I am trying to write my own $.jstree.defaults.unique.duplicate function and replace it.
I tried doing so in the following jsFiddle (line: 68):
$.jstree.defaults.unique.duplicate = function(name, counter){
return name + "_test";
};
Steps to test:
Select Devices
Create Node called Node1
Create Another node under Devices called Node1
It will use the jstree default method to replace it with the default node name vs what my function provides
http://jsfiddle.net/2mbq86at/
Am I doing something wrong? Thanks in advance.
In your code you specify text to use in course of creating a new node.
Take out the pre-defined text and things will start to work as desired for your function $.jstree.defaults.unique.duplicate !
self.createFileNode = function (data) {
//Below code only allows files to be created within folders.
//Structure it as per createFolder method to create files at root
var data = {
//'id': 'tempId',
//'text': 'iOS 8'
}
....
In that case of course a new node's text will be the default 'New node'.
The best is to set a unique node name right upfront on creating a new node, like "text" : "OS_" + (new Date).getTime().
Still for the case of renaming nodes and duplicates: using the unique plugin, on renaming and choosing a duplicate text the node's text will fall back to the original one. If that is not what is desired, things get more complicated as the rename_node.jstree event will not be fired in that case.

I am writing a Golang application using Dgraph for persisting objects. From the documentation, I can infer that a new UID and hence a new node is created everytime I mutate an object/run the code.
Is there a way to update the same node data instead for creating a new node?
I tried changing the UID to use "_:name" for the UID field but even this creates a new node everytime the application is run. I wish to be able to update the existing node if it is already present in the DB instead of creating a new node for it.
Unfortunately the docs aren't very beginner friendly yet :/
To modify / mutate existing data you have to run a set operation and supply a rdf-triple like <uid> <predicate> "value" / <objectYouWantToModify> <attributeYouWantToModify> "quotedStringValue". If it is not an attribute but an edge, the value has to be another <uid>.
The full mutation would be for example
{
set {
<0x2> <name> "modified-name" .
}
}
The . terminates the sequence and there is an optional fourth parameter you can use to also assign a label.
Check https://www.w3.org/TR/n-quads/ for further details.
I want to clone an object obtained from the db context using EF. Such object contains a collection that in turn contains another one.
For the copy or clone of the object, I have a method that creates a new instance, copies all the fields and finally marks the original one as EntityState.Unchaged.
Availability newAvailability = new Availability();
newAvailability = availabilityRepository.Copy(sourceAvailability, user);
newAvailability.RemoveTag(img, tagToRemove);
In the example, I have an availability which contains a set of images where each of them can have tags. What I want to do is to create a clone of the Availability object along with the images, then associate the tags to each image by using a join table.
In a next step, I want to remove a tag from one of the copied images, from the copied Availability.
The result is that the tag is being removed on both arrays.
What is weird, is that RemoveTag extension method doesn't use EF at all. It looks like this:
var filterExpression = new Func<Image, bool>(y => y.Url == img.Url));
var image = availability.Images.FirstOrDefault(filterExpression);
image.Tags.Remove(tag);
return availability;
Now, if I have an Availability like this (assume this the result of joining tables, an availability can have many images and an image can have many tags):
A = 1 ; Image = 1; Tag = 6
and then when I create its copy it looks like:
A = 2 ; Image = 2; Tag = 6
the result should be that the Tag 6 in Image 2 from the Availability gets removed and the source Availability is kept unchanged. But that's not what is happening.
Note: the Copy method is doing at some point
this.context.Entry(availability).State = EntityState.Unchanged;
What could I be doing wrong? How should I avoid EF from removing this child object from the source parent?
Thanks in advance
EDIT:
Found the solution, although I'm not entirely sure what changes internally on doing this. I wrote
imgCopy.Tags = img.Tags;
but when I changed to
img.Tags.ToList().ForEach((_) =>
{
imgCopy.Tags.Add(_);
});
the problem was solved.
I have created an AEM Dialog which prompts the user for a set of links and labels.
These links and labels are stored in a jcr node and are used to generate a menu.
To avoid having to create a custom xtype, I am using the acs-commons multifieldpanel solution, which enables me to nest children under the fieldConfig node.
This works great with only 1 Label/Link pair, but when I add a second one - the property cannot be fetched anymore, since instead of a String, it returns the String hashcode.
The property generated by the multifieldpanel in the jcr node is of type String and is filled correctly when inspecting in CRXDE. The problem occurs when I try to fetch the value from within a Sightly HTML file.
Code
Dialog:
Definitions.js:
"use strict";
use(function () {
var CONST = {
PROP_URLS: "definitions",
};
var json = granite.resource.properties[CONST.PROP_URLS];
log.error(json);
return {
urls: json
};
});
Log output
1 element in multifieldpanel
jcr node variable content
definitions: {"listText": "facebook", "listPath": "/content/en"}
log output
{"linkText":"facebook","linkPath":"/content/en"}
Multiple elements in multifieldpanel
jcr node variable content
definitions: {"listText": "facebook", "listPath": "/content/en"},{"listText": "google", "listPath": "/content/en"}
log output
[Ljava.lang.String;#7b086b97
Conclusion
Once the multifieldpanel has multiple components and stores it, when accessing the property the node returns the String hashcode instead of the value of the property.
A colleague has pointed out that I should use the MultiFieldPanelFunctions class to access the properties, but we are using HTML+Sightly+js and are trying to avoid .jsp files at all cost. In JavaScript, this function is not available. Does anyone have any idea how to solve this issue?
That is because, when there is a single item in the multifield, it returns a String, where as it returns a String[] when there is more than a single item configured.
Use the following syntax to read the property as a String array always.
var json = granite.resource.properties[CONST.PROP_URLS] || [];
Additionally, you can also use TypeHints to make sure your dialog saves the value as String[] always, be it single item or multiple items that is configured.
Don't forget that the use() in JS is compiled into Java Byte code and if you are reading Java "primitives", make sure you convert them to JS types. It's part of the Rhino subtleties.
On another note, I tend to not use the granite.* because they are not documented no where, I use the Sightly global objects instead https://docs.adobe.com/content/docs/en/aem/6-0/develop/sightly/global-objects.html
To access properties, I use properties.get("key")
Hope this help.
I realize that this is a pretty specific question but I would imagine someone has run into this before. So I've got about fifty pages or so that were created about a year ago. We're trying to revamp the page with new components specifically in the header and the footer. Except the content in the main-content area will stay the same. So I'm trying to move over everything from the old pages to the new pages but just keep the main-content area. The problem is I can't just change the resource type on the old page to point to the new page components because the content is different and I'll have a bunch of nodes in the header and footer that I don't want. For example here is my current content structure:
Old Content
star-trek
jcr:content
header
nav
social
chat
main-content
column-one
column-two
footer
sign-up
mega-menu
New Content
star-wars
jcr:content
masthead
mega-menu
main-content
column-one
column-two
bottom-footer
left-links
right-links
Does anybody have any ideas on how to move just the content in the main-content node and somehow remove the other nodes. I'm trying to somehow do this programmatically cause I don't want to create 50 pages from scratch. Any help is appreciated!
You can use the JCR API to move things around at will, I would
Block users from accessing the content in question. Can be done with temporary ACLs, or by closing access on the front-end if you can.
Run a script or servlet that changes the content using JCR APIs
Check the results
Let users access the content again
For the content modification script I suggest a script that modifies a single page (i.e. you call it with an HTTP request that ends in /content/star-trek.modify.txt) so that you can run it either on a single page, for testing, or on a group of pages once it's good.
The script starts form the current node, recurses into it to find nodes that it knowns how to modify (based on their sling:resourceType), modifies them and reports what it did in the logs or on its output.
To modify nodes the script uses the JCR Node APIs to move things around (and maybe Worskpace.move).
It is indeed possible to write a code which does what you need :
package com.test;
import java.io.File;
import java.io.IOException;
import javax.jcr.ItemExistsException;
import javax.jcr.Repository;
import javax.jcr.RepositoryException;
import javax.jcr.Session;
import javax.jcr.SimpleCredentials;
import javax.jcr.Node;
import org.apache.jackrabbit.commons.JcrUtils;
import org.apache.jackrabbit.core.TransientRepository;
import org.xml.sax.SAXException;
public class test {
public void test(Document doc) throws RepositoryException {
try {
// Create a connection to the CQ repository running on local host
Repository repository = JcrUtils
.getRepository("http://localhost:4502/crx/server");
System.out.println("rep is created");
// Create a Session
javax.jcr.Session session = repository.login(new SimpleCredentials(
"admin", "admin".toCharArray()));
System.out.println("session is created");
String starTrekNodePath = "/content/path/";
String starWarsNodePath = "/content/anotherPath"
Node starTrekpageJcrNode = null;
Node starWarstext = null;
setProperty(java.lang.String name, Node value)
boolean starTrekNodeFlag = session.nodeExists(starTrekNodePath);
boolean starWarsNodeFlag = session.nodeExists(starWarsNodePath);
if (starTrekNodeFlag && starWarsNodeFlag) {
System.out.println("to infinity and beyond");
Node starTrekNode = session.getNode(starTrekNodePath);
Node starWarsNodeFlag = session.getNode(starWarsNodePath);
//apply nested looping logic here; to loop through all pages under this node
//assumption is that you have similar page titles or something
//on these lines to determine target and destination nodes
//2nd assumption is that destination pages exist with the component structures in q
//once we have the target nodes, the following segment should be all you need
Node starTrekChildNode = iterator.next();//assuming you use some form of iterator for looping logic
Node starWarsChildNode = iterator1.next();//assuming you use some form of iterator for looping logic
//next we get the jcr:content node of the target and child nodes
Node starTrekChildJcrNode = starTrekChildNode.getNode("jcr:content");
Node starWarsChildJcrNode = starWarsChildNode.getNode("jcr:content");
// now we fetch the main-component nodes.
Node starTrekChildMCNode = starTrekChildJcrNode.getNode("main-content");
Node starWarsChildMCNode = starWarsChildJcrNode.getNode("main-content");
//now we fetch each component node
Node starTrekChildC1Node = starTrekChildMCNode.getNode("column-one");
Node starTrekChildC2Node = starTrekChildMCNode.getNode("column-two");
Node starWarsChildC1Node = starWarsChildMCNode.getNode("column-one");
Node starWarsChildC2Node = starWarsChildMCNode.getNode("column-two");
// fetch the properties for each node of column-one and column-two from target
String prop1;
String prop2;
PropertyIterator iterator = starTrekChildC1Node.getProperties(propName);
while (iterator.hasNext()) {
Property prop = iterator.nextProperty();
prop1 = prop.getString();
}
PropertyIterator iterator = starTrekChildC2Node.getProperties(propName);
while (iterator.hasNext()) {
Property prop = iterator.nextProperty();
prop2 = prop.getString();
}
// and now we set the values
starWarsChildC1Node.setProperty("property-name",prop1);
starWarsChildC2Node.setProperty("property-name",prop2);
//end loops as appropriate
}
Hopefully this should set you on the right track. You'd have to figure out how you want to identify destination and target pages, based on your folder structure in /content, but the essential logic should be the same
The problem with the results I'm seeing here is that you are writing servlets that execute JCR operations to move things around. While technically that works, it's not really a scalable or reusable way to do this. You have to write some very specific code, deploy it, execute it, then delete it (or it lives out there forever). It's kind of impractical and not totally RESTful.
Here are two better options:
One of my colleagues wrote the CQ Groovy Console, which gives you the ability to use Groovy to script changes to the repository. We frequently use it for content transformations, like you've described. The advantage to using Groovy is that it's script (not compiled/deployed code). You still have access to the JCR API if you need it, but the console has a bunch of helper methods to make things even easier. I highly recommend this approach.
https://github.com/Citytechinc/cq-groovy-console
The other approach is to use the Bulk Editor tool in AEM. You can export a TSV of content, make changes, then reimport. You'll have to turn the import feature on using an administrative function, but I've used this with some success. Beware, it's a bit buggy though, with array value properties.
First of all I am using Play framework with scala.
I am creating a graph and with the node id I would like to show some information at the same page.
In order to do that, first I need to get node.name but for some reasons #node.name function is not working. When searching for it I learnt that it's because play is server-side and js is client-side. However I need to get the data somehow.
I also cannot access:
var html = "<h4>" + node.name + "</h4><b> connections:</b><ul><li>"
How can I access this through the view?
My second question is after reaching the js node.name, I need to access to controller and do the same action one more time but this time with the new node.name .
View Part:
onClick: function(node) {
#node.name
}
1) Is this code in your controller? And are the node variable in scope? If so this should be perfectly legal code, since it will be evaluated as pure scala.
2) The templates are a different story however. You probably know they parse everything as normal html, unless escaped. To use a variable you have to bring it into scope by either:
defining a 'constructor' for the template at the absolute beginning of the file:
#(node : Node)
...
#node.name // later in the file
See http://www.playframework.com/documentation/2.0/ScalaTemplates
or define a variable inside the template:
#defining( Get.node.from.somewhere ) { node =>
#node.name
}
See Play! framework: define a variable in template?
If you did either of the two, you should have no problem accessing the node variable. Even in scripts. But note that external scripts does not have access to the same variables. It is thus very common to use inline scripts or import it as another template if you need to access a variable from JavaScript.
Edit: I've made a gist of a template, controller and routes file: https://gist.github.com/Jegp/5732033
