  • Disabling javascript in specific block/div (containing suspect HTML) ?

    - by T4NK3R
    Is it, in any way, possible to disable the browsers execution of script inside a block/section/element ? My scenario is, that I'm letting my (future) users create "rich content" (using CK-editor). Content that wil later be shown to other users - with all the dangers that imply: xss, redirection, identity theft, spam and what not... I've, more or less, given up on trying to "sanitize" the incomming XHTML, after seeing how many known "vectors of attack" there are: http://ha.ckers.org/xss.html What I'm really looking for is something like: < div id="userContent"< scriptOFF suspect HTML < /scriptOFF< /div

  • need help with acts_as_ferret and will_paginate to play nice together

    - by ironmantis7x
    I have installed will_paginate and acts_as_ferret on my system for ruby rails. My paginate seems to work fine before installing acts_as_ferret. When I put in the code to do searching I get the following error: NoMethodError in Community#search Showing app/views/community/_result_summary.rhtml where line #3 raised: undefined method `total_entries' for []:Array Extracted source (around line #3): 1: <% if @users %> 2: <p> 3: Found <%= pluralize(@users.total_entries, "match") %>. 4: </p> 5: <% end %> If I take out the search function, paginate works but it's pointless because I can't do searches. Can any one help me out on this one?? Thanks!! Stephen

  • App logicstics & changes due to scope creep

    - by Kevin Brown
    I started an app that was initially a testing platform--user management, and managers that can view their employees tests. Recently, functionality has been extended (not built yet) to allow users to complete a test in place of an employee--basically adding a record, but no user. I have three tables in use for this: users(contains user info for login/security), profiles (all personal info: address, height, etc.), and survey (contains survey answers for user). How do I extend my application to encompass this functionality with minimal change to the structure? I assume that the best way to do this would be to insert records to the tables profiles and survey, and have no username/password/email? There MUST be a user_id associated b/c the tables are linked through the user_ids...

    - by Catarrunas
    Hello, im building a asp.net web site with 2.0 framework. I've been "fighting" with web.config, i've changed it quiet some times. So to start from scracht this is what i have: <?xml version="1.0" encoding="utf-16"?> <configuration> <connectionStrings> <remove name="LocalSqlServer"/> <add name="ABC" connectionString="Database=jsilvaqqc.mdf; Data Source=213.175.208.3;Initial Catalog=jsilvaqqc;User ID=jsilva;Password=joao123#;" providerName="System.Data.SqlClient"/> <add name="LocalSqlServer" connectionString="Database=jsilvaqqc.mdf; Data Source=213.175.208.3;Initial Catalog=jsilvaqqc;User ID=jsilva;Password=joao123#;" providerName="System.Data.SqlClient"/> </connectionStrings> <location path="Members"> <system.web> <authorization> <allow users="*"/> <deny users="?"/> </authorization> </system.web> </location> <system.web> <compilation debug="true"/> </system.web></configuration> It works fine im my machine.

  • database vs flat file, which is a faster structure for regex matching with many simultaneous request

    - by Jamex
    Hi, which structure returns faster result and/or less taxing on the host server, flat file or database (mysql)? Assume many users (100 users) are simultaneously query the file/db. Searches involve pattern matching using regex against a static file/db. File has 50,000 unique lines (same data type). There could be many matches. There is no writing to the file/db, just read. Is it possible to have a duplicate the file/db and write a logic switch to use the backup file/db if the main file is in use? Which language is best for the type of structure? Perl for flat and PHP for db? TIA

  • Carrierwave upload to a tmp dir before saving to database

    - by user827570
    I'm trying to build a visual editor where users can click an image they are presented with an image upload form once the upload is done I use ajax to return the image and insert it back into the page. But the above method inserts the image straight into the database but I want users to be able to visualize the image before the image is inserted into the database. So I was wondering if the image using carrierwave could be uploaded to a temp location, sent back to the user and then when the user saves the page the image is moved into the permanent location. Here's what I have so far. def edit_image @page = Page.find(1) @page.update_attributes(params[:page]) @page.save return :text => @page.file end But this is what I want to achieve def temp_image #uploads received image to a temp location #returns image to the user end And once the user clicks save def save #moves the file in the temp folder to the permanent location end Cheers

  • Multitenant shared user account?

    - by jpartogi
    Dear all, Based on your experience, which is the route to go for a multi-tenant user login? One user login per account. Which means if there is one user that has access to multiple account, there will be redundancy of record in the database One user login for all account that she has privileges to. Which means one user record has access to multiple account if she has privileges to that account. From your experience, which one is better and why? I was thinking to choose the latter, but I don't know whether it will cause security issue or less flexibility. Thank you for sharing your experience.

  • Using thrift to mix development languages

    - by christopher-mccann
    I am currently developing an application which will require multiple different development languages. I want to use PHP as the final piece of the puzzle - the physical web page construction. This PHP web app will need to contact multiple web services which could be coded in anything from Java to Erlang to Python. Each of these web services will be implemented with an API. My plan is to use Thrift to allow this mix to work. Is this the correct approach or am I mixing up what the whole point of Thrift is?

  • [C#] How to consume web service adheres to the Event-based Asynchronous Pattern?

    - by codemonkie
    I am following the example from http://msdn.microsoft.com/en-us/library/8wy069k1.aspx to consume a web service implemented (by 3rd party) using the Event-based Asynchronous Pattern. However, my program needs to do multiple calls to the DoStuffAsync() hence will get back as many DoStuffCompleted. I chose the overload which takes an extra parameter - Object userState to distinguish them. My first question is: Is it valid to cast a GUID to Object as below, where GUID is used to generate unique taskID? Object userState = Guid.NewGuid(); Secondly, do I need to spawn off a new thread for each DoStuffAsync() call, since I am calling it multiple times? Also, would be nice to have some online examples or tutorials on this subject. (I've been googling for it the whole day and didn't get much back) Many thanks

  • Script to Copy User according to UID

    - by bradlis7
    I'm looking for a way to copy all non-system users from one PC to another. I can get the group and passwd files copied over using this awk -F":" ' $3 > 499 ' etc/passwd >> /etc/passwd awk -F":" ' $3 > 499 ' etc/group >> /etc/group But, how would I go about getting the shadow file copied over since it does not store the UID? Assume that there are over 1000 users, so doing a grep with the usernames, such as egrep '(bob|bill|sarah|sal):' etc/shadow >> /etc/shadow generating the usernames from the awk code above, would be a bit inefficient, but a possible option.

  • Starting with asp.net MVC

    - by Josemalive
    Hello, Actually im doing a home page that only have an action called Index() that returns the view Index.ascx. This index page will be composed by lastest news and lastest registered users, i think that create two partial views is the best idea (this way i could use it in other views). for other hand i have a data access class that calls to database for get stuff (get last news, get last users, etc...) My question is simple, should i call to the this data access class in the Index() action of my HomeController, and add to the ViewData the data obtained? I think that this index() action shouldnt be the responsable of passing this data to the partial views, right? Could you give me a hand? im messing too much? ;-) Thanks in advance. Best Regards. Jose

  • Is this a "valid" css image replacement technique?

    - by user278457
    I just came up with this, it seems to work in all modern browsers, I just tested it then on (IE8/compatibility, Chrome, Safari, Moz) HTML <img id="my_image" alt="my text" src="images/small_transparent.gif" /> CSS #my_image{ background-image:url('images/my_image.png'); width:100px; height:100px;} Pro's: image alt text is best-practice for accessibility/seo no extra HTML markup, and the css is pretty minimal too gets around the css on/images off issue where "text-indent" techniques hide text from low bandwidth users The biggest disadvantage that I can think of is the css off/images on situation, because you'll only send a transparent gif. I'd like to know, who uses images without stylesheets? some kind of mobile phone or something? I'm making some sites for clients in regional Australia (hundreds of km from the nearest city), where many users will be suffering from dial-up connections, and often outdated browsers too, so the "images off" issue is an important consideration. are there any other side effects with this technique that I haven't considered?

  • Chrome Extension Manifest 'Matches'

    - by Aristotle
    I'm trying my hands at a simple Chrome Extension, but am running into a problem with providing a value for the matches array in my content_scripts. { "name": "My Extension", "version": "1.0", "description": "My Extension Experiment", "browser_action": { "default_icon": "icon.png", "default_title": "Ext", "default_popup": "popup.html" }, "content_scripts": { "matches": ["http://*"], "js": ["scripts.js"] } } When I try to load this extension into Chrome, I get the following message: Could not load extension from 'C:\Users\foo\Desktop\Extensions\bar'.Invalid value for 'content_scripts'. I cannot see what is "invalid" about my value though. What I'm trying to do is match every URL, so my extension can manipulate the DOM (via javascript within scripts.js) of any page it is ran on. Am I missing something, going about this all wrong, or what? update After posting this question, I did notice that the Google example was slightly different than mine, so I modified my code a bit to reflect their syntax: "content_scripts": [{ "matches": ["http://*"], "js": ["scripts.js"] }] That being said, I still get the following error when trying to load my extension: Could not load extension from 'C:\Users\foo\Desktop\Extensions\bar'. Invalid value for 'content_scripts[0].matches[0]'.

    Hi Guys I am trying to create a web app to share docs with all editor features (just like google docs). My main requirements for this app are as follows: 1. Should have all editor features (can be done using open office api, google docs api, Microsoft office web apps api) 2.

Can save the document created and edited on my own/ custom server addr. (Which api can support this??? I know open office can support this) Guys can you please suggest me one api which can be used to do all the above.

  • PHP - Loop thru recordset and fire event each n rows

    - by Luciano
    I'm looking for the right logic to loop thru a recordset and fire an event each n times. Searching on Google i've found some discussion on similar situations, but it seems that solutions don't fits my needs. Let's say i have a recordset of 22 rows. I want to loop thru each row and launch a function on the 4th, the 8th, the 12th and so on... Using the modulus operator as shown in this answer, if($i % 4 == 0), i get the event fired each 4 rows, but 22 its not a multiple of 4 so the event is fired till the 20th row and then nothing. Maybe i need to make a division counting rows in 'excess'? Since the recordset will be between 50 and 200 rows i think its not necessary run multiple query of 4 rows, am I wrong? Thanks in advance!

  • Marionette multi user/roles application

    - by Fabrizio Fortino
    I have to build a pretty complex application using Backbone Marionette. The user interface has to handle multiple users with different roles. For example the 'admin' user will see the complete menu whereas the 'guest' user will access a subset of the same menu. Moreover some views will be accessible to all the users but the functions inside them (add, edit, delete) need to be profiled on the different roles. I am not sure about the right approach to use in order to solve this issue. I could have different templates for the different roles but in this case plenty of code will be duplicated inside them. Is there any best practice (or maybe some example) to sort my problem out using Marionette? Thanks in advance, Fabrizio

  • How to implement Auto_Increment per User, on the same table?

    - by Jonas
    I would like to have multiple users that share the same tables in the database, but have one auto_increment value per user. I will use an embedded database, JavaDB and as what I know it doesn't support this functionality. How can I implement it? Should I implement a trigger on inserts that lookup the users last inserted row, and then add one, or are there any better alternative? Or is it better to implement this in the application code? Or is this just a bad idea? I think this is easier to maintain than creating new tables for every user. Example: table +----+-------------+---------+------+ | ID | ID_PER_USER | USER_ID | DATA | +----+-------------+---------+------+ | 1 | 1 | 2 | 3454 | | 2 | 2 | 2 | 6567 | | 3 | 1 | 3 | 6788 | | 4 | 3 | 2 | 1133 | | 5 | 4 | 2 | 4534 | | 6 | 2 | 3 | 4366 | | 7 | 3 | 3 | 7887 | +----+-------------+---------+------+ SELECT * FROM table WHERE USER_ID = 3 +----+-------------+---------+------+ | ID | ID_PER_USER | USER_ID | DATA | +----+-------------+---------+------+ | 3 | 1 | 3 | 6788 | | 6 | 2 | 3 | 4366 | | 7 | 3 | 3 | 7887 | +----+-------------+---------+------+ SELECT * FROM table WHERE USER_ID = 2 +----+-------------+---------+------+ | ID | ID_PER_USER | USER_ID | DATA | +----+-------------+---------+------+ | 1 | 1 | 2 | 3454 | | 2 | 2 | 2 | 6567 | | 4 | 3 | 2 | 1133 | | 5 | 4 | 2 | 4534 | +----+-------------+---------+------+
