[web2py] why Web2py doesn't compile all
I'm using web2py in python3.6. When running the app on the local machine, everything is fine. But when I compile and run it again, I get errors that a module does not exist. The module is not found in the compiled folder. How do I solve this??

An upload field will store the original filename and an obfuscated filename
(that is, a new name for the file that contains a unique portion and an
encoding of the original name). The obfuscated filename, which looks
rather like a hash, is the filename used by the filesystem. The
user/download function in the controllers/default.py understands how to
handle this. The URL to download an uploaded file is generated by
A(" click to download", _href= URL("download", args=row.fdata)
and looks like
download/uploadf.fdata.81a339e105991c67.454e482d3570317670303956505530653369757a394d73484a64465f70657270657475616c5f5352562d48565f323031393038303631373237.txt
Translating this to display an image, here's a controller function:
def testimg():
row = db(db.uploadf.fname=="test1").select().first()
return dict(img = row.fdata)
using the model
db.define_table('uploadf',
Field('fname', 'string'),
Field('fdata', 'upload'),migrate='uploadf.table')
and the view testimg.html looks like
{{extend 'layout.html'}}
{{block header}}
Blah!
{{end}}
{{=IMG(_src=URL("download", img), _alt="test image")}}
After the page is loaded, if you use the browser tools to Inspect Element,
you're shown
To connect with your auth_user table, you may want to add an extra field
that references the file uploaded image.

and

for the Portuguese (Spanish is "41" instead of "31" or "29").
Good luck!

row.file probably doesn't exist, because it would have to be row.keys()
(it's not in the attributes, as you've shown), and then looking in a
putative row.files for row key or attribute doesn't seem sensible.
I don't have any experience with BLOBs, but I believe default/user/download
is able to handle them.
For a file-based upload field, the upload field is a string that
default/user/download uses to locate the file. That is, it is the
obfuscated file name, and the rest of the path is defined by the
uploadfolder value (default, myapp/uploads), as well as uploadseparate and
uploadfs. For BLOBs, you've instead set uploadfield to true. In my case,
the file-base one, the attributes are those of a string, but I don't have
to do much with it except return it in hrefs.
default/users/download will use the path name or the blob field to figure
out what to stream. There are times when it is desirable to set up the
streaming in your code, and I thought this was one of those times, but
Ramos and Val K have pointed out how to use the out-of-the-box tool to do
this.
