  • issue in list of dict

    - by gaggina
    class MyOwnClass: # list who contains the queries queries = [] # a template dict template_query = {} template_query['name'] = 'mat' template_query['age'] = '12' obj = MyOwnClass() query = obj.template_query query['name'] = 'sam' query['age'] = '23' obj.queries.append(query) query2 = obj.template_query query2['name'] = 'dj' query2['age'] = '19' obj.queries.append(query2) print obj.queries It gives me [{'age': '19', 'name': 'dj'}, {'age': '19', 'name': 'dj'}] while I expect to have [{'age': '23' , 'name': 'sam'}, {'age': '19', 'name': 'dj'}] I thought to use a template for this list because I'm gonna to use it very often and there are some default variable who does not need to be changed. Why does doing it the template_query itself changes? I'm new to python and I'm getting pretty confused.

  • Customizing RadioSelect

    - by Kugel
    Hello I have a form with ChoiceField whose widget is set to RadioSelect Now to override default html output one needs to subclass RadioFieldRenderer like this: class SimpleRadioFieldRenderer(forms.widgets.RadioFieldRenderer): def render(self): """Outputs widget without <ul> or <li> tags.""" return mark_safe(u'\n'.join([u'%s' % force_unicode(w.tag()) for w in self])) All is good now except I'd like to be able to render 1 radio button at a time from template. Something like this: {{ form.myfield.0 }}} Or perhaps hanging it onto widget itself: {{ form.myfield.field.widget.0 }} What bugs me is that RadioFieldRenderer already implements __get_item__ to get just one RadioInput. The problem is that the renderer does not contain data, neither does the widget. And I'd really hate to mess with Field and BoundField. I need this to inject html before/after each radiobutton and I'd like it to be done in the template. From the code it would be easy. Any ideas are welcome.

  • Using attribute text value in AngularJS directive

    - by C1pher
    Using a YouTube tutorial created by John Lindquist, I was able to create a directive using a template. See fiddle: http://jsfiddle.net/37PSs/ Now, I want to use the value of the attribute as a variable to a function call. Something like this: html: <hello-world name="World"></hello-world> javascript - directive: template: '<span>myFunction({{name}})</span>' javascript - myFunction(theirName): return ("Hello, " + String(theirName) + "!"); The closest I've been able to get is passing an [object Window] to my function.

  • Are Inherited Forms And/Or Inherited Controls possible in Managed C++

    - by Ali Akdurak
    Hello everyone The question is actually pretty self explanatory but I will further clarify it. I am building a simple application to show a load [file] for 5 different types of [files]. So all these 5 forms will have similar GUI elements such as a listbox and a load button with a small textbox/label to show the summary of the [file]'s information. My desired effect is something like visual studio's C# template for Inherited User controls or Inherited forms. I already heavily googled the concept to look for a C++ visual studio template to the trick but I couldn't find it. The word [file] is in brackets because open file dialogue will not the trick as this list of files to select form comes form an SQL server. Thanks a lot!

  • JasperReports-Ireport: How to make the groupfield don't gets repeated every 3rows of fields?

    - by Aaron
    I have a web app and I need to integrate some JasperReports in this app. So I downloaded iReport and I used the templates. I choose the LeafGreen template, but I have a problem.

  • How to create templates in JSTL JSP

    - by desau
    Say I have a JSP page with JSTL. I'm using c:forEach and looping over 5 different sets of objects, each very similar. Each loop is nearly identical.. lots of duplicated code. I'd like to make that loop a template -- such as a JSP template, but I want to pass the JSTL object(s) in the parameters. How can I do this? Or a more general question -- how can I create reusable HTML templates in JSP/JSTL?

  • jQuery change selected option's background on change of selected item

    - by Scott B
    I have a routine that dynamically changes a select list's "selected" option when the corresponding image from a carousel widget is clicked (it's a wordpress template selector). I'd just like to add a flash of background color, then fade to white, to give the user a visual cue that they've just changed the value of the template chooser select list. I've attempted at it below to assign the className "mySelectedOption" to the selected option, but its not working. I'm sure there is perhaps a better way to get the visual cue I'm looking for, (since the css change is static and wont fade back to white background) $('#carousel ul li').click(function(e) { var myOption = $(this).children('img').attr('title'); $("#myTheme option[value='"+myOption+"']").attr('selected', 'selected'); $("#myTheme :selected]").attr('className', 'mySelectedOption'); });

  • How to create a simple server/client application using boost.asio?

    - by the_drow
    I was going over the examples of boost.asio and I am wondering why there isn't an example of a simple server/client example that prints a string on the server and then returns a response to the client. I tried to modify the echo server but I can't really figure out what I'm doing at all. Can anyone find me a template of a client and a template of a server? I would like to eventually create a server/client application that receives binary data and just returns an acknowledgment back to the client that the data is received.

  • App Engine webapp.RequestHandler child instances has no self.request during __init__

  • Add a prefix do Django comment form

    - by Stefan Manastirliu
    I would like to add a prefix to each django comment form. I'm using multiply comment forms in the same page and depsite it's working well, i don't like having many input fields with the same id attribute like <input type="text" name="honeypot" id="id_honeypot" />. So, is there a way to tell django do add a prefix to each form instance? I know i can do it with other forms when i create a form instance in this waynewform = CustomForm(prefix="a") but using Django's comment system, this part is handled by a comment template tag {% get_comment_form for [object] as [varname] %}. Can I tell to the template tag to add a prefix?

  • Register/Include javascript within RenderingTemplate.

    - by Janis Veinbergs
    Is it possible to register (include) javascript within RenderingTemplate? (RenderingTemplates are used to render list forms or fields) By using <SharePoint:RenderingTemplate ID="NewRelatedListItem" runat="server"> <Template> <span id="part1"> <SharePoint:ScriptLink Name="SPFormFieldAssistant.js" Localizable="false" /> ... </span> ... </Template> </SharePoint:RenderingTemplate> it couldn't be done - it didn't include script at HEAD area, but...: Is something wrong with my code? Althought script IS at Layouts folder and I checked with Reflector that it uses Layouts folder if Localizable='False'. I don't want this script to be loaded with every page, but only for forms. Any ideas on how this could be achieved?

  • Access Elements inside a DataTemplate... How to for more than 1 DataTemplate?

    - by GaaTY
    I've got 2 DataTemplates defined for a Listbox Control. 1 Template is for the UnSelected State and the other one is for the Selected State(showing more detail than the UnSelected State). I followed the example here: http://blogs.msdn.com/b/wpfsdk/archive/2007/04/16/how-do-i-programmatically-interact-with-template-generated-elements-part-ii.aspx about how to access the Elements inside the DataTemplates from Code behind. I get it right, but it only finds and returns an element of the UnSelected DataTemplate. But when i search for an element in the Selected DataTemplate i get a NullReferenceException. What could i be doing wrong?

  • Are C++ meta-templates required knowledge for programmers?

    - by Robert Gould
    In my experience Meta-templates are really fun (when your compilers are compliant), and can give good performance boosts, and luckily I'm surrounded by seasoned C++ programmers that also grok meta-templates, however occasionally a new developer arrives and can't make heads or tails of some of the meta-template tricks we use (mostly Andrei Alenxandrescu stuff), for a few weeks until he gets initiated appropriately. So I was wondering what's the situation for other C++ programmers out there? Should meta-template programming be something C++ programmers should be "required" to know (excluding entry level students of course), or not? Edit: Note my question is related to production code and not little samples or prototypes

  • Putting a block inside another in Django

    - by hekevintran
    I have a Django template that I want to extend in multiple places. In some the div must be inside a form, and in others it must not be. To do this I put a block above and below the div so I could add and in them respectively. Desired: <form> <div class="my_div"> {% block div_content %} ... {% endblock %} </div> </form> Template: {% block div_top %}{% endblock %} <div class="my_div"> {% block div_content %} {% endblock %} </div> {% block div_bottom %}{% endblock %} Looking at this I can't help but think that there is a better way to do it. What is the standard Django way of doing this?

  • copy or clone a HSSFWorkbook

    - by Fortega
    Hi, Currently I am doing the following in a loop (at least 300 times): - create a HSSFWorkbook from a template file - add some values to specific cells in the workbook - save the workbook as a new excel file The first line takes about 70% of the time (reading excel file). What I would like to do is to take this out of the loop, and read the file only once. In the loop, I would like to copy or clone the template HSSFWorkbook. However, I can't find anything about copying/cloning a HSSFWorkbook. Did some of you do this before? Any tips?

  • Separation of logic from presentation: HTTP variable names?

    - by Allan Jardine
    Hello all, This could probably be considered an academic question, rather than a real world one - but throwing it out to see if anyone has any great ideas! We all know that keeping the business logic of an application separate from the presentation is a good idea (I'm looking at web-apps atm), but there needs to be an understanding between the business logic for what HTTP variables to expect (and then process) and the variable names which are sent by the presentation layer. Is this simply a matter of telling the designer what variable names to use in a template? The template doesn't need to know what the variable names are (unless using them for JS/CSS selectors), so why should they be 'hardcoded' in there. Or should the business logic put the names into variables to be printed out? Another layer of complexity for the templates? Does anyone have any experience of this, or thoughts on how to deal with it? Thanks, Allan

  • Creating method templates in Eclipse

    - by stevebot
    Is there any way to do the following in eclipse? Have eclipse template a method like the following public void test(){ // CREATE MOCKS // CREATE EXPECTATIONS // REPLAY MOCKS // VERIFY MOCKS } so then I could presumably just use intellisense and select an option like "createtest" and have it stub out a method with the comments similar to the above?My problem is that often myself and other developers I know forgot all the steps we need to follow to do what we dub as a valid unit test for our application. If I could template our test methods to stub out the comments above it would be a big help.

  • WPF: change DataTemples according to Value

    - by Kave
    I have a class called Cell with two properties. One is called Value of type int? And the other is called Candidates of type ObservableCollection during the initialization I am utilizing a DataTemplateSelector to choose between two datatemplates for two different scenarios. If the Value property has a value then template A should be used to present the Cell class. However if the Value property is null Then template B should be used to present the Cell class. While this works perfectly fine during the initialization however during the runtime the templates don't change any more when the value of the Value property actually changes. Is the approach of using DataTemplateSelector the wrong approach to change DataTemplates dynamically? What would you recommend I should do? Many thanks,

  • Reliable and fast way to convert a zillion ODT files in PDF?

    - by Marco Mariani
    I need to pre-produce a million or two PDF files from a simple template (a few pages and tables) with embedded fonts. Usually, I would stay low level in a case like this, and compose everything with a library like ReportLab, but I joined late in the project. Currently, I have a template.odt and use markers in the content.xml files to fill with data from a DB. I can smoothly create the ODT files, they always look rigth. For the ODT to PDF conversion, I'm using openoffice in server mode (and PyODConverter w/ named pipe), but it's not very reliable: in a batch of documents, there is eventually a point after which all the processed files are converted into garbage (wrong fonts and letters sprawled all over the page). Problem is not predictably reproducible (does not depend on the data), happens in OOo 2.3 and 3.2, in Ubuntu, XP, Server 2003 and Windows 7. My Heisenbug detector is ticking. I tried to reduce the size of batches and restarting OOo after each one; still, a small percentage of the documents are messed up. Of course I'll write about this on the Ooo mailing lists, but in the meanwhile, I have a delivery and lost too much time already. Where do I go? Completely avoid the ODT format and go for another template system. Suggestions? Anything that takes a few seconds to run is way too slow. OOo takes around a second and it sums to 15 days of processing time. I had to write a program for clustering the jobs over several clients. Keep the format but go for another tool/program for the conversion. Which one? There are many apps in the shareware or commercial repositories for windows, but trying each one is a daunting task. Some are too slow, some cannot be run in batch without buying it first, some cannot work from command line, etc. Open source tools tend not to reinvent the wheel and often depend on openoffice. Converting to an intermediate .DOC format could help to avoid the OOo bug, but it would double the processing time and complicate a task that is already too hairy. Try to produce the PDFs twice and compare them, discarding the whole batch if there's something wrong. Although the documents look equal, I know of no way to compare the binary content. Restart OOo after processing each document. it would take a lot more time to produce them it would lower the percentage of the wrong files, and make it very hard to identify them. Go for ReportLab and recreate the pages programmatically. This is the approach I'm going to try in a few minutes. Learn to properly format bulleted lists Thanks a lot.
