I am trying to use Django formsets to present two or more specific role types on the same HTML template. For example I have a hierarchy of players on a an 11 player soccer team and a couple of coaches. I want the head coach then the assistant coach to be collected on the template and subsequently the players starting with goalie until player number 11.
I am planning on using a teammembers = formset_factory(MemberForm, max_num=14) formset and then organizing the form instances as accordingly into coaches section, players section, etc. What I am struggling with is whether my view and template can use something like; if form in formsets = form[x]:do something. Can someone help?

I have various templates like sms.birthday and sms.account-created. They all inherit from a base view layouts.sms. On one of the admin pages, I wanted to show a preview of these views by including them with some dummy data. However, when including the views, the first one that is included overwrites the sections of all other views.
// layouts.sms
#yield('sms.content')
// sms.birthday
#extends('layouts.sms')
#section('sms.content')
Happy birthday
#stop
// sms.account-created
#extends('layouts.sms')
#section('sms.content')
Account created
#stop
// admin page
#include('sms.birthday')
#include('sms.account-created')
Expected results on admin page:
Happy birthday
Account created
Actual results on admin page:
Happy birthday
Happy birthday
Instead of using #stop, using #overwrite solves my issue.

I have an application where I need to display metrics. The application needs to display a separate vertical section for each metric. When I started this, there were only 5 metrics so I naively created a template with 5 regions, one for each metric I needed to display. Now, new metrics need to be added and I want to avoid adding "hardcoded" region divs in the template. I want to refactor this and create the required regions dynamically at startup time based on some configuration data.
So I have been looking at the latest Marionette release and in question "Dynamically add regions to Marionette layout", Derick Bailey mentions that Marionette v1.0 supports dynamic regions in Layouts through addRegion(), as in:
var layout = new MyLayout();
layout.render()
layout.addRegion("someRegion", "#some-element");
layout.someRegion.show(new MyView());
I have tried that in my code (using Marionette 1.0.2) and I am not getting it to work. I don't have a div with id="some-element" in my template and I suspect this could be the reason. I was hoping that Marionette would create that div itself.
Perhaps my expectation of what dynamically adding a region means is wrong. So my first question is: when adding regions dynamically to a layout, must the element id passed in the addRegion() function already exist in the layout?
If so, then I am back to the problem of having to "burn" in the template those divs for the regions to attach themselves too. My follow-up question is then: What is the best way of doing this in a data-driven fashion? Is it a matter of writing my own render() function so that the right set of divs get created? Or perhaps providing my Layout with a model object that will contain data which the template can then iterate through to create the necessary divs? How do we add regions dynamically to a Layout object if we don't know in advance how many regions we will actually need?
Aa #aaronfay specified, we need to use jQuery to create the element on the page. Here is some sample code:
var layout = new MyLayout();
layout.render()
var regionName = "dynamicRegion";
layout.$el.append('<div id="'+regionName+'"></div>');
layout.addRegion("someRegion", "#"+regionName);
layout.someRegion.show(new MyView());
I believe you would need to use jQuery (or similar) to create the element on the page. A Region expects the element to exist.
Otherwise, I believe your answer is here.
I'm trying to render a view, defined in a module, in the main site homepage (~/) as it's main content. If the user is not authenticated, i need to show a login/register view instead.
The logged-in view lives in one module (Product Module) and the login/register view lives in another (Account Module). The logged-in view requires a service call to fetch data based on the user's products. I'm currently using standard mvc to render these views and fetch the data they require in their controllers.
Can this be accomplished by treating these views as shape templates? If so, are there any examples of pulling in views to the homepage like this? Or is there a better way of achieving this?
I have tried implmenting IHomePageProvider to return my own homepage ViewResult within the Product module, but without any success.
Cheers.
First, you might want to look into widgets and layers. You could define a layer for authenticaed users, and one for anonymous users, and attach widgets to those layers to achieve what you want. That might be the best way for you to accomplish this. Look in the Orchard docs for examples on how to do this.
I have done a similar thing before using custom controller and a lot of custom logic. Because of my specific requirements widgets and layers would not work for this. All the content on the page needed to change depending on some inputs, and widgets and layers were not going to be well suited for this. What I did was create a custom controller, and a corresponding Route with a high priority (so the Route takes precedence over any others that want to be the home page). I didn't mess with IHomePageProvider at all.
In the controller action I pulled the data necessary, and created the shapes I wanted, and then returned a result like this: return new ShapeResult(this, homePageShape);
homePageShape is constructed like this, right before the return statement:
// Create personalized home page shape:
var homeShape = _orchardServices.New.CustomHome(
SomeShape1: someShape1
, SomeShape2: someShape2
, SomeModel1: someModel1
...
);
This creates a shape called CustomHome, and orchard will automatically look for a template called CustomHome.cshtml in the views folder of your module.
I created several shapes (all the "someShapeX" vars you see above). Mostly they are created from content parts via the BuildDisplay() method. The content parts are queried using IContentManager, and the shapes are created like this (this example is for a slide show shape):
dynamic sliderShape = _contentManager.BuildDisplay(sliderPart, "Detail");
You can put logic in the controller to build the shapes you want depending on whether or not the user is logged in. In CustomHome.cshtml you would render a shape like this:
#Display(Model.SomeShape1)
I'm new to MVC3 (and MVC in general) and looking for a bit of advice. Pointing me in the direction of some good articles or tutorials would be good enough I think. I'm a bit familiar with the concept of MVC, and I've been a c# programmer (hobbyist and partly professional) for a while now.
The issue I have is that I have an object (call it "Game"), which has a List<T> as a property (call T "Player"), and I want the user to "select" the player to add them to the Game.
All players would be managed in another part of the application, so there is no need to think about "managing" the master player pool at this point.
I'm looking for a best practice for:
adding custom objects to a list that of n length while on a page.
Searching for and selecting a custom object in the first place.
I can do the standard pages for the database access so that's not a problem. In asp I would have just done something like a wizard and managed everything through postback on the page, but I want to try and keep to best practice where i can for this project.
Any pointers welcome, also looking for some good physical books to buy on MVC.
If I understand you correctly you want two elements within the page, a player search (over all players) and a list of players already added to the game.
For the player search you want to use a bit of jQuery to hook up an actionResult that returns a JSON result of your player results. You can then display these results without having to leave the page, in appearance much like an AJAX post in webforms.
You have more options for how you add the player to the game, depending on if you want to add more than one at once, or want a backout stage (so you can "add" players and then cancel out and they won't be added).
the option I think would give the most seamless interface would be a jQuery/javascript call to an action method which datawise adds your player to the game, and use jQuery to add the element to your players in the game on the page.
For the adding of a player in your controller you could return a bool in a JSON result, just you have confirmation that the player was successfully added to the list.
For reference: This is quite an old article but highlights the power of working with jQuery and MVC quite nicely I think http://andreasohlund.net/2008/12/21/asp-net-mvc-jquery-true/
I'm using BEA's Publisher product with ALUI. I want to have a simple portlet that just displays Content Items that I've published, but after playing with it for a couple of hours, I find myself stuck.
I have a Data Entry template that just takes a name and a file, and a presentation template associated with that. But I can't figure out how to make the presentation template display a list of published content items associated with the Data Entry template.
I tried using the Tag Helper and I saw that the file properties were available, e.g. name, location, length, however I can't get the template to actually display the information.
Also, since I can't publish said presentation template (you aren't allowed to publish a presentation template associated with a data entry template), I have to make ANOTHER presentation template, and include the first one, and then make a new portlet that displays that second template. Is this how it's supposed to work? It seems awfully complicated for such a simple task.
I would greatly appreciate any input anyone can give. Thanks!
