safely crawl all documents via webscript

what i am trying to do is:

find all nodes in the repo and get their file size. also get all versions of the node and calculate the overall filesize of the node and its versions.

how can i safely crawl every document in the repository?

searchservice is going to hit the result-limit easily, even if i increase the limit, the searches wont return results.

by traversing recursively through the repository i also seem to fill up the solr caches

private staticvoid traverse(List<FileInfo> context){for(FileInfo node : context){if(node.isFolder()){
            traverse(fileFolderService.list(node.getNodeRef()));}else{// is file = do stuff}}}

... :44,186  INFO  [solr.component.AsyncBuildSuggestComponent][Suggestor-alfresco-1] Loaded suggester shingleBasedSuggestions, took 267411 ms

i understand it is an antipattern to grab everything at once, but i don't know of any service/api that allows me to page the results into batches/pages,
please enlighten me :(

Clearing/Unsetting the value of a date property via REST API

Hi.

I'm developing a Java application that connects to Alfresco Community 4.2.

One of the functionalities involves setting and modifying a document's properties through /alfresco/service/api/metadata/

I create a JSONObject and set the value of each property, which works perfectly for all cases, except when trying to clear or unset the value of a Date property.

I tried sending "" (empty string) or null as the property's value, but when I check the metadata, the property has the same data as before.

Basically what I'm trying to do is replicate via REST API the behavior of the "None" button in the faces interface: ScreenShot

Is there a way to do that via WebScripts?

Thank you.

Hello people,

Alfresco community edition returns 500 internal error when trying to unshare a file which is in users' private site.

To reproduce:

1.User creates a private site
2.User creates a file
3.User shares it
4.A rest call to unshare this file with admin credentials returns

I think because admin is not a collaborator on the site, he doesn't have a role associated which causes the null pointer exception at UnshareContentDelete.java:96  if(role.equals(SiteModel.SITE_CONSUMER)|| role.equals(SiteModel.SITE_CONTRIBUTOR))

If admin is manually added as a collaborator to the site, the rest call succeeds.

I'm able to download the file with admin credentials, so the admin does have read access and should be able to unshare as per http://docs.alfresco.com/5.0/references/RESTful-QuickshareUnshareDelete.html. This makes me think the issue is at webscripts and not internal API.

Is there any other temporary quick fix for testing (making the admin a site manager, unsharing the file and removing?)

Thanks

importing existing portal webapps

Hi there, I’ve spun up a Alfresco Community 4f so that the business people can do BPM and Doc management

We have an existing portal where we access some small number of webapps (mostly javascript pages that call out to various internal servers for data) — I can’t figure out where/how to add those into Alfresco, all of the integration talk seems to be about accessing Alfresco programmatically from other apps.

These apps would have nothing to do with Alfresco other than appearing as content within an Afresco site -- framed? portlet-ed?

I’ve been paging thru the posted extensions and found a dashclock portlet — is that the direction I need to go or are there others?

Many of the apps are AngularJS -- I hope that's not going to be a barrier to bringing them in.

Thanks

List all site roles of a user

Hello,

I'm trying to list all site roles (or preferably site groups) of a user.

I'm familiar with GET /alfresco/s/api/people/{userName}?groups=true to get the groups the user is a member of, but it doesn't return site groups such as GROUP_site_{sitename}_SiteContributor. Could I somehow modify this request to also get all site groups of the user?

Other request I have tried to use to solve this is GET /alfresco/s/api/people/{userid}/sites?size={pagesize?}&pos={position?}&roles={roles?} which lists sites the user is an explicit member of, but this doesn't return the exact member roles/groups of {userid}. Could I perhaps use the roles-parameter to find this out? I have learned that using roles=user I can get the site roles of the user making the request, but I want to find out the site roles of {userid}.

I can also get the user's role for a site by using GET /alfresco/s/api/sites/{shortname}/memberships/{authorityname}, but using this I would have to loop through all the sites to get the list of all site roles of a user, which doesn't seem a nice solution.

Is there a way to solve this problem?

Thanks

Hi,

I've created a two-field webform and the attachment button to allow a document to be posted to Alfresco Community 5.0.d Repository as per the online tutorial we're all familiar with. It works great.

I have next created a webform with about 12 data fields. I would like to take these 12 pieces of information in the data fields and transfer (parse) them to a document with corresponding blank fields in my Alfresco repository. Not being the most fluent in Java, I’ve been unsuccessful in devising a strategy to do so.

can anyone out there offer some pointers about how I can accomplish this?

Webscript to export nodes to Excel: cannot call getWriter() after getOutputStream()

Hello everybody,

I have created a Spring Surf presentation webscript that queries the Alfresco repository for some list of nodes, and then exports a selection of node properties to an Excel file, to be downloaded by the user.
The Excel is generated on-the-fly, without being saved to the repository, and it is being streamed directly to the browser.

I have used the following XML webscript description:

<webscript>
<shortname>ElasticSearch search and export as Excel</shortname>
<description>ElasticSearch search and export as Excel</description>
<url>/es/exportexcel</url>
<authentication>none</authentication>
<format default=""></format>
</webscript>

and the webscript looks like this:

public class PublicSearchExportExcelWebScript extends AbstractWebScript {@Override
	public void execute(WebScriptRequest req, WebScriptResponse res)throws IOException {
		res.setContentType("application/vnd.ms-excel");
		res.setHeader("Content-Disposition","attachment; filename=\"export.xls\"");
		Workbook wb =new HSSFWorkbook();//..... build Excel
		OutputStream contentOutputStream = res.getOutputStream();
		wb.write(contentOutputStream);}}

But whenever I try to download the Excel file by using this webscript, I get this error in the logs (even if the file is downloaded successfully):

I investigated a bit inside the Spring Surf sources, and I identified that the error occurs at the following lines inside LocalWebScriptRuntimeContainer:

// call through to the parent container to perform the WebScript processing
        ExtensibilityModel extModel = openExtensibilityModel();super.executeScript(scriptReq, scriptRes, auth);
        closeExtensibilityModel(extModel, scriptRes.getWriter());

and then again inside AbstractRuntime when trying to redirect to the error status template:

String validTemplatePath = container.getTemplateProcessorRegistry().findValidTemplatePath(statusTemplate.getPath());
        TemplateProcessor statusProcessor = container.getTemplateProcessorRegistry().getTemplateProcessor(validTemplatePath);
        statusProcessor.process(validTemplatePath, statusModel, res.getWriter());

Is there a way for me to suppress the calling of getWriter after I have generated the binary content and streamed it to the response output stream?

Custom 404 error message if document not found

Web Scripts

Hello,

I want to display a custom error message when file is not found using "View in browser" feature in Alfresco Share.

Example test file:
https://mydomain/share/proxy/alfresco/api/node/content/workspace/SpacesStore/70d263f4-f9e6-498d-93b2-549f64fbaa83/test1.txt

My document test1.txt doesn't exist so Alfresco return an standard error message with all traces. OK.
However, I don't want my users see this page.
I would like to replace this with a custom page or friendly message.

Following these subjects:
http://ecmarchitect.com/alfresco-developer-series-tutorials/webscripts/tutorial/tutorial.html#your-first-web-script
https://forums.alfresco.com/forum/developer-discussions/web-scripts/friendly-error-pages-02192009-1431

I created a plain text file nammed 404.html.ftl in Data Dictionnary/Web Scripts folder, with custom content:

<html><body><p>My custom message.</p></body></html>

Refresh the webscript and put the test file URL, I still get the Alfresco standard error message (cf AlfrescoError404_fileNotFound.png)

Rename 404.html.ftl to 404.ftl, refresh the webscript, and I get the browser error message for 404 error, but not my custom message (cf IEError404_fileNotFound.png).

How can I display my custom message?

Thanks for your help.
