3) Create a Github tab like this:


4) Create Apex Classes and paste the below code on your developer console.

GitHubProvider.cls :-

global with sharing class GitHubProvider extends DataSource.Provider{
    override global List<DataSource.Capability> getCapabilities() {
        List<DataSource.Capability> capabilities = new List<DataSource.Capability>();
        capabilities.add(DataSource.Capability.ROW_QUERY);
        return capabilities;
    }
   
    override global List<DataSource.AuthenticationCapability> getAuthenticationCapabilities() {
        List<DataSource.AuthenticationCapability> capabilities =
                            new List<DataSource.AuthenticationCapability>();
        capabilities.add(DataSource.AuthenticationCapability.ANONYMOUS);
        return capabilities;
    }
   
    override global DataSource.Connection getConnection(DataSource.ConnectionParams connectionsParams) {
        return new GitHubConnection();
    }
}

GitHubConnection.cls :-

global with sharing class GitHubConnection extends DataSource.Connection{
    override global List<DataSource.Table> sync() {
        List<DataSource.Column> gitHubRepoColumns = new List<DataSource.Column>();
        gitHubRepoColumns.add(DataSource.Column.text('ExternalId', 255));
        gitHubRepoColumns.add(DataSource.Column.url('DisplayUrl'));
        gitHubRepoColumns.add(DataSource.Column.text('Name', 128));
        gitHubRepoColumns.add(DataSource.Column.text('Description', 1024));
        gitHubRepoColumns.add(DataSource.Column.number('Stars', 16, 0));
       
        List<DataSource.Table> tables = new List<DataSource.Table>();
        tables.add(DataSource.Table.get('GitHub Repos', 'Name', gitHubRepoColumns));
        return tables;
    }
   
    override global DataSource.TableResult query(DataSource.QueryContext queryContext) {
        List<Map<String, Object>> repos =
            DataSource.QueryUtils.process(queryContext, getOrgRepos('<USERNAME>'));
        DataSource.TableResult tableResult = DataSource.TableResult.get(queryContext, repos);
        return tableResult;
    }
   
    override global List<DataSource.TableResult> search(DataSource.SearchContext searchContext) {
        return DataSource.SearchUtils.searchByName(searchContext, this);
    }
   
    public List<Map<String, Object>> getOrgRepos(String org) {
        Http httpProtocol = new Http();
        HttpRequest request = new HttpRequest();
        String url = 'https://api.github.com/orgs/' + org + '/repos?per_page=1000';
        request.setEndPoint(url);
        request.setMethod('GET');
        HttpResponse response = httpProtocol.send(request);
       
        List<Map<String, Object>> repos = new List<Map<String, Object>>();
       
        for (Object item : (List<Object>)JSON.deserializeUntyped(response.getBody())) {
            Map<String, Object> repo = (Map<String, Object>)item;
            repo.put('ExternalId', repo.get('id'));
            repo.put('DisplayUrl', repo.get('html_url'));
            repo.put('Name', repo.get('name'));
            repo.put('Description', repo.get('description'));
            repo.put('Stars', repo.get('stargazers_count'));
            repos.add(repo);
        }
       
        return repos;
    }
}

5) Go to App launcher and search for GitHub Repos.
It will automatically brings all the files which are in the query.
6) To Create new Branch from the Parent/Main branch. You have to just call the Api.

postGitHub.cls :-

public with sharing class postGitHub {
    public static String postGit(){
        try {
            String json = '{ "ref": "refs/heads/Username", "sha": "SHA" }'; // you have to put your head.
            Http http = new Http();
            HttpRequest request = new HttpRequest();
           //you have to put the endpoint of your repository.            
            request.setEndPoint('https://api.github.com/repos/<USERNAME>/<REPO>/git/refs');
            request.setMethod('POST');
            request.setHeader('Authorization',"Token " + 'YOUR_TOKEN_HERE');
            //
            request.setBody(json);
            HttpResponse response = new HttpResponse();
            response = http.send(request);
            System.debug(response.getStatusCode());
            System.debug(response);

        } catch (Exception e) {
            System.debug(e.getMessage());
        }
        return 'success';

    }
}

After that you can check a new branch is created into your github portal.

Sharing records by Apex in Salesforce

  Greetings, everyone! In today's session, we'll delve into the topic of sharing records within an Apex class. As we're aware, there exist various methods through which we can accomplish the sharing of records. We engage in record sharing primarily when the object's Organization Wide Default (OWD) settings are set to private. Sharing settings come into play when certain predefined criteria are met, allowing us to extend access to records to designated groups or roles. In cases where intricate logic is involved, manual sharing is employed. While this approach proves beneficial for specific records, instances where a multitude of records require automated handling, Apex sharing becomes the preferred solution. Salesforce offers a 'Share' object for each type of object, with distinct naming conventions: For standard objects, it's 'StandardobjectName+Share', such as 'AccountShare' for the 'Account' object. Custom objects follow the pattern...

SF Fact #03 | Undelete Failed, Entity is not in recycle bin

  Similar to ENTITY_IS_DELETED error, if we attempt to undelete a record from recycle bin by mistake which has already been hard deleted, the following error is encountered: UNDELETE_FAILED. When a record is deleted, it moves to the Recycle Bin. This is known as "soft deletion," allowing the record to be easily restored through the user interface. However, under certain conditions, a deleted record will no longer appear in the Recycle Bin: Master-Detail Relationship (Child Deleted First): If a record is a child or detail in a master-detail relationship and it is deleted before its parent record, then after the parent is deleted, the child record transitions to a "hard deleted" status. In this state, the child record cannot be recovered through the Recycle Bin and must be recreated if needed. Master-Detail Relationship (Parent Deleted): If a record is a child or detail in a master-detail relationship and the parent record is deleted, the child record is also soft del...
