Problem You have an input json with which you will create a list of objects, you have to validate that the object will be created if it not exists, if exists determine whether to upgrade or discard depending of they have not undergone any changes.

Solution 1) With the input json will be created the list of objects of the class that we insert or updatee

2) Read all fields in the database, using one of the fields as key to creating a dictionary with the objects in the database

3) Compare the objects and determine if it will be updated, inserted or discarded

Django problem: by default only compares the level objects using the primary key (id). Compare field by field is the solution to determine if the object has changed. hints: The _state field is present in every object, and it will produce a random memory location, You can find cache fields so you need to remove these begins with underscore _. The fields excluded can be fk, and these fields produce field_id, so you will needs to exclude it

Some times we have a share hosting without privileges, my goal for today, is set up a redmine instance in my hosting actually I have a instance with a2hosting, but i think it will be the same steps for others because I always work with my home directory

Currently I work with custom struct $HOME/.local for every local install and my custom temp dir is $HOME/.local/tmp

$HOME/.local/share
$HOME/.local/bin
$HOME/.local/lib
$HOME/.local/include
$HOME/.local/tmp
