• Web framework recommendation for python (webservices, auth, cache, ...)

  - by illuminated

  Hi all, Googling for the past week, but cannot finally decide which python web framework would be right for me. The web app I'm about to develop would be almost completely "pure" html with js (jQuery). Server side would have to do the following: authentication session management caching web services (almost all the on page data would be pulled with jQuery through web services) secured web services (through some form of authentication; this is for remote accessing some of the web services though other web apps, desktop/mobile applications) If there is a good tutorial/guide/idea for how to do this in Django I would be most thankfull if someone could share it as I already have experience with it. The thing that made me start thinking about other frameworks is Django's built in ORM. I know I could swap it with SQLAlchemy, but wouldn't go down that road if I'm not sure all the rest of the requirements is supported. Thanks all in advance.

• Hibernate object equality checking

  - by Sujee

  As far as I understand(correct me if I am wrong) Hibernate uses object reference to check the object equality. When Hibernate identifies that there are more than one objects attached to same DB record, it throws following exception. "a different object with the same identifier value was already associated with the session" My question is, does Hibernate use equal() method to check the object equality (The default equal method uses object reference)? If it is true, will overridden equal() method change the Hibernate behavior? Note: My question is not about the issues of implementing equal() or hashCode() methods in a Hibernate persisted object. Thank you.

• CakePHP: Ajax view problem (nothing in the view showing)

  - by Adim

  I created a function in my controller called addToPlaylist($songName). I wanted to add these song names to an array and then a session variable using an Ajax call. The first time i did this i got an error saying i do not have a template file to display in the chosen div ("add_to_playlist.ctp was missing"). I created this file and everything seemed to be working correctly. Basically I went to bed woke up and it is broken (it is possible I changed something before I went to bed). The problem now is that it does not show anything when i click the ajax link. when i click on the ajax link it seems to call the function but nothing displays in the view (except debug info) even when i delete the view (add_to_playlist.ctp) i get no errors, I just see debug info now.

• Linq to NHibernate - How to include parent object and only certain child objects

  - by vakman

  Given a simplified model like the following: public class Enquiry { public virtual DateTime Created { get; set; } public virtual Sender Sender { get; set; } } public class Sender { public virtual IList<Enquiry> Enquiries { get; set; } } How can you construct a Linq to Nhibernate query such that it gives you back a list of senders and their enquiries where the enquiries meet some criteria. I have tried something like this: return session.Linq<Enquiry>() .Where(enquiry => enquiry.Created < DateTime.Now) .Select(enquiry => enquiry.Sender) In this case I get an InvalidCastException saying you can't cast type Sender to type Enquiry. Any pointers on how I can do this without using HQL?

• HQL - row identifier for pagination

  - by anna.ruk

  Does anyone know if HQL has a keyword to identify rows such as ROWID or ROWNUM? I would like to implement pagination with HQL but I am not able to use .setMaxResult() or .setFirstResult() because I don't work with the session object directly and therefore don't use the Query object but simply create my query as a string and use the .find() method. I tried using LIMIT and OFFSET in my query, but HQL seems to be ignoring these keywords and is returning the whole result to me no matter what. I'm also not able to use Hibernate criteria because it does not have support for the "HAVING" clause that appears in my query. My last resort is to restrict the result set using the ROWNUM/ROWID keyword. Does anyone else have any other suggestions?

• jQuery-ajax call: async property is not working?

  - by user269386

  Hi, given to certain circumstances, I'm forced to keep page settings (Javascript-values) in the session and it has to be done right before leaving the page (I can't use cookies, since "pageSettings" can become quite large and localStorage is not an option yet ;) ). So this is how I tried it. However it seems that when I call the page directly again, the call of "http://blabla.com/bla" happens asynchronous, even though the async-attribute is set (I don't receive the settings of the previous call, but of the one before): $jQ(document).ready(function () { $jQ(window).unload(Main.__setSessionValues); }); var Main = { pageSettings: {}, __setSessionValues: function __setSessionValues() { $jQ.ajax({ type: "POST", async: false, url: "http://blabla.com/bla", data: { pageSettings: Object.toJSON(Main.pageSettings) } }); } }; Does anyone know what the problem might be? thanks in advance

• Oracle TIMESTAMP w/ timezone data type confusion

  - by JuiceBox1337

  When would you use TIMESTAMP w/ timezone as opposed to TIMESTAMP w/ local time zone? When data is stored in a column of data type TIMESTAMP w/ local tz, the data is normalized to the database time zone, and the time zone displacement is not stored as part of the column data. When users retrieve the data, Oracle returns it in the users' local session time zone. Isn't that much more useful? I can't think of a reason why I'd want to use TIMESTAMP w/ timezone and get back some gobble gook with a UTC offset.

• NHibernate Criteria Transform Result

  - by isuruceanu

  Hi I have an SecurityGroup entity witch has Memebers and Application properties. Application is a lookup. So securityGroups is in many-to-many relationship with User table and one-to-many with LookupApplciation (FK) Now I want to select all application linked to a specific user. I have follow criteria: public IList<LookupApplication> GetApplicationByUser(User user) { return this.Session.CreateCriteria(typeof(SecurityGroup), "sg") .CreateAlias("Members", "u") .CreateAlias("Application", "al") .Add(Restrictions.Eq("u.Id", user.Id)) .List<LookupApplication>(); } It trows an exception The value "Edi.Advance.Core.Model.Security.SecurityGroup" is not of type "Edi.Advance.Core.Model.Lookups.LookupApplication" and cannot be used in this generic collection. Parameter name: value and it is right. How can I transform the result to IList<LookupApplication>? Thanks

• help in security assignment

  - by scatman

  i have to write a program that sniffs network packets (part1-the simple part). and i have to update the program (part2) so that it will be able to terminate connections. the specific requirements are: construct raw packets by specifying data link layer and network layer information including appropriate source and destination MAC and IP addresses. These packets are intended to terminate the connection. To do so, you should used SOCK_RAW as the socket type to be able to set the header information by yourself. can anybody give me some ideas on the second part? should i hijack the session,apply a dos attack on one of the users?? all i need is some tips of how to terminate the connection. i am using c programming language. and this is a course assignment for the security course.

• Nhibernate Complex Type binding

  - by user329983

  I have two oracle user defined types: Audit_Type – A normal object with two fields a string and a number Audit_Table_Type – A table of audit_types, (an array) I have a stored procedure that takes as a parameter an Audit_Table_Type. List<Audit_Type> table = new List<Audit_Type>(); var query = session.CreateSQLQuery("call Audit_Rows(Audit_Table_Type(:table))") .SetParameterList("table", table, NHibernateUtil.Custom(typeof(AuditTypeUDT))) This is what I did intuativly created the ICompositeType and just set in a list of them in but this gives me nothing close to what I wanted. I couldn’t figure out how to bind to a table at all. I have built the inline sql that would do this for me but it would destroy my shared pool (not using binds). So a General question how do I bind to complex/composite types using Nhibernate?

• Java Security filter together with thickbox pop-ups

  - by user197127

  Hi, I have a java application that uses a security filter to protect certain resources. If there is no user logged on, it will keep in session the request path and redirect to a logon page. After a successful logon, user is redirected to the original requested page. I have now added some thickbox (ajax bases pop-up) popups to the application. Unfortunately, when I get now a popup that is "secure" the filter redirects to a logon page (which is not a popup) and makes the whole application messy. Anyone with ideas on how to solve this? Thanks

• Commenting out protect_from_forgery

  - by Andy

  Hi, I was trying to use active record store but I kept getting an invalid authenticity token. Someone told me to remove my protect_from_forgery from application controller. I know that this would remove all auth tokens but I'm not sure if this is a good idea. Does active record store not need auth tokens? By the way, all I need is a way to dynamically calculate the number of users online and their session variables. If there is a better way than using active record store it would be nice to know.

• Real time web site using PHP or ASP.NET

  - by Roman

  Hey Guys, I'm looking for a way to put real time features into my web site. The idea is asynchronous communication between 2 people - like a chat session. If I use the chat example - I'd like the second person to know that the first one has sent a message to him, without refreshing or doing something active on the web page. Polling is not a good idea here - so is there any other solution? the back-end could be ASP.NET or PHP (ASP.NET preferred). Help would be much appreciated, Thanks, Roman

• EntityManager does not update on flush()

  - by Sara

  Java EJB's EntityManager does not update data from a Consumer. A Consumer logs into a shop, buys some stuff and wants to look at his shopping-history. Everything is displayed but his last purchase. If he logs out and in, it shows. I have used JPA to persist buys/purchases (that are mapped to the Consumer)to DB. It seems like purchases from this session can't be detected. Code: public Buys buyItem(Consumer c, int amount) { Buys b = new Buys(); b.setConsumerId(c); b.setContent("DVD"); b.setPrice(amount); em.persist(b); em.flush(); return b; } public Collection getAllBuysFromUser(Consumer consumer) { Collection collection = consumer.getBuysCollection(); return collection; } Help!? Flush does not do the trick...

• Can my app arrange a gdb breakpoint or watch?

  - by Larry Gritz

  Is there a way for my code to be instrumented to insert a break point or watch on a memory location that will be honored by gdb? (And presumably have no effect when gdb is not attached.) I know how to do such things as gdb commands within the gdb session, but for certain types of debugging it would be really handy to do it "programmatically", if you know what I mean -- for example, the bug only happens with a particular circumstance, not any of the first 11,024 times the crashing routine is called, or the first 43,028,503 times that memory location is modified, so setting a simple break point on the routine or watch point on the variable is not helpful -- it's all false positives. I'm concerned mostly about Linux, but curious about if similar solutions exist for OS X (or Windows, though obviously not with gdb).

• How to execute a large PHP Script ?

  - by atif089

  Well basically I may want to execute a script that may take as much as 1 hours as well. What I really want to do is Send SMS to my users using a third party API. So its basically like I supply my script with an array of phone numbers and fire the method to send SMS. However assuming it take 5 seconds to send 1 SMS and I want to send 1000 SMS which is roughly 1 - 2 hours. I can use set_time_limit() because I am on shared host. One way to do this is store numbers in a session and execute each SMS and use javascript to refresh that page until end. This way I need to keep my browser open and the execution will stop if my Internet Connection is disconnected. So, Is there any better way to do this ? Hope I am clear enough to explain what I want? I want to execute a large script that may take hours to execute without getting timeout.

• Android: Best way/library to write an app that simply gets/sets your Facebook status, sends Facebook

  - by D.

  I have the Android Facebook-Connect library running in my emulator and I'm able to set my status with the Facebook API I have setup. However, I don't know where to go from there? Am I supposed to use the session key that this library allows me to get and make some Facebook API calls? I haven't found any code examples to even see what the proper syntax is. Am I better off using another library? I tried fbrocket with limited luck(I get a "server error 104 - Incorrect signature"). Thanks for any help.

• Client / Server security from mobile to website

  - by Amir Latif

  Hey. Am new to the world of web programming and learning a bunch of fairly simple new pieces of tech, trying to piece them all together. So, we have a simple client (currently iPhone, to move to J2ME soon) that's pulling down lists of data via PHP, which is talking to a MySQL db. I have a rudimentary user/login system so that data is only served to someone who matches a known user etc, either on the website or on the client. All the php scripts on the website that query the DB check to make sure an active session is in place, otherwise dumping the user back to the login screen. I've read a little about SSL and want to know if that is sufficient to protect the website AND the data passing between the server and the client?

• Hibernate deletion issue

  - by muffytyrone

  I'm trying to write a Java app that imports a data file. The process is as follows Create Transaction Delete all rows from datatable Load data file into datatable Commit OR Rollback if any errors were encountered. The data loaded in step 3 is mostly the same as the data deleted in step3. The deletion is performed using the following DetachedCriteria criteria = DetachedCriteria.forClass(myObject.class); List<myObject> myObjects = hibernateTemplate.findByCriteria(criteria); hibernateTemplate.deleteAll(myObjects); When I then load the datafile, i get the following exception nested exception is org.hibernate.NonUniqueObjectException: a different object with the same identifier value was already associated with the session: The whole process needs to take place in transaction. And I don't really want to have to compare the import file / data table and then perform an insert/update/delete to get them into sync. Any help would be appreciated.

• Codeigniter Form Validation - how to unset form values after success?

  - by BrynJ

  I realise this request goes against the example provided in the CI documentation (which advises a separate 'success' page view), but I would like to reutilise a given form view after a form has been successfully submitted - displaying a success message then displaying a blank form. I've tried a few ways unsuccessfully to clear the validation set values (unsetting $_POST, setting rules / fields to an empty array and rerunning validatio). I could redirect to the same page, but then I'd have to set a session variable to display a success message - which is a messy approach. Any ideas how to achieve the above?

• Servlet 3 spec and ThreadLocal

  - by mindas

  As far as I know, Servlet 3 spec introduces asynchronous processing feature. Among other things, this will mean that the same thread can and will be reused for processing another, concurrent, HTTP request(s). This isn't revolutionary, at least for people who worked with NIO before. Anyway, this leads to another important thing: no ThreadLocal variables as a temporary storage for the request data. Because if the same thread suddenly becomes the carrier thread to a different HTTP request, request-local data will be exposed to another request. All of that is my pure speculation based on reading articles, I haven't got time to play with any Servlet 3 implementations (Tomcat 7, GlassFish 3.0.X, etc.). So, the questions: Am I correct to assume that ThreadLocal will cease to be a convenient hack to keep the request data? Has anybody played with any of Servlet 3 implementations and tried using ThreadLocals to prove the above? Apart from storing data inside HTTP Session, are there any other similar easy-to-reach hacks you could possibly advise?
