merge_fixtures is having some problem parsing parameters with Python 3

[fuzzydolphin]

Using the following Python and Django

Python 3.4.6 Django 1.10.7

When I run the merge_fixtures command

python manage.py merge_fixtures foo.json bar.json baz.json > all_fixtures.json

It shows the following error message:

usage: manage.py merge_fixtures [-h] [--version] [-v {0,1,2,3}]
                                [--settings SETTINGS]
                                [--pythonpath PYTHONPATH] [--traceback]
                                [--no-color]
manage.py merge_fixtures: error: unrecognized arguments: foo.json bar.json baz.json

I looked into it a little bit and it seems to be unhappy in parsing the command line parameters. I think it is unhappy here:

        parser = self.create_parser(argv[0], argv[1])
        options = parser.parse_args(argv[2:])

But I am a bit unfamiliar with what is expected here and didn't have time to fully investigate the issue. Do you have a hint where I should be looking?

You need to add the following line in the merge_fixtures.py file:

def add_arguments(self, parser): parser.add_argument('args', metavar='files', nargs='+', help='One or more fixture.')

You can see it in the latest commit on master, but it doesn't seem to have been updated on PyPi, unfortunately.

i faced the same problem with django-fixture-magic installed from pypi. When replaced it with the latest installation from github, it works fine. pip install --upgrade git+https://github.com/davedash/django-fixture-magic.git

I guess that the Pypi-Version is not updated yet, because your commit https://github.com/davedash/django-fixture-magic/commit/3027e39f4dc4fb09d5ed1a0a22f28c2438525598

did not update the version number. If you increase the version number in setup.py, PyPi might recognise, that there is an update.

I added a similar add_arguments()-method to reorder_fixtures in Pull Request #61

[davedash]

@fuzzydolphin do @MaxBo's changes help?

[seanchon]

I experienced a similar issue as @fuzzydolphin while running reorder_fixtures and incorporating @MaxBo's suggestion solved it for me.

A year later and this is still an issue I wonder why this is even closed

[davedash]

I misread that it was fixed by #61. Reopening but it won’t be fixed unless someone’s got a PR for this.

[agalazis]

@davedash it's all about releasing what you have in master to pypi :)

PyPI deploy steps have changed slightly - https://stackoverflow.com/questions/45207128/failed-to-upload-packages-to-pypi-410-gone

[davedash]

The weird steps I remembered from the last time I did this worked :)

https://pypi.org/project/django-fixture-magic/

I really outta put this in Travis Dave Dash

Just ran into this error, confirmed it's fixed by using master:

pip install -e git+https://github.com/davedash/django-fixture-magic.git@master#egg=django_fixture_magic

 pip freeze | grep fixture
-e git+https://github.com/davedash/django-fixture-magic.git@466fa35c075009e4a1974f6e588471dd9e720e53#egg=django_fixture_magic

I also confirmed that the source files from PyPi do not match the ones on github master. PyPi still contains the old buggy copy of merge_fixtures.py.

I did a diff of the PyPi package's merge_fixtures.py file vs the github master's merge_fixtures.py.

As a workaround, I would need to package the correct copy on an internal devpi server myself, because unfortunately I cannot use github in the environment I am working on.

[davedash]

@mghantous Can you let me know if https://pypi.org/project/django-fixture-magic/0.1.5/ fixes things? This is from master.

[mghantous]

Hi @davedash you made me realize that I was actually on 0.1.3. I am unable to install 0.1.4 or 0.1.5. Maybe this is because I don't match requirements? But I thought it would be a different error message.

$ pip install django-fixture-magic==0.1.4

I'm using python 3.6 and django 2.2. Thanks.

[mghantous]

@davedash I think I may have identified the problem. If you navigate here you will see there is no 0.1.4 or 0.1.5 (but there is a version called 0.1.4.macosx-10.13-x86_64).

https://pypi.org/simple/django-fixture-magic/

I read in one article that you may need to do python setup.py bdist_wheel upload to get it to show up there.

[davedash]

I uploaded a wheel version and tried locally to verify that it now works. DOes this work for you?

Yes. And it appears merge_fixtures.py is the correct version off of master now. Thank you very much!

I am pretty sure this issue can be closed now.
