Rather than manually pluralizing and passing too many variables, I would encourage using inflect library and making the function available as a filter in the template by utilizing Context Processors.

[machawk1]

@ibnesayeed That would be a good improvement but for now, this fixes the issue described in #534.

[machawk1]

inflect is also GPLv3, @ibnesayeed (related: #382)

[ibnesayeed]

I will leave the decision of merging this PR in its current state or otherwise to you discretion because I am not a big fan of hacky approaches on every step that pile up and make maintenance difficult (and invite more hacks for every new change).

[ibnesayeed]

inflect is also GPLv3

We can avoid using that, but still move the pluralization logic into Context Processors.

[machawk1]

@ibnesayeed Ok, I'll get a little more familiar with Flask's context processors and implement that with this same PR.

[machawk1]

@ibnesayeed I updated this to use a context processor. Please have another look.

./ipwb/replay.py:73:5: E731 do not assign a lambda expression, use a def needs to be fixed before we merge this.
