• Report Viewer Configuration error - In View Source of webpage

  - by sarada

  I found the following error message when I checked View source of the web page , but the web page works just fine. Our Test lead found the error while performing Assertion tests. Report Viewer Configuration Error The Report Viewer Web Control HTTP Handler has not been registered in the application's web.config file. Add <add verb=" * " path="Reserved.ReportViewerWebControl.axd" type = "Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" /> to the system.web/httpHandlers section of the web.config file, or add <add name="ReportViewerWebControlHandler" preCondition="integratedMode" verb="*" path="Reserved.ReportViewerWebControl.axd" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" /> to the system.webServer/handlers section for Internet Information Services 7 or later Why is this error message coming up in view source.. Note:There is a div tag around this error message which has style="display:none" I am trying to find out why but everybody has only discussed this error message as one which is thrown in the webpage. The changes suggested to web.config are already present in our config file.

• How to hide the title bar while application is loading and show it when it finishes loading?

  - by Arci

  I have an application which uses a custom title bar. However, when my application launches, I noticed that the default title bar is shown for a brief period of time. My problem is I don't want to show the default title bar while my application is loading. How do I hide the title bar while my application is loading so that there will be no hint of it and then show it afterwards? So far, I tried the following solutions but none have worked: Hide the title bar in XML and then set the custom title bar in code. (Problem encountered: I received an error message saying: "You cannot combine custom titles with other title features".) In XML: <item name="android:windowNoTitle">true</item> In onCreate method: requestWindowFeature(Window.FEATURE_CUSTOM_TITLE); //... some code goes here getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.title_header); Set the size of the title bar in XML to 0. Then change it's size via code later. (Problem encountered: I don't know how to set the size of title bar in code. Is it possible? I tried getWindow().setAttributes() and getWindow().setLayout() but both of them didn't worked.)" In XML: <item name="android:windowTitleSize">30dp</item> Modify windowTitleBackgroundStyle and set a transparent drawable as background. (Problem encountered: The content of the title bar became invisible but a line below the title bar is still visible.) In XML: <!-- style used by windowTitleBackgroundStyle --> <item name="android:background">@drawable/transparent</item>

• Why is -webkit-keyframes not working in my SASS mixin?

  - by Tintin81

  I have this SASS mixin that should make a button flash: @mixin background_animation($color) { -webkit-animation: backgroundAnimation 800ms infinite; @-webkit-keyframes backgroundAnimation { 0% {background-color: $color;} 50% {background-color: red;} 100% {background-color: $color;} } } I am using it like this: @include background_animation(#000000); However, it's not working. The background color of the button won't flash. Can anybody tell me what I'm missing here? P.S. The code works fine when not including it as a mixin. The generated CSS looks like this: -webkit-animation-delay: 0s; -webkit-animation-direction: normal; -webkit-animation-duration: 0.800000011920929s; -webkit-animation-fill-mode: none; -webkit-animation-iteration-count: infinite; -webkit-animation-name: backgroundAnimation; -webkit-animation-timing-function: cubic-bezier(0.25, 0.1, 0.25, 1); ... other rules omitted for brevity

• Flash CS5 screwed up all my textfields - how can I correct this?

  - by WillyCornbread

  Hi - I have an Actionscript project that I was building using Flash CS4. I embedded a font using the follow: [Embed(source="/bin/assets/fonts/MyriadPro-Regular.otf", fontWeight="normal", fontFamily="Myriad Pro")] Then throughout my application in my TextFields I would set embedFonts to true antialiastype to advanced and set the thickness property of the text field. And setting the font-family from a stylesheet. This was all working exactly as I expected it would with no issues whatsoever and months of development. I just upgraded to CS5 and published and none of my text is rendered at all. I was able to resolve this by removing the embedFonts = true from the textfields, but this leaves me with no control over the thickness at all. I searched everywhere, does anyone know what the proper way to do this in CS5 is now? I've tried embedding my font directly within the CS5 IDE but still no thickness control. Thanks in advance for any help - I've got tons of textfields throughout my app that are all ganked right now. Thanks Adobe. b

• How should I define a JavaScript 'namespace' to satisfy JSLint?

  - by Matthew Murdoch

  I want to be able to package my JavaScript code into a 'namespace' to prevent name clashes with other libraries. Since the declaration of a namespace should be a simple piece of code I don't want to depend on any external libraries to provide me with this functionality. I've found various pieces of advice on how to do this simply but none seem to be free of errors when run through JSLint (using 'The Good Parts' options). As an example, I tried this from Advanced JavaScript (section Namespaces without YUI): "use strict"; if (typeof(MyNamespace) === 'undefined') { MyNamespace = {}; } Running this through JSLint gives the following errors: Problem at line 2 character 12: 'MyNamespace' is not defined. Problem at line 3 character 5: 'MyNamespace' is not defined. Implied global: MyNamespace 2,3 The 'Implied global' error can be fixed by explicitly declaring MyNamespace... "use strict"; if (typeof(MyNamespace) === 'undefined') { var MyNamespace = {}; } ...and the other two errors can be fixed by declaring the variable outside the if block. "use strict"; var MyNamespace; if (typeof(MyNamespace) === 'undefined') { MyNamespace = {}; } So that works, but it seems to me that (since MyNamespace will always be undefined at the point it is checked?) it is equivalent to the much simpler: "use strict"; var MyNamespace = {}; JSLint is content with this but I'm concerned that I've simplified the code to such an extent that it will no longer function correctly as a namespace. Is this final formulation sensible?

• Devexpress Repository ComboBoxEdit loosing cursor position. Edit.SelectionStart Not being assigned

  - by user575219

  I am having an issue with my comboBoxEdit in a gridcontrol. I am using Winforms Devepress 11.2. I clicked in the text of an existing Repository comboBoxEdit, and typed in "appear backwards", however, it displayed as "sdrawkcab raeppa" like it would in a mirror. There are some posts about this topic but none of the solutions seem to work The reason for this is the following foreach (GridColumn column in this.gvNotes.Columns) { var columnEdit = column.ColumnEdit; if (columnEdit != null) { column.ColumnEdit.EditValueChanged += this.PostEditValueChanged; } } private void PostEditValueChanged(object sender, EventArgs e) { this.gvNotes.PostEditor(); } This PostEditor ensures the save button is enabled when the user is still in the current cell. The user does not need to leave the cell or change column for the changes to be posted to the grid. So this is what I did: private void PostEditValueChanged(object sender, EventArgs e) { ComboBoxEdit edit = this.gridNotes.FocusedView.ActiveEditor as ComboBoxEdit; if (edit != null) { int len = edit.SelectionLength; int start = edit.SelectionStart; gridNotes.FocusedView.PostEditor(); edit.SelectionLength = len; edit.SelectionStart = start; } This did not solve the problem of the cursor resetting to the start position. Edit.SelectionStart is not being assinged to the len value.Even though len changes to 1 edit.SelectionStart remains at 0 Does anyone know what event needs to be handled to not loose the cursor position?

• python os.mkfifo() for Windows

  - by user302099

  Hello. Short version (if you can answer the short version it does the job for me, the rest is mainly for the benefit of other people with a similar task): In python in Windows, I want to create 2 file objects, attached to the same file (it doesn't have to be an actual file on the hard-drive), one for reading and one for writing, such that if the reading end tries to read it will never get EOF (it will just block until something is written). I think in linux os.mkfifo() would do the job, but in Windows it doesn't exist. What can be done? (I must use file-objects). Some extra details: I have a python module (not written by me) that plays a certain game through stdin and stdout (using raw_input() and print). I also have a Windows executable playing the same game, through stdin and stdout as well. I want to make them play one against the other, and log all their communication. Here's the code I can write (the get_fifo() function is not implemented, because that's what I don't know to do it Windows): class Pusher(Thread): def __init__(self, source, dest, p1, name): Thread.__init__(self) self.source = source self.dest = dest self.name = name self.p1 = p1 def run(self): while (self.p1.poll()==None) and\ (not self.source.closed) and (not self.source.closed): line = self.source.readline() logging.info('%s: %s' % (self.name, line[:-1])) self.dest.write(line) self.dest.flush() exe_to_pythonmodule_reader, exe_to_pythonmodule_writer =\ get_fifo() pythonmodule_to_exe_reader, pythonmodule_to_exe_writer =\ get_fifo() p1 = subprocess.Popen(exe, shell=False, stdin=subprocess.PIPE, stdout=subprocess.PIPE) old_stdin = sys.stdin old_stdout = sys.stdout sys.stdin = exe_to_pythonmodule_reader sys.stdout = pythonmodule_to_exe_writer push1 = Pusher(p1.stdout, exe_to_pythonmodule_writer, p1, '1') push2 = Pusher(pythonmodule_to_exe_reader, p1.stdin, p1, '2') push1.start() push2.start() ret = pythonmodule.play() sys.stdin = old_stdin sys.stdout = old_stdout

• How to center list tags inside an unordered list?

  How can list tags that are given a display:block and are floated left, be centered inside an unordered list. The HTML: <div id="navigation"> <ul> <li>Home</li> <li>About Us</li> <li>Contact</li> <li>News</li> <li>Events</li> <li>Video</li> <li>Photos</li> </ul> </div><!-- navigation --> The CSS: #navigation { border: 3px solid orange; overflow: hidden; } #navigation ul { list-style-type: none; text-align: center; } #navigation ul li { float: left; display: block; padding: 10px 8px; border: 1px solid green; }

• Wrapping text and div as a unit

  - by mathee

  I have the following that I would like wrapped as units. <div class='tag-box'> <a href=#>Axe Committee</a> <div class='circle'><a href=#>x</a></div> </div> The CSS for these classes are: .tag-box { display:inline; } .circle { display:inline; padding-left:4px; padding-right:4px; background:rgb(196,15,24); /*dark red*/ -moz-border-radius:10px; -webkit-border-radius:10px; } .circle a { font-size:10px; text-decoration:none; color:#fff; position:relative; top:-2px; } I can have upwards of 20 or 30 of these tag-boxes displayed inline. The problem is that the wrapping will break the words from each other or even break the red circle from the link. This makes it hard to differentiate which circle belongs to which link. (In the future, each circle corresponds to a different action with respect to the link.) See below. How do I prevent this kind of wrapping from occurring?

• Django: Determining if a user has voted or not

  - by TheLizardKing

  I have a long list of links that I spit out using the below code, total votes, submitted by, the usual stuff but I am not 100% on how to determine if the currently logged in user has voted on a link or not. I know how to do this from within my view but do I need to alter my below view code or can I make use of the way templates work to determine it? I have read http://stackoverflow.com/questions/1528583/django-vote-up-down-method but I don't quite understand what's going on ( and don't need any ofjavascriptery). Models (snippet): class Link(models.Model): category = models.ForeignKey(Category, blank=False, default=1) user = models.ForeignKey(User) created = models.DateTimeField(auto_now_add=True) modified = models.DateTimeField(auto_now=True) url = models.URLField(max_length=1024, unique=True, verify_exists=True) name = models.CharField(max_length=512) def __unicode__(self): return u'%s (%s)' % (self.name, self.url) class Vote(models.Model): link = models.ForeignKey(Link) user = models.ForeignKey(User) created = models.DateTimeField(auto_now_add=True) def __unicode__(self): return u'%s vote for %s' % (self.user, self.link) Views (snippet): def hot(request): links = Link.objects.select_related().annotate(votes=Count('vote')).order_by('-created') for link in links: delta_in_hours = (int(datetime.now().strftime("%s")) - int(link.created.strftime("%s"))) / 3600 link.popularity = ((link.votes - 1) / (delta_in_hours + 2)**1.5) if request.user.is_authenticated(): try: link.voted = Vote.objects.get(link=link, user=request.user) except Vote.DoesNotExist: link.voted = None links = sorted(links, key=lambda x: x.popularity, reverse=True) links = paginate(request, links, 15) return direct_to_template( request, template = 'links/link_list.html', extra_context = { 'links': links, }) The above view actually accomplishes what I need but in what I believe to be a horribly inefficient way. This causes the dreaded n+1 queries, as it stands that's 33 queries for a page containing just 29 links while originally I got away with just 4 queries. I would really prefer to do this using Django's ORM or at least .extra(). Any advice?

• DefaultTableCellRenderer getTableCellRendererComponent never gets called

  - by Dean Schulze

  I need to render a java.util.Date in a JTable. I've implemented a custom renderer that extends DefaultTableCellRenderer (below). I've set it as the renderer for the column, but the method getTableCellRendererComponent() never gets called. This is a pretty common problem, but none of the solutions I've seen work. public class DateCellRenderer extends DefaultTableCellRenderer { String sdfStr = "yyyy-MM-dd HH:mm:ss.SSS"; SimpleDateFormat sdf = new SimpleDateFormat(sdfStr); public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) { super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column); if (value instanceof Date) { this.setText(sdf.format((Date) value)); } else logger.info("class: " + value.getClass().getCanonicalName()); return this; } } I've installed the custom renderer (and verified that it has been installed) like this: DateCellRenderer dcr = new DateCellRenderer(); table.getColumnModel().getColumn(2).setCellRenderer(dcr); I've also tried table.setDefaultRenderer( java.util.Date.class, dcr ); Any idea why the renderer gets installed, but never called?

• Blackberry (Java) - Can't get KeyListener to work

  I am trying to get the KeyListener working for Blackberry, but none of the Dialogs pop up indicating that a key has been pressed (see code below, each action has a dialog popup in them). Any ideas on what i might be doing wrong? public class CityInfo extends UiApplication implements KeyListener { static CityInfo application; public static void main(String[] args) { //create a new instance of the application //and start the application on the event thread application.enterEventDispatcher(); } public CityInfo() { //display a new screen application = new CityInfo(); pushScreen(new WorkflowDisplayScreen()); this.addKeyListener(this); } public boolean keyChar(char arg0, int arg1, int arg2) { // TODO Auto-generated method stub Dialog.alert("key pressed : " + arg0); return true; } public boolean keyDown(int keycode, int time) { // TODO Auto-generated method stub Dialog.alert("keyDown : " + keycode); return false; } public boolean keyRepeat(int keycode, int time) { // TODO Auto-generated method stub Dialog.alert("keyRepeat : " + keycode); return false; } public boolean keyStatus(int keycode, int time) { // TODO Auto-generated method stub Dialog.alert("keyStatus : " + keycode); return false; } public boolean keyUp(int keycode, int time) { Dialog.alert("keyUp : " + keycode); // TODO Auto-generated method stub return false; } } I also tried implementing keyChar on the MainScreen class but that did not yield any results either.

• Liftweb Menu customization

  - by DataSurfer

  I want to create a menu that looks like: HOME | FOO | BAR | ABOUT | CONTACT How might I go about doing this? Here is what I have tried: <lift:Menu.builder ul:class="menu" li_item:class="current" /> and ul.menu li { display: inline; list-style-type: none; text-transform: uppercase; border-right: 1px solid white; padding-right: 5px; } li.current span { background: white; color: black; padding: 5px 5px 3px 5px; font-size: 11px; } li.current a, a:visited, a:link { color: white; padding: 5px 5px 3px 5px; font-size: 11px; } This gets close, but it doesn't look quite right. Also you end up with an extra line at the end. I want the lines to be the same height as the text. http://lh5.ggpht.com/_5DxlOp9F12k/S2aFQHfupzI/AAAAAAAAJiY/Ds0IpEyu78I/s800/menu.png

• sqlalchemy dynamic mapping

  - by adancu

  Hi, I have the following problem: I have the class: class Word(object): def __init__(self): self.id = None self.columns = {} def __str__(self): return "(%s, %s)" % (str(self.id), str(self.columns)) self.columns is a dict which will hold (columnName:columnValue) values. The name of the columns are known at runtime and they are loaded in a wordColumns list, for example wordColumns = ['english', 'korean', 'romanian'] wordTable = Table('word', metadata, Column('id', Integer, primary_key = True) ) for columnName in wordColumns: wordTable.append_column(Column(columnName, String(255), nullable = False)) I even created a explicit mapper properties to "force" the table columns to be mapped on word.columns[columnName], instead of word.columnName, I don't get any error on mapping, but it seems that doesn't work. mapperProperties = {} for column in wordColumns: mapperProperties['columns[\'%']' % column] = wordTable.columns[column] mapper(Word, wordTable, mapperProperties) When I load a word object, SQLAlchemy creates an object which has the word.columns['english'], word.columns['korean'] etc. properties instead of loading them into word.columns dict. So for each column, it creates a new property. Moreover word.columns dictionary doesn't even exists. The same way, when I try to persist a word, SQLAlchemy expects to find the column values in properties named like word.columns['english'] (string type) instead of the dictionary word.columns. I have to say that my experience with Python and SQLAlchemy is quite limited, maybe it isn't possible to do what I'm trying to do. Any help appreciated, Thanks in advance.

• (JBoss) Problem with .war project on production, while test works

  - by ikky

  Hello. I have a java project (using Spring mvc) which i have built and deployed on my local computer. It runs on a JBoss application server, and works fine on the local machine. The next step i do, is to copy the deployed project.war from the local machine to the server which has the same development environment as the local machine. I stop the JBoss server, delete the cache, and run the JBoss server again. When i now try to run one of the pages(xx.xxx.xxx:8080/webservice/test.htm), i get this exception: exception org.springframework.web.util.NestedServletException: Request processing failed; nested exception is java.lang.NullPointerException org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:583) root cause java.lang.NullPointerException com.project.db.DBCustomer.isCredentialsCorrect(DBCustomer.java:44) com.project.CreateHController.handleRequest(CreateHController.java:60) org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter.handle(SimpleControllerHandlerAdapter.java:48) org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:875) org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:807) org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:571) org.springframework.web.servlet.FrameworkServlet.doGet(FrameworkServlet.java:501) javax.servlet.http.HttpServlet.service(HttpServlet.java:697) javax.servlet.http.HttpServlet.service(HttpServlet.java:810) org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:75) It seems like none of my classes are reachable.

• Make TBODY scrollable in Webkit browsers

  - by Andrew

  I'm aware of this question, but none of the answers work in Safari, Chrome, etc. The accepted strategy (as demonstrated here) is to set the tbody height and overflow properties like so: <table> <thead> <tr><th>This is the header and doesn't scroll</th></tr> </thead> <tbody style="height:100px; overflow:auto;"> <tr><td>content that scrolls</td></tr> <tr><td>content that scrolls</td></tr> <tr><td>content that scrolls</td></tr> <tr><td>content that scrolls</td></tr> <tr><td>content that scrolls</td></tr> <tr><td>content that scrolls</td></tr> <tr><td>content that scrolls</td></tr> </tbody> </table> Unfortunately, this does not work in any webkit browsers. There is a bug report about it that doesn't seem to be a high priority (reported June 05). So my question is: are there alternate strategies that do actually work? I've tried the two-table approach, but it's impossible to guarantee that the header will line up with the content. Do I just have to wait for Webkit to fix it?

• Visual Studio 2008 Unit test does not pick up code changes unless I build the entire solution

  - by Orion Edwards

  Here's the scenario: Change my code: Change my unit test for that code With the cursor inside the unit test class/method, invoke VS2008's "Run tests in current context" command The visual studio "Output" window indicates that the code dll and the test dll both successfully build (in that order) The problem is however, that the unit test does not use the latest version of the dll which it has just built. Instead, it uses the previously built dll (which doesn't have the updated code in it), so the test fails. When adding a new method, this results in a MethodNotImplementedException, and when adding a class, it results in a TypeLoadException, both because the unit test thinks the new code is there, and it isn't!. If I'm just updating an existing method, then the test just fails due to incorrect results. I can 'work around' the problem by doing this Change my code: Change my unit test for that code Invoke VS2008's 'Build Solution' command With the cursor inside the unit test class/method, invoke VS2008's "Run tests in current context" command The problem is that doing a full build solution (even though nothing has changed) takes upwards of 30 seconds, as I have approx 50 C# projects, and VS2008 is not smart enough to realize that only 2 of them need to be looked at. Having to wait 30 seconds just to change 1 line of code and re-run a unit test is abysmal. Is there anything I can do to fix this? None of my code is in the GAC or anything funny like that, it's just ordinary old dll's (buiding against .NET 3.5SP1 on a win7/64bit machine) Please help!

• Why is my Scala function returning type Unit and not whatever is the last line?

  I am trying to figure out the issue, and tried different styles that I have read on Scala, but none of them work. My code is: .... val str = "(and x y)"; def stringParse ( exp: String, pos: Int, expreshHolder: ArrayBuffer[String], follow: Int ) var b = pos; //position of where in the expression String I am currently in val temp = expreshHolder; //holder of expressions without parens var arrayCounter = follow; //just counts to make sure an empty spot in the array is there to put in the strings if(exp(b) == '(') { b = b + 1; while(exp(b) == ' '){b = b + 1} //point of this is to just skip any spaces between paren and start of expression type if(exp(b) == 'a') { temp(arrayCounter) = exp(b).toString; b = b+1; temp(arrayCounter)+exp(b).toString; b = b+1; temp(arrayCounter) + exp(b).toString; arrayCounter+=1} temp; } } val hold: ArrayBuffer[String] = stringParse(str, 0, new ArrayBuffer[String], 0); for(test <- hold) println(test); My error is: Driver.scala:35: error: type mismatch; found : Unit required: scala.collection.mutable.ArrayBuffer[String] ho = stringParse(str, 0, ho, 0); ^one error found When I add an equals sign after the arguments in the method declaration, like so: def stringParse ( exp: String, pos: Int, expreshHolder: ArrayBuffer[String], follow: Int ) ={....} It changes it to "Any".

• Crosstab with multiple items

  - by Michael Wexler

  In SPSS, it is (relatively) easy to create a cross tab with multiple variables using the factors as the table heading. So, something like the following (made up data, etc.). Q1, Q2, and Q3 each have either a 1, a 2, or a 3 for each person. 1 (very Often) 2 (Rarely) 3 (Never) Q1. Likes it 12 15 13 Q2. Recommends it 22 11 10 Q3. Used it 22 12 9 In SPSS, one can even request row, column, or total percentages. I've tried table(), ftable(), xtab(), CrossTable() from gmodels, and CrossTable() from descr, and none of these can handle (afaik) multiple variables; they mostly seem to handle 1 variable crossed with another variable, and the 3rd creates layers. Is there a package with some good cross tabbing/table examples that I could use to figure this out? I'm sure I'm missing something simple, so I appreciate you pointing out what I missed. Perhaps I have to generate each row as a separate list and then make a dataframe and print the dataframe?

• Specifying different initial values for fields in inherited models (django)

  - by Shawn Chin

  Question : What is the recommended way to specify an initial value for fields if one uses model inheritance and each child model needs to have different default values when rendering a ModelForm? Take for example the following models where CompileCommand and TestCommand both need different initial values when rendered as ModelForm. # ------ models.py class ShellCommand(models.Model): command = models.Charfield(_("command"), max_length=100) arguments = models.Charfield(_("arguments"), max_length=100) class CompileCommand(ShellCommand): # ... default command should be "make" class TestCommand(ShellCommand): # ... default: command = "make", arguments = "test" I am aware that one can used the initial={...} argument when instantiating the form, however I would rather store the initial values within the context of the model (or at least within the associated ModelForm). My current approach What I'm doing at the moment is storing an initial value dict within Meta, and checking for it in my views. # ----- forms.py class CompileCommandForm(forms.ModelForm): class Meta: model = CompileCommand initial_values = {"command":"make"} class TestCommandForm(forms.ModelForm): class Meta: model = TestCommand initial_values = {"command":"make", "arguments":"test"} # ------ in views FORM_LOOKUP = { "compile": CompileCommandFomr, "test": TestCommandForm } CmdForm = FORM_LOOKUP.get(command_type, None) # ... initial = getattr(CmdForm, "initial_values", {}) form = CmdForm(initial=initial) This feels too much like a hack. I am eager for a more generic / better way to achieve this. Suggestions appreciated. Other attempts I have toyed around with overriding the constructor for the submodels: class CompileCommand(ShellCommand): def __init__(self, *args, **kwargs): kwargs.setdefault('command', "make") super(CompileCommand, self).__init__(*args, **kwargs) and this works when I try to create an object from the shell: >>> c = CompileCommand(name="xyz") >>> c.save() <CompileCommand: 123> >>> c.command 'make' However, this does not set the default value when the associated ModelForm is rendered, which unfortunately is what I'm trying to achieve. Update 2 (looks promising) I now have the following in forms.py which allow me to set Meta.default_initial_values without needing extra code in views. class ModelFormWithDefaults(forms.ModelForm): def __init__(self, *args, **kwargs): if hasattr(self.Meta, "default_initial_values"): kwargs.setdefault("initial", self.Meta.default_initial_values) super(ModelFormWithDefaults, self).__init__(*args, **kwargs) class TestCommandForm(ModelFormWithDefaults): class Meta: model = TestCommand default_initial_values = {"command":"make", "arguments":"test"}
