The goal of this PR is to add autotranslate and introduce German locale.

Adds:

• autotranslate django app
• make autotranslate command for automatically translating/updating existing translations

Langauge support for:

[
    ('en', _('English')),
    ('es', _('Spanish')),
    ('de', _('German')),
    ('hi', _('Hindi')),
    ('it', _('Italian')),
    ('ko', _('Korean')),

TODO:

Add mechanism to automatically replace poorly parsed special characters for python dynamic vars.
Example:

#: dashboard/templates/shared/nav_auth.html:54
#, fuzzy, python-format
#| msgid "Claim $%(tip.value_in_usdt_now)s Tip "
msgid "Claim $%(tip.value_in_usdt_now)s Tip "
msgstr "Claim $% (tip.value_in_usdt_now) s Tipp"

should be:

#: dashboard/templates/shared/nav_auth.html:54
#, fuzzy, python-format
#| msgid "Claim $%(tip.value_in_usdt_now)s Tip "
msgid "Claim $%(tip.value_in_usdt_now)s Tip "
msgstr "Claim $%(tip.value_in_usdt_now)s Tipp"

@owocki This PR should be good to merge - Test the latest at: https://stage.gitcoin.co -> Settings -> Preferred Language - Temporarily disabled zh (Chinese) and po (Polish).

[owocki]

LGTM once the concerns noted in slack are addresssed

[owocki]

@mbeacom go for it

Temporarily disabled zh (Chinese) and po (Polish).

How come ?

[owocki]

@PixelantDesign @mbeacom Do we want to auto-translate visitors based upon IP addresses?

#1695

[owocki]

oh also, it might be worth testing the emails @mbeacom

[mbeacom]

@owocki We can serve the appropriate language based on their Accept-Language header, enable language endpoints gitcoin.co/en, gitcoin.co/es, etc, use the ip aware tracking based on the locale of the IP, or simply use the preferred language established in settings. As it stands right now, the majority of the handling is done based on the user's preferences and based on the language header provided by the browser. I am not 100%, but the copy not displaying in the requested language might be a product of serving over CDN. 🤔

Also, testing emails now!

i think the Accept-Language header stuff is important for conversion (before the user has an account, i.e. upon first landing page visit)

got it. we should figure out the CDN issue before going live, since the prod site is on the CDN

[owocki]

@mbeacom this is a prioroity for decentralland -- any way we can prioritize shipping it?

[owocki]

@mbeacom what was the issue with chinese translation and is it fixed on this PR?

[mbeacom]

@owocki It was my mistake. I specified zh vs with the necessary secondary identifier zh-hant or zh-hans. They are present in this PR.
