  • Django templates tag error

    - by Hulk
    def _table_(request,id,has_permissions): dict = {} dict.update(get_newdata(request,rid)) return render_to_response('home/_display.html',context_instance=RequestContext(request,{'dict': dict, 'rid' : rid, 'has_permissions' : str(has_permissions)})) In templates the code is as, {% if has_permissions == "1" %} <input type="button" value="Edit" id="edit" onclick="javascript:edit('{{id}}')" style="display:inline;"/>&nbsp;&nbsp;&nbsp;&nbsp; {% endif %} There is a template error in has_permissions line. Can any 1 tell me what is wrong here. has_permissions has the value 1 or 0.

  • Syncing two separate structures to the same master data

    - by Mike Burton
    I've got multiple structures to maintain in my application. All link to the same records, and one of them could be considered the "master" in that it reflects actual relationships held in files on disk. The other structures are used to "call out" elements of the main design for purchase and work orders. I'm struggling to come up with a pattern that deals appropriately with changes to the master data. As an example, the following trees might refer to the same data: A |_ B |_ C |_ D |_ E |_ B |_ C |_ D A |_ B E C |_ D A |_ B C D E These secondary structures follow internal rules, but their overall structure is usually user-determined. In all cases (including the master), any element can be used in multiple locations and in multiple trees. When I add a child to any element in the tree, I want to either automatically build the secondary structure for each instance of the "master" element or at least advertise the situation to the user and allow them to manually generate the data required for the secondary trees. Is there any pattern which might apply to this situation? I've been treating it as a view problem, but it turns out to be more complicated than that when you look at the initial generation of the data.

  • How do I set a time in a time_select view helper?

    - by brad
    I have a time_select in which I am trying to set a time value as follows; <%= f.time_select :start_time, :value => (@invoice.start_time ? @invoice.start_time : Time.now) %> This always produces a time selector with the current time rather than the value for @invoice.start_time. @invoice.start_time is in fact a datetime object but this is passed to the time selector just fine if I use <%= f.time_select :start_time %> I guess what I'm really asking is how to use the :value option with the time_select helper. Attempts like the following don't seem to produce the desired result; <%= f.time_select :start_time, :value => (Time.now + 2.hours) %> <%= f.time_select :start_time, :value => "14:30" %>

Could somebody explain how? note, I edited the question before posting the solution.

  • SQL Join a View with a Table

    - by gamerzfuse
    CREATE VIEW qtyorderedview AS SELECT titleditors.title_id, titleditors.ed_id, salesdetails.title_id, salesdetails.qty_shipped FROM titleditors, salesdetails WHERE titleditors.title_id = salesdetails.title_id I am using the above SQL statement to create a view. I need to show Editors First Name, Last Name, City where they shipped more than 50 books. The three tables I have are: create table editors ( ed_id char(11), ed_lname varchar(20), ed_fname varchar(20), ed_pos varchar(12), phone varchar(10), address varchar(30), city varchar(20), state char(2), zip char(5), ed_boss char(11)); create table titleditors ( ed_id char(11), title_id char(6), ed_ord integer); create table salesdetails ( sonum integer, qty_ordered integer, qty_shipped integer, title_id char(6), date_shipped date); Can anyone tell me what the second Join code would be to create this result? My first view works fine, but I don't know how to join it to the second table to achieve this result? I didn't make the tables, I just have to work with what I was given. Thanks in advance!

  • Drupal Customizing User Registration Form

    - by Asif Mulla
    Hi All, I am newbie in Drupal 6. I am looking for customizing User registration form. Apparently found that while adding user using Admin login allows registration form to have fields like email address, username, password,confirm password, etc with validations. But when anonymous use wants to register, then only fields like email address and username are displayed. I tried with Profile module available. But now how could I add some fields (password, confirm password, terms & condition check and receive news letter check box)and behavior (password, confirm password validation etc.)? If I am adding such fields they are also get visible in AdminAdd user form resulting duplicate fields like Password,Confirm password. Could you please suggest me how can I do this? I tried googling but confused me a lot as I am beginner to Drupal.

  • How to set multiple permissions in one class view, depending on http request

    - by andrew13331
    How can I change the permissions depending on if it is a get or a post. Is it possible to do it in one class or would I have to separate it out into two classes? If its a get I want "permission_classes = (permissions.IsAuthenticated)" and if its a post I want "permission_classes = (permissions.IsAdminUser)" class CategoryList(generics.ListCreateAPIView): queryset = QuestionCategory.objects.all() serializer_class = QuestionCategorySerializer permission_classes = (permissions.IsAuthenticated,)

  • Html.ActionLink in Partial View

    - by olst
    Hi. I am using the following code in my master page: <% Html.RenderAction("RecentArticles","Article"); %> where the RecentArticles Action (in ArticleController) is : [ChildActionOnly] public ActionResult RecentArticles() { var viewData = articleRepository.GetRecentArticles(3); return PartialView(viewData); } and the code in my RecentArticles.ascx partial view : <li class="title"><span><%= Html.ActionLink(article.Title, "ViewArticle", new { controller = "Article", id = article.ArticleID, path = article.Path })%></span></li> The problem is that all the links of the articles (which is built in the partial view) lead to the same url- "~/Article/ViewArticle" . I want each title link to lead to the specific article with the parameters like I'm setting in the partial view. Thanks.

  • Django Threaded Commenting System

    - by Yasin Ozel
    (and sorry for my english) I am learning Python and Django. Now, my challange is developing threaded generic comment system. There is two models, Post and Comment. -Post can be commented. -Comment can be commented. (endless/threaded) -Should not be a n+1 query problem in system. (No matter how many comments, should not increase the number of queries) My current models are like this: class Post(models.Model): title = models.CharField(max_length=100) content = models.TextField() child = generic.GenericRelation( 'Comment', content_type_field='parent_content_type', object_id_field='parent_object_id' ) class Comment(models.Model): content = models.TextField() child = generic.GenericRelation( 'self', content_type_field='parent_content_type', object_id_field='parent_object_id' ) parent_content_type = models.ForeignKey(ContentType) parent_object_id = models.PositiveIntegerField() parent = generic.GenericForeignKey( "parent_content_type", "parent_object_id") Are my models right? And how can i get all comment (with hierarchy) of post, without n+1 query problem? Note: I know mttp and other modules but I want to learn this system. Edit: I run "Post.objects.all().prefetch_related("child").get(pk=1)" command and this gave me post and its child comment. But when I wanna get child command of child command a new query is running. I can change command to ...prefetch_related("child__child__child...")... then still a new query running for every depth of child-parent relationship. Is there anyone who has idea about resolve this problem?

  • Drupal: Content in blocks from node_reference fields?

    - by Marco
    After only a few weeks of working with Drupal I've come up with a recurring problem, which I don't really have an optimal solution to, so I'm hoping that someone here might be able to give some best practice pointers. What I have is a region inside my node.tpl.php, which is populated with blocks that display content from two different CCK fields of the type node_reference. This works fine when displaying a single node. The problem appears when I need to use a view. For example, lets say I have a news listing, and a single news item view. When I display the single news item I can use the news node node_reference field to reference whatever material I would like to have in my sidebar, but when on the news listing view I would like to reference nodes separately. What would be the best practice to solve this? I'm having a few ideas, but none seem like the logical choice, how would you do?

  • Best way to create preview functionality in Rails

    - by slythic
    Hi all, I'm looking to implement preview functionality in my posts scaffold. All I need to do is allow a user to enter information in the new view (/posts/new) and then replace the submit button with a preview button. Once the preview button is clicked, the user is routed to the preview page (probably /posts/new/preview). If the user wants to make a change they would click 'go back' or if they are happy with the post they can then submit the post. I found this article (http://eyedeal.team88.org/node/105) but it seems dated. Any ideas on what the best approach for this would be? Many thanks, Tony

  • What's an elegant way to conditionally add a class to an HTML element in a view?

    - by ryeguy
    I occasionally have to add a class to an html element based on a condition. The problem is I can't figure out a clean way of doing it. Here's an example of the stuff I've tried: <div <%= if @status = 'success'; "class='ok'"; end %>> some message here </div> OR <% if @status == 'success' %> <div class='success'> <% else %> <div> <% end %> some message here </div> I don't like the first approach because it's crowded looking and hard to read. I don't like the second approach because the nesting is screwed up. It'd be nice to put it in the model, (something like @status.css_class), but that doesn't belong there. What do most people do?

  • Loading an OverlayView from XIB -vs- programmatically for use with UIImagePickerController

    - by PLG
    I am currently making a camera app for iPhone and I have a strange phenomenon that I can't figure out. I would appreciate some help understanding. When recreating an overlay view for passing to UIImagePickerController, I have been successfully been able to create the view programmatically. What I haven't been able to do is create the view with/without controller in IB, load it and pass it to the overlay pointer successfully. If I do it via IB, the view is not opaque and obscures the view of the camera completely. I can not figure out why. I was thinking that the normal view pointer might be assigned when loading from XIB and therefore overwrite the camera's view, but I have an example programmatically where view and overlayView are set equal in the controller class. Perhaps the load order is overwriting a pointer? Help would be appreciated... kind regards.

  • Edit and Create view using EditCreate.ascx partial in ASP.NET MVC

    - by mare
    If you look at the NerdDinner example of creating and editing dinners then you see they use a partial (ViewUserControl or ASCX) DinnerForm to put the functionality of creating and editing dinners into one file because it is essential the same and they use it using RenderPartial("DinnerForm"). This approach seems fine for me but I've run into a problem where you have to add additonal route values or html properties to the Form tag. This picks up the current action and controller automatically: <% using (Html.BeginForm()) { %> However, if I use another BeginForm() overload which allows to pass in enctype or any other attribute I have to do it like this: <% using ("Create", "Section", new { modal = true }, FormMethod.Post, new { enctype = "multipart/form-data" })) and as you can see we lose the ability to automatically detect in which View we are calling RenderPartial("OurCreateEditFormPartial"). We can't have hardcoded values in there because in Edit View this postback will fail or won't postback to the right controller action. What should I do in this case?

  • ASP.NET MVC Populating a DropDownList with a value from the view

    - by lomaxx
    In my controller I have this: ViewData["maskList"] = new SelectList(equipmentRepository.GetMasks(), "Id", "DisplayName"); and then I bind it to my view using <div each="var nfa in mfa.NasalFittingAssessment"> ${Html.DropDownList("NasalMaskTypeId", ViewData["maskList"] as IEnumerable<System.Web.Mvc.SelectListItem>, new { class = "ddl" })} </div> Note that I'm using the spark view engine so this DropDownList is getting rendered to the page via a loop. This means that the selected value of the dropdown list will change on each iteration of the loop. What I can't work out is how to pass in the value I want to set the DropDownList to based on the value that is currently being rendered to the screen.

  • Canonical resource for forms-based design in ASP.NET MVC?

    - by Robert Harvey
    Is there a resource on the web that describes various form scenarios in ASP.NET MVC, and gives example solutions within a sensible, consistent design philosophy? Examples of such scenarios might be: One-to-many forms, like invoice data-entry forms. Foreign-table forms such as Add New User in a form that requires specifying a user Forms that require dynamic interaction, using Ajax or JSON. Popup forms Forms requiring multiple data records to be input, without postbacks. Note that there is considerable conceptual and technological overlap among these example scenarios. I am aware that there is a vast patchwork quilt of available technologies and examples out there that provide partial solutions and pieces of solutions, such as jQuery Ajax, CSS, and so forth. But I would like guidance in using these technologies in more effective and consistent ways. I am not considering web forms integration with an ASP.NET MVC application; I would still like my applications to be pure MVC. Nor am I, at the moment, considering a paid solution like Telerik. But I would like to know if someone has already done some of the work combining these technologies into a consistent, cohesive whole, that follows a sensible design philosophy. (an open source framework, perhaps?)

  • Need some serious help with self join issue.

    - by kralco626
    Well as you may know, you cannot index a view with a self join. Well actually even two joins of the same table, even if it's not technically a self join. A couple of guys from microsoft came up with a work around. But it's so complicated I don't understand it!!! The solution to the problem is here: http://jmkehayias.blogspot.com/2008/12/creating-indexed-view-with-self-join.html The view I want to apply this work around to is: create VIEW vw_lookup_test WITH SCHEMABINDING AS select count_big(*) as [count_all], awc_txt, city_nm, str_nm, stru_no, o.circt_cstdn_nm [owner], t.circt_cstdn_nm [tech], dvc.circt_nm, data_orgtn_yr from ((dbo.dvc join dbo.circt on dvc.circt_nm = circt.circt_nm) join dbo.circt_cstdn o on circt.circt_cstdn_user_id = o.circt_cstdn_user_id) join dbo.circt_cstdn t on dvc.circt_cstdn_user_id = t.circt_cstdn_user_id group by awc_txt, city_nm, str_nm, stru_no, o.circt_cstdn_nm, t.circt_cstdn_nm, dvc.circt_nm, data_orgtn_yr go Any help would be greatly apreciated!!! Thanks so much in advance!

  • Weird ViewControllers - iPhone SDK

    - by Kevin
    Hello everyone, I have a Tab-Bar Application for this iPhone application I am making. I make a simple button on the 3rd view (3rd tab), and give it an IBAction to give an alert view. When I press build and go, everything works out fine. I go onto the 3rd tab, and I press my button. It simply crashes... Why is this happening? Everything I put in this 3rd tab crashes. I create a simple view controller, and write the class files to start over, but I keep getting the same errors.. Everything works fine on my first tab, where I originally got the first view controller.. P.S It also says Incomplete Implementation of Class 'ThirdViewController'. I don't know why its there.. If anyone can help me out here, i would greatly appreciate it. Kevin

  • How do I return JSON data from a partial view FormMethod.Get?
