  • Ruby on Rails solution for scrubbing data of WYSIWYG editor user input

    - by Jimmy
    Hey everyone, I am working on a simple blogging type ruby on rails application and I have everything working through tinyMCE for a nice WYSIWYG editor so the user can add some simple things like images/youtube videos and lists. What I am looking for is a nice solution for blacklisting certain elements to be filtered out of the data when it is displayed. So is there a solution for this available as a gem or available to download anywhere? Thanks!

  • SQL Server 2005 red herring error "The user does not have permission to perform this action"

    - by Sylvia
    We're getting the error "The user does not have permission to perform this action" during times of heavy load (regularly, when a trim job occurs). The error clears up when the service accessing sql server is restarted, so it's obviously not a real permissions problems. What kind of situations could cause an error like this, when it's not really a permissions problem? Any ideas of good places to start looking? thanks for any insights...

  • [rails] user's account backup and restore

    - by Cédric
    Hi everyone, I am currently working on a project and i would like my users to be able to backup/restore theirs accounts. I am looking for a rails plugin/gem that would easily do that, ie : current_user.backup() = backup_file current_user.restore(backup_file) = database import/replace I don't know if my question is very clear, but i would like to backup every user's related object (posts, comments, etc) and to be able to restore them from a backup file. Thanks per advance, Cédric.

  • Performance tuning of a Hibernate+Spring+MySQL project operation that stores images uploaded by user

    - by Umar
    Hi I am working on a web project that is Spring+Hibernate+MySQL based. I am stuck at a point where I have to store images uploaded by a user into the database. Although I have written some code that works well for now, but I believe that things will mess up when the project would go live. Here's my domain class that carries the image bytes: @Entity public class Picture implements java.io.Serializable{ long id; byte[] data; ... // getters and setters } And here's my controller that saves the file on submit: public class PictureUploadFormController extends AbstractBaseFormController{ ... protected ModelAndView onSubmit(HttpServletRequest request, HttpServletResponse response, Object command, BindException errors) throws Exception{ MutlipartFile file; // getting MultipartFile from the command object ... // beginning hibernate transaction ... Picture p=new Picture(); p.setData(file.getBytes()); pictureDAO.makePersistent(p); // this method simply calls getSession().saveOrUpdate(p) // committing hiernate transaction ... } ... } Obviously a bad piece of code. Is there anyway I could use InputStream or Blob to save the data, instead of first loading all the bytes from the user into the memory and then pushing them into the database? I did some research on hibernate's support for Blob, and found this in Hibernate In Action book: java.sql.Blob and java.sql.Clob are the most efficient way to handle large objects in Java. Unfortunately, an instance of Blob or Clob is only useable until the JDBC transaction completes. So if your persistent class defines a property of java.sql.Clob or java.sql.Blob (not a good idea anyway), you’ll be restricted in how instances of the class may be used. In particular, you won’t be able to use instances of that class as detached objects. Furthermore, many JDBC drivers don’t feature working support for java.sql.Blob and java.sql.Clob. Therefore, it makes more sense to map large objects using the binary or text mapping type, assuming retrieval of the entire large object into memory isn’t a performance killer. Note you can find up-to-date design patterns and tips for large object usage on the Hibernate website, with tricks for particular platforms. Now apparently the Blob cannot be used, as it is not a good idea anyway, what else could be used to improve the performance? I couldn't find any up-to-date design pattern or any useful information on Hibernate website. So any help/recommendations from stackoverflowers will be much appreciated. Thanks

  • Spark show logged in user

    - by Jose
    How do I show the username of the person logged in within a Spark View? The default MVC view engine had a Page object that you could get the info from. How would I do that in spark? I know that I could put the info into the viewdata dictionary, which is probably the best, but I don't want to have to write ViewData["User"] = myUser; before I return from EVERY action method. I'd like some feedback

  • Using the word "you" in an user manual

    - by yan bellavance
    I am writing a user manual and I have come to a discussion with a colleague. He says I cannot use the word "you" anywhere in the manual. Now I remember something about this at school but that was not for writing procedures. Also, doing some googling I observed that most tutorials where using it a lot. I would prefer using it but only if this is considered good practice. what do you think?

  • Best way to get timezone of user based on area code

    - by niyogi
    Hi folks I'm attempting to get a timezone of a user based on area code information that they provided. I discovered the following resource on maxmind: http://geolite.maxmind.com/download/geoip/api/php/timezone/ I suspect that I could use this with another api that provides the state that an area code belongs to. I'm looking for a simple REST API that provides this info - or a robust scraping routine that achieve the same results. Thanks in advance!
