No Image display - after uploading

Rails
1

Hi Everyone,
Atlast, i managed somehow to upload a file and read it. Here is
my code, dont know y “read” method didn’t work for me.

Controller:
def update
@content = Content.find_by_id(params[:id])
@content.updatedBy = session[:user_id]
@content.updatedOn = Time.now

File.delete(@content.picture) if File.exist?(@content.picture)
fileName = sanitize_filename(params[:content][:picture])

if params[:content][:picture] && params[:content][:picture].size > 0

File.open("#{RAILS_ROOT}/uploads/#{fileName}", ‘wb+’) do |f|

# f.write(params[:content][:picture].read)
@fileData = ""
f1=File.open(params[:content][:picture],'r') do |f1|
  while(line=f1.gets)
    @fileData=@fileData+line
  end
end
f.write(@fileData)
    end
end

params[:content][:picture] = "#{RAILS_ROOT}/uploads/#{fileName}"

if @content.update_attributes(params[:content])
  redirect_to :action => 'index'
else
  render :action => 'edit'
end

end

def sanitize_filename(file_name)
# get only the filename, not the whole path (from IE)
just_filename = File.basename(file_name)
# replace all non-alphanumeric, underscore or periods with
underscores
just_filename.gsub(/[^\w.-]/,’_’)
end

View:

Now, one more problem i got :frowning: the above code is working well if i
uploaded “text” file and read it manually. But the same is not going
well for “image” file.
The actual file size is around “120kb” but the uploaded file size
is only “2kb - 4 kb”. Also i couldn’t even see a bit of the image…

Can anyone help me… Please…

Thanks in advance

Some suggestions:

  1. Try file_column. It’s very easy.
  2. For your solution, try and render the page with the image, and then
    view the source of the rendered page in the browser. Take the url that
    is in the src= attribute, and paste it into your browser. That way you
    can determine if it’s a problem where you are placing the file in the
    filesystem, or if it is just a link issue.
  3. If you use updated_on or updated_at in your field of your table,
    rails will set it for you automatically. updatedOn is not recognized by
    rails.
  4. It looks like you are putting a full filesystem path into the src.
    This will not work, as your web server usually operates from a given
    directory. I can’t quite tell.

I would really recommend using file_column. It will reduce all your
code above to a couple of lines.
