Get the visual view of the model in Entity Framework Code First

Introduction

In this post we will discuss how to generate visual view from the models in Entity Framework Code First.

I’m using Visual Studio  2017 as the tool and Entity Framework version 6.

Solution Structure

I have two projects in the solutions.

1. BlogSample.BO
   In this project we will have all the Business Objects.
2. BlogSample.DAL
   This is  the data access layer and we have installed Entity Framework 6 and created DbContex and the Dataset. Also the BlogSample.BO project has been referenced as well.

Step 1

Install Entity Framework 6 Power Tools Community Edition

In Visual Studio go to Tools –> Extensions and Updates.

Search for Entity Framework 6 Power Tools and install the extension.

See the image below. I have already installed.

Step 2

Make DAL project as Startup project. Right click on the Context.cs file and go to Entity Framework –> View Entity Data Model.

Your .edmx visual diagram will be generated as below. 

Solution

The solution is available in the below url.

WebHooks in SharePoint Online – Post 1 – Introduction

“WebHooks in SharePoint Online” will be a series of blog posts.

1. WebHooks in SharePoint Online – Post 1 – Introduction

This is the first post of the series and this post will be on introduction to SharePoint Online WebHooks.

Introduction to WebHooks

WebHooks are HTTP services where the subscribers will notified of events happening. Not only Office 365 or SharePoint uses WebHooks, but it’s a universal model used by Facebook, GitHub, MailChimp etc.

Introduction to WebHooks in SharePoint Online / SharePoint Online WebHooks

WebHooks in SharePoint Online are used for Document Libraries or lists. WebHooks in SharePoint Online are asynchronous event supported, which means that the notification is pushed to subscribers when items are added, updated, deleted or moved. WebHooks in SharePoint Online are not synchronous (“-ing”) event supported. Microsoft recommends Remote Event Receivers for synchronous events.

Why WebHooks over Remote Event Receivers

• WebHooks are easier to consume by “non-SharePoint” developers

Advantages of SharePoint Online WebHooks

• Easy to subscribe and push notification
• Automatic retry is available on failure up to 5 minutes
• Deleted event is available
• Universal model
• Can be used in modern SharePoint development stack such as SharePoint Framework

Disadvantages of SharePoint Online WebHooks

• The subscription period will be expired automatically in 6 months and the subscribers have to re subscribe.
• You cannot use webhooks to cancel an operation.
• SharePoint Online lists and libraries are available.
• No synchronous method is supported.
• Acknowledgement must be received quickly within 5 seconds.
• Subscription and notification uses the same url. The developers should implement their own logics to differ the calls.

Keep in mind when you develop solutions using WebHooks

• WebHooks are only for asynchronous calls
• Send the acknowledgement within 5 seconds
• Implement a way to update the subscription if it is about to expire.

Access SharePoint group users from SharePoint Hosted Add-in through Rest API

Introduction

I was using SharePoint rest api in order to read the users from a SharePoint group.

  

   var url = _spPageContextInfo.webAbsoluteUrl + "/_api/web/sitegroups/getbyname('" + groupName + "')/users";

We can use the Add-in web url since the groups are inherited from the parent site (Host web) to the add-in web.

Problem

When a user (other than the site collection administrator) try to access the above rest url, it throws access denied exception.

Solution

Step 1

Go to “People and groups” under Site Setting.

Step 2

Select the group and then go to “Group Setting” under Setting.

Step 3

Then select “Everyone” radio button for the "Who can view the membership of the group?" option.

Step 4

Click OK

Conclusion

Now other users also will have  the permission to read the users in the group.

Add an Attachment to a list item with PnP JS Core library and Dropzone.js

Introduction

I was using ng-dropzone which is a AngularJS directive for dropzone.js and PnP JavaScript Core Library in order to add an attachment for list item.

I was following this url in order setup dropzone.js in my SharePoint hosted add-in.

In order to add an attachment to SharePoint list item please do the below changes.

1. Replace $scope.dzCallbacks as below
   

  
      $scope.dzCallbacks = {
            'addedfile': function (file) {
                console.log(file);
                $scope.dropZoneFiles.push(file);
            },
            'success': function (file, xhr) {
                console.log(file, xhr);
            },
        };

2. Add below function to insert item and add attachment

Since my solution is a SharePoint hosted add-in I’m using crossDomain call and you have to replace your addinWeb and hostWeb url and also your have to change the list name. My list name is “abc”

  
     $scope.saveItem = function () {
          
            $pnp.sp.crossDomainWeb(addinWeb, hostWeb).lists.getByTitle("abc").items.add({
                Title: "Title",

            }).then((result) => {
              
                $scope.dropZoneFiles.forEach(function (file) {
                    var toUpload = file; 
                    
                    var r = new FileReader();

                    r.onloadend = function (e) {
                        var data = e.target.result;


                        item.attachmentFiles.add(toUpload.name, data).then(function () {
                            alert()
                        });
                    }

                    r.readAsArrayBuffer(toUpload);
                    
                    console.log(result);
                });
            }

Conclusion

The item will be created and the attachment will be uploaded.
