How to read the content of a file with CommonsMultipartFile in Grails

Question

I can't read the file that I upload in Grails. write is the column in the db where I store the file that I uploaded.

CommonsMultipartFile testFile = request.getFile('templateFile')
InputStream inputStream = testFile.getInputStream()
bookInstance.write = inputStream

What type is the `write` property of `bookInstance`? – Ian Roberts May 29 '15 at 11:11 — Ian Roberts, May 29 '15 at 11:11

There's many ways you can do it. Have a look:

how to upload file into server directory with grails?

Multiple File Upload in Grails

and much more!

If you want the content of the file as a string you can do:

CommonsMultipartFile testFile = request.getFile('templateFile')
InputStream inputStream = testFile.getInputStream()
bookInstance.write = inputStream?.text

Notice the calling of getText() on the stream instance.

Look the error message with your suggestion: No such property: write for class: Possible solutions: dirty – Simpson May 29 '15 at 11:17
Just assign the String to a field you've created on the bookInstance class. – defectus May 29 '15 at 11:25

Probabily you forgot to use a multipart encoded form: <form enctype="multipart/form-data">. In Grails, you can use a <g:uploadForm>. Could you check that in your gsp/html code?
