• Processing file uploads before object is saved

  - by Dominic Rodger

  I've got a model like this: class Talk(BaseModel): title = models.CharField(max_length=200) mp3 = models.FileField(upload_to = u'talks/', max_length=200) seconds = models.IntegerField(blank = True, null = True) I want to validate before saving that the uploaded file is an MP3, like this: def is_mp3(path_to_file): from mutagen.mp3 import MP3 audio = MP3(path_to_file) return not audio.info.sketchy Once I'm sure I've got an MP3, I want to save the length of the talk in the seconds attribute, like this: audio = MP3(path_to_file) self.seconds = audio.info.length The problem is, before saving, the uploaded file doesn't have a path (see this ticket, closed as wontfix), so I can't process the MP3. I'd like to raise a nice validation error so that ModelForms can display a helpful error ("You idiot, you didn't upload an MP3" or something). Any idea how I can go about accessing the file before it's saved? p.s. If anyone knows a better way of validating files are MP3s I'm all ears - I also want to be able to mess around with ID3 data (set the artist, album, title and probably album art, so I need it to be processable by mutagen).

• How can I test ActiveRecord::RecordNotFound in my rails app?

  - by fursie

  Hi, I have this code in my controller and want to test this code line with a functional test. raise ActiveRecord::RecordNotFound if @post.nil? which assert method should I use? I use the built-in rails 2.3.5 test framework. I tried it with this code: test "should return 404 if page doesn't exist." do get :show, :url => ["nothing", "here"] assert_response :missing end but it doesn't work for me. Got this test output: test_should_return_404_if_page_doesn't_exist.(PageControllerTest): ActiveRecord::RecordNotFound: ActiveRecord::RecordNotFound app/controllers/page_controller.rb:7:in `show' /test/functional/page_controller_test.rb:21:in `test_should_return_404_if_page_doesn't_exist.'

• Ruby and Forking

  - by Cory

  Quick question about Ruby forking - I ran across a bit of forking code in Resque earlier that was sexy as hell but tripped me up for a few. I'm hoping for someone to give me a little more detail about what's going on here. Specifically - it would appear that forking spawns a child (expected) and kicks it straight into the 'else' side of my condition (less expected. Is that expected behavior? A Ruby idiom? My IRB hack here: def fork return true if @cant_fork begin if Kernel.respond_to?(:fork) Kernel.fork else raise NotImplementedError end rescue NotImplementedError @cant_fork = true nil end end def do_something puts "Starting do_something" if foo = fork puts "we are forking from #{Process.pid}" Process.wait else puts "no need to fork, let's get to work: #{Process.pid} under #{Process.ppid}" puts "doing it" end end do_something

• DataContext Refresh and PropertyChanging & PropertyChanged Events

  - by Scott

  I'm in a situation where I am being informed from an outside source that a particular entity has been altered outside my current datacontext. I'm able to find the entity and call refresh like so MyDataContext.Refresh(RefreshMode.OverwriteCurrentValues, myEntity); and the properties which have been altered on the entity are updated correctly. However neither of the INotifyPropertyChanging INotifyPropertyChanged appear to be raised when the refresh occurs and this leaves my UI displaying incorrect information. I'm aware that Refresh() fails to use the correct property getters and setters on the entity to raise the change notification events, but perhaps there is another way to accomplish the same thing? Am I doing something wrong? Is there a better method than Refresh? If Refresh is the only option, does anyone have a work around?

• Multiple return points in scala closure/anonymous function

  - by Debilski

  As far as I understand it, there is no way in Scala to have multiple return points in an anonymous function, i.e. someList.map((i) => { if (i%2 == 0) return i // the early return allows me to avoid the else clause doMoreStuffAndReturnSomething(i) }) raises an error: return outside method definition. (And if it weren’t to raise that, the code would not work as I’d like it to work.) One workaround I could thing of would be the following someList.map({ def f(i: Int):Int = { if (i%2 == 0) return i doMoreStuffAndReturnSomething(i) } f }) however, I’d like to know if there is another ‘accepted’ way of doing this. Maybe a possibility to go without a name for the inner function? (A use case would be to emulate some valued continue construct inside the loop.)

• Significant new inventions in computing since 1980

  - by Alan Kay

  This question arose from comments about different kinds of progress in computing over the last 50 years or so. I was asked by some of the other participants to raise it as a question to the whole forum. Basic idea here is not to bash the current state of things but to try to understand something about the progress of coming up with fundamental new ideas and principles. I claim that we need really new ideas in most areas of computing, and I would like to know of any important and powerful ones that have been done recently. If we can't really find them, then we should ask "Why?" and "What should we be doing?"

• Handle mysql restart in SQLAlchemy

  - by wRAR

  My Pylons app uses local MySQL server via SQLAlchemy and python-MySQLdb. When the server is restarted, open pooled connections are apparently closed, but the application doesn't know about this and apparently when it tries to use such connection it receives "MySQL server has gone away": File '/usr/lib/pymodules/python2.6/sqlalchemy/engine/default.py', line 277 in do_execute cursor.execute(statement, parameters) File '/usr/lib/pymodules/python2.6/MySQLdb/cursors.py', line 166 in execute self.errorhandler(self, exc, value) File '/usr/lib/pymodules/python2.6/MySQLdb/connections.py', line 35 in defaulterrorhandler raise errorclass, errorvalue OperationalError: (OperationalError) (2006, 'MySQL server has gone away') This exception is not caught anywhere so it bubbles up to the user. If I should handle this exception somewhere in my code, please show the place for such code in a Pylons WSGI app. Or maybe there is a solution in SA itself?

• Converting IPv4 or IPv6 address to a long for comparisons

  - by Justin Akehurst

  In order to check if an IPv4 or IPv6 address is within a certain range, I've got code that takes an IPv4 address, turns that into a long, then does that same conversion on the upper/lower bound of the subnet, then checks to see if the long is between those values. I'd like to be able to do the same thing for IPv6, but saw nothing in the Python 2.6 standard libraries to allow me to do this, so I wrote this up: import socket, struct from array import array def ip_address_to_long(address): ip_as_long = None try: ip_as_long = socket.ntohl(struct.unpack('L', socket.inet_pton(socket.AF_INET, address))[0]) except socket.error: # try IPv6 try: addr = array('L', struct.unpack('!4L', socket.inet_pton(socket.AF_INET6, address))) addr.reverse() ip_as_long = sum(addr[i] << (i * 32) for i in range(len(addr))) except socket.error as se: raise ValueError('Invalid address') except Exception as e: print str(e) return ip_as_long My question is: Is there a simpler way to do this that I am missing? Is there a standard library call that can do this for me?

• uWSGI loggin format unification

  - by Mediocre Gopher

  I'm attempting to unify the log format of my uwsgi instance. Currently there's three different types of log items: Sun Sep 2 17:31:00 2012 - spawned uWSGI worker 10 (pid: 2958, cores: 8) (DEBUG) 2012-09-02 17:31:01,526 - getFileKeys_rpc called Traceback (most recent call last): File "src/dispatch.py", line 13, in application obj = discovery(env) File "src/dispatch.py", line 23, in discovery ret_obj = {"return":dispatch(method,env)} File "src/dispatch.py", line 32, in dispatch raise Exception("test") Exception: test The first is an error spawned by uWSGI internally (I have the --log-date option set). The second is from the logging module, which has logging.basicConfig(format='(%(levelname)s) %(asctime)s - %(message)s') set. The final one is an uncaught exception. I understand that the uncaught exception probably can't be formatted, but is there some way of having uwsgi use the logging module for its internal logs? Or the other way around?

• Exporting query results to a file on the fly

  - by ercan

  Hi all, I need to export the results of a query to a csv file in an FTP folder. Is it possible to achieve this within a stored procedure? If yes, comes yet another constraint: can I achieve this without sysadmin privileges, aka without using xp_cmdshell + BCP utility? If no to 2., does the caller have to have sysadmin privileges or would it suffice if the SP owner has sysadmin privileges? Here are some more details to the problem: The SP must export and transfer the file on the fly and raise error if something went wrong. The caller must get a response immediately, i.e. in case of no error, he can assume that the results are successfully transferred to the folder. Therefore, a DTS/SSIS job that runs every N minutes is not an option. I know the problem smells like I will have to do this at application level, but I would be more than happy if all those stuff could be done from T-SQL.

• Django how to handle # in variable name.

  I've got a dictionary in python which is assigned as a template variable. One of the keys is named "#text" but when i try to access it using {{ artist.image.3."#text"}} I get an error which is File "/home/jack/Desktop/test/appengine/lib/django/django/template/__init__.py", line 558, in __init__ raise TemplateSyntaxError, "Could not parse the remainder: %s" % token[upto:] TemplateSyntaxError: Could not parse the remainder: "#text" So how can I use this in the template? I've tried putting quotes around it but to no avail. I'd like to not modify the dictionary if possible, but if its easy enough to do then I guess its okay. Thanks

• Why Switch/Case and not If/Else If?

  - by OB OB

  This question in mainly pointed at C/C++, but I guess other languages are relevant as well. I can't understand why is switch/case still being used instead of if/else if. It seems to me much like using goto's, and results in the same sort of messy code, while the same results could be acheived with if/else if's in a much more organized manner. Still, I see these blocks around quite often. A common place to find them is near a message-loop (WndProc...), whereas these are among the places when they raise the heaviest havoc: variables are shared along the entire block, even when not propriate (and can't be initialized inside it). Extra attention has to be put on not dropping break's, and so on... Personally, I avoid using them, and I wonder wether I'm missing something? Are they more efficient than if/else's? Are they carried on by tradition?

• How to handle security constraints using GWT 2.1's RequestFactory?

  - by Marc

  I am currently developing a GWT 2.1 application that is to be deployed on Google App Engine. I would like to realise the server communication using the new RequestFactory. Now my question is how to handle fine-grained security issues in this context? Some server actions (of those declared in the RequestContext stubs) shall be restricted to certain users (possibly depending on the parameters of the remote call). If a call is unauthorised, I would like the client to show a login page (so that one may log in as a different user, for example). From the Expenses example, I know how to implement an automatic redirection to a login page, but in this example, the security model is quite simple: A client is allowed to access the servlet if and only if a user is logged in. Shall I raise a custom UnAuthorizedException in my server-side service? Where should I intercept this exception? (Can I do this in a servlet filter like the GaeAuthFilter of the Expenses example?)

• Loading url with cyrillic symbols

  - by Ockonal

  Hi guys, I have to load some url with cyrillic symbols. My script should work with this: http://wincode.org/%D0%BF%D1%80%D0%BE%D0%B3%D1%80%D0%B0%D0%BC%D0%BC%D0%B8%D1%80%D0%BE%D0%B2%D0%B0%D0%BD%D0%B8%D0%B5/ If I'll use this in browser it would replaced into normal symbols, but urllib code fails with 404 error. How to decode correctly this url? When I'm using that url directly in code, like address = 'that address', it works perfect. But I used parsing page for getting this url. I have a list of urls which contents cyrillic. Maybe they have uncorrect encoding? Here is more code: requestData = urllib2.Request( %SOME_ADDRESS%, None, {"User-Agent": user_agent}) requestHandler = pageHandler.open(requestData) pageData = requestHandler.read().decode('utf-8') soupHandler = BeautifulSoup(pageData) topicLinks = [] for postBlock in soupHandler.findAll('a', href=re.compile('%SOME_REGEXP%')): topicLinks.append(postBlock['href']) postAddress = choice(topicLinks) postRequestData = urllib2.Request(postAddress, None, {"User-Agent": user_agent}) postHandler = pageHandler.open(postRequestData) postData = postHandler.read() File "/usr/lib/python2.6/urllib2.py", line 518, in http_error_default raise HTTPError(req.get_full_url(), code, msg, hdrs, fp) urllib2.HTTPError: HTTP Error 404: Not Found

• CakePHP. How can i make a model test in a table with another primary key?

  I have this table CREATE TABLE myexamples.problems ( id INT, name VARCHAR(45) NULL , pk_id INT AUTO_INCREMENT PRIMARY KEY ); But when I try test a model in cakephp, it fails because the table has two autoincrement attributes.

• Why can't I retrieve the entities I've just persisted?

  - by felipecao

  I've got this web service that basically queries the database and returns all persisted entities. For testing purposes, I've created a TestDataManager that persists 2 example entities after Spring context is loaded (BTW, I'm using JAX-WS, Spring, Hibernate and HSQLDB). My TestDataManager looks like this: @Component public class TestDataManager { @Resource private SessionFactory sf; @PostConstruct @Transactional(readOnly = false, propagation = Propagation.REQUIRES_NEW) public void insertTestData(){ sf.openSession(); sf.openSession().beginTransaction(); sf.openSession().persist(new Site("site one")); sf.openSession().persist(new Site("site two")); sf.openSession().flush(); } } My JAX-WS endpoint looks like this: @WebService public class SmartBrickEndpoint { @Resource private WebServiceContext context; public Set<Site> getSitesForUser(String user){ return getSiteService().findByUser(new User(user)); } private ISiteService getSiteService(){ ServletContext servletContext = (ServletContext) context.getMessageContext().get("javax.xml.ws.servlet.context"); return (ISiteService) BeanRetriever.getBean(servletContext, ISiteService.class); } } This my Service class: @Component @Transactional(readOnly = true) public class SiteService implements ISiteService { @Resource private ISiteDao siteDao; @Override public Set<Site> findByUser(User user) { return siteDao.findByUser(user); } } This is my DAO: @Component @Transactional(readOnly = true) public class SiteDao implements ISiteDao { @Resource private SessionFactory sessionFactory; @Override public Set<Site> findByUser(User user) { Set<Site> sites = new LinkedHashSet<Site>(sessionFactory.getCurrentSession().createCriteria(Site.class).list()); return sites; } } This is my applicationContext.xml: <context:annotation-config /> <context:component-scan base-package="br.unirio.wsimxp.dao"/> <context:component-scan base-package="br.unirio.wsimxp.service"/> <context:component-scan base-package="br.unirio.wsimxp.spring"/> <bean id="applicationDS" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="org.hsqldb.jdbcDriver"/> <property name="url" value="jdbc:hsqldb:file:sites"/> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> <property name="dataSource" ref="applicationDS" /> <property name="configLocation"> <value>classpath:hibernate.cfg.xml</value> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.HSQLDialect</prop> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.format_sql">true</prop> <prop key="hibernate.connection.release_mode">on_close</prop> <!--<prop key="hibernate.current_session_context_class">thread</prop>--> <prop key="hibernate.query.factory_class">org.hibernate.hql.classic.ClassicQueryTranslatorFactory</prop> <prop key="hibernate.hbm2ddl.auto">create-drop</prop> </props> </property> </bean> <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean> <tx:annotation-driven transaction-manager="transactionManager" /> This is what's going on now: when the app is deployed, TestDataManager#insertTestData kicks-in (due to @PostConstruct) and persist does not raise any exception. I should have 2 entities in the DB by now. Afterwards, I invoke the endpoint by a SOAP client, and the request goes all the way up to the DAO. The Hibernate invocation does not raise any exception, but the returned list is empty. The odd thing is, in TestDataManager, if I switch from sf.openSession() to sf.getCurrentSession(), I get an error message: "No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here". What I am doing wrong here? Why is the query "not seeing" the persisted entities? Why do I need to invoke sf.openSession() on TestDataManager although it's annotated with @Transactional? I have done some tests with hibernate.current_session_context_class=thread in application.xml, but then I just switch problems in each class. I'd like not needing to manually invoke sf.openSession() and leave that for Hibernate to take care. Thanks a lot for any help!

• Pear MDB2 class and raiserror exceptions in SQL Server

  Hi, in SQL Server it's possible to raise an error with raiserror(). I want to use a severity, which doesn't interrupt the connection. This error is raised in a stored procedure. In SQL Management Studio all is fine and I get my error code when executing this SP. But when trying to execute this SP via MDB2 in PHP5 this doesn't work. All I get is an empty array. MDB2 object is created via (including needed options): $db =& MDB2::connect($dsn); $db->setFetchMode(MDB2_FETCHMODE_ASSOC); $db->setOption('portability',MDB2_PORTABILITY_ALL ^ MDB2_PORTABILITY_EMPTY_TO_NULL); The following works (I get a PEAR error): $db->query("RAISERROR('test',11,0);"); But when calling a stored procedure which raises this error via $db->query("EXEC sp_raise_error"); there is not output. What's wrong?

  my view generates keys in this format ["job_id:1234567890", 1271430291000] where the first key element is a unique key and the second is a timestamp in milliseconds. I run my view with this elapsed_time?startkey=["123"]&endkey=["123",{}]&group=true&group_level=1 and here is my reduce function, the intention is to reduce the output to get the earliest and latest timestamps and return the difference between them and now function(keys,values,rereduce) { var now = new Date().valueOf(); var first = Number.MIN_VALUE; var last = Number.MAX_VALUE; if (rereduce) { first = Math.max(first,values[0].first); last = Math.min(last,values[0].last); } else { first = keys[0][0][1]; last = keys[keys.length-1][0][1]; } return {first:now - first, last:now - last}; } and when processing a query it constantly raises the following execption: function raised exception (new TypeError("keys has no properties", "", 1)) I am making sure not to reference keys inside my rereduce block. Why does this function constantly raise this exception?
