Hi,
I have one form , in which I am using file_field teg for input image
file as follows.
====<%= file_field("store", "picture") %>
======Tha Actual fileld name of my Image field in Database is
"store_photo"
with datatype LargeBLOB.
& Inside my Store Model I have specified "def picture" as
follows:-
========================def picture=(picture_field)
self.store_photo = picture_field.read
end
========================
Now When I am trying to Uplaod file by submitting form I am getting
error like:-
=====================================undefined method `read'' for
"logo.gif":String
=====================================Why I am getting this error? PLease tell me
how to upload file into my
database from a form & also if later I want to retrieve that image from
database & display it on page how to do it?
Thanx.
Prash

It looks like what you think is the object is actually just the filename. Perhaps file_field documentation can help you diagnose this problem. You might also consider whether any changes need to be made to the form itself to facilitate a multiple part submission, file data and params. A. -- Posted via http://www.ruby-forum.com/.
Take a look at file_column Should do what you want http://wiki.rubyonrails.org/rails/pages/File+Column+Plugin On 4/5/06, Prashant Tiwari <tiwari_p_k@yahoo.com> wrote:> > Hi, > > I have one form , in which I am using file_field teg for input image > file as follows. > ====> <%= file_field("store", "picture") %> > ======> Tha Actual fileld name of my Image field in Database is "store_photo" > with datatype LargeBLOB. > & Inside my Store Model I have specified "def picture" as follows:- > ========================> def picture=(picture_field) > self.store_photo = picture_field.read > end > ========================> > Now When I am trying to Uplaod file by submitting form I am getting > error like:- > =====================================> undefined method `read'' for "logo.gif":String > =====================================> Why I am getting this error?

This is exactly why the "Help Vampire" Post pissed me off so much. It''s a stupid phrase and should never be used. That post will do more damage to the community than 1 million "bad" questions.

Apologies if it offended anyone, but I feel the rest of the mail stands. A. -- Posted via http://www.ruby-forum.com/.

I agree with the principle, and I agree that it is real. As a reforming .NET user, I can attest to the pitiful state of many of the various communities because of this very real problem. Nothing is more frustrating than a list being overwhelmed with questions from those who won''t take the time to do a tiny bit of research before asking someone else to do it for them. A community is about give AND take. If you take too much, people ignore you, and if everyone only takes, then the community disintegrates.
