Hello, I need help!!I have this field to upload documents to a databasea!fileUploadField( label: "Document", labelPosition: "ADJACENT", /*maxSelections: 1,*/ value: ri!newDo.docum, saveInto: { ri!newSoli.documentation, ri!newDo.docum, a!save(ri!newDo.day,now()) }, target: cons!C_FLD_document, validations: {} )
What I want to achieve is that when uploading several documents I can do it and it does not appear"Expression evaluation error in rule 'cpro_i_nuevasolicitud' at function a!fileUploadField [line 146]: Error in a!forEach() expression during iteration 1: Expression evaluation error at function fn!content_appian_internal [line 12]: Null Arguments are Invalid"THANKS

Your query is not so clear.
Do you want to store the documents into KC and store their docId into Appian?
Or, are you trying to store the documents directly into the DB? Because file upload fields are not meant for serving this. This allows you store the documents into Appian KC and later you can store the docId's into the Database.
Are you trying to refer to Blob?
I AM TRYING TO UPLOAD VARIOUS FILES AND THAT THESE FILES ARE SAVED IN MY DATABASE
Try this inside button:
this will create a separate row in database for each file attached
saveInto: { a!forEach( items: local!loadedFiles, expression: { a!save(ri!loadedFiles[fv!index].fileAttached, fv!item) }
}
Thanks! But I do not know what to put to replacelocal! loadedFilesfv! index
it would be like this?
a!fileUploadField( label: "Document", labelPosition: "ADJACENT", /*maxSelections: 1,*/ value: ri!newDo.docum, saveInto: { a!forEach( items: ri!newDo.documentation, expression: { a!save(ri!newDo.documentation[fv!index].fileAttached, fv!item) } ), ri!newSoli.documentation, ri!newDo.docum, a!save(ri!newDo.day,now()) }, target: cons!C_FLD_document, validations: {} )
declare a local variable and use it in your fileUploadField control.
code for file upload field:
a!fileUploadField( label: "Document", labelPosition: "ABOVE", target:cons!C_FLD_document, value: local!loadedFiles, saveInto: local!loadedFiles, validations: {} )
put the below code in your button saveInto:
saveInto: {a!forEach(items: local!loadedFiles,expression: { a!save(ri!loadedFiles[fv!index].fileAttached, fv!item)}}
-----------------------------------------------------------------
ri!loadedFiles: is your CDT where you are loading the files.
fileAttached: a column in your CDT
