I am writing velocity templates for my liferay theme and I am wondering, whether it is possible to create a new object inside the velocity template.
The reason is that in liferay there is no contextTool registered in the context and I really want to be able to inspect the variables that are present in the template at a given time.
There is a cool macro for this, but unfortunately it uses the contexttool.
I'd like to do something like:
#set($contextTool = new ContextTool())
Another solution would be java code that is provided with the liferay theme that is able to add stuff in the template context. But I don't know how this would work either... ;-)
try with
#set($contextTool = $portal.getClass().forName("full.package.ContextTool").newInstance())
EDIT
IF I understood you than this should give you what you want
#set($ve = $serviceLocator.findService("com.liferay.portal.kernel.velocity.VelocityEngine"))
#set($wvc = $ve.getWrappedStandardToolsContext().getWrappedVelocityContext())
#set($cVE = $portal.getClass().forName("org.apache.velocity.app.VelocityEngine"))
#set($cHSREQ = $portal.getClass().forName("javax.servlet.http.HttpServletRequest"))
#set($cHSRES = $portal.getClass().forName("javax.servlet.http.HttpServletResponse"))
#set($cSC = $portal.getClass().forName("javax.servlet.ServletContext"))
#set($cCC = $portal.getClass().forName("org.apache.velocity.tools.view.context.ChainedContext"))
#set($cVEI = $portal.getClass().forName("com.liferay.portal.velocity.VelocityEngineImpl"))
#set($cC = $portal.getClass().forName("org.apache.velocity.context.Context"))
#set($cVEU = $portal.getClass().forName("com.liferay.portal.kernel.velocity.VelocityEngineUtil"))
#set($ve = $cVEU.getMethod("getVelocityEngine").invoke(null))
#set($fVE = $cVEI.getDeclaredField("_velocityEngine"))
$fVE.setAccessible(true)
#set($cc = $cCC.getConstructor($cC, $cVE, $cHSREQ, $cHSRES, $cSC).newInstance($wvc, $fVE.get($ve), $request, $response, $request.getSession().getServletContext()))
#set($contextTool = $portal.getClass().forName("org.apache.velocity.tools.view.tools.ContextTool").newInstance())
$contextTool.init($cc)
After that you can use, for example
$contextTool.getKeys()
If this is not what you need, let me know ...

Apologies if this question has been answered elsewhere, I have had trouble finding any resources on this.
The scenario is this. I have created a custom field in the Tax Preferences screen called Usrapikey.
This value holds an api key for a call that gets done in some custom business logic.
The custom business logic however occurs on the Taxes screen.
So within the event handler I need to access that API key value from the other screen. I have tried instantiating graphs and using linq and bql but to no avail.
below is what I have currently and my error is: No overload for method 'GetExtension' takes 1 arguments
If I am going about this the wrong way please let me know if there is a more civilized way to do this
protected virtual void _(Events.FieldUpdated<TaxRev, TaxRev.startDate> e)
{
var setup = PXGraph.CreateInstance<TXSetupMaint>();
var TXSetupEX = setup.GetExtension<PX.Objects.TX.TXSetupExt>(setup);
var rateObj = GetValues(e.Row.TaxID, TXSetupEX.Usrapikey);
decimal rate;
var tryRate = (Decimal.TryParse(rateObj.rate.combined_rate, out rate));
row.TaxRate = (decimal)rate * (decimal)100;
row.TaxBucketID = 1;
}
Many Thanks!
Well, acumatica support got back. It seems if you want to access the base page use:
TXSetup txsetup = PXSetup<TXSetup>.Select(Base);
To get the extension use:
TXSetupExt rowExt = PXCache<TXSetup>.GetExtension<TXSetupExt>(txsetup);
Then you can access the extension fields like so:
var foo = rowExt.Usrfield;
I have the string with html markup, an I want to cretae Doc elment from it like this:
Doc.FromHtm "<div><p>.....</p>.....</div>"
As I understand that this is not possible right now. Ok, what is not possible to accurately sew, I tried to roughly nail using jquery:
JQuery.JQuery.Of( "." + class'name ).First().Html(html'content)
But to call this code, I need to specify an event handler for the Doc element. But it is not implemented in UI.Next.
I tried to track changes of a model with a given CSS class asynchronously:
let inbox'post'after'render = MailboxProcessor.Start(fun agent ->
let rec loop (ids'contents : Map<int,string>) : Async<unit> = async {
// try to recive event with new portion of data
let! new'ids'contents = agent.TryReceive 100
// calculate the state of the agent
let ids'contents =
// merge Map's
( match new'ids'contents with
| None -> ids'contents
| Some (new'ids'contents) ->
new'ids'contents # (Map.toList ids'contents)
|> Map.ofList )
|> Map.filter( fun id content ->
// calculate CSS class name
let class'name = post'text'view'class'name id
// change it's contents of html
JQuery.JQuery.Of( "." + class'name ).First().Html(content).Size() = 0)
// accept the state of the agent
return! loop ids'contents }
loop Map.empty )
and then, for example for one element:
inbox'post'after'render.Post [id, content]
But it is too difficult, unreliable and not really working.
Please give me an idea how to solve the problem if possible. Thanks in advance!
Just in case someone needs to use static HTML in WebSharper on the server (I needed to add some javascript to the WebSharper generated HTML page), there is fairly new Doc.Verbatim usable e.g. like
let Main ctx action title body =
Content.Page(
MainTemplate.Doc(
title = title,
menubar = MenuBar ctx action,
body = body,
my_scripts = [ Doc.Verbatim JavaScript.Content ]
)
)
Already answered this on https://github.com/intellifactory/websharper.ui.next/issues/22 but copying my answer here:
If all you want is to create a UI.Next Doc from static html you can do the following:
let htmlElem = JQuery.JQuery.Of("<div>hello</div>").Get(0)
let doc = Doc.Static (htmlElem :?> _)
This is not very nice but should work and I don't think there's a better way to do it at the moment. Or maybe you could use templating but that's not documented yet and I'm not sure it would fit your use case.
Obviously if you want to change the rendered element dynamically you can make it a Var and use Doc.EmbedView together with Doc.Static.
Today, I'm having a problem is after I had created a Calculated field. It seems there is no way to add AllContentTypes. And the DefaultView, maybe I can handle this. And I also saw this method:
spList.Fields.AddFieldAsXml(spFieldUser.SchemaXml, True, SPAddFieldOptions.AddToAllContentTypes);
But in this case, I'm not sure I can use it or not. Because my code is:
//SPField tempSPField = spList.Fields.CreateNewField(createSPColumnObject.ColumnType, createSPColumnObject.ColumnName);//We can not use this code line for creating Calculated (there is no constructor for this)
SPFieldCollection collFields = spList.Fields;
string strSPFieldCalculatedName = collFields.Add(createSPColumnObject.ColumnName, SPFieldType.Calculated, false);
if (createSPColumnObject.IsAddedToDefaultView)
{
SPView spView = spList.DefaultView;
spView.ViewFields.Add(strSPFieldCalculatedName);
spView.Update();
}
SPFieldCalculated spFieldCalculated = null;
//
spFieldCalculated = (SPFieldCalculated)collFields[createSPColumnObject.ColumnName];
spFieldCalculated.ShowInDisplayForm = true;
//spFieldCalculated.ShowInEditForm = true;
spFieldCalculated.ShowInListSettings = true;
//spFieldCalculated.ShowInNewForm = true;
spFieldCalculated.ShowInViewForms = true;
//
spFieldCalculated.Description = createSPColumnObject.ColumnDescription;
spFieldCalculated.Formula = string.Format(#"={0}",createSPColumnObject.CalcFormula);
spFieldCalculated.Update();
//spList.Fields.AddFieldAsXml(spFieldCalculated.SchemaXml, createSPColumnObject.IsAddedToDefaultView, SPAddFieldOptions.AddToAllContentTypes);// also use this code line because we will get an exception with a duplicate column ID.
spFieldCalculated.OutputType = SPFieldType.Text;
spList.Update();
I totally created a Calculated column but how can I add it to allcontent types ? everybody could help me out this ? BTW, to the DefaultView, I did like the above is right ? Could eveybody let me know this ?
I just worry about everybody get misunderstanding ? Or review with missing code. So could everybody please to take a look on my code clearly ? Thanks all.
Many thanks, :)

I'm not sure if i fully understand what you are trying to do however i may be able to shed some light on some parts of what you are trying to do.
When you create your field does it then appear in your site actions -> site settings -> Site columns. If so you have created this correctly. If it doesn't there are hundreds of examples of how to do this if you search google.
Once you have your field create you then need to consider which content types you want to add it to. Once you have these content types you then have to add something called a field link to the Content type.
This isn't my code i have picked it off the web but this should do what you require.
SPContentType ct = web.ContentTypes[contentType];
ct.FieldLinks.Add(new SPFieldLink(field));
ct.Update();

I'm creating a Sharepoint feature, this feature has an event receiver associated to it. In the event receiver, I'm creating a Document Library and Picture Library using server-side object model. I'm also adding new custom columns (around 80) to these newly created document and picture library. Now I want to modify the properties of the Description, Keywords and Title fields that are by default created along with the picture library. I want to make these fields as Required fields. How do I do this? I tried to set SPList.AllowContentTypes = true and try to change the attributes of these fields, but it doesn't work (neither gives an error nor makes these required fields). I also tried to access the content types and try to change the attributes using SPContentType.FieldsLinks["Column_name"].Required and SPContentType.Fields["Column_name"].Required but it gives me an error. Does anyone have any other suggestions?
Here is the answer....
SPContentType ct = mypiclib.ContentTypes["Picture"];
SPFieldLinks titleLink = ct.FieldLinks["Title"];
SPFieldLinks descLink = ct.FieldLinks["comments"]; //internal name of Description
SPFieldLinks keywords = ct.FieldLinks["keywords"];
titlelink.Required = true;
descLink.Required = true;
keywords.Required = true;
ct.Update();
can you tell us the error you got when trying to use the fieldlinks? Because this should work... I have done it like this:
SPContentType ct = web.Lists["*ListName*"].ContentTypes["*ContentTypeName*"];
SPFieldLinkCollection flinks = ct.FieldLinks;
flinks["*ColumnName*"].Required = true;
ct.update();
This should do the trick:
SPWeb yourWeb = ... //assign your web
SPList yourPictureLibrary = ... //assign your picture library
web.AllowUnsafeUpdates = true;
yourPictureLibrary.Fields[SPBuiltInFieldId.Title].Required = true;
yourPictureLibrary.Fields[SPBuiltInFieldId.Description].Required = true;
yourPictureLibrary.Fields[SPBuiltInFieldId.Keywords].Required = true;
yourPictureLibrary.Update();
SPAllowContentTypes isn't settable. You might try setting ContentTypesEnabled instead.
I don't have a 2010 box to test against, but if SPAllowContentTypes returns false I think you're looking at modifying the definition of your picture library in the 14 hive (TEMPLATE\FEATURES\PictureLibrary\PicLib) to get what you're after. Tread lightly there.
I have a custom view that I set up in drupal. What I would like to do is make a function call of some kind, and then assign the results to a php variable. I would like the contents of the view (as opposed to the results of a view export) in this new variable. Is this feasible? If it is a function call, I would appreciate a small example too. Thanks!
I haven't done too much hacking around in views, but it looks like maybe views_embed_view() might be what you are looking for. I found a good overview of the views API here: http://www.trellon.com/content/blog/view-views-api
You can get the view object with function views_get_view($view_name).
If what you mean by contents of the view is the view object itself you'll need simply:
$view = views_get_view('name_of_the_view');
However, if you mean the data returned by your view you'll need a little bit more.
$results = views_get_view_result('name_of_the_view', 'display_id');
At last, if you wish to have more control you can try another approach, creating the view object and working on it afterwards.
//variables for your view, display and resulting array
$my_view_name = 'yourview';
$my_display_name = 'yourdisplay';
$my_arguments = array();
//Creating the view object and configuring it
$view = views_get_view($my_view_name);
if ($my_arguments){
$view->set_arguments($my_arguments);
}
$view->get_total_rows = True;
$view->set_items_per_page(0);
$view->build($my_display_name);
$view->execute($my_display_name);
//now you have your data array
$view_results_array = $view->result;
