upload

I'm attempting to upload a csv file, parse it, and spit out a file for S3 or just pass to view. I use a file_field_tag to upload the csv. I thought file_field_tag passes an object that is a subclass of IO and would have all ruby IO methods such as "each_line". I can call "read" on the object (method of IO class) but not "each_line"... so how can I iterate over each line of a file_field_tag upload? create method of my controller as: @csv_file = params[:csv_file] My show view which throws a no "each_line" method error: <% @csv_file.each_line do |line| %> <%= line %> <% end %> Yet I can use <%=

i need a help on how to upload multiple files image on amazon S3. i let's say that i have three input like this <template lang="html"> <form enctype="multipart/form-data" @submit.prevent="sendFile"> <input type="file" ref="file1" @change="selectFile1"> <input type="file" ref="file2" @change="selectFile2"> <input type="file" ref="file3" @change="selectFile3"> <div class="field"> <button class="button is-info">Send</button> </div> </form> </template> and my frontend vue script looks like this <script> import _ from 'lodash' export default { name: 'BulkUpload', data() { return { file: "", message

In Django, I want to stop any file uploads that don't end in my designated extension as soon as they're received. To do this, I define a custom Upload Handler and write new_file to look something like this: def new_file(self, field_name, file_name, content_type, content_length, charset=None): basename, extension = os.path.splitext(file_name) if extension != ".txt": raise StopUpload(True) # Error: Only .txt files are accepted This works fine for stopping the upload but it also clears request.FILES. Now, when my view receives the request, it has no way to telling whether the upload handler

I've tried to use parse_on_demand as shown in: http://search.cpan.org/~flora/Catalyst-Runtime-5.80007/lib/Catalyst.pm#ON-DEMAND_PARSER However, I can't seem to stop the upload. I'm testing this simply by creating an action that dies immediately, however the browser seems to upload the very large file I've selected before it ever reaches my action: sub upload :Local { my ($self, $c) = @_; die; # What I'd like to do is this: # if ($c->req->header('Content-Length') > $some_limit) { # die "Upload too large"; # } # ... check filename extension and mime-type... } Is this the right way to approach
