What method the Html.Action use for rendering a partial views ?
Example 1 (with parameters):
#Html.Action("_PartialGetMemo", "Memos", new { id = 0 })
Example 2 (without parameters):
#Html.Action("_PartialGetMemo", "Memos")
Can somone explain how this works please ?
This Html.Action renders partial view as an HTML string so we can store it in another string variable. It is string return type method so first it returns result as a string then renders result to response.

When trying to retrieve DocumentPageTitle and DocumentPageDescription using GetStringValue() on a custom page type TreeNode, the result is always coming back as the default value (in this case an empty string) passed into the method.
I'm able to successfully retrieve other column values as well as standard document properties such as DocumentName, DocumentID and AbsoluteURL, but not the document meta properties.
The respective fields in the Meta tab of document/page do have values and are being successfully rendered in the by default such as <meta name="description" content=".." />
// returns empty string
string documentPageDescription = DocumentContext.CurrentDocument.GetString("DocumentPageDescription", string.Empty);
// returns empty string
TreeNode document = parameters[0] as TreeNode;
string documentPageDescription = document.GetStringValue("DocumentPageDescription", string.Empty);
I've tried setting option Inherits fields from page type to "Page (menu item)", but that did not help.
Does the custom page type need to inherit from something specifically or have a specific setting activated to access these values? Or if what I think is a TreeNode in fact isn't, how could I get the TreeNode from this object that has the properties listed before available?
Thank you for any help you can provide.
ValidationHelper.GetString(CMS.DocumentEngine.DocumentContext.CurrentDocument.GetValue("DocumentPageDescription"), string.Empty)
Two things to check, one, are you sure the meta data is available on the page you are pulling? Two, is your API actually pulling all the data for that page?
I've used these in my test and both returned the metadata.
var page = DocumentHelper.GetDocuments().Path("/Articles/Coffee-Beverages-Explained").FirstObject;
Response.Write(page.GetStringValue("DocumentPageDescription", string.Empty));
TreeProvider tree = new TreeProvider(MembershipContext.AuthenticatedUser);
TreeNode tn = tree.SelectNodes().OnCurrentSite().Path("/Articles/Coffee-Beverages-Explained").FirstObject;
Response.Write(tn.GetStringValue("DocumentPageDescription", string.Empty));
The DocumentPageTitle and DocumentPageDescription were coming back as null when the custom page type document/page was inheriting from parent/global values.
I was able to use the following to get the properties when not inheriting, while falling back to the parent value when inheriting was taking place:
string documentPageTitle = document.GetStringValue("DocumentPageTitle", DocumentContext.CurrentTitle);
This approach came from the following issue on Kentico DevNet.
Thank you for your help and suggestions, it's appreciated.
I got a requirement. I have added two text fields Value and Key from structure in Web Content Display portlet.
right now in the portlet i am getting value from hard code like below.
BasicModel model = (BasicModel)requestContext.getFlowScope().get("BasicModel");
if(model == null){
model = new BasicModel();
}
model.setEmployeeId("AB1223344S");
model.setHireDate("01-Jan-2000");
model.setNiNumber("AB123456S");
model.setDateOfBirth("12-Dec-1980");
model.setBasicForm(new BasicDetailsForm());
}
but what i want is to get the value of each attribute from web content. Like, If i have given lfr.intel.empid as key and ABSD1822D as value in the added web content structure field like this.
and we can fetch the value of key like this.
model.setEmployeeId(lfr.intel.empid);
You can write a custom function for this which passes the key to that function, now that function will use the JournalArticleLocalServiceUtil API to get respective value from the DB.
Now you need to find How to fetch values from JournalArticleLocalServiceUtil, which you can google or this link can help you.
Thanks.
Try this, assuming that you could get the JournalArticle object, I've done it using the resourcePrimKey
long resourcePrimKey = 12345; //hard coded the resourcePrimKey
JournalArticle article = JournalArticleLocalServiceUtil.getLatestArticle(resourcePrimKey);
com.liferay.portal.kernel.xml.Document document = SAXReaderUtil.read(article.getContentByLocale("en_US"));
Node keyNode = document.selectSingleNode("/root/dynamic-element[#name='Key']/dynamic-content");
String key = keyNode.getStringValue();
Node valueNode = document.selectSingleNode("/root/dynamic-element[#name='Value']/dynamic-content");
String value = valueNode .getStringValue();
I'm using Alfresco 5.0.d
I see in the search json result (with firebug console panel) that in addition to result items , 2 other properties are returned : numberFound and totalRecords. It seems that Alfresco search engine considers numberFound as total items found.
So it display "numberFound results founded" to user.
The problem is that numberFound is not equals to totalRecords.
I see that totalRecords is the correct number of search result (in fact search always return totalRecords number of items).
So i decided to see in the webscript that performs search (alfresco-remote-api-5.0.d.jar\alfresco\templates\webscripts\org\alfresco\slingshot\search\search.lib.js).
We can easly see that the numberFound property comes from this statement
var rs = search.queryResultSet(queryDef);
var numberFound = rs.meta.numberFound ;
About totalRecords property, it comes from the same statement but a little bit different:
var totalRecords = rs.nodes.length
which is the correct value of number of item really found.
So is it an Alfresco api bug?
If no , is it possible that error comes from my query parameters?
Can someone explains me what does mean the numberFound property?
Thank you.
Below is the URL of java file which is getting called when you are executing search.queryResultSet(queryDef) code.
you can refer below method in the java file.It is adding all the things.
https://svn.alfresco.com/repos/alfresco-open-mirror/alfresco/HEAD/root/projects/repository/source/java/org/alfresco/repo/jscript/Search.java
public Scriptable queryResultSet() //This is java method which is getting called.
Below is the code which is written for what you are getting in result.
meta:
{
numberFound: long, // total number found in index, or -1 if not known or not supported by this resultset
facets:
{ // facets are returned for each field as requested in the SearchParameters fieldfacets
field:
{ // each field contains a map of facet to value
facet: value,
},
}
}
I understood how we parse the url parameters in express routes, as in the example
How to get GET (query string) variables in Express.js on Node.js?
But where do the url parameters come from in the first place?
EDIT:
Apparently, I can build such a query with jquery (i.e $.get). I can append params to this query object. It s cool, but still i m trying to understand how we achieve this in the query that renders the page as a whole.
An example : when i choose the oldest tab below, how does SO add ?answertab=oldest to the url so it becomes :
https://stackoverflow.com/questions/30516497/how-do-we-add-url-parameters-ejs-node-express?answertab=oldest#tab-top
The string you're looking at is a serialization of the values of a form, or some other such method of inputing data. To get a sense of this, have a look at jQuery's built in .serialize() method.
You can construct that string manually as well, and that's pretty straight forward as well. The format is just ?var1=data1&var2=data2 etc. If you have a JSON object {"name": "Tim", "age": 22} then you could write a very simple function to serialize this object:
function serializeObject(obj) {
var str = "?";
for(var i = 0; i < Object.keys(obj).length; i++) {
key = Object.keys(obj)[i];
if (i === Object.keys(obj).length - 1)
str += encodeURIComponent(key) + "=" + encodeURIComponent(obj[key]);
else
str += encodeURIComponent(key) + "=" + encodeURIComponent(obj[key]) + "&";
}
return str;
}
Running seralizeObject({"name": "Tim", "age": 22}) will output '?name=Tim&age=22'. This could be used to generate a link or whatnot.
The page author writes them so. This is how they "come in the first place". The authors of an HTML page decide (or are told by website designers) where to take the user when he clicks on a particular anchor element on it. If they want users to GET a page with some query parameters (which their server handles), they simply add query string of their choice to the link's href attribute.
Take a look at the href attribute of the oldest tab you clicked:
<a
class="youarehere"
href="/questions/30516497/how-do-we-add-url-parameters-ejs-node-express?answertab=oldest#tab-top"
title="Answers in the order they were provided"
>
oldest
</a>
When you clicked it, the browser simply took you to path indicated in href attribute /questions/30516497/how-do-we-add-url-parameters-ejs-node-express?answertab=oldest#tab-top relative to the base URL http://stackoverflow.com. So the address bar changed.
stackoverflow.com may have its own system of generating dynamic HTML pages. Their administrators and page authors have configured their server to handle particular query parameters and have put in place their own methods to make sure that links on their pages point to the URL(including query string) they wish.
You need to provide URIs with query strings of your choice (you can build them using url.format and querystring.stringify) to your template system to render. Then make your express routes process them and generate pages depending on their value.
I know that current URI of page I can get by
#{request.requestURI}
it is in EL also available as follows:
String uri = ((HttpServletRequest) externalContext.getRequest()).getRequestURI();
Can i get current page address with query string at JSF page? How can i do this ?
For example for page with address in browser /pages/work/myPage.xhtml?id=43&idLast=21
I want to get String with /pages/work/myPage.xhtml?id=43&idLast=21
You can do it via HttpServletRequest methods HttpServletRequest#getRequestURI() and HttpServletRequest#getQueryString():
In EL that'd be:
#{request.requestURI}#{not empty request.queryString ? '?' : ''}#{request.queryString}"
