[CAP] Posting form data to a destination using executeHttpRequest

        const FormData = require('form-data')

        try {
            //Create payload
            const form = new FormData()
            form.append('file', fileContent, {
                contentType: 'application/pdf'
                filename: 'test.pdf'
            })

            //Create headers
            const headers = {
                ...form.getHeaders(),
                'Content-Length': form.getLengthSync(),
            }

            //Send to Destination
            const response = await executeHttpRequest(
                { destinationName: 'TESTINATION' },
                {
                    method: 'POST',
                    url: 'myApiPath',
                    headers: headers,
                    data: form,
                    responseType: 'arraybuffer' // if you need the response data as buffer to prevent UTF-8 encoding
                }
            )
            console.log({response})
        } catch (error) {
            console.error(error.message)

[CAP] Fiori Elements – Add section with PDFViewer

I have a CAP Service that provides a PDF file that I needed to display in a Fiori Elements frontend using the sap.m.PDFViewer. The viewer should be placed in a section on the object page after navigating from the ListReport main page.

My CAP Service has the following annotations to provide the PDF.

  entity pdfFiles : cuid, managed {
    content            : LargeBinary @stream @Core.MediaType: mediaType @Core.ContentDisposition.Filename: fileName @Core.ContentDisposition.Type: 'inline';
    mediaType          : String      @Core.IsMediaType: true;
    fileName           : String      @mandatory;
  }

Add a custom section to your view following this example: https://sapui5.hana.ondemand.com/test-resources/sap/fe/core/fpmExplorer/index.html#/customElements/customSectionContent
Two steps are necessary.

1. Add a new section via the manifest. The template path should match your app namespace.

        "ObjectPage": {
          "type": "Component",
          "id": "ObjectPage",
          "name": "sap.fe.templates.ObjectPage",
          "viewLevel": 1,
          "options": {
            "settings": {
              "editableHeaderContent": false,
              "entitySet": "pdfFiles",
             "content": {
                "body": {
                  "sections" : {
                    "myCustomSection": {
                      "template": "sap.fe.core.fpmExplorer.customSectionContent.CustomSection",
                      "title": "{i18n>pdfSection}",
                      "position": {
                        "placement": "After",
                        "anchor": "StandardSection"
                      }
                    }
                  }
                }
              }
            }
          }
        }

2. Add the section content by defining a new fragment in the file CustomSection.fragment.xml

<core:FragmentDefinition xmlns:core="sap.ui.core" xmlns="sap.m" xmlns:l="sap.ui.layout" xmlns:macro="sap.fe.macros">
	<ScrollContainer
		height="100%"
		width="100%"
		horizontal="true"
		vertical="true">
		<FlexBox direction="Column" renderType="Div" class="sapUiSmallMargin">
			<PDFViewer source="{content}" title="{fileName}" height="1200px">
				<layoutData>
					<FlexItemData growFactor="1" />
				</layoutData>
			</PDFViewer>
		</FlexBox>
	</ScrollContainer>
</core:FragmentDefinition>

On the ObjectPage you will now have a new section containing the PDFViewer.

[CAP] CQL Expand Composition / Deep read

In the documentation they always use a star in string literals like this o => o.`*` to select all fields, but when running this it always failed. However, after some tests I found that this format works with brackets o => o.('*')

https://cap.cloud.sap/docs/guides/providing-services/#–-deep-read

entity myEntity: cuid, managed {
    field1          : String;
    comp            : Composition of one myComposition;
}
 
aspect myComposition: cuid, managed {
    myCompField: String;
}
        const result = await SELECT.from(myEntity)
            .columns(e => {
                e('*')
                e.comp(c => c.myCompField) //expand composition, but only select 'myCompField'
            })

Update 14.09.2023: is now fixed (#)

[CAP] CQL Deep Update

A Composition of one can be updated via the Parent Entity, like we would do it, when dealing with an Association to one.

entity myEntity: cuid, managed {
    field1          : String;
    comp            : Composition of one myComposition;
}

aspect myComposition: cuid, managed {
    myCompField: String;
}
            const { myEntity } = srv.entities
            const EntityComposition = srv.entities['myEntity.myComposition'] // composition

            srv.after('CREATE', EntityComposition , async (comp, req) => {
                await UPDATE(myEntity, comp.ID)
                    .set({
                      comp : [{ myCompField: 'test' }]
                    })
            })

A Composition of many must be updated via the actual Composition Entity.

entity myEntity: cuid, managed {
    field1          : String;
    comp            : Composition to many myComposition;
}

aspect myComposition: cuid, managed {
    myCompField: String;
}
    const EntityComposition = srv.entities['myEntity.myComposition'] // composition

    srv.after('CREATE', EntityComposition , async (comp, req) => {
        await UPDATE(EntityComposition, { up__ID: comp.up__ID, ID: comp.ID }).set({ myCompField: 'test' })
    })

[SAPUI5] Place fields horizontally opposite each other

Because I always forget how to place a field at the beginning of a line and one opposite at the end, I create this post…

The easiest way to do this is using a Flex Box and the property justifyContent like in this sample: https://sapui5.hana.ondemand.com/#/entity/sap.m.FlexBox/sample/sap.m.sample.FlexBoxOpposingAlignment

<FlexBox alignItems="Center" width="100%" justifyContent="SpaceBetween">
    <Text text="Text1" textAlign="Begin"/>
    <Text text="Text2" textAlign="End"/>
</FlexBox>

Another way is a using a Toolbar and a ToolbarSpacer. But of course a Toolbar should only be used, when it makes sense to use a Toolbar.

<Toolbar>
    <Text text="Text1" textAlign="Begin"/>
    <ToolbarSpacer/>
    <Text text="Text2" textAlign="End"/>
</Toolbar>

[CAP] UploadSet http test file

How to create an uploadSet in combination with a CAP backend: https://blogs.sap.com/2021/08/18/my-journey-towards-using-ui5-uploadset-with-cap-backend/

You can test the uploadSet CAP backend part using these http calls:

### Create file
# @name file
POST http://localhost:4004/v2/admin/Files
Authorization: Basic admin:
Content-Type: application/json

{
    "mediaType": "image/png",
    "fileName": "picture.png",
    "size": 1000
}

### Fill Variable from Response
@ID = {{file.response.body.$.d.ID}}

### Upload Binary PNG content
PUT http://localhost:4004/v2/admin/Files({{ID}})/content
Authorization: Basic admin:
Content-Type: image/png

< ./picture.png

### Get uploaded png
GET http://localhost:4004/v2/admin/Files({{ID}})/content
Authorization: Basic admin:

The picture.png file must be in the same folder as the http test file.
