• Using PHP and cURL to login to indyarocks.com

  - by Divya

  I am new to cURL and don't know much about it. I basically want to login to my account on www.indyarocks.com through libcurl for PHP. I don't know what type of authentication it uses (I don't know how to find that out.). When I go to http://www.indyarocks.com, I get a login form which asks for my username and password. I put in my username and password and click login and everything is good. I tried to automate this using cURL. This is a snippet of my code. curl_setopt($curl_connection, CURLOPT_URL, "http://www.indyarocks.com/loginchk.php"); curl_setopt($curl_connection, CURLOPT_POST, 1); curl_setopt($curl_connection, CURLOPT_HTTPAUTH, CURLAUTH_ANY); curl_setopt($curl_connection, CURLOPT_USERPWD, $username.':'.$password); I looked at the source of the login page and found out the address of the page to which the username and password are sent (the action attribute of the form) which is "http://www.indyarocks.com/loginchk.php" and set it as the target url. When I run this, I get username or password is wrong error and the login fails. My username and password is correct. I don't know what the problem is. Can the password be encrypted? Can that be responsible for this failure? Please help me get around this problem. I'll be really thankful. Thanks in advance.

• Binding value for NSTableView, but tooltip gets set as well

  - by Mark

  I've set up an NSTableView in Interface Builder to be populated from an NSArray. Each value of the array represents one row in the table. The value is bound correctly, but as a side effect, the table cell's tooltip is set to the string representation of the bound object. In my case, the NSArray contains NSDictiorany objects and the tooltip looks like it could be the [... description] output of that dictionary. Very ugly... I don't want the tooltip to be set at all. I have other tables that have plain NSString values bound to them and they don't have a tooltip set automatically. Is there some Interface Builder magic going on? I tried to start with a blank project - same problem. I should add that the table cell is a custom implementation of NSTextFieldCell that uses an NSButtonCell instance to draw an image and a label into the table. The values are retrieved from the dictionary bound as value. Why is the tooltip set when I only bind the "value" attribute? Thanks in advance!

• Is it possible to refer to metadata of the target from within the target implementation in MSBuild?

  - by mark

  Dear ladies and sirs. My msbuild targets file contains the following section: <ItemGroup> <Targets Include="T1"> <Project>A\B.sln"</Project> <DependsOnTargets>The targets T1 depends on</DependsOnTargets> </Targets> <Targets Include="T2"> <Project>C\D.csproj"</Project> <DependsOnTargets>The targets T2 depends on</DependsOnTargets> </Targets> ... </ItemGroup> <Target Name="T1" DependsOnTargets="The targets T1 depends on"> <MSBuild Projects="A\B.sln" Properties="Configuration=$(Configuration)" /> </Target> <Target Name="T2" DependsOnTargets="The targets T2 depends on"> <MSBuild Projects="C\D.csproj" Properties="Configuration=$(Configuration)" /> </Target> As you can see, A\B.sln appears twice: As Project metadata of T1 in the ItemGroup section. In the Target statement itself passed to the MSBuild task. I am wondering whether I can remove the second instance and replace it with the reference to the Project metadata of the target, which name is given to the Target task? Exactly the same question is asked for the (Targets.DependsOnTargets) metadata. It is mentioned twice much like the %(Targets.Project) metadata. Thanks. EDIT: I should probably describe the constraints, which must be satisfied by the solution: I want to be able to build individual projects with ease. Today I can simply execute msbuild file.proj /t:T1 to build the T1 target and I wish to keep this ability. I wish to emphasize, that some projects depend on others, so the DependsOnTargets attribute is really necessary for them.

• Ant: use include and exclude together

  - by Ken

  OK, this seems like it should be really simple. I'm using Apache Ant 1.8, and I have a target which does: <delete file="output/program.tar.bz2"/> <tar basedir="input" destfile="output/program.tar.bz2" compression="bzip2"> <tarfileset dir="input"> <include name="goodfolder1/**"/> <include name="goodfolder2/**"/> <exclude name="**/badfile"/> <exclude name="**/*.badext"/> </tarfileset> </tar> I want it to make a .tar.bz2 of input/goodfolder1 and input/goodfolder2, excluding files named "badfile", and excluding files with extension ".badext". It's giving me a .tar.bz2, but it's including badfile and *.badext -- the excludes seem to be ignored. The order of include/exclude doesn't seem to make a difference. I tried wrapping the includes/excludes in a (the docs say it's implicit?), but it made no difference. I'm sure there's something simple I'm missing, since the manual has a very similar example, though in a somewhat different context. EDIT: It looks like it could be related to the dir="input" attribute: it's adding everything in "input", and then adding everything in the tarfileset to that. Files I want appear twice in the program.tar.bz2, but files that are excluded only appear once. But dir is mandatory, and I don't see how this is different from the examples in the manual.

• Doubt about instance creation by using Spring framework ???

  - by Arthur Ronald F D Garcia

  Here goes a command object which needs to be populated from a Spring form public class Person { private String name; private Integer age; /** * on-demand initialized */ private Address address; // getter's and setter's } And Address public class Address { private String street; // getter's and setter's } Now suppose the following MultiActionController @Component public class PersonController extends MultiActionController { @Autowired @Qualifier("personRepository") private Repository<Person, Integer> personRepository; /** * mapped To /person/add */ public ModelAndView add(HttpServletRequest request, HttpServletResponse response, Person person) throws Exception { personRepository.add(person); return new ModelAndView("redirect:/home.htm"); } } Because Address attribute of Person needs to be initialized on-demand, i need to override newCommandObject to create an instance of Person to initiaze address property. Otherwise, i will get NullPointerException @Component public class PersonController extends MultiActionController { /** * code as shown above */ @Override public Object newCommandObject(Class clazz) thorws Exception { if(clazz.isAssignableFrom(Person.class)) { Person person = new Person(); person.setAddress(new Address()); return person; } } } Ok, Expert Spring MVC and Web Flow says Options for alternate object creation include pulling an instance from a BeanFactory or using method injection to transparently return a new instance. First option pulling an instance from a BeanFactory can be written as @Override public Object newCommandObject(Class clazz) thorws Exception { /** * Will retrieve a prototype instance from ApplicationContext whose name matchs its clazz.getSimpleName() */ getApplicationContext().getBean(clazz.getSimpleName()); } But what does he want to say by using method injection to transparently return a new instance ??? Can you show how i implement what he said ??? ATT: I know this funcionality can be filled by a SimpleFormController instead of MultiActionController. But it is shown just as an example, nothing else

I see the error only in django 1.1. Do you have an idea what am I doing wrong? Regards, Arshavski Alexander.

• Can I run a JavaScript function AFTER Google Loader has run?

  - by thatryan

  I am loading Google API using google.load() and I need to process some of what is built by it, but I need to run the JavaScript after it has already completely loaded, is there a way to ensure that happens? Here is how I build the list of images, I need to add an attribute to each img tag though, can't do that until after it is built right? google.load("feeds", "1"); function initialize() { var feed = new google.feeds.Feed("myfeed.rss"); feed.load(function(result) { if (!result.error) { var container = document.getElementById("feed"); for (var i = 0; i < result.feed.entries.length; i++) { var entry = result.feed.entries[i]; var entryTitle = entry.title; var entryContent = entry.content; imgContent = entryContent + "<p>"+entryTitle+"</p>"; var div = document.createElement("div"); div.className = "image"; div.innerHTML = imgContent; container.appendChild(div); } } }); } google.setOnLoadCallback(initialize);

• How to perform Rails model validation checks within model but outside of filters using ledermann-rails-settings and extensions

  - by user1277160

  Background I'm using ledermann-rails-settings (https://github.com/ledermann/rails-settings) on a Rails 2/3 project to extend virtually the model with certain attributes that don't necessarily need to be placed into the DB in a wide table and it's working out swimmingly for our needs. An additional reason I chose this Gem is because of the post How to create a form for the rails-settings plugin which ties ledermann-rails-settings more closely to the model for the purpose of clean form_for usage for administrator GUI support. It's a perfect solution for addressing form_for support although... Something that I'm running into now though is properly validating the dynamic getters/setters before being passed to the ledermann-rails-settings module. At the moment they are saved immediately, regardless if the model validation has actually fired - I can see through script/console that validation errors are being raised. Example For instance I would like to validate that the attribute :foo is within the range of 0..100 for decimal usage (or even a regex). I've found that with the previous post that I can use standard Rails validators (surprise, surprise) but I want to halt on actually saving any values until those are addressed - ensure that the user of the GUI has given 61.43 as a numerical value. The following code has been borrowed from the quoted post. class User < ActiveRecord::Base has_settings validates_inclusion_of :foo, :in => 0..100 def self.settings_attr_accessor(*args) >>SOME SORT OF UNLESS MODEL.VALID? CHECK HERE args.each do |method_name| eval " def #{method_name} self.settings.send(:#{method_name}) end def #{method_name}=(value) self.settings.send(:#{method_name}=, value) end " end >>END UNLESS end settings_attr_accessor :foo end Anyone have any thoughts here on pulling the state of the model at this point outside of having to put this into a before filter? The goal here is to be able to use the standard validations and avoid rolling custom validation checks for each new settings_attr_accessor that is added. Thanks!

• Rails 3 Timezone error

  - by Juan

  I am struggling with time zone support in Rails 3 beta and I would like to know if it is a bug or if I am doing something wrong. He is the problem: > Time.zone = 'Madrid' # it is GMT+2 = "Madrid" > c = Comment.new = #<Comment id: nil, title: "", pub_at: nil> > c.pub_at = Time.zone.parse('10:00:00') = Mon, 31 May 2010 10:00:00 CEST +02:00 > c.save > c = #<Comment id: 3, title: "", pub_at: "2010-05-31 08:00:00"> > c.reload = #<Comment id: 3, title: "", pub_at: "2010-05-31 08:00:00"> ruby-1.8.7-p249 c.pub_at = Mon, 31 May 2010 13:00:00 CEST +02:00 As you can see, the pub_at attribute is stored correctly in the database but when it is retrieved it adds 3 hours and I suspect that it is because it is using my local machine timezone that is in GMT-3. The same sequence of commands in rails 2.3.5 works perfectly. Any toughts? Should I report a ticket?

• XSLT: use parameters in xls:sort attributes (dynamic sorting)

  - by fireeyedboy

  How do I apply a parameter to a select and order attribute in a xsl:sort element? I'ld like to do this dynamic with PHP with something like this: $xsl = new XSLTProcessor(); $xslDoc = new DOMDocument(); $xslDoc->load( $this->_xslFilePath ); $xsl->importStyleSheet( $xslDoc ); $xsl->setParameter( '', 'sortBy', 'viewCount' ); $xsl->setParameter( '', 'order', 'descending' ); But I'ld first have to now how to get this to work.

• Testing InlineFormset clean methods

  - by Rory

  I have a Django project, with 2 models, a Structure and Bracket, the Bracket has a ForeignKey to a Structure (i.e. one-to-many, one Structure has many Brackets). I created a TabularInline for the admin site, so that there would be a table of Brackets on the Structure. I added a custom formset with some a custom clean method to do some extra validation, you can't have a Bracket that conflicts with another Bracket on the same Structure etc. The admin looks like this: class BracketInline(admin.TabularInline): model = Bracket formset = BracketInlineFormset class StructureAdmin(admin.ModelAdmin): inlines = [ BracketInline ] admin.site.register(Structure, StructureAdmin) That all works, and the validation works. However now I want to write some unittest to test my complex formset validation logic. My first attempt to validate known-good values is: data = {'form-TOTAL_FORMS': '1', 'form-INITIAL_FORMS': '0', 'form-MAX_NUM_FORMS': '', 'form-0-field1':'good-value', … } formset = BracketInlineFormset(data) self.assertTrue(formset.is_valid()) However that doesn't work and raises the exception: ====================================================================== ERROR: testValid (appname.tests.StructureTestCase) ---------------------------------------------------------------------- Traceback (most recent call last): File "/paht/to/project/tests.py", line 494, in testValid formset = BracketInlineFormset(data) File "/path/to/django/forms/models.py", line 672, in __init__ self.instance = self.fk.rel.to() AttributeError: 'BracketInlineFormset' object has no attribute 'fk' ---------------------------------------------------------------------- The Django documentation (for formset validation) implies one can do this. How come this isn't working? How do I test the custom clean()/validation for my inline formset?

• Windows 8 Data Binding Bug - OnPropertyChanged Updates Wrong Object

  - by Andrew

  I'm experiencing some really weird behavior with data binding in Windows 8. I have a combobox set up like this: <ComboBox VerticalAlignment="Center" Margin="0,18,0,0" HorizontalAlignment="Right" Height="Auto" Width="138" Background="{StaticResource DarkBackgroundBrush}" BorderThickness="0" ItemsSource="{Binding CurrentForum.SortValues}" SelectedItem="{Binding CurrentForum.CurrentSort, Mode=TwoWay}"> <ComboBox.ItemTemplate> <DataTemplate> <TextBlock HorizontalAlignment="Right" Text="{Binding Converter={StaticResource SortValueConverter}}"/> </DataTemplate> </ComboBox.ItemTemplate> </ComboBox> Inside of a page with the DataContext set to a statically located ViewModel. When I change that ViewModel's CurrentForm attribute, who's property is implemented like this... public FormViewModel CurrentForm { get { return _currentForm; } set { _currentForm = value; if (!_currentForm.IsLoaded) { _currentSubreddit.Refresh.Execute(null); } RaisePropertyChanged("CurrentForm"); } } ... something really strange happens. The previous FormViewModel's CurrentSort property is changed to the new FormViewModel's current sort property. This happens as the RaisePropertyChanged event is called, through a managed-to-native transition, with native code invoking the setter of CurrentSort of the previous FormViewModel. Does that sound like a bug in Win8's data binding? Am I doing something wrong?

• Problem adding a behaviors element to my WCF client config

  I'm trying to add a behaviors element to my client config file so I can specify maxItemsInObjectGraph. The error I get is: The element 'system.serviceModel' has invalid child element 'behaviors'. List of possible elements expected: 'bindings, client, extensions'. Here is my config: <configuration> <system.serviceModel> <bindings> <basicHttpBinding> <binding name="BasicHttpBinding_KernService" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647"> <security mode="None" /> </binding> </basicHttpBinding> </bindings> <behaviors> <endpointBehaviors> <behavior name="ServiceViewEventBehavior"> <dataContractSerializer maxItemsInObjectGraph="2147483647"/> </behavior> </endpointBehaviors> </behaviors> <client> <endpoint address="http://localhost/KernMobile.WCF/KernService.svc" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_KernService" contract="KernWcfService.KernService" name="BasicHttpBinding_KernService" behaviorConfiguration="ServiceViewEventBehavior" /> </client> </system.serviceModel> </configuration> It's also complaining about the behaviorConfiguration attribute in the endpoint element. Any ideas? .Net 4.0 BTW.

• [IceFaces] Why are validators of unchanged components called?

  - by bitschnau

  I have a IceFaces-form and several input fields. Let's say I have this: <ice:selectOneMenu id="accountMenu" value="#{accountController.account.aId}" validator="#{accountController.validateAccount}"> <f:selectItems id="accountItems" value="#{accountController.accountItems}" /> </ice:selectOneMenu> and this: <ice:selectOneMenu id="costumerMenu" value="#{customerController.customer.cId}" validator="#{customerController.validateCustomer"> <f:selectItems id="customerItems" value="#{customerController.customerItems}" /> </ice:selectOneMenu> If I change one value, the respective validator is called, what is fine. But also the other validator is called, which is not fine, because the user get's an irritating message to insert a value to a field he maybe was just going to pay attention to. It's like poking the user with a stick to "Hurry up now!". BAD! I thought the attribute "partialSubmit" is controlling this behaviour, so only the one DOM-part is submitted, which is affected by the user interaction, but if I declare the both components to be partially submitted, nothing changes. Still both validators are called if one component value is changed. How can I prevent the whole form from being validated until it is submitted completely?

• Circular Reference exception with JSON Serialisation with MVC3 and EF4 CTP5w

  - by nakchak

  Hi I'm having problems with a circular reference when i try and serialise an object returned via EF4 CTP5. Im using the code first approach and simple poco's for my model. I have added [ScriptIgnore] attributes to any properties that provide a back references to an object and annoyingly every seems to work fine if i manually instantiate the poco's, i.e. they serialise to JSON fine, and the scriptignore attribute is acknowledged. However when i try and serialise an object returned from the DAL i get the circular reference exception "A circular reference was detected while serializing an object of type 'System.Data.Entity.DynamicProxies.xxxx'" I have tried several ways of retreiving the data but they all get stuck with this error: public JsonResult GetTimeSlot(int id) { TimeSlotDao tsDao = new TimeSlotDao(); TimeSlot ts = tsDao.GetById(id); return Json(ts); } The method below works slightly better as rather than the timeslot dynamic proxied object causing the circular refference its the appointment object. public JsonResult GetTimeSlot(int id) { TimeSlotDao tsDao = new TimeSlotDao(); var ts = from t in tsDao.GetQueryable() where t.Id == id select new {t.Id, t.StartTime, t.Available, t.Appointment}; return Json(ts); } Any ideas or solutions to this problem? Update I would prefer to use the out of the box serialiser if possible although Json.Net via nuget is ok as an alternative i would hope its possible to use it as I intended as well...

• Alternative to using c:out to prevent XSS

  - by lynxforest

  I'm working on preventing cross site scripting (XSS) in a Java, Spring based, Web application. I have already implemented a servlet filter similar to this example http://greatwebguy.com/programming/java/simple-cross-site-scripting-xss-servlet-filter/ which sanitizes all the input into the application. As an extra security measure I would like to also sanitize all output of the application in all JSPs. I have done some research to see how this could be done and found two complementary options. One of them is the use of Spring's defaultHtmlEscape attribute. This was very easy to implement (a few lines in web.xml), and it works great when your output is going through one of spring's tags (ie: message, or form tags). The other option I have found is to not directly use EL expressions such as ${...} and instead use <c:out value="${...}" /> That second approach works perfectly, however due to the size of the application I am working on (200+ JSP files). It is a very cumbersome task to have to replace all inappropriate uses of EL expressions with the c:out tag. Also it would become a cumbersome task in the future to make sure all developers stick to this convention of using the c:out tag (not to mention, how much more unreadable the code would be). Is there alternative way to escape the output of EL expressions that would require fewer code modifications? Thank you in advance.

• Python: Errors saving and loading objects with pickle module

  - by Peterstone

  Hi, I am trying to load and save objects with this piece of code I get it from a question I asked a week ago: Python: saving and loading objects and using pickle. The piece of code is this: class Fruits: pass banana = Fruits() banana.color = 'yellow' banana.value = 30 import pickle filehandler = open("Fruits.obj","wb") pickle.dump(banana,filehandler) filehandler.close() file = open("Fruits.obj",'rb') object_file = pickle.load(file) file.close() print(object_file.color, object_file.value, sep=', ') At a first glance the piece of code works well, getting load and see the 'color' and 'value' of the saved object. But, what I pursuit is to close a session, open a new one and load what I save in a past session. I close the session after putting the line filehandler.close() and I open a new one and I put the rest of your code, then after putting object_file = pickle.load(file) I get this error: Traceback (most recent call last): File "<pyshell#5>", line 1, in <module> object_file = pickle.load(file) File "C:\Python31\lib\pickle.py", line 1365, in load encoding=encoding, errors=errors).load() AttributeError: 'module' object has no attribute 'Fruits' Can anyone explain me what this error message means and telling me how to solve this problem? Thank so much and happy new year!!

• How can I execute an ANTLR parser action for each item in a rule that can match more than one item?

  - by Chris Farmer

  I am trying to write an ANTLR parser rule that matches a list of things, and I want to write a parser action that can deal with each item in the list independently. Some example input for these rules is: $(A1 A2 A3) I'd like this to result in an evaluator that contains a list of three MyIdentEvaluator objects -- one for each of A1, A2, and A3. Here's a snippet of my grammar: my_list returns [IEvaluator e] : { $e = new MyListEvaluator(); } '$' LPAREN op=my_ident+ { /* want to do something here for each 'my_ident'. */ /* the following seems to see only the 'A3' my_ident */ $e.Add($op.e); } RPAREN ; my_ident returns [IEvaluator e] : IDENT { $e = new MyIdentEvaluator($IDENT.text); } ; I think my_ident is defined correctly, because I can see the three MyIdentEvaluators getting created as expected for my input string, but only the last my_ident ever gets added to the list (A3 in my example input). How can I best treat each of these elements independently, either through a grammar change or a parser action change? It also occurred to me that my vocabulary for these concepts is not what it should be, so if it looks like I'm misusing a term, I probably am. EDIT in response to Wayne's comment: I tried to use op+=my_ident+. In that case, the $op in my action becomes an IList (in C#) that contains Antlr.Runtime.Tree.CommonTree instances. It does give me one entry per matched token in $op, so I see my three matches, but I don't have the MyIdentEvaluator instances that I really want. I was hoping I could then find a rule attribute in the ANTLR docs that might help with this, but nothing seemed to help me get rid of this IList. Result... Based on chollida's answer, I ended up with this which works well: my_list returns [IEvaluator e] : { $e = new MyListEvaluator(); } '$' LPAREN (op=my_ident { $e.Add($op.e); } )+ RPAREN ; The Add method gets called for each match of my_ident.

• Which templating languages output HTML *as a tree of nodes*?

  - by alamar

  HTML is a tree of nodes, before all. It's not just a text. However, most templating engines handle their input and output as it was just a text; they don't care what happens around their tags, their {$foo}'s and <% bar() %>'s; also they don't care about what are they outputting. Sometimes they happen to produce a correct html, but that's just a coincidence; they didn't aim for that, all they wanted is to replace some funny marks in the text stream with their evaluation. There are a few templating engines which do treat their output as a set of nodes; XSLT and Haml come to mind. For some tasks, this has advantages: for example, you can automatically reformat (like, delete all empty text nodes; auto-indent; word-wrap). The result is guaranteed to be a correct xml/sgml unless you use a strict subset of operations that can break that. Also, such templating engine would automatically quote strings, differently in text nodes and in attributes, because it strictly knows whether you're writing an attribute or a text node. Moreover, it can conditionally remove a node from output because it knows where it does begin and end, which is useful, and do other non-trivial node operations. You might not like XSLT for its verbosiness or functionalness, but it's damn helps that your template is xmllint-able XML, and your output is a good sgml/xml. So the question is: Which template engines do you know that treat their output as a set of correct nodes, not just an unstructured text? I know XSLT, Haml and some obscure python-based one. Moar!

• Batch File to Delete Folders

  - by Homebrew

  I found some code to delete folders, in this case deleting all but 'n' # of folders. I created 10 test folders, plus 1 that was already there. I want to delete all but 4. The code works, it leaves 4 of my test folders, except that it also leaves the other folder. Is there some attribute of the other folder that's getting checked in the batch file that's stopping it from getting deleted ? It was created through a job a couple of weeks ago. Here's the code I stole (but don't really understand the details): rem DOS - Delete Folders if # folders > n @Echo Off :: User Variables :: Set this to the number of folders you want to keep Set _NumtoKeep=4 :: Set this to the folder that contains the folders to check and delete Set _Path=C:\MyFolder_Temp\FolderTest If Exist "%temp%\tf}1{" Del "%temp%\tf}1{" PushD %_Path% Set _s=%_NumtoKeep% If %_NumtoKeep%==1 set _s=single For /F "tokens=* skip=%_NumtoKeep%" %%I In ('dir "%_Path%" /AD /B /O-D /TW') Do ( If Exist "%temp%\tf}1{" ( Echo %%I:%%~fI >>"%temp%\tf}1{" ) Else ( Echo.>"%temp%\tf}1{" Echo Do you wish to delete the following folders?>>"%temp%\tf}1{" Echo Date Name>>"%temp%\tf}1{" Echo %%I:%%~fI >>"%temp%\tf}1{" )) PopD If Not Exist "%temp%\tf}1{" Echo No Folders Found to delete & Goto _Done Type "%temp%\tf}1{" | More Set _rdflag= /q Goto _Removeold Set _rdflag= :_Removeold For /F "tokens=1* skip=3 Delims=:" %%I In ('type "%temp%\tf}1{"') Do ( If "%_rdflag%"=="" Echo Deleting rd /s%_rdflag% "%%J") :_Done If Exist "%temp%\tf}1{" Del "%temp%\tf}1{"

• get_by_id method on Model classes in Google App Engine Datastore

  I'm unable to workout how you can get objects from the Google App Engine Datastore using get_by_id. Here is the model from google.appengine.ext import db class Address(db.Model): description = db.StringProperty(multiline=True) latitude = db.FloatProperty() longitdue = db.FloatProperty() date = db.DateTimeProperty(auto_now_add=True) I can create them, put them, and retrieve them with gql. address = Address() address.description = self.request.get('name') address.latitude = float(self.request.get('latitude')) address.longitude = float(self.request.get('longitude')) address.put() A saved address has values for >> address.key() aglndWVzdGJvb2tyDQsSB0FkZHJlc3MYDQw >> address.key().id() 14 I can find them using the key from google.appengine.ext import db address = db.get('aglndWVzdGJvb2tyDQsSB0FkZHJlc3MYDQw') But can't find them by id >> from google.appengine.ext import db >> address = db.Model.get_by_id(14) The address is None, when I try >> Address.get_by_id(14) AttributeError: type object 'Address' has no attribute 'get_by_id' How can I find by id? EDIT: It turns out I'm an idiot and was trying find an Address Model in a function called Address. Thanks for your answers, I've marked Brandon as the correct answer as he got in first and demonstrated it should all work.

• check properties of two objects for changes

  - by k-hoffmann

  Hi, i have to develop a mechanism to check two object properties for changes. All properties which are needed to check are marked with an attribute. Atm i - read all properties from acutal object via linq - read the corresponding property from old object - fill an own object with the two properties (old and new value) In Code the call to the workerclass looks like this public void CreateHistoryMap(BaseEntity actual, BaseEntity old) { CreateHistoryMap(actualEntity, oldEntity) .ForEach(mapEntry => CreateHistoryEntry(mapEntry), mapEntry => IfChangesDetected(mapEntry)); } CreateHistoryMap builds up the HistoryMapEntry which contains the two properties. CreateHistoryEntry build up the object which is saved to database, the IfChangesDetected check the object for changes. I have to handle own special application types to generate history values to database (like concatinating list values and so on). My problem is now, that i have to read the values of the properties twice - for change detection - and for the concreate CreateHistoryEntry How can i eliminate this problem or how can i implement the change tracking scenario with the nice c# 3.5 features? Thanks a lot.

• Hibernate saveorUpdate method problem

  - by umesh awasthi

  Hi all, i am trying to work on with Hibernate (Database side for first time) and some how struck in choosing best possible way to use saveOrUpdate or Save.Update i have a destination POJO class and its other attributes which needs to be updated along with the Destination entity. i am getting an XML file to be imported and i am using the following code to update/save the destination entity along with its attribute classes. try{ getSessionFactory().getCurrentSession().beginTransaction(); getSessionFactory().getCurrentSession().saveOrUpdate(entity); getSessionFactory().getCurrentSession().getTransaction().commit(); } catch(Exception e){ getSessionFactory().getCurrentSession().getTransaction().rollback(); } finally{ getSessionFactory().close(); } everything is working fine untill i am using the same session instance.but later on when i am using the same XML file to update the destination PO for certain attributes it giving me the following error. SEVERE: Duplicate entry 'MNLI' for key 'DESTINATIONID' 9 Jan, 2011 4:58:11 PM org.hibernate.event.def.AbstractFlushingEventListener performExecutions SEVERE: Could not synchronize database state with session org.hibernate.exception.ConstraintViolationException: Could not execute JDBC batch update at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:94) at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:66) at org.hibernate.jdbc.AbstractBatcher.executeBatch(AbstractBatcher.java:275) at org.hibernate.jdbc.AbstractBatcher.prepareStatement(AbstractBatcher.java:114) at org.hibernate.jdbc.AbstractBatcher.prepareStatement(AbstractBatcher.java:109) at org.hibernate.jdbc.AbstractBatcher.prepareBatchStatement(AbstractBatcher.java:244) at org.hibernate.persister.entity.AbstractEntityPersister.insert(AbstractEntityPersister.java:2242) at org.hibernate.persister.entity.AbstractEntityPersister.insert(AbstractEntityPersister.java:2678) at org.hibernate.action.EntityInsertAction.execute(EntityInsertAction.java:79) i am using UUID as primary key for the Destination table and in destination table i have a destination id which is unique.but i can understand that in the secodn case hibernate is not able to find if there is already an entry for the same destination in the DB and trying to execute insert statement rather than update. one possible solution is i can user destinationid to check if there is already a destination inplace with the given id and based on the results i can issue save or update command. my question is can this be achieve by any other good way..? Thanks in advance

• Asp MVC - "The Id field is required" validation message on Create; Id not set to [Required]

  - by Dann

  This is happening when I try to create the entity using a Create style action in Asp.Net MVC 2. The POCO has the following properties: public int Id {get;set;} [Required] public string Message {get; set} On the creation of the entity, the Id is set automatically, so there is no need for it on the Create action. The ModelState says that "The Id field is required", but I haven't set that to be so. Is there something automatic going on here? EDIT - Reason Revealed The reason for the issue is answered by Brad Wilson via Paul Speranza in one of the comments below where he says (cheers Paul): You're providing a value for ID, you just didn't know you were. It's in the route data of the default route ("{controller}/{action}/{id}"), and its default value is the empty string, which isn't valid for an int. Use the [Bind] attribute on your action parameter to exclude ID. My default route was: new { controller = "Customer", action = "Edit", id = " " } // Parameter defaults EDIT - Update Model technique I actually changed the way I did this again by using TryUpdateModel and the exclude parameter array asscoiated with that. [HttpPost] public ActionResult Add(Venue collection) { Venue venue = new Venue(); if (TryUpdateModel(venue, null, null, new[] { "Id" })) { _service.Add(venue); return RedirectToAction("Index", "Manage"); } return View(collection); }

• JQuery Tabbed Nav Menu and PHP Forms Question?

  - by SlAcKeR

  I'm using a JQuery Tabbed Menu which holds different types of forms and when I select a different form located under a different tab and submit the form the tab will jump to the default tab instead of the current tab the form is located in. I was wondering how would I go about fixing this so that when the form is submitted the current tab is still selected, is it the JQuery or PHP problem? Here is the JQuery. $(document).ready(function() { //When page loads... $(".form-content").hide(); //Hide all content var firstMenu = $("#home-menu ul li:first"); firstMenu.show(); firstMenu.find("a").addClass("selected-link"); //Activate first tab $(".form-content:first").show(); //Show first tab content //On Click Event $("#home-menu ul li").click(function() { $("#home-menu ul li a").removeClass("selected-link"); //Remove any "selected-link" class $(this).find("a").addClass("selected-link"); //Add "selected-link" class to selected tab $(".form-content").hide(); //Hide all tab content var activeTab = $(this).find("a").attr("href"); //Find the href attribute value to identify the selected-link tab + content $(activeTab).fadeIn(); //Fade in the selected-link ID content return false; }); });
