2sxc 13 - Get username and other DNN tokens in formulas/calculations - dotnetnuke

Is there a way to get the current username in a formula (the v1(data, context) new stuff)? And other DNN tokens as we would on a view.
Current date is easier, since it dependends only on c#, but I can't any documentations for username.

If you are working with Razor templates, yiu can call and and all DNN methods. Also, while editing a template, the dark left column of the edit screen gives you access to all sorts of snippets that you can use by clicking on them.

This feature is still experimental and doesn't do much outside of its context in the browser. We've done a few tests and could not reach outside the Angular app's scope (which makes sense). I do believe there are plans wire up things like that. Daniel will probably chime in.
In the mean time, there is no reason you can't write your own API to get the answers you need from the backend. The formulas aren't limited in any way, so there is no reason not to do it like this (assuming writing your own C# 2sxc WebApi code is something you are familiar with):
async function api()
{
let tmp = await sxc.webApi.fetchJson('/api/2sxc/app/myapp/api/score/progress');
console.log(JSON.stringify(tmp));
}

Just fyi: 2sxc 13.10.02 will have a context.sxc which is great for calling APIs, as well as a context.user.id which will give you some user info. Using this you should be able to get this to work.

How can I use DNNSharp MyTokens in 2SXC Razor templates?

I have a content type and C# Razor template for a simple page hero built using 2SXC. I also have a DNNSharp MyTokens with a simple token that looks like this: [DBQ:EligibleForExam]
Using the regular DNN HTML module, I can put my token in the source and it renders the value of the token.
I want to display the value of this DNNSharp MyToken inside of the C# Razor template but it doesn't show the value. Furthermore, I want to perform an if else statement on this value.
Here's what I want to do:
#if [DBQ:EligibleForExam] = 1 {
<p>You are eligible for the exam</p>
}
How can I use DNNSharp MyTokens in 2SXC?
In this case you can choose between going all the way 2sxc or all the way DNNSharp :
- scenario 2sxc: translate the DNNSharp token to 2SXC. I don't know what's behind that code but I guess it is some kind of SQL select and/or filters. In 2SXC you can create content types with SQL as a source. In the query designer, you can filter these results.
- scenario DDNSharp: in MyTokens you create a razorscript or HTML and make a token out of that. I don't think you hit any barriers soon following this path.
The core problem is that tokens are not well architected in DNN, there is no officialy "global" token system which knows about the DNN Sharp tokens.
I believe it should be easy to do though: I'm pretty sure there will be some documentation on DNN Sharp how to use their tokens in any c# or MVC page. Probably just 2-3 lines of code. So best check their docs.
2SXC does not render DNNSharp tokens like html module or EasyDNNSolutions do.
It would be an awesome thing as MyTokens and 2SXC are both very powerfull.
But maybe we can fix your problem within 2SXC itself or within DNN Sharp/HTML
What are you trying to accomplish? You can share the case / code here. Or if you feel this is beyond the Q&A setup that Stackoverflow is, you can send me an email.

2sxc - Getting URL path from DNN link parameter / Tab ID

I am working on integrating a 2sxc content WebAPI feed into a ReactJS application.
I have managed to get a JSON feed of data into the application, and am in the process of mapping out the data.
I'm wondering what the best practice would be to "resolve" a URL which is coming through as a DNN Page/ Tab ID.
Below I will showcase the various points this is referenced...
First the Setup of the entity / data types...
Then this is an example entry with the data filled out... The page link / URL is set up to point to another internal page on the DNN website:
Finally you can see this data item come through as a JSON feed via the 2sxc API:
What is the best way to convert this piece of data into a URL which can be used in a SPA type application?
There isn't any "server-side" code going on, just reading a JSON feed on the client side...
My initial idea would be to parse this piece of data in JS, to extract the number then use something like this:
http://www.dotnetnuke.com/tabid/85/default.aspx
http://www.dotnetnuke.com/default.aspx?tabid=85
I was hoping someone with more experience would be able to suggest a better / cleaner approach.
Thanks in advance
If you were server-side in Razor you'd be doing something like this:
#using DotNetNuke.Common
View List
XXXX = Dnn.Tab.TabID or define a string with the tab id you want
I seem to have a vague memory that I saw somewhere that Daniel (2sxc) has a way to use Globals.NavigateUrl() or similar on the client side, but I have no idea where or if I did see that.
The Default.aspx?tabid=xx format will certainly work, as it's the oldest DNN convention and is still used in fallbacks. The urls aren't nice, but it's ok.
The reason you're seeing this is because the query doesn't perform the automatic lookup with the AsDynamic(...) does for you. There is an endpoint to look them up, but they are not official, so they could change and therefor I don't want to suggest that you use them.
So if you really want a nicer url, you should either see if DNN has a REST API for this, or you could create a small own 2sxc-api endpoint (in the api folder) just to look that up, then using the NavigateURL. Would be cool if you shared your work.

Can a site visitor alter AngularJS property names?

I have a function in the back-end that relies on the property names of an object, which is sent using AJAX with AngularJS. Can a user alter the property names using a debug tool, therefore changing what I would normally expect in the back-end? I suppose doing that would also affect the entire app in general if it was possible.
I guess it's kind of like someone using a debug tool to change the name attribute on a form and then submitting it. So I was curious to know if it's something I should ever keep in mind for AngularJS. I hope that makes sense.
If user is smart enough, he or she can change mostly everything using developer tools browser brings. What is more, if back-end endpoint is known, it easy to mock custom request with custom data.
You should always validate request since everything what doesn't come directly from your code can lead to security break.
The big downside of Ajax is that its requests are easily debugged using dev tools and, if are not designed correctly, expose your internal structures.

Single Page App without URL

I'm joining a team that is currently working on a single page app. It is written with AngularJS, but it doesn't matter for the topic.
The App is so complex (many independant views with complex different states within each) that they completly removed the router (well, excerpt the default route).
I'm googling around but I can see no example of webapp that is not trying to work properly with URLs. Is there any risk of not using any URL, beyond the fact that "it is not the elegant way" ?
EDIT : ui-router does not fit, because of this issue : https://github.com/christopherthielen/ui-router-extras/issues/90
It sounds like you want to look into something like UI-Router which works on states.
https://github.com/angular-ui/ui-router
I can't imagine any significant issues with your app if you do it this way, but I can see massively bloated controllers and code to try and get around any issues you find.
as #Varedis said, you can use ui-router, but to answer your actual question, consider the use case for urls.
If you have only one url, there's only one entry point into your app. This can be annoying if the user expects to be able to quickly go to a certain area (state) within your app. Only one url means that the user can't bookmark, directly go to, or find with a search engine, any specific part of your application.
You can use other mechanisms like cookies or LocalStorage to keep track of state, but these are less user-visible.
I work on the project and i founded a month ago, ui-router-extras which provide parralel states but it can't instiante more than one state instance.
Is there another solution to do that ?

ASP.NET 3.5 webforms URL Routing question

I'm attempting to configure URL routing in my ASP.NET 3.5 WebForms app. Setting up routes has always been confusing to me, so I was hoping I could get some direction.
My requirement is fairly simple. I'm setting up different "brands" of my application, and I'd like the brand to be specified in the URL. For example, http://www.mysite.com/brand1/Default.aspx would bring up one brand (code behind would look up brand1 in the db and load specific text, images, themes, etc) and http://www.mysite.com/brand2/Default.aspx would bring up another brand, etc.
I'm fairly flexible with how the URLs are displayed, with the exception of keeping the http://www.mysite.com/brand1 prefix. That cannot be changed.
Thanks for any help!
I do this by using http://www.UrlRewriter.net, as explained here by Scott Gu:
http://weblogs.asp.net/scottgu/archive/2007/02/26/tip-trick-url-rewriting-with-asp-net.aspx
The trick is to use URL rewriting rules (Regular Expressions) in your web.conifg to get a request for /brand1/default.aspx to actually execute /Processor/Default.aspx?brand=brand1, for example.
NB: The Form.browser trick worked a treat for me when doing postbacks.
Another possible answer from me...
If you're using IIS 7 there is a handy built in module for URL Rewiring, all controlled through a GUI if that's your preference:
