python - How to refactor a large method when its components don't make sense on their own? -


I'm looking for a very large method to reactor on a diego models.Manager . For clarity (also my discretion), I would like to break it into my component parts.

This method takes an object, uses that object's information to load that webpage, and gives it a new or existing object from the database based on the content of that page.

We think that I'm trying to get vehicle the web page. In addition to other things, this may include:

  • Loading the page in question
  • Finding the vehicle's name from the page
  • If any 

    •   class vehicle manager (models. Manager): def getForSale (self, sales): # lots and many codes

    I would like to break it in smaller methods, each of which will be one of the bullet points .

    The ideological problem that I am facing is that I am not sure where small methods are kept, they are not related to vehicle manager / because:

    • There are no things I do do a set of code vehicle objects (e.g., Vehicle.objects.findNameOnPage
    • Many of them do not even use the example variable

    I can think of some ways to refactor it: / P>

    • Just create new ways, prefixel with underscore, eg: 

        def _findNameOnPage (self, page): # the self is not used < / Code>

      The problem with this approach is that the methods are more useful than actual methods.

    • Make steady ways: 

        @staticmethod def _findNameOnPage (page):

      Associates with methods (good), but to make such namespace false (false).

    • Place the methods in the form of a module area

      This does not disrupt the namespace (good), but also makes it less clear that the methods clas Are related to S (poor)

    Is there an acceptable form / way to get it in Python?

Where the path path is data in articles_tmp.path where the path is not zero . With SQLite , it does not work: update article SET path = (SELECT at.path FROM Articles_tmp as AS, WHERE at.article_id = a.id and a.asp, the text is in the form and not on. It has been transmitted) where the path is null MS Access Along with, it works fine: Update Articles Join the Inner Articles at articles_tmp articles.id = articles_tmp.id SETP articles.path = articles_tmp.path Can anyone help?

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ

I'm trying to gradually increase the font size of text on a web page. The code works in my place, although the new HTML / CSS does not render after every iteration of the loop and when all this is done, then display only the text of 100 px size. To see the text as if it is slowly zooming, I need to do this JavaScript is down because it is being used from a different file here is what I have ... < Pre> & lt; P class = "game-title" style = "font-size: 50px" & gt; Test & lt; / P & gt; Function sleep (milliseconds) {var start = new date ().
