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
3027e39

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.

<     args = '[file ...]'

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.

@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? Dave Dash

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.
