Is it possible to set the absoluteURI in the controller after clicking on an action link? So for example:
User clicks on a link called "GoHere". The current URL is domain.com/section/place. When the link hits the method in the controller, it recognizes that the user is currently in a section called "section", even though in the file structure section doesn't exist. The link itself actually points to domain.com/place2. Instead of returning a URL of domain.com/place2, it returns domain.com/section/place2.
The reason I ask is because for what I'm doing, the section is completely arbitrary and doesn't exist. It's just there to give the impression that the user is in another section. I know I could create extra sets of controllers, but I'm trying to get around this since for management purposes it's better if I just have one set of controllers. Is this possible? Thanks.
In your gobal.asax, try setting your route to require section for the control. Maybe "{control}/section/{action}/" and whatever else you need.

I'm trying to internationalise my app, and I want to set T.set_current_languages('en', 'en-en') as described in the docs. But it's unclear to me which file to place this in. Can I just stick it in e.g. db.py? Or at the top of default.py?
If you want the setting to apply to all requests, then put it in a model file (e.g., db.py, as you suggest). If you put it at the top of the default.py controller, it will apply only to requests made to the default controller.
I suspect I'm doing this wrong.
For various reasons, my app forces the user to make some choices right after login. In order to ensure that they enter the necessary data, I override the OnActionExecuting method in a base controller class to intercept any attempt at executing an action before this data has been entered, and redirect the user to the necessary page. I preserve the url of the action they were attempting to execute with the following code:
url = Url.RouteUrl("Default", filterContext.RouteData.Values);
(filterContext is an ActionExecutingContext object, and a parameter of OnActionExecuting.)
The problem I'm having is that, if the action was associated with a controller in an area, the url I get doesn't reflect the area.
I understand from other posts that I can get the area name from the DataTokens collection of RouteData. But I'm uncertain of the best way to pass it. I suppose I could retrieve it and use the RouteValueDictionary.Add method to add it to RouteData.Values (assuming Values is not read-only at that point; I don't know), but that feels a bit ... odd, like somehow the point is being missed.
Is this really the way this is supposed to be done? Is there something wrong elsewhere, that Area is absent from my RouteData.Values?
I would just take it out of the data tokens in the filter and add it to route values. You can do it with RouteValues.Add:
if (filterContext.RouteData.DataTokens.ContainsKey("area"))
filterContext.RouteData.Values.Add("area",
filterContext.RouteData.DataTokens["area"]);
The areas feature was added in MVC2, and I imagine this is a side effect of it not being in MVC1. However, as long as your RouteValues contains an "area" key, UrlHelper.RouteUrl should generate the correct URL for the area.
I have some property OwnerId that has each page in my application. I need these property to create HttpWebRequest and get some data. But when the application deactivated and activated again the page as deleted and created again, so these property is 0. I can't save these property in PhoneApplicationPage.State , because these property is different for different pages, so when I go twice back I can get error. I think to take it property after application activated from NavigationService.BackStack pages.But I'm not sure it is right. How can I do it ?
Aram .. thanks for explaining the question better.
Now, while your application is in the foreground, how are you managing all these different OwnerIDs? A collection? I am guessing you don't have multiple instances of the same page; but rather pass query parameters along to indicate which OwnerID/UserID should be used to display appropriate user info. You could put the whole collection in State dictionaries with a key & hydrate/dehydrate during the application lifecycle. Makes sense?
Thanks!
I'm not 100% clear on whether you need a setting for each page or just a single setting for the app. In either case your best option (IMO) is IsolatedStorageSettings (http://msdn.microsoft.com/en-us/library/system.io.isolatedstorage.isolatedstoragesettings(v=vs.95).aspx)
If you just need a single setting then there's no problem but if you need one for each page you will need to do something ugly like using the page name as the key.
I know that we can design the layout in *.xml then in the action just invoke loadLayout, and renderLayout to render the blocks/views.
But, I have a question is:
- How can I load the layout at runtime?
If we have an action which does not really design its layout and will be decided how to render at runtime.
You can please consider the answer from the question for more clear.
Writing a new answer because it seems that you actually DO still want to render, you just want to render a different route's layout XML updates. I believe the _forward() method from Mage_Core_Controller_Varien_Action will allow you to do what you are describing with the least amount of pain.
You should add your action controller directory ahead of the catalog directory, create a ProductController with a viewAction, and check customer is not logged in - in this check you would call $this->_forward('customer','account','login');.
This approach though is going to require more effort in order to be usable, as I imagine that you want the user to be sent to the product page upon login. Have you seen Vinai Kopp's Login Only Catalog module? It should do this for you.
loadLayout() and renderLayout() just execute block output method toHtml() (usually) and take the resulting strings and apply them to the response object via appendBody(). In an action controller you can just call $this->getResponse()->setBody('response string'). How you build the string is up to you.
You can also use Mage_Core_Block_Flush to immediately send output to the browser without using the response object.
I'm using a web application project.
I have a folder in my web root called Users and in the folder I have a page called UserList.aspx
What I want to be able to do is type in Response.Redirect(Users.UserList.URL)
What I reckon I can probably do is create a class that extends Page and add a static property called URL that calls MethodInfo.GetCurrentMethod().ReflectedType (I think this works haven't tested) and then have that convert Users.UserList -> ~/Users/UserList.aspx
The problems with this method that I know of are one I need to go through every page and make it extend the base class and it doesn't work with any pages that contain a '-' character.
The advantages are that if pages are moved around then there aren't any broken links (Resharper gives out when there is a Page with the wrong namespace).
Also then every individual page that takes query string params could have a static method so that if I want to add/remove params I can see what uses those params etc.
Also if I want to call that page I don't have to check the name of the params e.g. UserId userId, Id or id. So that would look something like Users.ViewUser.GetUrl(1) -> ~/Users/ViewUser.aspx?UserId=1
So the question is: Is there a better way of doing this? Or is this a bad idea in principal?
You could just create an extension method for the base Page class that does what you are thinking. That would avoid having to go back and modify the base class for all your pages.
There is a better way. Create a traffic cop that knows about paths. Then if paths change, your data model changes or other stuff you just change that one place. Plus you could have read from a config file and make changes at run time.
Thus your call looks like this:
Repose.Redirect(TrafficCop["Users.UserList"].URL)
or some other way if you don't like the syntax.
The MethodInfo.GetCurrentMethod().ReflectedType doesn't work so I came up with another method of doing this using generics.
Instead of Users.ViewUser.GetUrl() or Users.ViewUser.URL it's GetUrl()
For a page with parameters it's still Users.ViewUser.GetUrl(1), it isn't ideal because they should both have the same way of being called but better than strings I guess.
Going to leave the question open for a while just in case.
edidt: I think I will actually just create another method called GetUrl(String getQuery) because if I have two parameters that are of the same type it doesn't work very well.
further edit: I found out how to do exactly what I want to do.
created a class called BasePage:Page where T : Page
on that are the static methods redirect and geturl
each page inherits from the base page as follows: MyPage:BasePage
Any page can redirect to that page by using the command MyPage.Redirect();
