我想我们大多数人都遇到麻烦.htaccess我想知道是否有人可以帮助我.Opensuse 12.3:代码:

Linux linux-hyo0.site 3.7.10-1.16-desktop #1 SMP PREEMPT Fri May 31 20:21:23 UTC 2013 (97c14ba) x86_64 x86_64 x86_64 GNU/Linux

我喜欢在我的机器上安装Cakephp,但我的网页上有一个错误,上面写着"代码: 你的服务器上没有正确配置URL重写 ".

我的/ etc/sysconfig/apache2文件如下:代码:

APACHE_MODULES="authz_host actions alias auth_basic authz_groupfile authn_file authz_user autoindex cgi dir include log_config mime negotiation setenvif status userdir asis imagemap php5 reqtimeout authz_default rewrite"

并将/etc/apache2/sysconfig.d/loadmodule.conf作为最后一行代码:

LoadModule rewrite_module                 /usr/lib64/apache2/mod_rewrite.so

我也改变了我的文件etc/apache2/defaul-server.conf

<Directory />
    Options FollowSymLinks
    AllowOverride All
</Directory>
<Directory "/srv/www/htdocs">
    Options Indexes FollowSymLinks MultiViews
    AllowOverride ALL
    Order Allow,Deny
    Allow from all
</Directory>

有帮助吗？

在app/webroot上

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond …

我试图了解如何使用pdb .post_mortem() 方法。

对于这个给定的文件

# expdb.py
import pdb
import trace

def hello():
  a = 6 * 9
  b = 7 ** 2
  c = a * b
  d = 4 / 0
  print(c)

tracer = trace.Trace()

命令提示符

'''
# first Try

? python -i expdb.py
>>> pdb.post_mortem()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Program Files\Anaconda3\lib\pdb.py", line 1590, in post_mortem
    raise ValueError("A valid traceback must be passed if no "

这是我工作场所的一棵树。尝试读取我的resume.json文件时出现错误。

.
??? lib
?   ??? resume.json
?   ??? resume.rb
??? spec
    ??? resume_spec.rb
    ??? spec_helper.rb

此文件（resume.rb）在此调用（ruby resume.rb）上运行良好

文件resume.rb

require "json"

class Resume
  attr_accessor :name, :tel, :email, :experience, :education, :company

  def initialize
    file = File.read("resume.json")
    data = JSON.parse(file)
    @name = data.first.last
  end

end

resume = Resume.new
puts resume.name.size

但是当我运行规范时，出现此错误

.../resume.rb:7:in `read': No such file or directory @ rb_sysopen - resume.json (Errno::ENOENT)

文件resume_spec.rb

require "spec_helper"
require_relative "../lib/resume"


describe Resume do 

  before :each do
    @resume = Resume.new 
  end

  it "#Resume" …

我想创建一个像这样的json文件:

{"946705035":4,"946706692":4 ...}

我正在使用仅包含Unix时间戳的列并将它们分组.

result = data['Last_Modified_Date_unixtimestamp_no_time'].value_counts()

In [21]: result.head()
Out[21]: 
1508284800    131
1508716800    106
1508371200    101
1508457600     99
1508630400     96
Name: Last_Modified_Date_unixtimestamp_no_time, dtype: int64

变成一个字典

result = result.to_dict()
result
'''
{1507161600: 1,
 1507852800: 1,
 1508198400: 64,
 1508284800: 131,
 ...
 1535155200: 1,
 1535241600: 1}
'''

import json
result = json.dumps(result)

with open('result.json', 'w') as fp:
    json.dump(result, fp, indent=4)

结果 这是我期望的数据结构

{"946705035":4,"946706692":4}

我有以下错误：

django.core.exceptions.FieldError: 'pictures' cannot be specified for Building model form as it is a non-editable field

我有很多模型可以有很多图像。所以我使用了 django 的 GenericRelation。但只要我添加了“照片在”字段forms.py。我收到一个错误

表格.py

class BuildingForm(ModelForm):
    class Meta:
        model = Building
        fields = ['landlord', 'address', 'pictures']

模型.py

from stdimage.models import StdImageField

    picture = StdImageField(upload_to='pictures/%Y/%m/%d',

嗨,我想开始在一个奇妙的位置播放声音.api说我可以使用.pos但它不会从我希望它开始的地方开始
