[英]Error uploading a file with rails
我想上傳帶有Rails的True Type字體,但收到此錯誤:
Encoding::UndefinedConversionError in FontsController#create
"\xE6" from ASCII-8BIT to UTF-8
這是控制器中的代碼:
def create
@font = Font.new(params[:font])
upload = params[:upload]
name = upload['datafile'].original_filename
@font.font_type = File.extname(name)
@font.location = './public/fonts/' + name
puts "\n\n---------------------------\n#{upload['datafile'].class}\n-----------------------------\n\n"
File.open(@font.location, "w+") { |f| f.write(upload['datafile'].read) }
#Save the license
@font.save
respond_to do |format|
if @font.save
format.html { redirect_to(@font, :notice => 'Font was successfully created.') }
format.xml { render :xml => @font, :status => :created, :location => @font }
else
format.html { render :action => "new" }
format.xml { render :xml => @font.errors, :status => :unprocessable_entity }
end
end
end
並在視圖中:
<%form_tag({:controller => 'fonts', :action=> 'create'}, {:multipart => true}) do%>
<% if @font.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(@font.errors.count, "error") %> prohibited this font from being saved:</h2>
<ul>
<% @font.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<%= file_field :upload, :datafile %>
<div class="actions">
<%= submit_tag "Upload License" %>
</div>
<% end %>
另外,使用其他方法上傳文件會更容易...對此有什么好辦法嗎? 謝謝
寫
File.open(@font.location, "wb") { |f| f.write(upload['datafile'].read) }
代替
File.open(@font.location, "w+") { |f| f.write(upload['datafile'].read) }
b模式以二進制模式打開文件。
