python - Django Queryset Filter (Maybe Needs a Subquery) -


I want to generate a query to find mismatches. As an example 

  class vehicles (models.Model): car = model. Kharefild (max_length = 100) model = Model. Kharifild (max_long = 100) travelers = models.IntergrillField ()

I want to generate a query where I am with two different models You can get a listed car incorrectly.

On the lines of a question, to find out that car = Wrangler, Model = to find instances of the Jeep car = Wrangler, the model is not Jeep.

Is it possible to do within ORM, or do I need to use raw SQL? #django has suggested a subquery, but I am not familiar with how to do this

Sample output will be just a queryset of the incorrect matching vehicles (for example Car = wrangler, model = Ford exists for an object but car = wrangler, model = jeep for another object). I was thinking about not having an input which was just able to find mismatch. Does it still make sense?

If I think you need a model + the car is unique together, then you're repetitive Need to find the record:

django.db.models.aggregates from import repetitve_cars_list = vehicle.obages Price ('car') Anotate (count_car = calculation ('car')) .filter (co unt_car__gt = 1)

This will give you car which is more than one model

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
