea") %> </p> <p> <%= f.label :name, "Name" %><br/> <%= f.text_field (:name, :class => "textfield") %> </p> <p> <%= f.label :email, "Email" %><br/> <%= f.text_field (:email, :class => "textfield") %> </p> <p><%= f.submit "Add Comment" %></p> <% end %> /views/comments/_comment.html.erb <% div_for comment do %> <div id="comment-wrapper"> <% if admin? %> <div id="comment-destroy"><%=link_to_remote "X", :url => [@post, comment], :method => :delete %></div> <% end %> <%= h(comment.body) %><br/><br/> <div class="small">Posted <%= time_ago_in_words(comment.created_at) %> ago by <%= h(comment.name) %> <% if admin? %> | <%= h(comment.email) %> <% end %></div> </div> <% end %> /views/comments/create.js.rjs page.insert_html :bottom, :comments, :partial => @comment page[@comment].visual_effect :highlight page[:new_comment].reset page.replace_html :notice, flash[:notice] flash.discard CommentsController#create def create @post = Post.find(params[:post_id]) @comment = @post.comments.create!(params[:comment]) respond_to do |format| if @comment.save flash[:notice] = "Thanks for adding this comment" format.html { redirect_to @post } format.js else flash[:notice] = "Make sure you include your name and a valid email address" format.html { redirect_to @post } format.js end end end

  • C# WebClient - View source question

    - by Jim
    I'm using a C# WebClient to post login details to a page and read the all the results. The page I am trying to load includes flash (which, in the browser, translates into HTML). I'm guessing it's flash to avoid being picked up by search engines??? The flash I am interested in is just text (not an image/video) etc and when I "View Selection Source" in firefox I do actually see the text, within HTML, that I want to see. (Interestingly when I view the source for the whole page I do not see the text, within HTML, that I want to see. Could this be related?) Currently after I have posted my login details, and loaded the HTML back, I see the page which does NOT show the flash HTML (as if I had viewed source for the whole page). Thanks in advance, Jim PS: I should point out that the POST is actually working, my log in is successful.

  • Do all C compilers allow functions to return structures?

    - by Jordan S
    I am working on a program in C and using the SDCC compiler for a 8051 architecture device. I am trying to write a function called GetName that will read 8 characters from Flash Memory and return the character array in some form. I know that it is not possible to return an array in C so I am trying to do it using a struct like this: //********************FLASH.h file******************************* MyStruct GetName(int i); //Function prototype #define NAME_SIZE 8 typedef struct { char Name[NAME_SIZE]; } MyStruct; extern MyStruct GetName(int i); // *****************FLASH.c file*********************************** #include "FLASH.h" MyStruct GetName( int i) { MyStruct newNameStruct; //... // Fill the array by reading data from Flash //... return newNameStruct; } I don't have any references to this function yet but for some reason, I get a compiler error that says "Function cannot return aggregate." Does this mean that my compiler does not support functions that return structs? Or am I just doing something wrong?

  • choosing an image locally from http url and serving that image without a server round trip

    - by serverman
    Hi folks I am a complete novice to Flash (never created anything in flash). I am quite familiar with web applications (J2EE based) and have a reasonable expertise in Javascript. Here is my requirement. I want the user to select (via an html form) an image. Normally in the post, this image would be sent to server and may be stored there to be served later. I do not want that. I want to store this image locally and then serve it via HTTP to the user. So, the flow is: 1. Go to the "select image url":mywebsite.com/selectImage Browse the image and select the image This would transfer control locally to some code running on the client (Javascript or flash), which would then store the image locally at some place on the client machine. Go to the "show image url": mywebsite.com/showImage This would eventually result in some client code running on the browser that retrieves the image and renders it (without any server round trips.) I considered the following options: Use HTML5 local storage. Since I am a complete novice to flash, I looked into this. I found that it is fairly straightforward to store and retrieve images in javascript (only strings are allowed but I am hoping storing base64 encoded strings would work at least for small images). However, how do I serve the image via http url that points to my server without a server round trip? I saw the interesting article at http://hacks.mozilla.org/category/fileapi/ but that would work only in firefox and I need to work on all latest browsers (at least the ones supporting HTML5 local storage) Use flash SharedObjects. OK, this would have been good - the only thing is I am not sure where to start. Snippets of actionscripts to do this are scattered everywhere but I do not know how to use those scripts in an actual html page:) I do not need to create any movies or anything - just need to store an image and serve it locally. If I go this route, I would also use it to store other "strings" locally. If you suggest this, please give me the exact steps (could be pointers to other web sites) on how to do this. I would like to avoid paying for any flash development environment software ideally:) Thank you!

  • Help me refactor this nasty Ruby if/else statement

    - by Suborx
    Hello, so I have this big method in my application for newsletter distribution. Method is for updating rayons and I need to assign a user to rayon. I have relation n:n through table colporteur_in_rayons which has attributes since_date and until_date.

  • Paperclip: Stay put on edit

    - by EricR
    When a user edits something in my application, they're forced to re-upload their image via paperclip even if they aren't changing it. Failing to do so will cause an error, since I validate_presence_of :image. This is quite annoying. How can I make it so Paperclip won't update its attributes if a user simply doesn't supply a new image on an edit? The photo controller is fresh out of Rails' scaffold generator. The rest of the source code is provided below. models/accommodation.rb class Accommodation < ActiveRecord::Base attr_accessible :photo validates_presence_of :photo has_one :photo has_many :notifications belongs_to :user accepts_nested_attributes_for :photo, :allow_destroy => true end controllers/accommodation_controller.rb class AccommodationsController < ApplicationController def index @accommodations = Accommodation.all end def show @accommodation = Accommodation.find(params[:id]) rescue ActiveRecord::RecordNotFound flash[:error] = "Accommodation not found." redirect_to :home end def new @accommodation = current_user.accommodations.build @accommodation.build_photo end def create @accommodation = current_user.accommodations.build(params[:accommodation]) if @accommodation.save flash[:notice] = "Successfully created your accommodation." redirect_to @accommodation else @accommodation.build_photo render :new end end def edit @accommodation = Accommodation.find(params[:id]) @accommodation.build_photo rescue ActiveRecord::RecordNotFound flash[:error] = "Accommodation not found." redirect_to :home end def update @accommodation = Accommodation.find(params[:id]) if @accommodation.update_attributes(params[:accommodation]) flash[:notice] = "Successfully updated accommodation." redirect_to @accommodation else @accommodation.build_photo render :edit end end def destroy @accommodation = Accommodation.find(params[:id]) @accommodation.destroy flash[:notice] = "Successfully destroyed accommodation." redirect_to :inkeep end end models/photo.rb class Photo < ActiveRecord::Base attr_accessible :image, :primary belongs_to :accommodation has_attached_file :image, :styles => { :thumb=> "100x100#", :small => "150x150>" } end

  • javascript|jquery|ajax|etc.. How to download/read only first 80KB of file.

    - by DeusAphor
    I am making a grease-monkey plugin for a website that has many flash files. I'd like to make a hash of the flash, the problem is that the flash files are up to 10(total) * 10MEGS. This is slow; I'd like to be able to only grab the first 80KB to hash. The end result would be an easy way to blacklist certain flash files containing unwanted content. Is this possible? Suggestions? Code examples are greatly appreciated!

  • Move Files from a Failing PC with an Ubuntu Live CD

    - by Trevor Bekolay
    You’ve loaded the Ubuntu Live CD to salvage files from a failing system, but where do you store the recovered files? We’ll show you how to store them on external drives, drives on the same PC, a Windows home network, and other locations. We’ve shown you how to recover data like a forensics expert, but you can’t store recovered files back on your failed hard drive! There are lots of ways to transfer the files you access from an Ubuntu Live CD to a place that a stable Windows machine can access them. We’ll go through several methods, starting each section from the Ubuntu desktop – if you don’t yet have an Ubuntu Live CD, follow our guide to creating a bootable USB flash drive, and then our instructions for booting into Ubuntu. If your BIOS doesn’t let you boot using a USB flash drive, don’t worry, we’ve got you covered! Use a Healthy Hard Drive If your computer has more than one hard drive, or your hard drive is healthy and you’re in Ubuntu for non-recovery reasons, then accessing your hard drive is easy as pie, even if the hard drive is formatted for Windows. To access a hard drive, it must first be mounted. To mount a healthy hard drive, you just have to select it from the Places menu at the top-left of the screen. You will have to identify your hard drive by its size. Clicking on the appropriate hard drive mounts it, and opens it in a file browser. You can now move files to this hard drive by drag-and-drop or copy-and-paste, both of which are done the same way they’re done in Windows. Once a hard drive, or other external storage device, is mounted, it will show up in the /media directory. To see a list of currently mounted storage devices, navigate to /media by clicking on File System in a File Browser window, and then double-clicking on the media folder. Right now, our media folder contains links to the hard drive, which Ubuntu has assigned a terribly uninformative label, and the PLoP Boot Manager CD that is currently in the CD-ROM drive. Connect a USB Hard Drive or Flash Drive An external USB hard drive gives you the advantage of portability, and is still large enough to store an entire hard disk dump, if need be. Flash drives are also very quick and easy to connect, though they are limited in how much they can store. When you plug a USB hard drive or flash drive in, Ubuntu should automatically detect it and mount it. It may even open it in a File Browser automatically. Since it’s been mounted, you will also see it show up on the desktop, and in the /media folder. Once it’s been mounted, you can access it and store files on it like you would any other folder in Ubuntu. If, for whatever reason, it doesn’t mount automatically, click on Places in the top-left of your screen and select your USB device. If it does not show up in the Places list, then you may need to format your USB drive. To properly remove the USB drive when you’re done moving files, right click on the desktop icon or the folder in /media and select Safely Remove Drive. If you’re not given that option, then Eject or Unmount will effectively do the same thing. Connect to a Windows PC on your Local Network If you have another PC or a laptop connected through the same router (wired or wireless) then you can transfer files over the network relatively quickly. To do this, we will share one or more folders from the machine booted up with the Ubuntu Live CD over the network, letting our Windows PC grab the files contained in that folder. As an example, we’re going to share a folder on the desktop called ToShare. Right-click on the folder you want to share, and click Sharing Options. A Folder Sharing window will pop up. Check the box labeled Share this folder. A window will pop up about the sharing service. Click the Install service button. Some files will be downloaded, and then installed. When they’re done installing, you’ll be appropriately notified. You will be prompted to restart your session. Don’t worry, this won’t actually log you out, so go ahead and press the Restart session button. The Folder Sharing window returns, with Share this folder now checked. Edit the Share name if you’d like, and add checkmarks in the two checkboxes below the text fields. Click Create Share. Nautilus will ask your permission to add some permissions to the folder you want to share. Allow it to Add the permissions automatically. The folder is now shared, as evidenced by the new arrows above the folder’s icon. At this point, you are done with the Ubuntu machine. Head to your Windows PC, and open up Windows Explorer. Click on Network in the list on the left, and you should see a machine called UBUNTU in the right pane. Note: This example is shown in Windows 7; the same steps should work for Windows XP and Vista, but we have not tested them. Double-click on UBUNTU, and you will see the folder you shared earlier! As well as any other folders you’ve shared from Ubuntu. Double click on the folder you want to access, and from there, you can move the files from the machine booted with Ubuntu to your Windows PC. Upload to an Online Service There are many services online that will allow you to upload files, either temporarily or permanently. As long as you aren’t transferring an entire hard drive, these services should allow you to transfer your important files from the Ubuntu environment to any other machine with Internet access. We recommend compressing the files that you want to move, both to save a little bit of bandwidth, and to save time clicking on files, as uploading a single file will be much less work than a ton of little files. To compress one or more files or folders, select them, and then right-click on one of the members of the group. Click Compress…. Give the compressed file a suitable name, and then select a compression format. We’re using .zip because we can open it anywhere, and the compression rate is acceptable. Click Create and the compressed file will show up in the location selected in the Compress window. Dropbox If you have a Dropbox account, then you can easily upload files from the Ubuntu environment to Dropbox. There is no explicit limit on the size of file that can be uploaded to Dropbox, though a free account begins with a total limit of 2 GB of files in total. Access your account through Firefox, which can be opened by clicking on the Firefox logo to the right of the System menu at the top of the screen. Once into your account, press the Upload button on top of the main file list. Because Flash is not installed in the Live CD environment, you will have to switch to the basic uploader. Click Browse…find your compressed file, and then click Upload file. Depending on the size of the file, this could take some time. However, once the file has been uploaded, it should show up on any computer connected through Dropbox in a matter of minutes. Google Docs Google Docs allows the upload of any type of file – making it an ideal place to upload files that we want to access from another computer. While your total allocation of space varies (mine is around 7.5 GB), there is a per-file maximum of 1 GB. Log into Google Docs, and click on the Upload button at the top left of the page. Click Select files to upload and select your compressed file. For safety’s sake, uncheck the checkbox concerning converting files to Google Docs format, and then click Start upload. Go Online – Through FTP If you have access to an FTP server – perhaps through your web hosting company, or you’ve set up an FTP server on a different machine – you can easily access the FTP server in Ubuntu and transfer files. Just make sure you don’t go over your quota if you have one. You will need to know the address of the FTP server, as well as the login information. Click on Places > Connect to Server… Choose the FTP (with login) Service type, and fill in your information. Adding a bookmark is optional, but recommended. You will be asked for your password. You can choose to remember it until you logout, or indefinitely. You can now browse your FTP server just like any other folder. Drop files into the FTP server and you can retrieve them from any computer with an Internet connection and an FTP client.

  • Is it possible to repair a Cisco 3500 XL (3548) switch with POST Error messages?

    - by Alex
    I've got an old Cisco 3500 XL, and it seems to have hardware issues. I've loaded the latest IOS and cleared all config. Does anyone have any experience fixing the switch core? I'm a reasonably competent SMD solderer, can I replace/reflow some chips? I've checked the power supply voltages and it's all within tolerance, and no visible signs of any component damage. Some chips are hot to the touch. I understand that these were EOL as of 2007, but should have a lifetime warranty for the electronics. I don't have a Cisco support contract, so I can't file a ticket. What should I do?

  • Windows 7: How to place SuperFetch cache on an SSD?

    - by Ian Boyd
    I'm thinking of adding a solid state drive (SSD) to my existing Windows 7 installation. I know I can (and should) move my paging file to the SSD: Should the pagefile be placed on SSDs? Yes. Most pagefile operations are small random reads or larger sequential writes, both of which are types of operations that SSDs handle well. In looking at telemetry data from thousands of traces and focusing on pagefile reads and writes, we find that Pagefile.sys reads outnumber pagefile.sys writes by about 40 to 1, Pagefile.sys read sizes are typically quite small, with 67% less than or equal to 4 KB, and 88% less than 16 KB. Pagefile.sys writes are relatively large, with 62% greater than or equal to 128 KB and 45% being exactly 1 MB in size. In fact, given typical pagefile reference patterns and the favorable performance characteristics SSDs have on those patterns, there are few files better than the pagefile to place on an SSD. What I don't know is if I even can put a SuperFetch cache (i.e. ReadyBoost cache) on the solid state drive. I want to get the benefit of Windows being able to cache gigabytes of frequently accessed data on a relativly small (e.g. 30GB) solid state drive. This is exactly what SuperFetch+ReadyBoost (or SuperFetch+ReadyDrive) was designed for. Will Windows offer (or let) me place a ReadyBoost cache on a solid state flash drive connected via SATA? A problem with the ReadyBoost cache over the ReadyDrive cache is that the ReadyBoost cache does not survive between reboots. The cache is encrypted with a per-session key, making its existing contents unusable during boot and SuperFetch pre-fetching during login. Update One I know that Windows Vista limited you to only one ReadyBoost.sfcache file (I do not know if Windows 7 removed that limitation): Q: Can use use multiple devices for EMDs? A: Nope. We've limited Vista to one ReadyBoost per machine Q: Why just one device? A: Time and quality. Since this is the first revision of the feature, we decided to focus on making the single device exceptional, without the difficulties of managing multiple caches. We like the idea, though, and it's under consideration for future versions. I also know that the 4GB limit on the cache file was a limitation of the FAT filesystem used on most USB sticks - an SSD drive would be formatted with NTFS: Q: What's the largest amount of flash that I can use for ReadyBoost? A: You can use up to 4GB of flash for ReadyBoost (which turns out to be 8GB of cache w/ the compression) Q: Why can't I use more than 4GB of flash? A: The FAT32 filesystem limits our ReadyBoost.sfcache file to 4GB Can a ReadyBoost cache on an NTFS volume be larger than 4GB? Update Two The ReadyBoost cache is encrypted with a per-boot session key. This means that the cache has to be re-built after each boot, and cannot be used to help speed boot times, or latency from login to usable. Windows ReadyDrive technology takes advantage of non-volatile (NV) memory (i.e. flash) that is incorporated with some hybrid hard drives. This flash cache can be used to help Windows boot, or resume from hibernate faster. Will Windows 7 use an internal SSD drive as a ReadyBoost/*ReadyDrive*/SuperFetch cache? Is it possible to make Windows store a SuperFetch cache (i.e. ReadyBoost) on a non-removable SSD? Is it possible to not encrypt the ReadyBoost cache, and if so will Windows 7 use the cache at boot time? See also SuperUser.com: ReadyBoost + SSD = ? Windows 7 - ReadyBoost & SSD drives?

  • How to unlock and remove a protected partition from Prestigio USB stick?

    - by mr.b
    Ok, so, I have one of those fancy schmancy devices, which is given to me by a frustrated friend of mine. Device is a Prestigio Leather 8GB, which identifies itself to Linux host as: Bus 001 Device 006: ID 1307:0165 Transcend Information, Inc. 2GB/4GB Flash Drive Kernel messages as USB device is plugged in: kernel: [ 2769.580042] usb 1-9: new high speed USB device using ehci_hcd and address 7 kernel: [ 2769.714782] scsi8 : usb-storage 1-9:1.0 kernel: [ 2770.713937] scsi 8:0:0:0: Direct-Access 8192MB flash drive 1.00 PQ: 0 ANSI: 2 kernel: [ 2770.714535] scsi 8:0:0:1: Direct-Access 8192MB flash drive 1.00 PQ: 0 ANSI: 2 kernel: [ 2770.715734] sd 8:0:0:0: Attached scsi generic sg3 type 0 kernel: [ 2770.716108] sd 8:0:0:1: Attached scsi generic sg4 type 0 kernel: [ 2770.722175] sd 8:0:0:0: [sdc] 962560 512-byte logical blocks: (492 MB/470 MiB) kernel: [ 2770.722657] sd 8:0:0:0: [sdc] Write Protect is on kernel: [ 2770.731078] sd 8:0:0:1: [sdd] 14012416 512-byte logical blocks: (7.17 GB/6.68 GiB) kernel: [ 2770.731215] sdc: kernel: [ 2770.738251] sd 8:0:0:1: [sdd] Write Protect is off kernel: [ 2770.880328] kernel: [ 2770.885876] sd 8:0:0:0: [sdc] Attached SCSI removable disk kernel: [ 2770.887442] sdd: unknown partition table kernel: [ 2771.049605] sd 8:0:0:1: [sdd] Attached SCSI removable disk So, symptoms are typical for U3-like devices: two separate devices inside of a single flash device. Windows sees it also as two identical usb devices, and mounts two separate drives to system, whereas first one presents itself as a CDROM device, holding a write-protected content, and second is a regular flash-disk partition, that "can" be written to. However, it seems like it's broken in some weird way, since it won't let me write anything to it, format it, nothing, but that's not the issue right now. Question: How can I unlock entire USB stick so it appears to system as a single, 8GB device which can be partitioned and used normally, without restrictions? Since it appeared to be an U3 device, I have tried standard utilities: both U3 Uninstaller by u3.com (found on SoftPedia), and opensource u3_tool from sourceforge (on both Windows and Linux). First utility failed to even detect USB stick as U3 device (simply stood idle while I re-plugged stick several times), while second tool failed with some obscure error about SCSI command unable to do something (I might be able to provide exact errors when I switch back to windows). u3_tool -i /dev/sg3 (Display device info) fails with u3_partition_info() failed: Device reported command failed: status 1 ...and every other option fails with same error, minus first part which states which command precisely has failed. So, apparently, this isn't a U3 device. Or, if it is, it doesn't behave like one. I read on a few occasions that this device protection is done by special command sent to device which tells it to lock itself, and so there should be an unlock command, that would set drive straight. Does anyone have any idea about what could I do to this device to fix it? P.S. I also mentioned a problem with being unable to use second "drive", but I'll tackle that problem when (and if) I manage to merge those two devices into one...

  • Remote Debian System Preventing Logon

    - by choobablue
    I have a dozen or so single board computers on a network running Debian (squeeze) and access them via ssh (ssh server is dropbear). To give an idea of the hardware of these computers they're 1.2 GHz x86 processors, 1GB of RAM and 4GB flash drives formatted as ext2 (I avoided ext3 to prevent the added flash write stress from journaling), there is also a swap partition on the drive. Normally the setup I'm using works great and I can access all the computers. Every once in a while one will prevent access. What happens is I try to connect via ssh (putty) and it gives me the login prompt, I enter the username and password and it responds 'Access Denied' and it will also refuse any public key in ~/.ssh/authorized_keys. The credentials are correct as they worked previously. The computer responds to pings and putty recognizes the server public key, which implies to me the system is still running. Restarting the server fixes the problem and I can log in again. (I tried a temporary fix of putting shutdown -r now in the root crontab but this doesn't seem to reliably be run once the hang happens) Once I restart however there doesn't seem to be any information in any of the system logs to indicate what happened, the logs are simply empty for that time period, as if the system had crashed. There is some custom software running on the system which appears to stop working (which is why I wanted to ssh to begin with). I'm assuming that this program is the source of the problems but I'm unsure of how it would cause it and how to debug what is happening. The most likely explanation I can think of is that there is a memory leak in the other program that then prevents dropbear from spawning a new login shell (and crontab from executing shutdown) as there is not enough free memory. But looking at memory usage of the other (working) computers there doesn't seem to be any meaningful increase in memory to indicate a leak (unless it's a very big, fast acting and rare leak). I would think that when the OS ran out of memory it would restart the system or kill processes (the Linux kernel restarts right?). The other thing I wonder about is if the fact that they are running off a flash drive could have some effect, especially the swap partition (which I think I should remove to prevent wear of the flash), but the flash drives are young (~1 month) and I don't think that wear would be a factor yet. Does anybody have an idea of what could cause these symptoms, if it could be done by a memory leak, or something else I haven't thought of. And does anybody know of a method to try to debug the problem and find out more information about what's going wrong?
