extend Python namedtuple with many @properties? -


How many nicknames can be extended with additional @products?
For some, any text can write down; But there are many, so I am looking for a generator or property factory. One way is to generate text from _fields and exec exec; There will be one add_fields with the same effect on another runtime.
(My @props have to get rows and fields in the scattered database in several tables, so that rec.pname is context [Rec.personid] .pname ; But there are other uses in nametuples-with-smart-fields.) 

  Expand to designate with multiple @ properties? "" ("Person", "PNN peder") # ... tolerant = [person ("Smith", "NY"), person ("Jones", "IL")] class top (nominated ("top_ "," Topping amount was in vain ")):" Property "- family - for the continuous [person] .pname - & gt; Individual pad ..." "" __ slots_ = () @ property DP person (self ): Return [self.personid] with the same effect as return # def add_fields (auto, Top.person, person._fields) Return? @ Property Def PNA (self): Return from self.person.pname @property def paddr (self): Return Self Posters. PDDR # ... too much REC = top (0, 42, 1) print rbc, rec .pname, rec.paddr

Answer to your question

How can the named nail be expanded or additional @properties ?

can be sub-classified with: exactly the way you are doing this! What error are you getting? To see a simple case, 

  & gt; & Gt; & Gt; Square x (collections.nametuple ('y', 'a b c')): ... @property ... def D (self): return 23 ... & gt; & Gt; & Gt; A = x (1, 2, 3)> gt; & Gt; & Gt; AD D 23 & gt; & Gt; & Gt;

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...
