Upload/Download files

To upload files into your Turnkey application you should add an attribute with type of Blob to your class in the model.

You can set it in the attribute properties area in MDriven Designer.

Set the attribute's type and BlobType in attribute proeprties.

MDriven Turnkey will render Blob as the upload button component. Text inside the button depends on your ViewColumn name. Don't forget to use <MyColumn>_FileName and <MyColumn>_ContentType to save your name and content type of the uploaded file (Turnkey will use this information to download file correctly).

To upload images into your Turnkey application you should create an attribute with type of Blob and choose BlobType – "Image" in the properties of the attribute.

In this case MDriven Turnkey will render it as the default image upload component.
