[SAPUI5] Add custom header parameter to all oData queries

 , , , , ,

Simply go to your Component.js file and add this line to the init function:

this.getModel().setHeaders({"myCustomParameter": "test"})

In a CAP Backend, you get this parameter from the express req object, which can be accessed via the req.http property:

req.http.req.headers['myCustomParameter']

And here is a nice code snippet, on how to read this header parameter in an ABAP system: https://answers.sap.com/answers/425621/view.html

[SAPUI5] Get data of an Item of a List or Table

 , , , , , , , , , , , ,

All options have in common that you first try to get the binding context from the list/table element via the event. Having the right context, you can either use the getProperty() function to get a specific property, or use the getObject() function to get all data.

onClick: function (oEvent) {
    // Option 1
    oEvent.getParameters().item.getBindingContext().getProperty("ID") 
    // Option 2
    oEvent.getParameters().item.getBindingContext().getObject().ID
    // Option 3
    oEvent.getParameter("item").getBindingContext().getObject().ID 
    // Option 4
    oEvent.getSource().getBindingContext().getObject().ID 
}

Note: When using a List, it’s oEvent.getParameters().listItem instead of oEvent.getParameters().item.

Or you could also use the sPath property from the binding context and directly get the data from the model.

onClick: function (oEvent) {
    // Option 5
    const sPath = oEvent.getSource().getBindingContext().sPath 
    // 5a
    this.getView().getModel().getProperty(sPath).ID 
    // 5b
    this.getView().getModel().getProperty(sPath + "/ID") 
}

https://sapui5.hana.ondemand.com/sdk/#/topic/5338bd1f9afb45fb8b2af957c3530e8f.html

There are two ways to use a filter.

Option 1:

items="{
				path: '/myItems',
				parameters : {
				  $filter : 'itemName eq \'myItemName\'',
				  $orderby : 'createdAt desc'
				},
}">

Option 2:

items="{
				path: '/myItems',
				parameters : {
				  $orderby : 'createdAt desc'
				},
				filters : {                                     
				  path : 'itemName ',
				  operator : 'EQ',
				  value1 : 'myItemName'
