Re: Migrating from sqllite3 to postgres

[Luis Zárate]

Mmm probably you are looking for export /import data in django.

For export :
python manage.py dumpdata --format=json myapp > data.json

For import:
python manage.py loaddata data.json

See

https://docs.djangoproject.com/en/1.8/ref/django-admin/#loaddata-fixture-fixture

Re: How to use unlocalize in views

[julio . lacerda]

Thank You Luis, but it will be for the entire project, right? I just want 
to apply this to a single variable.

For example,

(float)
variable_x = 15.123  # Thousand separator from my L10N

variable_y = unlocalize(variable_x) 
print variable_y  # 15123

Do you know how can I do that without using a global directive?

I should add that the actual error is:

locate element: {"method":"id","selector":"id_login"}

because the main page never loads so it can't find the login button,

Testing Setup gives 500, but dev server works okay

[Timothy W. Cook]

I have a project that I started, then decided I should apply a TDD
approach.

Well the user registration and login portion already works but I am
attempting to add some tests to it.
The user can register, is redirected back to the main page with a Login
button.

Here is the test code:

def test_visitor_can_register_and_login_logout(self):
self.browser.get(self.server_url)
self.browser.find_element_by_id('id_register').click()
self.browser.find_element_by_id('id_username').send_keys(TEST_USER)
self.browser.find_element_by_id('id_email').send_keys(TEST_EMAIL)

self.browser.find_element_by_id('id_password1').send_keys(TEST_PASSWORD)

self.browser.find_element_by_id('id_password2').send_keys(TEST_PASSWORD)
self.browser.find_element_by_id('submit_registration').click()
time.sleep(10)
## Existing user is invited to login
self.browser.find_element_by_id('id_login').click()
self.browser.find_element_by_id('id_login').send_keys(TEST_USER)

self.browser.find_element_by_id('id_password').send_keys(TEST_PASSWORD)
self.browser.find_element_by_id('log_me_in').click()

## test user is logged in and can logout
self.browser.find_element_by_id('id_logout').click()
self.browser.find_element_by_tag_name('button').click()
##redirected back to main page
self.browser.find_element_by_id('id_login')

I see the main page load, the registration page loads and the inputs are
filled in.
When the submit_registion button is clicked I get a 500.  You can see I put
a sleep in there just so I could see it and verify that the process isn't
running too fast for the server to respond.

I originally had the registration and login in separate tests but I
understand that this might require TransactionTestCase ?  I am using
from django.test import LiveServerTestCase in this class.

I have one other test before that runs fine.

Any ideas?  Tips on troubleshooting this functional test?

You may have to edit the .sql file to make it work. Good luck.

Re: how to mock REST calls during development?

[Jirka Vejrazka]

Hi Abraham,

  I needed to solve this a few months ago, decided to use
https://github.com/getsentry/responses

  The way I did this is that I have a function that sets all required
responses (using the endpoint URL and the expected response in a file).
Then I detect in the application setup (apps, models, settings - whatever
you prefer) if I'm on a development machine and call that "mock_setup()" in
that case.

  Relatively simple code and no change required to my production views.

  Small sample at http://dpaste.com/0E1PNVQ

  HTH

How to use unlocalize in views

[julio . lacerda]

Hello guys!

Is there a way to use unlocalize in views? I know that I can use this in 
template 
(https://docs.djangoproject.com/en/1.8/topics/i18n/formatting/#localize)

updating members of modelformset with unique fields

[anentropic]

http://stackoverflow.com/questions/30425468/django-updating-members-of-modelformset-with-unique-fields

The situation - I have a model and inline formset like:

class ProductImage(models.Model):
product = models.ForeignKey('Product')
display_order = models.PositiveSmallIntegerField(default=0)

class Meta:
unique_together = (('product', 'display_order'),)

inlineformset_factory(
Product, ProductImage, form=ProductImageForm, extra=1)

In the front end I provide a UI to reorder the images for a given product.

The problem:

   - Let's say I already saved two images attached to .
   - These two images have display_order=0 and display_order=1 respectively.
   - now I upload a third image, give it display_order=0 while renumbering 
   the existing images to display_order=2 and display_order=1 respectively.

At this point I get a validation error for the unique check.

Looking through Django source code we find this in BaseModelFormSet.save:

return self.save_existing_objects(commit) + self.save_new_objects(commit)

...ok that looks all good, it will save (update) the existing objects 
first. So from the perspective of the db there is no conflict in the unique 
constraints.

The problem is that saving comes *after* validation, or course, and at the 
point of validation the new objects will conflict with existing ones in the 
db.

It seems like BaseModelFormSet needs some mechanism whereby it could take 
into account the about-to-be-updated values from its form instances.

Does anyone have a workaround that does not involve pushing the problem 
onto the user?

Re: how to mock REST calls during development?

how to mock REST calls during development?

[Abraham Varricatt]

Hello everyone,

I'm working on a Django application which needs to communicate with a 
3rd-party REST API. In production the flow would be like this;

   1. end-user browser sends a request to my django server
   2. my server makes a remote REST call to 3rd party server
   3. 3rd party server responds
   4. my server sends back response to end-user's browser

I'm simulating the above flow during development by using the Httpretty 
mocking library. Here is how my view looks like;

import httpretty

THIRD_PARTY_SERVER = http://api.gitlab.com/

def my_view(request):
if settings.DEBUG:
httpretty.enable()
httpretty.register_uri(httpretty.GET, THIRD_PARTY_SERVER, 
body='{some_mock_response_here}')

partner_response = requests.get(THIRD_PARTY_SERVER)

if settings.DEBUG:
httpretty.disable()
httpretty.reset()

# Do some stuff here
# ...

return render(request, 'template.html', context)



For the most part, the above works. I can experiment around without hitting 
the 3rd-party API. But it doesn't feel good. My mocking code is now part of 
the view function - not what I consider a good design. Problem is, I'm not 
sure how else this can be done? Does anyone have any better ideas? Note - 
I'm not doing any testing here. Just need a way to mock 3rd-party REST 
responses during development when I run "python manage.py runserver" for 
debugging/experimentation. 

Ideally, I'd like to move all the mocking code to it's own file and away 
from my views. This should somehow get activated when I start 'runserver' 
and work for all my views. 

Puzzled,
Abraham V.
