reduce	array/collection		Reduces collection to a value which is the accumulated result of running each element in collection thru iteratee, where each successive invocation is supplied the return value of the previous. If accumulator is not given, the first element of collection is used as the initial value.

 

import reduce from ‘lodash/fp/reduce’

const noCapReduce=reduce.convert({ ‘cap’: false })

const red = noCapReduce((result,value,key)=>{

    ((result[value])||(result[value]=[])).push(key)

return result;

},{})

console.log(red({ jey11: 1, jey23: 3, jey223: 3 }))

Currying and lodash/fp

Briefly, currying is a way of constructing functions that allows partial application of a function’s arguments. What this means is that you can pass all of the arguments a function is expecting and get the result, or pass a subset of those arguments and get a function back that’s waiting for the rest of the arguments.

Argument Order

One thing that’s important to keep in mind when currying is the order of the arguments. Using the approach we’ve described, you obviously want the argument that you’re most likely to replace from one variation to the next to be the last argument passed to the original function.

Thinking ahead about argument order will make it easier to plan for currying, and apply it to your work. And considering the order of your arguments in terms of least to most likely to change is not a bad habit to get into anyway when designing functions.

Here is how the lodash/fp documentation describes itself:

The lodash/fp module promotes a more functional programming (FP) friendly style by exporting an instance of lodash with its methods wrapped to produce immutable auto-curried iteratee-first data-last methods.

Compose yourself

The idea of composing functions (or flow in lodash) is to build a larger function out of many smaller ones. The data goes in one end and flows (ah ha!) through each function until it comes out the other side. Each function in the chain passes its return value to the next.

Let’s see an example using lodash/fp:

const flow = require('lodash/fp/flow');
const escape = require('lodash/fp/escape');
const trim = require('lodash/fp/trim');

const sanitise = flow(escape, trim);

sanitise('    <html>    '); // <html>

You can see that we’ve created a sanitise function from escape and trim and when the HTML string is passed in it flows through these two functions before being returned as expected. Again, we’re just being implicit and declaring what we want to happen, not how.

How does currying help?

lodash/fp functions are auto-curried, so when given fewer arguments than expected they give back a function. This works really well with flow:

const flow = require('lodash/fp/flow');
const get = require('lodash/fp/get');
const isEqual = require('lodash/fp/isEqual');

const data = {
  items: 45
};

const hasAllItems = flow(get('items'), isEqual(45));

hasAllItems(data) // true

Here we’re configuring the get and isEqual functions with the arguments needed to get the result, and now they’re waiting for their final argument which is the data. Thanks to flow we can pass that in at one end and let it pass through each curried function until our expected value comes out at the end.

For composition to work each function should be unary (accept one argument) and return a single value for the next function to consume. It’s fine for the first function to be polyadic (takes multiple arguments) as long it returns a single value.

A note on point-free

You may have noticed that in the last two examples you can’t see any mention of data or itemsapart from when it is passed in as an argument. From the Wikipedia page:

Tacit programming, also called point-free style, is a programming paradigm in which function definitions do not identify the arguments (or “points”) on which they operate. Instead the definitions merely compose other functions, among which are combinators that manipulate the arguments.

user information list

What is User Information List?

As per the Name SharePoint User Information List stores information about a user by having some metadata set up for the user. Some examples are User Picture, Email, DisplayName, LoginName etc. For a complete list of fields, see further down this blogpost under “User Information List Fields”.

When a user get added in User Information List?

When we grant any user permissions to a user, they are added automatically to the hidden User Information list a new item will be created in the User Information List storing some information about the user.

Even though if we grant access to any active directory group the group gets added to the hidden User Information list as well but the user does not get added until they access the site. (As an example, I granted an AD group permissions to my site & only the AD group showed up in the hidden User Information list not the users

It has been changed little bit in SharePoint 2013. As it shows user in list as soon as I give them permission to site regardless of they logon or not

Where the User Information details are used in SharePoint

When a user add/create or edit an item, documents or pages SharePoint will display the Created By or Last modified by details for the users and these all comes from the SharePoint User Information List

URL for User Information List SP 2010 ?

http://siteurl/_catalogs/users/detail.aspx – If you want to see the detail view of only Users in the list.

http://siteurl/_catalogs/users/simple.aspx – The blow URL will show the simple view of only Users in the List
http://siteurl/_catalogs/users/allgroups.aspx – This will provide all the groups without users available in Site.

URL for User Information List SharePoint 2013?

http://siteurl/_catalogs/users/detail.aspx – If you want to see the detail view of only Users in the list.

http://siteurl/_catalogs/users/simple.aspx – The blow URL will show the simple view of only Users in the List
http://siteurl/_catalogs/users/allgroups.aspx – This will provide all the groups without users available in

http://siteurl/_layouts/15/people.aspx?MembershipGroupId=0

http://siteurl/_layouts/people.aspx?MembershipGroupId=0

URL for User Information List SharePoint online, O365

Or

http://siteurl/_layouts/15/people.aspx?MembershipGroupId=0

Note : /_catalogs folder is not mapped as virtual folder in IIS, like /_layouts, /settings.aspx or other application pages that we have in SharePoint site etc, i.e. it will work only on the root site.

Here the important thing is that these endless Users, AllUsers, SiteUsers, etc properties of SPWeb and SPSite, which may return different results depending on the context site, should not mislead you: users are created on site collection level.

User Information List is a special one but still is a list and is bound to the web scope. So it is stored only in the root web of each site collection and you wouldn’t find it in any subweb

In theory this list should be updated with user profile synchronization as well, but at first SharePoint may be used without user profiles, and second because of a lot of bugs in this process, on practice the most reliable way to force synchronization between user profiles and user information list is to delete user from the list explicitly and call SPWeb.EnsureUser(). We had similar situation and it was the only method which really worked (in our case it was more tricky: samAccountName of the user account in AD was changed, but as SID remained the same, Sharepoint still showed old account name).

If there is some users who’s details are showing differently in SharePoint than its AD value

You can try to sync the user profile with user Information List by below given Power shell script.

To fix the issue run the PowerShell as below. abcDomainName\pqrUserLoginId —> abc is the domain and pqr is the user login.

$web=Get-SPWeb …web URL…

$web|Set-SPUser -identity “abcDomainName\pqrUserLoginId” -SyncFromAD

The problem is the UserInformationList is stored in AllUserData table. This is not the UserInfo table. It is absolutely different portion of data. You can see its data by navigating to http:///_catalogs/users/detail.aspx. It is the site (Web scope) level data and the UserInformationList (hidden list) is created for the Root Web of each site collection. While UserInfo stores data of the site collection level. Information in UserInfo table can be different from UserInformationList. So if i get the user from PowerShel I get the right display name.

$web = Get-SPWeb -Identity ‘WebUrl’
$user = $web | Get-SPUser -Identity ‘login’
$user.DisplayName

If I Remove users from User Information List

We can remove a user from the User Information List (UIL) in a site collection from SharePoint 2010 and 2013. SharePoint stores user information in the UIL to extract data when this user is being searched by the people picker, the people picker extracts information from multiple locations:

– The User Information List
– Active Directory

The people picker does not extract information from the User Profile Service Application (UPSA). The UPSA syncs information from the AD and updates the UIL but it does not delete the user from it.

For example if I will delete myself from the Active Directory and navigate back to SharePoint to see what happened.

– I can no longer log on with “myLogInName”
– I can still find “myLogInName” with the people picker.

– The permissions are still visible

I want to delete myLogInName user from the Site Collection so this user won’t be found by the people picker and the permissions will be deleted.

Solution

I can’t just click on the user and delete him because I’ll be redirected to the My Site (the My Site will be scheduled for deletion in 14 days by the My Site Cleanup Timer Job).

You will have to add the following right behind the URL

SharePoint 2010

/_layouts/people.aspx?MembershipGroupId=0

and click on “Actions –> Delete Users from Site Collection

After that

I can now

– no longer log on with “myLogInName”
– no longer find him using the people picker
– no longer find his permissions because they have been deleted

Downside is that you’ll receive the following error while clicking on this user at documents

With the following information from the ULS Viewer

System.ArgumentException: User cannot be found.

at Microsoft.SharePoint.SPList.GetItemById(String strId, Int32 id, String strRootFolder, Boolean cacheRowsetAndId, String strViewFields, Boolean bDatesInUtc)

at Microsoft.SharePoint.SPContext.get_Item()

Deleting users from UIL’s in bulk and across Site Collections

Please read the following blog from Nico Martens if you would like to delete users in bulk with PowerShell.

Timer Job that is working behind the User Information List?

To synchronize the User Profile user Data with user Information List there are two timer jobs that are responsible
1.1. User Profile to SharePoint Quick Sync and
2.2. User Profile to SharePoint Full Sync,

Can I set Alert on SharePoint User information list? Or Can I Track changes to the SharePoint User Information list.

How do you track the changes in “User Information List” without using any custom code? One way is to enable auditing under site collection administration for “Editing users and permissions”. However this add an extra load to the database and may result in performance issues. Moreover his requirement was to track only when a user is added or removed from site collection.

Another approached is to setup alerts. However, the User Information List does not have any option to setup alerts or go to setting etc as normal lists. So how can we configure alerts on the list?

1. Our first requirement was to get the GUID. To get this we queried dbo.Lists table in the content database holding this site collection.

2. The query should be: Select tp_ID From Lists with(NoLock)where tp_Title = ‘User Information List’

3. Make a note of this ID, Now go to any other list in the top site in your site collection and click on Alert Me under Actions.

4. In the next page in URL remove the contents after ?List= and add the GUID noted in step 3.

5. Press enter and now you will find that the fields are populated with User Information List and you can create the alerts.

It is not possible to add event handlers to the user info list ?

No, we cannot attach any event handler to User Information List. Please check the MS details on that on this article (http://msdn.microsoft.com/en-us/library/aa979520.aspx), we know that “Lists:List events do not fire on the UserInfo list.”

Another asynchronous was discussed in this post below: we can think to create a service to monitor the change in UserInfo list, or get the modification logs from audit information is also a solid alternative.

Please see this following thread:

http://social.msdn.microsoft.com/Forums/en-US/sharepointdevelopment/thread/81aae5ef-9621-48c5-ad52-706e5d6a0f05

How user Information list is linked with SharePoint User Profile Service?

To keep all the information in the user information lists up to data with User profile and user Information list is a task that is handled by the Profile Synchronization and the Quick Profile Synchronization timer jobs. By default the first job runs once every hour, the second one runs every couple of minutes and is incremental. The first time user data is replicated from the user profile to the user information list of a site a full update is needed. So the Profile Synchronization job needs to run in order to get the data replicated to the site and this may take up to an hour. If information about a user is already stored in the user information list and the information changes in the user profile it will be synchronized with the data in the site collection by the Quick Profile Synchronization job.

You can also kick off the profile synchronization jobs by running the stsadm sync command.

stsadm -o sync

If you believe that information is not synced between the user profiles and the user information lists in one or more sites you can request a list of content databases that have not been synchronized for x number of days by using the following stsadm sync command.

stsadm -o sync -listolddatabases

If one or more content databases show up in this list you can clean up the sync list so they can be added to the list again.

stsadm -o sync -deleteolddatabases

You can also use the sync command to change the schedule for the synchronization job.

For more information on the stsadm sync command have a look here http://technet.microsoft.com/en-us/library/cc263196.aspx.

To synchronize the User Profile user Data with user Information List there are two timer jobs that are responsible
1.3. User Profile to SharePoint Quick Sync and
2.4. User Profile to SharePoint Full Sync,

That synchronize the User Profile database information with the UIL. Sometimes this stops working (properly) and in that case you need to run:

stsadm -o sync -listolddatabases 0

stsadm -o sync -deleteolddatabases 0

The first command will list Content Databases that haven’t had the UPA -> UIL sync occur in 0 or more days. The second command will delete the records corresponding to those databases (it doesn’t delete databases/end user data).

If still the issue is there you can delete the user from user Information list and run the user profile sync again to fix the issue.

How to access User information list using Server Object model?

// Get the List Object for User Information List
SPList userInformationList = SPContext.Current.Web.SiteUserInfoList;
// Get the Object of current logged in user
SPUser user = SPContext.Current.Web.EnsureUser(@”web”);

// Here is actual User Information is within this SPListItem
SPListItem userItem = userInformationList.Items.GetItemById(user.ID);

The above code will give you the SPListItem object which links to the currently logged in user (the one executing the request) and you have almost all the details about the user you can play around it and user it further.

You can then work with the SPListItem object like normal to get or set the properties like this:

string userPictureURL = userItem[“Picture”].ToString();

How to access User Information list using Client object model?

Here is the example of to get current log in user Id and show user Information by fetching from user Information list.

var contextObj = new SP.ClientContext.get_current();

var webObj = contextObj.get_web();

var userInfoListObj = webObj.get_siteUserInfoList();

var camlQuery = new SP.CamlQuery();

camlQuery.set_viewXml(” +

” + userId + ” +

‘1’);

this.userInfoListObj= userInfoListObj.getItems(camlQuery);

contextObj.load(this.userListItem);

contextObj.executeQueryAsync(

Function.createDelegate(this, onSucceeded),

Function.createDelegate(this, onFailed));

The onSucceeded function is called when the query runs successfully, otherwise the onFailed function will be executed.

function onSuceeded(sender, eventArgs)

{

var item = this.userListItem.itemAt(0);

var name = item.get_item(‘Name’);

var userName = “Name”;

if (name) {

userName = name;

}

alert(userName);

}

We need to execute the code after SP.js is loaded SP.SOD.executeOrDelayUntilScriptLoaded(LoadUserInfo, ‘SP.js’);

How to access User information list for SharePoint online Site?

/_catalogs/users/detail.aspx is work in both Onpremise and SharePoint Online

How to access User Information list using powershell scripts.

You can write a PowerShell script(named ListWebUserInformationListItems.ps1) as following:

# Run with SharePoint 2010 Management Shell

$webUrl = Read-Host “Enter the web url”

$web = Get-SPWeb $webUrl

$list = $web.Lists[“User Information List”]

$query = New-Object Microsoft.SharePoint.SPQuery

$queryCamlString = ”

$query.Query = $queryCamlString

$userInformationListItems = $list.GetItems($query)

foreach($userInformationListItem in $userInformationListItems)

{

echo $userInformationListItem.Title

}

Double negation Javascript

It casts to boolean. The first ! negates it once, converting values like so:

• undefined to true
• null to true
• +0 to true
• -0 to true
• '' to true
• NaN to true
• false to true
• All other expressions to false

Then the other ! negates it again. A concise cast to boolean, exactly equivalent to ToBoolean simply because ! is defined as its negation.
