Posted on by Danilo Costa 20

Hello, I'm creating a Js so that it brings me the Schema name, Type, of an entity on the console.
so far I can do it, what I'm having trouble with is bringing all the DisplayName and field size of all the fields of the selected entity.

Follow current code please help me with this question.
Thanks.

function TesteCa() {

    console.log("INICIO MEU LOG");

    var req = new XMLHttpRequest();
    req.open("GET", Xrm.Page.context.getClientUrl()   "/api/data/v8.2/EntityDefinitions(LogicalName='account')/Attributes?$select=SchemaName", true);
    req.setRequestHeader("OData-MaxVersion", "4.0");
    req.setRequestHeader("OData-Version", "4.0");
    req.setRequestHeader("Accept", "application/json");
    req.setRequestHeader("Content-Type", "application/json; charset=utf-8");
    req.setRequestHeader("Prefer", "odata.include-annotations=\"*\"");
    req.onreadystatechange = function () {
        if (this.readyState === 4) {
            req.onreadystatechange = null;
            if (this.status === 200) {
                debugger;

                var results = JSON.parse(this.response);

                for (var i = 0; i < results.value.length; i  ) {

                    console.log("Schema Name: "   results.value[i].SchemaName   ", Type: "   results.value[i]["@odata.type"]);

                    //document.getElementById("Schema Name: "   results.value[i].SchemaName   ", Type: "   results.value[i]["@odata.type"]).innerHTML = results;
                }
            } else {
                Xrm.Utility.alertDialog(this.statusText);
            }
        }
    };
    req.send();


}

he returns me
Schema Name: TerritoryIdName,
Type: # Microsoft.Dynamics.CRM.StringAttributeMetadata

I need to add it
DisplayName
Size

Thanks

    RE: get all entity metadata display names via javascript?

    so that I can get all the entities

    and when to choose the entity dynamically

    lists this data for each entity

    Example

         | ENTITY NAME: account DISPLAYED NAME: Address 1: UPS zone | SCHEME NAME: Address1_UPSZone | TYPE: String | SIZE: 8 |

    o (| ENTITY NAME: account) I will define it in a drop-down list for the user to choose the entity, and so choose to list the fields with the data above.

    can I do this by taking all the values of (/api/data/v8.2/EntityDefinitions)?

    How could you pass the entity dynamically and select

    Example /api/data/v8.2/EntityDefinitions(LogicalName='account ')

    and return

    DISPLAY NAME: Address; SCHEME NAME: Address1_UPSZone; TYPE: String; SIZE: 8

    And with your help I managed to return those above.

    Now I need a solution to be a dynamic choice.

    in Javascript or Webresource

    Thank you in advance.

    Hi Danilo,

    Try using $expand=Attributes for your query.

    https://docs.microsoft.com/en-us/powerapps/developer/data-platform/webapi/query-metadata-web-api#querying-entitymetadata-attributes

    I have modified you code, but not sure what does the  your "Size" refer to, so I list all string type fields and their DatabaseLength property.

    (It seems that for other types of fields besides String, they don't have property which is similar to size.)

    Please let me know whether the code would work for you.

    console.log("INICIO MEU LOG");

    var req = new XMLHttpRequest();
    req.open("GET", Xrm.Page.context.getClientUrl()   "/api/data/v8.2/EntityDefinitions(LogicalName='account')?$select=LogicalName&$expand=Attributes", true);
    req.setRequestHeader("OData-MaxVersion", "4.0");
    req.setRequestHeader("OData-Version", "4.0");
    req.setRequestHeader("Accept", "application/json");
    req.setRequestHeader("Content-Type", "application/json; charset=utf-8");
    req.setRequestHeader("Prefer", "odata.include-annotations=\"*\"");
    req.onreadystatechange = function () {
        if (this.readyState === 4) {
            req.onreadystatechange = null;
            if (this.status === 200) {

                var results = JSON.parse(this.response);

                for (var i = 0; i < results.Attributes.length; i  ) {

                    if (results.Attributes[i].AttributeType === 'String') {
                        if (results.Attributes[i].DisplayName.LocalizedLabels.length > 0) {
                            console.log("Display Name: "   results.Attributes[i].DisplayName.LocalizedLabels[0].Label   ", Size: "   results.Attributes[i].DatabaseLength);
                        }
                    }

                }
                
            } else {
                Xrm.Utility.alertDialog(this.statusText);
            }
        }
    };
    req.send();
