configuration - How to exclude DEFAULTs from Python ConfigParser .items()? -


I am using ConfigParser to load data into the configuration file:

Test.conf: 

  [myfiles] fileone:% (DATADIR) s / somefile.foo filetwo:% (DATADIR) s / nudderfile.foo

load.py: 

  Import Configure Config = Config Piece. Config.read (configurable): config.items ('myfiles') print config.get (' myfiles', 'datadir')  ('' datadir ':' / tmp '}) config.read (' test .conf '  
  Output:  
 
  $ dragon load.py [('DATADIR', '/ tmp'), ('filetwo', '/ Tmp / nudderfile.foo '), (' fileone ',' /tmp/somefile.foo ')] / TMP  
 
 I'm afraid that variable replacement  (' Dattadir ',' '/ Tmp') are being shown as part of the default .  item ()  and  .get () , as if they were values ​​in the configuration file. Is this behavior expected? Any work around, so that I can just restart  .items () , without getting the default dictionary values, but still using magic interpolation? 
 
 Reference: 
 
 Thank you! 
 
  Update:  It has been indicated that this is expected behavior: the default in the configuration file is like a different name / value pair similarly, name / value pairs in the configuration file Also available for "magic interpolation", so if I define: 
 
  foo: bar: zap:% (foo) snowl  
 
 me < Code> [... ('zap': 'barnowl')] will get  
 
 It's very clean, but I'm still wondering if what I want to accomplish is Poo I can do the following: In my configuration files the name / value is reusable in pairs, with the launch of the variable, without defaults 
 
 My specific scenario is: I have the  config at  {atirir: '/ Foo / bar'}  because the full path is different for some files. Then I have to pass that configured object around and it must be repeated through the files. I do not want every class to know that the configuration should be read to know that it was started with some omission and it should be ignored because they are not actual files, is it possible? There is a way to hide default from .item () and .get () but still have interpolation? Thanks! Normally, I've found the class very useful, but there is a lack of it.  
 
 
 
 
 However, it may be ,  subclassed and expanded, sometimes well, sometimes it does not do so well (= very implementation dependent) 
 
 Here is the solution to your problem, tested in python3: 
 
  class ConfigParser (configparser.ConfigParser): "" "option () can get the" "default" def "option () Self, section, no_defaults = false, ** kwargs): if any_default: try: return list (excluding itself ._section [section]. Key ()) KeyError: raise NoS EctionError (section) Other: Returns Super (). Option (section, ** kwargs)  
 
 This is one of the worst examples, because it is partly copying  options () . It would be better if the configparser will provide the internal value of the base class  RawConfigParser  option  _options (self, section)  which will include the exception filter, and a  option ()  After that, in the sub-closing we will be using  _options () . 
 
 Can reuse for 2, I believe the only change is  super ()  code> super (config parser, self) . 
 
 You can then use: 
 
  Print Configuration. Use ('myfiles', no_defaults = true)  
 
 and also to repeat that list.

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...
