Is it OK to raise a built-in exception, but with a different message, in Python? -


Is it custom to enhance custom text? Or to take a single with custom text?

The document reads:

Exception value error: Arises when an underlying operation or function receives an argument (...)

Is it contained that only should the underlying operations take a ValueError exception?

In practice, I understand that it is safe to make exception class which is received by the error or exception but it is fine to do this, and directly to a value error ("custom Text ")?

As ValueError is built, by lifting a ValueError (with a custom text), users can quickly see whether the comparison of a custom exception type (like "ValueErrorSpecificModule", which is not standard) Includes the kind of problem. 

  increase ValueError ("invalid input encoding")

In fact, I do a lot of things often when I'm writing passes before some code. The main problem in doing this in such a way is that there is a hard time with the exception of your code client; In order to catch that specific exception, they must match the string on the exception object caught, which is clearly weak and tedious, thus implementing a ValueError subclass of your own would be better; It can still be caught as ValueError, but also as a more specific exception class.

A common rule of thumb is that whenever you have the code: 

 increase the value  ValueError (some problem:% s'% value)   
 You should change it like something: 
 
  class SomeProblem (ValueError): "" "to indicate a problem with the specified value." Increase some excite (value) You can say that the exception type specifies  what  went wrong, while the message / attributes  how  this has gone wrong 
 < / Div>  no The Rdisht.

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...
