  • Symfony 1.4: Custom error message for CSRF in forms

    - by Tom
    Hi, Can anyone tell me where/how to customise the CSRF token error message for forms in Symfony 1.4. I'm using sfDoctrineGuard for logins and in this form particularly, whenever a session runs out and you still have the page open, it throws a very user-unfriendly error: "CSRF attack detected". Something like "This session has expired. Please return to the home page and try again" sounds better. What's the right way to do this in the form class? Thanks.

  • How to Solve N-Queens Problem in Scheme?

    - by Philip
    Hi, I'm stuck on the extended exercise 28.2 of How to Design Programs. Here is the link to the question: http://www.htdp.org/2003-09-26/Book/curriculum-Z-H-35.html#node_chap_28 I used a vector of true or false values to represent the board instead of using a list. This is what I've got which doesn't work: #lang Scheme (define-struct posn (i j)) ;takes in a position in i, j form and a board and returns a natural number that represents the position in index form ;example for board xxx ; xxx ; xxx ;(0, 1) - 1 ;(2, 1) - 7 (define (board-ref a-posn a-board) (+ (* (sqrt (vector-length a-board)) (posn-i a-posn)) (posn-j a-posn))) ;reverse of the above function ;1 - (0, 1) ;7 - (2, 1) (define (get-posn n a-board) (local ((define board-length (sqrt (vector-length a-board)))) (make-posn (floor (/ n board-length)) (remainder n board-length)))) ;determines if posn1 threatens posn2 ;true if they are on the same row/column/diagonal (define (threatened? posn1 posn2) (cond ((= (posn-i posn1) (posn-i posn2)) #t) ((= (posn-j posn1) (posn-j posn2)) #t) ((= (abs (- (posn-i posn1) (posn-i posn2))) (abs (- (posn-j posn1) (posn-j posn2)))) #t) (else #f))) ;returns a list of positions that are not threatened or occupied by queens ;basically any position with the value true (define (get-available-posn a-board) (local ((define (get-ava index) (cond ((= index (vector-length a-board)) '()) ((vector-ref a-board index) (cons index (get-ava (add1 index)))) (else (get-ava (add1 index)))))) (get-ava 0))) ;consume a position in the form of a natural number and a board ;returns a board after placing a queen on the position of the board (define (place n a-board) (local ((define (foo x) (cond ((not (board-ref (get-posn x a-board) a-board)) #f) ((threatened?

  • ModelMultipleChoiceField and reverse()

    - by celopes
    I have a form containing a ModelMultipleChoiceField. Is it possible to come up with a url mapping that will capture a varying number of parameters from said ModelMultipleChoiceField? I find myself doing a reverse() call in the view passing the arguments of the form submission and realized that I don't know how to represent, in the urlconf, the multiple values from the SELECT tag rendered for the ModelMultipleChoiceField...

  • Zend Framework + Uplodify Flash Uploader Troubles

    - by Richard Knop
    I've been trying to get the Uploadify flash uploader (www.uploadify.com) to work with Zend Framework, with no success so far. I have placed all Uploadify files under /public/flash-uploader directory. In the controller I include all required files and libraries like this: $this->view->headScript()->appendFile('/js/jquery-1.3.2.min.js'); $this->view->headLink()->appendStylesheet('/flash-uploader/css/default.css'); $this->view->headLink()->appendStylesheet('/flash-uploader/css/uploadify.css'); $this->view->headScript()->appendFile('/flash-uploader/scripts/swfobject.js'); $this->view->headScript()->appendFile('/flash-uploader/scripts/jquery.uploadify.v2.1.0.min.js'); And then I activate the plugin like this (#photo is id of the input file field): $(document).ready(function() { $("#photo").uploadify({ 'uploader' : '/flash-uploader/scripts/uploadify.swf', 'script' : 'my-account/flash-upload', 'cancelImg' : '/flash-uploader/cancel.png', 'folder' : 'uploads/tmp', 'queueID' : 'fileQueue', 'auto' : true, 'multi' : true, 'sizeLimit' : 2097152 }); }); As you can see I am targeting the my-account/flash-upload script as a backend processing (my-account is a controller, flash-upload is an action). My form markup looks like this: <form enctype="multipart/form-data" method="post" action="/my-account/upload-public-photo"><ol> <li><label for="photo" class="optional">File Queue<div id="fileQueue"></div></label> <input type="hidden" name="MAX_FILE_SIZE" value="31457280" id="MAX_FILE_SIZE" /> <input type="file" name="photo" id="photo" class="input-file" /></li> <li><div class="button"> <input type="submit" name="upload_public_photo" id="upload_public_photo" value="Save" class="input-submit" /></div></li></ol></form> And yet it's not working. The browse button doesn't even show up as in the demo page, I get only a regular input file field. Any ideas where could the problem be? I've already been staring into the code for hours and I cannot see any mistake anywhere and I'm starting to be exhausted after going through the same 30 lines of code 30 times in a row.

  • Jquery flowplayer - tabs - content inside div tags not displaying

    - by Gublooo
    Hey guys, I'm looking for a simple example of JQuery tabs in which I am planning to show two different forms. I came across this example http://flowplayer.org/tools/demos/tabs/index.htm which is perfect for my needs. So I implemented the simple example. The code in question is: <div class="panes" <divFirst tab content. Tab contents are called "panes"</div <divSecond tab content</div <divThird tab content</div </div Now my content for the first tab is a form which has several of its own div tags - when I put that form with div tags as the content for the first tab - nothing appears. So I made a simple change and added another div tag to the content of the first tab as shown below and still nothing appears: <div class="panes" <div<divFirst tab content. Tab contents are called "panes"</div</div <divSecond tab content</div <divThird tab content</div </div Is there a simple way to fix this. This is the content that I want to display in my first tab - Thanks for your help <div id="formbox" class="formbox" <form id="shopping_form" method="post" <div id="3" style="width:520px;" <textarea id="message" name="message" rows="3" cols="50"</textarea </div <div id="store_row" style="width:220px;float:left;padding-bottom:10px;"<bStore</b <input type="text" id="store" name="store" class="required" size="20" / <input type="hidden" id="store_id"/ </div <div id="city_column" style="width:200px;float:left;padding-bottom:10px;"<bCity</b <input type="text" id="city" name="city" size="15"/ </div <div id="findbutton_column" style="vertical-align:top;width:80px;float:left;" <input class="find_address" id="findaddress" type="button" value="Find Store"/ </div <div id="googlerow" style="width:120px;float:left;padding-bottom:10px;" <bSelect Store</b<select id="google_stores" name="google_stores"</select <input type="hidden" id="google_address"/ </div <div id="google_message" style="float:left;padding-bottom:10px;display:none;"</div <div id="locationrow" style="float:left;padding-bottom:10px;display:none;" <bAddress/Country</b <input type="text" id="address" name="address" size="20" / <input type="text" id="country" name="country" size="20"/ </div <div style="width:520px;float:left;padding-bottom:10px;" <bPrice    <input type="text" id="price" name="price" size="20" / </div <div id="buttonrow" style="width:200px;float:right;display:none;" <input id="it" type="image" src="http://images.pe.com.s3.amazonaws.com/it.png" height="35px"/ </div </form </div

  • Does writing data to server using Java URL class require response from server?

    - by gigadot
    I am trying to upload files using Java URL class and I have found a previous question on stack-overflow which explains very well about the details, so I try to follow it. And below is my code adopted from the sniplet given in the answer. My problem is that if I don't make a call to one of connection.getResponseCode() or connection.getInputStream() or connection.getResponseMessage() or anything which is related to reponse from the server, the request will never be sent to server. Why do I need to do this? Or is there any way to write the data without getting the response? P.S. I have developed a server-side uploading servlet which accepts multipart/form-data and save it to files using FileUpload. It is stable and definitely working without any problem so this is not where my problem is generated. import java.io.Closeable; import java.io.File; import java.io.FileInputStream; import java.io.IOException; import java.io.OutputStream; import java.io.PrintWriter; import java.net.HttpURLConnection; import java.net.URL; import org.apache.commons.io.IOUtils; public class URLUploader { public static void closeQuietly(Closeable... objs) { for (Closeable closeable : objs) { IOUtils.closeQuietly(closeable); } } public static void main(String[] args) throws IOException { File textFile = new File("D:\\file.zip"); String boundary = Long.toHexString(System.currentTimeMillis()); // Just generate some unique random value. HttpURLConnection connection = (HttpURLConnection) new URL("http://localhost:8080/upslet/upload").openConnection(); connection.setDoOutput(true); connection.setRequestProperty("Content-Type", "multipart/form-data; boundary=" + boundary); OutputStream output = output = connection.getOutputStream(); PrintWriter writer = writer = new PrintWriter(output, true); // Send text file. writer.println("--" + boundary); writer.println("Content-Disposition: form-data; name=\"file1\"; filename=\"" + textFile.getName() + "\""); writer.println("Content-Type: application/octet-stream"); FileInputStream fin = new FileInputStream(textFile); writer.println(); IOUtils.copy(fin, output); writer.println(); // End of multipart/form-data. writer.println("--" + boundary + "--"); output.flush(); closeQuietly(fin, writer, output); // Above request will never be sent if .getInputStream() or .getResponseCode() or .getResponseMessage() does not get called. connection.getResponseCode(); } }

  • Django forms "not" using forms from models

    - by zubinmehta
    I have a form generated from various models and the various values filled go and sit in some other table. Hence, in this case I haven't used the inbuilt Django forms(i.e. I am not creating forms from models ). Now the data which is posted from the self made form is handled by view1 which should clean the data accordingly. How do I go about it and use the various functions clean and define validation errors (and preferably not do validation logic in the view itself!)

  • Filter chain halted as [:login_required] rendered_or_redirected

    - by Magicked
    Hopefully I can explain this well enough, but please let me know if more information is needed! I'm building a form where a user can create an "incident". This incident has the following relationships: belongs_to: customer (customer has_many incidents) belongs_to: user (user has_many incidents) has_one: incident_status (incident_status belongs to incident) The form allows the user to assign the incident to a user (select form) and then select an incident status. The incident is nested in customer. However, I'm getting the following in the server logs: Processing IncidentsController#create (for 127.0.0.1 at 2010-04-26 10:41:33) [POST] Parameters: {"commit"=>"Create", "action"=>"create", "authenticity_token"=>"YhW++vd/dnLoNV/DSl1DULcaWq/RwP7jvLOVx9jQblA=", "customer_id"=>"4", "controller"=>"incidents", "incident"=>{"title"=>"Some Bad Incident", "incident_status_id"=>"1", "user_id"=>"2", "other_name"=>"SS01-042310-001"}} User Load (0.3ms) SELECT * FROM "users" WHERE ("users"."id" = 2) LIMIT 1 Redirected to http://localhost:3000/session/new Filter chain halted as [:login_required] rendered_or_redirected. Completed in 55ms (DB: 0) | 302 Found [http://localhost/customers/4/incidents] It looks to me like it's trying to gather information about the user, even though it already has the id (which is all it needs to create the incident), and the user may not have permission to do a select statement like that? I'm rather confused. Here is the relevant (I think) information in the Incident controller. before_filter :login_required, :get_customer def new @incident = @customer.incidents.build @users = @customer.users @statuses = IncidentStatus.find(:all) respond_to do |format| format.html # new.html.erb format.xml { render :xml => @incident } end end def create @incident = @customer.incidents.build(params[:incident]) respond_to do |format| if @incident.save flash[:notice] = 'Incident was successfully created.' format.html { redirect_to(@incident) } format.xml { render :xml => @incident, :status => :created, :location => @incident } else format.html { render :action => "new" } format.xml { render :xml => @incident.errors, :status => :unprocessable_entity } end end end Just as an FYI, I am using the restful_authentication plugin. So in summary, when I submit the incident creation form, it does not save the incident because it halts. I'm still very new to rails, so my skill at diagnosing problems like this is still very bad. I'm going in circles. :) Thanks in advance for any help. Please let me know if more information is needed and I'll edit it in!

  • Keep username in username field when incorrect password (php)

    - by Jonathan
    How do many of the websites that have logins keep the username in the username field when the password is entered incorrectly. The form's action (it is on index.php) is another php file, which if the password is incorrect uses Header() to go back to the index and passes the error to it using GET. I could use GET to pass the username back to the form but this seems messy, and I have noticed that websites like SMF forums have the username stay in the username field without a messy URL.

  • Django: How to get current user in admin forms

    - by lazerscience
    In Django's ModelAdmin I need to display forms customized according to the permissions an user has. Is there a way of getting the current user object into the form class, so that i can customize the form in its __init__ method? I think saving the current request in a thread local would be a possibility but this would be my last resort think I'm thinking it is a bad design approach....
