Re: Package a virtualenv to deploy across multiple systems?

2016-09-22 Thread ludovic coues

As long as you use similar hardware and the same OS version
everywhere, a zip should work. You might get some issue if each
machine have a different version of some lib on which python have
dependencies

Foreign key set template

2016-09-22 Thread jorrit787

I have a question about using *model.foreignkey_set* in Django templates. I 
was trying to use *model.foreignkey_set* to determine if there were any 
foreign keys for this model, but it appears that *model.foreignkey_set* 
returns something different than *model.foreignkey_set.all* - why is that? 
Shouldn't both return *None* if there are no foreign keys?

Just curious :)

Mock external api call (xero)

2016-09-22 Thread Karim

Hello everyone, I would like to test my code that call the xero api server
and to do that I want create mocked response to test different scenarios.

At the moment I want test just few endpoints, my Idea is to create a class
as a container of the items needed to render.

The items are generated by a class that use a "stamp" of the returned json
and add or modify the stamp using the given kwargs.

What you think about the example above? Maybe you have better idea?

e.g.

response = MockedXeroResponse()

invoice = fakeInvoice(**kwargs)  # kwargs add fields
another_invoice = fakeInvoice(**{'Amount':1000})

response.add(invoice, another_invoice)  #
response.json  # return the json response as the XERO api with the two
invoices.


Thank you

How to save images present in Django application directory to models

2016-09-22 Thread Krishn Bera

I am making a Django application that will do some sort of image 
manipulation. As an intermediate step, I am generating new images in the 
Django application directory. Now I want to save these images(.jpg) to a 
model that contains ImageField. How should I go about saving this image in 
database? Do we have any Django functionality that can upload images 
'programatically' to a database?

=the idea is to make all apps independent of OS=
Yeah! Docker do this. And any more... Docker can launch all parts of
application in independent containers. And you can make independent
scenarios and even load different libraries for different parts of
application. And with docker-composer you can make single scenario for all
containers and launch all of them with one command. And with docker-swarm
you can create scalable system.
