在3.2.12和3.2.11的导轨上进行了测试。在另一个Rails 3.2.11项目中，f.file_field并没有这个问题，但是在当前的项目中，我确实并且找不到这种奇怪行为的原因，所以这是我的问题。
我对更新操作有一个奇怪的问题。以下是相关代码部分:
路线:
get "signup" => "users#new", :as => "signup"
get "profile" => "users#profile", :as => "profile"
resources :users do
member do
get :activate
end
end
控制器:
def update
@user = User.find(params[:id])
if @user.update_attributes(params[:user])
redirect_to user_path(@user), :notice => t('users_controller.update.updated')
else
render :edit
end
end
以haml形式(简化，但具有相同的行为):
= form_for @user do |f|
.field
= f.label :first_name
%br
= f.text_field :first_name, :size => 40
.actions
= f.submit
因此，在按“更新”后，一切都会按预期进行，并且用户的属性也正在更新。但是，当我添加这样的文件字段时:
= form_for @user do |f|
.field
= f.label :first_name
%br
= f.text_field :first_name, :size => 40
.field
= f.label :avatar
%br
= f.file_field :avatar
.actions
= f.submit
然后按更新，然后出现路由错误:
No route matches [PUT] "/1"
我不明白为什么它尝试使用
/1方法到达PUT路径。在显示路由错误的页面上，我可以在浏览器的地址栏中看到/users/1。这是为表单生成的html:
<form accept-charset="UTF-8" action="/users/1" class="edit_user" enctype="multipart/form-data" id="edit_user_1" method="post"><div style="margin:0;padding:0;display:inline"><input name="utf8" type="hidden" value="✓" /><input name="_method" type="hidden" value="put" /><input name="authenticity_token" type="hidden" value="che8VLfDxDAoenma+TXwsA+0IQ7+/jbCIK+Q2xwr8uc=" /></div>
<div class='field'>
<label for="user_first_name">First name</label>
<br>
<input id="user_first_name" name="user[first_name]" size="40" type="text" value="Anton" />
</div>
<div class='field'>
<label for="user_avatar">Avatar</label>
<br>
<input id="user_avatar" name="user[avatar]" type="file" />
</div>
<div class='actions'>
<input name="commit" type="submit" value="Update User" />
</div>
</form>
所以，这是最有趣的事情。当我将表格更改为此时:
= form_for @user do |f|
.field
= f.label :first_name
%br
= f.text_field :first_name, :size => 40
.field
= f.label :avatar
%br
%input{:id => "user_avatar", :name => "user[avatar]", :type => "file"}
.actions
= f.submit
然后生成的html与前面的情况是一样的(我唯一看到的区别是，对于文件字段属性，使用单引号而不是双引号):
<form accept-charset="UTF-8" action="/users/1" class="edit_user" id="edit_user_1" method="post"><div style="margin:0;padding:0;display:inline"><input name="utf8" type="hidden" value="✓" /><input name="_method" type="hidden" value="put" /><input name="authenticity_token" type="hidden" value="che8VLfDxDAoenma+TXwsA+0IQ7+/jbCIK+Q2xwr8uc=" /></div>
<div class='field'>
<label for="user_first_name">First name</label>
<br>
<input id="user_first_name" name="user[first_name]" size="40" type="text" value="Anton" />
</div>
<div class='field'>
<label for="user_avatar">Avatar</label>
<br>
<input id='user_avatar' name='user[avatar]' type='file'>
</div>
<div class='actions'>
<input name="commit" type="submit" value="Update User" />
</div>
</form>
但是，提交此表单后，没有路由错误，一切都会按预期进行。
更新
实际上，它并没有按预期运行。我只是看了看
params哈希，发现存在:avatar密钥，但是我错过了在后一种情况下html的open标签中没有enctype="multipart/form-data"属性，因此不会上传文件。添加enctype=multipart/form-data属性会导致路由错误再次发生。我发现在提交多部分表单后尝试添加到
put ":id" => "users#update"时添加了redirect_to user_path(@user)路由(确保此路由不存在PUT的路由错误)，然后也存在路由错误No route matches [GET] "/users/users/1"。这是完整的
routes.rb:Myapp::Application.routes.draw do

有人知道吗
UPDATE2
揭示问题的原因在于多部分表单有助于找到有关同一问题的文章-Routing Error with Post/Put requests (Passenger Headers)，但不幸的是没有解决方案...
UPDATE3
我发现了一些有趣的东西。
/path_to_gemset_here/gem/journey-1.0.4/lib/journey/router.rb中有一个方法:def find_routes env
req = request_class.new env
routes = filter_routes(req.path_info) + custom_routes.find_all { |r|
r.path.match(req.path_info)
}
routes.sort_by(&:precedence).find_all { |r|
r.constraints.all? { |k,v| v === req.send(k) } &&
r.verb === req.request_method
}.reject { |r| req.ip && !(r.ip === req.ip) }.map { |r|
match_data = r.path.match(req.path_info)
match_names = match_data.names.map { |n| n.to_sym }
match_values = match_data.captures.map { |v| v && Utils.unescape_uri(v) }
info = Hash[match_names.zip(match_values).find_all { |_,y| y }]
[match_data, r.defaults.merge(info), r]
}
end
我检查了
env的非多部分请求和多部分请求，发现了这一点:非多部分:
"REQUEST_URI"=>"/users/1",
"SCRIPT_NAME"=>"",
"PATH_INFO"=>"/users/1"
多部分:
"REQUEST_URI"=>"/users/1",
"SCRIPT_NAME"=>"/users",
"PATH_INFO"=>"/1",
"SCRIPT_FILENAME"=>"/path_to_project_folder_here/public/users", - there is no such variable in a non-multipart request
所以这就是问题所在。正如我在方法的定义中看到的:
match_data = r.path.match(req.path_info)
PATH_INFO用于查找处理请求的路由，但在后一种情况下，由于某些将REQUEST_URI分为两部分而完全错误。不幸的是，目前我没有时间今天完成调查，希望我明天能够完成调查。如果有人有足够的好奇心比我更快地找到问题的根源，欢迎您:)
UPDATE4(编辑)
因此，这是调查的延续。

因此，问题显然出在将标头打包到哈希中的方式上-
PATH_INFO(还有其他标头)有两个值，而后一个(不正确)重写了第一个(实际上，问题在于这些标头正在发送，但我不知道该如何处理)。打包到哈希中是在split_by_null_into_hash(headers_data)方法中发生的。现在去那里。文件:
/path_to_gemset_here/gems/passenger-3.0.17/lib/phusion_passenger/utils.rb模块
Utils包含以下代码:if defined?(PhusionPassenger::NativeSupport)
# Split the given string into an hash. Keys and values are obtained by splitting the
# string using the null character as the delimitor.
def split_by_null_into_hash(data)
return PhusionPassenger::NativeSupport.split_by_null_into_hash(data)
end
else
NULL = "\0".freeze
def split_by_null_into_hash(data)
args = data.split(NULL, -1)
args.pop
return Hash[*args]
end
end
在我的情况下，条件的
if -part正在执行，所以现在问题出在PhusionPassenger::NativeSupport.split_by_null_into_hash(data)
这似乎带我们去归档:
/path_to_gemset_here/gems/passenger-3.0.17/ext/ruby/passenger_native_support.c未完待续...
UPDATE5
实际上，我决定不处理那个
C -file调试 hell ，因为我认为此文件是在乘客安装过程中编译的，并且要对其进行调试，我需要一次又一次地重新安装并重新安装passenger。因此，我决定切换到使用条件的else-部分，因为它似乎达到了完全相同的目标，但显然比预编译的C -code慢一点。但就我而言，这并不重要。因此，我通过使用以下代码将文件包含在/path_to_project_folder_here/lib文件夹中来覆盖方法的定义:module PhusionPassenger
module Utils
protected
NULL = "\0".freeze
def split_by_null_into_hash(data)
args = data.split(NULL, -1)
args.pop
return Hash[*args]
end
end
end
我无法更改
Hash[*args]的行为(更确切地说，可以通过重写::[]方法来实现，但我不想肯定)，因此我将对代码进行一些更改:module PhusionPassenger
module Utils
protected
NULL = "\0".freeze
def split_by_null_into_hash(data)
args = data.split(NULL, -1)
args.pop
headers_hash = Hash.new
args.each_slice(2).to_a.each do |pair|
headers_hash[pair.first] = pair.last unless headers_hash.keys.include? pair.first
end
return headers_hash
end
end
end
还有宾果!现在可以了。
但是，我不确定这样做是否会破坏其他功能，所以我不建议任何人使用这种方法。在遇到与此修改相关的任何问题之前，我将一直使用它。如果是这种情况，那么我将尝试寻找另一种解决问题的方法。
而且主要的问题仍然是为什么发送那些错误的标题。
最佳答案
使用以下代码在passenger_extension.rb文件夹中创建lib:
乘客3
module PhusionPassenger
module Utils
protected
NULL = "\0".freeze
def split_by_null_into_hash(data)
args = data.split(NULL, -1)
args.pop
headers_hash = Hash.new
args.each_slice(2).to_a.each do |pair|
headers_hash[pair.first] = pair.last unless headers_hash.keys.include? pair.first
end
return headers_hash
end
end
end
乘客5
module PhusionPassenger
module Utils
# Utility functions that can potentially be accelerated by native_support functions.
module NativeSupportUtils
extend self
NULL = "\0".freeze
class ProcessTimes < Struct.new(:utime, :stime)
end
def split_by_null_into_hash(data)
args = data.split(NULL, -1)
args.pop
headers_hash = Hash.new
args.each_slice(2).to_a.each do |pair|
headers_hash[pair.first] = pair.last unless headers_hash.keys.include? pair.first
end
return headers_hash
end
def process_times
times = Process.times
return ProcessTimes.new((times.utime * 1_000_000).to_i,
(times.stime * 1_000_000).to_i)
end
end
end # module Utils
end # module PhusionPassenger
然后在“config / application.rb”中执行以下操作:
class Application < Rails::Application
...
config.autoload_paths += %W(#{config.root}/lib)
require 'passenger_extension'
end
然后重新启动Web服务器。
注意:我不确定这不会破坏任何其他功能，因此使用此功能的风险由您自己承担，如果发现此方法有任何危害，请告知我。
