How to iterate through multidimensional list/dict in a template

what is the difference between pool and prototype patterns?

QUESTION

How to iterate through multidimensional list/dict in a template

Asked 2019-May-19 at 19:17

I try to rebuild this example: https://blog.roseman.org.uk/2010/01/11/django-patterns-part-2-efficient-reverse-lookups/

I have a model "Product" and a model "Order". Order has a foreignkey to "product". So for 1 Product I have N Orders

In my template I have to display a lot of information so I would like to avoid to do "for order in Product.order_set.all()" in my template

In my template, if I write :

That is logical, since here Django interprets i not as the variable, but as the an identifier, so it aims to access object_list.i, or object_list['i'], not object_list.1 for example.

You however do not need i here, you can just access the related_items of the object, like:

QUESTION

what is the difference between pool and prototype patterns?

Asked 2018-Jun-14 at 20:14

I've just read the chapter on Creational patterns in the book Design Patterns in golang. These are:

factory
abstract factory
prototype
singleton
builder

I've created a repository on github to list all of them. I've looked for other repositories like mine:

Some list object-pool as a pattern, others simple-factory and factory-method. Does there exist an official list of creational patterns in go? Is it important to know the list, or is it more important to know what is possible and be able to use right code in right context? With or without know all the patterns in the world?

And, ... what is the difference between prototype and object pool patterns? They look very similar to me.

Design Patterns do not exist in isolation, they have relationships of their own. So for example, an object pool might use a factory or prototype to initially fill the pool or deal with exhaustion. The objects in that pool might conform to the command pattern, or be examples of the builder pattern.

In practice you cannot possibly know all the details of all patterns, the most important thing to know is the intent. What the pattern achieves. When using the pattern the remaining details can and should be taken from a pattern catalogue, over time you will learn some patterns comprehensively and reference others.

A Pattern Catalogue is the a collection of fully documented Design Patterns. The GoF Design Patterns book is probably the most famous Pattern Catalogue, however the book you mention and even github repositories can fulfil the same purpose.
