Hi
I want to upload a file via ajax. What I have working for when the file is
stored in a folder, the problem and when I want it stored in a blob field.
*In upload_picture function I do not know how to put the value of
image_blob *
The code is as follows
==================================================================================
/models/db.py
==================================================================================
tb_pictures = db.define_table('pictures',
Field('name'),
Field('image', 'upload', uploadfield='image_blob'),
Field('image_blob', 'blob', writable=False, readable=False),
)
==================================================================================
/controllers/default.py
==================================================================================
def pictures():
return dict(f=LOAD('default', 'formpictures.load', ajax=True, ajax_trap=
True))
def formpictures():
form = SQLFORM(tb_pictures, _id="formuploadajax")
return dict(form=form)
def upload_picture():
fd=request.vars.image
tb_pictures.insert(
name=request.vars.name,
image=fd,
*image_blob=fd,* #<===================
)
#return
==================================================================================
/views/default/formpictures.load
==================================================================================
<script>
$(function(){
$("#formuploadajax").on("submit", function(e){
e.preventDefault();
var f = $(this);
var formData = new FormData(document.getElementById(
"formuploadajax"));
$.ajax({
url: "{{=URL('upload_picture')}}",
type: "post",
//dataType: "html",
dataType: "script",
data: formData,
cache: false,
contentType: false,
processData: false,
success: function (result) {
alert(result);
}
})
});
});
</script>
{{=form}}
