What is the Python egg cache (PYTHON_EGG_CACHE)? -


I have upgraded from Python 2.6.1 to 2.6.4 on my developer machine and presented on starting a dragon script The following was done with the following message:

Can not extract the file (files) in the egg cache

The following when trying to extract the file (files) in Python egg cache Error occurred:

[Errows 13] Permission denied: '/var/www/.python-eggs''

The python egg cache directory current Is defined in:

/var/www/.python-eggs

Perhaps your account does not have write access to this directory? You can change the cache directory by setting the PYTHON_EGG_CACHE environment variable to point to a directory.

There is nothing in it, so I have a little bit of any harm-

Can anyone tell me what is the Python Undo Cache?

In addition, can you explain that this is / is different because the site-package directory uses the dragon to store the eggs (as I think Am I

From my investigation it has come to know that some eggs are packed as zip files, And they are saved in Python's site-package directory.

These zipped eggs need to be unzipped before they can be executed, so it is expanded in the PYTHON_EGG_CACHE directory by default that ~ / .python-eggs (located in the user's home directory). If it does not exist, then it can cause problems in trying to run applications.

There are several fixes:

  1. Create a insert the Python-Egg directory into the user's home directory and make it usable for the user. .
  2. Create a global directory for unzipping (e.g., / tmp / python-eggs ) and set the environment variable PYTHON_EGG_CACHE in this directory.
  3. When using the install, use the -Z switch while using easy_install to open the package.

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
